CD151 Gene Delivery after Myocardial Infarction Promotes Functional Neovascularization and Activates FAK Signaling
Molecular Medicine volume 15, pages307–315(2009)
Our previous studies showed that tetraspanin CD151 promotes neovascularization in rat hindlimb and myocardial ischemia models. This study is to assess whether CD151 induces arteriogenesis and promotes functional neovascularization in a pig myocardial infarction model, and to determine the signaling pathways involved. CD151 cDNA and antiCD151 sequence were constructed into a recombinant adeno-associated virus (rAAV) vector. All 26 pigs used either were subjected to coronary artery ligation or did not undergo surgery. Eight wks after viral administration, the expression of CD151 protein was measured by Western blot. The densities of capillaries and arterioles were determined using immunohistochemistry. Regional myocardial perfusion and other myocardial functions were evaluated by 13N-labeled NH3 positron emission computed tomography (13N-NH3 PET) and echocardiography. Western blot was performed for assessing the signaling mechanisms. Overexpression of CD151 markedly increased the densities of capillaries and arterioles, significantly enhanced the regional myocardial perfusion, reduced myocardial ischemia, and improved the myocardial contraction, wall motion, and wall thickness. Conversely, antiCD151 gene delivery reversed the above changes. In addition, CD151 activated focal adhesion kinase (FAK), extracellular signal-regulated kinase (ERK), c-Jun N-teminal kinase (JNK), phosphatidylinositol-3 kinase (PI3K), protein kinase B (Akt), and endothelial nitric-oxide synthase (eNOS), and increased nitric oxide (NO) level. These findings demonstrate a robust role of CD151 in inducing and/or upregulating neovascularization. CD151-dependent neovascularization correlates with the activations of FAK, mitogen activated protein kinases (MAPKs), and PI3K signaling, suggesting that CD151 may promote neovascularization via MAPKs and PI3K pathways.
Myocardial ischemia is one of the most promising targets of gene therapy (1). Therapeutic angiogenesis aims to induce the formation of new blood vessels by delivering growth factors. Angiogenesis is the growth or sprouting of new capillaries from preexisting blood vessels which lack vascular smooth muscle cells (2,3). However, increasing evidence indicates that angiogenesis response is unlikely to contribute to the improvement the regional blood flow, as angiogenesis includes mainly new capillary blood vessels which are fragile and prone to rupture, and are unable to sustain proper circulation (2,4). In the case of occlusion of a major artery (coronary artery, and so on), preexisting arteriolar connections can be recruited to bypass the site of occlusion and arteriogenesis would occur. Arteriogenesis is the formation of arterioles, the remodeling of preexisting vessels into larger collateral arteries (1,2). Arteriogenesis is reported to be the mature form of new vessels and is able to provide enhanced perfusion. So, one major challenge of gene therapy is to induce an arteriogenesis response, leading to an efficient restoration of blood flow (1,2,5).
CD151, a tetraspanin superfamily protein, contains two extracellular loops, four hydrophobic transmembrane domains, and two short cytoplasmic tails (6,7). This tetraspanin is expressed broadly in various cell types and, characteristically, localized at perinuclear vesicles and cell-cell junctions in endothelial cells (ECs) (8,9). Functional studies have revealed a role for CD151 in regulating EC motility and in vitro angiogenesis (9–11). A recent study demonstrates that the mouse lung endothelial cells (MLECs) from CD151 null mice display marked reduction in the angiogenesis-related endothelial events including migration, spreading, invasion, Matrigel contraction, tube and cable formation, and spheroid sprouting (12). In parallel, transfection of CD151 cDNA into human umbilical vein ECs enhances cell proliferation, migration, and capillary tube formation on Matrigel (13). All these characteristics of CD151 strongly suggest that it can be useful for gene therapy to target myocardial ischemia by promoting angiogenesis. We have reported that CD151 gene delivery increases the number of microvessels in a rat myocardial ischemia model and a rat ischemic hindlimb model (14–15). Although CD151 is an important promoter for angiogenesis both in vitro and in vivo, it remains to be determined whether CD151 also induces the arteriogenesis response.
Previous studies have established that CD151 specifically binds to integrins such as α3β1, α6β1, and α6β4 (9,16–17). A primary role of CD151 is regulating integrin activity and function. For example: CD151 increases the activity of α3β1-integrin binding to laminin through stabilization of its activated conformation (18); CD151 strengthens α6β1 integrin-mediated adhesion to laminin-1 (16). In addition to the integrin association, CD151 links to signaling enzymes such as phosphatidylinositol-4 kinase and protein kinase C (17,19). Moreover, CD151 also is reported to form a structural and functional complex with hepatocyte growth factor (HGF) receptor c-Met, acting as a molecular controller for the HGF/c-Met signaling pathway (20). Therefore, CD151 modifies integrin-mediated outside-in signaling and may transduce its own signals through formation of multimolecular complexes with other membrane proteins (19–21). Few studies have explored the molecular mechanisms of CD151 in angiogenesis (13,15,22). Further, the explicit signaling mechanism by which CD151 regulates blood vessel formation and maintenance has not been well elucidated.
Large animal models are necessary for research on gene therapy approaches (1). In the present study, we chose a porcine model for gene transduction. We used a strategy of direct intramyocardial administration of a recombinant adeno-associated virus (rAAV) construct coding CD151 in pigs with coronary ligation. An antiCD151 was constructed using antisense nucleic acid technique to downregulate the expression of CD151. The purpose of this study was to evaluate whether CD151 induces angiogenesis and arteriogenesis, and to determine the signaling pathways involved. We showed that focal adhesion kinase (FAK), mitogen-activated protein kinases (MAPKs), and phosphatidylinositol-3-kinase (PI3K) signaling pathways played differential roles in CD151 signal transduction.
Materials and Methods
Plasmids and Antibodies
The pZeoSV-CD151 plasmid was described in an earlier study (13,14). Anti-CD151(sc-18753), anti-von Willebrand factor (vWF), (sc-73268) anti-FAK (sc-558), anti-phospho-FAK925 (sc-101680), anti-PI3K (sc-1404), anti-Akt (sc-5298), anti-phospho-Akt (sc-101629), anti-p38MAPK (sc-535), anti-phospho-p38MAPK (sc-7973), anti-c-Jun N-terminal kinase JNK) (sc-571), anti-phospho-JNK (sc-6254), anti-c-Jun (sc-1694), anti-phospho-c-Jun (sc-7981), anti-β-actin (sc-47778), and anti-smooth muscle (SM) α-actin (sc-130616), anti-extracellular signal-regulated kinase (ERK) (sc-94), and anti-phospho-ERK (sc-16982) antibodies were purchased from Santa Cruz Biotechnology (Santa Cruz, CA, USA). Anti-phospho-FAK397 (44624G), anti-phospho-endothelial nitric-oxide synthase (eNOS) (44307M), and anti-eNOS antibodies (334600) were from Biosource International (Camarillo, CA, USA).
Preparation of rAAVs and Quantitation of Viral Titers
The packing and production of the rAAV-GFP, rAAV-CD151, and rAAV-antiCD151 were carried out using a triple-plasmid cotransfection method in 293 cell lines. The plasmid pXX2 (for serotype 2) and the adenovirus helper plasmid pHelper were made and a total of 85 mg of plasmid DNA were used for transfection (the molar ratios of dsAAV-GFP, dsAAV-CD151, or dsAAV-antiCD151 to pXX2 and pHelper were 1:1:1). Then the single step gravity-flow column purification method was applied (25). The eluted rAAVs were divided into aliquots and stored at −80° C. The titer of vector particles was determined by the quantitative DNA dot-blot hybridization of DNase I-treated vector stocks.
Animal Preparation and Gene Delivery
Twenty-six purebred male pigs (Animal Resource Center, Huazhong Agriculture University, Wuhan, China), weighing 22–26 kg, 3 months of age, were housed at our institution for a minimum of 1 wk prior to use. They received normal swine food. The animals were randomized into four groups. Four normal pigs underwent no operation and served as the control group. The remaining 22 pigs served as three viral-administered groups, and underwent coronary artery ligation and received intramyocardial viral injection.
Briefly, the pigs were sedated with intramuscular diazepam (0.05 mg/kg), atropine (0.05 mg/kg), and ketamine (20 mg/kg), and then intubated. Sedation was maintained with sodium thiopental (2.5–4 mg/kg/h) and pancuronium (0.1–0.15 mg/kg/h). A limited left thoracotomy was performed asceptically through the fifth intercostal space, and a small incision was made in the pericardium. The heart was exposed and suspended in a pericardial sling. A silk suture was set at the immediate distal end of the second branch of the left anterior descending (LAD) coronary artery and ligated 20 min later. Coronary occlusion was confirmed by the presence of raised segment (ST) stages on the electrocardiogram and ventricular arrhythmias within the first 10 to 20 min after occlusion (ST is the part of an electrocardiogram immediately following the QRS complex and merging into the T wave). Simultaneously with the LAD ligation, all remaining animals received direct intramyocardial injection of rAAV-CD151, rAAV-antiCD151, and rAAV-GFP (1 × 1012 virons per pig, in 2 mL phosphate buffered saline, pH 7.4), respectively, in the ischemic area along the two sides of the ligated LAD coronary artery (10 sites for each animal and 5 for each side with ∼1-cm interval). The injection sites were marked with India ink for subsequent identification. Experimental protocols complied with the Guide for the Care and Use of Laboratory Animals and were approved by the Chinese Academy of Sciences.
Assessment of the Regional Myocardial Perfusion
Regional myocardial perfusion was evaluated at 3 d and 8 wks after the viral administration by means of 13N-labeled NH3 positron emission computed tomography (13N-NH3 PET). The pigs were placed in the dorsal (supine) position and PET scans were performed with 15-cm axial field of view (DISCOVERY LS-GE, Milwaukee, WI, USA) over the cardiac region. PET images were acquired in 2D mode, starting 20 min after intravenous injections of 555 to 740 MBq (15 to 20 mCi) bolus of 13N-NH3. During the PET scans, animals were maintained under general anesthesia as described above. Transaxial cardiac images were then reoriented into horizontal long-axis, vertical long-axis, and short-axis images with a thickness of 4.25 mm. Three axis views were analyzed further.
Echocardiographic Assessment of Regional Myocardial Function
The same zones for each animal were analyzed by echocardiography at 3 d and 8 wks after viral administration. The pigs were sedated and placed in the left lateral decubitus position, and standard two-dimensional and M-mode transthoracic images were obtained with a Vivid 7 Dimension echocardiographic machine (GE Healthcare, Waukesha, WI, USA) and a 1.5 to 4.0 MHz frequency transthoracic transducer. From the right parasternal approach, short-axis, midpapillary views were obtained at rest for 3 min. Regional wall thickening, myocardial contractile function, and wall motion were determined by a single experienced investigator in a blinded fashion. These images and parameters were recorded for subsequent review and analysis.
Immunohistochemistry Analysis and Data Acquisition
Heart tissue samples were taken from the region of the left ventricle around the previously marked sites 8 wks after viral administration and cut into 4-µm thick sections. Some sections were stained with hematoxylin and eosin (H-E). Some sections were used for immunohistochemical staining with vWF and SM α-actin antibodies, respectively, for capillaries and arterioles correspondingly.
The densities of capillaries and arterioles were evaluated according to the methods previously described (5,26). The five blood vessel-rich regions were selected, and the vessels within the 400× microscopic field of each region were counted by two blinded investigators without knowledge of groups. The densities of capillaries (positive vWF stain) and arterioles (positive SM α-actin stain) in each field were evaluated by counting vessels in a total of five high-powered fields (HPF) per region per heart under ocular micrometers (Olympus Optical Co. Ltd., Tokyo, Japan).
Measurement of Nitric Oxide Concentration
At 8 wks after vector administration, all five tissue samples were taken from the ischemic heart region in one pig around the previously marked sites. The levels of nitric oxide (NO) were measured using the NO detection kit (Jingmei, China) by following the protocol exactly as provided by the manufacturer. In brief, the sampled myocardial tissues were homogenized and reacted with nitrate reductase in the presence of cofactor. The NO concentration was calculated for these parameters as: NO (µmol/L) = Sample OD/Standard OD × 100.
All five tissue samples were taken from the ischemic heart region around the previously marked sites in one pig 8 wks after vector administration. To investigate the effects of rAAV-CD151 treatment on myocardial tissue protein expression, proteins were extracted, quantified, and separated by SDS-polyacrylamide gel electrophoresis (PAGE) as described previously (14). Western blots were probed with antibodies against CD151, phospho-FAK, FAK, PI3K, phospho-Akt, Akt, phospho-eNOS, eNOS, phosphop38MAPK, p38MAPK, phospho-JNK, JNK, phospho-c-Jun, c-Jun, and β-actin. The intensities of the various protein bands were quantified by densitometry.
Data were expressed as the mean ± standard error of the mean (SEM). Comparisons of parameters were performed by one-way analysis of variance (ANOVA), followed by the Newman-Keuls test for unpaired data. Comparisons of parameters between two groups were made by unpaired Student t test. P values of <0.05 were regarded as statistically significant.
Of the total 26 pigs that entered the study, 22 pigs (control group, n = 4; rAAV-GFP group, n = 6; rAAV-CD151 group, n = 6; and rAAV-antiCD151 group, n = 6) survived throughout the study, without any clinical sign of toxicity. Four pigs died during the experimental surgery or at the stage of multiple analyses. The three viral administered groups (rAAV-GFP group, rAAV-CD151 group, and rAAV-antiCD151 group) exhibited evidence of myocardial infarction in the ligated distal LAD coronary artery region, as demonstrated by (1) a fixed defect in the LAD coronary artery zone of the 13N-NH3 PET images, (2) a thinned, akinetic region of the left ventricle during echocardiography, and (3) large chaotic fibrous tissues, instead of normal regular cardiocytes, in the H-E staining of myocardial tissue.
CD151 Gene Delivery Increases the Expression of CD151 Proteins
Western blot analysis showed that the in vivo expression of CD151 proteins was increased significantly in the rAAV-CD151 group compared with the control and rAAV-GFP groups, but decreased in the rAAV-antiCD151 group (Figure 1A, B). There was no significant difference between the control and rAAV-GFP groups in the CD151 expression. These results indicate that rAAV-mediated CD151 gene delivery promotes the CD151 protein expression in myocardial tissue.
rAAV-CD151 Increases the Densities of Capillaries and Arterioles
Formation of capillaries and arterioles was evaluated by vWF-positive and SM α-actin-positive vessels at 8 wks after the viral transduction (Figure 2). The CD151 gene, transferred to ischemic myocardium, enhanced the densities of capillaries and arterioles compared with the control group and the rAAV-GFP group. In contrast, capillary and arteriole densities were decreased in the rAAV-antiCD151 group compared with the rAAV-GFP group. These findings indicate that CD151 gene delivery increases the formation of capillaries and arterioles, and enhances both angiogenesis as well as arteriogenesis responses.
Effects of rAAV-CD151 Delivery on Myocardial Perfusion
The 13N-NH3 PET image data was used to display the myocardial perfusion and the severity of myocardial ischemia. The control group for myocardial perfusion in normal pigs exhibited no detectable defect (Figure 3A). In the three viral transduced groups, PET images obtained at 3 d after viral transduction displayed similar myocardial perfusion with a characteristic perfusion defect, mainly at apical, anterior, and some septal regions. At 8 wks after viral administration, the rAAV-CD151 group exhibited significantly improved myocardial perfusion compared with the rAAV-GFP group. This improvement was found at the anterior and septal regions. However, perfusion in the rAAV-antiCD151 group worsened and most images revealed hyperdispersion and decreased perfusion (Figure 3B–D).
Together, these data indicate that rAAV-CD151 treatment significantly promotes the myocardial blood perfusion and reduces myocardial ischemia.
Effects of rAAV-CD151 Delivery on Myocardial Function
The effects of rAAV-CD151 delivery on the myocardial function were examined by echocardiography. Myocardial function and regional wall motion were reduced 3 d after vector administration in all three viral administration groups compared with the control group (Figure 4A–D). There was no significant difference of wall thickness in these four groups (Figure 4E, F).
In contrast, by 8 wks after vector administration, the increased left ventricular ejection fraction (LVEF%) and left ventricular shortening fraction (LVFS%) were found in the rAAV-CD151 group compared with the rAAV-GFP group, which showed marked improvement in myocardial contractile function (Figure 4A, B). The regional wall motion, verified by anterior lateral wall systolic thickening fraction (AALWT%) and interventricular septal systolic thickening fraction (ΔIVST%), showed further improvement in the rAAV-CD151 group compared with the rAAV-GFP group (Figure 4C, D). The septal and anterior lateral wall diastolic thickness, according to anterior lateral wall diastolic thickness (ΔLWTd) and interventricular septal diastolic thickness (IVSTd), both were increased in the rAAV-CD151 group (Figure 4E, F). LVEF% and LVFS% were decreased in the rAAV-antiCD151 group compared with rAAV-GFP group. The rAAV-antiCD151 group showed deteriorated heart function. However, there was no significant difference in septal and anterior lateral wall diastolic thickness between rAAV-antiCD151 group and rAAV-GFP group. These results demonstrate that rAAV-CD151 transduction results in enormous improvement of myocardial contractile function and wall motion, and significant increases in wall thickness.
Effects of rAAV-CD151 Delivery on Signaling Pathway
The effects of rAAV-CD151 delivery on the FAK, MAPKs, and PI3K/Akt/eNOS signaling pathways were examined. Western blot analysis showed CD151 expression significantly elevated phosphorylation-dependent activation of signaling components, such as FAK, ERK1/2, JNK, and c-Jun (Figure 5A–D). Both phospho-FAK397 and phospho-FAK925 were increased in the rAAV-CD151 group. By contrast, the level of phospho-p38MAPK proteins demonstrated no significant difference among the four groups, which suggests overexpression of CD151 did not affect the activity of p38MAPK protein.
Our study demonstrates that CD151 also activates the PI3K/Akt/eNOS pathway. PI3K expression, phospho-Akt, and phospho-eNOS protein levels were increased in the CD151-transfected myocardium and the NO concentration also was higher, compared with both the control group and the rAAV-GFP group (Figure 5E–G). In contrast, such changes all were reversed in the rAAV-antiCD151 group. Taken together, these results suggest that overexpression of CD151 activates FAK, ERK1/2, JNK, and PI3K/Akt/eNOS signaling pathways.
Blood flow tends to depend more on arterioles than on capillaries, which lack vascular smooth muscle cells (2–5). An arteriogenesis response, which consists of the formation of new arterioles, can occur. These vessels, implicated in arteriogenesis, are microvascular, thin-walled conduits composed of an endothelial lining, an internal elastic lamina, and one or two layers of smooth muscle cells. These arteries have the ability to provide enhanced perfusion to the jeopardized ischemic regions (4). In addition, because collateral arteries require a functional capillary network for effective exchange of oxygen and nutrients, angiogenesis and arteriogenesis are connected tightly and both are important to myocardial perfusion (1).
Our previous studies have indicated that in vivo CD151 gene delivery increases the number of capillaries and induces an angiogenesis response in different models (14,15). These previous studies, however, did not address whether CD151 induces arteriogenesis or promotes myocardial perfusion. The present immunohistological data suggest CD151 gene delivery induces both angiogenesis and arteriogenesis as evaluated by the increases in capillary density and SM-coated arteriole density, respectively. Further data from 13N-NH3 PET imaging and echocardiography demonstrated that CD151-induced neovascularization can efficiently enhance the myocardial perfusion and ameliorate the regional myocardial dysfunction. Herein, rAAV-mediated CD151 gene delivery promotes the functional neovascularization, resulting in a marked enhancement of formation of neocapillaries and new arterioles and an increase in the regional blood flow recovery.
The extensive analysis of the CD151 signaling revealed some interesting observations. Activations of FAK, Src, p38 MAPK, JNK, and c-Jun, but not ERK1/2, are required for the CD151-dependent enhancement of cell migration and cell-to-cell adhesion in MelJuSo melanoma cells (21). However, other studies found that the overexpression of CD151 has no effect on the adhesion-dependent activation of FAK, but specifically attenuates the adhesiondependent activation of ERK1/2 and PKB/c-Akt (27,28). Furthermore, Takeda et al. showed that the adhesion-dependent activation of PKB/c-Akt and eNOS is diminished in CD151-null MLECs while the activities of ERK, p38 MAPK, FAK, and Src are unaltered (12). The present study analyzed CD151 delivery and demonstrated that CD151 transduces signals leading to the activation of MAPKs and PI3K/Akt/eNOS pathways. FAK (phospho-FAK397 and phospho-FAK925), MAP kinases (phospho-ERK1/2 and phospho-JNK), Akt (phospho-Akt), and eNOS (phospho-eNOS) all were activated in the rAAV-CD151 group. As JNK plays a role of upstream effectors for c-Jun, the phospho-c-Jun protein level was increased and c-Jun was activated further. We also found that the PI3K protein level and NO production were upregulated by CD151 gene transfer. In contrast, when the expression of CD151 was reduced, the activities of these signaling proteins were decreased significantly.
The FAK pathway is one of the most important integrin-mediated signaling pathways. Earlier studies demonstrated that CD151 promotes cell migration and invasion in an FAK-dependent manner (29). Additional studies link integrindependent activation of MAPKs and PI 3-kinase with FAK (30,31). Phosphorylation of FAK at Tyr925 residues or the full activation of FAK may induce the activation of Ras-MAPK pathway (31). Phosphorylation of FAK on tyrosine 397 induces assembly of the FAK-PI 3-kinase complex and activation of this lipid kinase (30). It is very likely that FAK connects the CD151 signaling to MAPKs and PI3K (Figure 6). Therefore, CD151 gene transfer activates FAK-MAPKs and FAK-PI3K signaling pathways.
Angiogenesis is a complex process involving EC proliferation, migration, remodeling of extracellular matrix, and formation of tubular structures. Vascular endothelial growth factor (VEGF) is considered one of the most important growth factors in angiogenesis. However, a previous study has shown CD151-induced angiogenesis is not mediated by VEGF (15). How CD151 promotes angiogenesis at the molecular level needs to be defined. Although we demonstrated that the activation of MAPKs and PI3K signaling pathways were involved in CD151 signal transduction, whether these signal pathways play essential roles in CD151-induced angiogenesis is still uncertain. MAPKs, including ERK1/2, JNK, and p38MAPK are the major signal transduction molecules responsible for cell proliferation, migration, and a variety of cellular responses in angiogenesis (32,33). Many growth factors and hormones that may regulate angiogenesis activate MAPKs and/or PI3K/Akt signaling pathways (34-36). In addition, previous studies have shown the FAK, MAPKs, and PI3K are involved in CD151-enhanced cell migration (21,29,37). Our earlier study demonstrated that activation of PI3K/Akt signaling pathway mediates CD151-induced EC proliferation and migration, and that activation of PI3K/Akt is crucial to events in CD151-mediated angiogenesis in vitro (13,22). Therefore, CD151 likely promotes angiogenesis and arteriogenesis, at least in part, through activation of MAPKs and PI3K pathways.
In conclusion, we have demonstrated that intramuscular transduction of rAAV-CD151 actually promotes functional neovascularization, and both angiogenesis and arteriogenesis responses, in a pig myocardial ischemia model, leading to a greater enhancement of blood flow restoration. This is the first time a relationship between CD151 and arteriogenesis has been detected and the first proposition of a mechanism model of CD151, which connects CD151 with FAK-MAPKs and FAK-PI3K pathways. Our findings suggest that CD151 could be a new and efficient target for neovascularization, and these data are potentially important for the clinical development of gene therapeutic approach.
