| 摘 要： | 背景：整合素连接激酶在调节细胞生存、抗凋亡以及促进细胞迁移、增殖、分化等方面发挥重要作用。目的：观察整合素连接激酶在新生大鼠心肌细胞内高表达后对心肌细胞增殖能力的影响。方法：取新生3d内SD大鼠心脏,体外分离、培养心肌细胞72h后,分别转染重组腺病毒载体或重组腺病毒载体＋整合素连接激酶基因。结果与结论：转染48h,与转染重组腺病毒载体比较,转染重组腺病毒载体＋整合素连接激酶基因的新生大鼠心肌细胞内DNA合成增加（P〈0.05）,有丝分裂增多（P〈0.05）,心肌细胞数量增多（P〈0.05）。在整合素连接激酶的作用下,新生大鼠心肌细胞的增殖能力明显提高。

| Abstract: | BACKGROUND：Integrin-linked kinase plays an important role in regulating cell survival and anti-apoptosis to promote cell migration, proliferation, and differentiation. OBJECTIVE：To explore the effects of over-expressed integrin-linked kinase on cardiomyocytes proliferation in neonatal rats. METHODS：The heart of neonatal rats （1–3 days old） was extracted to in vitro isolate and culture cardiomyocytes for 72 hours. Then, the cells were transfected with recombinant adenovirus vector or recombinant adenovirus vector＋ integrin-linked kinase gene. RESULTS AND CONCLUSION：Compared with the recombinant adenovirus vector group, there was an increase in DNA synthesis （P 0.05）, mitosis （P 0.05） and the number of cardiomyocytes （P 0.05） in the recombinant adenovirus vector＋ integrin-linked kinase gene group. Briefly, integrin-linked kinase can promote the proliferation of neonatal rat cardiomyocytes. |
