白细胞介素－4调控糖代谢相关基因LDH-A诱导前列腺癌细胞PC3的增殖

摘要

Objective To study the effects of IL-4 in prostate cancer cells glycometabolism and proliferation. Methods We used IL-4 to treat PC3 cells, then tested the changes of LDH-A expression by RT-qPCR, Western Blot, CCK-8 and lactate production assay. Results Our data showed that IL-4 induced LDH-A up-expression in PC3 cells at mRNA and protein levels. Also, IL-4 promoted the proliferation activation and increased lactate production in PC3 cells. Conclusion IL-4 can strengthen the proliferation activation in PC3 cells by up-regulating LDH-A expression.%目的：研究白细胞介素－4（ IL-4）对前列腺癌细胞糖代谢和细胞增殖的影响。方法：IL-4处理前列腺癌细胞 PC3，利用 RT-qPCR、Western Blot、细胞增殖实验（ CCK-8）以及乳酸测定实验，观察 IL-4对乳酸脱氢酶A（LDH-A）的变化和细胞增殖的影响。结果：经过IL-4处理的前列腺癌细胞PC3，LDH-A的mRNA表达量（P ＜0．05）、蛋白表达量（P ＜0．05）明显升高，并促进PC3细胞的增殖（P ＜0．01）和乳酸产生（P ＜0．01）。结论：IL-4影响前列腺癌细胞的糖代谢，上调糖代谢相关基因LDH-A的表达，从而促进前列腺癌细胞的增殖。
