摘要
本研究旨在探讨耐力训练加维生素E和不加维生素E对雄性大鼠前列腺p53、磷酸酶和张力同源(PTEN)肿瘤抑制基因表达的影响。为此,将50只雄性Sprague-Dawley大鼠随机分为5组:(1)对照组(CON, n = 10),(2)假手术组(S, n = 10),(3)耐力训练组(ET, n = 10),(4)耐力训练+维生素E (ET + VE, n = 10),(5)维生素E (VE, n = 10)。耐力训练方案实施6周,每周6天,按照过载原则。采用实时荧光定量PCR法测定大鼠前列腺组织中p53和PTEN基因的表达变化,HPLC法测定大鼠前列腺组织中维生素E的含量。服用维生素E 6周后,除VE组外,其余各组维生素E水平均显著高于对照组(p
The effect of endurance training with and without vitamin E on expression of p53 and PTEN tumor suppressing genes in prostate glands of male rats
The aim of this study was to investigate the effect of endurance training with and without vitamin E on the expression of p53 and Phosphatase and tension homolog (PTEN) tumor suppressor genes of prostate glands in male rats. For this purpose, 50 Sprague–Dawley male rats were randomly assigned into 5 groups: (1) control group (CON, n = 10), (2) sham (S, n = 10), (3) endurance training (ET, n = 10), (4) endurance training + vitamin E (ET + VE, n = 10), (5) vitamin E (VE, n = 10). Endurance training protocol was implemented for 6 weeks, 6 days per week, in accordance with the overload principle. To measure expression changes of p53 and PTEN genes in rats' prostate, real-time PCR method was used and HPLC method was used to measure vitamin E in this tissue. After 6 weeks of taking vitamin E, its level in all groups, except for group VE (p < 0.000) did not significantly increase. After implementing training protocol, p53 expression reduced significantly in ET group (p < 0.026). Vitamin E supplementation along with endurance training did not cause any significant change either p53 or PTEN (respectively; p < 0.2, p < 0.11). Instead, vitamin E supplementation without endurance training caused significant increase in PTEN, but did not cause any significant changes in p53 (respectively; p < 0.016, p < 0.15). These results indicate that endurance training reduces p53 and PTEN tumor suppressing genes expression, and taking vitamin E supplement could increase expression of these genes in some extent.
