title: [Quantitative detection of GSTP1 gene sin the lung tissue of hypobaric hypoxia modeling rats].
abstract: We have investigated the susceptibility of rat lung's GSTP1 gene to hypobaric hypoxia and explored its role in the body's possible adaptation mechanism at the moleuclar lever. Thirty male SD rats were randomly divided into five groups(0,1,3,5 and 7 d) and were exposed for 12 h per day at a simulating altitude of 7000 +/- 50 m in a hypobaric hypoxia chamber with 1 h's rest after 6 h's exposure. Then the expression of GSTP1 mRNA in the lung tissue of SD rats was examined using fluorescence quantitative RT-PCR. Meanwhile the activity of glutathione S-transferases (GSTs) enzyme and the change of maleic dialdehyde (MDA) in the lung tissue of SD rats were determined using spectrophotometer. In comparison with the non-exposure group,the expression of GSTP1 gene showed statistically significant differnce from the first to the seventh day (P<0.05). The level of GSTs decreased and MDA increased from the first to the seventh day (P<0.05). In conclusion, GSTP1 gene is susceptible to hypobaric hypoxia and may be a new marker of gene screening for the body's adaptation to special environment.
