Popis: We have previously shown that immature tubules are resistant to anoxia compared to mature tubules. This tolerance is accompanied by an exuberant production of activated heat shock transcription factor. To further assess the role of the stress response, in vivo ischemia was produced in immature and mature rats. Immature rats (IR), age 10 days, and mature rats(MR), age 10 weeks, underwent 45 min of bilateral renal artery ischemia(BRAI); 24 hrs later, serum creatinine (Cr) was drawn and kidneys were prepared for histologic evaluation. Serum Cr (mg/dl) confirmed tolerance to ischemia (I): non-I: 0.60 ± 0.03 IR, 0.45 ± 0.05 MR, (P=NS), I: 0.66 ± 0.02 IR; 2.5 ± 0.57 MR (p
