Background/Aim: Among various kidney disease models, there are few rat glomerulonephritis (GN) models that develop in a short time, and with mainly glomerular lesions. Hypoxia-inducible factor (HIF)-1α is a transcriptional factor that induces genes supporting cell survival, but the involvement of HIF-1α in attenuating the progression of GN remains to be elucidated. We developed a new model of rat GN by coadministration of angiotensin II (AII) with Habu snake venom (HV) and investigated whether HIF-1α is involved in renal protection. Methods: Male Wistar rats were unilaterally nephrectomized on day 1, and divided into 4 groups on day 0; N group (no treatment), HV group, A group (AII), and H+A group (HV and AII). To preinduce HIF-1α, cobalt chloride (CoCl<sub>2</sub>) was injected twice before injections of HV and AII in 11 rats. Results: GN was detected only in the H+A group; observed first on day 2 and aggravated thereafter. HIF-1α was expressed in the glomeruli and renal tubules in the A and H+A groups. In the H+A group, GN was remarkably reduced by CoCl<sub>2</sub> pretreatment (44.9 to 12.2%, p < 0.01). Conclusion: Both HV and AII were critical for the development of GN, and HIF-1α remarkably attenuated the progression of GN.
