Figure Lengend Snippet: A Male C57BL/6 (8 weeks old) mice underwent ischemic injury (renal pedicle clamping, 35 min, both kidneys, Bi-IRI)), and the Mcl-1 inhibitor ( S63845 ) was given 6 h later and daily for the next 5 days via intravenous injection at a dose of 5 mg/kg. The mice were sacrificed 3 weeks later. Mcl-1 inhibition accelerated functional recovery, indicated by: B rapid BUN decline ( n = 9 and 10), C preserved GFR ( n = 8) and attenuation of the development of kidney fibrosis, indicated by: D lower mRNA levels ( n = 6 and 9) and E protein levels ( n = 7) of profibrotic and fibrotic components as well as F quantitative Picrosirius red staining ( n = 6) ( F ). Scale bar=100 μm. Data are means ± SEM, * P < 0.05, ** P < 0.01, *** P < 0.001, analyzed using 2 tailed Student’s t test for all.
Article Snippet: The Mcl-1 inhibitor S63845 (MedChemExpress) was formulated and protected from light in 2% Vitamin E/TPGS (Sigma) in NaCl 0.9% (w/v) and was delivered to wild-type C57BL/6 mice by retro-orbital injection for 2 days prior to, and on the day of surgery for acute experiments.
