Dataset link Influence of retinol on kidney in 5/6 nephrectomy mice

Experimental Protocol


Differential gene expression between retinol (-) feeding and clock mutant in 5/6 nephrectomized mouse was measured on the kidney at 8 weeks after operation. Four-week-old male ICR mice (Charles River Japan, Inc., Yokohama, Japan) were housed in a light-controlled room (lights on from Zeitgeber time [ZT] 0 to ZT12) at 24 ± 1°C and 60 ± 10% humidity, with food and water available ad libitum. Mice were synchronized to the lighting conditions for 2 weeks before surgery. Male ICR mice (5 weeks old) were purchased from Charles River Japan, Inc. (Kanagawa, Japan). Clock mutant mice (C57BL/6J-ClockmlJt/J) were purchased from The Jackson Laboratory (Bar Harbor, ME, USA). We placed them in the ICR genetic background to enhance breeding robustness and care of the young. These mice were backcrossed using a Jcl:ICR background for more than eight generations. We prepared mouse models of CRF by 5/6Nx operation (Ope) under sodium pentobarbital (40 mg/kg, i.p.) or diethyl ether anesthesia. 5/6Nx was performed in two stages. In the first surgical procedure (at 6 weeks of age), two-thirds of the left kidney was removed by cutting off both poles. Seven days later, the right kidney was completely removed. After the operation, mice were housed for 8 weeks (until they were 16 weeks old) in order to achieve CRF. Sham-operated (Sham) mice were subjected to laparotomy on the same days as the procedure in the 5/6Nx mice. This method was also used for treating Clk/Clk mice. Retinol-free food (A minus) was purchased form KBT ORIENTAL CO., LTD. To investigate the influences of retinol-free feeding on kidney, mice were fed from the fourth week to the eighth week after an operation.
