ABSTRACT
Store operated calcium channels (SOCCs) have been suggested to play a critical role in many diabetic complications. Diabetic cystopathy (DCP) is common in patients with diabetes, but the role of SOCCs in DCP is still unclear. The aim of the present study was to investigate the role of SOCCs in DCP with streptozocin (STZ)induced diabetic rats. Specifically, the authors investigated whether SOCCs were altered in streptozocin (STZ)induced diabetic rats and, if so, how this may contribute to the contraction of bladder detrusor strips and the intracellular Ca2+ concentration of bladder smooth muscle cells in diabetic rats. Cyclopiazonic acid (CPA, 10 µM) and SKF96365 (10 µM) were used to activate and inhibit SOCCs respectively, to research the effects of SOCCs on the contraction of the bladder detrusor strips in normal and STZinduced diabetic rats at the 4th, 8th and 12th week after the diabetic rat model was established. The changes of intracellular Ca2+ were also evaluated under confocal microscopy with pretreated Fluo4AM. In addition, the expressions of Orai1 and STIM1 were detected by reverse transcriptionquantitative polymerase chain reaction and western blotting at different time points. According to the results, the contractive frequency of diabetic bladder muscle strips was higher than that of controls in the 4th and 8th week. The increased fluorescence intensity was detected after using CPA and SKF96365 in diabetic groups. The expressions of Orai1 and STIM1 changed in a timedependent manner.
