Transient Receptor Potential Channel 6 Knockout Ameliorates Kidney Fibrosis by Inhibition of Epithelial-Mesenchymal Transition.

Kidney fibrosis is generally confirmed to have a significant role in chronic kidney disease, resulting in end-stage kidney failure. Epithelial-mesenchymal transition (EMT) is an important molecular mechanism contributing to fibrosis. Tubular epithelial cells (TEC), the major component of kidney parenchyma, are vulnerable to different types of injuries and are a significant source of myofibroblast by EMT.

New clinical information and physician prescribing: How do pediatric labeling changes affect prescribing to children?

Our study examines how physician prescribing responds to new scientific information added to drug labels. We focus on a series of label changes with new information about the effects of drugs in children. The information arose in response to a 1997 policy, pediatric exclusivity, which gave drug sponsors a 6-month exclusivity extension for conducting additional pediatric studies of already marketed drugs.

Functional coupling between BKCa and SOC channels.

High-conductance, voltage- and calcium-activated potassium channels (BKCa) and store-operated calcium channels (SOCs) are belong to K channels superfamily and calcium channels superfamily respectively. Since BKCa potassium channels can be activated by calcium ions, we set out to examine whether SOCs are coupled with BKCa and to probe the relationship of BKCa and SOCs. First, we proved that BKCa immunoprecipitated with Orai1, and confocal microscopy showed that BKCa co-localized with Orai1.

Facile mechanical shaking method is an improved isolation approach for islet preparation and transplantation.

Successful islet isolation is crucial for islet transplantation and cell treatment for type 1 diabetes. Current isolation methods are able to obtain 500-1,000 islets per rat, which results in a waste of ≥50% of total islets. In the present study, a facile mechanical shaking method for improving islet yield (up to 1,500 per rat) was developed and summarized, which was demonstrated to be more effective than the existing well-established stationary method.
