Negative control for phorbol ester activation of protein kinase C.
There is substantial evidence that the tumor promoter 4 beta-12-O-tetradecanoylphorbol-13-acetate (TPA) elicits enhanced arachidonic acid release and its metabolism to prostaglandins and lipoxygenase products in many cell types. The goal of this study was to determine whether 4 alpha-12-O-tetradecanoylphorbol-13-acetate (4
Significant variability exists in the outcome of renal parenchymal inflammation following urinary tract infection (UTI) in childhood as some children experience renal parenchymal scarring (RPS) while others do not scar. Since TGF-beta1 is pro-fibrotic, we examined the role of this

4a alpha-Phorbol-9,9a-didecanoate, 4a alpha-phorbol-9-myristate-9a-acetate, and phorbol-9-myristate-9a-acetate-3-aldehyde were tested for skin tumor-promoting activity by using 7,12-dimethylbenz(a)anthracene as the initiating agent. There were 30 female ICR/Ha mice/group, and tests were continued for 434 to 461 days. 4a alpha-Phorbol-9,9a-didecanoate and 4a alpha-phorbol-9-myristate-9a-acetate were

Corpus luteum (CL) is a reproductive gland that plays a crucial endocrine role in the regulation of the estrous cycle, fertility, and pregnancy in cattle. The main function of CL is secretion of progesterone (P4), an important hormone for establishment

1. We investigated whether protein kinase C (PKC) activation stimulates Ca2+ entry in HEK 293 cells transfected with human TRPV4 cDNA and loaded with fura-2. 2. Phorbol 12-myristate 13-acetate (PMA), a PKC-activating phorbol ester, increased the intracellular Ca2+ concentration ([Ca2+]i)
