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

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)

Protein kinase C (PKC) modulates the function of the capsaicin receptor transient receptor potential vanilloid 1 (TRPV1). This modulation manifests as increased current when the channel is activated by capsaicin. In addition, studies have suggested that phosphorylation by PKC might

Neurotransmitter release from rat brain synaptosomes was measured following pretreatment with various phorbol esters. Ca2+-dependent, evoked neurotransmitter release was increased by phorbol esters that were active in stimulating protein kinase C. Protein kinase C activation was demonstrated by increased incorporation

B-chronic lymphocytic leukemia (B-CLL), the most common human leukemia, is characterized by predominantly non-dividing malignant mature CD5+ B lymphocytes with an apoptosis defect. Various microenvironmental stimuli confer a growth advantage on these leukemic cells and extend their survival in vivo.
