OBJECTIVE: The study aimed to evaluate the feasibility and reproducibility of measuring phospholipase C zeta (PLCζ) using immunostaining in human sperm and to investigate the relationship between PLCζ immunoreactivity and DNA fragmentation and oxidation in human sperm. METHODS: Semen samples were obtained from participants (n=44) and processed by the conventional swim-up method. Sperm concentration, motility, normal form by strict morphology, DNA fragmentation index assessed by terminal deoxynucleotidyl transferase dUTP nick end labeling method and immunofluorescent expression for 8-hydroxy-2'-deoxyguanosine (8-OHdG) and PLCζ were assessed...

Protein kinase C (PKC) isoforms differentially regulate platelet functional responses downstream of glycoprotein VI (GPVI) signaling, but the role of PKCs regulating upstream effectors such as Syk is not known. We investigated the role of PKC on Syk tyrosine phosphorylation using the pan-PKC inhibitor GF109203X (GFX). GPVI-mediated phosphorylation on Syk Tyr-323, Tyr-352, and Tyr-525/526 was rapidly dephosphorylated, but GFX treatment inhibited this dephosphorylation on Tyr-525/526 in human platelets but not in wild type murine platelets...

Endothelial cells expressing fibroblast growth factor receptor-1 (FGFR-1) migrate and proliferate in response to treatment with FGF. We analysed ligand-induced migration and proliferation of porcine aortic endothelial cells expressing wild-type FGFR-1, point-mutated Y766F FGFR-1, unable to activate phospholipase C-gamma1 (PLC-gamma1), or carboxyl-terminally truncated FGFR-1, lacking either 48 (from amino acid 774 in the FGFR-1 sequence) or 63 (from amino acid 759) amino acid residues of the C-terminal tail...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
