Relationship between tyrosine protein kinase and synapse plasticity, learning and memory;

· AIM: To study the function of tyrosine protein kinase pathway in ultraviolet induced enhanced PGE2 synthesis in human lens epithelial cells (HLECs).

Objective: To examine the effect of basic fibroblast growth factor (bFGF) of different concentrations on activitites of tyrosine protein kinase (TPK), protein kinase C(PKC) and extracellular signal regulated protein kinase (ERK) in NIH3T3 cell line and to elucidate the signal pathway in cell proliferation and differentiation.

Protein kinase C and protein tyrosine kinase mediate lipopolysaccharide-and cytokine-induced nitric oxide formation in vascular smooth muscle cells of rats;

Effects of Dexamethasone and protein tyrosine kinase inhibitor on tumour necrosis factor alpha and interleukin 1 beta induced IL-8 production from gastric epithelial cell;

After 24 h,48 h,72 h and 96 h, the OECs been captured, and the activity of protein tyrosine kinase(PTK) was examined by.

Protein tyrosine kinases (PTKs) are the family members of oncoproteins and protooncoproteins which play important roles in the normal proliferation and unusual hyperplasia course.
