Effect of PDT on the activity of protein tyrosine kinase and phosphatase in H22 cells;

Effects and mechanisms of epidermal growth factor receptor of tyrosine kinase on cancer;

Expression, purification and bioactivity determination of epidermal growth factor receptor protein tyrosine kinase;

This paper reviewed recent progresses in the pharmacotherapeu- ties and clinical studies of the molecular-targeted anti-tumor drugs,including topoisomerase inhibitor, protein tyrosine kinase inhibitor,tumor angiogenesis inhibitor,PI3K-AKT-mTOR inhibitor and cyclin-de- pendent kinase inhib.

Objective To observe the changes of tyrosine kinase A(TrkA) in different cerebral regions of ovariectomized rats.

Objective To investigate the expression of tyrosine kinase A(TrkA) in cerebral cortex neural stem cells of embryonic rats,so to find the functions of TrkA and demonstrate the possible mechanism of neural stem cells directional differentiation during the development of the nervous system.

Objective To study the expressions of tyrosine kinase A (TrkA) and nerve growth factor (NGF) on cochlear corti in rats after whole cerebral ischemia-reperfusion.

The expression of NGF and TrkA mRNA/protein were measured with methods of RT-PCR and immunohistochemistry respectively at 2,4,6,12h and 24h after reperfusion in cerebral cortex ofrats.

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.
