Objective To detect normal rat jejunum epithelial cells to learn about the distribution of peptide YY(PYY)receptor and measured two important parameters of PYY receptor so as to explore the target that PYY binds to and display its physiological function.

Effect of peptide YY on subcutaneous transplantation tumor of human hepatoma in nude mice;

Expression and its clinical significance of receptor tyrosine kinase EphB1 in gastric carcinoma

Mer is one member of Axl receptor tyrosine kinase family, and its ligand Gas6 can stimulate activity of Mer receptor tyrosine kinase after binding it, and then activate the downstream signal transduction pathway, Mer participates in cell inflammation, apoptosis, tumorigenesis, thrombosis and hemostasis.

FLT3,a member of receptor tyrosine kinase III family,is primarily expressed by hematopoietic cells and plays a significant role in hematopoiesis and leukemogenesis.

Modulation of potassium channels by receptor tyrosine kinases:recent progress;

The epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases have close connection with the initiation, progression and progn osis of various malignancies.

Receptor tyrosine kinase (RTK) inhibitors targeting VEGF receptor is one of the most promising agents.

Our study is aimed to investigate whether EphA3,which is a member of RTK family,can play a role in PCa progression and whether it can promote the transition of PCa from androgen dependent stage to androgen independent stage as well as the mechanism of its function.
