VEGF Signaling Promotes Cell Growth and Metastasis in Extrahepatic Cholangiocarcinoma in a VEGF Receptor Mediated Pathway (ECC) — VEGF ECC

Extrahepatic Cholangiocarcinoma Clinical Trial

Official title:
VEGF Signaling Promotes Cell Growth and Metastasis in Extrahepatic Cholangiocarcinoma in a VEGF Receptor Mediated Pathway

Status Active, not recruiting

Clinical Trial Summary

The investigators study the VEGF signaling in ECC cell lines,patients and its mechanism in ECC growth, proliferation and apoptosis.

Clinical Trial Description

Several studies have documented the elevated expression of VEGF, VEGFR1 and VEGFR2 in cancer cell lines. Another study observed a sequential elevation of VEGF in low-grade dysplasia, high-grade dysplasia and early stage liver cancer. Clinical analyses have discovered the high expression of VEGF is correlated with tumor progression, vascular invasion, distal metastasis and poor prognosis. However, few studies have been conducted to investigate the VEGF signaling in ECC cells and its possible mechanism in regulating ECC growth.Therefore,we try to clarify the mechanism of VEGF signal in ECC growth,proliferation and apoptosis. ;
