| Abstract: |
| High Trop2 expression relates to aggressive tumor behavior and contributes to poor overall survival rates in gastric cancer (GC) patients. However, little is known about the molecular mechanism of Trop2 in the carcinogenesis of GC. We found that over-expressed Trop2 induced cell proliferation and clone formation, inhibited cell apoptosis and induced S cell cycle arrest in GC cell lines, meanwhile, knockdown Trop2 inhibited cell proliferation and clone formation, induced cell apoptosis and inhibits S cell cycle arrest in vitro. Moreover, Trop2 depletion inhibited tumor growth , the anti-tumor rate in this report being 22.53% in vivo. In addition, Trop2 activated the PI3K/Akt signaling pathway to promote GC malignant progression. These results indicated that Trop2 is a critical regulation factor in the progression of GC, which may help to lead a novel insight into understanding the mechanism of the Trop2 in the pathogenesis of GC. |
