Upregulation Of Fhit Gene Expression In Endometrial Carcinoma By Rna Activation

Endometrial carcinoma is the most common malignant tumors of the reproductive system, and fragile histidine triad (FHIT) plays an important role in multiple tumors. The purpose of this study was to investigate the expression of FHIT gene in endometrial carcinoma, and its effect on proliferation, invasion, and metastasis after upregulation. In vitro, the endometrial carcinoma cell lines were cultured. The FHIT-saRNA expression vector was constructed. The endometrial carcinoma cell line that upregulated the expression of FHIT was established, and whether the saRNA had a direct targeting regulation on the FHIT was verified. A difference of expression of FHIT in normal endometrial and endometrial carcinoma was detected. We detected the proliferation of endometrial carcinoma cell lines before and after activating FHIT. The endometrial carcinoma cell lines were compared with the corresponding transiently transfected cell lines in their capabilities of cell migration and invasion. The results showed that the expression of FHIT in endometrial carcinoma was significantly decreased or even deficient compared with normal endometrium. Upregulating the expression of FHIT is related to inhibiting the proliferation, invasion and metastasis of endometrial carcinoma. The possible mechanism is related to the regulation of cell cycle regulation, and plays a role in inhibiting tumor proliferation. The research on molecular mechanism in the development and progression of endometrial carcinoma has important theoretical significance for improving the diagnosis, treatment and prognosis of clinical tumors.
