Abstract |
Background and purposes |
Through reducing immune response, VTCN1 could promote carcinoma indirectly. However, the direct effect of VTCN1 on carcinoma was not studied clearly, especially on ovarian carcinoma. In this paper, we verified the potential effect and mechanism of VTCN1 on ovarian carcinoma.
Methods |
The influence of high or low VTCN1 expression on the viability of ovarian cancer was detected by CKK-8 and annexin V-PI kit. The orthotopicxenograft tumor model was performed to evaluate the effect of VTCN1 on the promotion of tumor in vivo. Western blot was used to verify the signaling pathways predicted by bioinformatics analysis.
Results |
Low expression of VTCN1 could inhibit the viability and metastasis of ovarian carcinoma directly in vitro and vivo; Information analysis demonstrated that cell cycle and JAK2/STAT were involved in the regulation of VTCN1. The CDK2/4 and CDC25C expression and phosphorylation of JAK2/STAT had a direct relationship with the reduction of VTCN1.
Conclusions |
VTCN1 could affect the viability and metastasis of ovarian carcinoma by reducing the expression of CDK2/4 and CDC25C and phosphorylation of JAK2/STAT. It indicated that VTCN1 was a potential target for treating ovarian carcinoma.
