Colon cancer cell invasion is promoted by protein kinase CK2 through increase of endothelin-converting enzyme-1c protein stability.

Polycystic Ovary Syndrome (PCOS) is a gynecologic disorder with unsatisfactory treatment options. Hyperandrogenism and insulin resistance (IR) are two symptoms of PCOS. The majority of PCOS patients (approximately 50% to 70%) have IR and moderate diffuse inflammation of varying degrees. We investigated in-vitro and in-vivo effects of naringenin, morin and their combination on PCOS induced endometrial hyperplasia by interfering with the mTORC1 and mTORC2 signaling pathways. The vaginal smear test ensured the regular oestrous cycles in female rats. Serum cytokines (TNF-α and IL-6) were assessed using the ELISA test, followed by in-vivo and in-vitro determination of prominent gene expressions (mTORC1and C2, p62, LC3-II, and Caspase-3 involved in the inflammatory signaling mechanisms through RT-PCR, western bloting, or immunohistochemical analysis. In addition, the viability of naringenin or morin treated cells was determined using flow cytometry analysis. The abnormal oestrous cycle and vaginal keratosis indicated that PCOS was induced successfully. The recovery rate of the oestrous cycle with treatments was increased significantly (P<0.01) when compared to the PCOS model. Narigenin, morin, or a combination of the two drugs substantially decreased serum insulin, TNF-α, IL-6 levels with improved total anti-oxidant capacity and SOD levels (P<0.01). Treatments showed suppression of HEC-1-A cells proliferation with increased apoptosis (P<0.01) by the upregulation of Caspase-3 expression, followed by downregulation of mTORC, mTORC1, and p62 (P<0.01) expressions with improved LC3-II expressions (P<0.05) respectively. The histological findings showed a substantial increase in the thickness of granulose layers with improved corpora lutea and declined the number of cysts. Our findings noticed improved inflammatory and oxidative microenvironment of ovarian tissues in PCOS treated rats involving the autophagic and apoptotic mechanisms demonstrating synergistic in-vitro and in-vivo therapeutic effects of treatments on PCOS-induced endometrial hyperplasia.
