Objective Aberrant expression of microRNAs is a key regulator of tumorigenesis and progression in endometrial cancer. We assessed the effect of microRNA-29b (miR-29b) on proliferation, chemosensitivity, migration, and invasion of endometrial cancer cells. Methods The proliferation of endometrial cancer cells was examined by water-soluble tetrazolium (WST)-1 assay. The effects of miR-29b on migration and invasion were evaluated by transwell migration and Matrigel invasion assays. Western blotting was used to assess protein expression levels after altered expression of miR-29b. The effect of miR-29b on cisplatin-induced apoptosis was examined by Caspase-Glo 3/7 assay. Results miR-29b inhibited proliferation and decreased migration and invasion of endometrial cancer cells. It also enhanced the sensitivity of endometrial cancer cells to cisplatin and increased cisplatin-induced apoptosis by regulating expression of BAX and Bcl-2. Moreover, miR-29b changed the expression level of phosphatase and tensin homolog (PTEN) and p-AKT by directly binding to the 3′ untranslated region of PTEN. Conclusion miR-29b played important roles in proliferation and progression in endometrial cancer cells by direct regulation of PTEN. It might be used as a biomarker to predict chemotherapy response and prognosis in endometrial cancer.

IntroductionDocosahexaenoic acid (DHA) supplementation has been reported to negatively correlate with cancer cell proliferation and tumour development in many cancer types. Although cumulative evidence has demonstrated the apoptotic effect and cytotoxicity of DHA against tumour development in many cell types, the precise cellular and biochemical mechanisms of DHA-induced apoptosis in human endometrial cancer cells have not been investigated.Material and methodsMTT assay was performed to confirm the degree of apoptosis by combining treatment with DHA and triacsin C in endometrial cancer cell line. The synergistic effects of triacsin C and DHA were identified by performing flowcytometry and immunoblotting analysis.ResultsCombined treatment with DHA and triacsin C significantly induced apoptosis in RL95-2 endometrial carcinoma cells. Combined treatment with 125 μM DHA and 5 μM triacsin C significantly increased the sub-G1 population and apoptotic fragments in endometrial carcinoma cells. It was also demonstrated that DHA and triacsin C induced apoptosis through mitochondrial pathways via caspases-9, -3, and -7 as well as through the extrinsic pathway by activation of caspase-8/BID.ConclusionsFurther elucidation of the apoptotic mechanisms involving DHA treatment with ACS ablation could shed light on possible new treatment strategies for endometrial cancer. In addition, further research into the mechanisms of DHA and triacsin C-induced apoptotic mechanisms may lead to the development of therapeutic strategies for endometrial cancer.

This study aimed to assess the effects of the antidiabetic drug Exendin-4 (Exe-4), a GLP-1 receptor agonist, on the response of human endometrial cancer cells to chemotherapy under high glucose (HG) conditions. Cell viability was detected using a cell counting kit (CCK)-8. Cell apoptosis and reactive oxygen species (ROS) levels were measured by flow cytometry. Gene expression was evaluated by real-time PCR and immunoblotting. The chemotherapeutic drug cisplatin (DDP) dose-dependently inhibited both human endometrial adenocarcinoma Ishikawa and HEC1B cells, a response reversed by HG. Meanwhile, Exe-4 attenuated hyperglycemia’s effect by elevating intracellular lactate dehydrogenase (LDH) and ROS production. Similarly, DDP-induced elevation of intracellular rhodamine123 was attenuated by HG, and Exe-4 reversed HG’s impact. The chemoresistance genes multidrug resistance-associated protein 1 (MRP1) and P-glycoprotein (Pgp) were upregulated. At the same time, topoisomerase II (TOPO II) was downregulated under HG conditions, suggesting HG-induced chemoresistance. Exe-4 did not significantly influence the above genes. DDP downregulated Bcl-2 and Bcl-XL and upregulated Bax, cytosolic cytochrome c, and PARP under normal glucose (NG) versus HG conditions, and Exe-4 attenuated these effects. Upstream of Bax/Bcl, acetylated P53 was upregulated by DDP and downregulated by HG, whose effect was reversed by Exe-4. DPP treatment significantly induced apoptosis and cell cycle arrest in the S phase under NG, and HG reduced these effects. Prolonged exposure to HG induces DDP chemoresistance in human endometrial cancer cells but is alleviated by Exe-4.
