In addition, the phosphorylation level of STAT3 decreased after the administration of metformin or/and 4SC-202. Furthermore, inhibition of STAT3 by S31-201 suppressed the expression of TWIST1 and led to a decline in migration and invasion of OSCC, while overexpression of TWIST1 attenuated these effects.

Metformin and 4SC-202 suppressed the invasion and migration of OSCC through inhibition of STAT3/TWIST1, and this scheme can serve as a novel therapeutic strategy for OSCC.

Mounting evidence has demonstrated that circular RNAs (circRNAs) play indispensable roles in the progression of bladder cancer. Public database mining showed that hsa_circRNA_100146 (circRNA_100146) was highly expressed in bladder cancer. This study aimed to characterize the biological role of circRNA_100146 and clarify the underlying mechanism in bladder cancer.

We evaluated the relationship between circRNA_100146 expression and clinicopathological features. Furthermore, gain- and loss-of-function studies were conducted in bladder cancer cells via transfection with gene-carrying plasmids (over-expression) or specific short hairpin RNAs (knockdown). Moreover, computational algorithms and dual-luciferase reporter assays were performed to explore the possible mechanisms of action. Additionally, in vivo xenograft experiments were performed to further analyze the effect of circRNA_100146 on tumor growth.

Our data showed that circRNA_100146 expression was increased in bladder cancer tissues and cell lines, ar progression by regulating RNF2 expression and that circRNA_100146 may serve as a novel biomarker in human bladder cancer.
Zeaxanthin, a carotenoid commonly found in plants, has a variety of biological functions including anti-cancer activity.

This study aimed to investigate the potential mechanisms of zeaxanthin in human gastric cancer cells.

CCK-8 assay was used to examine the cytotoxic effect of zeaxanthin on human gastric cancer cells. Flow cytometry was used to analyse AGS cell cycle distribution and apoptosis status. Western blot analysis was used to detect the expression levels of cycle-related proteins (Cyclin A, Cyclin B1, CDK1/2, p21, and p27), apoptosis-related proteins (Bcl-2, Bad, caspase-3, PARP), MAPK, AKT, STAT3, and NF-κB.

CCK-8 assay showed that zeaxanthin has obvious cytotoxic effects on 12 types of human gastric cancer cells, but no obvious toxic effect on normal cells. In addition, flow cytometry and Western blotting results showed that zeaxanthin induces apoptosis by reducing mitochondrial membrane potential; increasing Cytochrome C, Bax, cleaved-caspase-3 (cle-cas-3), and cleaved-PARP (cle-PARP) expmediated MAPK, AKT, NF-κB, and STAT3 signaling pathways, and it is expected to become a new drug for the treatment of human gastric cancer.
miR-214 has been reported to contribute to erlotinib resistance in non-small-cell lung cancer (NSCLC) through targeting LHX6; however, the molecular mechanisms underlying the involvement of LHX6 in mediating the resistance to EGFR-TKIs in erlotinib-resistant NSCLC HCC827 (HCC827/ER) cells remain unknown. This study aimed to investigate the mechanisms responsible for the contribution of LHX6 to EGFR-TKIs resistance in HCC827/ER cells.

HCC827/ER cells were generated by erlotinib treatment at a dose-escalation scheme. LHX6 knockout or overexpression was modeled in HCC827 and HCC827/ER cells, and then erlotinib IC
values were measured. The cell migration ability was evaluated using a transwell migration assay, and the TCF/LEF luciferase activity was assessed with a TCF/LEF reporter luciferase assay. LHX6, β-catenin and Cyclin D1 expression was quantified using qPCR and Western blotting assays. In addition, the LHX6 expression was detected in lung cancer and peri-cancer specimens using immunohistochemical stt/β-catenin pathway.
LHX6 down-regulation may induce EGFR-TKIs resistance and increase the migration ability of HCC827/ER cells via activation of the Wnt/β-catenin pathway.
An important issue with compounds for treating ovarian cancer is the development of drug resistance and side effects. Butorphanol is a synthetic opioid. Geldanamycin Antineoplastic and Immunosuppressive Antibiotics inhibitor Opioids have been shown to promote or prevent tumor growth and metastasis. This research aimed to reveal the affection of Butorphanol on the malignant biological behaviors of ovarian cancer cells.

Different concentrations of Butorphanol were used to treat ovarian cancer cell lines, ES-2 and SKOV3. Biological functions of cells were performed by CCK-8 assay, colony formation assay, apoptosis analysis, transwell assays and scratch assays. The differences in the transcriptome of the Butorphanol treated and negative control (NC) cells were analyzed by RNA-Seq.

Butorphanol treatment significantly inhibited the viability, colony-forming, migration and invasion of ES-2 and SKOV3 cells compared to NC. Furthermore, Butorphanol treatment obviously induced the apoptosis of ES-2 and SKOV3 cells and regulated the expression of apoptosis-related proteins. Additionally, Butorphanol treatment significantly reduced the expression of p-AKT, p-mTOR and P70S6K without affecting the expression of AKT and mTOR in ES-2 and SKOV3 cells. Forty-four genes were identified to up-regulate its expression, while 17 genes were identified to down-regulate its expression in Butorphanol-treated cells. Among them, TMEFF1 was found to be significantly down-regulated in Butorphanol-treated cells. Additionally, the restoration of TMEFF1 expression complemented the inhibitory effect of Butorphanol treatment on cell proliferation and invasion.

In conclusion, Butorphanol is a compound with potential to treat ovarian cancer. TMEFF1 may play a key role in inhibiting the malignant proliferation and metastasis of Butorphanol treatment on ovarian cancer cells.
