Purpose: To investigate the influence of miR-21 down-regulation on cell proliferation, apoptosis, invasion and migration of ovarian papillary adenocarcinoma cell lines (OVCAR3). Methods: Short-hairpin RNA (shRNA), specifically targeting miR-21, was constructed and transfected into OVCAR3 cells using the pSIREN-RetroQ linear vector (pSIREN-miR-21). The expression of miR-21 was detected with stem-loop real-time RT-PCR in OVCAR3 cells. Cell proliferation and apoptosis were monitored using the MTT assay and flow cytometry, respectively. Cell migration and invasion were assessed using the transwell migration and scratch-wound assay, respectively. Western-bloting was used for PDCD4 protein expression. Results: pSIREN-miR-21 suppressed miR-21 expression in OVCAR3 cells. miR-21 expression levels in pSIREN-miR-21 cells was 0.3 ± 0.1, which was significantly lower when compared with pSIREN-miR-21-Neg and control groups (P < 0.01). Cell inhibition rate in the pSIREN-miR-21 group was higher than the control group (29.4% vs 9.0%, P < 0.01), as was the percentage of apoptotic and necrotic cells. By transwell migration assay, the number of cells migrating in the pSIREN-miR-21 group was significantly lower than in the control group. In addition, fewer cells were observed in the wounded area of the pSIREN-miR-21 group following the scratch-wound assay. PDCD4 expression was increased in OVCAR-3 cells transfected by pSIREN-miR-21 compared with vector-control transfected cells. Moreover, the optical density of the transfected cells was significantly lower than the two control groups.

: Diabetes and breast cancer are pathophysiologically similar and clinically established diseases that co-exist with a wider complex similar molecular signalling and having similar set of risk factors. Insulin plays a pivotal role for invasion and migration of breast cancer cells. Several ethnopharmacological evidences light the concomitant anti-diabetic and anti-cancer activity of medicinal plant and phytochemicals against breast tumor of patients with diabetes. This present article reviewed the findings on medicinal plants and phytochemicals with concomitant anti-diabetic and anti-cancer effects reported in scientific literature to facilitate the development of dual-acting therapies against diabetes and breast cancer. The schematic tabular form of published literatures on medicinal plants (63 plants belongs to 45 families) concluded the dynamics of phytochemicals against diabetes and breast tumor that could be explored further for the discovery of therapies for controlling of breast cancer cell invasion and migration in patient with diabetes.

Abstract Background MCM3AP-AS1 is a recently characterized lncRNA playing an oncogenic role in several cancers. However, its role in lung cancer remains unknown. Here, we aimed to explore the functions of MCM3AP-AS1 in small cell lung cancer (SCLC) and the possible underlying mechanisms. Methods MCM3AP-AS1 and ROCK1 levels in SCLC patients were analyzed by qPCR. RNA pull-down and luciferase assays were performed to analyze the interaction between MCM3AP-AS1 and miR-148a. ROCK1 mRNA and protein levels were detected by qPCR and Western blot, respectively. Cell invasion and migration were analyzed by Transwell assays. Results MCM3AP-AS1 was upregulated in patients with SCLC, and a high MCM3AP-AS1 level was accompanied by a low survival rate. The binding of MCM3AP-AS1 to miR-148a predicted by bioinformatics analysis was verified by RNA pull-down and luciferase assays. However, MCM3AP-AS1 and miR-148a did not affect each other’s expression. ROCK1 was upregulated in SCLC tissues and positively correlated with MCM3AP-AS1. In SCLC cells, MCM3AP-AS1 overexpression increased ROCK1 and promoted cancer cell invasion and migration, while miR-148a overexpression showed the opposite effects and attenuated the effects of MCM3AP-AS1 overexpression on ROCK1 expression and cell behaviors. Conclusions MCM3AP-AS1 sponges miR-148a, thereby increasing SCLC cell invasion and migration via upregulating ROCK1 expression.

Objective: We aimed to investigate the mechanism of the regulatory axis of miR-196b/AQP4 underlying the invasion and migration of lung adenocarcinoma (LUAD) cells. Methods: LUAD miRNA and mRNA expression profiles were downloaded from TCGA database and then differential analysis was used to identify the target miRNA. Target gene for the miRNA was obtained via prediction using 3 bioinformatics databases and intersection with the differentially expressed mRNAs searched from TCGA-LUAD. Then, qRT-PCR and western blot were used to validate the expression of miR-196b and AQP4. Dual-luciferase reporter assay was performed to confirm the targeting relationship between miR-196b and AQP4. Transwell assay was used to investigate the migration and invasion of LUAD cells. Results: MiR-196b was screened out by differential and survival analyses, and the downstream target gene AQP4 was identified. In LUAD, miR-196b was highly expressed while AQP4 was poorly expressed. Besides, overexpression of miR-196b promoted cell invasion and migration, while overexpression of AQP4 had negative effects. Moreover, the results of the dual-luciferase reporter assay suggested that AQP4 was a direct target of miR-196b. In addition, we also found that overexpressing AQP4 could suppress the promotive effect of miR-196b on cancer cell invasion and migration. Conclusion: MiR-196b promotes the invasion and migration of LUAD cells by down-regulating AQP4, which helps us find new molecular targeted therapies for LUAD.
