Propofol Inhibits Lung Cancer A549 Cell Growth and Epithelial–Mesenchymal Transition Process by Upregulation of MicroRNA-1284

Propofol has been widely used in lung cancer resections. Some studies have demonstrated that the effects of propofol might be mediated by microRNAs (miRNAs). This study aimed to investigate the effects and mechanisms of propofol on lung cancer cells by regulation of miR-1284. A549 cells were treated with different concentrations of propofol, while transfected with miR-1284 inhibitor, si-FOXM1, and their negative controls. Cell viability, migration, and invasion, and the expression of miR-1284, FOXM1, and epithelial–mesenchymal transition (EMT) factors were detected by CCK-8, Transwell, qRT-PCR, and Western blot assays, respectively. In addition, the regulatory and binding relationships among propofol, miR-1284, and FOXM1 were assessed, respectively. Results showed that propofol suppressed A549 cell viability, migration, and invasion, upregulated E-cadherin, and downregulated N-cadherin, vimentin, and Snail expressions. Moreover, propofol significantly promoted the expression of miR-1284. miR-1284 suppression abolished propofol-induced decreases of cell viability, migration, and invasion, and increased FOXM1 expression and the luciferase activity of FOXM1-wt. Further, miR-1284 negatively regulated FOXM1 expression. FOXM1 knockdown reduced cell viability, migration, and invasion by propofol treatment plus miR-1284 suppression. In conclusion, our study indicated that propofol could inhibit cell viability, migration, invasion, and the EMT process in lung cancer cells by regulation of miR-1284.

(-)-Epigallocatechin-3-Gallate Induces Apoptosis and Inhibits Invasion and Migration of Human Cervical Cancer Cells

Invasion and metastasis are the major causes of cancer-related death. Pharmacological or therapeuticinterventions such as chemoprevention of the progression stages of neoplastic development could result insubstantial reduction in the incidence of cancer mortality. (-)-Epigallocatechin-3-gallate (EGCG), a promisingchemopreventive agent, has attracted extensive interest for cancer therapy utilizing its antioxidant, antiproliferativeand inhibitory effects on angiogenesis and tumor cell invasion. In this study, we assessed theinfluence of EGCG on the proliferative potential of HeLa cells by cell viability assay and authenticated theresults by nuclear morphological examination, DNA laddering assay and cell cycle analysis. Further we analyzedthe anti-invasive properties of EGCG by wound migration assay and gene expression of MMP-9 and TIMP-1in HeLa cells. Our results indicated that EGCG induced growth inhibition of HeLa cells in a dose- and timedependentmanner. It was observed that cell death mediated by EGCG was through apoptosis. Interestingly,EGCG effectively inhibited invasion and migration of HeLa cells and modulated the expression of related genes(MMP-9 and TIMP-1) . These results indicate that EGCG may effectively suppress promotion and progressionstages of cervical cancer development.     

Propofol induces proliferation and invasion of gallbladder cancer cells through activation of Nrf2

ABSTRACT: BACKGROUND: Propofol is one of the most commonly used intravenous anaesthetic agents during cancer resection surgery, but the effect of propofol on gallbladder cancer is not clear. NF-E2-related factor 2 (Nrf2) is abundantly expressed in cancer cells and relates to proliferation, invasion, and chemoresistance. The aims of the current study were to evaluate effects of propofol on the behavior of human GC cells and role of Nrf2 in these effects. METHOD: The effects of propofol on cell proliferation, apoptosis, and invasion were detected by MTT assays, flow cytometry, and transwell assay. Also, activation of Nrf2 was determined by western blot, RT-PCR, and immunofluorescence assays. Nrf2 was knocked-down in GBC-SD cells by shRNA before evaluating the role of Nrf2 in the influence of propofol on biological behaviors. RESULTS: Propofol inhibited the proliferation of GBC-SD cells in a dose- and time- dependent manner. After exposure to propofol for 48 h, GBC-SD cells showed decreased apoptosis and increased invasion. Also, propofol over-expressed Nrf2 at both the protein and mRNA levels and induced translocation of Nrf2 into the nucleus. Finally, loss of Nrf2 by shRNA reversed the effect of propofol on cell proliferation, apoptosis, and invasion. CONCLUSION: Propofol induces proliferation and promotes invasion of GC cells through activation of Nrf2.

Inotodiol Inhabits Proliferation and Induces Apoptosis through Modulating Expression of cyclinE,p27, bcl-2, and bax in Human Cervical Cancer HeLa Cells

Inonotus obliquus is a medicinal mushroom that has been used as an effective agent to treat various diseasessuch as diabetes, tuberculosis and cancer. Inotodiol, an included triterpenoid shows significant anti-tumor effect.However, the mechanisms have not been well documented. In this study, we aimed to explore the effect of inotodiolon proliferation and apoptosis in human cervical cancer HeLa cells and investigated the underlying molecularmechanisms. HeLa cells were treated with different concentrations of inotodiol. The MTT assay was used toevaluate cell proliferating ability, flow cytometry (FCM) was employed for cell cycle analysis and cell apoptosis,while expression of cyclinE, p27, bcl-2 and bax was detected by immunocytochemistry. Proliferation of HeLacells was inhibited by inotodiolin a dose-dependent manner at 24h (r=0.9999, p<0.01). A sub-G1 peak (apoptoticcells) of HeLa cells was detected after treatment and the apoptosis rate with the concentration and longerincubation time (r=1.0, p<0.01), while the percentage of cells in S phase and G2/M phase decreased significantly.Immunocytochemistry assay showed that the expression of cyclin E and bcl-2 in the treated cells significantlydecreased, while the expression of p27 and bax obviously increased, compared with the control group (p<0.05).The results of our research indicate that inotodiol isolated from Inonotus obliquus inhibited the proliferationof HeLa cells and induced apoptosis in vitro. The mechanisms may be related to promoting apoptosis throughincreasing the expression of bax and cutting bcl-2 and affecting the cell cycle by down-regulation the expressionof cyclin E and up-regulation of p27. The results further indicate the potential value of inotodiol for treatmentof human cervical cancer.
