Abstract Objectives: The antitumor effects of pyropheophorbide-α methyl ester-mediated photodynamic therapy (MPPa-PDT) were observed in several cancers. The objective of this investigation was to examine the antineoplastic efficacy of MPPa-PDT acting on lung carcinoma A549 cells and further elaborate mechanisms. Methods: The viability of A549 cells was examined with cell counting kit-8 after MPPa-PDT disposal. Hoechst 33342 staining, monodansylcadaverine (MDC) staining, and transmission electron microscopy were employed to observe apoptotic bodies and autophagic vesicles. Flow cytometry with Annexin V/propidium iodide (PI) labeling objectively assessed cell death. The expression of associated proteins, including Caspase-3, Beclin-1, LC-3II, and More > Graphic Abstract

Abstract This study intended to investigate the effects of miR-3188 on breast cancer and to reveal the possible molecular mechanisms. miR-3188 was upregulated and TUSC5 was downregulated in breast cancer tissues and MCF-7 cells compared to normal tissue and MCF-10 cells. After MCF-7 cells were transfected with miR-3188 inhibitor, cell proliferation and migration were inhibited, whereas apoptosis was promoted. Luciferase reporter assay suggested that TUSC5 was a target gene of miR-3188. In addition, miR-3188 overexpression increased the p-p38 expression, while miR-3188 suppression decreased the p-p38 expression significantly. miR-3188 regulated breast cancer progression via the p38 MAPK More >

Abstract Current mainstream pharmacological options for the treatment of endocrine-resistant breast cancer have limitations in terms of their side effect profile and lack of discrimination between normal and cancer cells. In the current study, we assessed the responses of normal breast epithelial cells MCF10A, estrogen receptorpositive (ER+ ) MCF-7, and ER-silenced pII breast cancer cells to inhibitors (either individually or in combination) of downstream signaling molecules. The expression/activity of ERK1/2, p38 MAPK, and Akt was determined by Western blotting. Cell proliferation, motility, and invasion were determined using MTT, wound healing, and Matrigel assays, respectively. Morphological changes… More >
