Synthesis Pyrano [2,3-c] Pyrazole-based compounds to induce apoptosis by reducing the expression of anti-apoptotic Bcl-2 protein in human breast cancer MCF-7 cells

Change in the Expression of BAK، FAS، BAX، TNF-A، BCL-2 and Survivin Apoptosis Genes of the Human Breast Adenocarcinoma Cells (MCF-7) by Staphylococcal Enterotoxin B

Introduction: Breast cancer is one of the most prevalent malignancies among women. Patients whose suffering from this condition, as a result of the use of conventional therapies often have a poor response to treatment and the relapse among them is frequent. In this study, the effects of staphylococcal enterotoxin type B on BAK، FAS، BAX، TNF-a، BCL-2 و Survivin genes expression in human breast ...

Expression and anti-apoptotic function of TRAF4 in human breast cancer MCF-7 cells

Tumor necrosis factor (TNF) receptor-associated factor 4 (TRAF4) was initially identified as a gene amplified and overexpressed in breast carcinoma. The present study investigated the expression and anti-apoptotic function of TRAF4 in human breast cancer MCF-7 cells. TRAF4 was found to be localized in the cytoplasm and nuclei of MCF-7 cells by immunofluorescence staining and western blotting. T...

Effect of rosemary essential oil on the expression of BCL-XL, an anti-apoptotic gene, in MCF-7 cell line breast cancer

Overexpression of HER2 modulates bcl-2, bcl-XL, and tamoxifen-induced apoptosis in human MCF-7 breast cancer cells.

Overexpression of HER2 in estrogen receptor (ER)-positive human breast tumors has been associated with resistance to endocrine therapy. Here we investigated the effects of HER2 on expression of apoptotic pathways and modulation of tamoxifen-induced apoptosis in ER-positive MCF-7 breast cancer cells. We report that HER2 overexpression in MCF-7 cells is accompanied by up-regulation of antiapoptot...

Effects of combined 5-Fluorouracil and ZnO NPs on human breast cancer MCF-7 Cells: P53 gene expression, Bcl-2 signaling pathway, and invasion activity

Objective(s): The significant contribution of nanoparticles to cancer treatment has attracted therapeutic attention. The present study aimed to evaluate the synergistic effects of 5-fluorouracil (5-FU) and zinc oxide nanoparticles (ZnO NPs) as multimodal drug delivery on human breast cancer MCF-7 cells.Materials and Methods: In this in-vitro study, the impact of 5-FU and ZnO NPs in the sin...

Stimulatory Effect of Indolic Hormone on As2O3 Cytotoxicity in Breast Cancer Cells: NF-κB-dependent Mechanism of Action of Melatonin

The advent of combination therapy unprecedentedly shifted the paradigm of cancer treatment by reconstructing the conventional protocols. By identifying the anti-tumoral activity for different natural products, recent interest has focused on inventing the combined-modality strategies in order to increase the cure rates of cancer, while reducing the toxic side effects of current intensive regimen...
