objective: hypoxia-inducible factor (hif)-1 plays an essential role in the body’s response to low oxygen concentrations and regulates expression of several genes implicated in homeostasis, vascularization, anaerobic metabolism as well as immunological responses. increased levels of hif-1α are associated with increased proliferation and more aggressive breast tumor development. lactobacilli have...

ChIP-seq has been commonly applied to identify genomic occupation of transcription factors (TFs) in a context-specific manner. It is generally assumed that a TF should have similar binding patterns in cells from the same or closely related tissues. Surprisingly, this assumption has not been carefully examined. To this end, we systematically compared the genomic binding of the cell cycle regulat...

The lack of effective treatment targets for triple-negative breast cancers make them unfitted for endocrine or HER2 targeted therapy, and their prognosis is poor. Transcription factor ER81, a downstream gene of the HER2, is highly expressed in breast cancer lines, breast atypical hyperplasia and primary breast cancers including triple-negative examples. However, whether and how ER81 affects bre...

Bone metastasis is one of the most severe cancer complications. To analyze the mechanism of bone metastasis, we established highly invasive cell lines from the human breast cancer cell line MDA-MB-231 using an in vitro sequential selection system. The cell lines, MDA-231-S10 and MDA-231-S5, were more invasive and more motile than the parental cell line. Moreover, MDA-231-S10 metastasized to bon...

2-Phenyl-6,7-difluoro and 2-(4-fluorophenyl)quinazoline derivatives bearing salicylidenhydrazino fragments at position 4 were prepared based on 4,5-difluoroantranilic acid or anthranilamide. Molecular docking to casein kinase 2 was performed; compounds with high in silico activity CK2 revealed. Cytotoxic of the synthesized studied cancer cell line MDA-MB-231 normal WI26 VA4.

Epimers of ginsenoside Rg3 (Rg3) have a low bioavailability and are prone to deglycosylation, which produces epimers Rh2 (S–Rh2 R–Rh2) protopanaxadiol (S-PPD R-PPD). The aim this study was compare the efficacy potency these molecules as anti-cancer agents. Crystal violet staining used anti-proliferatory action on human epithelial breast cancer cell line, MDA-MB-231, umbilical vein endothelial c...

An emphasis in early detection and more effective treatments has decreased the mortality rate of breast cancer. Despite this decrease, breast cancer continues to be the leading cause of death among women between 40 and 55 years of age and is the second overall cause of death among women. Hence, the aim of the present study was to assess the therapeutic efficacy of deguelin, a rotenoid isolated ...

We hypothesized that dysregulation of lactate/pyruvate (monocarboxylate) transporters (MCT) and lactate dehydrogenase (LDH) isoforms contribute to the Warburg effect in cancer. Therefore, we assayed for the expression levels and the localizations of MCT (1, 2, and 4), and LDH (A and B) isoforms in breast cancer cell lines MCF-7 and MDA-MB-231 and compared results with those from a control, untr...

Benzyl isothiocyanate (BITC), a constituent of edible cruciferous vegetables, decreases viability of cancer cells by causing apoptosis but the mechanism of cell death is not fully understood. The present study was undertaken to determine the role of Bcl-2 family proteins in BITC-induced apoptosis using MDA-MB-231 (breast), MCF-7 (breast), and HCT-116 (colon) human cancer cells. The B-cell lymph...
