Curcumin has been shown to exert potential antitumor activity in vitro and in vivo involved in multiple signaling pathways. However, the application of curcumin is still limited because of its poor hydrophilicity and low bio-availability. In the present study, we investigated the therapeutic effects of a novel and water soluble bis(hydroxymethyl) alkanoate curcuminoid derivative, MTH-3, on huma...

The diverse responses of different cancers to treatments such as photodynamic therapy of cancer (PDT) have fueled a growing need for reliable predictive markers for treatment outcome. In the present work we have studied the differential response of two phenotypically and genotypically different breast adenocarcinoma cell lines, MCF7 and MDA-MB-231, to hypericin PDT (HYP-PDT). MDA-MB-231 cells w...

The engagement of membrane-bound Igs (mIgs) results in growth arrest, accompanied by apoptosis, in the WEHI-231 murine B lymphoma cells, a cell line model representative of primary immature B cells. Inhibitor of differentiation (Id) proteins, members of the helix-loop-helix protein family, functions in proliferation, differentiation, and apoptosis in a variety of cell types. In this study, we a...

In continuation of previous efforts to investigate the biological potency of tetrahydropyridinol derivatives, the present study synthesized three target compounds: N-(bromoacetyl)-3-carboxyethyl-2,6-diphenyl-4-O-(pentafluorobenzoyl)-Δ3-tetra-hydropyridine (5a), N-(chloroacetyl)-3-carboxyethyl-2,6-diphenyl-4-O-(pentafluorobenzoyl)-Δ3-tetrahydropyridine (5b) and N-(2-bromopropanoyl)-3-carboxyethy...

Exogenous sphingosine-1-phosphate (SPP) inhibits chemotactic motility of several transformed cell lines. We have found that SPP at high micromolar concentrations decreased chemotaxis of estrogen-independent (MDA-MB-231 and BT 549) and estrogen-dependent (MCF-7 and ZR75-1) human breast cancer cells. Because SPP has been implicated as a lipid-signaling molecule with novel dual intraand intercellu...


 Purpose: To Investigate the antiproliferative effect of n-hexane-diethyl ether fraction Costus speciosus (NP) on triple negative breast cancer (MDA-MB-231) cells, and mechanism involved.
 Methods: Maceration with methanol (CH3OH) was used for extraction rhizomes. Chromatographic separation to obtain non-polar via elution n-hexane:(C2H5)2O at a volume ratio 9:1. The cytotoxic NP eval...

The microenvironment drives mammary gland development and function, and may influence significantly both malignant behavior and cell growth of mammary cancer cells. By restoring context, and forcing cells to properly interpret native signals from the microenvironment, the cancer cell aberrant behavior can be quelled, and organization re-established. In order to restore functional and morphologi...

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...

Cetuximab resistance is the main obstacle for treatment of EGFR overexpression cancer, including triple-negative breast cancer (TNBC). MicroRNA (miRNA)-155-5p upregulated in TNBC cells; thus, present study explored whether downregulation miR-155-5p enhanced anti-tumor effect cetuximab cells. MDA-MB-231 and MDA-MB-468 cells were infected with lentivirus-epidermal growth factor receptor (EGFR) 72...

Abstract Receptor Expressed in Lymphoid Tissues (RELT) is a human TNFR member that activates NF-kB and implicated several cancers. We therefore sought to characterize the association of RELT with inflammatory bowel disease (IBD) breast cancer (BC). Additionally, we further characterized Filamin A (FLNA), an actin-binding protein can promote tumorigenesis, or counteract tumors, depending on its ...
