Glucose deprivation is a factor evoking endoplasmic reticulum (ER) stress and induction of expression of an oxygen-regulated protein of 150 kDa (ORP150). We studied the effect of inducible overexpression of ORP150 on senescence and apoptosis of human breast carcinoma cells (MCF7) and human skin fibroblasts. We found an inhibitory effect of ORP150 on apoptosis and senescence of MCF7 cells, but n...

introduction: trastuzumab is a monoclonal antibody that is used in treating breast cancer. we labeled this monoclonal antibody with technetium-99m and performed in vitro and in vivo quality control tests as a first step in the production of a new radiopharmaceutical. methods: trastuzumab was labeled with technetium-99m using succinimidyl hydrazinonicotinamide (hynic) as chelator. radiochemical ...

Treatment options specifically targeting tumour cells are urgently needed in order to reduce the side effects accompanied by chemo- or radiotherapy. Differences in subcellular structure between tumour and normal cells determine their specific elasticity. These structural differences can be utilised by low-frequency ultrasound in order to specifically induce cytotoxicity of tumour cells. For fur...

PURPOSE Suppressor of cytokine signaling 7 (SOCS7) is a member of the SOCS family and is known to interact with phospholipase Cγ-1 (PLCγ-1), a key downstream mediator of the hepatocyte growth factor (HGF)/C-MET axis. Here, we report our observations of the effect of knocking down SOCS7 gene on the behaviour of breast cancer cells both in vitro and in vivo and to elucidate whether this involves ...

The role of PPARβ/δ in breast carcinogenesis remains unclear because some studies show that activating this receptor promotes breast cancer cell growth, while other studies show that activating this receptor inhibits breast cancer cell growth. Further, some studies suggest that the function of PPARβ/δ can be altered by the presence of fatty acid binding protein 5 (FABP5) and cell retinoic acid ...

The treatment of breast cancer by retinoic acid (RA) may be mediated by lipid peroxidation. Expression of metallothionein (MT) in cancer cells, however, can protect against lipid peroxidation by scavenging hydroxyl radicals. In this study, a two-by-six factorial design was used to investigate the interactive effects of all-trans-RA and zinc (Zn)-induced MT on the growth of two human breast canc...

It has previously been shown that highly invasive MDA-MB231 human breast cancer cells express vacuolar proton-translocating ATPase (V-ATPases) at the cell surface, whereas the poorly invasive MCF7 cell line does not. Bafilomycin, a specific V-ATPase inhibitor, reduces the in vitro invasion of MB231 cells but not MCF7 cells. Targeting of V-ATPases to different cellular membranes is controlled by...

Abstract Introduction Polymeric immunoglobulin receptor (PIGR) has a major role in mucosal immunity as transporter of polymeric across the epithelial cells. PIGR expression increases various cancers and relates to patient outcomes. Functional roles have been explored several such hepatocellular, pancreatic lung cancer. The aim this study was determine effect on cellular behaviours chemo-sensiti...

Today, plant compounds and substances of natural origin as bio products are strongly recommended for the prevention treatment cancer. In field biomedicine anti-viral, anti-inflammatory, anti-oxidant properties among most known activities Humus obtained from humus. this study, effect humic fulvic acids (HA, FA), product humus, on breast cancer cells (MCF7), common women, was investigated. To ach...

Turmeric or Curcuma longa Linn is one of the native spices and medicinal plants from Southeast Asia. contains a compound named curcumin. Curcumin (diferuloylmethane) yellow pigment in turmeric that widely used as spice, food coloring (curry) preservative. shows various pharmacological effects have been reported scientifically research, which an anticancer. This study aims to perform cytotoxic t...
