The adverse health effects linked with chromium and manganese and the diverse cellular and molecular effects of chromium and manganese make the study of chromium and manganese carcinogenesis and toxicology very interesting and complex. Quantitative elemental analysis of scalp hair of breast cancer
Long-chain unsaturated free fatty acids have been shown to inhibit the immune responses of lymphocytes in vivo and in transformation and macrophage inhibition factor assays in vitro. The purpose of this study was to test the effect of linoleic acid on naturally occurring lymphocytotoxicity in a 51Cr
BACKGROUND
The immune system may influence tumorogenesis through natural killer (NK) and specific T cytotoxic cells. It is considered that NK cells, which constitute 15% of peripheral blood lymphocytes, have a main role in defense, due to their ability to destroy tumor cells in situ or in the blood
The study aimed to evaluate immune-stimulating effects of a well-known Thai folkloric remedy when used for adjuvant therapy with conventional chemotherapeutics for treatment of breast cancer. Immunostimulating influence of the remedy (215 mg/kg body weight per day) on NK cell activity and TNF-α
The cytotoxic capacity of resting, interleukin-2 (IL-2)-stimulated and in vitro cultured (3-5 days in 10 U/ml IL-2 containing media) peripheral blood lymphocytes (PBLs) from breast cancer patients to a panel of established mammary tumor cell lines was ascertained. Significant cytolysis (ranging from
BACKGROUND
Trastuzumab, an anti-HER2/neu monoclonal antibody, is thought to promote HER2/neu receptor internalization and/or turnover. This study was designed to investigate the kinetics of trastuzumab treatment on tumor cells with varying levels of HER2/neu expression and to determine the effect of
Mononuclear cells from 115 individuals were tested in a 4-h chromium release assay against two breast-cancer-derived cell lines, G11 and MCF-7, and a myeloid line, K-562, shown previously to be sensitive to natural cytotoxicity. These data were analyzed in a manner designed to detect hyperreactivity
BACKGROUND
Evidence exists that prognosis in breast cancer may be related to the timing of primary surgery. Fluctuations in natural killer (NK) cells and/or their sensitivity to surgical stress hormones could mediate this phenomenon. We sought to establish, firstly, if there are any numerical or
BACKGROUND
The process of pathological biomineralization plays an important part in the morphogenesis of tumors. The role of heavy metal salts in the pathological mineralization of breast cancer tissue should not be ruled out, considering their ability to enter into covalent bonds with calcium salt
The toxic metals arsenic(III) and chromium(VI) are considered human carcinogens, although they may act through different mechanisms. We previously showed that when administered at single low, non-overtly toxic doses, chromium, arsenic, and several other chemical carcinogens preferentially alter
Several metals have carcinogenic properties, but their associations with breast cancer are not established. We studied cadmium, a metalloestrogen, and 9 other metals-arsenic, cobalt, chromium, copper, mercury, molybdenum, lead, tin, and vanadium--in relation to young-onset breast cancer (diagnosis
Several metals have carcinogenic properties, but their associations with breast cancer are not established. We studied cadmium, a metalloestrogen, and 9 other metals-arsenic, cobalt, chromium, copper, mercury, molybdenum, lead, tin, and vanadium--in relation to young-onset breast cancer (diagnosis
Epidemiologic studies demonstrated that the environment serves a crucial role in cancer development. Heavy metals, including arsenic (As), cadmium (cd), chromium (Cr), lead and mercury, are considered to be carcinogens or co-carcinogens. Furthermore, Cd has been detected in breast cancer (BC) tissue
Male breast cancer (MBC) is a rare and understudied disease. There is limited evidence on association between environmental and occupational agents and MBC. Some similarities in risk factors may be shared with female breast cancer. We evaluated solvents, metals, exhaust gases and other BACKGROUND
Normal human cells resist the lytic activity of homologous complement (C) by expressing inhibitory molecules on their cell membranes. Recently, it has become increasingly evident that information on C inhibitors on malignant tumor cells is crucial before considering any immunotherapeutic
