OBJECTIVE Immunotherapy using either dendritic cells (DCs) or expanded cytotoxic T cells (CTLs) has received increased interest in the treatment of specific malignancies including metastatic breast cancer (MBC). DCs can be generated ex vivo from monocytes or CD34+ precursors. The ability to expand

The objective of this research is to investigate the suppressive effects of lupeol on MCF-7 breast cancer cells, and explore its mechanism on inhibiting the proliferation of MCF-7 cells based on cell metabonomics and cell cycle. Gas chromatography-mass spectrometry (GC-MS) was used in the cell

This study was targeted on a metabolomic approach to compare the blood serum free amino acid profiles and concentration of confirmed breast cancer (stages I-III) patients to healthy controls in order to establish reliable biomarkers of early detection and prediction of breast cancer. The

In this work, we have analyzed the genetic variation that can alter the expression and the function in BRCA2 gene using computational methods. Out of the total 534 SNPs, 101 were found to be non synonymous (nsSNPs). Among the 7 SNPs in the untranslated region, 3 SNPs were found in 5' and 4 SNPs were

Polychlorinated biphenyls, cytochrome P4501A1 polymorphism, and postmenopausal breast cancer risk.

In experimental systems, polychlorinated biphenyls (PCBs) induce cytochrome P4501A1 (CYP1A1), which is involved in metabolism of steroid hormones and polycyclic aromatic hydrocarbons in humans. A genetic polymorphism coding for a valine to isoleucine substitution in exon 7 has been associated with

The APC gene I1307K variant is rare in Norwegian patients with familial and sporadic colorectal or breast cancer.

Recently, a T-to-A transversion creating an 8-base mononucleotide tract in the APC gene, resulting in substitution of lysine for isoleucine at codon 1307 (I1307K), was found in a subset of Ashkenazi Jews. This sequence variant was most frequent in colorectal cancer patients with a positive family

Influence of cell proliferation and cell cycle phase on expression of estrogen receptor in MCF-7 breast cancer cells.

In the present study, the effects of cell cycle phase and proliferation rate on the expression of specific estrogen binding activity were explored in hormone-dependent human breast cancer cells. A technique was developed to alter the proliferative rate of MCF-7 cells by plating at different

Cytochrome P4501A1 and glutathione S-transferase (M1) genetic polymorphisms and postmenopausal breast cancer risk.

Log ind / Tilmeld

Polycyclic aromatic hydrocarbons, possible human breast carcinogens, are metabolized by cytochrome P4501A1 (CYP1A1) and glutathione S-transferase (GSTM1). A CYP1A1 polymorphism (isoleucine to valine substitution in exon 7) or the null allele for GSTM1 may affect the mutagenic potential of polycyclic

In this case-control study based on 250 women with breast cancer and 250 age-matched controls, we sought to evaluate the role of four polymorphic variants in the CYP1A1 gene in breast cancer susceptibility in Nigerian women. Heterozygosity for the CYP1A1 M1 genotype (CYP1A1 M1 [T/C]) was associated

BACKGROUND Glutathione S-transferases (GSTs) are encoded by a superfamily of genes and play a role in the detoxification of potential carcinogens. In a nested case-control study, we investigated associations between genetic variability in specific GST genes (GSTM1, GSTT1, and GSTP1) and

A study on the association of cytochrome-P450 1A1 polymorphism and breast cancer risk in north Indian women.

Cytochrome P-450 1A1 (CYP1A1) is involved in the 2-hydroxylation of estrogens and mammary carcinogens into 2-hydroxy catechol metabolites. Many commonly occurring single nucleotide polymorphism (SNP) are reported in CYP1A1 in various populations that include, isoleucine to valine substitution at 462

Alterations of the human epidermal growth factor receptor 2 (HER2) protooncogene have been implicated in the carcinogenesis and prognosis of breast cancer. A polymorphism has been identified at codon 655 (ATC/isoleucine to GTC/valine [I655V]) in the transmembrane domain-coding region of this gene,

ERBB2 genetic polymorphism and breast cancer risk in Chinese women: a population-based case-control study.

A polymorphism at codon 655 (ATC/isoleucine to GTC/valine [Ile655Val], rs1801200) in the transmembrane domain-coding region of human ERBB2 gene has been previously evaluated for its association with breast cancer risk with mixed results. We evaluated this polymorphism in association with breast

Cytochrome P4501A1 polymorphism as a susceptibility factor for breast cancer in postmenopausal Chinese women in Taiwan.

The incidence of breast cancer has been greatly increasing in Taiwan over the past two decades. Since cytochrome P4501A1 (CYP1A1) is involved in the metabolism of environmental carcinogens or oestrogen, we hypothesized that CYP1A1 genetic polymorphism may be a susceptibility factor for breast

HER2 codon 655 G-allele is associated with reductions in plasma high-density lipoprotein levels in breast cancer patients treated with tamoxifen.

BACKGROUND Retrospective studies have revealed that overexpression of the epidermal growth factor receptor ErbB-2 (HER2) reduced the efficacy of tamoxifen therapy, which is associated with an increased risk for cardiovascular events. The aim of this study was to evaluate the effects of the HER2
