Aptamer-based photoelectrochemical assay for the determination of MCF-7
Mikrochimica Acta, 2020In this work, an aptamer-based photoelectrochemical (PEC) assay is reported for the determination of MCF-7 breast cancer cells using hexagonal carbon nitride tubes (HCNTs) as photoactive material. The aptamer immobilized on the HCNT surface can specifically bind with mucin 1 protein (MUC1) that is overexpressed on the surface of MCF-7 cell.

Effects of catechin, diclofenac and celecoxib on the proliferation of MCF-7 and LTED MCF-7 cells
Biomedicine & Preventive Nutrition, 2011Abstract Breast cancer is common among women especially after menopause. Inflammation is now considered as a risk factor of cancer and cyclooxygenase-2 (COX-2) enzymes are highly expressed in many cancers. COX-2 is the inducible enzyme responsible for the synthesis of pro-inflammatory prostaglandins. There are evidences that COX inhibitors especially

Effect of 5‐aminolevulinic acid‐mediated photodynamic therapy on MCF‐7 and MCF‐7/ADR cells
Lasers in Surgery and Medicine, 2004AbstractBackground and ObjectivesPhotodynamic therapy (PDT) has been proposed as an alternative approach in overcoming multidrug resistance (MDR) phenotype. To verify whether 5‐aminolevulinic acid (ALA)‐mediated PDT is effective in MDR cells, we studied the protoporphyrin IX (PpIX) content, intracellular localization, and phototoxicity in human breast ...

Cytotoxicity of xanthopterin and isoxanthopterin in MCF-7 cells
Cancer Letters, 2005Human mammary carcinoma MCF-7 cell line responsiveness to the pteridines xanthopterin and isoxanthopterin was studied using the MTS assay for measurement of cell viability. The pteridines were tested at concentrations ranging from 7.8 to 500 microM singly and in 11 isoxanthopterin:xanthopterin ratios. IC50s of xanthopterin and isoxanthopterin were 109+/

Phosphatidylcholine catabolism in the MCF-7 cell cycle
Biochemistry and Cell Biology, 2006The catabolism of phosphatidylcholine (PtdCho) appears to play a key role in regulating the net accumulation of the lipid in the cell cycle. Current protocols for measuring the degradation of PtdCho at specific cell-cycle phases require prolonged periods of incubation with radiolabelled choline.

Therapeutic Observations in MCF-7 Aromatase Xenografts
Clinical Cancer Research, 2005Abstract In previous studies using a xenograft model with tumors of human estrogen receptor (ER)–positive breast cancer cells transfected with aromatase (MCF-7Ca), we explored the antitumor efficacy of treatment combining the nonsteroidal aromatase inhibitor letrozole with tamoxifen.

Invasive and metastatic properties of MCF‐7 cells and rasH‐transfected MCF‐7 cell lines
International Journal of Cancer, 1992AbstractIn vitro invasion and in vivo metastasis assays were performed with a panel of MCF‐7 cells transfected with isogenic constructs of mutated rasH genes. Both increased levels of rasH expression and rasH oncogene activation increased activity of derivative cell lines in in vitro invasion assays.

Phytoestrogens on the Proliferation of Breast Cancer Cell MCF - 7
Tobacco Regulatory Science, 2021A cell is an organic whole containing biological macromolecules such as nucleic acid and protein. Human cells contain about 15,000 proteins, which play an important role in the development of cell life. This article aims to study the effect of phytoestrogens on the proliferation of breast cancer cells MCF - 7.

Low pO2 and β-Estradiol Induce VEGF in MCF-7 and MCF-7-5C Cells: Relationship to in vivo Hypoxia
Breast Cancer Research and Treatment, 2001Previous work from this laboratory demonstrated that MCF-7 breast carcinoma cells grown in nude mice contained minimal hypoxia but that tamoxifen treatment of these tumors resulted in increased hypoxia (Evans S. et al., Cancer Research, 1997). These findings led to studies exploring the link between estrogen signaling and tumor oxygenation and ...

MCF-7 cells lack the expression of Caspase-3
International Journal of Biological Macromolecules, 2023With great interest, we read the paper "Chitosan nano-vehicles as biocompatible delivering tools for a new Ag(I)curcuminoid-Gboxin analog complex in cancer and inflammation therapy" published in the International Journal of Biological Macromolecules.
