Aptamer-based photoelectrochemical assay for the determination of MCF-7

Mikrochimica Acta, 2020
In 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, 2011
Abstract 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, 2004
AbstractBackground 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, 2005
Human 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+/

Therapeutic Observations in MCF-7 Aromatase Xenografts

Clinical Cancer Research, 2005
Abstract 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.

Phosphatidylcholine catabolism in the MCF-7 cell cycle

Biochemistry and Cell Biology, 2006
The 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.

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, 2001
Previous 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 ...

Phytoestrogens on the Proliferation of Breast Cancer Cell MCF - 7

Tobacco Regulatory Science, 2021
A 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.

SSCF-Hyperthermia Study in MCF-7 Spheroids – In Silicio

2021
Electromagnetic hyperthermia is an alternative treatment for cancer that has been carried out as an adjuvant to other cancer treatments such as chemotherapy and radiotherapy; this study shows the interaction between a cell culture of three dimensional MCF-7 spheroids (Michigan Cancer Foundation-7) inside a culture media and the electromagnetic ...

Optimization of estrogen growth response in MCF-7 cells

In Vitro Cellular & Developmental Biology - Animal, 1992
The factors involved in estradiol-17 beta induced growth stimulation of MCF-7 human breast cancer cells have been examined. Wild type MCF-7 cells (and clone E3) were shown to undergo slow growth in phenol-red-free medium containing specific calf sera. The E3 clone was used to document a mean 6-day growth stimulation of 3.35-fold (doubling time = 33 +/-
