Antitumor activity for the prepared compounds against human breast adenocarcinoma (MCF-7), liver (HEPG2) and colon (HCT116) cancer cell lines was evaluated using SRB assay method.
Furthermore, the synthesized compounds were evaluated for their <i>in vitro</i> anti-proliferative activities against human epithelial lung carcinoma (A549), human epithelial cervical cancer (HeLa), human breast adenocarcinoma (MCF7) and human neuroblastoma (IMR32) cell lines using the SRB assay.
Using the monoclonal antibody (MAb) MRK20 the immunohistochemical expression of the 85-kd membrane protein (MP)/cell adhesion molecule (CAM) CD36 was investigated in tumors from 41 patients with untreated breast adenocarcinoma.
Therefore, <i>in vitro</i> experiments with human lymphoma cell lines SU-DHL-4 and Daudi (both CD40 positive) and human breast adenocarcinoma MCF-7 (GITRL positive) were performed and the secretion of interferon (IFN)-γ was measured.
In this study, the MacLow mouse model of doxycycline-inducible and selective CD68+ macrophage depletion was crossed with the murine mammary tumor virus (MMTV)-Polyoma virus middle T antigen (PyMT) mouse model of spontaneous ductal breast adenocarcinoma to generate the PyMT-MacLow line.
Using human breast adenocarcinoma MCF-7 cells and immortalized human mammary epithelial MCF-10A cells, we determined the effects of 6-NC on the expression of p53 protein and its direct downstream target cyclin-dependent kinase inhibitor p21(Cip1) as well as on the cell cycle progression.
Novel synthetic triterpenoid methyl 25-hydroxy-3-oxoolean-12-en-28-oate induces apoptosis through JNK and p38 MAPK pathways in human breast adenocarcinoma MCF-7 cells.
The LIM domain protein FHL1C interacts with tight junction protein ZO-1 contributing to the epithelial-mesenchymal transition (EMT) of a breast adenocarcinoma cell line.
In order to analyze the trafficking of cathepsin B in living cells, we utilized enhanced green fluorescent protein (EGFP) fused to various cathepsin B constructs for transfecting two cell lines: an invasive human breast adenocarcinoma cell line (BT20) and a cathepsin B deficient mouse embryonic fibroblast cell line (MEF T -/-).
Furthermore, exposure of the H295R cells to isoflavonoids caused a decrease in testosterone production, and various mixtures of PEs significantly stimulated MCF-7 human breast adenocarcinoma cell growth and induced aromatase activity in JEG-3 choriocarcinoma cells.
In human cells, such as HepG2 (human hepatocarcinoma), MCF-7 (human breast adenocarcinoma cell line), and HL-60 (human promyelocytic cell line), the expression of CYP1A1 mRNA was also induced by EA4 treatment.
Expression of the aryl hydrocarbon receptor/transcription factor (AhR) and AhR-regulated CYP1 gene transcripts in a rat model of mammary tumorigenesis.
With the purpose of evaluating their effect on breast cancer biology, o,p'-DDT, p,p'-DDE, and p,p'-DDD (50-1000 nM) were tested on two human breast adenocarcinoma cell lines: MCF-7 expressing estrogen receptor (ER) α and MDA-MB-231 negative for ERα, regarding cell proliferation and viability in addition to their invasive potential.
The cytotoxicity of the compounds and cisplatin was tested against cancer cell lines: mouse colon carcinoma (CT26; <sup>1-PSG</sup>IC<sub>50</sub> = 3.12 ± 0.1), human lung adenocarcinoma (A549; <sup>1-PSG</sup>IC<sub>50</sub> = 2.01 ± 0.2) and human breast adenocarcinoma (MCF7; <sup>1-PSG</sup>IC<sub>50</sub> = 0.98 ± 0.2) as well as against primary line of human pulmonary fibroblasts (MRC-5; <sup>1-PSG</sup>IC<sub>50</sub> = 78.56 ± 1.1).
Congener- and concentration-dependent antagonism of 17beta-estradiol (E2)-induced gene expression, rather than induction of ER-dependent gene expression, was observed for the MeSO(2)-PCBs on lucifierase activity in stably transfected human breast adenocarcinoma T47D cells (ER-CALUX) and vitellogenin (vtg) production in primary hepatocytes from male carp fish (Cyprinus carpio) (CARP-HEP/vtg).
EGF was conjugated to SnCe6(ED) through a carrier, such as dextran (Dex) and human serum albumin (HSA), and the photocytotoxicity on the EGF receptor-overexpressing MDA-MB-468 breast adenocarcinoma cell line was evaluated.
Here we report that EGF, which promotes breast cancer tumour growth and survival, rapidly induces PAI-1 expression in the breast adenocarcinoma cell line MCF-7 through the activation of the transcription factor Elk-1.
