The molecular basis of cross-resistance to tumor necrosis factor (TNF) and Adriamycin has been investigated using the breast adenocarcinoma cell line MCF7/p, its Adriamycin-resistant counterpart MCF7AdrR, and the MDR1 gene-transduced MCF-7 cells (MCF7/MDR1).
Compounds <b>1</b>-<b>17</b> were evaluated for inhibitory effects on P-glycoprotein (P-gp) in an adriamycin (ADM)-resistant human breast adenocarcinoma cell line (MCF-7/ADR) and neuroprotective effects against serum deprivation-induced and rotenone-induced PC12 cell damage.
In the present study, two plasmid vectors have been designed to express the wild-type full-length BCRP cDNA enforced driven by its endogenous promoter containing a functional ERE and a constitutive cytomegalovirus (CMV) promoter as control, respectively, which were transfected into estrogen-responsive MCF-7 and estrogen-independent MDA-MB-231 human breast adenocarcinoma cell lines.
The 410.4 murine breast adenocarcinoma cell line was initially evaluated in vitro for its interactions with LPD-PEG-Folate and control LPD-PEG formulations.
We used a tumour necrosis factor (TNF)-alpha resistant breast adenocarcinoma MCF-7 cell line to investigate the involvement of the actin cytoskeleton in the mechanism of cell resistance to this cytokine.
The aim of the present study was to study the impact of altered actin transport between the cytoplasm and nucleus by the downregulation of importin-9 (IPO9) in breast adenocarcinoma MCF-7 cells exposed to an apoptosis-inducing combination of garlic-derived S-allyl-L-cysteine sulfoxide (alliin) and paclitaxel (PTX).
Sequence analysis of clones obtained from a human breast adenocarcinoma MCF7 cDNA library suggests that at least three mRNA transcripts, differing in their 3'-untranslated regions, are transcribed from the hAG-2 gene.
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.
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.
In the present study, we aim to determine the anti-MDR effects of pyramidatine (Z88), a cinnamic acid-derived bisamide compound isolated from the leaves of Aglaia perviridis, on KB/VCR (vincristineresistant human oral cancer cells) and MCF-7/ADR (adriamycin-resistant human breast adenocarcinoma) cells.
Compounds <b>1</b>-<b>17</b> were evaluated for inhibitory effects on P-glycoprotein (P-gp) in an adriamycin (ADM)-resistant human breast adenocarcinoma cell line (MCF-7/ADR) and neuroprotective effects against serum deprivation-induced and rotenone-induced PC12 cell damage.
Conjugation of anti-VEGF antibodies with bovine serum albumin coated PEGylated magnetic nanoparticles allows for improved binding with murine breast adenocarcinoma 4T1 cell line and facilitates doxorubicin delivery to tumor cells.
Three different stable human breast adenocarcinoma sublines that overexpress ALDH3A1 and certain other enzymes, apparently as a consequence of constitutively upregulated gene transcription mediated by transactivated EpREs (electrophile responsive elements) present in the 5'-upstream regions of these genes.
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).
Cytotoxicity assay (MTT), flow-cytometric univariate cell cycle analysis, Annexin V-FITC staining and DNA fragmentation for cell death mechanism suggested that compound 3d with chloro-substituted phenyl ring induced enhanced cytotoxicity by an apoptotic pathway with high differential toxicity to breast adenocarcinoma cells (MCF-7) when compared with normal human dermal fibroblast cells.
Accumulating evidence indicates that androgens and the androgen receptor modulate the development and progression of breast adenocarcinoma; however, the precise role and actions remain poorly defined.
Flow cytometric analyses of MCF7 cells with MEAD (15 mg/ml and 20 mg/ml) for 24 h demonstrated cell cycle arrest at 'S' phase; increased p53, Bax protein expression; caspase 3activation and decreased the mitochondrial membrane potential (MMP).
Reduced expression of proapoptotic gene BAX is associated with poor response rates to combination chemotherapy and shorter survival in women with metastatic breast adenocarcinoma.
