Regarding molecular factors, all driver mutations in lung adenocarcinoma had a favorable effect (EGFR, HR 0.53, 95%CI 0.31-0.89; ALK, HR 0.28, 95%CI 0.12-0.66; KRAS, HR 0.65, 95%CI 0.47-0.92), triple negative status predicted poor prognosis in breast adenocarcinoma (HR 2.04, 95%CI 1.13-3.69), while no effect of BRAF/NRAS mutations was demonstrated in melanoma BMs.
The most active compounds 3h (IC<sub>50</sub> = 0.067 μM against MCF-7) and 3l (IC<sub>50</sub> = 0.027 μM against HepG2) were further tested for Epidermal Growth Factor Receptor (EGFR) inhibitory activity.
H125, a lung adenosquamous carcinoma, and A431, a vulvar epidermoid carcinoma, cell lines express intermediate and high levels of EGFR, respectively, whereas MDA MB231, a breast adenocarcinoma cell line expresses undetectable levels of EGFR measured by flow cytometry/FACS.
Transactivation studies using an EGR1 expression vector co-transfected with a reporter construct containing the 280-bp region showed EGR1-activated heparanase promoter activity in a dose-dependent manner in prostate or breast adenocarcinoma and colon carcinoma cell lines.
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.
Flow cytometry (A60-Micro, Apogee) was used to evaluate the ability of the generic EV markers calcein acetoxymethyl ester, calcein acetoxymethyl ester violet, carboxyfluorescein succinimidyl ester (CFSE), 4-(2-[6-(dioctylamino)-2-naphthalenyl]ethenyl)-1-(3-sulfopropyl)pyridinium (di-8-ANEPPS), and lactadherin to stain EVs from MCF7 human breast adenocarcinoma cell line-conditioned culture medium [epithelial cell adhesion molecule positive (EpCAM<sup>+</sup>)] or platelet EVs from human plasma [integrin β3 positive (CD61<sup>+</sup>)].
Epithelial cell adhesion molecule aptamer conjugated PEG-PLGA nanopolymersomes for targeted delivery of doxorubicin to human breast adenocarcinoma cell line in vitro.
Anti-EpCAM-conjugated nano/hybrid magnetic microgels are used to isolate EpCAM-expressing breast adenocarcinoma MCF-7 cells from culture media and whole blood with an efficiency of 75 and 70%, respectively.
However, while investigating the ephrinA1/EphA2 system in the pathobiology of glioblastoma multiforme (GBM), we uncovered that ephrinA1 is released from GBM and breast adenocarcinoma cells as a soluble, monomeric protein and is a functional form of the ligand in this state.
Cytotoxicity studies on both cancerous (human breast adenocarcinoma MCF-7) and normal (Human embryonic kidney HEK-293) cell lines revealed their excellent biocompatibility.
Novel Mannich base derivatives of glabridin were synthesized and their antiproliferative activity were performed along with our previously reported glabridin-chalcone hybrids molecules (GCHMs) against various human cell lines MDA-MB-231 (breast adenocarcinoma), HEK-293 (embryonic kidney cell line), K562 (leukemia), MCF-7 (breast adenocarcinoma), HeLa (cervix adenocarcinoma), HepG2 (hepatocellular carcinoma) and WRL-68 (hepatic carcinoma).
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).
The incidence of topoisomerase II-alpha genomic alterations in adenocarcinoma of the breast and their relationship to human epidermal growth factor receptor-2 gene amplification: a fluorescence in situ hybridization study.
Fifty patients with typical infiltrating ductal adenocarcinoma of the breast were studied for amplification of the c-erb B-2 (neu/HER-2) oncogene within the tumor DNA.
We report the case of an 82-year-old male patient with a > 8-year history of prostate cancer (PrCa), who developed breast adenocarcinoma (BrCa) (Ki-67+ and negative for ER, PR, PSA and HER2/neu) after prolonged (approximately 7-year) anti-androgen (flutamide) monotherapy for locally advanced PrCa.
Patients ≥ 18 years of age with histologically-confirmed HER2-positive adenocarcinoma of the breast (clinical T1-T3, N0-N2, M0), normal left ventricular ejection fraction, and adequate organ function received trastuzumab 6 mg/kg intravenous (I.V.)
Fluorescence in situ hybridization (FISH) as primary methodology for the assessment of HER2 Status in adenocarcinoma of the breast: a single institution experience.
This observational study was conducted in patients with HER2-positive breast adenocarcinoma ≤1.5 cm who received trastuzumab-based adjuvant treatment in clinical practice.
Twenty-six women with newly diagnosed stage II to III histologically or cytologically proven adenocarcinoma of the breast with negative HER2 status were enrolled.
We found that recombinant protein 4D5scFv-miniSOG exerts a highly specific photo-induced cytotoxic effect on HER2/neu-positive human breast adenocarcinoma SK-BR-3 cells (IC50= 160 nM).
The influence of polysomy 17 on HER2 gene and protein expression in adenocarcinoma of the breast: a fluorescent in situ hybridization, immunohistochemical, and isotopic mRNA in situ hybridization study.
