The methanol and fractionated extracts (hexane, ethyl acetate and water) of Alpinia mutica (Zingiberaceae) rhizomes were investigated for their cytotoxic effect against six human carcinoma cell lines, namely KB, MCF7, A549, Caski, HCT116, HT29 and non-human fibroblast cell line (MRC 5) using an in vitro cytotoxicity assay. The ethyl acetate extract possessed high inhibitory effect against KB, M...
Multidrug resistance is the most predominant phenomenon leading to chemotherapy treatment failure in breast cancer patients. Despite many studies having suggested that overexpression of epidermal growth factor receptor (EGFR) is a potent predictor of malignancy in cancers, systematic research of EGFR in multidrug resistant (MDR) breast cancer cells is lacking. In order to clarify the role of EG...
Previous studies showed that the WTH3 gene functioned as a negative regulator during multidrug resistance (MDR) development in vitro. To understand whether this gene is also involved in clinical drug resistance, hypermethylation at its promoter region observed in cultured MDR MCF7/AdrR cells was examined in primary drug-resistant breast cancer epithelial cells isolated from effusions of breast ...
The present investigation was carried out to evaluate anticancer activity of cow, goat, sheep, mare, donkey and camel milks and their casein and whey proteins against MCF7 cell line. The structure-based properties of the casein proteins were also investigated, using bioinformatics tools to find explanation for their antitumor activities. The effect of different milks and their casein and whey p...
MicroRNAs (miRNAs), are ~22 nucleotides long, non-coding RNAs that control gene expression post-transcriptionally by binding to their target mRNA's 3'UTRs (untranslated regions). Due to their roles in various important regulatory processes and pathways, miRNAs have been implicated in disease mechanisms such as tumorigenesis when their expression is deregulated. To date, a significant number of ...
Physiological concentrations of the green tea extract epigallocatechin-3-gallate (EGCG) caused growth inhibition in estrogen receptor α (ERα)-positive MCF7 cells that was associated with down-regulation of the ERα and reduced insulin-like growth factor binding protein-2 abundance and increased protein abundance of the tumor suppressor genes p53/p21. In contrast to MCF7 cells that have wt p53, E...
PURPOSE Breast cancer is the most common type of cancer in women. Despite various pharmacological developments, the identification of new therapies is still required for treating breast cancer. Crab is often recommended as a traditional medicine for cancer. This study aimed to determine the in vitro effect of a hydroalcoholic crab shell extract on a breast cancer cell line. METHODS In this ex...
Compounds containing triazene ring structure are cytotoxic agents and clinically used as antitumor alkylating agents. In this study, a series of triazene derivatives holding alkyl and aryl moieties were synthesized and proved to be potent cytotoxic agents in-vitro particularly against eight cancer cell lines (PC3, HT29, Hela, HL60, Jurkat, K562, MCF7, HepG2) and a non-cancerous cell line (HUVEC...
It has been previously shown that corticotropin-releasing hormone (CRH) exerts antiproliferative activity on an estrogen-dependent tumor cell line, i.e. human endometrial adenocarcinoma Ishikawa (IK) cells. Here we have investigated the effects of CRH on another estrogen-dependent tumor cell line, human breast cancer MCF7 cells. In this paradigm, CRH given at a fixed concentration of 100 nM sig...
