A new series of anti-cancer agents based on 1,2-diaryl-5,6-dihydropyrrolo[2,1-a]isoquinoline scaffold containing N,N-diethylaminoethoxy, piperidinylethoxy or morpholinylethoxy group at the para position of the C-2 phenyl ring were synthesized and their cytotoxic activities were assessed against several human cancer cell lines including MCF-7 (ER positive breast cancer cell), MDA-MB231 (ER-ne...
We present the levitation and residing at particular places of human breast cancer (T47D) cells on a magnetic microsystem quickly fabricated by printing. The consists arrays soft elements is put adjacent to bulk magnet. Under field generated magnet, are magnetized, obtaining significant strength high gradient in micro-space above them. applies force as they dropped surfaces elements. As result,...
We hypothesized that aldehyde dehydrogenase1 (ALDH1) protects cancer cells from retinaldehyde-induced cytotoxicity, and that targeting this enzyme would enhance the therapeutic effect of retinaldehyde. ALDEFLUOR™ assays showed high ALDH activity in A549 and H522 cancer cells and low activity in H1666 and T47D cancer cells. Immunoblots showed that expression of ALDH1A1 and ALDH1A3 was high in A5...
Breast cancers treated with the antiestrogen tamoxifen invariably become resistant. To analyze the behavior of cell subpopulations within a tumor following tamoxifen treatment, we have used a new flow cytometry-based ¡mmunoassay and software that simultaneously quantitate PR levels and the DNA indices of ploidy and cell cycle stage in total cell populations or any subset thereof. The human bre...
AIM It is known that botulinum neurotoxin type A (BoNTA) improves some kinds of cancer (e.g. prostate) and that synaptic vesicle glycoprotein 2 (SV2) is the molecular target of this neurotoxin. Besides having potential therapeutic value, this glycoprotein has recently been proposed as a molecular marker for several types of cancer. Although the mechanisms of cancer development and the improveme...
Objective: Breast cancer is one of the most significant causes of female cancer death worldwide. Although several chemotherapeutics have been developed to treat this type of cancer, issues remain such as low survival rates and high reoccurrence after chemotherapy and radiotherapy. To explore a chemopreventive approach to enhancing breast cancer treatment efficacy, the antiproliferative effects ...
Despite the widespread use of medicinal herbs to prevent and treat many diseases, including cancer, there are insufficient scientific data on the safety and efficacy of the majority of herbal therapies. The aim of this study was to assess the effect of a unique Chinese herbal therapy (CHT) from controlled manufactured concentrated powders, on an in vitro model of breast cancer. Three breast ade...
Detection of cytokeratin-19 (CK19) expression as an epithelial-specific marker in circulating tumor cells (CTCs) of breast cancer patients can be important for diagnostic purposes. Comparison of CK19 expression in breast cancer cell lines can indicate that expression of this marker is different in various breast cancer cell lines based on their category. Thirty-five breast cancer patients were ...
