In the present study, we used a cloned derivative, KYM-1D4, of the human rhabdomyosarcoma cell line, KYM-1, known to express high numbers of the two tumor necrosis factor (TNF) receptors, TR60 and TR80, and to be highly sensitive to TNF alpha-mediated cytotoxicity/antiproliferation, to investigate the role of TR60 and TR80 in protein phosphorylation. Using permeabilized KYM-1D4 cells, it was fo...

Aneuploidy, an incorrect chromosome number, is a hallmark of cancer. Compounds that cause lethality in aneuploid, but not euploid, cells could therefore provide new cancer therapies. We have identified the energy stress-inducing agent AICAR, the protein folding inhibitor 17-AAG, and the autophagy inhibitor chloroquine as exhibiting this property. AICAR induces p53-mediated apoptosis in primary ...

Plants, particularly fruits and vegetables, have many phytochemicals that possess various bioactivities, including antioxidant and anticancer properties. In this study, the aim was to investigate the antiproliferative properties of Syzygium fruits, namely water apple (Syzygium aqueum), milk apple (Syzygium malaccense), and malay apple (Syzygium malaccense L.) against two types of cancer-origin ...

Abstract: Plants produce a variety of secondary metabolites, one which is essential oils that contain volatile compounds and are useful for humans. Cymbopogon nardus contains can inhibit the proliferation cancer cells. This research aims to explore antiproliferation activity C.nardus’ with different concentrations against breast Michigan Cancer Foundation-7 (MCF-7) Antiproliferation test was ca...

The response of renal epithelial cells to injury can include hyperplasia (increase in cell number), apoptosis (cell death), antiproliferation (growth arrest), or hypertrophy (cells physically enlarge). Examining cell size and the protein:DNA ratio can differentiate between the growth response patterns, but it is proposed that the degree of activation of cyclin D kinase in the late G1 phase of t...

A facile synthesis of 3-methylthio-3-arylamino-2-cyanoacrylates from 3,3-dimethylthioacrylate and aromatic amines or amino pyridines has been achieved in moderate to high yields (64.0% ~ 93.5%) in 30 minutes at 50 degrees C under microwave irradiation. This method is very simple and the reaction conditions are mild, environmentally friendly and more importantly, quick. In the 3-(4,5-dimethylthi...
