ONCOLOGY LETTERS six: 875-877,Cytotoxic effects of caffeic acid undecyl ester are involved inside the inhibition of telomerase activity in NALM-6 human B-cell leukemia cellsAYAKO TOMIZAWA, SYU-ICHI KANNO, YUU OSANAI, SHIN YOMOGIDA and MASAAKI ISHIKAWA Department of Clinical Pharmacotherapeutics, Tohoku Pharmaceutical University, Sendai, Miyagi 981-8558, Japan Received March four, 2013; Accepted July 3, 2013 DOI: ten.Tween 80 3892/ol.2013.1482 Abstract. Our previous study reported that caffeic acid undecyl ester (CAUE) has a potent cytotoxic effect and induces apoptosis in NALM-6 cells, but not in regular human lymphocytes. The majority of normal human cells have no detectable telomerase activity, having said that, activity is commonly detected in cancer cells. Hence, inhibiting telomerase activity and inducing apoptosis may possess a selective impact on cancer cells. The aim of your present study was to investigate the inhibitory effects of telomerase activity by CAUE inside a NALM-6 cell culture technique. CAUE was shown to preferentially damage DNA synthesis compared with RNA or protein synthesis. Furthermore, telomerase activity was drastically suppressed along with the activity of human telomerase reverse transcriptase (hTERT), a subunit of telomerase, was decreased following treatment with CAUE, each and every within a concentration-dependent manner.PMID:24455443 These outcomes indicated that the cytotoxic effects of CAUE are mediated by the inhibition of DNA synthesis and telomerase activity. The present study will be the first to recognize the cytotoxic mechanisms of CAUE in leukemia cells. Introduction Telomerase, a specialized ribonucleoprotein, plays an necessary part in cell proliferation by safeguarding against the issue of end-replication by adding TTAGGG repeats to telomeres (1). The majority of normal human cells have no detectable telomerase activity, even so, activity is frequently detected in cancer cells (2,3). The inhibition of telomerase causes a progressive and critical reduction of telomeres, leading to a potent signal for the blockage of cell proliferation plus the induction of apoptosis (4). Targeting the inhibition of telomerase activity along with the induction of apoptosis may well possess a selective effect on cancer cells. Clinically, B-cell acute lymphoblastic leukemia is curable, having said that, 50 of adults experience treatment failure as a consequence of drug resistance as well as the inability of older adults to tolerate the side-effects of therapy (five). Hence, it is actually.
