effects of disulfiram on apoptosis in panc-1 human pancreatic cancer cell line

چکیده

pancreatic carcinoma is currently considered as a rapidly progressive and fatal disease, and is typically diagnosed late in its natural course. it is characterized by a poor diagnosis and lack of response to conventional therapy. recent studies have suggested that disulfiram (dsf), a member of the dithiocarbamate family, may have antitumor activity. this study aimed to evaluate the in vitro effect of dsf on apoptosis in human pancreatic cancerous cell line (panc-1). panc-1  cells were cultured and treated with dsf at doses of 5, 10, 13 µm for 24 h and apoptosis was measured. methylation specific pcr (ms-pcr) and real-time quantitative pcr were carried out to detect the methylation pattern and to estimate the mrna expression levels of rassf1a, p21 and bax. ms-pcr analysis demonstrated that no unmethylated band was apeared in panc-1 cell line after dsf treatments. the real-time quantitative pcr results showed no significant mrna expression for rassf1a ( p> 0.05); whereas p21 and bax expression were significantly ( p< 0.01) enhanced after treatment with dsf. the results of the current study indicated that dsf can induce appoptosis in panc-1 through p21 and bax pathway but not through rassf1a.

Effects of disulfiram on apoptosis in PANC-1 human pancreatic cancer cell line

Pancreatic carcinoma is currently considered as a rapidly progressive and fatal disease, and is typically diagnosed late in its natural course. It is characterized by a poor diagnosis and lack of response to conventional therapy. Recent studies have suggested that disulfiram (DSF), a member of the dithiocarbamate family, may have antitumor activity. This study aimed to evaluate the in vitro eff...

Cytotoxic effect of pyocyanin on human pancreatic cancer cell line (Panc-1)

Objective(s): Pyocyanin, a blue-green pigment produced by Pseudomonas aeruginosa, interferes with host redox cycles, which can lead to generation of reactive oxygen species and progressive cellular oxidative damage. The aim of this study was to assess the influence of pyocyanin on human pancreatic cancer cell line.Materials and Methods: Polymerase Chain Reaction (PCR) was applied to confirm the...

An Effective Concentration of 5-Aza-CdR to Induce Cell Death and Apoptosis in Human Pancreatic Cancer Cell Line through Reactivating RASSF1A and Up-Regulation of Bax Genes

Background: Promoter hyper-methylation of tumor suppressor genes is a common event that occurs in cancer. As methylation is a reversible modification, agents capable of reversing an abnormal methylation status should help to combat cancer. 5-Aza-CdR is a DNA methyl-transferase inhibitor. The present study aimed to evaluate the effect of 5-Aza-CdR on the proliferation of human pancreatic cancer ...

Apoptosis Induction of Salvia chorassanica Root Extract on Human Cervical Cancer Cell Line

Salvia chorassanica Bunge is one of the Iranian endemic species of Salvia. There is not any reported literature on S. chorassanica. This study was designed to examine the in-vitro anti-proliferative and proapoptotic effects of the methanol extract of S. chorassanica and its fractions on HeLa cell line. Cells were cultured in EX-CELL®, an animal free medium specially designed for HeLa cell line ...

Metabolic characterization of invaded cells of the pancreatic cancer cell line, PANC‐1

We previously reported that about 0.4% of cells in the cultured human pancreatic cancer cell line, PANC-1, can invade matrigel during the transwell invasion assay, suggesting that these invaded PANC-1 cells may have specific characteristics to keep their invasive potential. To identify the metabolic characterization specific in the invaded PANC-1 cells, metabolome analysis of the invaded PANC-1...
