Abstract

Caspase-3 Gene is a unique protease enzyme involved in the initiation and execution of apoptosis process. The aim of this study to investigate the mRNA expressions of caspase-3 on experimentally induced colorectal cancer (CRC) in male albino rats, rats treated with adipose tissue mesenchymal stem cells (MSCs) and curcumin. Forty white male albino rats were divided into four groups 10 in each, Control group (1^st): They received 0.5 ml of 25% DMSO orally once daily, while the other three groups were injected subcutaneously with dimethylhydrazine (DMH) at a dose of 20 mg/kg body weight per week for 4 consecutive weeks. After two weeks of the last DMH dose, the 2^nd Group: left injected with DMH only, the 3^rd group: every rat received one million cells of MSCs interperitoneally once. The 4^th Group: received oral curcumin at a daily dose 100 mg/kg body weight for two weeks. The colon tissue homogenate caspase-3 mRNA expression was assayed by (real-time PCR). Caspase-3 expression level was significantly decreased in the DMH group than that of the control group while it was significantly increased in DMH+MSCs and DMH+curcumin treated groups in comparison with a DMH group. Mesenchymal stem cells and curcumin thought to have an ameliorative effect on colorectal cancer in male albino rats. Thus the development of CRC may involve changes in the mRNA level of the caspase-3 gene.
