Background & Objective: In order to enhance the expression of soluble proteins and facilitate their purification and development of multi-functional polypeptide , chimerical recombinant proteins have been invented . The purpose of this study was to construct ctxB-gfp-stxB gene cassette to measure the uptake and excretion of chimerical antigen in future studies.   Materials & Methods: After prep...

Background: Most of colorectal cancers arise from intestinal polyps. Evaluating of the expression level of genes that are involved in tumors growth and development, may consider as diagnostic factor of malignancy in the polyps. Failure of apoptosis is one of the causes of cancers. One of the key molecules in this pathway is Bid gene which connects the extrinsic to the intrinsic apoptosis pathwa...

Bovine chymosin enzyme is one of the most commonly used enzymes in the dairy industry. The production of this enzyme from its natural source does not meet the needs of this huge industry. The production of recombinant bovine chymosin in plants can be a good alternative to native enzyme. Insertion and expression of foreign genes in plants can occur in the nucleus and chloroplast organelles. The ...

Background: Cholestasis occurs as a result of malfunction or secretion of bile; and complications of this disease include apoptosis (planned death). Curcumin is an effective extract of turmeric rhizome that has anti-apoptosis properties. Thus in this study, we investigated the expression of BAX and BCL2 genes following cholestasis and curcumin in the frontal region of male rats. Materials and m...
