The gene encoding the human basic fibroblast growth factor (hbFGF) has been already chemically-synthesized and cloned in pET-3a expression vector (Pasteur Institute of Iran). In the present study, we compared the level of expression of this synthetic hbFGF and its related cDNA in Escherichia coli. The pBR322-cDNA of hbFGF supplied by Dr. Seno (from Molecular Biology Dept, Okaido prefectural uni...

background dedifferentiation of chondrocytes remains a major problem for cartilage tissue engineering. chondrocytes loss differentiated phenotype in in vitro culture that is undesired for repair strategies. the chondrocyte is surrounded by a pericellular matrix (pcm), together forming the chondron. pcm has a positive effect on the maintenance of chondrocyte phenotype during culture in compariso...

background bone marrow and adipose tissue are two main sources of mesenchymal stem cells (mscs). some of studies suggest that there are some differences in gene expression profile of mscs-derived from various tissues. to investigate gene expression profile by qrt-pcr, an appropriate reference gene with stable expression level should be chosen for normalizing data.  this study was designed to ev...

most plants encounter stress such as drought and salinity that adversely affect growth, development and crop productivity. the expression of the gene glutathione-s-transferases (gst) extends throughout various protective mechanisms in plants and allows them to adapt to unfavorable environmental conditions. gstf1 (the first phi gstfs class) gene expression patterns in the wheat cultivars mahuti ...

Background: Glioma is one of the most common and deadliest primary malignant tumors in the brain. A large part of the gene expression products are non-coding protein RNA. LncRNA THRIL gene is an antisense LncRNA and one of the most important mediators of the NF-KB signaling pathway, that express in many tissues of the body, including the central nerve system (CNS). The aim of the present study ...

tgiflx, a homoproteins cluster member located on the x chromosome, has a critical role in male reproduction and prostate development. previous studies have shown the erratic expression of tgiflx gene in a large proportion of prostate tumors. however tgiflx function in prostate development remains unknown. the purpose of this study was to evaluate the consequences of tgiflx expression on prostat...

lipases are versatile biocatalysts with a wide range of application in food, dairy, leather, paper, pharmaceutical and detergent industries.  in this study, mesophilic lipase gene from an indigenous bacillus pumilus f3 that already its gene had been sequenced and  identified, was cloned and expressed in methylotrophic yeast pichia pastoris and codon translation of lipase gene was evaluated in p...
