A recombinant chimeric plasminogen activator (f beta/scuPA-32k), with a fibrin beta-chain peptide (comprising Gly15 through Arg 42) linked to the N-terminal of a low molecular mass (32 kDa) single-chain urokinase (scuPA-32k, comprising Leu144 through Leu 411) via a 50 amino acid linker sequence, was produced by expression the corresponding chimeric cDNA in(More)
A recombinant chimeric plasminogen activator (GHRP-scu-PA-32K), consisting of the tetrapeptide Gly-His-Arg-Pro fused to the N-terminus of the low-molecular single-chain urokinase-type plasminogen activator (Leu144-Leu411), was produced by expression in CHO cells. The stable expression cell line was selected for large-scale expression. The product was(More)
Although the key metabolic regulatory functions of mammalian peroxisome proliferator-activated receptor α (PPARα) have been thoroughly studied, the molecular mechanisms and metabolic regulation of PPARα activation in fish are less known. In the first part of the present study, Nile tilapia (Nt)PPARα was cloned and identified, and high mRNA expression levels(More)
BACKGROUND Visceral adipose tissue (VAT) and subcutaneous adipose tissue (SCAT) have different structures and metabolic functions, and play different roles in the regulation of mammal systemic endocrine. However, little is known about morphology and physiological and metabolic functions between VAT and SCAT in fish. METHODS We compared the morphological,(More)
A recombinant mutant gene with thrombolytic and antithrombolytic bifunction was expressed in E. coli. Owing to two reasons of high molecular weight and over expression, dscuPA existed in inclusion body form. The protein of inclusion body was inactive protein. In order to obtain active protein, inclusion bodies should be denatured and then renatured. We(More)
On the basis of structure analysis and computer modeling of proUK, two-chain DNA fragment encoding RGD peptide was inserted into the corresponding proUK cDNA site between Gly118-Leu119, using site-directed mutagenesis and DNA recombinant techniques. The chimeric gene was expressed in methylotrophic yeast Pichia pastoris expression system. The chimeric(More)
