Aim: To construct the expression vector containing cDNA encoding Fab against human gamma-seminoprotein and express it in E. coli.
Methods: The genes encoding K chain and Fd against gamma-seminoprotein were acquired from pUC19-K and pBluescript KS( M13-)-Fd by restrictive enzyme digestion and then cloned into the expression vector pComb3 to construct recombinant expression vector pComb3-Fab. pComb3-Fab was transfected into and expressed in XLI-Blue.
Results: Fab against r-semino-protein was expressed in. XLI-Blue. Western blot analysis and immunocytochemical staining demonstrated that ex-pressed Fab could specifically bind to gamma-seminoprotein.
Conclusion: Fab against gamma -seminoprotein has been expressed successfully with biological activity, which create favourable condition for further study on targeted therapy of prostate cancer.

Unlabelled: Cartilage and joint damage can lead to cartilage degeneration. Bone marrow mesenchymal stem cells (BMSCs) have the potential to address cartilage damage. Hence, this study probed the mechanism of BMSC-extracellular matrix (BMSC-ECM) in promoting damaged chondrocyte repair by regulating the Notch1/RBPJ pathway.

We integrated classic omics, including DNA mutation and RNA gene expression, added a novel focus on promising omics methods based on A>I(G) RNA editing, and developed a drug response prediction model. We analyzed 104 patients from the Breast Cancer Genome-Guided Therapy Study (NCT02022202).

Attempts to treat mouse models of DFNB1 with AAV vectors mediating nonspecific expression have not substantially restored function, perhaps because inappropriate expression in hair cells and neurons could compromise their electrical activity.

To date, 46,000 tyrosines have been observed in human proteins, but relatively little is known about the function and regulation of most of these sites. A major challenge has been producing recombinant phospho-proteins in order to test the effects of phosphorylation.

Contemporary therapies following heart failure center on regenerative approaches to account for the loss of cardiomyocytes and limited regenerative capacity of the adult heart. While the delivery of cardiac progenitor cells has been shown to improve cardiac function and repair following injury, recent evidence has suggested that their paracrine effects (or secretome) provides a significant contribution towards modulating regeneration, rather than the progenitor cells intrinsically. The direct delivery of secretory biomolecules, however, remains a challenge due to their lack of stability and tissue retention, limiting their prolonged therapeutic efficacy.
