α-complex protein 2 (α-CP2) is known as an RNA-binding protein that interacts in a sequence-specific manner with single-stranded polycytosine [poly(C)]. This protein is involved in various post-transcriptional regulations, such as mRNA stabilization and translational regulation. In this study, the full-length mouse α-CP2 gene was expressed in an insoluble form with an N-terminal histidine tag i...

Aging, the main risk factor for Parkinson's disease (PD), is associated with increased α-synuclein levels in substantia nigra pars compacta (SNc). Excess α-synuclein spurs Lewy-like pathology and dysregulates the activity of protein phosphatase 2A (PP2A). PP2A dephosphorylates many neuroproteins, including the catecholamine rate-limiting enzyme, tyrosine hydroxylase (TH). A loss of nigral dopam...

α-Conotoxin LvIA is derived from Conus lividus, native to Hainan, and is the most selective inhibitor of α3β2 nicotinic acetylcholine receptors (nAChRs) known to date. In this study, an efficient approach for the production of recombinant α-Conotoxin LvIA is described. Tandem repeats of a LvIA gene fragment were constructed and fused with a KSI gene and a His₆ tag in a Escherichia coli (E. coli...

Abstract α-Dystroglycan (α-DG) is a highly glycosylated cell-surface protein. Defective O-mannosyl glycan on α-DG associated with muscular dystrophies and cancer. In the biosynthetic pathway of glycan, fukutin (FKTN) fukutin-related protein (FKRP) transfer ribitol phosphate (RboP). Previously, we reported that FKTN FKRP can also glycerol (GroP) from CDP-glycerol (CDP-Gro) showed inhibitory effe...

The aim of the present study was to express the recombinant Chlamydophila pneumoniae (C. pneumoniae) protein, Cpn 0810, in Escherichia coli (E. coli) BL21, and investigate the effects of Cpn 0810 on inflammatory and apoptotic processes in human monocytic (THP-1) cells. An ELISA was performed to detect the levels of the proinflammatory cytokines, tumor necrosis factor (TNF)-α and interleukin (IL...

Background: The tumor necrosis factor alpha (TNFα) is a cytokine that produced principally by monocyte/macrophages and T lymphocytes, respectively. TNFα is recognized as the primary mediator of immunity in inflammation reaction.  One important application of Tumor Necrosis Factor Receptor 2 (TNFR2) is for the treatment of autoimmune diseases like rheumatoid arthritis (RA).<br /...

Herein, we reported an Escherichia coli-based expression and purification method of recombinant porcine interferon alpha (rPoIFN-α). PoIFN-α coding sequence was cloned into pMD18-T vector and then subcloned into pET-32a (+) vector using standard recombinant DNA techniques and the resulting plasmid was transformed into BL21(DE3) competent cells. After induction with isopropyl-β-D-1-thiogalactopy...
