Objective: To investigate the polymorphisms of platelet membrane glycoprotein genes related to human platelet alloantigen (HPA)-1 to 17w.
Methods: The DNA segments of platelet membrane glycoprotein genes related to HPA-1 to 17w were amplified using author's designed primers. The amplification products were purified and directly sequenced to identify the HPA genotype and glycoprotein gene polymorphisms.
Results: Thirteen new single nucleotide polymorphisms (SNPs) and a micro-satellite sequence were found in the glycoprotein genes from the 112 random samples, in which two SNPs (1333G/A and 1960G/A) in ITGB3 gene result in two amino acid change (V419M and E628K) on glycoprotein GPIIIa.
Conclusion: New variants in platelet membrane glycoprotein genes were identified, which may lead to structure change of platelet membrane glycoprotein and affect the accuracy of partial HPA genotyping method.

The thrombolytic protease tissue plasminogen activator (tPA) is expressed in the CNS, where it regulates diverse functions including neuronal plasticity, neuroinflammation, and blood-brain-barrier integrity. However, its role in different brain regions such as the substantia nigra (SN) is largely unexplored. In this study, we characterize tPA expression, activity, and localization in the SN using a combination of retrograde tracing and β-galactosidase tPA reporter mice.

Background: Bok is a poorly characterized Bcl-2 protein family member with roles yet to be clearly defined. It is clear, however, that Bok binds strongly to inositol 1,4,5-trisphosphate (IP) receptors (IPRs), which govern the mobilization of Ca from the endoplasmic reticulum, a signaling pathway required for many cellular processes. Also known is that Bok has a highly conserved phosphorylation site for cAMP-dependent protein kinase at serine-8 (Ser-8).

Background: Hepatocellular carcinoma (HCC) genetic/transcriptomic signatures have been widely described. However, its proteomic characterization is incomplete. We performed non-targeted quantitative proteomics of HCC samples and explored its clinical, functional, and molecular consequences.

Cellular senescence (CS) is recognized as a critical driver of aging and age-related disorders. Recent studies have emphasized the roles of ion channels as key mediators of CS. Nonetheless, the roles and regulatory mechanisms of chloride intracellular channels (CLICs) during CS remain largely unexplored.

Transmembrane AMPA receptor regulatory proteins (TARPs) are claudin-like proteins that tightly regulate AMPA receptors (AMPARs) and are fundamental for excitatory neurotransmission. With cryo-electron microscopy (cryo-EM) we reconstruct the 36 kDa TARP subunit γ2 to 2.3 Å, which points to structural diversity among TARPs.
