Unusually high incidence of polyomavirus JC infection in the higher grade of colorectal cancer tissues in Taiwan.

Introduction: The human JC polyomavirus (JCPyV) has been detected in colorectal cancer (CRC) tissues and is suggested to contribute to CRC tumorigenesis. The rearrangement of the JCPyV regulatory region is supposedly associated with CRC development. The progression of CRC involves the stepwise accumulation of mutations.

GSK3β‑mediated Ser156 phosphorylation modulates a BH3‑like domain in BCL2L12 during TMZ‑induced apoptosis and autophagy in glioma cells.

BH3 domains, classified initially as BCL2 homology domains, participate in both apoptosis and autophagy. Beclin‑1 contains a BH3 domain, which is required for binding to antiapoptotic BCL2 homologs and BCL2‑mediated inhibition of autophagy. BCL2‑like 12 (BCL2L12) also harbors a BH3‑like domain, which is 12 residues long and contains a LXXXAE/D motif.

The origin of GSKIP, a multifaceted regulatory factor in the mammalian Wnt pathway.

GSK3β interacting protein (GSKIP) is a naturally occurring negative regulator of GSK3β and retains both the Protein Kinase A Regulatory subunit binding (PKA-RII) domain and GSK3β interacting domain. Of these two domains, we found that PKA-RII is required for forming a working complex comprising PKA/GSKIP/GSK3β/Drp1 to influence phosphorylation of Drp1 Ser637. In this study, bioinformatics and experimental explorations re-analyzing GSKIP's biofunctions suggest that the evolutionarily conserved Domain of Unknown Function (DUF727) is an ancestral prototype of GSKIP in prokaryotes, and acquired the C-terminal GSK3β binding site (tail) in invertebrates except for Saccharomyces spp.
