In angiosperms xyloglucan endotransglucosylase (XET)/hydrolase (XTH) is involved in reorganization of the cell wall during growth and development. The location of oligo-xyloglucan transglucosylation activity and the presence of XTH expressed sequence tags (ESTs) in the earliest diverging extant plants, i.e. in bryophytes and algae, down to the Phaeophyta was examined. The results provide information on the presence of an XET growth mechanism in bryophytes and algae and contribute to the understanding of the evolution of cell wall elongation in general.

    J Tissue Eng Regen Med (2013) PMID 23653421

    We sought to analyse the osteogenic gene expression profile of whole T cells, CD4 and CD8 T cells isolated from healthy donors and investigated whether secreted factors from each group modulate osteogenic differentiation of human MSCs. Gene expression profiling identified a pool of 51 genes involved...

  2. A novel c.-274C>G polymorphism in bovine SIRT1 gene contributes to diminished promoter activity and is associated with increased body size.

    We screened and identified a novel polymorphism (c.-274C>G) in the SIRT1 promoter region. In silico prediction reveals that this SNP is in the core of cell cycle-dependent element (CDE)-binding motif. Interestingly, the G allele abolished a CDE-binding site, which suggested its functional significan...

    We found that full-length Hsp70 on its own could activate the Hsp104 hexamer by promoting intersubunit coordination, suggesting that Hsp70 is an activator of the Hsp104 motor....
