  11. Annealing helicase HARP closes RPA-stabilized DNA bubbles non-processively. PMID: 28334870
  12. Neural precursor cell (NPC):glioma cell communication underpins the propensity of glioma to colonize the lateral ventricle subventricular zone (SVZ) through secretion of chemoattractant signals toward which glioma cells home; analyses of SVZ NPC-secreted factors revealed the neurite outgrowth-promoting factor pleiotrophin, with required SPARC/SPARCL1 and HSP90B as mediators of this chemoattractant effect. PMID: 28823557
  13. these data indicate that PTN-PTPRZ-A signaling controls the timing of oligodendrocyte precursor cell differentiation in vivo, in which the CS moiety of PTPRZ receptors maintains them in a monomeric active state until its ligand binding. PMID: 27445335
