Does hMGB1 attenuate cardiac remodelling in the failing heart via enhanced cardiac regeneration and miR-206-mediated inhibition of TIMP-3?
HMGB1 injected into chronically failing hearts enhanced LV function and attenuated LV remodelling; these effects were associated with cardiac regeneration, increased collagenolytic activity, miR-206 overexpression and miR-206 -mediated inhibition of TIMP-3.
Serum levels of S100β were significantly higher in stroke patients than in nonvascular vertigo patients. Serum concentrations of MMP-9 tended to be higher in stroke patients, whereas no significant differences among groups were found for sVCAM-1 and GFAP. Receiver-operating characteristic analysis revealed a sensitivity of 94.4% and a specificity of 31.8% for detecting stroke in patients presenting with vertigo for S100β. S100β may serve as a biomarker for distinguishing between vertigo of vascular causes and nonvascular, acute vertigo.
