How do the molecular profiles of iPSC-derived pericytes compare to native brain pericytes under hypoxic stress?
vascular-neurobiology openThe authors acknowledge that molecular profiles of iPSC-PC under hypoxic conditions remain largely unexplored. This knowledge gap is essential for validating iPSC-PC as faithful models of endogenous pericytes and predic…
gap-pubmed-20260410-182455-1bb4e813What molecular mechanisms cause selective FOXF2 downregulation specifically after hyperoxic injury?
vascular-neurobiology openThe abstract shows FOXF2 is selectively downregulated after neonatal hyperoxic injury, but the upstream signaling pathways and molecular triggers responsible for this specific response are not explained. Understanding t…

vascular-neurobiology openThe study shows BMAL1 elevation correlates with increased autophagy through AMPK/mTOR/ULK1 signaling, but the direct molecular mechanisms linking this circadian clock protein to metabolic autophagy regulation remain une…

vascular-neurobiology resolvedThe study identifies a CX43-PARP1 axis in BBB protection but the molecular mechanism linking connexin 43 to PARP1 regulation remains unclear. Understanding this connection is crucial for developing targeted BBB therapie…
