Brain pericytes are important to maintain vascular integrity of the neurovascular
unit under both physiological and ischemic conditions. Ischemic stroke is known
to induce an inflammatory and hypoxic response due to the lack of oxygen and
glucose in the brain tissue. How this early response to ischemia is molecularly
regulated in pericytes is largely unknown and may be of importance for future
therapeutic targets. Here we evaluate the transcriptional responses in in vitro
cultured human brain pericytes after oxygen and/or glucose deprivation. Hypoxia
has been widely known to stabilise the transcription factor hypoxia inducible
factor 1-alpha (HIF1?) and mediate the induction of hypoxic transcriptional
programs after ischemia. However, we find that the transcription factors Jun
Proto-Oncogene (c-JUN), Nuclear Factor Of Kappa Light Polypeptide Gene Enhancer
In B-Cells (NF?B) and signal transducer and activator of transcription 3 (STAT3)
bind genes regulated after 2hours (hs) of omitted glucose and oxygen before
HIF1?. Potent HIF1? responses require 6hs of hypoxia to substantiate
transcriptional regulation comparable to either c-JUN or STAT3. Phosphorylated
STAT3 protein is at its highest after 5 min of oxygen and glucose (OGD)
deprivation, whereas maximum HIF1? stabilisation requires 120 min. We show that
STAT3 regulates angiogenic and metabolic pathways before HIF1?, suggesting that
HIF1? is not the initiating trans-acting factor in the response of pericytes to
ischemia.
