We also analyzed expressoof GFAP, Nestn, GLAST and GLT one.Remedy wth JAK nhbtor decreased levels of GFAand GLAST, and ncreased ranges of Nestn,et GLT one amounts have been smar to untreated cultures.To determne f glutamate uptake was also impacted by JAK nhbtor treatment method, we performed a D aspartate uptake assay oJAK nhbtor handled astrocytes.JAK nhbtor decreased total uptake as well as noGLT one uptake, but GLT one specfc uptake was unaffected.These experments were also carried out the absence of Na to determne the contrbutoof noNa dependent uptake to your total uptake measured and ths accounted for less tha1% of your total uptake.Our final results ndcate that dsruptoof JAK STAT sgnalng prmary astrocytes s causally lnked to a reduce glutamate transporter functothese cells.Pharmacologcal their explanation nhbtoof JAK STAT sgnalng vvo decreases GLAST expressothe whte matter To determne whether nhbtoof JAK STAT sgnalng vvo also decreases GLAST expresson, we treated pernatal mce thathave not beeexposed tohypoxa wth the JAK STAT nhbtor AG490 from P6 P11.
thas beeprevously demonstrated that admnstratoof AG490 impacts JAK STAT sgnalng the bran.Just after inhibitor screening AG490 admnstraton, ranges of pJAK1, pJAK2, pSTAT3 have been sgnfcantly decreased P11 whte matter lysates as compared wth untreated anmals confrmng the pharmacologcal treatment nhbted JAK STAT sgnalng vvo.The two GFAand GLAST expressowere also proportonally diminished.Conversely, amounts of JAK1, JAK2, STAT3 and GLT 1 have been not affected.We also noted that Nestlevels were not modfed, as observed both whte matter of mce exposed tohypoxa and prmary astrocyte cultures treated wth JAK nhbtor .These vvo final results help our observatothat GLAST expressos decreased prmary astrocyte cultures exposed to JAK nhbtor and, whe regulatoof GLAST and GLT 1 s complex, our data ndcate that JAK STAT sgnalng plays a part GLAST expresson.DSCUSSOThe cellular responses tohypoxa nduced dffuse whte matter njury are stl largely unknown.
