BrainSci. 2017,7, 14 particular setofgeneregulation features (namedpertubagens)was likely tobeconnectedwith the genes listed in theLINCSreport. Positivereadings in theConsensusKnockdownConnections in the report indicate thatknockdownof thegenes listed in theLINCSreportwouldmatch thegenechanges input into theQueryApp,andthus thegeneswithhighscores representpotential targetgenes for the experimental treatment. 3.Results 3.1. ExpressionProfile of Inflammasome-RelatedGenesFollowinganLPSChallenge,withandwithout MorphineTolerance Alterations ingeneexpressionweremeasured in rats challengedwithLPS,withandwithout morphine tolerance, using a PCR array containing 84 genes related to inflammasome activation and function. NLRP12 expression was significantly decreased in response to LPS in both the morphine-tolerant (morphine-tolerant+LPS)andcontrol (placebo-control+LPS)rats, comparedtothe ratsgivensaline(morphine-tolerant+salineandplacebo-control+saline) (Figure1,Table1).However, thedecreasewasgreater in theplacebo-control rats (−7.3 fold;p<0.01) than in themorphine-tolerant rats (−4.5 fold;p<0.05).
