Title:TissueExpressionandLocalizationAnalysisoftheATF4GeneinFemaleReproductiveOrgans
Abstract:
TheATF4(activatingtranscriptionfactor4)gene,amemberoftheATF/cyclicAMPresponsiveelementbinding(CREB)family,playsanimportantroleincellularstressresponseandregulationofgeneexpression.However,littleisknownaboutitstissueexpressionandlocalizationinfemalereproductiveorgans.ThisstudyaimedtoinvestigatetheexpressionpatternandsubcellularlocalizationofATF4invariousfemalereproductivetissues,includingtheovary,uterus,andcervix.ImmunohistochemicalanalysiswasperformedtodeterminethedistributionofATF4inthesetissues.ThefindingsshedlightonthepotentialroleofATF4infemalereproductionandmayhaveimplicationsforunderstandingreproductivedisorders.

Methods:
Tissuesamplesfromtheovary,uterus,andcervixwerecollectedfromfemalerats.ImmunohistochemicalanalysiswasperformedtodetectATF4expressioninthesetissues.Briefly,tissuesectionswereincubatedwithaprimaryantibodyagainstATF4,followedbyasecondaryantibodyconjugatedwithafluorescentdye.Thesectionswerethenvisualizedunderafluorescencemicroscope.ImageanalysissoftwarewasusedtoquantifyATF4expressionlevels.
Results:
