Title：RoleandmolecularmechanismofE2F6instress-inducedcellapoptosis

Introduction:

Cellapoptosisisanimportantprocessinmaintainingtissuehomeostasisandplaysacrucialroleindevelopment,immunity,anddisease.Stress-inducedapoptosisisacommonformofcelldeathtriggeredbyvariousstressfactorssuchasoxidativestress,DNAdamage,andinflammation.

E2F6isamemberoftheE2Ffamilyoftranscriptionfactors,whichplayimportantrolesinregulatingcellproliferation,differentiation,andapoptosis.However,theroleofE2F6instress-inducedapoptosisandtheunderlyingmolecularmechanismsremainlargelyunclear.

Objective:

ThemainobjectiveofthisstudyistoinvestigatetheroleandmolecularmechanismofE2F6instress-inducedapoptosis.Specifically,weaimto:

1.InvestigatetheexpressionlevelandsubcellularlocalizationofE2F6instress-inducedapoptosis.

2.InvestigatetheeffectofE2F6knockdownoroverexpressiononstress-inducedapoptosis.

3.IdentifythedownstreamtargetgenesregulatedbyE2F6duringstress-inducedapoptosis.

Methodology:

Cellculture:Thehumanembryonickidney(HEK293)celllinewillbeculturedandmaintainedinDMEMcontaining10%fetalbovineserumand1%penicillin/streptomycinat37°Cwith5%CO2.

Stressinduction:Thecellswillbesubjectedtostressinductionwithhydrogenperoxide,UVradiation,oretoposidetreatment.

E2F6knockdownandoverexpression:E2F6willbeknockeddownusingsmallinterferingRNA(siRNA)andoverexpressedusingplasmidtransfection.

Cellapoptosisassay:ApoptosiswillbemeasuredbyflowcytometryandCaspase-3activityassay.

RNAsequencingandbioinformaticsanalysis:RNAwillbeextractedfromcellsandsequencedusingnext-generationsequencing.BioinformaticsanalysiswillbeperformedtoidentifydifferentiallyexpressedgenesandE2F6targetgenes.
