Description
Etoposideisaderivativeofepipodophyllotoxinthatactsasananticancerchemotherapeuticandimmunomodulatorycompound,inhibitingDNAtopoisomeraseIIandpreventingDNArepair.Inbreastcancercells,etoposideincreasesphosphorylationofp38MAPKandCHK2anddecreasesexpressionoffragilehistidintriad(FHIT),causingcelldeath.Inhepatomacells,etoposideinducesmixedmodesofprogrammedcelldeath,includingbothautophagyandapoptosis.Inleukemiacells,etoposideincreasestranscriptionofPKCδ.Etoposideisalsousedtotreathemophagocyticlymphohistiocytosis(HLH),inwhichitdecreasesreleaseofpro-inflammatorycytokinesandinhibitsactivatedTcells,increasingsurvivalrates.
