摘要:
Background:Caffeic acid(CA)is considered a promising phytochemical that has inhibited numerous cancer cell ***,it is gaining increasing attention due to its safe and pharmacological *** this study,we investigated the role of CA in inhibiting the Interleukin-6(IL-6)/Janus kinase(JAK)/Signal transducer and activator of transcription-3(STAT-3)mediated suppression of the proliferation signaling in human prostate cancer *** and Methods:The role of CA in proliferation and colony formation abilities was studied using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide(MTT)assay and colony formation *** cell death and cell cycle arrest were identified usingflow cytometry *** treatment-associated protein expression of mitogen-activated protein kinase(MAPK)families,IL-6/JAK/STAT-3,proliferation,and apoptosis protein expressions in PC-3 and LNCaP cell lines were measured using Western blot ***:We have obtained that treatment with CA inhibits prostate cancer cells(PC-3 and LNCaP)proliferation and induces reactive oxygen species(ROS),cell cycle arrest,and apoptosis cell death in a concentration-dependent ***,CA treatment alleviates the expression phosphorylated form of MAPK families,i.e.,extracellular signal-regulated kinase 1(ERK1),c-Jun N-terminal kinase(JNK),and p38 in PC-3 ***-6 mediated JAK/STAT3 expressions regulate the proliferation and antiapoptosis that leads to prostate cancer metastasis and ***,to mitigate the expression of IL-6/JAK/STAT-3 is considered an important target for the treatment of prostate *** this study,we have observed that CA inhibits the expression of IL-6,JAK1,and phosphorylated STAT-3 in both PC-3 and LNCaP *** to the inhibitory effect of IL-6/JAK/STAT-3,it resulted in decreased expression of cyclin-D1,cyclin-D2,and CDK1 in both PC-3 *** addition,CA induces apoptosis by enhancing the expression of Bax and caspas
