Pancreatic cancer (PC) is a highly aggressive malignancy with a poor prognosis due to its late-stage diagnosis and limited treatment options.
This study aimed to elucidate the molecular mechanisms underlying PC progression and identify potential molecular targets for its diagnosis and treatment.
DAZAP1 expression in PC tissues, normal tissues and cell lines was assessed using immunohistochemistry (IHC), reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blotting. DAZAP1 knockdown was achieved through plasmid transfection, and its effects on ferroptosis and PC progression were evaluated using RT-qPCR, western blotting, CCK-8 assays, EdU staining, Fe content measurement, reactive oxygen species (ROS) detection, wound healing and Transwell migration assays.
DAZAP1 expression was significantly upregulated in PC tissues and cell lines compared to normal counterparts. DAZAP1 knockdown suppressed PC cell proliferation and induced ferroptosis, while ferroptosis inhibition reversed these effects, enhancing PC cell proliferation and metastasis.
DAZAP1 suppression promotes ferroptosis, thereby inhibiting PC cell proliferation and metastasis. These findings suggest that DAZAP1 is a potential therapeutic target for PC.
胰腺癌(PC)是一种侵袭性很强的恶性肿瘤,由于其晚期诊断和有限的治疗选择,预后较差。
本研究旨在阐明胰腺癌进展的分子机制,并确定其诊断和治疗的潜在分子靶点。
采用免疫组织化学(IHC)、逆转录定量聚合酶链反应(RT-qPCR)和蛋白质印迹法评估DAZAP1在胰腺癌组织、正常组织和细胞系中的表达。通过质粒转染实现DAZAP1基因敲低,并使用RT-qPCR、蛋白质印迹法、CCK-8法、EdU染色、铁含量测定、活性氧(ROS)检测、伤口愈合和Transwell迁移试验评估其对铁死亡和胰腺癌进展的影响。
与正常组织相比,DAZAP1在胰腺癌组织和细胞系中的表达显著上调。DAZAP1基因敲低抑制了胰腺癌细胞的增殖并诱导了铁死亡,而铁死亡抑制则逆转了这些作用,增强了胰腺癌细胞的增殖和转移。
抑制DAZAP1可促进铁死亡,从而抑制胰腺癌细胞的增殖和转移。这些发现表明DAZAP1是胰腺癌的一个潜在治疗靶点。
