食欲素A及其受体与外周器官和中枢神经系统的许多生理过程相关,在一系列人类疾病中发挥着重要作用,包括嗜睡病、肥胖症、药物成瘾等。越来越多的证据表明,食欲素-A 和 OX1 受体 (OX1R) 在恶性肿瘤中高表达,这表明 OX1R 的刺激可能对于肿瘤发生至关重要。在这里,我们试图阐明胰腺癌中食欲素 A 表达与恶性肿瘤之间的相关性。我们的结果表明,刺激 OX1R 可促进胰腺癌 PANC1 细胞的细胞增殖。此外,orexin-A治疗可以保护PANC1细胞免于凋亡,而抑制OX1R的刺激则通过调节关键凋亡因子Bcl-2、caspase-9和c-myc的胰腺癌细胞表达水平导致细胞凋亡。进一步研究表明,orexin-A 治疗可激活 Akt/mTOR 信号通路,通过抑制 Bcl-2/caspase-9/c-myc 介导的胰腺癌细胞凋亡来促进细胞增殖。我们的研究结果表明,OX1R 的刺激可能对胰腺癌的肿瘤发生很重要,并且是治疗胰腺癌患者的潜在靶点。
The orexin-A and its receptors are associated with many physiological processes in peripheral organs and the central nervous system and play important roles in a series of human diseases, including narcolepsy, obesity, and drug addiction. Increasing evidence has indicated high expression of orexin-A and OX1 receptor (OX1R) in malignant tumors, suggesting that the stimulation of OX1R might be essential for tumorigenesis. Here, we attempted to clarify the correlation between orexin-A expression and malignancy in pancreatic cancer. Our results indicated that the stimulation of OX1R promotes cell proliferation in pancreatic cancer PANC1 cells. Additionally, orexin-A treatment can protect PANC1 cells from apoptosis, whereas inhibition of the stimulation of OX1R results in apoptosis through regulating pancreatic cancer cell expression levels of Bcl-2, caspase-9, and c-myc, which are key apoptotic factors. Further investigation revealed that orexin-A treatment activates theAkt/mTOR signaling pathway to promote cell proliferation byinhibiting Bcl-2/caspase-9/c-myc-mediated apoptosis in pancreatic cancer cells. Our findings revealed that the stimulation of OX1R might be important for tumorigenesis in pancreatic cancer and is a potential target for the treatment of patients with pancreatic cancer.
