Cervical cancer is the fourth-most common type of cancer in the world that causes death in women. It is mainly caused by persistent infection by human papillomavirus (HPV) that triggers a chronic inflammatory process. Therefore, the use of anti-inflammatory drugs is a potential treatment option. The effects of piperine, an amino alkaloid derived from , are poorly understood in cervical cancer inflammation, making it a target of research. This work aimed to investigate the antitumor effect of piperine on cervical cancer and to determine whether this effect is modulated by the cyclooxygenase 2 (PTGS2) pathway using in vitro model of cervical cancer (HeLa, SiHa, CaSki), and non-tumoral (HaCaT) cell lines. The results showed that piperine reduces in vitro parameters associated with neoplastic evolution such as proliferation, viability and migration by cell cycle arrest in the G1/G0 and G2/M phases, with subsequent induction of apoptosis. This action was modulated by downregulation of cyclooxygenase 2 (PTGS2) pathway, which in turn regulates the secretion of cytokines and the expression of mitogen-activated protein kinases (MAPKs), metalloproteinases (MMPs), and their antagonists (TIMPs). These findings indicate the phytotherapeutic potential of piperine as complementary treatment in cervical cancer.
宫颈癌是全球导致女性死亡的第四大常见癌症类型。它主要由人乳头瘤病毒(HPV)持续感染引发慢性炎症过程所致。因此,使用抗炎药物是一种潜在的治疗选择。胡椒碱是一种源自[此处原文缺失相关来源信息]的氨基生物碱,其在宫颈癌炎症中的作用尚不清楚,这使其成为研究对象。本研究旨在利用宫颈癌体外模型(HeLa、SiHa、CaSki)和非肿瘤(HaCaT)细胞系,研究胡椒碱对宫颈癌的抗肿瘤作用,并确定这种作用是否由环氧合酶2(PTGS2)途径介导。结果表明,胡椒碱通过使细胞周期停滞在G1/G0和G2/M期,降低与肿瘤进展相关的体外参数,如增殖、活力和迁移,随后诱导细胞凋亡。这种作用通过下调环氧合酶2(PTGS2)途径来调节,该途径进而调节细胞因子的分泌以及丝裂原活化蛋白激酶(MAPKs)、金属蛋白酶(MMPs)及其拮抗剂(TIMPs)的表达。这些发现表明胡椒碱作为宫颈癌辅助治疗具有植物治疗潜力。
