Uterine cervical carcinoma (UCC) is one of the most common malignant tumors in females, and UCC has a close relationship with chronic cervicitis. As the endogenous "braking signal," lipoxins can regulate anti-inflammation and the resolution of inflammation. We investigated the effect of lipoxin A4 (LXA4) on the proliferation, apoptosis, and migration in lipopolysaccharide (LPS)-stimulated Hela cells. We demonstrated that LXA4 could significantly suppress p53, cyclin D1 expression, and migration of LPS-stimulated Hela cells via nuclear factor-κB (NF-κB) pathway, and these effects could be blocked by Boc-2, the specific inhibitor of FPR2/ALX (the receptor of LXA4). We presented evidence for a novel role of LXA4 on the proliferation and migration in LPS-stimulated Hela cells, and FPR2/ALX was involved in the procedures. These results showed that LXA4 could be a possible candidate for UCC therapy, and blocking the activation of NF-κB would be an effective drug target.
子宫颈癌(UCC)是女性最常见的恶性肿瘤之一,UCC 与慢性宫颈炎密切相关。脂氧素作为内源性“制动信号”,可以调节抗炎和炎症消退。我们研究了脂氧素 A4(LXA4)对脂多糖(LPS)刺激的 Hela 细胞增殖、凋亡和迁移的影响。结果表明,LXA4 可以通过核因子-κB(NF-κB)通路显著抑制 LPS 刺激的 Hela 细胞中 p53、细胞周期蛋白 D1 的表达和迁移,而 Boc-2(FPR2/ALX 的特异性抑制剂)可以阻断这些作用。FPR2/ALX 参与了 LPS 刺激的 Hela 细胞中 LXA4 的增殖和迁移的新作用。这些结果表明,LXA4 可能是 UCC 治疗的候选药物,而阻断 NF-κB 的激活可能是一种有效的药物靶点。
