摘要
Helicobacter pylori(H.pylori)is a major etiological factor in the development of gastric cancer.Large-scale epidemiological studies have confirmed the strong association between H.pylori infection and both cancer development and progression.Interleukin-8(IL-8)is overexpressed in gastric mucosa exposed to H.pylori.The expression of IL-8 directly correlates with a poor prognosis in gastric cancer.IL-8 is multifunctional.In addition to its potent chemotactic activity,it can induce proliferation and migration of cancer cells.In this review,we focus on recent insights into the mechanisms of IL-8 signaling associated with gastric cancer.The relationship between IL-8 and H.pylori is discussed.We also summarize the current therapeutics against IL-8 in gastric cancer.
Helicobacter pylori (H. pylori) is a major etiological factor in the development of gastric cancer. Large-scale epidemiological studies have confirmed the strong association between H. pylori infection and both cancer development and progression. Interleukin-8 (IL-8) is overexpressed in gastric mucosa exposed to H. pylori. The expression of IL-8 directly correlates with a poor prognosis in gastric cancer. IL-8 is multifunctional. In addition to its potent chemotactic activity, it can induce proliferation and migration of cancer cells. In this review, we focus on recent insights into the mechanisms of IL-8 signaling associated with gastric cancer. The relationship between IL-8 and H. pylori is discussed. We also summarize the current therapeutics against IL-8 in gastric cancer.
