Plasma interleukin-6 (IL-6) level correlates with patient survival in colorectal carcinoma and is regarded as a prognostic factor. In this study, the role of IL-6 in colorectal carcinoma proliferation, chemotaxis and invasion was investigated.
Proliferation and invasion were measured in four colorectal carcinoma cell lines. The effect of IL-6 (10, 50, 100 ng/ml) on progression (the ability to grow, adhere, chemotax and invade) was also measured.
Physiological (10 ng/ml) and pharmacological (50 and 100 ng/ml) concentrations of IL-6 did not significantly affect growth. However, IL-6 (10 ng/ml) significantly increased attachment to basement membrane (p < 0.05). IL-6 (50 ng/ml) significantly increased the chemotaxis, anchorage-independent growth and invasiveness of SW-480 (one of the four cell lines) (p < 0.05). IL-6 (100 ng/ml) resulted in negative feedback inhibition of these effects.
IL-6 plays an important role in the progression of colorectal carcinoma.
血浆白细胞介素-6(IL-6)水平与结直肠癌患者的生存率相关,被视为一种预后因素。在本研究中,对IL-6在结直肠癌增殖、趋化性和侵袭中的作用进行了研究。
在四种结直肠癌细胞系中检测增殖和侵袭情况。还检测了IL-6(10、50、100 ng/ml)对进展(生长、黏附、趋化和侵袭能力)的影响。
生理浓度(10 ng/ml)和药理浓度(50和100 ng/ml)的IL-6对生长无显著影响。然而,IL-6(10 ng/ml)显著增加了对基底膜的黏附(p < 0.05)。IL-6(50 ng/ml)显著增加了SW-480(四种细胞系之一)的趋化性、非锚定依赖性生长和侵袭性(p < 0.05)。IL-6(100 ng/ml)导致这些效应的负反馈抑制。
IL-6在结直肠癌进展中起重要作用。
