TNF（tumor necrosis factor），癌症关联基因，基因ID：7124，该基因编码一种多功能促炎细胞因子，属于肿瘤坏死因子（TNF）超家族。这种细胞因子主要由巨噬细胞分泌。它能与受体TNFRSF1A/TNFR1和TNFRSF1B/TNFBR结合并通过其发挥作用。这种细胞因子参与调节广泛的生物学过程，包括细胞增殖、分化、凋亡、脂质代谢和凝血。这种细胞因子与多种疾病有关，包括自身免疫性疾病、胰岛素抵抗和癌症。小鼠的基因敲除研究也表明了这种细胞因子的神经保护作用。[由RefSeq提供，2008年7月]This gene encodes a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (TNF) superfamily. This cytokine is mainly secreted by macrophages. It can bind to， and thus functions through its receptors TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. This cytokine is involved in the regulation of a wide spectrum of biological processes including cell proliferation， differentiation， apoptosis， lipid metabolism， and coagulation. This cytokine has been implicated in a variety of diseases， including autoimmune diseases， insulin resistance， and cancer. Knockout studies in mice also suggested the neuroprotective function of this cytokine. [provided by RefSeq， Jul 2008]。
