AREG(Amphiregulin)属于表皮生长因子(EGF)家族,是一种分泌型糖蛋白,通过与表皮生长因子受体(EGFR)结合发挥作用。它在细胞增殖、分化、组织修复和免疫调节中起关键作用,尤其在皮肤、肺和乳腺等上皮组织中表达较高。AREG通过激活EGFR下游的MAPK和PI3K/AKT信号通路,促进细胞生长和组织再生。在伤口愈合过程中,AREG由免疫细胞(如T细胞和巨噬细胞)分泌,刺激角质形成细胞迁移和增殖。AREG的突变或异常表达可能导致功能失调,例如某些突变会降低其与EGFR的结合能力,从而削弱其促增殖作用。AREG过表达与多种癌症相关,包括乳腺癌、肺癌和结直肠癌,因为它持续激活EGFR信号通路,促进肿瘤生长和转移。相反,AREG表达降低可能影响组织修复能力,导致伤口愈合延迟或上皮屏障功能受损。在炎症性疾病(如哮喘和炎症性肠病)中,AREG通过调节免疫细胞活性和上皮细胞反应参与疾病进程。AREG还与妊娠相关,在胚胎植入和胎盘发育中发挥作用。AREG的基因家族(EGF家族)成员通常含有EGF样结构域,能够激活EGFR家族受体,参与细胞通讯和组织稳态。家族成员(如EGF、TGF-α和HB-EGF)在功能上有重叠,但也具有组织特异性作用。AREG的独特之处在于其双向调节能力,既能促进增殖,也能在某些情况下抑制过度生长。研究AREG有助于开发针对癌症和炎症性疾病的靶向治疗策略。

The protein encoded by this gene is a member of the epidermal growth factor family. It is an autocrine growth factor as well as a mitogen for astrocytes, Schwann cells and fibroblasts. It is related to epidermal growth factor (EGF) and transforming growth factor alpha (TGF-alpha). The protein interacts with the EGF/TGF-alpha receptor to promote the growth of normal epithelial cells, and it inhibits the growth of certain aggressive carcinoma cell lines. It also functions in mammary gland, oocyte and bone tissue development. This gene is associated with a psoriasis-like skin phenotype, and is also associated with other pathological disorders, including various types of cancers and inflammatory conditions.

由该基因编码的蛋白是表皮生长因子家族的一个成员。它是一种自分泌生长因子,以及为星形胶质细胞,施万细胞和成纤维细胞有丝分裂原。它是涉及表皮生长因子(EGF)和转化生长因子α(TGF-α)。该蛋白质与EGF / TG??F-α受体促进正常上皮细胞的生长交互,它抑制某些侵袭性癌细胞系的生长。它还可以在乳腺,卵母细胞和骨组织的发展。该基因与银屑病样皮肤的表型相关联,并且还与其他的病理病症,包括各种癌症和炎性病症的关联。 [由RefSeq的,2014年4月提供]
