成纤维细胞生长因子 FGF(Fibroblast Growth Factors,FGFs)最初是以其成纤维细胞的有丝分裂能力命名的。 FGF及其受体在动物界高度保守。 在哺乳动物中, FGF家族 包括23种多肽,它们调节多种细胞的迁移、增殖、分化、存活、代谢活动和神经功能。 FGF家族成员. FGF家族至少有20个成员,命名为FGF-1到FGF-20,但 酸性FGF 和 碱性FGF 是FGF-1和FGF-2的常用名称,而 角质形成细胞生长因子 (KGF)是FGF-7的常用名称。 酸性FGF(aFGF)和碱 …
Roles of the FGF-FGFR Signaling System in Cancer Development …
In mammals, there are 22 members of the FGF family and four high affinity, cell surface localized FGF receptors (FGFR1–4) with tyrosine kinase activity. Most FGFs act in a paracrine or autocrine manner and are referred to as canonical FGFs.
FGFR通路与肿瘤 - 知乎 - 知乎专栏
成纤维细胞生长因子 (fibroblast growth factors,FGFs)结合其受体(fibroblast growth factor receptors,FGFRs) ,激活其调控的下游信号通路,在 促分裂 (胚胎发生、生长发育等)和 非促分裂 (神经调节、代谢调节等)等生物学过程中起着重要作用。 其中 促分裂通路中,FGFR的高表达、突变等导致其信号通路异常激活,FGFR通路 促分裂作用不受控制,则肿瘤随之产生。 因此若肿瘤因FGFR高表达或者基因突变导致,则 可以通过抑制FGFR通路的促分裂作用就可以 …
FGF/FGFR-Dependent Molecular Mechanisms Underlying Anti …
Activation of FGFR1 induces hyaluronan (HA) synthesis via STAT3 pathway and causes accumulation of HA in extracellular matrix (ECM) of breast cancer cells . Inhibition of HA synthesis and/or accumulation by STAT3 inhibition reduces cell migration and proliferation, and partially reverses resistance to doxorubicin [ 96 ].
The FGF family: biology, pathophysiology and therapy - PMC
Although fibroblast homologous factors (FHFs) have high sequence and structural homology with fibroblast growth factors (FGFs) and bind heparin with high affinity, they do not activate FGF receptors (FGFRs). The FHF core structure is similar to that of FGFs: they exhibit the same β-trefoil core that consists of 12 antiparallel β-strands.
Fibroblast growth factor receptor - Wikipedia
The fibroblast growth factor receptors (FGFR) are, as their name implies, receptors that bind to members of the fibroblast growth factor (FGF) family of proteins. Some of these receptors are involved in pathological conditions. For example, a point …
关于成纤维生长因子之bFGF - 知乎 - 知乎专栏
成纤维细胞生长因子 (fibroblast growth factors, FGFs) 是一个结构相关的22种多肽家族,发现之初因其能促进成纤维细胞增殖,故命名为成纤维细胞生长因子。 其特征是对 糖胺聚糖 肝素结合位点具有亲和力。 在脊椎动物中,FGF家族的22个成员的分子量在17-34kDa之间,氨基酸同源性为13%-71%。 在脊椎动物物种中,FGFs在基因结构和氨基酸序列上都高度保守。 FGF对硫酸肝素蛋白聚糖具有高亲和力,需要 硫酸乙酰肝素 来激活四种细胞表面FGF受体之一。 在胚胎发育过 …
成纤维细胞生长因子受体(FGFR)临床意义及检测 - 雪球
2024年6月20日 · FGFR,全称是成纤维细胞生长因子受体(Fibroblast Growth Factor Receptor),与EGFR同属于受体酪氨酸激酶(RTKs)家族。 FGFR家族至少有28个不同的成员,主要分布于上皮或内皮细胞,主要包括 FGFR1、FGFR2、FGFR3和FGFR4 四种亚型,各亚型均具有与配体结合的胞外区、跨膜区和受体磷酸化的胞内区的结构特点。 FGFR分子改变可导致异常FGF/FGFR信号,促使细胞增殖、新血管生成、侵袭、转移、抗凋亡等,这与广泛的人类恶 …

Refer to the table below the pathway to see the reported receptor binding specificities for the different FGF ligands, their physiological functions, and the pathologies associated with mutations or amplification of different FGFs.
FGF/FGFR signaling in health and disease - PubMed
2020年9月2日 · Growing evidences suggest that the fibroblast growth factor/FGF receptor (FGF/FGFR) signaling has crucial roles in a multitude of processes during embryonic development and adult homeostasis by regulating cellular lineage commitment, differentiation, proliferation, and apoptosis of various types of cells.
