Background

Fibroblast growth factors (FGFs) produce mitogenic and angiogenic effects in target cells by signaling through cell surface receptor tyrosine kinases. There are four members of the FGF receptor family: FGFR1 (flg), FGFR2 (bek, KGFR), FGFR3, and FGFR4. Each receptor contains an extracellular ligand binding domain, a transmembrane domain, and a cytoplasmic kinase domain (1). Following ligand binding and dimerization, the receptors are phosphorylated at specific tyrosine residues (2). Seven tyrosine residues in the cytoplasmic tail of FGFR1 can be phosphorylated: Tyr463, 583, 585, 653, 654, 730, and 766. Tyr653 and Tyr654 are important for catalytic activity of activated FGFR and are essential for signaling (3). The other phosphorylated tyrosine residues may provide docking sites for downstream signaling components such as Crk and PLCγ (4,5).

成纤维细胞生长因子 (FGFs)通过细胞表面的酪氨酸激酶受体传递信号,对靶细胞产生促有丝分裂和血管生成的效应。已知FGF受体家族有四个成员:FGFR-1 (flg), FGFR-2 (bek, KGFR), FGFR-3和FGFR-4。每个受体都有一个胞外配体结合区、跨膜区和一个胞内激酶区(1)。在结合配体和二聚化之后,受体的特定的酪氨酸位点发生磷酸化(2)。在FGFR-1的羧基端有7个酪氨酸位点能被磷酸化:Tyr463, 583, 585, 653, 654, 730和 766。Tyr653 和Tyr654对激活的FGFR的催化活性十分重要,对信号传导也是必要的(3)。其它的磷酸化酪氨酸位点能够为下游信号分子,如Crk 和PLCγ,提供结合位点(4,5)。

FGFR2 has several splicing isoforms, with ligand specificity largely determined by alternative splicing of exons 8 (IIIb) and 9 (IIIc). Alternative splicing is cell type specific, resulting in isoforms showing various tissue distribution and biological activities (6,7). Research studies have shown that mutations in the corresponding FGFR2 gene cause syndromes characterized by facial and limb defects, including LADD Syndrome, Crouzon Syndrome, Beare-Stevenson Cutis Gyrata Syndrome, Pfeiffer Syndrome, Apert Syndrome, and Jackson-Weiss Syndrome (8-10). Investigators have also observed mutations and altered expression of FGFR2 in cases of gastric, endometrial, and breast cancer (11).

FGFR2有一些剪接异构体,配体特异性主要是由选择性剪接的外显子8(IIIb)和9(IIIc)决定的。选择性剪接是细胞类型特异性的,从而导致亚型在各种组织中的分布和生物活性(6,7)。调查研究表明,在相应的FGFR2基因突变导致特点是面部及肢体的缺陷的综合征,包括拉德综合征,克鲁综合症,BEARE史蒂文森表皮Gyrata综合征,菲佛综合症,亚伯综合症和杰克逊 - 魏斯综合征(8-10)。调查还发现在胃,子宫内膜癌和乳腺癌中,FGFR2的突变和表达改变(11)。
