KIF26B(Kinesin family member 26B)是驱动蛋白家族中的一员,驱动蛋白是一种在细胞内负责细胞器运输、细胞分裂和细胞骨架组织的马达蛋白。KIF26B在细胞内运输中发挥重要作用,其表达和功能失调与多种疾病的发生发展相关。
研究表明,KIF26B的表达和功能失调与多种疾病的发生发展相关。在创伤后异位骨化(HO)的形成中,KIF26B的表达水平与HO的严重程度相关。研究发现,KIF26B的缺失可以抑制BMP2诱导的Runx2、Sp7/Osterix、Col1A1、Alp和Bglap/Osteocalcin的表达以及矿化结节的形成,同时抑制ERK MAP激酶的激活,增强p38和SMAD 1/5/8的磷酸化[1]。这些结果表明,KIF26B在调节创伤后异位骨化的严重程度中发挥重要作用。
此外,KIF26B还与圆锥角膜(KTCN)的发生相关。研究发现,KIF26B的基因多态性rs2228557C/T和rs12407427C/T与KTCN的易感性增加相关[2]。这表明KIF26B在圆锥角膜的发生发展中发挥重要作用。
KIF26B还在肾脏发育中发挥重要作用。研究发现,KIF26B是Sall1的下游靶点,其基因的缺失会导致肾脏发育不全,因为Sall1的功能受损,导致输尿管芽对间充质细胞的吸引作用受损[3]。此外,KIF26B的过表达可以增强细胞粘附,通过与非肌肉肌球蛋白相互作用,从而在肾脏发育中发挥重要作用。
KIF26B还与精神分裂症和乳腺癌的易感性相关。研究发现,KIF26B的基因多态性rs12407427 T/C与精神分裂症和乳腺癌的易感性增加相关[4]。这表明KIF26B在精神分裂症和乳腺癌的发生发展中发挥重要作用。
KIF26B还与微塑料引起的肺损伤相关。研究发现,circ_kif26b可以与miR-346-3p结合,共同调节p21的表达,从而影响肺泡上皮细胞的衰老和微塑料引起的肺损伤[5]。
KIF26B在结肠癌的发生发展中发挥重要作用。研究发现,KIF26B的表达水平与结肠癌的预后不良和肿瘤免疫浸润相关。KIF26B的表达水平与免疫相关基因、肿瘤免疫浸润和免疫细胞生物标志物基因的表达相关[6]。
KIF26B还与肾脏纤维化的进展相关。研究发现,KIF26B的缺失可以保护肾脏免受腺嘌呤诱导的肾脏纤维化,降低肾脏组织中结缔组织生长因子(CTGF)和肌成纤维细胞的积累[7]。
KIF26B还与异位钙化相关。研究发现,KIF26B的缺失可以抑制祖细胞/干细胞的成骨分化,并抑制异位钙化[8]。
KIF26B还与胃癌的发生发展相关。研究发现,KIF26B的表达水平与胃癌的预后不良相关。KIF26B通过激活VEGF信号通路促进胃癌细胞的增殖和转移[9]。
KIF26B还与非小细胞肺癌的发生发展相关。研究发现,KIF26B的表达水平与非小细胞肺癌的预后不良相关。KIF26B的缺失可以抑制非小细胞肺癌细胞的增殖、侵袭和上皮间质转化,并增强化疗敏感性[10]。
综上所述,KIF26B在多种疾病的发生发展中发挥重要作用,包括创伤后异位骨化、圆锥角膜、肾脏发育、精神分裂症、乳腺癌、微塑料引起的肺损伤、结肠癌、肾脏纤维化、异位钙化和胃癌。KIF26B的表达和功能失调与多种疾病的预后不良相关,提示KIF26B可能是治疗这些疾病的重要靶点。
