选择性剪接通过从单个基因产生多个mRNA来增加蛋白质组的复杂性。Affymetrix外显子阵列和体内或体外实验表明,选择性剪接受到机械应力的调节。机械生长因子(MGF)是胰岛素样生长因子1(IGF-1)和血管内皮生长因子(VEGF)剪接变体如VEGF 121、VEGF 165、VEGF 206、VEGF 189、VEGF 165和VEGF 145的剪接同种型,其表达受机械应力调节。然而,这一过程的机制尚不清楚。越来越多的证据表明其可能的机制与钙离子信号通路和磷酸化信号通路有关。本文综述了机械剪接调控的可能机制。这将有助于选择性剪接的生物力学研究。
Alternative splicing contributes to the complexity of proteome by producing multiple mRNAs from a single gene. Affymetrix exon arrays and experiments in vivo or in vitro demonstrated that alternative splicing was regulated by mechanical stress. Expression of mechano-growth factor (MGF) which is the splicing isoform of insulin-like growth factor 1(IGF-1) and vascular endothelial growth factor (VEGF) splicing variants such as VEGF121, VEGF165, VEGF206, VEGF189, VEGF165 and VEGF145 are regulated by mechanical stress. However, the mechanism of this process is not yet clear. Increasing evidences showed that the possible mechanism is related to Ca2+ signal pathway and phosphorylation signal pathway. This review proposes possible mechanisms of mechanical splicing regulation. This will contribute to the biomechanical study of alternative splicing.
