Abstract

RNA alternative splicing represents a pivotal regulatory mechanism of eukaryotic gene expression, wherein splicing factors (SFs) serve as key regulators. Aberrant SF expression drives oncogenic splice variant production, thereby promoting tumorigenesis and malignant progression. However, the biological functions and potential targets of SFs remain largely underexplored. Through multi-omics analysis, we identified survival-related splicing factors (SFs) in esophageal cancer and elucidated their biological regulatory networks. To further investigate their downstream splicing targets, we combined alternative splicing events resulting from SF knockdown with those specific to esophageal cancer. Finally, these splicing events were validated through full-length RNA sequencing and confirmed in cancer cells and clinical specimens. We identified six SFs that are highly expressed in esophageal cancer and correlate with poor prognosis. Further analysis revealed that these factors are significantly associated with immune infiltration, cancer stemness, tumor heterogeneity, and drug resistance. was identified as a hub SFs. The target genes and pathways regulated by these SFs showed substantial overlap, suggesting their coordinated roles in promoting cancer stemness and metastasis. Specifically, alternative splicing of key markers, such as CD44 and , was regulated by most of these SFs and correlated with poor prognosis. Our study unveils six survival-related SFs that contribute to the aggressiveness of esophageal cancer and and alternative splicing may act as common downstream effectors of survival-related SFs. This study provides mechanistic insights into SF-mediated tumorigenesis and highlight novel therapeutic vulnerabilities in esophageal cancer.

摘要

RNA可变剪接是真核基因表达的一种关键调控机制,其中剪接因子(SFs)起着关键调节作用。异常的SF表达驱动致癌剪接变体的产生,从而促进肿瘤发生和恶性进展。然而,SFs的生物学功能和潜在靶点在很大程度上仍未得到充分探索。通过多组学分析,我们在食管癌中鉴定出与生存相关的剪接因子(SFs),并阐明了它们的生物调控网络。为了进一步研究它们的下游剪接靶点,我们将SF基因敲低导致的可变剪接事件与食管癌特异性的可变剪接事件相结合。最后,这些剪接事件通过全长RNA测序得到验证,并在癌细胞和临床标本中得到证实。我们鉴定出六个在食管癌中高表达且与预后不良相关的SFs。进一步分析表明,这些因子与免疫浸润、癌症干性、肿瘤异质性和耐药性显著相关。被鉴定为核心SFs。这些SFs调控的靶基因和通路显示出大量重叠,表明它们在促进癌症干性和转移中发挥协同作用。具体而言,关键标志物如CD44等的可变剪接受这些SFs中的大多数调控,并与预后不良相关。我们的研究揭示了六个与生存相关的SFs,它们促进了食管癌的侵袭性,并且和可变剪接可能作为与生存相关的SFs的共同下游效应器。本研究为SF介导的肿瘤发生提供了机制性见解,并突出了食管癌新的治疗弱点。
