SpyCLIP sequencing of BUD31 in ovarian cancer cells


ABSTRACT: Mis-regulation of splicing factors are thought to activate cancer specific splicing programs that contribute to cancer development and progression. However, it remains a major challenge to identify the key splicing variants caused by aberrant expression of splicing factors in cancer. Here we report that splicing factor BUD31 is commonly overexpressed in high-grade serous ovarian carcinoma (HGSOC) and high level of BUD31 is associated with poor prognosis. RNA-seq analysis reveals that BUD31 inhibition predominantly results in alternation of exon skipping and intron retention. We further identify binding motif and preferred genome-wide binding pattern of BUD31 by CLIP-seq analysis. Our data indicate that BUD31 is a critical oncogenic splicing factor in ovarian cancer and might act as a potential therapeutic target.
