CRISPR-Cas9 knockout screening identifies KIAA1429 as an essential gene in Ewing sarcoma.

ABSTRACT:

Background

Ewing sarcoma (ES) is an aggressive childhood bone and soft tissue cancer. KIAA1429 is one type of N6-methyladenosine (m6A) writer that plays a tumor-progressive role in various cancers, but the role of KIAA1429 in ES remains to be elucidated. The aim of the study was to investigate the role of KIAA1429 in ES.

Methods

We performed a multi-omic screen including CRISPR-Cas9 functional genomic and transcriptomic approaches, and identified that KIAA1429 played a significant role in ES progression. Gene knockdown, quantitative real-time PCR (Q-RT-PCR), immunoblotting, CellTiter-Glo assays, clonogenic assays, a subcutaneous xenograft model and immunohistochemistry were used to assess the functional role of KIAA1429 in ES. We mainly conducted RNA sequencing (RNA-seq) in
