Through RNA-seq analysis, we found that brequinar could affect a broad range of genes at the transcriptional level, including genes involved in the DNA damage repair signaling pathway (PIM1, PIM2, MDC1, CHEK1, and CHEK2) and those mutated in DLBCL patients (SNHG5, FBXW8, CDKN2A, etc.)[41–43]. The gene discussed is PIM1; the disease is diffuse large B-cell lymphoma.
