Integrative Bioinformatics Reveals Novel Molecular Mechanisms and Therapeutic Targets in Acute Myeloid Leukaemia.

ABSTRACT: Acute myeloid leukaemia (AML) is a genetically heterogeneous malignancy associated with poor prognosis and limited treatment options. To identify molecular programs conserved across AML subtypes and perturbations, we analysed three RNA sequencing datasets that captured venetoclax treatment under metabolic stress and the knockdown of chromatin regulators (PSPC1, JMJD1C, and RUNX1). Differential expression analysis was performed using DESeq2, followed by functional enrichment and network analyses. An independent AML cell line dataset was used to validate results. We identified a conserved 73-gene transcriptional signature that is consistently dysregulated across perturbations, characterised by the overexpression of CDKN1A, PHGDH, and ALDH1L2, and the downregulation of MYC and E2F targets.
