Deciphering FOXM1 regulation: implications for stemness and metabolic adaptations in glioblastoma

The Forkhead box M1 (FOXM1) gene-mediated Wnt signaling pathway plays a significant role in the development and growth of glioblastoma multiforme (GBM), an exceptionally aggressive form of brain cancer. Our research explores the crucial involvement of the FOXM1 gene, a key transcription factor within the Wnt signaling pathway using bioinformatics techniques in both GBM and glioma stem cells (GSCs). Elevated FOXM1 gene expression is strongly associated with poor patient survival in GBM. Furthermore, FOXM1 gene expression is correlated with stemness-related factors, such as SOX2 and SOX9, which act as key drivers in the progression of cancer stem cells. Moreover, we specifically look into the direct associations of the FOXM1 gene with angiogenetic-related factors, metabolic genes, metastatic genes, pluripotency-related factors, immune cell infiltration, transcriptional networks, and functional category enrichment analysis, shedding light on the intricate molecular mechanisms involved in GBM initiation and progression. Additionally, our research identifies FOXM1-targeting miRNAs, revealing their potential as therapeutic candidates with implications for patient survival rates and DNA methylation patterns of the FOXM1 gene, uncovering insights into its epigenetic regulation. This knowledge contributes to a comprehensive understanding of the molecular landscape and potential avenues for developing more effective therapeutic approaches against GBM and GSCs.
