IGF2BP1 promotes SRF-dependent transcription in cancer in a m6A- and miRNA-dependent manner [IGF2BP1 and SRF KD in ES-2 (total RNA)]

ABSTRACT: The oncofetal mRNA-binding protein IGF2BP1 and the transcriptional regulator SRF modulate gene expression in cancer. In cancer cells, we demonstrate that IGF2BP1 promotes the expression of SRF in a conserved and N6-methyladenosine (m6A) dependent manner by impairing the miRNA-directed decay of the SRF mRNA. This results in enhanced SRF-dependent transcriptional activity and promotes tumor cell growth and invasion. At the post-transcriptional level, IGF2BP1 sustains the expression of various SRF-target genes. The majority of these SRF/IGF2BP1-enhanced genes, including PDLIM7 and FOXK1, shows conserved upregulation with SRF and IGF2BP1 synthesis in cancer. PDLIM7 and FOXK1 promote tumor cell growth and were reported to enhance cell invasion. Consistently, 35 SRF/IGF2BP1-dependent genes showing conserved association with SRF and IGF2BP1 expression indicate a poor overall survival probability in ovarian, liver and lung cancer. In conclusion, these findings identify the SRF/IGF2BP1-, miRNome- and m6A-dependent control of gene expression as a conserved oncogenic driver network in cancer.

IGF2BP1 is a druggable, post-transcriptional super-enhancer of E2F-driven gene expression hallmark in cancer [IGF2BP1 KD in MV3 (total RNA)]

Project description:The IGF2 mRNA-binding protein 1 (IGF2BP1) is a post-transcriptional enhancer of tumor growth. However, conserved effector pathway(s) and the feasibility of targeting IGF2BP1 in cancer cells remained elusive. We demonstrate that IGF2BP1 is a conserved regulator of E2F-driven gene expression and cancer cell cycle progression. IGF2BP1 promotes positive regulators of G1/S transition by stabilizing the respective mRNAs. This regulation is 3’UTR-, miRNA- and m6A-dependent, suggesting a conserved role of m6A-enhanced cell cycle progression across cancers. IGF2BP1 stabilizes E2F-encoding mRNAs and some of their target transcripts revealing a post-transcriptional super-enhancer role of the protein in E2F-driven gene expression. The small molecule BTYNB disrupts this super-enhancer function by impairing IGF2BP1-RNA association and consequently interferes with tumor cell proliferation and tumor growth.

m6A modification profile in primary microglia with/without Igf2bp1 knockdown

Project description:Our study demonstrated that the expression of Igf2bp1 in activated microglia was significantly up-regulated, implying a role of Igf2bp1 in LPS-induced m6A modifications in microglia. To understand the roles of Igf2bp1 on LPS-induced m6A modification in microglia, we performed Igf2bp1 loss-of-function (LOF) approach. Microglia stimulated by LPS were transfected with either scrambled siRNA control or Igf2bp1 siRNA for 48 hours. To m6A modification profiles in control and Igf2bp1 LOF microglia were determined by MeRIP-seq analysis.
