The m6A Reader IGF2BP2 Regulates Glutamine Metabolism and Represents a Therapeutic Target in Acute Myeloid Leukemia [RNA-seq]

Project description:We report that m6A reader IGF2BP2 participates in the regulation of glutamine metabolism in AML. Targeting IGF2BP2 with our developed inhibitor CWI1-2 shows promising therapeutic efficacy in AML.To explore the mechanism of the inhibitor, we performed RNA-seq in AML cells upon treatment with CWI1-2 or DMSO. On the other hand, to distinguish the mechanism between IGF2BP2 and YTHDF2, we compare RNA-seq data of IGF2BP2 KD with YTHDF2 KD.

Inhibition of the m6A Reader IGF2BP2 as a Strategy against T-cell Acute Lymphoblastic Leukemia

Project description:N6-methyladenosine (m6A) reader Insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2) participates in the initiation and growth of cancers by communicating with various targets. Here, we found IGF2BP2 is highly expressed in T-ALL. Gain and loss of IGF2BP2 demonstrated IGF2BP2 was essential for T-ALL cell proliferation in vitro and loss of IGF2BP2 prolonged animal survival in a human T-ALL xenograft model. Mechanistically, IGF2BP2 directly bound to T-ALL oncogene NOTCH1 via an m6A dependent manner.

Inhibition of the m6A Reader IGF2BP2 as a Strategy against T-cell Acute Lymphoblastic Leukemia

Project description:T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive malignant leukemia with extreme limited treatment for relapsed patients. N6‐methyladenosine (m6A) reader Insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2) participates in the initiation and growth of cancers by communicating with various targets. Here, we found IGF2BP2 is highly expressed in T-ALL. Gain and loss of IGF2BP2 demonstrated IGF2BP2 was essential for T-ALL cell proliferation in vitro and loss of IGF2BP2 prolonged animal survival in a human T-ALL xenograft model. Mechanistically, IGF2BP2 directly bound to T-ALL oncogene NOTCH1 via an m6A dependent manner. Furthermore, we identified a small-molecule IGF2BP2 inhibitor JX5 and treatment of T-ALL with JX5 showed similar functions as knockdown of IGF2BP2. These findings not only shed light on the role of IGF2BP2 in T-ALL, but also provide an alternative γ‑Secretase inhibitors (GSI) therapy to treat T-ALL.

The m6A reader IGF2BP2 regulates macrophage phenotypic activation and inflammatory diseases by stabilizing TSC1 and PPARγ

Project description:Phenotypic polarization of macrophages is regulated by a milieu of cues in the local tissue microenvironment. Currently, little is known about how the intrinsic regulators modulate pro-inflammatory (M1) versus pro-healing (M2) macrophages activation. Here, we observed that insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2) -deleted macrophages exhibited enhanced M1 phenotype and promoted DSS induced colitis development. However, the IGF2BP2-/- macrophages were refractory to IL4 induced activation and alleviated cockroach extract induced pulmonary allergic inflammation. Molecular studies indicated IGF2BP2 switched M1 macrophages to M2 activation by targeting tuberous sclerosis 1 (TSC1) via an N6-methyladenosine-dependent manner. Additionally, we also showed a signal transducer and activators of transcription 6 (STAT6) - high mobility group AT-hook 2 (HMGA2) -IGF2BP2-peroxisome proliferator activated receptor-γ (PPARγ) axis involves in M2 macrophages differentiation. These findings highlight a key role of IGF2BP2 in regulation of macrophages activation and imply a potential therapeutic target of macrophages in the inflammatory diseases.

Enhanced CLIP-seq analysis of PTBP1 and IGF2BP2 binding targets

Project description:To investigate the binding targets of PTBP1 (PTB) and IGF2BP2 (IMP2) in glioma cells, we carried out an unbiased analysis of transcripts bound by PTBP1 and IGF2BP2 using enhanced crosslinking immunoprecipitation followed by high-throughput sequencing (eCLIP) in A172 glioma cells. We repeated the eCLIP method twice in each experiment, and found that the ratio of PTBP1 and IGF2BP2 binding mRNAs overlap was very high.

The interactome of Insulin-like growth factor 2 mRNA binding protein 2 (IGF2BP2)

Project description:Insulin-like growth factor 2 mRNA binding protein 2 (IGF2BP2) binds various RNA transcripts and functions as a tumor promoter, although little is known regarding the mechanisms that regulate its roles in RNA metabolism (1-3). Here we find that IGF2BP2 binds to the 3’ untranslated region of the transcript encoding ATP6V1A, a major catalytic subunit of the vacuolar ATPase (v-ATPase), and regulates its degradation in a lysine acetylation and SIRT1-dependent manner. We show that the regulation of IGF2BP2 is significantly compromised in breast cancer cells where SIRT1 expression is low or knocked-down. Reduced SIRT1 expression leads to an increase in acetylated IGF2BP2, which enables IGF2BP2 to recruit the XRN2 nuclease to the ATP6V1A transcript, resulting in its degradation and a reduction in the expression of functional v-ATPase complexes. This impairs lysosomal activity and produces a cellular secretome consisting of increased numbers of exosomes enriched in ubiquitinated protein cargo and soluble hydrolases including cathepsins, which combine to promote tumor progression and invasiveness. Collectively, these findings describe a previously unrecognized role for IGF2BP2 in mediating the degradation of an mRNA transcript essential for lysosomal function and highlight how its sirtuin-regulated acetylation state can have significant biological and disease consequences.

IGF2BP2-regulated alternative splicing of NFIC causes excessive granulosa cell proliferation in PCOS [IRIP-seq]

Project description:The expression of IGF2BP2 in GCs from PCOS patients was detected using RT-qPCR and western blot. We captured IGF2BP2-interacting transcripts, global transcriptome together with alternative splicing by RNA immunoprecipitation sequencing (RIP-seq) and RNA sequencing (RNA-seq). KGN cells transfected with IGF2BP2 overexpressing plasmids and nuclear factor 1 C-type (NFIC) siRNAs, were applied to CCK-8, EdU and TUNEL assays. IGF2BP2 was highly expressed in GCs from PCOS patients. As a RBP, it preferentially bound to the 3’and 5’UTRs of mRNAs with GGAC motif and a newly found GAAG motif. The overexpression of IGF2BP2 changed the transcriptome profile of KGN cells. IGF2BP2 functioned to regulate alternative splicing events (ASEs) and promote cell proliferation through inhibiting exon skipping events of NFIC. In conclusion, we demonstrated that IGF2BP2 promotes granulosa cell proliferation via regulating alternative splicing of NFIC in PCOS. The findings help to better understand the roles of IGF2BP2 in the pathogenesis of PCOS.
