IGF2BP3 mediates m6A-modified E2F2 stability to affect neuroblastoma progression [m6A-seq]

Project description:We report a previously unrecognized role of IGF2BP3 in survival of neuroblastoma cells. To explore IGF2BP3-dependent gene regulation and m6A modification, RNA-seq and m6A-seq analysis was conducted and the differently expressed/modified genes were revealed in the IGF2BP3-knockdown SK-N-BE(2) cells in comparison to control group.

Potential Roles of IGF2BP3 in Bladder Cancer [m6A-seq]

Project description:TCGA data analysis and clinical sample test results showed the IGF2BP3 is highly expressed in bladder cancer and related to tumor metastasis and invasion. RNA sequencing results of clinical bladder tissue from 53 cases showed that the IGF2BP3 expression is related to cell proliferation genes. M6a and RNA sequencing results showed the IGF2BP3 affects the growth, proliferation, and apoptosis of T24 cells, and SpHK1, POMT2, and MRPS18a may be potential targets of IGF2BP3.

IGF2BP3-mediated m6A modification of RASGRF1 promoting joint injury in rheumatoid arthritis [RIP-seq]

Project description:With the deepening of epigenetic research, more and more studies have shown that N6- methyladenosine (m6A) is closely related to the occurrence and development of rheumatoid arthritis (RA), but the specific mechanism still needs to be further elucidated. In the study, we collected synovial tissues from normal controls and patients with OA or RA. The levels of m6A and inflammation were analyzed by immunofluorescence and western blot. The role of IGF2BP3 in cell proliferation and inflammatory activation was explored using transfection and RNA immunoprecipitation assays. IGF2BP3-/- mice were established, which were used to construct a mouse model of arthritis by transferring serum from adult arthritis K/BxN mice. Histological analysis and micro-CT were performed to determine joint damage. m6A level was markedly increased in RA patients and mouse models, and the expression of IGF2BP3 was upregulated in RA and related to inflammatory markers. IGF2BP3 played an important part in RA-fibroblast-like synoviocytes (FLS) by promoting cell proliferation, migration, invasion, inflammatory cytokine release, and inhibiting autophagy. In addition, IGF2BP3 inhibited autophagy to reduce the production of ROS, thereby decreasing inflammatory activation in macrophages. More importantly, RASGRF1-mediated mTORC1 activation played a crucial role in the ability of IGF2BP3 to promote cell proliferation and inflammatory activation. Based on the arthritis model of IGF2BP3-/- mice, IGF2BP3 knockdown Inhibited RA-FLS proliferation and inflammatory infiltration, and further improved RA joint injury. Our study revealed the important role of IGF2BP3 in RA progression. The targeted inhibition of IGF2BP3 reduced cell proliferation and inflammatory activation and limited RA development in a mouse model of arthritis, providing a potential strategy for RA therapy.

4-Vinylcyclohexene diepoxide induces ovarian toxicity and oocyte damage in mice: mechanisms involving m6A/IGF2BP3-mediated meiotic mRNA stability regulation

Project description:This study investigates the role of m6A RNA methylation and IGF2BP3 in VCD-induced ovarian toxicity in mice. VCD exposure caused follicular depletion, oxidative stress, DNA damage, and meiotic defects in oocytes. Mechanistically, VCD altered m6A modifiers (METTL3, FTO, ALKBH5) and destabilized key meiotic mRNAs (e.g., Cenpa, Bub1, Polq) via IGF2BP3 downregulation, leading to spindle defects and chromosomal missegregation. Our findings reveal an m6A/IGF2BP3 axis as a critical mediator of environmental ovotoxicity.

IGF2BP3 promotes mRNA degradation through internal m7G modification [PARCLIP]

Project description:Recent studies have suggested that mRNA internal m7G and its writer protein METTL1 are closely related to cell metabolism and cancer regulation. Here, we identify that IGF2BP family proteins IGF2BP1-3 can preferentially bind internal mRNA m7G. Such interactions, especially IGF2BP3 with m7G, could promote the degradation of m7G target transcripts in cancer cells. IGF2BP3 is more responsive to changes of the m7G modification, while IGF2BP1 prefers m6A to stabilize the bound transcripts. We also demonstrate that p53 transcript, TP53, is m7G-modified at its 3’UTR in cancer cells. In glioblastoma, the methylation level and the half lifetime of the modified transcript could be modulated by tuning IGF2BP3, or by site-specific targeting of m7G through a dCas13b-guided system, resulting in modulation of cancer progression and chemosensitivity.
