HnRNPA2B1 promotes osteogenesis differentiation of human adipose-derived stem cells through PHC2/GATA6/BMP axis [CUT&RUN]

ABSTRACT: m6A modification is prevalent on messenger RNA and plays a crucial role in various eukaryotic biological processes, including growth, development, disease, and aging. hnRNPA2B1, a member of the heterogeneous nuclear ribonucleoprotein (hnRNP) family, has been identified as an m6A reader. In this study, hnRNPA2B1 was shown to promote osteogenesis differentiation of human adipose-derived stem cells (hASCs) in vitro. Furthermore, the overexpression of hnRNPA2B1 facilitated bone defect healing in in vivo models of bone defects. hnRNPA2B1 RIP-seq, mRNA-seq, and MERIP-seq were used to identify PHC2 as the target gene of hnRNPA2B1. hnRNPA2B1 enhances the stability of PHC2 mRNA through m6A regulation. PHC2 binds to the promoter region of GATA6 and represses GATA6 expression by increasing H3K27me3 levels. GATA6, in turn, inhibits BMP signaling pathways and the osteogenesis differentiation of hASCs. hnRNPA2B1-PHC2-GATA6-BMP axis offers a promising perspective for the development of stem cell based bone tissue engineering.

Nuclear HNRNPA2B1 HITS-CLIP and RNA-seq

Project description:To identify HNRNPA2B1 binding sites on endogenous nuclear RNAs, we performed HITS-CLIP for endogenous HNRNPA2B1 and RNA-seq to analyze the nuclear RNA under either METTL3 or HNRNPA2B1 depletion. Wild type MDA-MB-231 cells were subjected to the HITS-CLIP procedure on immunoprecipitated HNRNPA2B1 associated RNA obtained from the nuclear fraction (Licatalosi D, et al. 2008, Nature 456:464-U22). For RNA-seq, nuclear RNA was extracted from MDA-MB-231 or Hela cells knocked down for METTL3 or HNRNPA2B1.

MeRIP-Seq map HNRNPA2B1 maintains MM tumorigenicity by m6A dependent stabilizing of mRNA

Project description:To investigated the mechanism of HNRNPA2B1 in MM tumorigenesis, performed m6A IP seq analysis (MeRIP-Seq) to identify the expression changes in stable HNRNPA2B1-knockdown MM cells.60 genes m6A with over 2-fold expression change in shHNRNPA2B compared with control in both ARP1 and H929 cells.44 differentially expressed genes (P<0.05) in both m6A and transcription in shHNRNPA2B compared with control in ARP1 cell.

DRAIC mediates hnRNPA2B1 stability and m6A-modified IGF1R instability to inhibit tumor progression

Project description:Both N6-methyladenosine (m6A) mediates RNA fates and ubiquitin mediates protein fates play an important role in either physiology or pathology including cancer, yet how long noncoding RNAs (lncRNAs) are involved in a link of molecular fate between m6A and ubiquitin remains unknown. Here, we reveal a role for a lncRNA Downregulated RNA in Cancer (DRAIC) to suppress tumor growth and metastasis in clear cell Renal Carcinoma (ccRCC). Mechanistically, DRAIC physically interacts with heterogeneous nuclear ribonucleoprotein A2B1 (hnRNPA2B1) and enhances its protein stability by blocking E3 ligase F-box protein 11 (FBXO11)-mediated ubiquitin and proteasome-dependent degradation. Subsequently, hnRNPA2B1 destabilizes m6A modified-type 1 insulin-like growth factor receptor (IGF1R) to lead to inhibition of ccRCC progression. Moreover, four m6A modification sites of IGF1R are identified and results in its mRNA degradation. Collectively, our findings reveal that DRAIC/hnRNPA2B1 axis regulates IGF1R mRNA expression in an m6A-dependent manner and highlights an important mechanism of IGF1R fate. These findings shed light on DRAIC/hnRNPA2B1/FBXO11/IGF1R axis as potential therapeutic targets in ccRCC and build a link of molecular fate between m6A-modified RNA and ubiquitin-modified protein.

Identification of HNRNPA2B1-regulated miRNA targets in breast cancer cells

Project description:Higher N(6)-methyladenosine (m6A) was identified in selected primary microRNAs (pri-miRNAs) as associated with increased levels of the corresponding mature miRNA in MDA-MB-231 triple negative breast cancer (TNBC) cells (PMID: 25799998). HNRNPA2B1 is a reader of the m6A mark in pri-miRNAs and interacts directly with DGCR8 (a component of the nuclear DROSHA complex) to promote processing of pri-miRNAs to precursor-miRNAs (pre-miRNAs) (PMID: 26321680). We have preliminary data showing that HNRNPA2B1 is increased in TAM-resistant, ERα+ LCC9 cells derived from TAM-sensitive, ERα+ MCF-7 breast cancer cells. We found that high HNRNPA2B1 transcript levels in primary breast tumors are associated with reduced overall survival. We postulate that an increase in HNRNPA2B1 targets its binding to additional pri-miRNAs (not normally bound under wild type conditions), resulting in an increase in miRNAs, including those that promote TAM-resistance.

Ectopic Hedgehog signalling causes cleft palate and defective osteogenesis

Project description:In this study, we have investigated the molecular basis of Shh signalling during development of the secondary palate and how CNCC patterning and fate is influenced by the Shh signalling network. Using a gain-of-function mouse model to activate Smoothened (R26SmoM2) signalling in the palatal mesenchyme (Osr2-IresCre), we demonstrate ectopic Hh-Smo signalling results in fully penetrant cleft palate, disrupted oral-nasal patterning and defective palatine bone formation. We show that a series of Fox transcription factors, including the novel direct target Foxl1, function downstream of Hh signalling in the secondary palate. Furthermore, we demonstrate that Wnt/BMP antagonists, in particular Sostdc1, are positively regulated by Hh signalling, concomitant with down-regulation of key regulators of osteogenesis and BMP signalling effectors. Microarray analysis was performed on excised palatal shelves from Osr2-IresCre+/- (wild-type) and Osr2-IresCre;Smo+/M2 (mutant) embryos at embryonic day (E)13.5. Osr2-IresCre (PMID:17941042) and R26SmoM2 (PMID:15107405) mice have been described previously.
