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.

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.

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.

Next Generation Sequencing Facilitates Quantitative Analysis of Wild Type and hnRNPA2B1-KO sw480 cell line Transcriptomes

Project description:HNRNPA2B1, an RNA-binding protein, plays a key role in primary microRNA processing, alternative splicing, mRNA metabolism and transport. Interestingly, hnRNPA2B1 also works as an N6-methyladenosine(m6A) reader and is critical during tumorigenesis of various tissue types. However, its role in colon cancer is still unclear. In this study, we aimed to elucidate the biological functions of hnRNPA2B1 and to explore its underlying mechanisms in colon cancer. Methods We examined the expression of hnRNPA2B1 in Oncomine and TCGA databases. Then verified the findings in colon cancer cells and clinical samples with western blotting and immunohistochemistry (IHC). We used CRISPR/Cas9 directed gene editing to knockout hnRNPA2B1 expression in human colon cancer cell line SW480 and carried out both in vivo and in vitro experiments. The results were further confirmed by RNA-seq analysis. We found that hnRNPA2B1 significantly promoted colon cancer cell proliferation both in vitro and in vivo, while knockout of hnRNPA2B1 induced apoptosis and cell cycle arrest in SW480. RNA-seq analysis revealed that the ERK/MAPK pathway was activated by hnRNPA2B1 upregulation. In addition, both hnRNPA2B1 and MAPK pathway were activated in clinical colon cancer specimens and positively correlated. Mechanistically, hnRNPA2B1 appeared to be an upstream regulator of the ERK/MAPK pathway and inhibition of MAPK signaling blocked the effects of hnRNPA2B1. Taken together, our data demonstrated that the RNA-binding protein hnRNPA2B1 promotes cell proliferation and regulates cell cycle and apoptosis of human colon cancer by activating the ERK/MAPK signaling, which may provide a new insight into the development of hnRNPA2B1 as a potential therapeutic target for treatment of colon cancer.
