HnRNPC engages mature RNAs during metaphase: RNA-seq and fCLIP in proTAME-arrested HeLa/HeLa S3 cells

ABSTRACT: Proper progression through mitosis requires coordinated changes in RNA metabolism, but the specific contributions of individual RNA-binding proteins remain unclear. Heterogeneous nuclear ribonucleoprotein C (hnRNPC) is a ubiquitous RBP that normally binds uridine-rich sequences to influence pre-mRNA processing and stability. Here we investigated the role of hnRNPC in mitotic cells by profiling both global RNA abundance and hnRNPC–RNA interactions during metaphase arrest. To this end, we combined bulk RNA-seq with fluorescent crosslinking and immunoprecipitation (fCLIP) in proTAME-arrested HeLa S3 cells. This dataset enables the characterization of hnRNPC binding to mature RNAs during mitosis, the evaluation of biochemical fractionation (low-density vs high-density complexes), and the assessment of binding site resolution across distinct RNase digestion conditions. Together, the study provides a resource for exploring how hnRNPC contributes to RNA stability and gene expression control during cell division

Analysis of HNRNPC Interactome in MDA-MB231 parental and LM2 cells

Project description:To define and compare the interactomes of the RNA binding protein HNRNPC in poorly vs. efficiently metastatic breast adenocarcinoma cells, we carried out immunoprecipitation of endogenous HNRNPC from parental MDA-MB231 cells vs. its highly metastatic isogenic derivate, the MDA-MB231-LM2 cells. We used a non-specific MOUSE IgG IP from each line as control. Each IP was performed in triplicate, and analysed by LC-MS/MS, on a Thermo Q-Exactive-plus instrument.

Function of HNRNPC in breast cancer cells by controlling the dsRNA-induced interferon response

Project description:Elevated expression of RNA binding protein HNRNPC has been reported in cancer cells, while the essentialness and functions of HNRNPC in tumors were not clear. We showed that repression of HNRNPC in the breast cancer cells MCF7 and T47D inhibited cell proliferation and tumor growth. Our computational inference of the key pathways and extensive experimental investigations revealed that the cascade of interferon responses mediated by RIG-I was responsible for such tumor-inhibitory effect. Interestingly, repression of HNRNPC resulted in accumulation of endogenous double-stranded RNA (dsRNA), the binding ligand of RIG-I. These up-regulated dsRNA species were highly enriched by Alu sequences and mostly originated from pre-mRNA introns that harbor the known HNRNPC binding sites. Such source of dsRNA is different than the recently well-characterized endogenous retroviruses that encode dsRNA. In summary, essentialness of HNRNPC in the breast cancer cells was attributed to its function in controlling the endogenous dsRNA and the down-stream interferon response. This is a novel extension from the previous understandings about HNRNPC in binding with introns and regulating RNA splicing.

Transcription profiling by high throughput sequencing of HNRNPC knockdown and control HeLa cells

Project description:We performed RNA-seq experiments on two replicate samples from each HNRNPC knockdown (KD1 and KD2) As well as from control HeLa cells. Library preparation was preformed according to mRNA Sequencing Sample Preparation Guide (Illumina, Part # 1004898 REV. D). Reagents were taken from the Illumina sample preparation kit (Illumina, CAT # RS-930-1001). Knockdown and control samples were sequenced together in one flowcell on one and two lanes, respectively.

The m6A reader HNRNPC promotes glioma progression by enhancing the stability of IRAK1 mRNA through the MAPK pathway

Project description:Glioma is the most common and aggressive primary malignant brain tumor. N6-methyladenosine (m6A) modification widely exists in eukaryotic cells and plays an important role in the occurrence and development of human tumors. Here, we show that the m6A reader HNRNPC was overexpression and related to poor prognosis in glioma patients. HNRNPC plays crucial role in glioma cell proliferation, invasion and tumorigenesis. HNRNPC augments m6A-dependent mRNA stability of IRAK1, which impacted poor survival for glioma patients, further activated the downstream MAPK pathway. HNRNPC promotes glioma cells progression largely through the upregulation of IRAK1. Together, our findings demonstrate the novel HNRNPC-IRAK1-MAPK axis critical for glioma tumorigenesis and extend the reason for the upregulation of IRAK1.

Differentially expressed genes in HNRNPC knockdown MHCC97H cells

Project description:HNRNPC plays an important role in HCC metastasis, HNRNPC knockdown by specific shRNA (HNRNPC-shRNA) significantly inhibited the migration and invasion of MHCC97H cells, while HNRNPC overexpression exerted the opposite effect. To elucidate the mechanisms by which HNRNPC facilitated HCC metastasis, we performed microarray analysis to compare the transcription profiling between the MHCC97H-shcontrol and MHCC97H-shHNRNPC cells.

The aberrant inclusion of BOLA3 exon 3 promoted by HNRNPC acts as an oncogenic driver in esophageal squamous cell carcinoma [shHNRNPC RNA-seq]

Project description:Aberrant RNA splicing events produce transcripts to facilitate ESCC progression, yet how this splicing process is abnomally regulated remains elusive. Here, we unveil a alternative splicing axis of BOLA3 transcripts and its regulator HNRNPC in ESCC.The long isoform of BOLA3 (-L) with exon3 is highly expressed in ESCC and associated with poor prognosis. Functional assays demonstrate the pro-tumorigenic function of BOLA3-L in ESCC cells. HNRNPC binds to BOLA3-L pre-mRNA and promotes exon3 inclusion forming BOLA3-L. HNRNPC knockdown suppresses the tumorigenesis of ESCC cells, phenocopying BOLA3-L knockdown, which is significantly rescued by BOLA3-L overexpression. High expression of HNRNPC is correlated with the exon-3 inclusion of BOLA3 in ESCC and associated with poor prognosis. BOLA3-L maintains mitochondrial structural and functional stability, exerting pro-oncogenic effects through the WNT/β-catenin pathway. E2F7 acts as a key transcription factor to regulate the transcriptional upregulation of HNRNPC and promotes the inclusion of BOLA3 exon3.Taken together, our findings provide insights into how alternative splicing contributes to ESCC progression, by investgating a HNRNPC-BOLA3 splicing axis.
