The HNRNPR Knockout HeLa Polyclonal Cells product provides a CRISPR/Cas9-mediated knockout population of HeLa cells, delivering a versatile loss-of-function model for studying HNRNPR. This polyclonal pool, rather than a clonal isolate, maintains genetic heterogeneity and is generated through targeted disruption of the HNRNPR gene, impairing protein expression. The model is optimized for reproducible research outcomes in RNA biology, cancer research, and neurodegenerative disease studies.
The HeLa cell line is a human cervical adenocarcinoma line with epithelial morphology and is HPV18-positive. Isolated from a cervical tumor, HeLa cells are a classic model in cancer biology, virology, and cellular biochemistry. Their rapid growth, transfectability, and extensive characterization make them ideal for generating knockout models to probe gene function in a cancerous epithelial context. The HPV18 background provides additional relevance for exploring interactions between viral oncoproteins and host RNA processing machinery.
HNRNPR encodes an RNA-binding protein that regulates mRNA processing, transport, and stability. It assembles into ribonucleoprotein complexes with the SMN protein, Gemin proteins, and other hnRNPs. Key target transcripts include SMN mRNA and ??-actin mRNA. HNRNPR acts downstream of general transcription factors and cellular stress cues. Its disruption compromises SMN complex formation and alters the expression and localization of target mRNAs, perturbing RNA metabolic networks.
In HeLa cells, HNRNPR knockout illuminates how RNA-binding protein dysfunction intersects with cancer biology. Loss of HNRNPR may dysregulate post-transcriptional control of mRNAs involved in proliferation, stress, and apoptosis, which are relevant to cervical adenocarcinoma pathology. Additionally, HNRNPR’s links to amyotrophic lateral sclerosis and spinal muscular atrophy position this model at the interface of cancer and neurodegeneration research, enabling comparative studies of RNA processing pathways shared between these diseases.
Applications include RT-qPCR and RNA immunoprecipitation to assess mRNA processing, western blotting for protein analysis, immunofluorescence for localization, and functional assays for proliferation and apoptosis. This polyclonal knockout model is ideal for comparing RNA metabolism alterations versus wild-type HeLa cells, aiding in the dissection of HNRNPR-dependent mechanisms in stress granule dynamics and splicing.
