CRNDE: A Long Non-Coding RNA Involved in CanceR, Neurobiology, and DEvelopment.

Area of Science:

• Molecular Biology
• Genetics
• Cancer Research

Background:

• Colorectal Neoplasia Differentially Expressed (CRNDE) is a long non-coding RNA (lncRNA) gene.
• CRNDE exhibits tissue-specific expression patterns and multiple splice variants.
• Initially identified in colorectal cancer, CRNDE is upregulated in various solid tumors and leukemias.

Purpose of the Study:

• To investigate the role and function of the CRNDE lncRNA.
• To explore the association of CRNDE with cancer stemness.
• To understand CRNDE's involvement in gene regulation through interactions with protein complexes.

Main Methods:

• Gene expression analysis in various cancer types.
• Bioinformatic analysis to identify splice variants and tissue-specific expression.
• Investigating interactions with Polycomb Repressive Complex 2 (PRC2) and CoREST complexes.

Main Results:

• CRNDE is the most upregulated lncRNA in gliomas and associated with a stemness signature.
• CRNDE is expressed in specific brain regions and in pluripotent stem cells during neuronal differentiation.
• CRNDE splice forms act as scaffolds for regulatory complexes like PRC2 and CoREST.

Conclusions:

• CRNDE is a multifunctional lncRNA implicated in the progression of multiple cancers.
• CRNDE's interaction with chromatin-modifying complexes suggests a role in epigenetic regulation.
• CRNDE's involvement in stemness highlights its potential as a therapeutic target.
