Colorectal cancer (CRC) was one of the most commonly diagnosed malignancies. The molecular mechanisms involved in the progression of CRC remain unclear. Accumulating evidences showed that long noncoding RNAs (lncRNAs) played key roles in tumorigenesis, cancer progression, and metastasis. Researchers at Fudan University aimed to explore the roles of lncRNAs in the progression of CRC. In this study, the researchers aimed to ...

Liver metastasis is the primary cause of death for colorectal cancer (CRC) patients. To investigate the prognostic value of long non-coding RNAs (lncRNAs) on colorectal liver metastases, quantitative reverse-transcriptase PCR (quantitative RT-PCR) was performed on 15 lncRNAs in 51 stage IV CRC with liver metastases and 57 stage I/II CRC specimens. The expression levels of four lncRNAs (GAS5, H19, MEG3 ...

Long noncoding RNAs (lncRNAs) have emerged as key components in multiple cellular processes, although their physiological and pathological functions are not fully understood. To identify cancer-related lncRNAs, researchers at the Sapporo Medical University screened for those that are epigenetically silenced in colorectal cancer (CRC). Through a genome-wide analysis of histone modifications in CRC cells, they found that the transcription start ...

Long non-coding RNA and mRNAs are long RNAs (> 200 nucleotides) compared to microRNAs. In blood, long RNAs may be protected by serum extracellular vesicles, such as apoptotic bodies (ABs), microvesicles (MVs), and exosomes (EXOs). They are potential biomarkers for identifying cancer. Sera from 76 pre-operative CRC patients, 76 age- and sex-matched healthy subjects and 20 colorectal adenoma (CA) patients ...

Long non-coding RNAs (lncRNAs) are a class of newly identified non-coding RNA molecules that are emerging as key regulators of tumor initiation and development. Colorectal cancer (CRC) remains a major health problem worldwide, and there remains a need to further refine the current screening approaches as well as provide tailored diagnostic and therapeutic approaches. Multiple dysregulated lncRNAs participate in tumorigenesis ...
Read More »Featured long non-coding RNA - CRNDE
Colorectal neoplasia differentially expressed (CRNDE) is a novel gene that is activated early in colorectal cancer but whose regulation and functions are unknown. CRNDE transcripts are recognized as long noncoding RNAs (lncRNAs), which potentially interact with chromatin-modifying complexes to regulate gene expression via epigenetic changes. Complex alternative splicing results in numerous transcripts from this gene, and researchers at CSIRO, Australia ...
