Long intergenic non-protein coding RNA 477 (LINC00477)

Long intergenic non-protein coding RNA 477 (LINC00477) is a human lncRNA gene on chromosome 12, predominantly classified as an intergenic non-coding RNA with no canonical protein product[3]. LINC00477 is expressed in various tissues and is upregulated in several human cancers, where it participates in cell proliferation, chemoresistance, migration, and the suppression of apoptosis by sponging specific miRNAs or interacting with transcriptional regulators such as NF-κB and EZH2[1]. LINC00477 functions mainly as a competing endogenous RNA (ceRNA), regulating the availability and function of target microRNAs and their downstream effectors. Its elevated expression is associated with poor prognosis and tumor aggressiveness, making it a potential biomarker and target for experimental therapeutics in oncology[1]. Some commercial products and sequence analyses refer to a putative protein encoded by LINC00477, but current genetic and transcriptomic evidence classifies the locus as non-coding[2][3].
