Abstract

Long non‑coding RNAs (lncRNAs) play a key role in regulating gene expression, influencing various cellular pathways by interacting with transcription factors, other RNA molecules such as microRNAs (miRNAs) and DNA. The present focused on the role of lncRNAs related to nuclear receptors (NRs), which are a family of transcription factors activated by ligands. NRs are involved in vital biological processes, such as metabolism, immune response, reproduction and development. Herein, six novel sequence motifs were discovered within lncRNAs that respond to multiple NRs, suggesting they are not specific to a single receptor. Of note, one of these motifs, was complementary to miRNA hsa‑miR‑1908‑3p, suggesting that lncRNAs containing this motif may function as miRNA sponges, regulating the expression of ~487 target mRNAs. The motifs were also found in key regulatory regions of the human genome, particularly on chromosome 19, including in adeno‑associated virus integration site 1, a region with a high regulatory role in gene expression. Additionally, an evolutionary analysis was conducted, revealing that these motifs are highly conserved across species, including Mus musculus, Euglena gracilis and Saccharomyces cerevisiae, indicating their ancient origins. Based on these results, it is suggested that these motifs may represent ancestral binding sites for NR precursors, and may function as backup mechanisms in modern organisms, ensuring the functional versatility and evolutionary conservation of NR‑mediated gene regulation.
