Abstract:
Background: Long chain non-coding RNAs (lncRNA) are a kind of transcript
that is around 200 nucleotides long and can engage in life activities via epigenetic, transcriptional,
and post-transcriptional regulation. One of the key members of lncRNAs,
long stress-induced noncoding transcripts 5 (LSINCT5), is localized at Chr 5p and has
been reported to be abnormally expressed in a range of cancers. We present a comprehensive
review of LSINCT5's aberrant expression and regulatory mechanisms in malignant
tumors.
Methods: The included studies were retrieved and summarized through the PubMed
database using the keywords “LSINCT5” and “Cancer” in detail.
Results: LSINCT5 behaves as an oncogene and abundantly expresses in malignant tumorigenesis
and progression. By sponging microRNAs (miRNA), interacting with proteins,
participating in cellular transduction, and being regulated by transcription factors,
LSINCT5 can stimulate malignant behavior in a variety of tumor cells, including proliferation,
migration, invasion, and epithelial-mesenchymal transition (EMT). Furthermore,
dysregulated LSINCT5 is usually associated with a poor prognosis.
Conclusion: LSINCT5 has the potential to become a tumor diagnostic and prognostic
marker, generating new access to clinical applications.
