Long noncoding RNA (lncRNA) LINC-PINT acts as a tumor suppressor in many cancers by inhibiting growth and promoting cell death. Further research is needed to fully understand its therapeutic potential in cancer treatment.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- Long noncoding RNAs (lncRNAs) are crucial regulators of biological processes and implicated in various diseases, including cancer.
- Initially considered transcriptional byproducts, lncRNAs are now known to influence chromatin structure, transcription, RNA processing, translation, and nuclear transport.
- LINC-PINT, a P53-induced lncRNA, demonstrates significant tumor suppressor activity across diverse cancer types.
Purpose of the Study:
- To provide a comprehensive overview of the functions and mechanisms of LINC-PINT in cancer.
- To analyze existing literature on LINC-PINT's role in tumor suppression.
Main Methods:
- A systematic literature review was conducted using the PubMed database.
- Inclusion criteria focused on relevance, study quality, and data availability.
- Analysis encompassed 128 studies detailing LINC-PINT's functions and mechanisms in various cancers.
Main Results:
- LINC-PINT functions as a tumor suppressor in numerous cancers, including breast, lung, gastric, and liver cancers.
- Its mechanisms involve promoting apoptosis and senescence, inhibiting proliferation, migration, invasion, and drug resistance.
- LINC-PINT also impacts cell stemness, epithelial-mesenchymal transition (EMT), radioresistance, and DNA damage repair.
Conclusions:
- LINC-PINT acts as a tumor suppressor through mechanisms like miRNA sponging, epigenetic regulation, and DNA damage repair modulation.
- Its complex and tissue-specific functions require further investigation.
- LINC-PINT holds potential as a therapeutic target for cancer treatment, necessitating continued clinical validation.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
