Abstract:
In recent years, novel classes of noncoding RNAs (ncRNAs) have been discovered, which are implicated in diverse functional and regulatory activities. Growing evidence indicates that deregulated ncRNAs play crucial roles in the onset and progression of cancer, including small-cell lung cancer. In this review, we highlight nearly all of the findings regarding the roles and the possible mechanisms of ncRNAs as oncogenes or tumor suppressors in small-cell lung cancer. Furthermore, we discuss the possible role of ncRNAs as diagnostic biomarkers, their significant contribution to the prognosis, and their functions in regulating the response to therapy.
Insights
Noncoding RNAs (ncRNAs) are key players in small-cell lung cancer development. This review explores their roles as oncogenes or tumor suppressors, and as biomarkers for diagnosis and prognosis.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- Noncoding RNAs (ncRNAs) are increasingly recognized for their regulatory roles in cellular processes.
- Dysregulation of ncRNAs is implicated in the pathogenesis of various cancers.
- Small-cell lung cancer (SCLC) is a highly aggressive malignancy with complex molecular underpinnings.
Purpose of the Study:
- To review the current understanding of ncRNAs in small-cell lung cancer (SCLC).
- To elucidate the mechanisms by which ncRNAs function as oncogenes or tumor suppressors in SCLC.
- To discuss the potential of ncRNAs as diagnostic biomarkers and prognostic indicators in SCLC.
Main Methods:
- Comprehensive literature search of studies investigating ncRNAs in small-cell lung cancer.
- Analysis of reported functional roles of ncRNAs, including oncogenic and tumor-suppressive activities.
- Evaluation of evidence for ncRNAs in SCLC diagnosis, prognosis, and therapy response.
Main Results:
- ncRNAs exhibit diverse roles in SCLC, acting as either oncogenes or tumor suppressors.
- Specific ncRNAs are associated with tumor initiation, progression, and metastasis in SCLC.
- ncRNAs show promise as biomarkers for early detection and patient stratification in SCLC.
Conclusions:
- ncRNAs are critical regulators in small-cell lung cancer.
- Targeting ncRNAs may offer novel therapeutic strategies for SCLC.
- ncRNAs hold significant potential for improving diagnosis and prognosis in SCLC patients.
