Abstract:
Non-small cell lung cancer (NSCLC) has the highest morbidity and mortality among all carcinomas. However, it is difficult to diagnose in the early stage, and current therapeutic efficacy is not ideal. Although numerous studies have revealed that Ailanthone (Aila), a natural product, can inhibit multiple cancers by reducing cell proliferation and invasion and inducing apoptosis, the mechanism by which Aila represses NSCLC progression in a time-dependent manner remains unclear. In this study, we observed that most long noncoding RNAs (lncRNAs) were either notably up- or downregulated in NSCLC cells after treatment with Aila. Moreover, alterations in lncRNA expression induced by Aila were crucial for the initiation and metastasis of NSCLC. Furthermore, in our research, expression of DUXAP8 was significantly downregulated in NSCLC cells after treatment with Aila and regulated expression levels of EGR1. In conclusion, our findings demonstrate that Aila is a potent natural suppressor of NSCLC by modulating expression of DUXAP8 and EGR1.
Insights
Ailanthone (Aila), a natural compound, effectively suppresses non-small cell lung cancer (NSCLC) progression. It achieves this by altering long noncoding RNA (lncRNA) expression, specifically downregulating DUXAP8 and regulating EGR1.
Area of Science:
- Oncology
- Molecular Biology
- Natural Products Chemistry
Background:
- Non-small cell lung cancer (NSCLC) presents significant global health challenges due to high mortality and limited early diagnostic methods.
- Current therapeutic strategies for NSCLC often yield suboptimal outcomes, necessitating the exploration of novel treatment approaches.
- Ailanthone (Aila), a natural product, has demonstrated anti-cancer properties, including inhibition of proliferation, invasion, and induction of apoptosis in various cancer types, but its specific mechanism in NSCLC remains incompletely understood.
Purpose of the Study:
- To elucidate the time-dependent mechanism by which Ailanthone (Aila) suppresses non-small cell lung cancer (NSCLC) progression.
- To investigate the role of long noncoding RNAs (lncRNAs) in Aila-mediated inhibition of NSCLC.
- To identify specific lncRNAs and their regulatory targets involved in Aila's anti-NSCLC effects.
Main Methods:
- Treatment of NSCLC cells with Ailanthone (Aila) and subsequent analysis of long noncoding RNA (lncRNA) expression profiles.
- Assessment of the functional impact of Aila-induced lncRNA alterations on NSCLC cell proliferation, invasion, and apoptosis.
- Investigation of the regulatory relationship between Aila, lncRNAs (specifically DUXAP8), and downstream targets (specifically EGR1) in NSCLC.
Main Results:
- Ailanthone (Aila) treatment led to significant differential expression of numerous long noncoding RNAs (lncRNAs) in NSCLC cells.
- Alterations in lncRNA expression induced by Aila were found to be critical for controlling NSCLC initiation and metastasis.
- Aila significantly downregulated the expression of DUXAP8 and modulated the expression levels of EGR1 in NSCLC cells.
Conclusions:
- Ailanthone (Aila) acts as a potent natural suppressor of non-small cell lung cancer (NSCLC).
- The anti-cancer effects of Aila in NSCLC are mediated through the modulation of specific long noncoding RNAs (lncRNAs).
- DUXAP8 and EGR1 are key molecular targets in the Aila-driven suppression of NSCLC progression.
