Abstract:
Lung adenocarcinoma is a major public health problem with the low 5-year survival rate (15%) among cancers. Aberrant alterations of meiotic genes, which have gained increased attention recently, might contribute to elevated tumor risks. However, systematic and comprehensive studies based on the relationship between meiotic genes and LUAD recurrence and treatment response are still lacking. In this manuscript, we first confirmed that the meiosis related prognostic model (MRPM) was strongly related to LUAD progression via LASSO-Cox regression analyses. Furthermore, we identified the role of PPP2R1A in LUAD, which showed more contributions to LUAD process compared with other meiotic genes in our prognostic model. Additionally, repression of PPP2R1A enhances cellular susceptibility to nelfinavir-induced apoptosis and pyroptosis. Collectively, our findings indicated that meiosis-related genes might be therapeutic targets in LUAD and provided crucial guidelines for LUAD clinical intervention.
Insights
Meiotic genes, including PPP2R1A, are linked to lung adenocarcinoma (LUAD) progression and treatment response. Targeting these meiosis-related genes may offer new therapeutic strategies for LUAD patients.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Lung adenocarcinoma (LUAD) presents a significant public health challenge with a poor 5-year survival rate.
- Aberrant alterations in meiotic genes are increasingly recognized for their potential role in cancer development.
- A lack of comprehensive studies exists on the connection between meiotic genes and LUAD recurrence and treatment outcomes.
Purpose of the Study:
- To investigate the prognostic value of meiotic genes in LUAD.
- To identify specific meiotic genes that influence LUAD progression and treatment response.
- To explore the therapeutic potential of targeting meiotic genes, specifically PPP2R1A, in LUAD.
Main Methods:
- Utilized LASSO-Cox regression analysis to develop a meiosis-related prognostic model (MRPM) for LUAD.
- Identified and analyzed the role of the gene PPP2R1A within the context of LUAD.
- Investigated the effect of PPP2R1A repression on cellular apoptosis and pyroptosis in response to nelfinavir.
Main Results:
- The developed MRPM demonstrated a strong correlation with LUAD progression.
- PPP2R1A was identified as a key meiotic gene significantly contributing to LUAD processes.
- Repressing PPP2R1A increased LUAD cell susceptibility to nelfinavir-induced apoptosis and pyroptosis.
Conclusions:
- Meiosis-related genes, including PPP2R1A, are implicated in LUAD progression and may serve as prognostic markers.
- Targeting meiosis-related genes presents a potential therapeutic avenue for LUAD.
- These findings offer valuable insights for guiding clinical interventions in LUAD treatment.
