Abstract:
The migrasome, a recently identified cellular organelle, is closely associated with cell migration and plays a critical role in various physiological and pathological processes. The relationship between migrasomes and the prognosis of kidney cancer patients remains unclear. We utilized least absolute shrinkage and selection operator (LASSO) Cox regression analysis on data from The Cancer Genome Atlas- kidney renal clear cell carcinoma (TCGA-KIRC) dataset to identify migrasome-related long non-coding RNAs (lncRNAs) with prognostic significance in KIRC. We then developed and validated a prognostic risk model based on these lncRNAs. In addition, to identify potential immunotherapeutic agents, we analyzed tumor immune dysfunction and exclusion scores; we also conducted immune cell infiltration profiling. Risk score analysis identified 12 migrasome-related lncRNAs significantly associated with the prognosis of TCGA-KIRC patients. Kaplan-Meier survival analysis demonstrated that the prognostic model effectively stratified patients into high- and low-risk groups; the high-risk group showed a significantly worse prognosis relative to the low-risk group. Importantly, higher risk scores were associated with increased immune cell infiltration. This prognostic model underscores the importance of migrasome-related lncRNAs in KIRC and provides a novel tool for predicting patient prognosis and immune response in KIRC.
Insights
Migrasomes and their related long non-coding RNAs (lncRNAs) are crucial for kidney cancer prognosis. A new risk model using these lncRNAs predicts patient outcomes and immune responses in kidney renal clear cell carcinoma.
Area of Science:
- Cell Biology
- Oncology
- Genomics
Background:
- Migrasomes are novel organelles linked to cell migration.
- Their role in kidney cancer prognosis is not well understood.
- Kidney renal clear cell carcinoma (KIRC) is a significant health concern.
Purpose of the Study:
- To investigate the prognostic significance of migrasome-related long non-coding RNAs (lncRNAs) in KIRC.
- To develop and validate a prognostic risk model for KIRC patients.
- To explore the relationship between migrasome-related lncRNAs, prognosis, and tumor immunity.
Main Methods:
- Least Absolute Shrinkage and Selection Operator (LASSO) Cox regression analysis on TCGA-KIRC data.
- Identification of prognostic migrasome-related lncRNAs.
- Development and validation of a prognostic risk model.
- Analysis of tumor immune dysfunction and exclusion scores.
- Immune cell infiltration profiling.
Main Results:
- Twelve migrasome-related lncRNAs were identified as significantly associated with KIRC prognosis.
- The developed prognostic model effectively stratified patients into high- and low-risk groups.
- Higher risk scores correlated with significantly worse prognosis and increased immune cell infiltration.
Conclusions:
- Migrasome-related lncRNAs are important prognostic indicators in KIRC.
- The developed risk model offers a novel tool for predicting KIRC patient prognosis.
- This model may also aid in predicting patient immune response, potentially guiding immunotherapy strategies.
