Area of Science:

  • Oncology
  • Genomics
  • Bioinformatics

Background:

  • Metastatic cutaneous melanoma (SKCM) presents a significant clinical challenge due to high mortality rates.
  • Understanding the molecular differences between primary and metastatic tumors is crucial for effective treatment.

Purpose of the Study:

  • To compare metastatic and primary SKCM cells using single-cell RNA sequencing (scRNA-Seq).
  • To identify key genes and pathways involved in SKCM metastasis.
  • To develop an accurate predictive model for tumor metastasis.

Main Methods:

  • Single-cell RNA sequencing (scRNA-Seq) for cell type annotation and communication analysis.
  • Differential gene expression analysis to identify metastasis-associated genes.
  • Development and validation of a Particle Swarm Optimization-Support Vector Machine (PSO-SVM) classification algorithm.

Main Results:

  • Significant disparities in cell communication and functional pathways between primary and metastatic SKCM cells were identified.
  • A core gene set associated with tumor metastasis was screened, including SFN, S100A8, KLF5, ARL4D, and TINCR.
  • The PSO-SVM model demonstrated superior classification performance compared to traditional machine learning methods in predicting metastasis.

Conclusions:

  • The study elucidated core molecular mechanisms and regulatory pathways in the tumor microenvironment driving SKCM metastasis.
  • Identified genes (SFN, S100A8, KLF5, ARL4D, TINCR) serve as potential biomarkers and therapeutic targets for early diagnosis and treatment.
  • The integrated analytical approach offers novel insights into cancer metastasis research.
