BRIP1 and gastric cancer: By integrating the Cancer Genome Atlas (TCGA) and Gene Set Enrichment Analysis (GSEA) databases with Least Absolute Shrinkage and Selection Operator (LASSO) regression, a novel risk score to stratify GC patients based on prognosis was generated, and a significantly differentially expressed gene, <i>BRIP1</i>, was validated through reverse transcription quantitative polymerase chain reaction (RT-qPCR).
