We eventually identified four RBPs strongly associated with the occurrence of PM in GC patients by Lasso Logistics analysis in the training set (Figure 1); chosen genes including Collagen Type XIV Alpha 1 Chain (COL14A1), Tensin 1 (TNS1), Nucleolar and Spindle Associated Protein 1 (NUSAP1) and Tyrosine 3-Monooxygenase/Tryptophan 5-Monooxygenase (YWHAE). This evidence concerns the gene COL14A1 and gastric cancer.
