Mechanistic studies revealed that regulated the expression of its nearby gene and inhibited the activity of the PI3K/Akt signaling pathway. These results indicate that downregulation of significantly promotes the progression of GC cells by regulating expression and activating the PI3K/Akt signaling pathway. may be a novel diagnostic biomarker and effective therapeutic target for GC. These results indicate that downregulation of HOXD-AS2 significantly promotes the progression of GC cells by regulating HOXD8 expression and activating the PI3K/Akt signaling pathway. HOXD-AS2 may be a novel diagnostic biomarker and effective therapeutic target for GC. Programmed death ligand 1 (PD-L1) immunotherapy remains poorly efficacious in colorectal cancer (CRC). The recepteur d'origine nantais (RON) receptor tyrosine kinase plays an important role in regulating tumor immunity. To identify the patterns of RON and PD-L1 expression and explore their clinical significance in CRC. Gene expression data from the Gene Expression Omnibus database (GEO; = 290) and patients at the First Affiliated Hospital, Zhejiang University School of Medicine (FAHZUSM; = 381) were analyzed to determine the prognostic value of RON and PD-L1 expression within the tumor microenvironment of CRC. HT29 cell line was treated with BMS-777607 to explore the relationship between RON activity and PD-L1 expression. Signaling pathways and protein expression perturbed by RON inhibition were evaluated by cellular immunofluorescence and Western blot. In the GEO patient cohort, cut-off values for RON and PD-L1 expression were determined to be 7.70 and 4.3, respectively. Stratification of patiever, phosphorylation of RON upregulates PD-L1 expression, which provides a novel approach to immunotherapy in CRC. RON, PD-L1, and their crosstalk are significant in predicting the prognostic v
