The results showed that in gastric cancer, RORA expression was positively correlated with the expression of NRP1, CD40, CD276, CD86, HHLA2, CD160, TNFSF4, TNFSF18, TNFRSF8, CD244, TNFSF9, CD70, TNFSF14, VTCN1, HAVCR2, CD27, TNFRSF14, ICOS, LGALS9, CD28, TIGIT, TNFRSF4, IDO2, and PDCD1LG2, while it was negatively correlated with LAG3 expression. The gene discussed is TNFSF4; the disease is gastric cancer.
