Stratifying patients by median expression levels, survival analysis revealed that high OLMALINC/TRHDE-AS1/ZNF436-AS1 or low AC027045.3 expression correlated with poorer prognosis (Fig. 6o‒r), in line with previous reports linking elevated TRHDE-AS1 expression to poor gastric cancer outcomes.86 This evidence concerns the gene ZNF436 and gastric cancer.
