Next, Lasso-cox regression was cross-employed for elaboration of predictive model and MNM-associated hub gene identification in TCGA-STAD and GSE84437 bulk profiles for STAD patients. Besides, deep learning algorithm(SOM) was utilized for risk stratification for STAD patients in TCGA-STAD dataset. Indeed, we also elucidated the molecular and immune heterogeneity of hub gene at bulk(TCGA-STAD cohort) and single-cell transcriptomic(GSE158937) levels of STAD patients, especially in virtual malignant cells at spatial and temporal manners. Besides, GSCA database with ridge regression were cross-performed for identification of optimal therapeutic framework for STAD patient treatment and then validated by molecular docking. Finally, in vitro study examined the relationship between hub gene and STAD cancer cell proliferation, growth and metastasis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>MNM can guide the STAD patient prognostic forecasting and risk stratification.
