The invention discloses an application of an IP6K1 gene, an IP6K1 protein and a PAS-A protein fragment in screening and preparing a medicine for preventing and/or treating myocardial infarction diseases or a medicine for improving myocardial cell injury caused by hypoxia. Through research, it is found for the first time that IP6K1 protein is directly combined with a PAS-A substructure domain of HIF-1alpha, and then degradation of the HIF-1alpha, formation of HIF-1alpha/ARNT dimer and combination of the HIF-1alpha and p53 are affected, so that repair of myocardial cell damage caused by hypoxia by the HIF-1alpha is limited, and cell death is aggravated; therefore, the influence caused by myocardial infarction is aggravated. When the IP6K1 gene is knocked out, or the expression of the IP6K1 gene is inhibited, or the IP6K1 protein is degraded, or the expression of a subdomain PAS-A protein fragment of the HIF-1alpha is increased, the combination of the IP6K1 protein and the HIF-1alpha can be eliminated, so that the positive effect of the HIF-1alpha is improved, the repair of myocardial cell injury is improved, the cell survival is promoted, and the adverse influence caused by myocardial infarction is reduced.
