Forensic Context
A study in humans identified the GTF2H4 as a potential transcriptional regulator significantly associated with myocardial ischaemia reperfusion injury (IRI) following percutaneous coronary intervention, showing a positive correlation with IRI and enrichment in the cellular response to stress within a constructed lncRNA-mRNA ceRNA network [Liu et al. DOI:10.1111/jcmm.14163].
