A method for the early diagnosis, prognosis and differentiation of ischemic cardiac events in myocardial ischemia by a Nourin gene-based RNA molecular network of biomarkers related to the Nourin peptide sequence, comprising:
- obtaining a sample from a subject;
- and
- assaying the sample for one or more of a Nourin gene-based RNA molecular network of biomarkers related to the Nourin peptide sequence, comprising:
- i) anaphase promoting complex subunit mRNA-11 (mRNA-ANAPC11) gene;
- ii) ferritin heavy chain like polypeptide mRNA-17 (mRNA-FTHL-17) gene;
- iii) Homo sapiens micro RNA-106b (hsa-miRNA-106b);
- iv) Homo sapiens micro RNA-137 (hsa-miRNA-137);
- v) Nourin gene mRNA (mRNA-Nourin);
- and
- vi) long non-coding intergenic RNA (lnc-RNA-CTB89H12.4),
- wherein, hsa-miRNA-137 is a marker of cell damage,
- wherein, hsa-miRNA-106b is a marker of cardiovascular inflammation,
- wherein, hsa-miRNA-137 and hsa-miRNA-106b regulate the expression of Nourin gene and are linked to myocardial ischemia and ischemic cardiac events,
- wherein, hsa-miRNA-137 and hsa-miRNA-106b are upregulated after ischemic cardiac events in myocardial ischemia and are linked to overexpression of mRNA-FTHL-17 and mRNA-ANAPC11,
- wherein, hsa-miRNA-137 and hsa-miRNA-106b are upstream regulated by lnc-RNA-CTB89H12.4,
- wherein, lnc-RNA-CTB89H12.4 is downregulated after ischemic cardiac events in myocardial ischemia and is linked to higher levels of hsa-miRNA-137 and hsa-miRNA-106b, and to overexpression of mRNA-FTHL-17 and mRNA-ANAPC11,
- wherein, lnc-RNA-CTB89H12.4 is downregulated after ischemic cardiac events in myocardial ischemia and is linked to increased translation and production of high levels of Nourin protein,
- wherein, hsa-miRNA-137, hsa-miRNA-106b, mRNA-FTHL-17, mRNA-ANAPC11, Nourin gene, and Nourin protein show extremely low or no expression in the samples from healthy, non-ischemic, non-cardiac subject, and
- wherein, lnc-RNA-CTB89H12.4 is upregulated in the samples from healthy, non-ischemic, non-cardiac subject.
