The main signal pathways involved in differential proteins include: motor proteins, protein digestion and absorption, focal adhesion, human papillomavirus infection, ECM-receptor interaction, PIK-Akt signaling pathway, adrenergic signaling in cardiomyocytes, cardiac muscle contraction, dilated cardiomyopathy, hypertrophic cardiomyopathy, and so on. The gene discussed is AKT1; the disease is dilated cardiomyopathy.
