HSPB1 and cardiomyopathy: 1. High expression levels during cardiac hypertrophy2. Cardioprotection (Hsp27 has a cardioprotective effect in cases of infarction)3. Overexpression of Hsp27 results in reduction in cell apoptosis in cardiac tissue4. High Hsp25 expression improved survival of cardiomyopathy patients and the heart resistance against toxicity
