It was experimentally proven that greater heart muscle load influences gene expressions
that are related to increased cellular demand for zinc, which is involved in transcription,
translation, and enzymatic and structural protein syntheses [9–11]. Increased accumulation
of calcium and zinc was reported in hypertrophic cardiomyopathy in hamsters [12]. Higher
zinc content is thought to be connected to intensified intracellular damage repair
mechanisms that are the result of genetically determined changes in structure of proteins
of cardiomyocytes [12]. The mutations could concern sites where zinc is being incorporated
and disrupt the zinc-fingers forming process, which would cause lower stability of proteins
and increased tendency to proteolysis
