Abstract: Fish skeletal muscle is a component of the human diet, and understanding the mechanisms that control muscle growth can contribute to improving production in this sector and benefits the human health. In this sense, fish such as tambacu can represent a valuable source for exploring muscle growth regulators due to the indeterminate muscle growth pattern. In this context, the genes responsible for the indeterminate and determinate muscle growth pattern of fish are little explored, with piwi genes being possible candidates involved with these growth patterns. Piwi genes are associated with the proliferation and self-renewal of germ cells, and there are descriptions of these same functions in somatic cells from different tissues. However, little is known about the function of these genes in fish somatic cells. Considering this, our objective was to analyze the expression pattern of piwi 1 and 2 genes in cardiac muscle, skeletal muscle, liver, and gonad of zebrafish (species with determinate growth) and tambacu (species with indeterminate growth). We observed a distinct expression of piwi1 and piwi2 between tambacu and zebrafish, with both genes more expressed in tambacu in all tissues evaluated. Piwi genes can represent potential candidates involved with indeterminate muscle growth control.
