SelW is widely distributed in tissues of mammals with the
greatest quantities in skeletal muscle [16, 25, 26]. The
regulation of SelW by dietary Se was firstly described in
rats, and it became dramatically decreased in skeletal
muscles of Se-deficient animals . SelW levels in
all tissues of sheep except that in brain are sensitive to
selenium status . And this selenoprotein in rodents [28],
pigs , and primates are also generally
sensitive to Se status, indicating that it may play a role in
the metabolism of muscle tissues. However, the regulation
of SelW by Se is different for various tissues and differs
among different species
