In contrast, Yasar et al. reported the lowest serum myostatin levels in KTRs (46.4 ± 21.6 ng/mL) compared to patients on hemodialysis, peritoneal dialysis, or with non-dialysis-dependent CKD (378.0 ± 122.6 ng/mL, 232.8 ± 97.6 ng/mL, 318.8 ± 217.9 ng/mL, respectively; p < 0.001) [20]. The gene discussed is MSTN; the disease is chronic kidney disease.
