Serum Meteorin-like protein levels decreased in patients newly diagnosed with type 2 diabetes

We analyzed circulating Meteorin-like (METRNL) levels in human. Serum METRNL levels were significantly lower in subjects with diabetes mellitus compared with those without diabetes. Serum METRNL was negatively correlated with the serum glucose level and insulin resistance. Metformin treatment did not increase the serum METRL levels after 12 weeks.
