Background: Type 2 Diabetes Mellitus (T2DM) is a metabolic disorder defined via elevated blood glucose caused by insufficiency of insulin-sensitive tissues to respond to insulin or defective insulin production by pancreatic β-cells due to environmental and genetic factors. Megalin is a glycoprotein that is mostly found in the proximal tubular cells, major role is to reabsorb albumin and other proteins that the glomerulus has filtered in the proximal tubules.Methods: The purpose of research measure the concentration of megalin and Neutrophil Gelatinase Associated Lipocalin (NGAL) in type 2 patients, in the period from December 2022 to March 2023 at the Baghdad Teaching Hospital120 participants aged(30-60) years, the measured concentration of Megalin, NGAL, and fasting blood glucose in serum and whole blood estimated for glycated hemoglobin (HbA1C).Results: The result indicates blood glucose concentration in patients with T2DM (344.975±63.68mg/dl) was significantly higher than control(106.62±12.59mg/dl), HbA1C (13.40±10.35%) in T2DM patients was significantly higher than control (4.310±0.336%), Megalin levels revealed for T2DM patients (220.70±42.47pg/ml) significantly higher than control (120.42±29.33pg/ml), NGAL(447.68±62.76pg/ml) in T2DM patients higher than control(264.93±51.79 pg/ml).Conclusion: According to the results NGAL and Megalin levels were significantly higher in T2DM patients as compared to controls play a role in diabetes pathogenesis and as biomarkers for the early identification of diabetic nephropathy.Keywords: Type 2 diabetes; Megalin; Neutrophil Gelatinase; Associated LipocalinEditorial Expression of Concern20 June 2025: Following publication of this paper, the internal audit (consequent to concerns on quality raised by Web of Science) notified Advancements in Life Sciences about insufficient peer review.
