Modulation of Duodenal TfR Expression in IDA Induced Rat with Date Palm and Goat Milk Intake

Abstract

Iron deficiency anemia (IDA) is a medical condition characterized by insufficient iron levels in the body, resulting in a reduced ability to produce hemoglobin (Hb), a critical component of red blood cells. IDA is often associated with chronic fatigue, impaired cognitive function, and diminished well-being. Transferrin (Tf) is one of the major proteins in iron homeostasis, responsible for transporting iron through the blood to various tissues, while its carrier protein, transferrin receptor (TfR), mediates the cellular uptake of transferrin-bound iron into the cell. This study aims to evaluate the expression of TfR mRNA and protein in the small intestine following intervention with date palm and goat milk in IDA-induced rats. Twenty-four male Wistar rats were induced with IDA for 2 weeks using a low-iron diet. Following IDA detection, rats were supplemented with date palm and goat milk, singly and in combination. After four weeks, the rats were sacrificed, and the expression of TfR mRNA and protein in the small intestine was assessed using qPCR and immunohistochemistry, respectively. Data were analyzed using SPSS 24.0, with a significance level set at p<0.05. Results demonstrated that date palm and goat milk significantly improved Hb, serum iron, Tf saturation levels, and modulated the expression of TfR mRNA in the IDA-induced rats. Expression of TfR on the crypt region and brush border membrane of the small intestine was normalized following intervention. The findings indicate that supplementation of date palm and goat milk improved Hb and Tf saturation levels and significantly modulated duodenal TfR expression in IDA-induced rats.
