Transcriptomic profiling of the hypothalamus in a neonatal STZ-induced diabetes model: effects of Curcumin and Aged Garlic Extract.

This study aimed to characterize the hypothalamic transcriptomic signature in a complex murine model of T2DM induced by neonatal administration of Streptozotocin (nSTZ, 70 mg/kg) followed by a chronic High-Fat Diet (HFD, 60% kcal from fat).

Given the neuroprotective properties of natural polyphenols, we evaluated the modulatory effects of Curcumin (50 mg/kg) and Aged Garlic Extract (EAE, 200 mg/kg) administered daily via oral gavage for 28 days. By employing high-throughput RNA sequencing (RNA-seq), we identified differentially expressed genes (DEGs) and perturbed molecular pathways involved in neuroinflammation, synaptic plasticity and gabaergic system. Our findings provide a comprehensive map of the gene expression changes associated with diabetic neurodegeneration and the therapeutic potential of nutraceutical interventions to restore hypothalamic function.
