The Role of Oestrogen Receptor Beta (ERβ) in the Aetiology and Treatment of Type 2 Diabetes Mellitus

Introduction: Challenges facing the treatment of type 2 diabetes necessitate the search for agents which act via alternative pathways to provide better therapeutic outcomes. Recently, an increasing body of evidence implicates the activation of oestrogen receptors (ERα and ERβ) in the development and treatment of underlying conditions in type 2 diabetes. This article summarizes available evidence for the involvement of oestrogen receptors in insulin secretion, insulin resistance as well as glucose uptake and highlights the potential of ERβ as a therapeutic target. Background: Recent studies indicate an association between the activation of each of the isoforms of ER and recent findings indicate that ERβ shows promise as a potential target for antidiabetic drugs. In vitro and in vivo studies in receptor knockout mice indicate beneficial actions of selective agonists of ERβ receptor and underscore its therapeutic potential. Conclusion: Studies are needed to further elucidate the exact mechanism underlying the role of ERβ activation as a therapeutic approach in the management of type 2 diabetes

Neuro-protective and Neuro-curative effect of Vernonia Amygdalina in rat model of neurodegenerative disease

Background: In this study, we assessed the protective potential of Vernonia amygdalina methanolic extract on aluminum chloride- induced neurotoxicity damage in Wistar rats. Methodology: Forty Adult female Wistar rats weighing (109 ± 16 g) were randomly divided into four (4) groups (A-D, of 10 rats respectively). Group A rats served as the normal control (treated with 5 mL/kg normal saline) for 28 days, Group B rats received 0.43 mL/kg Aluminum chloride (AlCL3) via oropharyngeal cannula for 14 days and 1.31 mL of Vernonia amygdalina extract after AlCL3 treatment for 14days, Group C rats received 1.31 mL of Vernonia amygdalina (VA) extract for 14 days and 0.43 mL/kg AlCL3 after VA treatment for 14 days, D rats received only 0.43 mL/kg Aluminum chloride (AlCL3) via oropharyngeal cannula for 14 days. The rats were sacrificed, and the hippocampus processed using Haematoxylin and Eosin (H&E) and Cresyl fast violet. Results: Results showed a significant (P ≤ 0.05) increase in body weight of groups B-D rats when compared to group A rats. Histological examinations showed clumpy of cell neurons, condensed pyramidal cells, necrotic and vascular edema and scanty neurofibrillary tangle which was an indication of neurodegeneration in the other groups when compared to the control group. Conclusion: that the oral administration of aluminum chloride could induce brain damage which may impair memory and learning as seen in Alzheimer disease and can be ameliorated with Vernonia Amygdalina leaf extract
