Prior studies have shown that the double N-methylated analogue of islet amyloid polypeptide (IAPP) IAPP-GI, which is a conformationally constrained IAPP analogue mimicking a non-amyloidogenic IAPP conformation, is capable of blocking cytotoxic self-assembly of Ab. IAPP is a 37‐residue peptide hormone synthesized by the pancreatic β‐cells [ 2 ] . Prevention and treatment information (HHS). Epidemiological studies suggest BPA exposure is positively associated with the incidence of T2DM, which may be due to the exacerbated toxic aggregation of hIAPP induced by BPA as we previously reported. Epub 2016 Feb 27. islet amyloid polypeptide (hIAPP or amylin) is a polypeptide hormone produced in the pancreatic β-cells that plays a role in glycemic control. Uppsala: Acta Universitatis This pathological characteristic is most probably of great importance for the development of the β-cell failure in this disease ( 146 , 171 ), but the molecule also has regulatory properties in normal physiology. BPs analogues including bisphenol A (BPA), bisphenol B (BPB), bisphenol F (BPF), bisphenol S (BPS), bisphenol AF (BPAF), bisphenol AP (BPAP), tetrabromobisphenol A (TBBPA) and tetrachlorobisphenol A (TCBPA) are widely used in the production of plastic materials.
