    Abstract : The insulin concentration in blood varies periodically, which is believed to prevent down-regulation of the hormone receptors. Loss of the regular insulin oscillations is considered to be an early sign of developing diabetes. READ MORE

    Abstract : ATP-sensitive K+ (KATP) channels are widely distributed in a variety of tissues and cell types. KATP channels are comprised of two subunits, a pore forming subunit (Kir6.x) and a regulatory sulfonylurea receptor (SURx). Both subunits are required for fully functional channels. READ MORE
