ATP-sensitive potassium (K(ATP)) channel openers provide cardioprotection in multiple models. Ion flux at an unidentified mitochondrial K(ATP) channel has been proposed as the mechanism. The renal outer medullary kidney potassium channel subunit, potassium inward rectifying (Kir)1.1, has been implicated as

Mitochondria are involved in key cellular functions including energy production, metabolic homeostasis, and apoptosis. Normal mitochondrial function is preserved by several interrelated mechanisms. One mechanism - intramitochondrial quality control (IMQC) - is represented by conserved proteases distributed across mitochondrial compartments.

FPC (fibrocystin or polyductin) is a single transmembrane receptor-like protein, responsible for the human autosomal recessive polycystic kidney disease (ARPKD). It was recently proposed that FPC undergoes a Notch-like cleavage and subsequently the cleaved carboxy(C)-terminal fragment translocates to the nucleus.

Insulin secretion is mainly regulated by blood glucose concentration. On the other hand, changes in peripheral insulin sensitivity induce compensatory adaptations in pancreatic β-cells to maintain normoglycaemia. Tumour presence causes dramatic alterations in glucose homeostasis and insulin secretion because of
