Is translationally controlled tumour protein ( TCTP ) a novel glucose-regulated protein that is important for survival of pancreatic beta cells?
Regulation of TCTP protein levels by glucose is likely to be an important cyto-protective mechanism for pancreatic beta cells against damage caused by hyperglycaemia. In contrast, high concentration of palmitate causes cell stress, reduction in TCTP levels and consequently reduced cell viability. Our results imply that TCTP levels influence the sensitivity of beta cells to apoptosis.
Left ventricular function is normal, but changes in RV structure and function are demonstrable 20 years after surgical closure of VSD. The mechanisms and implications for these findings justify a further study in this increasingly large population of adult survivors of early surgery.
