Diabetic kidney disease is the leading worldwide cause of end stage kidney disease and a growing public health challenge.
The unfolded protein response (UPR) is a homeostatic pathway that regulates endoplasmic reticulum (ER) membrane structure and secretory function.
The UPR reduces protein synthesis, augments the ER folding capacity and downregulates m RNA expression of genes by multiple pathways.
Aberrant activation of ER stress can also induce inflammation and cellular apoptosis, and modify signaling of protective processes such as autophagy and m TORC activation.
Congenital heart disease places a significant burden on the individual, family and community despite significant advances in our understanding of aetiology and treatment.
The diabetic kidney is exposed to many environmental stressors and each cell type has developed intricate signaling systems designed to restore optimal cellular function.
Several models have been used to investigate the mechanisms by which the extra copy of chromosome 21 leads to the DS phenotype.
In the last five years, several laboratories have been successful in reprogramming patient cells carrying the trisomy 21 anomaly into induced pluripotent stem cells, i.e., T21-i PSCs.
This finding, together with promising case studies in the paediatric setting, demonstrates the potential for this treatment in congenital heart disease.
Furthermore, induced pluripotent stems cell technology, provides a unique opportunity to address aetiological, as well as therapeutic, aspects of disease.
