Protein action in nature is generally controlled by the amount of protein produced and by chemical modification of the protein, and both are often perturbed in cancer. The amino acid side chains and the peptide and disulphide bonds that bind

In the 70s, the amino acid taurine was found essential for photoreceptor survival. Recently, we found that taurine depletion can also trigger retinal ganglion cell degeneration both in vitro and in vivo. Therefore, evaluation of taurine levels could be a

Renal proximal tubules are highly sensitive to ischemic and toxic insults and are affected in diverse genetic disorders, of which nephropathic cystinosis is the most common. The disease is caused by mutations in the CTNS gene, encoding the lysosomal cystine

Forkhead box O (FOXO; DAF-16 in worms) transcription factors, which are of vital importance in cell-cycle control, stress resistance, tumor suppression, and organismal lifespan, are largely regulated through nucleo-cytoplasmic shuttling. Insulin signaling keeps FOXO/DAF-16 cytoplasmic, and hence transcriptionally inactive. Conversely
