Mini-Chaperones for Early AMD.
This issue of IOVS presents a novel strategy to develop treatment for nonexudative age-related macular degeneration (dry AMD) that derives from the natural, protective response of RPE cells to cellular stress. Oxidative stress is implicated in AMD pathogenesis and results in the upregulation of small heat shock proteins that act as molecular chaperones to prevent cellular apoptosis and minimize...
متن کاملRefolding chromatography with immobilized mini-chaperones (proteinyrenaturationyfoldingyGroELyhsp60)
Mini-chaperones (e.g., a peptide consisting of residues 191-345 of GroEL) that are immobilized on agarose have very efficient chaperoning activity with several proteins that are otherwise recalcitrant to renaturation by conventional methods. We have used immobilized mini-chaperones both in column chromatography and batchwise to renature an insoluble protein from an inclusion body, to refold app...
متن کاملExtracellular chaperones.
The maintenance of the levels and correct folding state of proteins (proteostasis) is a fundamental prerequisite for life. Life has evolved complex mechanisms to maintain proteostasis and many of these that operate inside cells are now well understood. The same cannot yet be said of corresponding processes in extracellular fluids of the human body, where inappropriate protein aggregation is kno...
متن کاملMolecular Chaperones
In most cases proteins fold spontaneously under physiological conditions and do not require any external assistance. This has become evident since the experiments on ribonuclease A conducted by Anfinsen in ‘50s and ‘60s. The list of such “successful” folders has grown since and now includes many two-state proteins catalogued in Folding & Design 3, R81. These proteins fold rapidly and reliably t...
متن کاملSpecialized chaperones
A n interphase meeting between X chromosomes, revealed by Na Xu, Chia-Lun Tsai, and Jeannie Lee (Harvard Medical School, Boston, MA), ensures that one and only one is silenced. Silencing of one of the two X chromosomes in a female somatic cell brings the gene dosage level down to that of male cells. Inactivation is controlled by several noncoding RNAs transcribed from, and acting in cis upon, t...
