Chaperones in Neurodegeneration.
UNLABELLED Cellular protein homeostasis (proteostasis) maintains the integrity of the proteome and includes protein synthesis, folding, oligomerization, and turnover; chaperone proteins assist with all of these processes. Neurons appear to be especially susceptible to failures in proteostasis, and this is now increasingly recognized as a major origin of neurodegenerative disease. This review, b...
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...
متن کاملMolecular Chaperones and Co-chaperones as Therapeutic Targets for Cancer
Cancer is a devastating disease that has affected millions of people, consumed tremendous efforts in the treatment/care and is incurable. Statistics from www.seer.cancer.gov show 14,140,254 people were living with cancer in 2013 in US with 1,685,210 new cases projected and 595,690 estimated deaths to occur due to cancer in 2016. Number of people surviving cancer (measured as 5-year survival rat...
