One class of such sRNAs reduces long coding RNAs through a process called RNA disturbance that results in the silencing of the proteins that the long RNAs code for.Peter and colleagues have actually now determined very brief sequences present in some of these sRNAs that when present can kill cells by obstructing production of proteins required for cells to survive resulting in cell death. The guards numbers decrease with aging, therefore allowing the hazardous sRNAs to damage the cells.Key findingsThe amount of protective sRNAs is reduced in the aging brain.Adding back protective miRNAs partially safeguards brain cells crafted to produce less protective sRNAs from cell death induced by amyloid beta pieces (which trigger Alzheimers). How the research study worked: Scientists evaluated the brains of Alzheimers disease mouse models, the brains of young and old mice, caused pluripotent stem cell-derived neurons from normal people (both young and aged) and from Alzheimers clients, the brains of a group of older people over 80 with memory capacity comparable to people 50 to 60 years old, and multiple human brain-derived neuron-like cell lines treated with amyloid beta fragments, a trigger of Alzheimers.
