Proteostasis News and Research

RSS

Each mammalian cell contains up to 20,000 proteins, all of which must be maintained and regulated. Proteostasis is a complex pathway that functions to maintain all of the proteins within and around a cell.

ReSisTrace: Unveiling Pre-Existing Treatment Resistance in Cancer Cells

In many cancers, such as ovarian cancer, each round of chemotherapy kills the majority of cancer cells, while a small population of them survives through treatment.

Stanford study reveals how ribosomes may contribute to age-related diseases

Aging leads to a decline in cellular fitness and loss of optimal protein function. Many age-related ailments, including Alzheimer's and Parkinson's diseases, are caused by protein aggregation, a result of errors in protein folding.

New mouse line reveals the state of proteostasis in mammalian brain for the first time

Proteins are the "tools" of our cells – they are essential to all vital tasks. However, they are only able to do their jobs if they fold correctly and adopt their respective, very specific 3D structure.
