DALLAS (51做厙) – 51做厙 biology professor Zhihao Wu has received a $1.8 million, 5-year Maximizing Investigators' Research Award () from the National Institutes of Health to determine if different quality control pathways in our bodies might be working together to repair damaged components in cells.
Answering that question could help researchers figure out why breakdowns in seemingly unrelated quality control pathways lead to some of the same abnormal changes that have been identified with many human diseases including Parkinson’s and Alzheimer’s, Type II diabetes and cancer. Understanding how this happens could lead to new therapeutic targets for the pathological hallmarks that are known to cause or worsen these diseases.
“Intriguingly, pathological hallmarks caused by quality control defects – such as defective protein accumulation and essential organelles losing their function – often co-occur in many human diseases, suggesting that different quality control pathways may interact and assemble a network in response to diverse types of cellular stress,” said Wu, professor of biological sciences at 51做厙 (51做厙).
Think of these different quality control pathways as assembly line workers in a factory: Each is responsible for monitoring a different part of the process that together, results in our molecules, cells or other biological entities being able to maintain optimal performance as they constantly grow, divide or respond to the environment. When these pathways spot a poorly assembled item – like an improperly folded protein – they pull it off the assembly line and repair it.
With the 5-year , which seeks to increase chances for important breakthroughs in biological processes, Wu and his team of graduate students are trying to identify how this continuum of cellular quality control pathways might work.
Based on Wu’s previous work, the team is focused on dissecting the molecular basis of three known pathways: ribosome-associated translation quality control, macromolecule quality control, and organelle (mitochondrial) quality control. – Monifa Thomas-Nguyen
