- Abstract
- Minocycline is a semi-synthetic tetracycline derivative antibiotic that has been examined for its non-antibiotic properties, such as anti-inflammatory, tumor-suppressive, and neuroprotective effects. In this study, we found that feeding minocycline to Drosophila improves proteostasis during organismal aging. Poly-ubiquitinated protein aggregates increase in the flight muscles as flies age, which are reduced in response to minocycline feeding. Minocycline feeding increases the expression of several autophagy genes and the activity of the autophagy/lysosomal pathway in Drosophila muscles. Interestingly, mutant flies lacking either FOXO or Hsp70 showed increased levels of poly-ubiquitinated protein aggregates with reduced autophagy/lysosomal activity, which was not reversed by minocycline feeding. Our findings suggest that minocycline may improve proteostasis in aging tissues via FOXO-Hsp70 axis, which highlights the multifaceted effects of minocycline as a therapeutic agent in age-associated features. © 2022
