SUZHOU, China - Aug. 9, 2020 - PRLog -- Re-Stem Biotech (Re-Stem or the Company), a biotechnology firm engaged in the research and development of cell therapies targeting osteoarthritis, spinal cord injury and various cancers recently funded in part a study titled "Solid-phase inclusion as a mechanism for regulating unfolded proteins in the mitochondrial matrix". Researchers at The Johns Hopkins University School of Medicine, led by Rong Li, Ph.D., published their findings in the journal "Science Advances" (view full article here: https://advances.sciencemag.org/
About Mitochondrial Dysfunction
Mitochondrial dysfunction is a hallmark of age-related diseases, such as cardiovascular diseases and neurodegenerative diseases. During aging, damaged/unfolded proteins in mitochondria that are failed to be degraded gradually accumulate. In addition, recent evidence suggests that non-mitochondrial proteins constituting pathological aggregates in neurodegenerative diseases also accumulate in mitochondria and cause mitochondrial dysfunction. However, it remains unclear how excessive damaged proteins are managed within mitochondria when known quality control mechanisms become inadequate, and how they contribute to mitochondrial dysfunction during the aging process.
About the Study
The researchers discovered that excessive unfolded proteins in the mitochondrial matrix are consolidated into novel structures, which they named Deposits of Unfolded Mitochondrial Proteins (DUMP). DUMP formation is an age-dependent process, while accelerated DUMP formation causes mitochondrial dysfunction and premature aging. They found that DUMP formation was not random, but specific in mitochondria near endoplasmic reticulum (ER), another organelle in cells. The contact sites between mitochondria and ER regulate DUMP formation via transferring lipids between two organelles. Via a series of genetic and live-cell imaging studies, researchers identified key enzymes of mitochondrial lipid metabolism that control DUMP formation. Manipulation of these enzymes modulates DUMP formation, therefore, potentially they could be targets for anti-aging or treating age-related diseases.
