Tag: Reactive Oxygen Species

Nematode
A study published in Redox Biology has reported that the upregulation of thioredoxin, a fundamental part of mitochondrial defense against reactive oxygen species, is associated with longevity in mutant C. elegans worms. Free radicals, revisited Why we Age: Mitochondrial DysfunctionAs they age, the mitochondria in our cells lose their ability to provide cellular energy and...
Egg cell
A group of researchers has documented in Aging that Epitalon, a synthetic peptide made of four amino acids, slows the aging of egg cells (oocytes) after ovulation. Aging makes fertilization difficult Oocyte aging is well-known to lead to fertilization deficiencies and a host of other problems that are visible in the cells themselves, including abnormalities...
Cat and mouse
In a study conducted by scientists from Baylor College of Medicine in Houston, supplementation of glutathione had a drastic effect on the lifespan of wild-type mice, both male and female [1]. Dangerous species Oxidative stress happens when the delicate balance between the production and degradation of reactive oxygen species (ROS) is lost. This can be...
Killifish
A recent study published in Biogerontology has discovered a potential new aging biomarker and longevity therapeutic target [1]. Isthmin 1 (Ism1) in aging fish  Ism1 is not a well-known protein, but it has been shown to play a role in multiple aspects of biology. It contributes to tumor suppression [2,3], is essential during organ development...
Bifidobacterium
A new publication in Nature Aging has investigated the role of the gut bacteria Bifidobacterium adolescentis in aging and longevity. The Gut MicrobiomeThe gut microbiome is a complex and ever-changing ecosystem populated by a myriad of archaea, eukarya, viruses, and bacteria. Four microbial phyla, Firmicutes, Bacteroides, Proteobacteria, and Actinobacteria, make up 98% of the total...
Oxygen tank
Recent experiments published in the latest issue of Aging associate hyperbaric oxygen therapy with improvements in several biomarkers of skin aging. SkinSkin, as the most readily visible organ of the human body, is one of the first to let us know that we are getting older. Our skin goes beyond appearance; it protects our internal...
