“A 2021 study out of Japan showed how targeting genes can regrow teeth in animals. Now, the team has turned to a human clinical trial. By targeting the USAG-1 gene, researchers believe that they can help people without a full set of teeth regrow teeth. The team says that humans have a third set of teeth available as buds, ready to grow as needed.” #dna #isogg #epigenetics #geneadons https://www.popularmechanics.com/science/health/a44786433/humans-have-third-set-teeth/

“Scientists believe that an evolutionary bottleneck might have been caused by an extreme climate event, which they estimate left just 1,280 breeding individuals of our ancestors for about 117,000 years.

“Nandakumar and his team, including senior scientist Valerie Tesmer, showed that a shelterin protein called POT1 uses a cavity the researchers call the "POT-hole" to hide the natural end of the chromosome from being recognized as DNA damage by the ATR machinery. The study is published in the journal Science.
"We dedicate this to the roads in Michigan—not all POT-holes are bad," Nandakumar said.” #isogg #dna #epigenetics #geneadons

“The electricity generated non-toxic levels of reactive oxygen species, energetic molecules that – when properly managed – can start a process that activates cells engineered to respond to the change in chemistry. Changing how the cell's DNA is regulated by messing with their epigenetic 'on/off switch' molecules can potentially helping with a variety of conditions affected by genetics.” #isogg #dna

“The HLD 6 mandible provides further support for the high morphological diversity during late Middle Pleistocene hominin evolution.

“This is the first time that we could have a set of DNA sequences of pathogens present at a single location, and in parallel, DNA changes in the local populations,” Robert Tykot, professor of anthropology at the University of South Florida, said in a statement. “Thus, we can study for the first time, the co-evolution of pathogens and humans, unhindered by the fast mutations of modern viruses or the presence of vaccinated people.” #isogg #dna #geneadons https://www.iflscience.com/welcome-to-venices-plague-island-home-to-thousands-of-skeletons-69944

“The results revealed a particular epigenetic signature in memory cells, resulting in rapid activation of crucial set of genes compared to naïve cells. These genes were more accessible to the cellular machinery, in particular to a family of transcription factors called AP-1. To put it into a racing context: these genes have been warming-up ever since the cell's first contact with the antigen.” #isogg
