In this study, by adenovirus-mediated delivery and inducible transgenic mouse models, we demonstrate the proliferation of both HCs and SCs by combined Notch1 and Myc activation in in vitro and in vivo inner ear adult mouse models. These proliferating mature SCs and HCs maintain their respective identities. Moreover, when presented with HC induction signals, reprogrammed adult SCs transdifferentiate into HC-like cells both in vitro and in vivo. Finally, our data suggest that regenerated HC-like cells likely possess functional transduction channels and are able to form connections with adult auditory neurons. Epigenetic Mutations Accumulate with Age, with Uncertain Consequences https://www.fightaging.org/archives/2019/12/epigenetic-mutations-accumulate-with-age-with-uncertain-consequences/ Epigenetic markers, such as methylation, determine the production rates of specific proteins in a cell. These epigenetic decorations to DNA change constantly, but many changes are characteristic of aging, which has led to the generation of epigenetic clocks in recent years. Epigenetic mutations are distinct from these changes, being effectively a form of stochastic damage in which methylation is inappropriately applied to a given location in the genome. Does this cause significant issues in aging? That is an open question, and can be considered in a similar way to the question of the effects of mutation to nuclear DNA. In most cases, random methylation won't have much of an...

AbstractPurposeGenetic variants may influence the pharmacokinetics and pharmacodynamics (PKPD) of cyclophosphamide (CY). CY plays a critical role in conditioning chemotherapy for hematopoietic cell transplantation (HCT), but its use is limited by toxicity. We explored the effect of genetic variants, potentially affecting PKPD of CY, and outcomes after HCT.MethodsThis observational pharmacogenomic study included 85 adults with hematologic malignancies who received reduced intensity conditioning with CY, fludarabine, and total body irradiation. We collected recipient DNA prior to HCT and evaluated 97 candidate variants in 66...
