Genomic imprinting and growth

This 2018 UK paper reviewed genomic imprinting: “Since their discovery nearly 30 years ago, imprinted genes have been a paradigm for exploring the epigenetic control of gene expression. Moreover, their roles in early life growth and placentation are undisputed. However, it is becoming increasingly clear that imprinted gene function has a wider role in maternal … Continue reading Genomic imprinting and growth

Genetic imprinting, sleep, and parent-offspring conflict

This 2016 Italian review subject was the interplay of genetic imprinting and sleep regulation: “Sleep results from the synergism between at least two major processes: a homeostatic regulatory mechanism that depends on the accumulation of the sleep drive during wakefulness, and a circadian self-sustained mechanism that sets the time for sleeping and waking throughout the … Continue reading Genetic imprinting, sleep, and parent-offspring conflict

A study of genetic imprinting and neurodevelopmental disorders

This 2016 UK human study assessed the roles of genetic imprinting on diseases that may originate from a certain interval on chromosome 15: “The 15q11.2-q13.3 region contains a cluster of imprinted genes, which are expressed from one parental allele only as a consequence of germline epigenetic events. The importance of epigenetic status of duplications at … Continue reading A study of genetic imprinting and neurodevelopmental disorders

Trapped, suffocating, unable to move – a Primal imprint

“The malady of needing to move constantly: organizing trips, making reasons to go here and there, and in general, keeping on the move..below all that movement is a giant, silent scream. The price we pay is never knowing our feelings or where they come from. We have the mechanism for our own liberation inside of … Continue reading Trapped, suffocating, unable to move – a Primal imprint

Take responsibility for your one precious life – DHEA

This 2020 meta-analysis subject was DHEA: “Twenty-four qualified trials were included in this meta-analysis. Statistically significant increases in serum IGF-1 levels were found only in participants who were: Women; or Supplementing 50 mg/d; or Undergoing intervention for > 12 weeks; or Without an underlying comorbidity; or Over the age of 60 years. DHEA supplementation led … Continue reading Take responsibility for your one precious life – DHEA

Take responsibility for your one precious life – Trained immunity

This 2020 review subject was the normal progression of our immune systems: “Age-related alterations in the immune system result in high susceptibility to infections, increased risk of hospitalization and mortality. Defects in adaptive immunity underlie the markedly low vaccine efficiency in the elderly. Despite reduced cellular functions, a systemic increase in inflammatory markers, so-called inflammaging, … Continue reading Take responsibility for your one precious life – Trained immunity

Reprogram inflammation with β-glucan

This 2020 French human cell study found: “Exposure of mononuclear phagocytes to β-glucan contributes to the induction of innate immune memory, which is associated with long-term epigenetic, metabolic, and functional reprogramming. We investigated how preincubation of human monocytes with particulate β-glucan affects the biological response of macrophages following NLRP3 inflammasome activation. Upon infection or cellular … Continue reading Reprogram inflammation with β-glucan

Transgenerational epigenetic inheritance of epimutations

My 600th curation is a 2020 rodent study from Dr. Michael Skinner’s labs at Washington State University: “Numerous environmental toxicants have been shown to induce the epigenetic transgenerational inheritance of disease and phenotypic variation. Alterations in the germline epigenome are necessary to transmit transgenerational phenotypes. In previous studies, the pesticide DDT and the agricultural fungicide … Continue reading Transgenerational epigenetic inheritance of epimutations

An environmental signaling paradigm of aging

To follow up A rejuvenation therapy and sulforaphane, the study’s lead laboratory researcher provided evidence for an environmental signaling paradigm of aging in this 2015 paper: “The age-phenotype of a cell or organ depends on its environment and not its history. Organ dysfunction is not the cause of aging, but is the result of its … Continue reading An environmental signaling paradigm of aging

A rejuvenation therapy and sulforaphane

The founder of the epigenetic clock methodology with the coauthor of Aging as an unintended consequence released a 2020 rodent study “Reversing age: dual species measurement of epigenetic age with a single clock” at https://www.biorxiv.org/content/10.1101/2020.05.07.082917v1.full.pdf: “We employed six clocks to investigate the rejuvenation effects of a plasma fraction treatment in different rat tissues. Two of … Continue reading A rejuvenation therapy and sulforaphane
