Cow milk causes disease

This 2021 review followed up Epigenetic effects of cow’s milk and many papers since then: “Epidemiological studies associate intake of cow milk with an increased risk of diseases, which are associated with overactivated mechanistic target of rapamycin complex 1 (mTORC1) signaling. Milk’s physiological function to maintain high mTORC1 signaling at the beginning of mammalian life … Continue reading Cow milk causes disease

Brown your white fat cells with broccoli sprouts

A 2021 rodent study and a blog post with 51 references investigated fat cells: “Sulforaphane (SFN) is a potent indirect antioxidant and a promising agent for controlling metabolic disorder disease. We evaluated efficacy of SFN against high fat diet (HFD)-induced-obesity mice, and investigated potential mechanisms. SFN: Suppressed HFD-induced body weight gain; Reduced fat cell [adipocyte] … Continue reading Brown your white fat cells with broccoli sprouts

All about the betaine

A trio of papers on betaine, the first being a 2021 series of thorough rodent experiments relating betaine and gut microbiota, and cause and effect: “Compared with lean individuals, adipose tissues in obese individuals secrete high levels of pro-inflammatory cytokines such as TNF-α, IL-1β, and IL-6, inducing: Systemic inflammation; Insulin resistance; Large amounts of carcinogenic … Continue reading All about the betaine

Clearing out the 2020 queue of interesting papers

I’ve partially read these 39 studies and reviews, but haven’t taken time to curate them. Early Life Intergenerational Transmission of Cortical Sulcal Patterns from Mothers to their Children (not freely available) Differences in DNA Methylation Reprogramming Underlie the Sexual Dimorphism of Behavioral Disorder Caused by Prenatal Stress in Rats Maternal Diabetes Induces Immune Dysfunction in … Continue reading Clearing out the 2020 queue of interesting papers

Eat broccoli sprouts for pain?

This 2018 study investigated pain-relieving effects of two broccoli sprout compounds, sulforaphane and chlorogenic acid: “Pharmacological evidence of the antinociceptive properties of broccoli aqueous extracts and bioactive metabolites were investigated in an experimental model of pain. It was found that sprouts produced better antinociceptive response than seeds and inflorescence of broccoli, where SFN [sulforaphane] and … Continue reading Eat broccoli sprouts for pain?

Sulforaphane and RNAs

This 2020 Texas review subject was long non-coding RNAs: “We review the emerging significance of long non-coding RNAs (lncRNA) as downstream targets and upstream regulators of the Nrf2 signaling pathway, a critical mediator of diverse cellular processes linked to increased cell survival. It is believed that more than 3% of human genes are regulated by … Continue reading Sulforaphane and RNAs

Eat broccoli sprouts today!

This 2020 Korean letter to a journal editor cited 23 recent papers in support of sulforaphane’s positive effects, mainly in anti-cancer treatments: “Gene expression is mediated by chromatin epigenetic changes, including DNA methylation, histone modifications, promoter-enhancer interactions, and non-coding RNA (microRNA and long non-coding RNA)-mediated regulation. Approximately 50% of all tumor suppressor genes are inactivated … Continue reading Eat broccoli sprouts today!

Clearing out the 2019 queue of interesting papers

I’m clearing out the below queue of 27 studies and reviews I’ve partially read this year but haven’t taken the time to curate. I have a pesky full-time job that demands my presence elsewhere during the day. :-\ Should I add any of these back in? Let’s be ready for the next decade! Early life … Continue reading Clearing out the 2019 queue of interesting papers

Epigenetic inheritance and microRNAs

This 2019 Canadian rodent study found: “Folic acid (FA) supplementation mitigates sperm miRNA profiles transgenerationally following in utero paternal exposure to POPs [persistent organic pollutants]. Across the F1 – F4 generations, sperm miRNA profiles were less perturbed with POPs + FA compared to sperm from descendants of dams treated with POPs alone..and only in F1 … Continue reading Epigenetic inheritance and microRNAs

Caloric restriction’s epigenetic effects

This 2019 US review subject was caloric restriction (CR) without malnutrition: “Cellular adaptation that occurs in response to dietary patterns can be explained by alterations in epigenetic mechanisms such as DNA methylation, histone modifications, and microRNA. Epigenetic reprogramming of the underlying chronic low-grade inflammation by CR can lead to immuno-metabolic adaptations that enhance quality of … Continue reading Caloric restriction’s epigenetic effects

Immune memory vs. immune adaptation

This 2019 Dutch/German/Romanian perspective aimed for a better understanding of immune systems: “Based on molecular, immunological, and evolutionary arguments, we propose that innate immune memory is a primitive form of immune memory present in all living organisms, while adaptive immune memory is an advanced form of immune memory representing an evolutionary innovation in vertebrates. Innate … Continue reading Immune memory vs. immune adaptation

Reversing epigenetic changes with CRISPR/Cas9

This 2018 Chinese review highlighted areas in which CRISPR/Cas9 technology has, is, and could be applied to rewrite epigenetic changes: “CRISPR/Cas9-mediated epigenome editing holds a great promise for epigenetic studies and therapeutics. It could be used to selectively modify epigenetic marks at a given locus to explore mechanisms of how targeted epigenetic alterations would affect … Continue reading Reversing epigenetic changes with CRISPR/Cas9

Epigenetic variations in metabolism

This 2018 German review was comprehensive for its subject, epigenetic control of variation and stochasticity in metabolic disease. I’ll focus on one aspect, phenotypic variation: “Phenotypic [Mendelian] variation can result both from gain- and loss-of-function mutations. Because of the extreme interconnectivity of cell regulatory networks, even at the cellular level, predicting the impact of a … Continue reading Epigenetic variations in metabolism

Transgenerational epigenetic effects of maternal obesity during pregnancy

This 2018 Belgian review subject was in part the transgenerational epigenetic effects of maternal obesity during pregnancy. The subject was tailored for the journal in which it appeared, Atherosclerosis, so other transgenerationally inherited epigenetic effects weren’t reviewed: “The transgenerational impact of these alterations in methylation patterns are only shown in animal studies with HFD [high-fat … Continue reading Transgenerational epigenetic effects of maternal obesity during pregnancy

The lack of oxygen’s epigenetic effects on a fetus

This 2018 Loma Linda review subject was gestational hypoxia: “Of all the stresses to which the fetus and newborn infant are subjected, perhaps the most important and clinically relevant is that of hypoxia. This review explores the impact of gestational hypoxia on maternal health and fetal development, and epigenetic mechanisms of developmental plasticity with emphasis … Continue reading The lack of oxygen’s epigenetic effects on a fetus
