Allergies and epigenetic histone modifications

This 2018 German review provided short summaries of 44 studies on the contribution of histone modifications to allergies. An overall summary of their search results was: “There are at least two levels at which the role of histone modifications is manifested. One is the regulation of cells that contribute to the allergic inflammation (T cells … Continue reading Allergies and epigenetic histone modifications

An overlooked gut microbiota product

This 2021 review subject was histone crotonylation: “Histone crotonylation is a newly identified epigenetic modification that has a pronounced ability to regulate gene expression. It belongs to an expanding group of short chain lysine acylations that also includes the extensively studied mark histone acetylation. Histone Kcr was first identified in 2011 where it was found … Continue reading An overlooked gut microbiota product

Benefits of eating fermentable fiber

This 2021 review subject was effects of short-chain fatty acids produced by gut microbiota: “SCFAs are the main players in the interplay between diet, microbiota, and health. SCFAs contribute to intestinal homeostasis and regulation of energy metabolism. SCFAs regulate the blood–brain barrier and neuroimmunoendocrine functions. During gestation, SCFAs can cause epigenetic imprinting and protect against … Continue reading Benefits of eating fermentable fiber

A bat epigenetic clock

This 2021 study subject was bats: “Exceptionally long-lived species, including many bats, rarely show overt signs of aging, making it difficult to determine why species differ in lifespan. Here, we use DNA methylation (DNAm) profiles from 712 known-age bats, representing 26 species, to identify epigenetic changes associated with age and longevity. Hypermethylated age- and longevity-associated … Continue reading A bat epigenetic clock

Eat broccoli sprouts for your heart

This 2021 rodent study investigated mechanisms of sulforaphane’s persistent cardiac protection: “Sulforaphane (SFN) reduced Ang II‐induced CpG hypermethylation and promoted Ac‐H3 [histone H3 acetylation] accumulation in the Nrf2 promoter region, accompanied by inhibition of global DNMT [DNA methyltransferase] and HDAC [histone deacetylase] activity, and a decreased protein expression of key DNMT and HDAC enzymes. SFN … Continue reading Eat broccoli sprouts for your heart

Reversing osteoporosis with Nrf2

This 2021 rodent study made old females out of young females by removing their ovaries, which induced osteoporosis. They then demethylated the Nrf2 gene promoter with exercise, increasing its expression, which reversed osteoporosis: “Nrf2 repression due to aberrant Dnmt elevation and subsequent Nrf2 promoter hypermethylation is an important epigenetic feature of osteoporosis (OP) pathogenesis. Ovariectomized … Continue reading Reversing osteoporosis with Nrf2

Choosing your future with β-glucan

This 2020 rodent study investigated yeast cell wall β-glucan effects on bacterial infections: “β-glucan is a potent inducer of epigenetic and functional reprogramming of innate immune cells, a process called trained immunity, resulting in an enhanced host response against secondary infections. We investigate whether β-glucan exposure confers protection against pulmonary Mycobacterium tuberculosis (Mtb) infection. β-glucan … Continue reading Choosing your future with β-glucan

Long-lasting benefits of a common vaccine

This 2021 review subject was effects of the 100-year-old tuberculosis vaccine: “Bacillus Calmette-Guerin (BCG) vaccine is one of the most widely used vaccines. It protects against many non-mycobacterial infections secondary to its nonspecific immune effects. The mechanism for these effects includes modification of innate and adaptive immunity. BCG vaccine is known to not only boost … Continue reading Long-lasting benefits of a common vaccine

Eat broccoli sprouts for depression

This 2021 rodent study investigated sulforaphane effects on depression: “Activation of Nrf2 by sulforaphane (SFN) showed fast-acting antidepressant-like effects in mice by: Activating BDNF; Inhibiting expression of its transcriptional repressors (HDAC2 [histone deacetylase 2, a negative regulator of neuroplasticity], mSin3A, and MeCP2); and Revising abnormal synaptic transmission. In a mouse model of chronic social defeat … Continue reading Eat broccoli sprouts for depression

Treat your gut microbiota as one of your organs

Two 2021 reviews covered gut microbiota. The first was gut microbial origins of metabolites produced from our diets, and mutual effects: “Gut microbiota has emerged as a virtual endocrine organ, producing multiple compounds that maintain homeostasis and influence function of the human body. Host diets regulate composition of gut microbiota and microbiota-derived metabolites, which causes … Continue reading Treat your gut microbiota as one of your organs

A broccoli sprouts study that lacked evidence for human applicability

A 2020 study Combined Broccoli Sprouts and Green Tea Polyphenols Contribute to the Prevention of Estrogen Receptor–Negative Mammary Cancer via Cell Cycle Arrest and Inducing Apoptosis in HER2/neu Mice (not freely available) conclusion was: “Lifelong BSp [broccoli sprouts] and GTP [green tea polyphenol] administration can prevent estrogen receptor–negative mammary tumorigenesis through cell cycle arrest and … Continue reading A broccoli sprouts study that lacked evidence for human applicability

Part 2 of The transgenerational impact of Roundup exposure

This 2020 study followed up The transgenerational impact of Roundup exposure using the Washington State Unversity research group’s most recent methodology in DEET and permethrin cause transgenerational diseases: “The herbicide glyphosate has been shown to promote epigenetic transgenerational inheritance of pathology and disease in subsequent great-grand offspring (F3 generation). The current study was designed to … Continue reading Part 2 of The transgenerational impact of Roundup exposure

Nrf2 and Parkinson’s disease

This 2020 rodent study investigated a long non-coding RNA (lncRNA) in Parkinson’s disease: “Knockdown of MALAT1 (metastasis-associated lung adenocarcinoma transcript 1) lncRNA inhibited elevated nuclear factor (erythroid-derived 2)-like-2 factor (NRF2) expression, thereby inhibiting inflammasome activation and ROS (reactive oxygen species) production. MALAT1 was shown to promote neuroinflammation by recruiting enhancer of zeste homologue 2 (EZH2) … Continue reading Nrf2 and Parkinson’s disease

Eat broccoli sprouts to pivot your internal environment’s signals

Two 2020 reviews covered some aspects of a broccoli sprouts primary action – NRF2 signaling pathway activation: “Full understanding of the properties of drug candidates rely partly on the identification, validation, and use of biomarkers to optimize clinical applications. This review focuses on results from clinical trials with four agents known to target NRF2 signaling … Continue reading Eat broccoli sprouts to pivot your internal environment’s signals

Jet fuel exposure causes diseases in the great-grand offspring

This 2020 Washington State University rodent study examined how great-grandmothers’ JP-8 exposures produced diseases in their great-grand offspring: “Ancestral exposure to environmental influences such as toxicants, abnormal nutrition, and traumatic stress can affect the germline epigenome and promote the epigenetic transgenerational inheritance of adult onset disease in various organisms from plants to humans. Biological mechanisms … Continue reading Jet fuel exposure causes diseases in the great-grand offspring
