Little evidence for mitochondrial DNA methylation

gettingwell4 2-3 stars Required further work, Epigenetics

This 2018 Japanese rodent study used three different techniques to detect mitochondrial DNA methylation: “Whilst 5-methylcytosine (5mC) is a major epigenetic mark in the nuclear DNA in mammals, whether or not mitochondrial DNA (mtDNA) receives 5mC modification remains controversial. We used bisulfite sequencing, McrBC digestion analyses and liquid chromatography mass spectrometry, which are distinctly differing … Continue reading Little evidence for mitochondrial DNA methylation

Mitochondria interface genetic/epigenetic responses to psychological stress

gettingwell4 2-3 stars Required further work, Cortisol, Dopamine, Epigenetics, Glutamate, Hippocampus, Hypothalamus, Limbic system, Neurochemicals, Serotonin, Stress , , ,

This 2015 Pennsylvania rodent study found: “Mitochondria can regulate complex whole-body physiological responses, impacting stress perception at the cellular and organismal levels. Mitochondrial dysfunctions altered the hypothalamic–pituitary–adrenal [HPA] axis, sympathetic adrenal–medullary activation and catecholamine levels, the inflammatory cytokine IL-6, circulating metabolites, and hippocampal gene expression responses to stress. Stress-induced neuroendocrine, inflammatory, metabolic, and transcriptional responses … Continue reading Mitochondria interface genetic/epigenetic responses to psychological stress

Broccoli sprouts activate the AMPK pathway

gettingwell4 4-5 stars Advanced knowledge, Epigenetics, Stress ,

I’ll curate this 2020 rodent study through its summary graphic and caption: “Type 2 diabetes exhibits elevated levels of circulating fatty acids and CD36. This results in excessive fatty acids binding with CD36 to suppress AMPK [adenosine 5′ monophosphate-activated protein kinase, a key player in regulating energy metabolism]. Inactivation of AMPK breaks homeostasis in lipid … Continue reading Broccoli sprouts activate the AMPK pathway

A case for carnitine supplementation

gettingwell4 4-5 stars Advanced knowledge, Brain development, Epigenetics, Immune system, Memory, Stress , , , , ,

This 2020 review subject was carnitine, acetyl-L-carnitine, and its other molecular forms: “Carnitine is necessary to deliver long-chain fatty acids from cytosol into mitochondria. Carnitine homeostasis is maintained by diet and renal absorption, as only a small amount (about 25%) is obtained by endogenous biosynthesis. Defective fatty acid oxidation occurs with reduced intracellular levels of … Continue reading A case for carnitine supplementation

Part 2 of Eat broccoli sprouts for your eyes

gettingwell4 4-5 stars Advanced knowledge, Epigenetics, Memory, Stress , ,

I was a little bothered by an unreferenced statement in Eat broccoli sprouts for your eyes that: “Once AGEs are formed, most are irreversible.” I searched curated 2020 studies for “revers” and found that recent blog studies favored reversibility of epigenetic changes 12-to-2. Do they reflect my selection bias, or is there something different about … Continue reading Part 2 of Eat broccoli sprouts for your eyes

DEET and permethrin cause transgenerational diseases

gettingwell4 5+ stars Premium, Epigenetics, Memory, Stress , , ,

This 2020 rodent study from the labs of Dr. Michael Skinner at Washington State University examined how great-grandmothers’ insect repellent exposures produced diseases in their great-grand offspring: “Permethrin and DEET are the pesticides and insect repellent most commonly used by humans. These pesticides have been shown to promote the epigenetic transgenerational inheritance of disease in … Continue reading DEET and permethrin cause transgenerational diseases

Treating psychopathological symptoms will somehow resolve causes?

This 2020 Swiss review subject was potential glutathione therapies for stress: “We examine the available data supporting a role for GSH levels and antioxidant function in the brain in relation to anxiety and stress-related psychopathologies. Several promising compounds could raise GSH levels in the brain by either increasing the availability of its precursors or the … Continue reading Treating psychopathological symptoms will somehow resolve causes?

Unraveling oxytocin – is it nature’s medicine?

This 2020 review attempted to consolidate thousands of research papers on oxytocin: “Chemical properties of oxytocin make this molecule difficult to work with and to measure. Effects of oxytocin are context-dependent, sexually dimorphic, and altered by experience. Its relationship to a related hormone, vasopressin, have created challenges for its use as a therapeutic drug. Widely … Continue reading Unraveling oxytocin – is it nature’s medicine?

Broccoli sprout synergies

gettingwell4 4-5 stars Advanced knowledge, Cortisol, Dopamine, Epigenetics, Glutamate, Hippocampus, Immune system, Limbic system, Memory, Neurochemicals, Stress , , , ,

I was asked for examples of broccoli sprout synergies with supplements mentioned in Week 19 of Changing to a youthful phenotype with broccoli sprouts. I take supplements and broccoli sprouts together an hour or two before meals to keep meal contents from lowering sulforaphane bioavailability. Sulforaphane peaks in plasma between 1 and 2 hours after … Continue reading Broccoli sprout synergies

Eat broccoli sprouts for your hair!

gettingwell4 4-5 stars Advanced knowledge, Acetylcholine, Epigenetics, Immune system, Memory, Neurochemicals, Stress, Testosterone , ,

This 2017 review explored broccoli sprout compounds effects on head hair: “Skin appendages, notably hair follicles (HFs), can be exposed to high levels of reactive oxygen species (ROS), which are generated through metabolic reactions occurring mostly in the mitochondria, peroxisomes and the endoplasmic reticulum as well as in the plasma membrane. Despite their involvement in … Continue reading Eat broccoli sprouts for your hair!

This 2019 Mexican review stated: “We describe some of the molecular and physical characteristics of SFN, its mechanisms of action, and the effects that SFN treatment induces in order to discuss its relevance as a ‘miraculous’ drug to prevent aging and neurodegeneration. SFN has been shown to modulate several cellular pathways in order to activate … Continue reading A review of sulforaphane and aging

Reversal of aging and immunosenescent trends with sulforaphane

gettingwell4 4-5 stars Advanced knowledge, Epigenetics, Immune system, Memory, Stress ,

Sulforaphane research findings have commonalities with a super informative presentation by the lead researcher of clinical trial Reversal of aging and immunosenescent trends. I did a PubMed search of sulforaphane and each presentation topic, and used a 1/1/2015 publication date cutoff. Presentation topics through the first 13 minutes were: Thymus – no recent sulforaphane studies … Continue reading Reversal of aging and immunosenescent trends with sulforaphane

To follow up A rejuvenation therapy and sulforaphane, the study’s lead laboratory researcher – Dr. Harold Katcher – 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 … Continue reading An environmental signaling paradigm of aging

Broccoli sprouts oppose effects of advanced glycation end products (AGEs)

gettingwell4 4-5 stars Advanced knowledge, Epigenetics, Hypothalamus, Immune system, Limbic system, Stress , , ,

This 2020 Australian/UK review subject was AGEs: “AGEs are formed during cooking and food processing or produced endogenously as a consequence of metabolism. Deleterious effects of AGEs are underpinned by their ability to trigger mechanisms well known to elicit metabolic dysfunction, including activation of inflammatory pathways, oxidative stress and impaired mitochondrial oxidative metabolism. They have … Continue reading Broccoli sprouts oppose effects of advanced glycation end products (AGEs)
