This 2020 human cell study elaborated on mechanisms mentioned in Eat broccoli sprouts for your hearing and Sulforaphane in the Goldilocks zone: “NFE2L2/NRF2, a transcriptional factor that controls expression of multiple detoxifying enzymes through antioxidant response elements (AREs), is a target of sulforaphane (SFN). NFE2L2/NRF2 is a target gene of TFEB (transcription factor EB), a … Continue reading Precondition your defenses with broccoli sprouts
Two 2021 papers, both of which I found by each citing a 2009 Molecular mechanisms underlying cochlear degeneration in the tubby mouse and the therapeutic effect of sulforaphane (not freely available). First was a review: “Hair cell damage and loss mediated by oxidative stress are important causes of hearing loss. Sensorineural hearing loss is the … Continue reading Eat broccoli sprouts for your hearing
This 2020 cell study investigated sulforaphane and three transcription pathways: “Novel findings of this study are: AMPK controls only a subset within the Nrf2-dependent transcriptome; Altered Nrf2 levels or altered accessibility of regulatory ARE sites do not account for observed differences in target gene transcription between used wt and AMPK −/− cells; Rather, AMPK presence/activity … Continue reading Part 3 of Broccoli sprouts activate the AMPK pathway
This 2020 rodent study investigated effects of different diets: “The present study aimed to evaluate effects of β-glucan on the microbiota gut-brain axis and cognitive function in an obese mouse model induced by a high-fat and fiber-deficient diet (HFFD). After long-term supplementation for 15 weeks, β-glucan prevented HFFD-induced cognitive impairment, assessed behaviorally by object location, novel … Continue reading Eat oats and regain cognitive normalcy
This 2020 food chemistry review provided phenolic-compound reasons to eat oats: “Phenolamides result from the conjugation of hydroxycinnamic acids with amines. These products contain a variety of metabolic, chemical, and functional capabilities due to the large number of possible combinations among the parent compounds. Of the currently known phenolamides, the most common are avenanthramides (AVAs), … Continue reading Eat oats today!
This 2020 review subject concerned a leading cause of blindness: “Advanced glycation end products (AGEs) are toxic compounds that have adverse effects on many tissues including the retina and lens. AGEs promote formation of reactive oxygen species (ROS), which, in turn, boost production of AGEs, a vicious cycle. Diabetic retinopathy (DR) is a devastating microvascular … Continue reading Eat broccoli sprouts for your eyes
This 2020 paper reviewed hormetic effects of a broccoli sprout compound: “Sulforaphane (SFN) induces a broad spectrum of chemoprotective effects across multiple organs that are of importance to public health and clinical medicine. This chemoprotection is dominated by hormetic dose responses that are mediated by the Nrf2/ARE pathway and its complex regulatory interactions with other … Continue reading Sulforaphane in the Goldilocks zone
Ever heard about AGEs? Here are three papers that describe how AGEs affect humans. First is a 2020 Italian review Common Protective Strategies in Neurodegenerative Disease: Focusing on Risk Factors to Target the Cellular Redox System: “Neurodegenerative disease is an umbrella term for different conditions which primarily affect the neurons in the human brain. Currently, … Continue reading Get serious about advanced glycation end products (AGEs)
This 2020 Swiss review subject was the interaction of Nrf2 activators and skin: “The electrophile and Nrf2 activator dimethyl fumarate (DMF) is an established and efficient drug for patients suffering from the common inflammatory skin disease psoriasis. DMF is being tested for pharmacological activity in several other inflammatory skin conditions. Psoriasis is a chronic inflammatory … Continue reading Eat broccoli sprouts for your skin!
This 2020 US human study investigated autism improvements with sulforaphane: “Autism Spectrum Disorder (ASD) is one of the most common neurodevelopmental disorders that, in the United States, is currently estimated to affect 1 out of 59 children who are 8 years old. Despite decades of research and advances in our knowledge of etiologies of ASD, … Continue reading Autism biomarkers and sulforaphane
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
This 2019 McGill review discussed long-lasting effects of perinatal stress: “Epigenetic processes are involved in embedding the impact of early-life experience in the genome and mediating between social environments and later behavioral phenotypes. Since these phenotypes are apparent a long time after early experience, changes in gene expression programming must be stable. Although loss of … Continue reading The epigenetics of perinatal stress
This 2019 McGill rodent study found: “Prenatal stress exacerbates pain after injury. Analysis of mRNA expression of genes related to epigenetic regulation and stress responses in the frontal cortex and hippocampus, brain structures implicated in chronic pain, showed distinct sex and region-specific patterns of dysregulation. In general, mRNA expression was most frequently altered in the … Continue reading Prenatal stress heightened adult chronic pain
This 2019 German human study found: “A critical role of BDNF [brain-derived neurotrophic factor] methylation in human amygdala response to negative emotional stimuli, whereby: High BDNF methylation rates were for the first time shown to be associated with a high reactivity in the amygdala; and High BDNF methylation and high amygdala reactivity were associated with … Continue reading Emotional responses and BDNF methylation
This 2019 Germany/Canada human fetal cell study was a Proceedings of the National Academy of Sciences of the United States of America direct submission: “In a human hippocampal progenitor cell line, we assessed the short- and long-term effects of GC [glucocorticoid] exposure during neurogenesis on messenger RNA expression and DNA methylation profiles. Our data suggest … Continue reading PNAS politics in the name of science
