Clinical trial for nicotinamide riboside: Vitamin safely boosts levels of important cell metabolite linked to multiple health benefits
University of Iowa Health Care, October 10, 2022
In a clinical trial of nicotinamide riboside (NR), a newly discovered form of Vitamin B3, researchers have shown that the compound is safe for humans and increases levels of a cell metabolite that is critical for cellular energy production and protection against stress and DNA damage.
Studies in mice have shown that boosting the levels of this cell metabolite — known as NAD+ — can produce multiple health benefits, including resistance to weight gain, improved control of blood sugar and cholesterol, reduced nerve damage, and longer lifespan. Levels of NAD+ diminish with age, and it has been suggested that loss of this metabolite may play a role in age-related health decline. These findings in animal studies have spurred people to take commercially available NR supplements designed to boost NAD+. However, these over-the-counter supplements have not undergone many clinical trials to see if they work in people.
The new research, reported in the journal Nature Communications, was led by Charles Brenner, PhD, professor and Roy J. Carver Chair of Biochemistry at the University of Iowa Carver College of Medicine
The human trial involved six men and six women, all healthy. Each participant received single oral doses of 100 mg, 300 mg, or 1,000 mg of NR in a different sequence with a seven-day gap between doses. After each dose, blood and urine samples were collected and analyzed to measure various NAD+ metabolites in a process called metabolomics. The trial showed that the NR vitamin increased NAD+ metabolism by amounts directly related to the dose, and there were no serious side effects with any of the doses.
“This trial shows that oral NR safely boosts human NAD+ metabolism,” Brenner says. “We are excited because everything we are learning from animal systems indicates that the effectiveness of NR depends on preserving and/or boosting NAD+ and related compounds in the face of metabolic stresses. Because the levels of supplementation in mice that produce beneficial effects are achievable in people, it appears than health benefits of NR will be translatable to humans safely.”
Consumption of a bioactive compound from Neem plant could significantly suppress development of prostate cancer
National University of Singapore, September 29, 2022
Oral administration of nimbolide, over 12 weeks shows reduction of prostate tumor size by up to 70 per cent and decrease in tumor metastasis by up to 50 per cent
A team of international researchers led by Associate Professor Gautam Sethi from the Department of Pharmacology at the Yong Loo Lin School of Medicine at the National University of Singapore (NUS) has found that nimbolide, a bioactive terpenoid compound derived from Azadirachta indica or more commonly known as the neem plant or curry leaf common in throughout Indian cuisine, could reduce the size of prostate tumor by up to 70 per cent and suppress its spread or metastasis by half.
In this research, we have demonstrated that nimbolide can inhibit tumor cell viability — a cellular process that directly affects the ability of a cell to proliferate, grow, divide, or repair damaged cell components — and induce programmed cell death in prostate cancer cells,” said Assoc Prof Sethi.
The researchers observed that upon the 12 weeks of administering nimbolide, the size of prostate cancer tumor was reduced by as much as 70 per cent and its metastasis decreased by about 50 per cent, without exhibiting any significant adverse effects. “This is possible because a direct target of nimbolide in prostate cancer is glutathione reductase, an enzyme which is responsible for maintaining the antioxidant system that regulates the STAT3 gene in the body. The activation of the STAT3 gene has been reported to contribute to prostate tumor growth and metastasis,” explained Assoc Prof Sethi. “We have found that nimbolide can substantially inhibit STAT3 activation and thereby abrogating the growth and metastasis of prostate tumor,” he added.
Mindfulness training provides a natural high, study finds
University of Utah, October 20, 2022
New research from the University of Utah finds that a mindfulness meditation practice can produce a healthy altered state of consciousness in the treatment of individuals with addictive behaviors. Not unlike what one might experience under the influence of psychedelic drugs—achieving this altered state through mindful meditation has the potential lifesaving benefit of decreasing one’s addictive behaviors by promoting healthy changes to the brain. The findings come from the largest neuroscience study to date on mindfulness as a treatment for addiction.
The study, published in the journal Science Advances, provides new insight into the neurobiological mechanisms by which mindfulness treats addiction. Study findings provide a promising, safe and accessible treatment option for the more than 9 million Americans misusing opioids. Eric Garland is the lead author of the paper and is a distinguished professor and directs the University of Utah’s Center on Mindfulness and Integrative Health Intervention Development.
Garland’s study builds on previous research measuring the positive effects of theta waves in the human brain. Researchers have found that individuals with low theta waves tend to experience a wandering mind, trouble concentrating or they ruminate on thoughts about themselves. Low theta waves result in a loss of self-control as the brain slips into its default mode of automatic habits. In contrast, when a person is focused, present and fully absorbed in a task, EEG scans will show increased frontal midline theta wave activity.
“With high theta activity, your mind becomes very quiet, you focus less on yourself and become so deeply absorbed in what you are doing that the boundary between yourself and the thing you are focusing on starts to fade away. You lose yourself in what you are doing,” said Garland.
Garland’s new study showed it is in this mindful, theta wave state that people begin to experience feelings of self-transcendence and bliss, and the brain changes in ways that actually reduce one’s addictive behaviors.
Garland’s research team recruited 165 adults with long-term opioid use for the study. Participants were randomly placed into either the control group that participated in supportive group psychotherapy or the experimental group taught to incorporate Mindfulness-Oriented Recovery Enhancement (MORE) into their daily lives.
Participants showed more than twice as much frontal midline theta brain activity following treatment with MORE, whereas those in supportive therapy showed no increase in theta. Participants in MORE who showed the biggest increases in theta waves reported more intense experiences of self-transcendence during meditation, including the sense of one’s ego fading away, a sense of oneness with the universe or feelings of blissful energy and love.
MORE also led to significant decreases in opioid misuse through the nine-month follow-up. These reductions in opioid misuse were caused in part by the increases in frontal midline theta brain waves. Garland explained that by achieving “tastes of self-transcendence” through meditation, mindfulness therapy boosted theta waves in the frontal lobes of the brain to help participants gain self-control over their addictive behaviors.
Free radicals blamed for toxic buildup in Alzheimer’s brains
Rutgers University, October 11, 2022.
A study reported in Cell Death & Disease revealed a previously unknown mechanism that may contribute to traumatic brain injury and Alzheimer’s disease. While a buildup of the protein amyloid-beta has been hypothesized to be the major driver of Alzheimer’s disease, the study suggests that another protein, after undergoing oxidation by free radicals, could be a causative factor.
“Indeed, scientists have known for a long time that during aging or in neurodegenerative disease cells produce free radicals,” explained lead researcher Federico Sesti, who is a professor of neuroscience and cell biology at Rutgers Robert Wood Johnson Medical School. “Free radicals are toxic molecules that can cause a reaction that results in lost electrons in important cellular components, including the channels.”
Dr Sesti and colleagues determined that oxidation of a potassium channel known as KCNB1 results in a toxic buildup of this protein, leading to increased amyloid-beta production and damage to brain function. “The discovery of KCNB1’s oxidation/build-up was found through observation of both mouse and human brains, which is significant as most scientific studies do not usually go beyond observing animals,” Dr Sesti reported. “Further, KCBB1 channels may not only contribute to Alzheimer’s but also to other conditions of stress as it was found in a recent study that they are formed following brain trauma.”
Study: Maternal, paternal exercise affects metabolic health in offspring
Ohio State University, October 19, 2022
A mouse study by Kristin Stanford, with The Ohio State University College of Medicine at the Wexner Medical Center, provides new ways to determine how maternal and paternal exercise improve metabolic health of offspring.
This study used mice to evaluate how their lifestyles—eating fatty foods vs. healthy and exercising vs. not—affected the metabolites of their offspring.
Metabolites are substances made or used when the body breaks down food, drugs or chemicals, or its own fat or muscle tissue. This process, called metabolism, makes energy and the materials needed for growth, reproduction and maintaining health. Metabolites can serve as disease markers, particularly for type 2 diabetes and cardiovascular disease.
“Tissue metabolites contribute to overall metabolism, including glucose or fatty acid metabolism, and thus systemic metabolism. We have previously shown that maternal and paternal exercise improve health of offspring. Tissue and serum metabolites play a fundamental role in the health of an organism, but how parental exercise affects offspring tissue and serum metabolites has not yet been investigated. This new data contributes to how maternal or paternal exercise could improve metabolism in offspring,” Stanford said.
This study found that all forms of parental exercise improved whole-body glucose metabolism in offspring as adults, and metabolomics profiling of offspring serum, muscle, and liver reveal that parental exercise results in extensive effects across all classes of metabolites in all of these offspring tissues.
Regular consumption of fried food before pregnancy increases risk of developing gestational diabetes
Kennedy Shriver National Institute of Child Health and Human Development, October 10, 2022
New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) shows that women who eat fried food regularly before conceiving are at increased risk of developing gestational diabetes during pregnancy.
Gestational diabetes (GDM) is a complication that can arise during pregnancy, and is characterised by abnormally high blood glucose during the pregnancy (especially in the final 3 months). It can lead to increased birthweight of the child, as well jaundice and other complications. When left untreated, it can cause complications or stillbirth. Women who have GDM are more likely to later develop full blown type 2 diabetes.
The authors included 21,079 singleton pregnancies from 15,027 women in the Nurses’ Health Study II (NHS II) cohort. NHS II is an ongoing prospective cohort study of 116,671 female nurses in the USA aged 25-44 years at the start of study.
For fried food consumption, participants were asked “how often do you eat fried food away from home (e.g. French fries, fried chicken, fried fish)?” and “how often do you eat food that is fried at home?” Both questions had four possible frequency responses: less than once per week, 1-3 times per week, 4-6 times per week, or daily. The researchers analysed fried food consumption at home and away from home separately, as well as total fried food consumption. In addition, they asked the participants what kind of frying fat/oils they usually used at home, with the possible responses as follows: real butter, margarine, vegetable oil, vegetable shortening, or lard.
The association persisted after further adjustments were made for varying body-mass index (BMI). After this, the risk ratios of GDM among women who consumed total fried foods 1-3, 4-6, and 7 or more times per week, compared with those who consumed less than once per week, were 1.06, 1.14, and 1.88 respectively (thus an 88% increased risk for 7 or more times per week compared with less than once per week).
The authors say: “The potential detrimental effects of fried food consumption on GDM risk may result from the modification of foods and frying medium and generation of harmful by-products during the frying process. Frying deteriorates oils through the processes of oxidation and hydrogenation, leading to an increase in the absorption of oil degradation products by the foods being fried, and also a loss of unsaturated fatty acids such as linoleic and linolenic acids and an increase in the corresponding trans fatty acids such as trans-linoleic acids and trans-linolenic acids.”
They add: “Frying also results in significantly higher levels of dietary advanced glycation end products (AGEs), the derivatives of glucose-protein or glucose-lipid interactions. Recently, AGEs have been implicated in insulin resistance, pancreatic beta-cell damage, and diabetes, partly because they promote oxidative stress and inflammation. Moreover, intervention studies with a diet low in AGEs have shown significantly improved insulin sensitivity, reduced oxidant stress, and alleviated inflammation.”
When analysed separately, the authors found that there was a statistically significant association of GDM with fried food consumption away from home, but not with fried food consumption at home. The authors say: “Deterioration of oils during frying is more profound when the oils are reused, a practice more common away from home than at home. This may partly explain why we observed a stronger association of GDM risk with fried foods consumed away from home than fried foods consumed at home.”
