Immune Response Against Skin-dwelling Viruses Stops Cancer

Viruses get a bad rap as potential cancer-causers, but at least one class of viruses that commonly live on human skin - so-called "low-risk" human papillomaviruses - appear to play an unwitting role in protecting us against skin cancer according to a new study published in Nature. Patients who have immune systems that are suppressed from diseases or medical therapy are at greatly increased risk for cancers linked to viral infections, particularly squamous cell carcinoma (SCC) of the skin. Although multiple studies have tried to show a link between human papillomavirus (HPV) infections and SCC, none have been able to show that HPVs actually drive the development of these common skin cancers, say Shawn Demehri, MD, PhD investigator in the Center for Cancer Immunology at Massachusetts General Hospital (MGH) department of Dermatology and the MGH Cancer Center, and colleagues. Instead, working with experimental models and tissue samples from human skin cancer, they found that the presence of "commensal" papillomaviruses - low-risk forms of HPV that dwell on the skin of a large majority of people - appears to have an indirect protective rather than harmful effects against SCC. "This is the first evidence that commensal viruses could have beneficial health effects both in experimental models and also in humans, and it turns out that this beneficial effect has to do with cancer protection. The role of these commensal viruses, in this case papillomaviruses, is to induce immunity that then is protecting patients from skin cancers," he says. https://www.technologynetworks.com/cancer-research/news/immune-response-against-skin-dwelling-viruses-stops-cancer-326626?utm_campaign=NEWSLETTER_TN_Breaking%20Science%20News&utm_source=hs_email&utm_medium=email&utm_content=78793302&_hsenc=p2ANqtz-9FyKGcjw68GgKrX9Kkb1qNHTItm60pPw9PPOkjLw2hsqYMp-LqWQlrQlx6TBvlk03jhArzOBT3bQZaboOrpq1FOfJtKA&_hsmi=78793302

Healthcare Workers Among The “Hardest Hit” By Sleep Deprivation, Study Suggests

“The number of working Americans who get less than seven hours of sleep a night is on the rise. And the people hardest hit when it comes to sleep deprivation are those we depend on the most for our health and safety: police and health care workers.” A recent study published in the Journal of Community Health “found the prevalence of inadequate sleep, defined as seven hours or less, increased from 30.9% in 2010 to 35.6% in 2018.” Meanwhile, 45 percent of healthcare workers “reported not getting seven hours a night. For many, the norm was six or even just five hours.” https://www.npr.org/sections/health-shots/2019/10/28/773622789/working-americans-are-getting-less-sleep-especially-those-who-save-our-lives

Sunlight Exposure Is Reflected in Your Poop

the Sun can indeed shine out of your backside, suggests research. Not because you’re self-absorbed, but because you’ve absorbed gut-altering UV radiation. This is the first study to show that skin exposure to UVB light alters the gut microbiome in humans. Published in Frontiers in Microbiology, the analysis suggests that vitamin D mediates the change – which could help explain the protective effect of UVB light in inflammatory diseases like MS and IBD. Ratifying rodent studies Sun exposure, vitamin D levels and the mix of bacteria in our gut are each associated with risk of inflammatory conditions like MS and IBD. Scientists hypothesize that a causal chain links the three. Exposure to UVB in sunlight is well-known to drive vitamin D production in the skin, and recent studies suggest that vitamin D alters the human gut microbiome. However, that UVB therefore causes gut microbiome changes, via vitamin D production, has so far been shown only in rodents. https://www.technologynetworks.com/tn/news/sunlight-exposure-is-reflected-in-your-poop-326420?utm_campaign=NEWSLETTER_TN_Breaking%20Science%20News&utm_source=hs_email&utm_medium=email&utm_content=78538930&_hsenc=p2ANqtz-9xKZWZkOcvC61rINGuGspIVR4Q_pCP-hyBf_KZezZx66RDOOA-_a14ZOZyj3YgBeLaAXPyNwbAUfdpQdTAm8tBW8Q2vQ&_hsmi=78538930

Creatine Fuels T Cells’ Fight Against Cancer

Creatine, the organic acid that is popularly taken as a supplement by athletes and bodybuilders, serves as a molecular battery for immune cells by storing and distributing energy to power their fight against cancer, according to new UCLA research. The study, conducted in mice and published in the Journal of Experimental Medicine, is the first to show that creatine uptake is critical to the anti-tumor activities of CD8 T cells, also known as killer T cells, the foot soldiers of the immune system. The researchers also found that creatine supplementation can improve the efficacy of existing immunotherapies. “Because oral creatine supplements have been broadly utilized by bodybuilders and athletes for the past three decades, existing data suggest they are likely safe when taken at appropriate doses,” said Lili Yang, a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA and the study’s senior author. “This could provide a clear and expedient path forward for the use of creatine supplementation to enhance existing cancer immunotherapies.” https://www.technologynetworks.com/cancer-research/news/creatine-fuels-t-cells-fight-against-cancer-326197?utm_campaign=NEWSLETTER_TN_Breaking%20Science%20News&utm_source=hs_email&utm_medium=email&utm_content=78310030&_hsenc=p2ANqtz-9ROP3PYOUFRqcnAAr0Ao8sz7LvNNVmshJSiPmtNzYtqgeqnQnzqJ6P-YzgpyFniC5l4EbKHCPv5u_3Y_PDL98VUkEZuQ&_hsmi=78310030

Harmful Bacteria Combated by Breast Milk Compound

Researchers at National Jewish Health and the University of Iowa have identified a compound in human breast milk that fights infections by harmful bacteria while allowing beneficial bacteria to thrive. Human breast milk has more than 200 times the amount of glycerol monolaurate (GML) than is found in cows’ milk. Infant formula has none. GML is inexpensive to manufacture. Future research will determine if GML could be a beneficial additive to cow’s milk and infant formula. “Our findings demonstrate that high levels of GML are unique to human breast milk and strongly inhibit growth of pathogenic bacteria,” said Donald Leung, MD, PhD, professor of pediatrics at National Jewish Health and senior author on a paper in Scientific Reports. ‘While antibiotics can fight bacterial infections in infants, they kill the beneficial bacteria along with the pathogenic ones,” said Patrick Schlievert, PhD, professor of microbiology and immunology at the University of Iowa Carver College of Medicine and first author on the Scientific Reports paper. “GML is much more selective, fighting only the pathogenic bacteria while allowing beneficial species to thrive. We think GML holds great promise as a potential additive to cows’ milk and infant formula that could promote the health of babies around the world.” https://www.technologynetworks.com/applied-sciences/news/harmful-bacteria-combated-by-breast-milk-compound-325053?utm_campaign=NEWSLETTER_TN_Breaking%20Science%20News&utm_source=hs_email&utm_medium=email&utm_content=77954506&_hsenc=p2ANqtz-9pZ5xEXFwja4QNXh3jlbckIn3DKNHJsg9ypPnFUFZafawroqXDsw9IFejg9xP4giWco_YHR2mspLTm-qZ0B1BP6rVlVw&_hsmi=77954506

Drug Abstinence Changes Gene Expression, Making Relapse More Likely

prolonged abstinence “The novelty of our current paper is that it begins to reveal what happens on a cellular basis, what genes are turned on and off during a prolonged period of abstinence,” said David M. Dietz, PhD, senior author and chair of the Department of Pharmacology and Toxicology. The research focused on the nucleus accumbens, a center of reward and motivation in the brain. The researchers looked specifically at molecules known as chromatin remodelers that can facilitate or prevent access to DNA, ultimately affecting gene expression. They found that chromatin remodeler INO80 causes changes in gene expression that enhances cocaine-craving behavior. While after one day of abstinence from cocaine there was no change in expression of INO80, there was a significant increase after 30 days of abstinence. The findings also reveal how a class of proteins called E3 ubiquitin ligases facilitates relapse. Currently the subject of well-funded research in the pharmaceutical industry for psychiatric and neurologic diseases, E3 ubiquitin ligase proteins have yet to be well-explored in terms of their relevance to addiction and relapse. Last year, Werner and his colleagues at UB published the first paper regarding another one of these proteins and its role in addiction and relapse. The current UB study reveals that an E3 ubiquitin ligase called TRIM3 tags INO80 with a ubiquitin chain indicating to the cell to degrade INO80. The researchers found that a decrease in TRIM3 likely underlies the observed increase in INO80 (less TRIM3 means less INO80 being degraded). Increased drug craving “When there’s less TRIM3 and more INO80, that leads to an increase in drug craving,” said Werner, “but when there’s more TRIM3 and less INO80, drug-craving behavior is reduced.” They found this effect whether they manipulated INO80 directly, or through the alterations of TRIM3 levels, he said. “INO80 affects some combination of target genes,” said Werner. “In the future, we want to find out which of those downstream genes are contributing to drug-craving behaviors. This would be a big first step into this really new territory of how gene expression maintains relapse https://www.technologynetworks.com/genomics/news/drug-abstinence-changes-gene-expression-making-relapse-more-likely-325007?utm_campaign=NEWSLETTER_TN_Breaking%20Science%20News&utm_source=hs_email&utm_medium=email&utm_content=77906125&_hsenc=p2ANqtz-_45dRrGuKf0380b4bbq5aK1MhmjqD0QXrjFYGaN2sAX32wtw4I2YLiX29AuE8kyRpECmoz8HWvFGdxR9WEt0PzMrJm-A&_hsmi=77906125

These gases can react with other chemicals commonly found in homes, such as limonene –– an orange- or lemon-scented compound added to many personal care products, cleaners and air fresheners. In addition, indoor lighting or sunshine through windows might split HOCl and Cl2 into a hydroxyl radical and a chlorine atom, which can react with other compounds to form air particles called secondary organic aerosols (SOAs). These pollutants have been linked to respiratory problems and other adverse health effects. Chen Wang and colleagues wanted to see whether limonene and bleach fumes, at concentrations likely to occur in indoor environments, could react to produce SOAs under light and dark conditions.

Serum Interferon Predicts Lupus Flares High levels of interferon-alpha linked with fourfold greater risk of flare within a year

The persistent presence of interferon-α may not merely be a marker of disease activity during apparent remission, but also may play a pathologic role in the disease. "Interferon-α overexpression could be an explanation of chronic fatigue, depression, and reduction of sleep secondary to the stimulation of the dopamine metabolism by interferon-α in the central neurological system," the authors suggested. Interferon-α also may participate in some of the processes linked with the accelerated atherosclerosis seen in SLE, such as endothelial cell damage.

Culprit for Age-related Decline in Muscle Healing Uncovered

An age-related decline in recovery from muscle injury can be traced to a protein that suppresses the special ability of muscle stem cells to build new muscles, according to work from a team of current and former Carnegie biologists led by Chen-Ming Fan and published in Nature Metabolism. Skeletal muscles have a tremendous capacity to make new muscles from special muscle stem cells. These "blank" cells are not only good at making muscles but also at generating more of themselves, a process called self-renewal. But their amazing abilities diminish with age, resulting in poorer muscle regeneration from muscle trauma. The research team--including Carnegie's Liangji Li, Michelle Rozo, Sibiao Yue, Xiaobin Zheng, and Frederick Tan, as well as Christoph Lepper formerly of Carnegie now at the Ohio State University--figured out that a protein called GAS1 is the culprit for this age-related decline. "Encoded by the growth-arrest specific gene, the GAS1 protein lives up to its name, accelerating the functional decline of muscle stem cells," explained lead author Li. The protein is found in only a small number of young muscle stem cells, but is present in all aged muscle stem cells, they discovered. Tinkering with muscle stem cells to express GAS1 in the https://www.technologynetworks.com/drug-discovery/news/culprit-for-age-related-decline-in-muscle-healing-uncovered-324512?utm_campaign=NEWSLETTER_TN_Breaking%20Science%20News&utm_source=hs_email&utm_medium=email&utm_content=77506203&_hsenc=p2ANqtz--rjolzNTyeSIZQO2DzyIpYOqAzldhTtZVEgxSj93ElClROuOL0LoQwrtfOi0bgPDFG12U088ztoP6mPDo04WdjeQDJrQ&_hsmi=77506203
