Vitamin B2 keeps a key anti-ferroptosis enzyme stable, and a riboflavin mimic can switch it off in cancer cells
A CRISPR screen shows riboflavin stabilizes FSP1, a shield against ferroptosis. The riboflavin analog roseoflavin disables it and sensitizes cancer cells to ferroptosis.
Obesogenic diets and gut bacteria team up to boost cancer immunotherapy in mice
Across 12 mouse diet models, anti-PD-1 response varied with diet but showed no significant association with metabolic measures. Separately, L. johnsonii plus an obesogenic diet promoted tumor regression in germ-free mice.
Skin and gut bacteria may predict eczema before it starts and point to new microbiome therapies
A review of how skin and gut microbes drive atopic dermatitis, which early biomarkers predict it, and how probiotics and live bacterial transplants may help.
Higher Methyl-Donor Nutrient Intake Tracks With Lower Frailty Odds
In 13,528 U.S. adults, higher methyl-donor nutrient scores tracked with lower frailty odds. Oxidative stress may help explain the association.
Fermented Dairy Shows No Consistent Link to Better Muscle Function in Older Adults
Data from 6,790 adults in Ireland found no consistent link between fermented dairy intake and better strength or physical function.
UK Lupus Study Finds Unequal Responses After Treatment Escalation
Only 23% met major response criteria after stronger lupus treatment. Black patients had greater initial disease burden and lower observed response.
Study Links Long-Term Chlorpyrifos Exposure to Higher Parkinson’s Risk
A UCLA study links pesticide exposure to higher Parkinson’s risk, while lab experiments suggest how the chemical may damage brain cells.
Semaglutide and Tirzepatide Linked to Fewer Alcohol-Related Emergency Visits
Adults with type 2 diabetes taking semaglutide or tirzepatide had fewer alcohol-related emergency visits than those taking SGLT2 inhibitors.
Povorcitinib Improves Facial Pigmentation in Two Phase 3 Vitiligo Trials
A daily pill improved facial pigmentation in two yearlong vitiligo trials, but only about one in five patients reached the main treatment target.
Injectable Gel Helps a Repair Protein Rebuild Injured Muscle in Preclinical Study
A gel released Cripto for up to 28 days and improved muscle repair in a preclinical model, while a single protein injection did not.
Folic Acid Protects Muscle in Mice Exposed to Alcohol by Changing Gut Microbes
Folic acid improved muscle strength in mice exposed to alcohol, with gut microbes helping drive the benefits. Human studies are still needed.
Researchers Propose 10 Biological Hallmarks to Explain Facial Aging
A proposed framework links facial aging to 10 tissue processes, but studies must show whether it improves treatment decisions.
