Digging into the past: What ancient proteins say about real medieval meals

Researchers used stable isotope and proteomic analyses on medieval European skeletons to uncover the details of ancient diets. The findings revealed a heavy reliance on C3 plants, terrestrial animal proteins, legumes, and freshwater fish, demonstrating the power of combining methods for paleodietary reconstruction.

Probiotic strains have different effects on gut recovery after antibiotics

All probiotics are not created equal, according to new research from North Carolina State University. In a mouse model, researchers found that different probiotic strains can either accelerate or delay the gut microbiome's recovery after antibiotic treatment.

Goat milk boosts muscle health better than cow’s milk in animal study

Dairy products, especially low-fat and fortified goat milk, significantly improved muscle mass, reduced inflammation, and positively modulated gut microbiota in a mouse model of sarcopenia. These findings suggest tailored dairy interventions could help delay age-related muscle loss.

Blocking GAPDH aggregation protects brain cells and opens new path for stroke therapy

In a mouse model of acute ischemic stroke, researchers showed that inhibiting the aggregation of GAPDH, either genetically or with a novel peptide, significantly reduced brain damage and improved neurological function. The findings highlight GAPDH aggregation as a promising therapeutic target for stroke intervention.

Researchers turn a deadly fungus into potent cancer-fighting compound

Penn-led researchers have turned a deadly fungus into a potent cancer-fighting compound. After isolating a new class of molecules from Aspergillus flavus, a toxic crop fungus linked to deaths in the excavations of ancient tombs, the researchers modified the chemicals and tested them against leukemia cells.

Targeting ST6Gal-I shows promise in reducing Alzheimer’s disease pathology

A recent study published in Engineering has provided novel insights into the involvement of α2,6-sialylation in Alzheimer's disease (AD), revealing that the ablation of α2,6-sialyltransferase-I (ST6Gal-I), an enzyme responsible for α2,6-sialylation, can downregulate BACE1 expression and suppress the production of amyloid-β42 (Aβ42) plaques, which are hallmarks of AD.

Estrogen-responsive cells found to heighten gut pain in females

Researchers uncovered how estrogen heightens gut sensitivity in females by activating PYY-secreting L-cells, which stimulate serotonin release from EC cells. This paracrine circuit intensifies pain signaling and may explain the sex bias in conditions like IBS.

New computational tool uncovers hidden genetic mutations in proteins

Scientists at UCLA and the University of Toronto have developed an advanced computational tool, called moPepGen, that helps identify previously invisible genetic mutations in proteins, unlocking new possibilities in cancer research and beyond.

Short peptides show promise in blocking breast cancer metastasis

A surgeon can excise breast cancer from the body, but even the most skilled scalpel may not be able to remove every cell - especially when the cells have spread from the original disease site elsewhere in the body.

New large-scale study maps early triggers of Alzheimer’s protein aggregation

A new large-scale study has mapped the first molecular events that drive the formation of harmful amyloid protein aggregates found in Alzheimer's disease, pointing towards a new potential therapeutic target.

New family of antibiotics derived from the body's own proteins

A team of scientists led by the UAB has identified a new type of antimicrobial peptides (AMPs) found in human proteins that are capable of selectively eliminating multidrug-resistant bacteria, particularly of the gram-negative type, responsible for serious hospital acquired infections.
