Study shows how prostate tumors rewire metabolism to resist therapy

Prostate tumors can rewire amino acid metabolism to override the normal brakes on cholesterol production, a process that may fuel hormone therapy resistance, according to a study by Weill Cornell Medicine investigators.

More coffee, higher testosterone? This study found a more complicated picture

Higher habitual coffee intake was associated with a leaner body composition, lower circulating branched-chain amino acids, and distinct cardiometabolic patterns in 2,264 middle-aged Finnish adults. Hormonal associations differed by sex, with broader testosterone- and SHBG-related patterns in men and more limited SHBG-related changes in women.

Restricting select amino acids may mimic protein restriction’s healthy aging benefits

A review finds that restricting protein, particularly methionine, isoleucine, and valine, may improve metabolism and influence key aging pathways, largely in experimental models. Short human studies suggest metabolic benefits, but effects on lifespan remain unknown and restriction may harm people with unmet or increased protein needs.

Consuming less protein could have greater health benefits and extend lifespan

Protein-fortified foods are popping up everywhere, from cereal and coffee to even protein water. But a new review covering over 350 papers on protein restriction and aging-publishing July 31 in the Cell Press journal Cell Press Blue-suggests that consuming less protein could have greater health benefits and could, in some cases, extend lifespan.

Eating habits directly influence vaginal microbiome, research finds

A cross-sectional study of young Italian women found that higher intake of animal protein and alcohol is associated with vaginal microbiota dysbiosis, while linolenic acid (a plant-based omega-3) and dietary fiber support beneficial Lactobacillus communities.

Gut microbiota and metabolic changes linked to pregnancy risks in women with PCOS

A new study presented today at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) reveals that women with polycystic ovary syndrome (PCOS) have distinct gut microbiota and metabolic signatures linked to premature endometrial aging and a higher risk of adverse pregnancy outcomes.

New biomarkers could help improve detection and treatment of gastrointestinal diseases

Scientists have discovered a range of 'biomarkers' that could help to improve detection and treatment of gastrointestinal diseases (GIDs) such as gastric cancer (GC), colorectal cancer (CRC), and inflammatory bowel disease (IBD).

How nutritious is dried Gapal? Study reveals its strengths and one hidden weakness

Researchers analyzed the nutritional composition of dried Gapal, a traditional fermented milk-cereal food from Burkina Faso, revealing its high carbohydrate and mineral content. Despite its nutritional potential, high phytic acid levels may limit mineral bioavailability, especially for zinc.

What blueberries do and don’t do for your microbiome and heart

Regular blueberry consumption for 12 weeks enriched Coriobacteriales incertae sedis in the gut microbiota of older overweight adults. However, this microbial shift was not linked to significant improvements in cardiometabolic biomarkers.

Human-specific gene variant may hold key to evolution of language

The origins of human language remain mysterious. Are we the only animals truly capable of complex speech? Are Homo sapiens the only hominids who could give detailed directions to a far-off freshwater source or describe the nuanced purples and reds of a dramatic sunset?

Could taking vinegar every day help reduce depression?

In a recent study, daily vinegar ingestion significantly improved depression scores in overweight, healthy adults over four weeks, potentially due to enhanced niacin metabolism.

Researchers engineer water-soluble histidine kinase for enhanced antibiotic drug screens

A bacterial enzyme called histidine kinase is a promising target for new classes of antibiotics. However, it has been difficult to develop drugs that target this enzyme, because it is a "hydrophobic" protein that loses its structure once removed from its normal location in the cell membrane.

New insights into coronavirus E channel could lead to antiviral drugs

The genome of the SARS-CoV-2 virus encodes 29 proteins, one of which is an ion channel called E. This channel, which transports protons and calcium ions, induces infected cells to launch an inflammatory response that damages tissues and contributes to the symptoms of Covid-19.
