What you eat before age 2 may affect your health 70 years later

2 weeks 4 days ago
Britain’s postwar sugar rationing created a rare natural experiment that let researchers examine how early sugar exposure might affect health decades later. People who experienced more rationing during their first 1,000 days had lower rates of several cancers and showed signs of slower biological aging. They were also still eating less sugar and maintaining healthier diets around age 50.

Turmeric compound may protect blood vessels from diabetes damage

2 weeks 4 days ago
A compound found in turmeric may help protect blood vessels from some of the damage caused by Type 1 diabetes. In rats, curcumin reduced inflammation, improved cellular signaling, and restored vascular health to levels resembling those of nondiabetic animals. The results hint at a possible new way to reduce the long-term cardiovascular risks of diabetes, but human trials are still needed.

Aberrant excitatory neuronal ERBB4 promotes Alzheimer's disease pathology

2 weeks 4 days ago
Neuroinflammation and synapse loss are associated with cognitive decline in Alzheimer's disease (AD). Although microglial hyperphagocytic activity has been implicated in synapse loss^(1-4), the mechanisms underlying these pathologies remain obscure. Here we demonstrate that, during AD progression in mice, astrocytes and microglia increase phagocytic elimination of excitatory synapses while reducing elimination of inhibitory synapses, suggesting that neuroinflammation alone may be dispensable for...

Next-generation multiplexed targeted proteomics quantifies post-translational modifications in disease and compound-protein interactions with high throughput

2 weeks 4 days ago
The GoDig platform enables sensitive, multiplexed targeted pathway proteomics without manual scheduling or synthetic standards. Here we present GoDig 2.0, which increases sample multiplexing to 35-fold, improves time efficiency and reduces scan delays for higher success rates, and allows flexible spectral and elution library generation from different mass spectrometry data types. GoDig 2.0 measures 2.4× more targets than GoDig 1.0, quantifying >99% of 800 peptides in a single run. We compile a...
