New stem cell vesicles accelerate diabetic wound healing
Diabetic foot ulcers are among the most serious complications of diabetes because prolonged inflammation, poor circulation, and defective…
Rice University chemists develop cheaper way to synthesize drugs
Pharmaceutical drugs often rely on chemical compounds found in the body. Take phosphate, a common compound cells use…
Researchers uncover molecular switch controlling nutrient-driven cell growth
Cells carry their own growth switches. When enough nutrients-amino acids in particular-are available, cells flip this switch on…
Could vitamin D in midlife protect your brain from early Alzheimer’s?
A long-term study suggests that vitamin D levels in your 30s and 40s could influence early brain changes…
Blocking nitric oxide suppresses tumor growth in aggressive pediatric neuroblastoma
The tumor begins before birth. Somewhere in the developing fetus, neural crest cells that should have matured into…
Combined CDK4/6 and EGFR inhibition improves pancreatic cancer therapy
Clinically available KRAS inhibitors mainly target G12C, which is rare in PDAC and often acquires resistance. Oncogenic KRAS…
Study identifies PPP2R5C blood marker that may detect Alzheimer’s disease earlier
Researchers report that declining PPP2R5C levels in blood may signal early Alzheimer’s pathology, offering new insight into tau…
A shingles vaccine may delay dementia onset
A clever natural experiment in Canada suggests a routine shingles vaccine may do more than prevent rash. Instead,…
COVID-19 severity is linked to changes in mitochondrial DNA methylation
New evidence from Indian patients shows that severe COVID-19 is associated with distinct mitochondrial methylation signatures and altered…
Early exposure to fat-related food smells increases lifelong obesity risk
New experimental evidence shows that food smells encountered before birth and during early life can rewire brain and…
New method reveals how human cells initiate DNA replication
When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process…
Comprehensive kinase atlas reveals new insights into cell signaling and disease
The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme’s…
