Poly-GA Links ERK1/2 Activation to Tau Pathology
2026-09-23
A cellular study links C9ORF72-associated poly-Glycine-Alanine to ERK1/2 interaction and hyperphosphorylation, accompanied by increased tau phosphorylation, aggregation, and cell death. Pharmacological blockade with U0126 attenuated these outcomes, identifying MEK–ERK signaling as a candidate mechanistic link that warrants testing beyond cellular models.

Prevotella copri, IPA, and Breast Cancer Progression
2026-09-21
The 2024 Gut Microbes study identifies Prevotella copri as a microbiome-associated driver of breast cancer progression and proposes depletion of host indole-3-pyruvic acid (IPA, also termed IPyA) as the metabolic link. Its experiments connect tryptophan consumption by P. copri with UHRF1-associated suppression of AMPK signaling, providing a mechanistic framework for microbiome–metabolite–tumor interactions and several testable workflows.
