This article explores epithelial-to-mesenchymal transition (EMT) as a fundamental mechanism of cellular plasticity that enables cancer cells to adapt, survive, and spread.

A critical discovery is the role of the lanKC gene , which facilitates bacterioci...

This research identifies a sophisticated metabolic rewiring that occurs during the transition from naive to primed pluripotency in mouse embryos and stem cells. Rather than a simple reduction in mitochondrial activity, the studies reveal that pyruvate cycling and reductive glutamine metabolism are essential for maintaining developmental progression and cell-state transitions. Pyruvate acts as a ce...

These digital twins succ...

This study utilizes single-cell whole-genome sequencing to reveal that neurons in ALS, FTD, and Alzheimer’s disease exhibit significantly elevated levels of somatic mutations compared to healthy brains. Researchers identified a specific mutational signature primarily composed of 2-bp deletions , which serves as a unifying marker of genomic instability across these diverse neurodegenerative conditi...

This research identifies the lysosomal origins of the symbiosome , a specialized organelle that allows corals and sea anemones to host photosynthetic algae. By analyzing the proteome of this compartment in the anemone Aiptasia , scientists discovered that host animals co-opt existing cellular machinery typically used for digestion to instead support and maintain their symbionts. A critical finding...
