Multiplexed mosaic tumor models reveal natural phenotypic variations in drug response within and between populations.

Many agents that show promise in preclinical cancer models lack efficacy in patients due to patient heterogeneity that is not captured in traditional assays. To address this problem, we have developed GENEVA, a platform that measures the molecular and phenotypic consequences of drug perturbations within diverse populations of cancer cells at single-cell resolution, both and . Here, we apply GENEVA to study the KRAS G12C inhibitors, recapitulating known properties of these drugs and uncovering a previously unknown role for mitochondrial activation in cell death induced by KRAS inhibition.

Beyond the desert sands: decoding the relationship between camels, gut microbiota, and antibiotic resistance through metagenomics.

Background: Camels, known as the enduring "ships of the desert," host a complex gut microbiota that plays a crucial role in their survival in extreme environments. However, amidst the fascinating discoveries about the camel gut microbiota, concerns about antibiotic resistance have emerged as a significant global challenge affecting both human and animal populations. Indeed, the continued use of antibiotics in veterinary medicine has led to the widespread emergence of antibiotic-resistant bacteria, which has worsened through gene transfer.

Tools for regulating metabolic diseases: extracellular vesicles from adipose macrophages.

Metabolic diseases have gradually become one of the most significant global medical burdens. Diseases such as obesity, diabetes, and metabolic syndrome, along with their complications, are clinically categorized as metabolic diseases. Long-term oral medication significantly reduces patient compliance and quality of life.

Availability, price and nutritional assessment of plant-based meat alternatives in hypermarkets and supermarkets in Petaling, the most populated district in Malaysia.

This study investigated the availability, price, nutritional composition, and quality of plant-based meat alternatives (PBMAs) in supermarkets and hypermarkets in Petaling, the most populated district in Malaysia. The survey covered 85 stores through on-site visits, identifying 251 unique PBMA products from 42 brands. The PBMAs were categorized into nine groups: Burgers/Patties, Coated Meat, Luncheon Meat, Minced Meat, Pastries, Pieces/Chunks/Fillets/Strips, Prepacked Cooked Meals, Sausages, and Seafood Balls/Cakes/Meatballs.

Vimentin modulates regulatory T cell receptor-ligand interactions at distal pole complex, leading to dysregulated host response to viral pneumonia.

Forkhead box P3 (Foxp3) regulatory T cells (Tregs) resolve acute inflammation and repair the injured lung after viral pneumonia. Vimentin is a critical protein in the distal pole complex (DPC) of Tregs. This study reveals the inhibitory effect of vimentin on the suppressive and reparative capacity of Tregs.
