Colorectal cancer (CRC) is stratified into four consensus molecular subtypes (CMS1-4). CMS3 represents the metabolic subtype, but its wiring remains largely undefined. To identify the underlying tumorigenesis of CMS3, organoids derived from 16 genetically engineered mouse models are analyzed.

Azospirillum argentinense Az19 is an osmotolerant plant growth-promoting bacterium that protects maize plants from drought. In this work, we explored the role of trehalose in the superior performance of Az19 under stress. The trehalase-coding gene treF was constitutively expressed in Az19 through a miniTn7 system.

In mammals, intestinal α-glucosidase exists as a maltase-glucoamylase complex (MGAM) and a sucrase-isomaltase complex (SI). In this study, we transiently expressed human MGAM and SI in human embryonic kidney 293 (HEK293) cells. At pH 6.

Background: With the global increase in metabolic disorders, identifying effective dietary strategies is crucial for enhancing health outcomes. While various health advantages of alkaline reduced water (ARW) have been documented, its specific impacts on glucose and lipid metabolism in both healthy and diabetic conditions are still not well understood.
Methods: This study investigates how ARW affects carbohydrate and lipid metabolism in male Wistar rats, which were induced to develop glucose metabolism disorders through subcutaneous injections of nicotinamide and streptozotocin (STZ).
Odd-Numbered Agaro-Oligosaccharides Produced by α-Neoagaro-Oligosaccharide Hydrolase Exert Antioxidant Activity in Human Dermal Fibroblasts.

Agarases produce agar oligosaccharides with various structures exhibiting diverse physiological activities. α-Neoagaro-oligosaccharide hydrolase (α-NAOSH) specifically cleaves even-numbered neoagaro-oligosaccharides, producing 3,6-anhydro-l-galactose (l-AHG) and odd-numbered agaro-oligosaccharides (OAOSs). In this study, α-NAOSH from the agar-degrading marine bacterium JEA5 (Gaa117) was purified and characterized using an expression system to produce OAOSs and determine their bioactivity.
