Integrated phytochemical and bioactivity profiling of Xanthium strumarium fruits from Korea and China: Implications for origin‐specific quality specification

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Geographic origin influences the phytochemical composition and biological activities of medicinal plant resources. Xanthium strumarium L. (XS) fruit is widely used in East Asian traditional medicine. However, current pharmacopeial standards primarily recognize Chinese‐derived material, despite the availability and traditional use of

STARD4 abundance regulates sterol transport and sensing

, 2011
Nonvesicular transport of cholesterol plays an essential role in the distribution and regulation of cholesterol within cells, but it has been difficult to identify the key intracellular cholesterol transporters. The steroidogenic acute regulatory-related

LKB1 Loss Sensitizes Lung Tumor Spheres to Mitomet‐Induced Ferroptosis, and These Effects are Enhanced by mTOR Inhibition

Molecular Carcinogenesis, EarlyView.
ABSTRACT Owing to their robust antioxidant defense mechanisms, cancer stem‐like cells (CSCs) maintain a low level of oxidative stress, which is crucial for preserving stemness and pluripotency. Therefore, agents that either directly generate reactive oxygen species (ROS) or inhibit the antioxidant defense systems can selectively induce oxidative cell ...
