Imaging NRF2 activation in non-small cell lung cancer with positron emission tomography.

Mutations in the NRF2-KEAP1 pathway are common in non-small cell lung cancer (NSCLC) and confer broad-spectrum therapeutic resistance, leading to poor outcomes. Currently, there is no means to non-invasively identify NRF2 activation in living subjects. Here, we show that positron emission tomography imaging with the system x radiotracer, [F]FSPG, provides a sensitive and specific marker of NRF2 activation in orthotopic, patient-derived, and genetically engineered mouse models of NSCLC.

sp. nov., a member of the isolated from badland surfaces in the Red Desert, Wyoming, USA.

A novel Gram-stain-positive, black-pigmented bacterium, designated as WL48A , was isolated from the surface of badland sedimentary rock in the Red Desert of Wyoming and characterized using a polyphasic taxonomic approach. Good growth occurred at 28-32 °C, pH 7-9, and NaCl less than 1% (w/v). Colonies, growing well on International Streptomyces Project media (ISP) 3 and ISP 7, were black and adhering to the agar.

Neuromodulation on the ground and in the clouds: a mini review of transcranial direct current stimulation for altering performance in interactive driving and flight simulators.

Transcranial direct current stimulation (tDCS) has emerged as a promising tool for cognitive enhancement, especially within simulated virtual environments that provide realistic yet controlled methods for studying human behavior. This mini review synthesizes current research on the application of tDCS to improve performance in interactive driving and flight simulators. The existing literature indicates that tDCS can enhance acute performance for specific tasks, such as maintaining a safe distance from another car or executing a successful plane landing.

Inhibition of miR-4763-3p expression activates the PI3K/mTOR/Bcl2 autophagy signaling pathway to ameliorate cognitive decline.

Cognitive decline and memory impairment are subsequently result in neuronal apoptosis and synaptic damage. Aberrant regulation of microRNAs has been implicated in the pathogenesis of Alzheimer's disease (AD) and may play a pivotal role in the early stages of the disease. In this study, we identified the critical role of miR-4763-3p in AD pathogenesis, focusing on early-stage mild cognitive impairment (AD-MCI).

The structure of an amyloid precursor protein/talin complex indicates a mechanical basis of Alzheimer's disease.

Misprocessing of amyloid precursor protein (APP) is one of the major causes of Alzheimer's disease. APP comprises a large extracellular region, a single transmembrane helix and a short cytoplasmic tail containing an NPxY motif (normally referred to as the YENPTY motif). Talins are synaptic scaffold proteins that connect the cytoskeletal machinery to the plasma membrane via binding NPxY motifs in the cytoplasmic tail of integrins.
