When the Expected Scenario Did Not Occur: A Novel Mutation Resembling Neuromyelitis Optica Spectrum Disorder.

Mitochondrial complex I transfers electrons from NADH (nicotinamide adenine dinucleotide) to ubiquinone, facilitating ATP synthesis via a proton gradient. Complex I defects are common among the mitochondrial diseases, especially in childhood. , located in complex I's transmembrane domain, is not directly involved in catalytic activity, but the mutations are associated with Leigh syndrome and complex I defects.

TDO2 inhibition counters Benzo[a]pyrene-induced immune evasion and suppresses tumorigenesis in lung adenocarcinoma.

Introduction: Benzo[a]pyrene (BaP) is a toxic polycyclic aromatic hydrocarbon known as an exogenous AhR ligand. This study investigates the role of BaP in inducing immune checkpoint expression in lung adenocarcinoma (LUAD) and the underlying mechanisms involving the aryl hydrocarbon receptor (AhR) and tryptophan (Trp) metabolism.

Methods: We assessed the expression of immune checkpoint molecules, including PD-L1 and ICOSL, in lung epithelial cell lines (BEAS-2B and H1975) exposed to BaP.

Usnic Acid Targets 14-3-3 Proteins and Suppresses Cancer Progression by Blocking Substrate Interaction.

The anticancer therapeutic effects of usnic acid (UA), a lichen secondary metabolite, have been demonstrated and . However, the mechanism underlying the anticancer effect of UA remains to be clarified. In this study, the target protein of UA was identified using a UA-linker-Affi-Gel molecule, which showed that UA binds to the 14-3-3 protein.

Anithiactin D, a Phenylthiazole Natural Product from Mudflat-Derived sp., Suppresses Motility of Cancer Cells.

Anithiactin D (), a 2-phenylthiazole class of natural products, was isolated from marine mudflat-derived actinomycetes sp. 10A085. The chemical structure of was elucidated based on the interpretation of NMR and MS data.
