Cuproptosis exhibits enormous application prospects in treatment. However, cuproptosis-based therapy is impeded by the limited intracellular copper ions, the nonspecific delivery, uncontrollable release, and chelation of endogenous overproduced glutathione (GSH). In this work, an ultrasound-triggered nanosonosensitizer (p-TiO-Cu(I)) was constructed for Cu(I) delivery, on-demand release, GSH consumption, and deeper tissue response.

Glycosaminoglycans (GAGs) are essential bone extracellular matrix molecules that regulate osteoblast differentiation. Numerous studies have explored endogenous and exogenous GAG osteoanabolic activities using appropriate in vitro and in vivo models. However, GAGs' underlying the mechanism of action and structure-function relationships need to be elucidated in detail.

Optimizing central carbon metabolism (CCM) represents an attractive and challenging strategy to improve the biosynthesis of valuable chemicals due to the complex regulation of the CCM in yeast. In this study, we triggered the similar Warburg effect of cancer cells in yeast strains by introducing the human hypoxia-inducible factor-1 (HIF-1) complex, which regulated the expression of numerous enzymes involved in CCM and redirected the metabolic flux from glycolysis to tricarboxylic acid cycle. This redirection promoted the production of squalene to a 2.

A high-throughput sequencing identified 1283 lncRNAs in anthers at different stages in Arabidopsis and their relationship with protein-coding genes and miRNAs during anther and pollen development were analyzed. Long non-coding RNAs (lncRNAs) are important regulatory molecules involved in various biological processes. However, their roles in male reproductive development and interactions with miRNAs remained elusive.

Dopamine can play opposing physiological roles depending on the receptor subtype. In the fruit fly , and encode the D- and D-like receptors, respectively, and are reported to oppositely regulate intracellular cAMP levels. Here, we profiled the expression and subcellular localization of endogenous Dop1R1 and Dop2R in specific cell types in the mushroom body circuit.
