Shikonin ameliorated LPS-induced acute lung injury in mice via modulating MCU-mediated mitochondrial Ca and macrophage polarization.

Background: Macrophages play a pivotal role in the development and recovery of acute lung injury (ALI), wherein their phenotypic differentiation and metabolic programming are orchestrated by mitochondria. Specifically, the mitochondrial calcium uniporter (MCU) regulates mitochondrial Ca (Ca) uptake and may bridge the metabolic reprogramming and functional regulation of immune cells. However, the precise mechanism on macrophages remains elusive.

Yi Qi Chu Tan Formula (YQCTF) inhibited the progress of lung cancer via regulating tumor-associated neutrophil: An integrated study of network pharmacology, proteomics and pharmacodynamics.

Ethnopharmacological Relevance: Yi Qi Chu Tan Formula (YQCTF), a prescription consisting of eight traditional Chinese medicine for treating lung cancer, has been clinically proven to be effective in improving the life quality and prolonging the survival time of non-small cell lung cancer (NSCLC) patients.

Aim Of The Study: This study aimed to evaluate the therapeutic efficacy of YQCTF on NSCLC mice model and further explore its therapeutic targets by using network pharmacology, proteomics and pharmacodynamic methodologies.

Materials And Methods: The network pharmacology analysis was firstly conducted to screen out the potential active ingredients and therapeutic targets of YQCTF against NSCLC.

Shikonin ameliorated mice colitis by inhibiting dimerization and tetramerization of PKM2 in macrophages.

Dysregulated immune response plays a pivotal role in Ulcerative colitis. In lamina propria of inflammatory colonic mucosa, macrophages tend to polarize into M1 type and metabolically reprogram to aerobic glycolysis. PKM2 orchestrates glucose metabolic switch in macrophages, which tetramer has high pyruvate kinase activity, while which dimer mainly works as a protein kinase to stabilize HIF-1α and mediate anabolism.

Enantioseparation and determination of triazole fungicides in fruit juice by aqueous biphasic system coupled with HPLC-MS/MS.

The aqueous biphasic system based on choline ionic liquids and ethylene/propylene oxide copolymer coupled with high-performance liquid chromatography-tandem mass spectrometry was developed for the simultaneous determination of the enantiomers of two fungicides: myclobutanil and tebuconazole. The influence of mass fractions of ionic liquids and the copolymer on the extraction efficiency of the target fungicides was investigated. The analytes are mainly concentrated in the bottom, copolymer-rich phase.
