Personalized cancer vaccines based on resected tumors from patients is promising to address tumor heterogeneity to inhibit tumor recurrence or metastasis. However, it remains challenge to elicit immune activation due to the weak immunogenicity of autologous tumor antigens. Here, a hybrid membrane cancer vaccine is successfully constructed by membrane fusion to enhance adaptive immune response and amplify personalized immunotherapy, which formed a codelivery system for autologous tumor antigens and immune adjuvants.

To address this issue, a facile and nanosized oxygen (O) bubble template is established by mixing oxygenated water and water-soluble solvents for guiding hollow polydopamine (HPDA) synthesis, and O is encapsulated in the cavity of HPDA. HPDA with abundant catechol is designed as a carrier for zinc phthalocyanine (ZnPc, a boronic acid modified photosensitizer) borate ester bonds to fabricate nanomedicine (denoted as HZNPs).

Regulating the expression and activity of parkin can remedy mitophagy and human disease. We developed an efficient method to isolate natural parkin ligands from herbal medicines by combining centrifugal ultrafiltration and liquid chromatography/mass spectrometry.

The polysaccharide fraction of can reduce insulin resistance and restore the gut microbiota in a rat model of aberrant lipid metabolism by down regulating miR-122. The aim of this study was to further elucidate the effect of on lipid metabolism, and the roles of specific miRNAs and the gut microbiota.

Mitophagy plays an important role in maintaining mitochondrial quality and cell homeostasis through the degradation of damaged, aged, and dysfunctional mitochondria and misfolded proteins. Many human diseases, particularly neurodegenerative diseases, are related to disorders of mitochondrial phagocytosis. Exploring the regulatory mechanisms of mitophagy is of great significance for revealing the molecular mechanisms underlying the related diseases.

Jiuzhuan Huangjing Pills (JHP) have been used for the treatment of human disease for over a thousand years, but their efficacy and underlying mechanism(s) of action against MAFLD are unknown. We investigated the alleviating effects of JHP on high-fat diet (HFD)-induced MAFLD.

Mitochondria are the 'engine' of cells. Mitochondrial dysfunction is an important mechanism in many human diseases. Many natural products could remedy the mitochondria to alleviate mitochondria-involved diseases.
View Article and Find Full Text PDFLong-term muscle fatigue is a major cause of injury. Drugs/nutrients from herbal medicines that prevent fatigue remain a major research focus. In China, a prescription composed of Polygonati Rhizoma and Notoginseng Radix et Rhizoma has been commonly used as a herb and food nutrient, providing protection against fatigue in the clinic.

Targeting the mitochondria to protect liver function has gained momentum due to their central role in energy production, apoptotic cell death, oxidative stress, calcium homeostasis, and lipid metabolism. In this study, we employed a hepatic mitochondria-based centrifugal ultrafiltration/liquid chromatography/mass spectrometry method (CM-HMC) to identify hepatic mitochondria ligands from medicinal herbs (MHs) including Notopterygii Rhizoma et Radix (NRR) that possess hepatic-protective effects.
View Article and Find Full Text PDFTargeting mitochondria as a hepatic-protective strategy has gained attention, because of their important roles in energy production, adjustment of apoptosis, and generation of reactive oxygen species. To promote the discovery of natural mitochondria-targeted hepatic-protectants, we established a hepatocellular mitochondria-based capturing method by coupling affinity ultrafiltration with liquid chromatography/mass spectrometry (LC/MS), which is suitable for identifying mitochondrial ligands from medicinal herbs (MHs). After evaluating the feasibility of the method, it was applied for capturing mitochondria-targeting constituents from Peucedani Radix extract.

Aim: To identify the effects and mechanism of action of () on dyslipidemia in rats using an integrated untargeted metabolomic method.
Methods: A rat model of dyslipidemia was induced with a high-fat diet (HFD) and rats were given [4 g/(kg•d)] intragastrically for 14 wk. Changes in serum and hepatic lipid parameters were evaluated.
