This study aimed to investigate the protective effects of ginsenoside Rg1 on high-altitude hypoxia-induced acute lung injury (ALI) and elucidated its molecular targets and related pathways, specifically its association with the fluid shear stress pathway. Using a combination of bioinformatics analysis and both in vivo and in vitro experiments, we assessed the role of ginsenoside Rg1 in mitigating physiological and biochemical disturbances induced by hypoxia. In the in vivo experiments, we measured arterial blood gas parameters, levels of inflammatory cells and cytokines, erythrocyte and platelet parameters, and conducted histological analysis in rats.

Fasting as an Adjuvant Therapy for Cancer: Mechanism of Action and Clinical Practice.

Biomolecules

November 2024

Guangdong Provincial Key Laboratory for Research and Evaluation of Pharmaceutical Preparations, Department of Biotechnology, School of Life Sciences and Biopharmaceutics, Guangdong Pharmaceutical University, Guangzhou 510006, China.

The fundamental biological characteristics of tumor cells are characterized by irregularities in signaling and metabolic pathways, which are evident through increased glucose uptake, altered mitochondrial function, and the ability to evade growth signals. Interventions such as fasting or fasting-mimicking diets represent a promising strategy that can elicit distinct responses in normal cells compared to tumor cells. These dietary strategies can alter the circulating levels of various hormones and metabolites, including blood glucose, insulin, glucagon, growth hormone, insulin-like growth factor, glucocorticoids, and epinephrine, thereby potentially exerting an anticancer effect.

Probing antimicrobial synergy by novel lipopeptides paired with antibiotics.

J Colloid Interface Sci

March 2025

Biological Physics Laboratory, Department of Physics and Astronomy, School of Natural Science, The University of Manchester, Oxford Road, Manchester M13 9PL UK. Electronic address:

Antimicrobial resistance (AMR) is fast becoming a major global challenge in both hospital and community settings as many current antibiotics and treatment processes are under the threat of being rendered less effective or ineffective. Synergistic combination of an antibiotic and an aiding agent with a different set of properties provides an important but largely unexploited option to 'repurpose' existing biomaterial's space while addressing issues of potency, spectrum, toxicity and resistance in early stages of antimicrobial drug discovery. This work explores how to combine tetracycline/minocycline (TC/MC) with a broad-spectrum antimicrobial lipopeptide that has been designed to improve the efficiency of membrane targeting and intramembrane accumulation, thereby enhancing antimicrobial efficacy.

ACVR1 mediates renal tubular EMT in kidney fibrosis via AKT activation.

Cell Signal

January 2025

School of Basic Medical Sciences, Guangdong Pharmaceutical University, Guangzhou 510006, Guangdong, PR China. Electronic address:

Tubulointerstitial fibrosis in the kidneys is a chronic and progressive process. Although studies suggested that tubular epithelial-mesenchymal transition (EMT) plays a key role in the development of kidney fibrosis, whether ACVR1, a member of the TGFβ superfamily, is involved in the EMT needs to be illustrated. Using bioinformatics analysis of bulk-seq data (GSE23338 and GSE168876), we found that TGF-β1 perhaps activated the PI3K/AKT signaling pathway and induced the mRNA expression of ACVR1, fibronectin, and Collagen I in HK-2 cells (human renal tubular epithelial cell line).
