ABSTRACT
Ferroptosis is a novel type of cell death, which is distinguished from the traditional cell death pathways such as apoptosis, proptosis, necrosis and autophagy in terms of morphology, biochemistry and genetics. The main features of ferroptosis are the iron accumulation and lipid peroxidation. The regulation mechanism of ferroptosis involves glutathione metabolism, lipid peroxidation reactions and iron metabolism, which are closely related to the pathological process of tumor, aging, neurodegenerative diseases, ischemia reperfusion injury, cardiovascular and cerebrovascular diseases, kidney injury, hepatic fibrosis and so on. How to effectively study the role of ferroptosis regulation mechanism in the treatment of diseases becomes the hot spot and focus of the ferroptosis research. In recent years, with the in-depth study of ferroptosis, the identification, confirmation and the mechanism of ferroptosis have been developed significantly and have come forth continuously, in the meantime, techniques based on the morphology, biochemistry, molecular biology and genetics have been widely applied in the detection of ferroptosis. In order to deepen readers' understanding of ferroptosis and its detection methods, this paper will mainly review the current research progress on the detection methods and their application in ferroptosis, summarize and discuss their advantages and disadvantages in the detection of ferroptosis, this knowledge are crucial for better understanding and studying the biological function of ferroptosis.
ABSTRACT
Autophagy is a widespread and unique degradation process in eukaryotic cells. When cells are under various stress conditions such as nutritional deficiencies, growth factor deficiencies or hypoxia, autophagy will be initiated to maintain the stability of the internal environment and ensure normal proliferation and differentiation. At present, research on autophagy-related targets is mostly focused on tumor cells. In contrast, research on fungal autophagy targets is still limited. Autophagy plays an important role in growth, development and morphological changes of fungal cells, suggesting that research on fungal autophagy as a drug target should be useful. This article reviews the signal regulation and detection strategies for autophagy in fungal cells, and provides a research basis for the screening of antifungal drugs targeting autophagy-related proteins.
ABSTRACT
To modernize traditional Chinese medicine, its pharmacodynamic substances should be elucidated firstly. Modern chromatographic technologies play an important role in the clarification of the pharmacodynamic substances of Chinese medicine. In this paper, the advancement and application of current chromatographic techniques in the pharmacodynamic substances of Chinese medicines were reviewed from the aspects of detection, preparation and screening methods.
