Article Abstract
Licorice ( Fisch.), a medicinal and food homologous herb, contains licorice total flavonoids (LTF) as key bioactive components with unresolved hepatoprotective mechanisms. In this study, we focused on the mechanism by which LTF improved antioxidant capacity and regulated the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway according to network pharmacology. LTF upregulated the expression of Nrf2 and its downstream antioxidant-related factors, thereby enhancing the antioxidant capacity of the RAW264.7 cells. LTF alleviated liver injury in mice by activating the Nrf2 pathway and increased the abundance of , , and in the gut. We isolated a strain of () from mouse feces. Indeed, both and heat-inactivated alleviated liver injury in mice by activating the Nrf2 pathway. These results suggest that LTF and its upregulated synergistically activate the Nrf2 pathway to alleviate liver injury in mice.

Purpose: To explore the causal links between antihypertension drugs usage and age-related macular degeneration (AMD).
Methods: Multiple genetic analyses, including summary data-based Mendelian randomization (SMR), traditional MR, and colocalization analysis, were used to explore the causal associations between antihypertension drugs and AMD. Clinical data from the UK Biobank and the National Health and Nutrition Examination Survey (NHANES) was applied to refined risk assessment of specific antihypertensive medications in the context of AMD development.

Humans' exposure to arsenic (As) has been associated with the development of various diseases. Some health effects may be mediated by arsenic-induced toxicity to the thyroid and endocrine systems, but its underlying mechanisms remain unclear. The overall aim of our study was focused on using sodium arsenite (NaAsO)-exposed rats to investigate the involvement of the phosphatidylinositol 3-kinase (PI3K) and transcription factor NF-E2-related factor 2 (Nrf2) pathways in toxicity to the thyroid and endocrine systems.

Methicillin-resistant Staphylococcus aureus (MRSA) is a highly virulent and drug-resistant pathogen frequently causing bacterial pneumonia. Currently, there are limited effective treatments available due to the rapidly evolving resistance of bacteria. Therefore, there is an urgent need to develop novel therapies that focus on host-pathogen interactions.
