Abstract
Varicellovirus bovinealpha 1 (BoAHV-1) is a significant pathogen responsible for respiratory disease in cattle, capable of inducing lung damage independently or co-infection with bacteria. The widespread spread of BoAHV-1 in cattle herds has caused substantial economic losses to the cattle industry. The pathogenic mechanisms of BoAHV-1 are often relevant to robust inflammatory responses, increased oxidative burden, and the initiation of apoptosis. Glycyrrhizin (GLY) is a small-molecule triterpenoid saponin compound obtained from the herb liquorice, which has a broad spectrum of pharmacological properties such as antiviral, anti-inflammatory, and antioxidant effects. Furthermore, GLY regulates lung physiology by modulating oxidative stress, inflammatory response, and cell apoptosis through interference with the NF-κB/NLRP3 and Nrf2/HO-1 Signaling pathways. However, the potential of GLY to mitigate lung injury induced by BoAHV-1 and its underlying mechanism remains unclear. Therefore, in this study, we investigated the protective effect of GLY against pulmonary injury induced by BoAHV-1 in a guinea pig model by reducing viral load and suppressing the inflammatory response, oxidative stress, and apoptosis. The results of this study demonstrated that GLY exerted a protective effect against BoAHV-1-induced lung injury in guinea pigs. Specifically, GLY reduced the levels of pro-inflammatory cytokines interleukin (IL)-1β, tumor necrosis factor (TNF)-α, and interleukin (IL)-8 in guinea pig tissues while suppressing the expression of Caspase-1. Additionally, GLY reduced BoAHV-1 load and the number of TUNEL-positive lung cells in guinea pig lungs while inhibiting Caspase 3 protein expression. Furthermore, GLY significantly enhanced lung antioxidant capacity by increasing superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activity while simultaneously reducing malondialdehyde (MDA) levels. Lung histological observation and score further validated the protective effect of GLY on BoAHV-1-induced lung injury. Furthermore, we observed that the expression of phosphorylated NF-κB p65 (p-NF-κB p65) and NLRP3 proteins in the lung tissue of BoAHV-1-infected guinea pigs decreased after GLY treatment while the expression of Nrf2 and HO-1 proteins increased. These results indicated that GLY inhibited the NF-κB/NLRP3 Signaling pathway and activated the Nrf2/HO-1 Signaling pathway during BoAHV-1 infection. Ultimately, our findings demonstrated that GLY alleviates BoAHV-1-induced inflammation response, oxidative stress, and cell apoptosis by inhibiting the NF-κB/NLRP3 Signaling pathway and activating the Nrf2/HO-1 Signaling pathway to protect guinea pigs from lung injury caused by BoAHV-1. Ultimately, our findings demonstrated that GLY alleviates BoAHV-1-induced inflammation response, oxidative stress, and cell apoptosis by inhibiting the NF-κB/NLRP3 Signaling pathway and activating the Nrf2/HO-1 Signaling pathway to protect guinea pigs from lung injury caused by BoAHV-1. Importantly, this study provides a compelling argument for the GLY in combating respiratory disease in cattle caused by BoAHV-1.

Abstract
OBJECTIVE To investigate the protective effect of 5-hydroxy-6,7-dimethoxyflavone (5-HDF), a compound extracted from Elsholtzia blanda Benth., against lung injury induced by H1N1 influenza virus and explore its possible mechanism of action. METHODS 5-HDF was extracted from Elsholtzia blanda Benth. using ethanol reflux extraction and silica gel chromatography and characterized using NMR and MS analyses. In an A549 cell model of H1N1 influenza virus infection (MOI=0.1), the cytotoxicity of 5-HDF was assessed using MTT assay, and its effect on TRAIL and IL-8 expressions was examined using flow cytometry; Western blotting was used to detect the expression levels of inflammatory, apoptosis, and ferroptosis-related proteins. In a mouse model of H1N1 influenza virus infection established by nasal instillation of 50 μL H1N1 virus at the median lethal dose, the effects of 30 and 60 mg/kg 5-HDF by gavage on body weight, lung index, gross lung anatomy and lung histopathology were observed. RESULTS 5-HDF exhibited no significant cytotoxicity in A549 cells within the concentration range of 0-200 μg/mL. In H1N1-infected A549 cells, treatment with 5-HDF effectively inhibited the activation of phospho-p38 MAPK and phospho-NF-κB p65, lowered the expressions of IL-8, enhanced the expression of anti-ferroptosis proteins (SLC7A11 and GPX4), and inhibited the expressions of apoptosis markers PARP and caspase-3 and the apoptotic factor TRAIL. In H1N1-infected mice, treatment with 5-HDF for 7 days significantly suppressed body weight loss and increment of lung index and obviously alleviated lung tissue pathologies. CONCLUSION 5-HDF offers protection against H1N1 influenza virus infection in mice possibly by suppressing H1N1-induced ferroptosis, inflammatory responses, and apoptosis via upregulating SLC7A11 and GPX4, inhibiting the activation of phospho-NF-κB p65 and phospho-p38 MAPK, and decreasing the expression of cleaved caspase3 and cleaved PARP.

Abstract
Lung cancer stands as one of the most prevalent malignancies worldwide, bearing the highest morbidity and mortality rates among all malignant tumors. The treatment of lung cancer primarily encompasses surgical procedures, radiotherapy, and chemotherapy, which are fraught with significant side effects, unfavorable prognoses, and a heightened risk of metastasis and relapse. Although targeted therapy and immunotherapy have gradually gained prominence in lung cancer treatment, diversifying the array of available methods, the overall recovery and survival rates for lung cancer patients remain suboptimal. Presently, with a holistic approach and a focus on syndrome differentiation and treatment, Traditional Chinese Medicine (TCM) has emerged as a pivotal player in the prognosis of cancer patients. TCM possesses characteristics such as targeting multiple aspects, addressing a wide range of concerns, and minimizing toxic side effects. Research demonstrates that Traditional Chinese Medicine can significantly contribute to the treatment or serve as an adjunct to chemotherapy for lung cancer and other lung-related diseases. This is achieved through mechanisms like inhibiting tumor cell proliferation, inducing tumor cell apoptosis, suppressing tumor angiogenesis, influencing the cellular microenvironment, regulating immune system function, impacting signal transduction pathways, and reversing multidrug resistance in tumor cells. In this article, we offer an overview of the advancements in research concerning Traditional Chinese Medicine extracts for the treatment or adjunctive chemotherapy of lung cancer and other lung-related conditions. Furthermore, we delve into the challenges that Traditional Chinese Medicine extracts face in lung cancer treatment, laying the foundation for the development of diagnostic, prognostic, and therapeutic targets.

Int J Mol Sci 2023; 24:15263. [PMID: 37894943 PMCID: PMC10607353 DOI: 10.3390/ijms242015263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 10/12/2023] [Accepted: 10/16/2023] [Indexed: 10/29/2023] Open
Abstract
The Elsholtzieae, comprising ca. 7 genera and 70 species, is a small tribe of Lamiaceae (mint family). Members of Elsholtzieae are of high medicinal, aromatic, culinary, and ornamentals value. Despite the rich diversity and value of Elsholtzieae, few molecular markers or plastomes are available for phylogenetics. In the present study, we employed high-throughput sequencing to assemble two Mosla plastomes, M. dianthera and M. scabra, for the first time, and compared with other plastomes of Elsholtzieae. The plastomes of Elsholtzieae exhibited a quadripartite structure, ranging in size from 148,288 bp to 152,602 bp. Excepting the absence of the pseudogene rps19 in Elsholtzia densa, the exhaustive tally revealed the presence of 132 genes (113 unique genes). Among these, 85 protein-coding genes (CDS), 37 tRNA genes, 8 rRNA genes, and 2 pseudogenes (rps19 and ycf1) were annotated. Comparative analyses showed that the plastomes of these species have minor variations at the gene level. Notably, the E. eriostchya plastid genome exhibited increased GC content regions in the LSC and SSC, resulting in an increased overall GC content of the entire plastid genome. The E. densa plastid genome displayed modified boundaries due to inverted repeat (IR) contraction. The sequences of CDS and intergenic regions (IGS) with elevated variability were identified as potential molecular markers for taxonomic inquiries within Elsholtzieae. Phylogenetic analysis indicated that four genera formed monophyletic entities, with Mosla and Perilla forming a sister clade. This clade was, in turn, sister to Collinsonia, collectively forming a sister group to Elsholtzia. Both CDS, and CDS + IGS could construct a phylogenetic tree with stronger support. These findings facilitate species identification and DNA barcoding investigations in Elsholtzieae and provide a foundation for further exploration and resource utilization within this tribe.

Abstract
The lower respiratory tract infection, induced by influenza virus, coronaviruses, and respiratory syncytial virus, remains a serious threat to human health that can cause a global pandemic. Thus, finding effective chemicals and therapeutic measures to advance the functional restoration of the respiratory tract after infection has been the emphasis of the studies on the subjects. Mosla scabra is a natural medicinal plant used for treating various lung and gastrointestinal diseases, including viral infection, cough, chronic obstructive pulmonary disease, acute gastroenteritis, and diarrhoea. In this study, the antiviral and anti-inflammatory effects of total lignans (MSTL) extracted from the plant were investigated in influenza A virus (IAV)-infected mice and RAW 264.7 macrophages. MSTL could not only protect the macrophages against IAV-induced pyroptosis but also could lighten the lung inflammation induced by IAV in vivo and in vitro. The network pharmacology analysis revealed that differentially expressed genes, mainly involving in EGFR tyrosine kinase inhibitor resistance, endocrine resistance, HIF-1 signaling pathway, C-type lectin receptor signaling pathway, and FOXO signaling pathway, contributed to the IAV-induced alveolar macrophage dysfunction. It indicated that MSTL enhanced the function of alveolar macrophages and improved IAV-induced lung injury in mice.
