This study aimed to investigate the activity and mechanism of Citri grandis Exocarpium-Cordyceps militaris on reliving cough by the use of network pharmacology. Mouse cough inducing models were constructed to evaluate the cough suppressant activity of the compound. Multiple online databases and literature searches were then used to collect the active ingredients, targets of action and disease targets of the compound. Construction of compound-target-disease networks and protein interaction networks using Cytoscape and STRING, and GO and KEGG enrichment analysis of target genes using Meatscape. The results showed that the low and high dose groups significantly reduced the number of coughs in mice (P<0.001) and decreased the levels of three inflammatory factors, tumor necrosis factor, interleukin 1α and interleukin 1β in mice serum, with significant differences in the high dose group (P<0.05, P<0.001, P<0.01). The results of the network pharmacological analysis showed that this compound could act on 78 targets including transcription factor AP-1, interleukin 6 and tumor necrosis factor, regulating 575 GO entries and 272 signalling pathways to exert cough suppressant effects, of which cordycepic acid, cordycepin, apigenin, beta-sitosterol and naringenin were the important material basis. The results indicated that the combination of Citri grandis Exocarpium-Cordyceps militaris has cough suppressant activity, which was the result of the combined action of multiple substances in the combination on multiple targets and pathways.
Background: Gouty arthritis (GA) is a common inflammatory disease that causes pain due to the deposition of monosodium urate (MSU) crystals into joints and surrounding tissues. Anti-inflammatory drugs have significant clinical anti-inflammatory and analgesic effects, but they have many side effects. Cordyceps militaris is an edible and medicinal fungus, and its extract (CME) has good anti-inflammatory and analgesic effects. This study aimed to investigate the anti-inflammatory effect of CME on GA and its underlying mechanism. Methods: The effect of CME on the expression of related inflammatory factors and histopathological changes in the MSU-induced acute inflammatory gout model in rats was studied by ELISA and HE, and its anti-inflammatory mechanism was analyzed by transcriptome combined with RT-qPCR. Results: CME significantly improved gait scores and joint swelling in GA rats, and reduced MSU-induced inflammatory cell infiltration. CME inhibited MSU-induced inflammatory responses by reducing the levels of pro-inflammatory factors TNF-α, IL-1β, IL-6, and Caspase-1 and increasing the anti-inflammatory factor IL-10. Transcriptome analysis showed that CME significantly altered inflammation-related cytokine pathways, and identified four major genes involved in regulation of inflammation, CCL7, CSF2RB, LIF, and IL-1β. In addition, RT-qPCR was performed to verify these differential genes. Conclusion: CME significantly alleviated the inflammatory progression of GA and ameliorated the onset of GA. The underlying mechanism may be related to triggering the cytokine-cytokine receptor interaction signaling pathway to inhibit the activation of the inflammasome and regulate the immune system. And it regulates the inflammatory response induced by MSU crystals through the genes CCL7, CSF2RB, and IL-1β.

The mushroom Ganoderma lucidum is a traditional Chinese medicine and G. lucidum spore oil (GLSO) is the lipid fraction isolated from Ganoderma spores. We examined the effect of GLSO on burn wound healing in mice. Following wounding, GLSO was applied on the wounds twice daily. Repair analysis was performed by Sirius-Red-staining at different time points. Cell proliferation and migration assays were performed to verify the effect of GLSO on growth. Network pharmacology analysis to identify possible targets was also carried out, followed by Western blotting, nuclear translocation, cell proliferation, and immunofluorescence assays for in-depth investigation of the mechanism. Our study showed that GLSO significantly promoted cell proliferation, and network pharmacology analysis suggested that GLSO might act through transient receptor potential vanilloid receptor 1 (TRPV1)/SMAD signaling. Furthermore, GLSO elevated SMAD2/3 expression in skin burn and promoted its nuclear translocation, and TRPV1 expression was also increased upon exposure to GLSO. Cell proliferation and immunofluorescence assays with TRPV1 inhibitor showed that GLSO accelerated skin burn wound healing through TRPV1 and SMADs signaling, which provides a foundation for clinical application of GLSO in the healing of deep skin burns.
Sarcodon imbricatus (S. imbricatus), a well-known edible mushroom, is one of the most commonly consumed wild mushrooms in China because of its nutritional value. Previous studies have demonstrated that S. imbricatus has immunoregulatory activity. We previously described the potential anti-tumor activity of several types of mushrooms, including S. imbricatus. In this study, the results demonstrate that an aqueous extract of S. imbricatus (SIE) effectively inhibits the growth, migration, and invasion properties of breast cancer cells in vitro and reduces tumor growth in vivo. In addition, the SIE increased serum concentrations of interleukin (IL)-2, IL-6 and tumor necrosis factor-α, natural killer cell activity and the viability of splenocytes and reduced the expression of programmed cell death-Ligand 1 (PD-L1) in 4T1 tumor-bearing mice. Collectively, these results are the first demonstration that the SIE has anti-tumor and immunomodulatory effects in the 4T1 mouse breast cancer model. These findings provide a scientific rationale for the potential therapeutic use of S. imbricatus in breast cancer patients.
Ethnopharmacological relevance: The mushroom Ganoderma lucidum (G. lucidum) is a traditional Chinese medicine reported to have a variety of pharmacological properties, including anti-cancer activity. G. lucidum spore oil (GLSO) is a lipid substance extracted from sporoderm-broken spore of G. lucidum. However, the effect of GLSO on breast cancer and the underlying molecular mechanism remain unclear. Aim of the study: The aim of this study was to identify the effects of GLSO on breast cancer cells in vitro and in vivo as well as to investigate the mechanistic basis for the anticancer effect of GLSO. Materials and methods: First, in vitro MDA-MB-231 cells were treated with GLSO (0.2, 0.4, and 0.6 mu L/mL). The protein levels of B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X (Bax), X-linked inhibitor of apoptosis (XIAP), total poly (ADP-ribose) polymerase (PARP), caspase-3 and caspase-8 were examined using western blotting. The mRNA expression levels of Fas-associated protein with death domain (FADD), TNF receptor-associated factor 2 (TRAF2), caspases-3, -8, -9 and Bax were examined using qRT-PCR. Second, in vivo the anticancer properties of GLSO were assessed by H&E, TUNEL and immunohistochemistry in BALB/c mice injected with 4T1 cells. In addition, the levels of caspase-9/caspase-3 signaling pathway proteins in tumor tissue were evaluated by immunoblotting. Finally, MDA-MB-231 cells were treated with caspase inhibitors to measure cell viability, the protein levels were examined with western blotting. Results: The results in vitro showed that GLSO up-regulated the expression of Bax and caspase-3 in MDA-MB-231 cells, but had no effect on the expression of caspase-8. Moreover, the growth of tumors in vivo was significantly suppressed in the GLSO-treated group. The results of Western blot were consistent with in vitro. In vitro, co-treatment of MDA-MB-231 cells with caspase inhibitors reduced the inhibitory effect of GLSO on cell growth. Conclusions: GLSO inhibits the growth of MDA-MB-231 cells and tumors in vivo by inducing apoptosis, which may be achieved through the mitochondrial apoptotic pathway.
