ObjectiveWith the epidermal growth factor receptor(EGFR)/Signal Transducers and Activators of Transcription(STAT3)/Hexokinase 2(HK2) signaling pathway in atherosclerosis (AS) and ovarian cancer (OC) as the entry point, this paper discusses the molecular mechanism of Gypenoside L (Gyp-L) treating AS and OC with different diseases, provides a new perspective and theoretical basis for TCM treating AS and OC with EGFR-STAT3-HK2 pathway, and enriches the scientific connotation of the theory of "cytoskeleton in the heart". MethodsCCK-8 was used to detect the proliferation of HUVEC and OVCAR-3 cells, in order to determine the intervention concentration for subsequent experiments. The colorimetric method was used to detect the NO content in HUVEC and the contents of pyruvate and LDH in two cell lines. Cell cloning experiments and scratch experiments reflect the proliferation and migration ability of OVCAR-3 cells. Western blot was used to detect the expression levels of relevant proteins. Furthermore, two cell models overexpressing EGFR were constructed and co treated with Gyp-L. HUVEC cells were divided into control, ox-LDL, OE-NC, OE-EGFR, OE-NC+Gyp-L, and OE-EGFR+Gyp-L group. OVCAR-3 cells were divided into control, OE-NC, OE-EGFR , OE-NC+Gyp-L, and OE-EGFR+Gyp-L group. The colorimetric method was used to detect the NO content in HUVEC and the contents of pyruvate and LDH in two cell lines. Western blot was used to detect the expression levels of EGFR-STAT3-HK2 pathway related proteins. Cell cloning experiments and scratch experiments reflect the proliferation and migration ability of OVCAR-3 cells. ResultsGyp-L can significantly reduce the NO content of HUVEC and the pyruvate and LDH content of two cell lines (P<0.05); Inhibit the proliferation and migration ability of OVCAR-3 cells; Reduce the expression levels of EGFR/STAT3/HK2 pathway related proteins in HUVEC and OVCAR-3 cell lines (P<0.05), and inhibit the glycolysis pathway. ConclusionGyp-L can inhibit glycolysis in HUVEC and OVCAR-3 cells through the EGFR/STAT3/HK2 pathway,thereby suppressing the occurrence and development of AS and OC.

Aim To investigate the mechanisms of Chaijin JieYu Anshen formula modulating the depres-sive behaviors and the synaptic plasticity of hippocam-pal neurons in insomnia-concomitant depression rats based on the histone deacetylase 5(HDAC5)/myocyte enhancer factor 2C(MEF2C)pathway.Methods A rat model of insomnia-concomitant depression was es-tablished by PCPA injection combined with chronic un-predictable mild stress(CUMS),and the experiment was divided into the control group,the model group,the high,medium and low dose group of Chaijin JieYu Anshen formula,and the positive drug group.The de-pression of rats was evaluated by sugar-water prefer-ence test,open field test and morris water maze.The levels of 5-hydroxytryptamine(5-HT)and dopamine(DA)in serum were measured by enzyme linked im-munosorbent assay(ELISA).The pathological damage of hippocampal neurons was observed by HE staining and Nissl staining.The damage of dendritic spines of hippocampal neurons was observed by Golgi staining,and the levels of HDAC5,MEF2C,postsynaptic densi-ty-95(PSD-95)and synaptophysin 1(SYN1)in hip-pocampus were measured by Western blot,immunohis-tochemistry and immunofluorescence.Results Com-pared with the model group,the Chaijin JieYu Anshen formula could increase the sugar-water preference rate of the model rats,reduce the immobility time in the open field experiment,increase the total activity dis-tance,shorten the evasion latency in the localization navigation experiment,and prolong the residence time in the quadrant where the platform was located in the space exploration experiment(P<0.05,P<0.01).Moreover,the Chaijin JieYu Anshen formula improved the hippocampal neuron and dendritic spine damage and increase the dendritic branch length and dendritic spine density of hippocampal neurons(P<0.01,P<0.01),restore the serum levels of 5-HT and DA in insomnia-concomitant depression rats(P<0.05,P<0.01),down-regulate the HDAC5 protein,and up-regulate the expression of MEF2C,PSD-95,and SYN1 protein(P<0.05,P<0.01 or P<0.001).Conclusions Chaijin JieYu Anshen formula may alle-viate the depression-like behavior of model rats by re-ducing the expression of HDAC5 protein,thus deregu-lating the inhibition of transcription factor MEF2C,promoting the expression of PSD-95 and SNY1 protein,and exerting a protective effect on hippocampal neurons and synapses.

Aim This study aims to investigate the therapeutic effect and underlying mechanism of Todda-lia asiatica in the treatment of ischemic stroke(IS),utilizing network pharmacology,molecular docking technology,and animal experiments.Methods To screen the chemical components of Toddalia asiatica and its targets related to IS,a database was utilized.A protein-protein interaction(PPI)network was con-structed,followed by KEGG pathway enrichment anal-ysis.Molecular docking was performed to investigate the interaction between the components and target pro-teins.Finally,the effects of the drug on the PI3K/AKT/mTOR pathway and autophagy were validated through animal experiments.We established a middle cerebral artery occlusion(MCAO)rat model and di-vided the rats into the model group,Donepezil hydro-chloride group,Toddalia asiatica group,and sham op-eration group randomly.Observed the pathological changes in neurons of the rat hippocampal and cortical regions induced by the drug,performed immunohisto-chemical analysis to detect and localize mTOR expres-sion,and used Western blot to assess the expression levels of PI3K,p-PI3K,AKT,p-AKT,mTOR,as well as autophagy markers(LC3-Ⅱ and p62).Re-sults A total of 22 active ingredients from Toddalia asiatica,including AKT1 and MAPK3,were identified through screening.Additionally,194 signaling path-ways,such as PI3K/AKT and MAPK,were analyzed.The active compounds in Toddalia asiatica demonstra-ted stable binding affinity with targets associated with ischemic stroke.The results of the animal experiment indicated that,compared to the sham-operated group,the neuronal distribution in the hippocampal and corti-cal regions of the model group rats became sparser and more disorganized.There was a decrease in the number of Nissl bodies and cytoplasmic vacuolization.The ex-pression of mTOR-positive cells in the hippocampal and cortical regions was reduced.Additionally,the ex-pression levels of p-PI3K,p-AKT,mTOR,and p62 in the rat hippocampal tissue decreased(P<0.05,P<0.01),while the expression of LC3-Ⅱ increased(P<0.01).Compared with the model group,the rats in the Toddalia asiatica and the Donepezil hydrochloride groups effectively improved the aforementioned indica-tors in rats.Conclusions Network pharmacology a-nalysis has revealed the promising potential of Toddalia asiatica in treating ischemic stroke,attributed to its di-verse components,targets,and pathways.The animal experiment showed that Toddalia asiatica can protect the neuronal structure in the hippocampal and cortical regions,which may be related to the inhibition of ex-cessive autophagy mediated by the PI3 K/AKT/mTOR pathway.
