Ginsenosides, extracted from the root of Panax ginseng C.A. Mey, have demonstrated the potential to mitigate depression associated with GC dysregulation. This study evaluated the therapeutic efficacy of ethanol extract of P. ginseng (PG) in treating depression and its underlying FKBP51-linked mechanism. Using chronic unpredictable stress, a depression model was developed in Kunming mice to test the efficacy of PG by observing changes in behaviors and protein expression in depressed mice. The mechanism of action was investigated through transfection with HEK293T cells. Depressed mice treated with PG demonstrated notable improvements: the rate of weight loss was reduced, sucrose preference and open-field activity were enhanced, and the rate of apoptosis in hippocampal cells was decreased. Additionally, the HPA axis function appeared to be restored. These physiological adjustments coincided with an increase in GR levels and a decrease in FKBP51 levels. Altogether, these results suggested that PG treatment effectively alleviates depressive symptoms in mice. PG also moderated FKBP51-GR interaction, lessening FKBP51's restraint on GR nuclear entry. This modulation may enhance the sensitivity of the GR response, reinforcing the negative feedback regulation of the HPA axis and thereby reducing depressive symptoms in mice. These findings highlight the potential of PG as a promising curative treatment for depression, providing a basis for the development of innovative treatments targeting the FKBP51-GR pathway.</p>","PeriodicalId":20110,"journal":{"name":"Phytotherapy Research","volume":" ","pages":"5016-5029"},"PeriodicalIF":6.1,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142293208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Curcumin, the active ingredient of the turmeric plant, has been gaining attention over the past two decades as an antioxidant, anti-inflammatory, and anticancer agent. In the present study, the HPV-positive cervical cancer cells HeLa and CaSki were treated with curcumin, and the results showed that curcumin has a dose-dependent and time-dependent inhibitory effect on cell viability. In addition, apoptosis induction was further quantitatively confirmed through flow cytometric analysis. Furthermore, the influence of different concentrations of curcumin on the mitochondrial membrane potential was evaluated through JC-1 staining and found to dramatically decrease the membrane potential in treated HeLa and CaSki cells, suggesting the critical role of the mitochondrial pathway in their apoptosis-inducing effect. This study also demonstrated the wound-healing potential of curcumin, and the results of transwell assays showed that curcumin treatment inhibited HeLa and CaSki cell invasion and migration in a dose-dependent manner compared with the control treatment. Curcumin also downregulated the expression of Bcl-2, N-cadherin, and Vimentin and upregulated the expression of Bax, C-caspase-3, and E-cadherin in both cell lines. Further research showed that curcumin also selectively inhibited the expression of the viral oncoproteins E6 and E7, as demonstrated by western blot analysis; moreover, the downregulation of E6 was more significant than that of E7. Our research also showed that coculture with cells infected with siE6 lentivirus (siE6 cells) can inhibit the proliferation, invasion, and metastasis of HPV-positive cells. While the siE6 cells were also treated with curcumin, the effect of curcumin monotherapy was offset. In summary, our research shows that curcumin regulates the apoptosis, migration, and invasion of cervical cancer cells, and the mechanism may be related to its ability to downregulate E6.

We investigated the protective effect and potential mechanism of OA on EP-induced hepatorenal toxicity. In this study, rats were given total diterpenes from EP (TDEP, 16 mg/kg) combined with OA (10, 20, 40 mg/kg) by gavage for 4 weeks. The results showed that TDEP administration could lead to a 3-4-fold increasement in hepatorenal biochemical parameters with histopathological injuries, while OA treatment could ameliorate them in a dose-dependent manner. At microbial and metabolic levels, intestinal flora and host metabolism were perturbed after TDEP administration. The disturbance of bile acid metabolism was the most significant metabolic pathway, with secondary bile acids increasing while conjugated bile acids decreased. OA treatment can improve the disorder of intestinal flora and metabolic bile acid spectrum. Further correlation analysis screened out that Escherichia-Shigella, Phascolarctobacterium, Acetatifactor, and Akkermansia were closely related to the bile acid metabolic disorder.

The viability of chondrocytes after exposure to ESC was examined through the CCK-8 assays. The cells were then subjected to quantitative polymerase chain reaction (qPCR), western blot, and enzyme-linked immunosorbent assay (ELISA) techniques to analyze the degradation of the extracellular matrix (ECM) and occurrence of inflammation. The NF-κB mechanism was evaluated by western blot analysis, immunofluorescence (IF), and luciferase reporter assay. Molecular docking was performed to allow for predictions on proteins that interact with ESC. Moreover, the significance of Sirt1 was explored through a knockdown experiment based on siRNA. Micro-computed tomography (CT), H&E, Safranin O-Fast Green (S-O), and immunohistochemical analyses were carried out to assess the treatment efficacy of ESC on OA in destabilization of medial meniscus (DMM) models. ESC treatment effectively inhibited ECM degradation, modulated the levels of pro-inflammatory factors, and regulated the NF-κB signaling in chondrocytes exposed to IL-1β. Mechanistically, we found that ESCs bound to Sirt1 to inhibit the activity of the NF-κB mechanism. Furthermore, ESC treatment suppressed OA progression in the DMM models. Our findings reveal that ESC ameliorates OA progression via modulating the Sirt1/NF-κB axis.

Preclinical studies have shown that organosulfur compounds from the Alliaceae and Brassicaceae plants, such as garlic (Allium sativum L.) and broccoli (Brassica oleracea L.), have potential lipid-lowering effects. However, their clinical efficacy is controversial, especially in \"drug-free\" patients. The aim of this work was to summarize evidence on the lipid-lowering properties of extracts containing organosulfur compounds in patients with dyslipidemia. Studies were searched in four databases (Medline, Scopus, Embase, and CENTRAL), from inception to October 11, 2023.Controlled clinical studies on patients with dyslipidemia receiving Alliaceae or Brassicaceae were included. The outcome was the change in lipid parameters from baseline. Random-effect meta-analysis of the extracted data was performed using R software. The effect size was expressed as mean difference (MD) and 95% confidence interval (CI). The certainty of evidence was assessed with the GRADE approach. Out of 28 studies that were reviewed, 22 were included in the meta-analysis (publication period: 1981-2022). Results showed that Alliaceae extracts significantly reduce total cholesterol [MD: -15.2 mg/dL; 95% CI: -21.3; -9.1] and low-density lipoprotein cholesterol levels [MD: -12.0 mg/dL; 95% CI: -18.1; -5.7], although with low certainty of evidence. Conversely, the lipid-lowering properties of Brassicaceae extracts are still unexplored. Our results support the use of Alliaceae extracts in patients with hypercholesterolemia, but future high-quality studies are needed.
