ABSTRACT
Objective:To investigate the targets and possible mechanism of Didangtang in the treatment of bladder cancer. Method:Based on multiple traditional Chinese medicine and disease databases, the network pharmacology was used to screen potential targets, analyze the biological functions of potential targets, and construct a network of "Chinese medicine-target-path-disease". Bioinformatics analysis was applied in population and gene databases, in order to explore the differential expressions of core targets in tissues, distribution in the population and the correlation with prognosis. The in vitro experiment was used to verify the biological function of Didangtang. The underlying mechanism of Didangtang on the candidate target was detected. Result:A total of 21 core target genes and 16 highly enriched pathways were screened out. A functional network of Didangtang was constructed systematically. At the same time, six targets, namely cadherin 1 (CDH1), CAMP responsive element binding protein 1 (CREB1), colony stimulating factor 2 (CSF2), AP-1 transcription factor (JUN), matrix metalloproteinase 2 (MMP2), and prostaglandin-endoperoxide synthase (PTGS2), were differentially expressed in bladder cancer tissues (P<0.05). Furthermore, JUN and MMP2 were also differentially distributed in population (P<0.05). At the same time, the expression level of JUN was correlated with the prognosis of patients with bladder cancer (P<0.05). The in vitro experiment revealed that Didangtang inhibited the proliferation of bladder cancer cells and decreased the expression of candidate target JUN (P<0.01). Conclusion:Didangtang has the characteristics of multiple targets and multiple pathways in treatment of bladder cancer. It is initially confirmed that Didangtang can affect the expression of target JUN and inhibit the proliferation of bladder cancer, which lays a good foundation for further studies on mechanism.
ABSTRACT
Objective::To explore the potential active ingredients and possible anti-breast cancer mechanism of Glycyrrhizae Radix et Rhizome and Aurantii Fructus based on the method of network pharmacology. Method::The main potential targets of Glycyrrhizae Radix et Rhizome and Aurantii Fructus on breast cancer were summarized by comparing the Glycyrrhizae Radix et Rhizome-Aurantii Fructus active ingredients screened from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and breast cancer targets searched in Therapeutic Target Database (TTD). Cytoscape 3.7.1 software was used to establish a Glycyrrhizae Radix et Rhizome-Aurantii Fructus active ingredients-target-disease network and perform topology analysis based on the network. Result::According to related conditions of drug-like (DL) and oral bioavailability (OB), the network of Glycyrrhizae Radix et Rhizome-Aurantii Fructus active ingredients-breast cancer target was obtained, covering a total of 133 nodes, 116 chemical components and 17 breast cancer drug targets, 109 active components of Glycyrrhizae Radix et Rhizome interacting with breast cancer drug target, 6 active ingredients of Aurantii Fructus interacting with breast cancer drug targets, and 1 common active ingredient of Aurantii Fructus and Glycyrrhizae Radix et Rhizome interacting with breast cancer targets. There were 400 breast cancer target-interaction target pairs in the network diagram. Conclusion::The anti-breast cancer effect of Glycyrrhizae Radix et Rhizome and Aurantii Fructus is based on the overall pharmacodynamic effect of multi-component, multi-pathway and multi-target, the investigation of its potential anti-breast cancer mechanism provides theoretical basis for further experimental research.
ABSTRACT
Objective@#To investigate the clinical effects of integrated traditional Chinese and Western medicine in the treatment of castration-resistant prostate cancer (CRPC).@*METHODS@#A total of 54 CRPC patients were randomly divided into a control and a trial group, all treated by endocrine therapy (oral Bicalutamide at 50 mg per d plus subcutaneous injection of Goserelin at 3.6 mg once every 4 wk) and chemotherapy (intravenous injection of Docetaxel at 75 mg/m2 once every 3 wk plus oral Prednisone at 5 mg bid), while the latter group by Fuyang Huayu Prescription (a Traditional Chinese Medicine [TCM] prescription for tonifying yang and dispersing blood stasis) in addition, for a course of 24 weeks. Comparisons were made between the two groups of patients in the level of serum prostate-specific antigen (PSA), Karnofsky physical condition scores, function assessment of cancer therapy-prostate (FACT-P) scores, and TCM symptoms scores before and after 12 or 24 weeks of treatment.@*RESULTS@#Compared with the baseline, the serum PSA level was significantly decreased after 12 weeks of treatment both in the control ([25.9 ± 39.3] vs [20.0 ± 21.1] μg/L, P 0.05). At 24 weeks, however, the PSA levels in the control and trial groups were slightly increased to (23.1 ± 28.4) and (19.6 ± 23.5) μg/L, respectively, with no statistically significant differences in between (P >0.05). Karnofsky, FACT-P and TCM symptoms scores were all markedly improved in the trial group after 12 weeks of treatment (P 0.05).@*CONCLUSIONS@#TCM Fuyang Huayu Prescription combined with endocrine therapy and chemotherapy is effective for CRPC.

Objective@#To explore the apoptosis-inducing effect of the Chinese medicinal compound CFF-1 on prostate cancer cells and its related molecular mechanisms.@*METHODS@#Normal prostate WPMY-1 cells and prostate cancer LNCaP, CWR22Rv1, PC3 and DU145 cells were treated in dehydrated alcohol with CFF-1 at 0, 2, 5, or 10 mg/ml for 24 hours. Then the viability of the prostate cells was detected by morphological observation, MTT and CCK-8 assay, nuclear condensation and disruption measured by DAPI staining, the cell cycle and apoptosis calculated by flow cytometry, the activity of the PI3K/AKT/FOXO1 signaling pathway and the expressions of its downstream apoptosis- and cycle-related proteins determined by Western blot.@*RESULTS@#CFF-1 significantly arrested the cell cycle in the G1 phase, decreased the cell viability and increased the nuclear condensation and disruption in a dose-dependent manner, and elevated the apoptosis rate of prostate cancer cells. At the molecular level, CFF-1 dose-dependently reduced the activity of the PI3K/AKT signaling pathway and phosphorylation of the FOXO1 protein, increased the transcription activity of FOXO1, and eventually regulated the expressions of cell apoptosis- and cycle-related genes.@*CONCLUSIONS@#The Chinese medicinal compound CFF-1 can significantly inhibit the growth, arrest the cycle, and induce the apoptosis of prostate cancer cells by decreasing the activity of the PI3K/AKT/FOXO1 signaling pathway, which suggests its potential clinical application value in the treatment of prostate cancer.
