Abstract
The classical cadherin gene has been linked to a variety of human malignancies, including gastric cancer. However, the link between cadherin genes and gastric cancer outcome is still unclear. This study used multi-omics data to examine the cadherin genes that were differentially regulated in gastric cancer. Differential expression of genes, epigenetic, molecular alterations, and protein expression analyses was conducted. Male SD rats were given N-methyl-N-nitrosourea (MNU) to induce stomach carcinoma in order to verify the activation of cadherin genes. CDH5, CDH6, CDH11, and CDH24 levels were found to be considerably higher in gastric cancer and may serve as useful indicators of stomach adenocarcinoma (STAD). Cadherin genes with variable expression had considerably more promoter methylation in cancers than in normal tissues. In individuals with gastric cancer, high expression of these cadherin genes was related to lower total mortality and disease-free survival rates. Furthermore, compared to normal rats, gastric cancer-induced rats had significantly higher expression and distribution of CDH5, CDH6, CDH11, and CDH24. This study sheds new light on the diagnosis and prognosis of gastric cancer by identifying potential prognostic markers such as CDH5, CDH6, CDH11, and CDH24. The multi-omics approach provided a potential tool for target-based therapy by accurately predicting the outcome of stomach cancer. Researchers may gain more knowledge about the role of cadherin genes in the development and dissemination of tumors to the activated rat model of gastric cancer.

LC-MS metabolomic evidence metabolites from Oenothera rosea L´ Hér. ex Ait with antiproliferative properties on DU145 human prostate cancer cell line. Biomed Pharmacother 2023; 165:115193. [PMID: 37517287 DOI: 10.1016/j.biopha.2023.115193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 06/25/2023] [Accepted: 07/18/2023] [Indexed: 08/01/2023] Open
Abstract
Prostate cancer remains one of the leading health issues without a fully effective treatment. Medicinal plants are one of the primary sources of compounds for treating numerous ailments. In this sense, the Oenothera genus contains metabolites with antiproliferative activity on cancer cells. For this, the study aimed to explore the antiproliferative activity of its extracts against prostate cancer and identify its metabolites (under metabolomics analyses) associated with anticancer and/or antiproliferative properties. For this reason, a LC-MS/MS-based metabolomic analysis was performed to demonstrate the possible metabolites present in O. rosea. In addition, the antiproliferative activity of different extracts in the human prostate cancer cell line DU145 was evaluated. All extracts have antiproliferative effects on DU145 cells at 72 h, with moderate activity being the best ethanolic either 48 or 72 h. Finally, by LC-MS/MS-based metabolomics, 307 compounds from aqueous, methanolic, ethanolic, and ethyl acetate extracts from which 40 putative metabolites identified were organized as anti-inflammatory, anticancer, and/or antiproliferative activities according to previously reported. These results provide evidence that O. rosea could be used as an antiproliferative agent due to its chemical contents used as polypharmacy with low concentration levels.

Xiao Q, Deng B, Akbari A, Liu Q, Zhu B. The ketogenic diet could improve the efficacy of curcumin and Oldenlandia diffusa extract in the treatment of gastric cancer by increasing miR340 expression and apoptosis mediated by autophagy, oxidative stress, and angiogenesis. J Food Biochem 2022; 46:e14407. [PMID: 36219718 DOI: 10.1111/jfbc.14407] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 08/03/2022] [Accepted: 08/30/2022] [Indexed: 01/13/2023]
Abstract
The pathogenesis of gastric cancer is a multistage process that involves glucose metabolism, inflammation, oxidative damage, angiogenesis, autophagy, and apoptosis. Moreover, microRNA-340 (miR340) also plays a vital role in tumorigenesis and the biology of gastric cancer as an epigenetic factor. It seems that the use of ketogenic diets (KDs) and plant extracts that have antitumor, anti-inflammatory, and antioxidant properties can be good treatment options to cure gastric cancer. The aim of this study was to investigate the role of miR-340 on pathways involved in the pathogenesis of gastric cancer and the improving effects of the KD, Oldenlandia diffusa extract (ODE), and curcumin in the animal model of gastric cancer. One hundred and ten male Wistar rats were divided into control and treatment groups. The expression of miR-340 along with genes involved in inflammation, oxidative damage, angiogenesis, and apoptosis were assessed. The results showed that the KD and different doses of curcumin and ODE in a dose-dependent behavior could induce apoptosis and the expression of the Akt/mTORC1 pathway and inhibit inflammation, oxidative damage, and angiogenesis in the gastric tissue of rats with cancer. In addition, there was no significant difference between cancer groups receiving ODE and curcumin. These results also showed that consumption of KD could significantly increase the efficacy of ODE and curcumin which may be due to increasing miR-340 expression. The results of this study suggested well that the KD along with conventional therapies in traditional medicine can be a useful solution for the prevention and treatment of gastric cancer. PRACTICAL APPLICATIONS: Gastric cancer is the third leading cause of cancer death, and genetic and epigenetic factors, including miR-340, are involved in its pathogenesis. However, the use of ketogenic diets (KDs) and plant products such as curcumin and Oldenlandia diffusa extract (ODE) can play an effective role in inhibiting tumorigenesis in some cancers. Our results showed that the KD and different doses of curcumin and ODE could induce apoptosis and the expression of the Akt/mTORC1 pathway and inhibit inflammation, oxidative damage, and angiogenesis in the gastric tissue. Moreover, the KD could significantly increase the efficacy of ODE and curcumin which may be due to an increase in miR-340 expression. These findings provide novel perceptions about the mechanisms of the KD, curcumin, and ODE to cure gastric cancer. It suggested that the KD as adjunctive therapy along with conventional therapies in traditional medicine could be considered a useful solution to prevent and treat gastric cancer.

AVICENNA JOURNAL OF PHYTOMEDICINE 2022; 12:401-413. [PMID: 35782768 PMCID: PMC9121262 DOI: 10.22038/ajp.2022.19616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/17/2021] [Revised: 09/26/2021] [Accepted: 11/08/2021] [Indexed: 11/25/2022]
Abstract
OBJECTIVE This study was conducted to investigate the antinociceptive and anti-inflammatory effect of ethyl acetate fraction of Oenothera rosea (EAOr) and the mechanism involved, in mice. MATERIALS AND METHODS The antinociceptive activity was tested using chemical- and heat-induced nociception models. The anti-inflammatory activity was tested using carrageenan-induced edema and inflammatory cytokines were measured. RESULTS EAOr reduced the licking time on the second phase of the formalin test (100 and 177 mg/kg). The antinociception of EAOr was prevented by L-NAME (10 mg/kg), 1H-[1, 2, 4]-oxadiazolo [4, 3-a]-quinoxalin-1-one (ODQ, 0.1 mg/kg), glibenclamide (10 mg/kg) and bicuculline (1 mg/kg), but not by naloxone (2 mg/kg). Also, EAOr decreased licking time in capsaicin induced-nociception. EAOr did not have effect on withdrawal latency in tail-flick test. Carrageenan-induced paw edema was reduced by EAOr, and TNF-α and IL-1β levels were reduced in mice treated with EAOr by 72.2 and 32.8%, respectively. Furthermore, EAOr did not present side effects as sedation nor gastric injury. Chemical analysis of this fraction showed the presence of glycosylated quercetin derivatives such as quercetin glucoside and quercetin rhamnoside in a 2.5% concentration. CONCLUSION This study demonstrates antinociceptive and anti-inflammatory effect of an organic fraction of O. rosea and its possible interaction with the NO-cGMP-K+ channels and GABAergic system and thus, it could be considered a therapeutic alternative.

Abstract
Despite the availability of many anti-pain drugs, in the form of NSAIDs, steroids, gabapentinoids, opioids, and antidepressants, in this study we address the natural compounds belonging to the group of Mexican medicinal plants or "Mexican folk medicine", used for pain management in Mexico. Our interest in this subject is due to the growing idea that "natural is harmless" and to the large number of side effects exhibited in pharmacotherapy. The objective of this review was to document the scientific evidence about Mexican medicinal plants and their derivatives used for inflammatory and neuropathic pain treatment, as well as the mechanisms of action implicated in their antinociceptive effects, their possible adverse effects, and the main pharmacological aspects of each plant or compound. Our data review suggested that most studies on Mexican medicinal plants have used inflammatory experimental models for testing. The anti-pain properties exerted by medicinal plants lack adverse effects, and their toxicological assays report that they are safe to consume; therefore, more studies should be performed on preclinical neuropathic pain models. Moreover, there is no convincing evidence about the possible mechanisms of action involved in the anti-pain properties exerted by Mexican plants. Therefore, the isolation and pharmacological characterization of these plant derivatives' compounds will be important in the design of future preclinical studies.

Antioxidant Activity of Sprouts Extracts Is Correlated with Their Anti-Obesity and Anti-Inflammatory Effects in High-Fat Diet-Fed Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:8367802. [PMID: 33643424 PMCID: PMC7902152 DOI: 10.1155/2021/8367802] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 01/22/2021] [Accepted: 01/30/2021] [Indexed: 01/24/2023]
Abstract
Obesity is closely associated with oxidative stress and chronic inflammation leading to related metabolic diseases. Some natural extracts or polyphenols reportedly possess anti-obesity and anti-inflammatory effects as well as antioxidant activity. In this study, we assessed the correlations between the antioxidant, anti-obesity, and anti-inflammatory activities of plant extracts with potent antioxidant activity in diet-induced obese mice. Sprouts of Cedrela sinensis (CS) and Oenothera biennis L. (OB) were selected as the most potent antioxidant plant based on analysis of in vitro antioxidant activity of the extracts of ten different edible plants. C57BL/6 mice were fed with a high-fat diet (HFD) and orally treated with 50% ethanol extract of CS or OB at 50 or 100 mg/kg body weight 5 days a week for 14 weeks. Body weight gain, weight of adipose tissue, adipocyte size, and levels of lipid metabolism, inflammation, and oxidative stress markers were investigated. The CS or OB extract reduced body weight gain, visceral adipose tissue weight, adipocyte size, and plasma leptin levels, and expressions of adipogenic genes (PPARγ and fatty acid synthase) in the adipose tissue and liver of HFD-fed mice. Both extracts also reduced mRNA levels of pro-inflammatory cytokines (IL-6 and TNF-α) and oxidative stress-related genes (heme oxygenase- (HO-) 1 and p40phox). Body weight gain of mice was significantly correlated with visceral adipose tissue weight and adipocyte size. Body weight gain and adipocyte size were significantly correlated with plasma total cholesterol and 8-epi PGF2α levels, mRNA levels of leptin, HO-1, p40phox, and CD-11 in the adipose tissue, and mRNA levels of TNF-α in the adipose tissue and liver. These results suggest that the CS and OB extracts with potent antioxidant activity may inhibit fat deposition in adipose tissue and subsequent inflammation.

Abstract
Background and objective Chuquiraga spinosa Lessing (ChS) has shown protective effect on N-Nitroso-N-methylurea (NMU)-induced prostate cancer in rats. Currently, statins are being studied for their pro-apoptotic and antimetastatic effects. The main objective of this research was to determine the protective effect associated with the oral administration of simvastatin and ethanolic extract of the aerial parts of ChS in the prevention of prostate cancer. Methods Fifty-six albino male rats were randomized into seven groups: I) negative control: physiological serum: 2 mL/kg; II) TCN: testosterone 100 mg/kg + cyproterone 50 mg/kg + NMU 50 mg/kg; III) TCN + S40 (simvastatin 40 mg/kg); IV) TCN + ChS250 (ChS 250 mg/kg); V) TCN + ChS50 (ChS 50 mg/kg) + S40; VI) TCN + ChS250 (ChS 250 mg/kg) + S40; and VII) TCN + ChS500 (ChS 500 mg/kg) + S40. The antioxidant activity was tested by using (2,2-diphenyl-1-picrylhydrazyl) (DPPH) assay. Hematology, toxicological biochemical parameters, prostate-specific antigen (PSA), histology and prostate size were evaluated as main indicators of protective effect. Results Triglyceride values were decreased in the groups receiving ChS, being significant (P=0.02) in IV and VII group compared to cancer-inducing group (TCN). In groups that received ChS, PSA levels (P=0.71) were significant compared with TCN group. The VII group had the lowest prostate volume by sonography. The TCN group showed multiple foci of high-grade prostatic intraepithelial neoplasia (HG-PIN) with the presence of cells in mitosis; whilst, groups V and VI had few areas of HG-PIN. Conclusion In experimental conditions, the ethanolic extract of C. spinosa in association with simvastatin showed a protective effect on prostate cancer through hypolipidemic and antioxidant activity.

Abstract
BACKGROUND According to the latest statistics from the American Cancer Society, there will be 1.73 million cancer cases and more than 600 000 cancer deaths in the United States in 2018, among which there will be 26 240 new cases of gastric cancer and around 10 800 deaths arising from gastric cancer. The objective of this study was to use RAA-11 to intervene in SGC-7901 cells to understand its effects on cell proliferation and apoptosis, and to explore the apoptosis mechanism. MATERIAL AND METHODS MTT assay was used to detect the survival of human gastric mucosal epithelial GES-1 cells and human gastric cancer SGC-7901 cells. Colony formation assay was used to observe the colony forming ability in SGC-7901 cells. The apoptotic rate of SGC-7901 cells was evaluated by Hoechst33258 staining and flow cytometry. qRT-PCR was used to analyze the epidermal growth factor receptor (EGFR) mRNA expression level in SGC-7901 cells. Western blot was used to examine the expression levels of caspase-3, Bcl-2, BAX, EGFR, Akt, p-Akt, and NF-κB in SGC-7901 cells. RESULTS RAA-11 is capable of inhibiting the proliferation and inducing the apoptosis of SGC-7901 cells in a time- and dose-dependent manner. Western blot showed that the expression levels of caspase-3 and BAX were upregulated, while the expression levels of Bcl-2, EGFR, Akt, p-Akt, and NF-κB in the SGC-7901 cells were downregulated. CONCLUSIONS Apoptosis can be induced in SGC-7901 cells by RAA-11, potentially via the EGFR/Akt/NF-κB pathway, indicating that RAA-11 might be a potent agent for cancer treatment.

Abstract
Colorectal carcinogenesis (CRC) imposes a major health burden in developing countries. It is the third major cause of cancer deaths. Despite several treatment strategies, novel drugs are warranted to reduce the severity of this disease. Adenomatous polyps in the colon are the major culprits in CRC and found in 45% of cancers, especially in patients 60 years of age. Inflammatory polyps are currently gaining attention in CRC, and a growing body of evidence denotes the role of inflammation in CRC. Several experimental models are being employed to investigate CRC in animals, which include the APCmin/+ mouse model, Azoxymethane, Dimethyl hydrazine, and a combination of Dextran sodium sulphate and dimethyl hydrazine. During CRC progression, several signal transduction pathways are activated. Among the major signal transduction pathways are p53, Transforming growth factor beta, Wnt/β-catenin, Delta Notch, Hippo signalling, nuclear factor erythroid 2-related factor 2 and Kelch-like ECH-associated protein 1 pathways. These signalling pathways collaborate with cell death mechanisms, which include apoptosis, necroptosis and autophagy, to determine cell fate. Extensive research has been carried out in our laboratory to investigate these signal transduction and cell death mechanistic pathways in CRC. This review summarizes CRC pathogenesis and the related cell death and signal transduction pathways.
