[PMID: 37792223 DOI: 10.1007/s10555-023-10136-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 09/07/2023] [Indexed: 10/05/2023]
Abstract
Tumor cells employ multiple signaling mediators to escape the hypoxic condition and trigger angiogenesis and metastasis. As a critical orchestrate of tumorigenic conditions, hypoxia-inducible factor-1 (HIF-1) is responsible for stimulating several target genes and dysregulated pathways in tumor invasion and migration. Therefore, targeting HIF-1 pathway and cross-talked mediators seems to be a novel strategy in cancer prevention and treatment. In recent decades, tremendous efforts have been made to develop multi-targeted therapies to modulate several dysregulated pathways in cancer angiogenesis, invasion, and metastasis. In this line, natural compounds have shown a bright future in combating angiogenic and metastatic conditions. Among the natural secondary metabolites, we have evaluated the critical potential of phenolic compounds, terpenes/terpenoids, alkaloids, sulfur compounds, marine- and microbe-derived agents in the attenuation of HIF-1, and interconnected pathways in fighting tumor-associated angiogenesis and invasion. This is the first comprehensive review on natural constituents as potential regulators of HIF-1 and interconnected pathways against cancer angiogenesis and metastasis. This review aims to reshape the previous strategies in cancer prevention and treatment.

Abstract
BACKGROUND Chronic renal failure (CRF) is the result of kidney damage. Puerarin is a flavonoid with specific nephroprotective effect, but its effect on CRF needs further research. This study explored the effect of puerarin on CRF and the potential molecular mechanism. METHODS Adenine was used to establish an in vivo CRF model in rats, and rats were intragastrically administered with puerarin at a dose of 400 mg/kg body weight once a day from day 1 to day 28. Hematoxylin and eosin (HE) and Masson staining were used to observe the morphology and fibrosis of kidney tissue. Lipopolysaccharide (LPS) (400 ng/mL)/H2O2 (200 µM) was applied to human kidney 2 (HK-2) cells to construct an in vitro CRF model. Enzyme-linked immunosorbent assay (ELISA) was performed to validate interleukin (IL)-1β and IL-18 levels. Quantitative reverse transcription polymerase chain reaction (RT-qPCR) was performed to detect microRNA (miR)-342-3p levels. Transforming growth factor beta (TGF-β)1, SMAD2, SMAD3, and pyroptosis marker proteins were detected by Western blot. The interaction between miR-342-3p and TGF-β/SMAD was determined by a dual-luciferase reporter gene assay. Cell Counting Kit-8 (CCK-8) assay was utilized to determine cell viability. RESULTS In the CRF model, puerarin alleviated renal injury and fibrosis and reduced creatinine (Cr) and blood urea nitrogen (BUN) levels. At the same time, miR-342-3p was downregulated, while the TGF-β/SMAD axis was activated and levels of IL-1β and IL-18 were increased. After treatment of CRF rats with puerarin, the expression level of miR-342-3p was increased, the TGF-β/SMAD axis was inhibited, and the secretion of IL-1β and IL-18 was decreased. MiR-342-3p directly bound to and negatively regulated the expression of TGF-β1, SMAD2, and SMAD3. In the in vitro CRF model, miR-342-3p inhibited HK-2 cell pyroptosis by inhibiting the TGF-β/SMAD axis. CONCLUSION Puerarin reduced renal injury and pyroptosis in CRF rats by targeting the miR-342-3p/TGF-β/SMAD axis.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest solid tumors and is resistant to immunotherapy. B cells play an essential role in PDAC progression and immune responses, both locally and systemically. Moreover, increasing evidence suggests that microbial compositions inside the tumor, as well as in the oral cavity and the gut, are important factors in shaping the PDAC immune landscape. However, the gut-associated lymphoid tissue (GALT) has not previously been explored in PDAC patients. In this study, we analyzed healthy vermiform appendix (VA) from 20 patients with PDAC and 32 patients with colon diseases by gene expression immune profiling, flow cytometry analysis, and microbiome sequencing. We show that the VA GALT of PDAC patients exhibits markers of increased inflammation and cytotoxic cell activity. In contrast, B cell function is decreased in PDAC VA GALT based on gene expression profiling; B cells express significantly fewer MHC class II surface receptors, whereas plasma cells express the immune checkpoint molecule HLA-G. Additionally, the vermiform appendix microbiome of PDAC patients is enriched with Klebsiella pneumoniae, Bifidobacterium animalis, and Adlercreutzia equolifaciens, while certain commensals are depleted. Our findings may suggest impaired B cell function within the GALT of PDAC patients, which could potentially be linked to microbial dysbiosis. Additional investigations are imperative to validate our observations and explore these potential targets of future therapies.

THE TURKISH JOURNAL OF GASTROENTEROLOGY : THE OFFICIAL JOURNAL OF TURKISH SOCIETY OF GASTROENTEROLOGY 2023; 34:1107-1115. [PMID: 37860833 PMCID: PMC10724805 DOI: 10.5152/tjg.2023.23169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Accepted: 08/31/2023] [Indexed: 10/21/2023]
Abstract
BACKGROUND/AIMS Chemotherapy is an essential avenue for curing malignancies; however, tumor cells acquire resistance to chemotherapeutic agents, eventually leading to chemotherapy failure. At present, paclitaxel (PTX) resistance seriously hinders the therapeutic efficacy of gastric cancer (GC). Investigating the molecular mechanism of PTX resistance in GC is critical. This study attempted to delineate the impact of MCM10 on GC resistance to PTX and its mechanism in GC. MATERIALS AND METHODS The expression of minichromosome maintenance complex component 10 (MCM10) in GC tissues, its enrichment pathways, and its correlation with glycolysis marker genes and stemness index (mRNAsi) were analyzed in a bioinformatics effort. Real-time quantitative polymerase chain reaction was used to assay the expression of MCM10 in cells. Cell counting kit-8 (CCK-8) was used to analyze cell viability and calculate the 50% inhibitor concentration (IC50) value. Western blot was used to measure the expression of MCM10, Hexokinase 2 (HK2) and stemness-related factors in cells. Sphere-forming assay was performed to study cell sphere-forming ability. Seahorse XF 96 was utilized to measure cell extracellular acidification and oxygen consumption rates. The content of glycolysisrelated products was tested with corresponding kits. RESULTS MCM10 was significantly upregulated in GC and enriched in the glycolysis pathway, and it was positively correlated with both glycolysis-related genes and stemness index. High expression of MCM10 increased sphere-forming ability of drug-resistant cells and GC resistance to PTX. The stimulation of PTX resistance and drug-resistant cell stemness in GC by high MCM10 expression was mediated by the glycolysis pathway. CONCLUSION MCM10 was upregulated in GC and drove stemness and PTX resistance in GC cells by activating glycolysis. These findings generated new insights into the development of PTX resistance in GC, implicating that targeting MCM10 may be a novel approach to improve GC sensitivity to PTX chemotherapy.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 306:116144. [PMID: 36649849 DOI: 10.1016/j.jep.2023.116144] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Revised: 12/28/2022] [Accepted: 01/02/2023] [Indexed: 06/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pueraria lobata (Willd.) Ohwi and Pueraria lobata var. Thomsonii (Benth.) Maesen are essential medicinal and edible homologous plants widely cultivated in Asian countries. Therefore, P. lobata and P. thomsonii are widely used in the food, health products and pharmaceutical industries and have significant domestic and international market potential and research value. P. lobata and P. thomsonii have pharmacological effects in the clinic, such as antipyretic, analgesic, anti-inflammatory and antioxidant effects. These plants are commonly used in the treatment of inflammatory diseases and other related diseases. However, the potential mechanisms of the anti-inflammatory effects of P. lobata and P. thomsonii have not been elucidated. AIM OF THE STUDY This study aimed to confirm the anti-inflammatory effects of P. lobata and P. thomsonii on inflammatory model diseases and to investigate the mechanism of their anti-inflammatory effects from the perspective of plasma metabolomics. MATERIALS AND METHODS First, P. lobata and P. thomsonii were identified by high‒performance liquid chromatography (HPLC). Second, we established the following three inflammation models: an acute inflammation model of auricular swelling in mice induced by xylene, an acute inflammation model of foot swelling in rats induced by carrageenan gum, and a chronic inflammation model of cotton ball granuloma in rats. Then we examined the weight and swelling rate of auricular swelling in mice; the residence time, contact area, and mean contact pressure in rats on the gait meter; and the weight of granulomas in rats and the content of IL-1β and TNF-α in plasma to investigate the anti-inflammatory pharmacodynamics of P. lobata and P. thomsonii. Third, we used LC‒MS‒based plasma metabolomics techniques to obtain potential biomarkers of P. lobata and P. thomsonii related to inflammation. Then, the potential biomarkers were enriched by MetaboAnalyst and KEGG metabolomics analysis tools to obtain metabolic pathways related to inflammation. Finally, we tested the indicators of COX-2, 5-LOX, GSH, GSSG and γ⁃GCL in rat plasma from the granuloma model by enzyme-linked immunosorbent assays (ELISAs) to verify the inflammation-related metabolic pathway. RESULTS The experimental results showed that P. lobata and P. thomsonii could reduce the swollen weight and swelling rate of the auricle in mice, and could increase the residence time, contact area and mean contact pressure in rats on the gait meter. Moreover, P. lobata and P. thomsonii could inhibit the growth of granulomas and reduce the content of IL-1β and TNF-α in plasma in rats. The above results preliminarily verified that P. lobata and P. thomsonii have different anti-inflammatory effects. We identified eighteen plasma biomarkers associated with P. lobata and sixteen plasma biomarkers related to P. thomsonii in regulating inflammation by a plasma metabolomics analysis. The following two major metabolic pathways were further screened and enriched: arachidonic acid metabolism and glutathione metabolism. Then we noted that P. lobata and P. thomsonii could reduce the COX-2, 5-LOX and GSSG levels and increase the GSH, GSH/GSSG and γ⁃GCL levels based on the ELISA results, which demonstrated that P. lobata and P. thomsonii affect the anti-inflammatory mechanism through arachidonic acid metabolism and glutathione metabolism. CONCLUSIONS The results of this study further elucidate the anti-inflammatory mechanism of action of P. lobata and P. thomsonii, providing a scientific basis for developing new drugs for the treatment of inflammation-related diseases and laying a foundation for the development of herbal resources, such as P. lobata and P. thomsonii.

Abstract
Phenolic compounds are natural substances that are produced through the secondary metabolism of plants, fungi, and bacteria, in addition to being produced by chemical synthesis. These compounds have anti-inflammatory, antioxidant, and antimicrobial properties, among others. In this way, Brazil represents one of the most promising countries regarding phenolic compounds since it has a heterogeneous flora, with the presence of six distinct biomes (Cerrado, Amazon, Atlantic Forest, Caatinga, Pantanal, and Pampa). Recently, several studies have pointed to an era of antimicrobial resistance due to the unrestricted and large-scale use of antibiotics, which led to the emergence of some survival mechanisms of bacteria to these compounds. Therefore, the use of natural substances with antimicrobial action can help combat these resistant pathogens and represent a natural alternative that may be useful in animal nutrition for direct application in food and can be used in human nutrition to promote health. Therefore, this study aimed to (i) evaluate the phenolic compounds with antimicrobial properties isolated from plants present in Brazil, (ii) discuss the compounds across different classes (flavonoids, xanthones, coumarins, phenolic acids, and others), and (iii) address the structure-activity relationship of phenolic compounds that lead to antimicrobial action.

Abstract
This study aimed to observe the effects of puerarin on glycolysis and cisplatin sensitivity in oral squamous cell carcinoma (oSCC) cells and to explore the underlying mechanisms. CAL27 cells over- or under-expressing FBXW7 were treated with cisplatin or puerarin, and the levels of proteins involved in glycolysis as well as the activity of the respective enzymes were assessed. Glucose uptake and lactate production were also evaluated, and the IC50 value of cisplatin in CAL27 cells was determined. FBXW7 overexpression significantly downregulated HK2, PKM2, and LDH; suppressed the activity of the corresponding enzymes hexokinase, pyruvate kinase, and lactate dehydrogenase; as well as reduced glucose uptake and lactate production. FBXW7 overexpression was also associated with decreased mTOR phosphorylation and increased cisplatin sensitivity. These effects were partially antagonized by lactate or the mTOR agonist MHY1485. Puerarin suppressed glycolysis by reducing glucose uptake and lactate production, while it promoted cisplatin sensitivity and activated the FBXW7/mTOR signal pathway in a concentration-dependent manner. These effects were antagonized by FBXW7 downregulation or treatment with MHY1485. Our results suggest that FBXW7 improves cisplatin chemosensitivity and suppresses glycolysis in oSCC cells, indicating its promising potential as a target for puerarin to regulate the cisplatin sensitivity of oSCC cells.

Abstract
Gastric cancer (GC) is among the five most common malignancies worldwide. Traditional chemotherapy cannot efficiently treat the disease and faces the problems of side effects and chemoresistance. Polygoni orientalis Fructus (POF), with flavonoids as the main bioactive compounds, exerts anti-cancer potential. In this study, we compared the anti-GC effects of the main flavonoids from POF and investigated the anti-cancer effects of eriodictyol towards GC both in vitro and in vivo. CCK-8 assays were performed to examine the inhibitory effects of common flavonoids from POF on GC cell viability. Colony formation assays were used to determine cell proliferation after eriodictyol treatment. Cell cycle distribution was analyzed using flow cytometry. Induction of apoptosis was assessed with Annexin V/PI staining and measurement of related proteins. Anti-cancer effects in vivo were investigated using a xenograft mouse model. Potential targets of eriodictyol were clarified by network pharmacological analysis, evaluated by molecular docking, and validated with Western blotting. We found that eriodictyol exhibited the most effective inhibitory effect on cell viability of GC cells among the common flavonoids from POF including quercetin, taxifolin, and kaempferol. Eriodictyol suppressed colony formation of GC cells and induced cell apoptosis. The inhibitory effects of eriodictyol on tumor growth were also validated using a xenograft mouse model. Moreover, no obvious toxicity was identified with eriodictyol treatment. Network pharmacology analysis revealed that PI3K/AKT signaling ranked first among the anti-GC targets. The molecular docking model of eriodictyol and PI3K was constructed, and the binding energy was evaluated. Furthermore, efficient inhibition of phosphorylation and activation of PI3K/AKT by eriodictyol was validated in GC cells. Taken together, our results identify eriodictyol as the most effective anti-GC flavonoids from POF and the potential targets of eriodictyol in GC. These findings suggest that eriodictyol has the potential to be a natural source of anti-GC agents.
