The Role of the Aryl Hydrocarbon Receptor (AhR) and Its Ligands in Breast Cancer. Cancers (Basel) 2022; 14:cancers14225574. [PMID: 36428667 PMCID: PMC9688153 DOI: 10.3390/cancers14225574] [Citation(s) in RCA: 24] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 10/27/2022] [Accepted: 11/11/2022] [Indexed: 11/16/2022] Open
Abstract
Breast cancer is a complex disease which is defined by numerous cellular and molecular markers that can be used to develop more targeted and successful therapies. The aryl hydrocarbon receptor (AhR) is overexpressed in many breast tumor sub-types, including estrogen receptor -positive (ER+) tumors; however, the prognostic value of the AhR for breast cancer patient survival is not consistent between studies. Moreover, the functional role of the AhR in various breast cancer cell lines is also variable and exhibits both tumor promoter- and tumor suppressor- like activity and the AhR is expressed in both ER-positive and ER-negative cells/tumors. There is strong evidence demonstrating inhibitory AhR-Rα crosstalk where various AhR ligands induce ER degradation. It has also been reported that different structural classes of AhR ligands, including halogenated aromatics, polynuclear aromatics, synthetic drugs and other pharmaceuticals, health promoting phytochemical-derived natural products and endogenous AhR-active compounds inhibit one or more of breast cancer cell proliferation, survival, migration/invasion, and metastasis. AhR-dependent mechanisms for the inhibition of breast cancer by AhR agonists are variable and include the downregulation of multiple genes/gene products such as CXCR4, MMPs, CXCL12, SOX4 and the modulation of microRNA levels. Some AhR ligands, such as aminoflavone, have been investigated in clinical trials for their anticancer activity against breast cancer. In contrast, several publications have reported that AhR agonists and antagonists enhance and inhibit mammary carcinogenesis, respectively, and differences between the anticancer activities of AhR agonists in breast cancer may be due in part to cell context and ligand structure. However, there are reports showing that the same AhR ligand in the same breast cancer cell line gives opposite results. These differences need to be resolved in order to further develop and take advantage of promising agents that inhibit mammary carcinogenesis by targeting the AhR.

Abstract
A novel low molecular mass ginkgo biloba trypsin inhibitor (GBTI) was isolated from ginkgo fruits (GF) by trypsin inhibitory activity-guided fractionation by using ammonium sulphate precipitation, followed by ultra-filtration, affinity chromatography and RP-HPLC. The molecular mass and amino acid sequence of GBTI was determined using ESI-MS and ESI-MS/MS, respectively. The structure of GBTI was identified as MKNLTVIPPICLKFPN, with a molecular mass of 1826 Da. GBTI was stable in the pH range of 4-8 and in the temperature range of 0-80 °C for 30 min. However, the inhibitory activity of the GBTI reduced when incubated with various metalions (K+, Na+, Fe2+, Mg2+ and Ca2+) . Finally, GBTI exhibited significant antiproliferative effect in human MDA-MB-231 and mouse 4 T-1 triple-negative breast cancer cells and without toxicity to MCF-10A normal breast cells. Our results suggest that GBTI could be exploited as a natural and hyperstable anticancer agent for triple-negative breast cancer patients.

Abstract
Four flavonoid glycosides containing coumaroyl or feruloyl groups were isolated from the male flowers of Ginkgo biloba L., and compounds 3 and 4 were identified as novel compounds. The inhibitory activities against α-glucosidase were investigated by docking studies, in vitro assays and kinetic studies. The docking results showed that all compounds mainly formed hydrogen-bond and π-π-stacking interactions with α-glucosidase. Compound 4 had the lowest binding energy and maximum number of hydrogen bonds. Subsequently, the in vitro assays showed that compound 4 exhibited the strongest inhibitory potency. Finally, the kinetic studies indicated the inhibitory mode of compounds 1-4 against α-glucosidase were mixed types of competitive and non-competitive. Together, these findings suggested that the isolated flavonoid glycosides in this study, especially compound 4, have potential as α-glucosidase inhibitors.

PLANTS (BASEL, SWITZERLAND) 2021; 10:1389. [PMID: 34371592 PMCID: PMC8309210 DOI: 10.3390/plants10071389] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 06/27/2021] [Accepted: 06/30/2021] [Indexed: 01/11/2023]
Abstract
Cissus incisa leaves have been traditionally used in Mexican traditional medicine to treat certain cancerous illness. This study explored the metabolomic profile of this species using untargeted technique. Likewise, it determined the cytotoxic activity and interpreted all data by computational tools. The metabolomic profile was developed through UHPLC-QTOF-MS/MS for dereplication purposes. MetaboAnalyst database was used in metabolic pathway analysis and the network topological analysis. Hexane, chloroform/methanol, and aqueous extracts were evaluated on HepG2, Hep3B, HeLa, PC3, A549, and MCF7 cancer cell lines and IHH immortalized hepatic cells, using Cell Titer proliferation assay kit. Hexane extract was the most active against Hep3B (IC50 = 27 ± 3 μg/mL), while CHCl3/MeOH extract was the most selective (SI = 2.77) on the same cell line. A Principal Component Analysis (PCA) showed similar profiles between the extracts, while a Venn diagram revealed 80 coincident metabolites between the bioactive extracts. The sesquiterpenoid and triterpenoid biosynthesis pathway was the most significant identified. The Network Pharmacology (NP) approach revealed several targets for presqualene diphosphate, phytol, stearic acid, δ-tocopherol, ursolic acid and γ-linolenic acid, involved in cellular processes such as apoptosis. This work highlights the integration of untargeted metabolomic profile and cytotoxic activity to explore plant extracts, and the NP approach to interpreting the experimental results.

Anti-migration and anti-invasion effects of 2-hydroxy-6-tridecylbenzoic acid is associated with the enhancement of CYP1B1 expression through activating the AMPK signaling pathway in triple-negative breast cancer cells.

Abstract
2-hydroxy-6-tridecylbenzoic acid is alkylsalicylic acid monomer compound, abundantly existed in the ginkgo biloba extracts, however, the underlying mechanism of its anti-migration and anti-invasion effects in triple-negative breast cancer (TNBC) is not clear. Here, 2-hydroxy-6 -tridecylbenzoic acid inhibited MDA-MB-231 and 4 T-1 cells growth without toxicity to MCF-10A normal breast cells. Meanwhile, 2-hydroxy-6-tridecylbenzoic acid inhibited cells migration and invasion as well as EMT with the increase of E-cadherin expression accompanied by the decrease of N-cadherin, Vimentin, Snail, MMP-2 and MMP-9 expression. The inhibition was further demonstrated by the enhancement of cytochrome P450 (CYP) 1B1 expression through the activation of AMP activated protein kinase (AMPK) in MDA-MB-231 and 4 T-1 cells. Silencing of CYP1B1 and AMPK with siRNA blocked the inhibitory effects of migration and invasion, and reversed the EMT related genes. These findings may provide a novel mechanism of the 2-hydroxy-6-tridecylbenzoic acid as a molecular-targeted therapeutic drug for TNBC patients.
