Abstract
Flavonoids are a highly abundant class of secondary metabolites present in plants. Isoflavonoids, in particular, are primarily synthesized in leguminous plants within the subfamily Papilionoideae. Numerous reports have established the favorable role of isoflavonoids in preventing a range of human diseases. Among the isoflavonoid components, glyceollins are synthesized specifically in soybean plants and have displayed promising effects in mitigating the occurrence and progression of breast and ovarian cancers as well as other diseases. Consequently, glyceollins have become a sought-after natural component for promoting women's health. In recent years, extensive research has focused on investigating the molecular mechanism underlying the preventative properties of glyceollins against various diseases. Substantial progress has also been made toward elucidating the biosynthetic pathway of glyceollins and exploring potential regulatory factors. Herein, we provide a review of the research conducted on glyceollins since their discovery five decades ago (1972-2023). We summarize their pharmacological effects, biosynthetic pathways, and advancements in chemical synthesis to enhance our understanding of the molecular mechanisms of their function and the genes involved in their biosynthetic pathway. Such knowledge may facilitate improved glyceollin synthesis and the creation of health products based on glyceollins.

Nutrients 2023; 15:nu15071632. [PMID: 37049472 PMCID: PMC10097176 DOI: 10.3390/nu15071632] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Revised: 03/21/2023] [Accepted: 03/24/2023] [Indexed: 03/30/2023] Open
Abstract
As breast cancer cells transition from letrozole-sensitive to letrozole-resistant, they over-express epidermal growth factor receptor (EGFR), mitogen-activated protein kinase (MAPK), and human epidermal growth factor receptor 2 (HER2) while acquiring enhanced motility and epithelial-to-mesenchymal transition (EMT)-like characteristics that are attenuated and reversed by glyceollin treatment, respectively. Interestingly, glyceollin inhibits the proliferation and tumor progression of triple-negative breast cancer (TNBC) and estrogen-independent breast cancer cells; however, it is unlikely that a single phytochemical would effectively target aromatase-inhibitor (AI)-resistant metastatic breast cancer in the clinical setting. Since our previous report indicated that the combination of lapatinib and glyceollin induced apoptosis in hormone-dependent AI-resistant breast cancer cells, we hypothesized that combination therapy would also be beneficial for hormone independent letrozole-resistant breast cancer cells (LTLT-Ca) compared to AI-sensitive breast cancer cells (AC-1) by decreasing the expression of proteins associated with proliferation and cell cycle progression. While glyceollin + lapatinib treatment caused comparable inhibitory effects on the proliferation and migration in both cell lines, combination treatment selectively induced S and G2/M phase cell cycle arrest of the LTLT-Ca cells, which was mediated by decreased cyclin B1. This phenomenon may represent a unique opportunity to design novel combinatorial therapeutic approaches to target hormone-refractory breast tumors.

Abstract
The isoflavonoid derivatives, pterocarpans and coumestans, are explored for multiple clinical applications as osteo-regenerative, neuroprotective and anti-cancer agents. The use of plant-based systems to produce isoflavonoid derivatives is limited due to cost, scalability, and sustainability constraints. Microbial cell factories overcome these limitations in which model organisms such as Saccharomyces cerevisiae offer an efficient platform to produce isoflavonoids. Bioprospecting microbes and enzymes can provide an array of tools to enhance the production of these molecules. Other microbes that naturally produce isoflavonoids present a novel alternative as production chassis and as a source of novel enzymes. Enzyme bioprospecting allows the complete identification of the pterocarpans and coumestans biosynthetic pathway, and the selection of the best enzymes based on activity and docking parameters. These enzymes consolidate an improved biosynthetic pathway for microbial-based production systems. In this review, we report the state-of-the-art for the production of key pterocarpans and coumestans, describing the enzymes already identified and the current gaps. We report available databases and tools for microbial bioprospecting to select the best production chassis. We propose the use of a holistic and multidisciplinary bioprospecting approach as the first step to identify the biosynthetic gaps, select the best microbial chassis, and increase productivity. We propose the use of microalgal species as microbial cell factories to produce pterocarpans and coumestans. The application of bioprospecting tools provides an exciting field to produce plant compounds such as isoflavonoid derivatives, efficiently and sustainably.

The ELEANOR non-coding RNA expression contributes to cancer dormancy and predicts late recurrence of ER-positive breast cancer. Cancer Sci 2022; 113:2336-2351.

Abstract
The recurrence risk of estrogen receptor (ER)-positive breast cancer remains high for a long period of time, unlike the other types of cancer. The late recurrence reflects the ability of cancer cells to remain dormant through various events, including cancer stemness acquisition, but the detailed mechanism is unknown. ESR1 locus enhancing and activating non-coding RNAs (ELEANORS) are a cluster of nuclear non-coding RNAs originally identified in a recurrent breast cancer cell model. Although their functions as chromatin regulators in vitro are well characterized, their roles in vivo remain elusive. In this study, we evaluated the clinicopathological features of ELEANORS, using primary and corresponding metastatic breast cancer tissues. The ELEANOR expression was restricted to ER-positive cases and well-correlated with the ER and progesterone receptor expression levels, especially at the metastatic sites. ELEANORS were detected in both primary and metastatic tumors (32% and 29%, respectively), and frequently in postmenopausal cases. Interestingly, after surgery, patients with ELEANOR-positive primary tumors exhibited increased relapse rates after, but not within, 5 years. Multivariate analysis showed that ELEANORS are independent recurrence risk factor. Consistently, analyses with cell lines, mouse xenografts and patient tissues revealed that ELEANORS upregulate a breast cancer stemness gene, CD44, and maintain the cancer stem cell population, which may facilitate tumor dormancy. Our findings highlight a new role of nuclear long non-coding RNAs and their clinical potential as predictive biomarkers and therapeutic targets for late recurrence of ER-positive breast cancer.

Glyceollins Trigger Anti-Proliferative Effects in Hormone-Dependent Aromatase-Inhibitor-Resistant Breast Cancer Cells through the Induction of Apoptosis. Int J Mol Sci 2022; 23:2887. [PMID: 35270029 PMCID: PMC8911299 DOI: 10.3390/ijms23052887] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 03/01/2022] [Accepted: 03/03/2022] [Indexed: 11/16/2022] Open
Abstract
Aromatase inhibitors (AIs) are standard treatment for estrogen-dependent postmenopausal breast tumors; however, resistance develops leading to tumor relapse and metastasis. We previously demonstrated that glyceollin inhibits proliferation, survival, and migration of hormone-independent letrozole-resistant breast cancer. Since many AI-resistant tumors remain hormone-dependent, identifying distinctions between estrogen-receptor-positive (ER+) and ER-negative (ER-) AI-resistant tumor response to therapy is critical. We hypothesize that treating ER+ letrozole-resistant T47D breast cancer cells (T47DaromLR) with a combination of 10 μM glyceollin and 0.5 μM lapatinib (a dual EGFR/HER2 inhibitor) will decrease cell proliferation through induction of apoptosis. The T47DaromLR cells were found to overexpress HER2 and MAPK while maintaining aromatase and ER levels compared to their letrozole-sensitive (T47Darom) counterparts. In the absence of estrogen stimulation, glyceollin ± lapatinib had no effect on the proliferation of the T47Darom cells, while glyceollin treatment caused 46% reduction in the proliferation of T47DaromLR cells, which was further diminished when combined with lapatinib. While neither agent influenced cell migration, glyceollin and lapatinib reduced S and G2/M phase cell entry and exclusively induced apoptosis by 1.29-fold in the T47DaromLR cells. Taken together, these results suggest that glyceollins and lapatinib may have potential as a novel combination therapeutic approach for hormone-dependent, letrozole-resistant tumors.

Abstract
Apart from the physiological effects of glyceollins, information regarding their tissue distribution is scarce in the literature. Thus, the aim of this study is to clarify the distribution of glyceollins in rat organs. Glyceollins I and III were orally administered to Sprague-Dawley rats (1.0 mg/kg) with daidzein as control, and their accumulations in organs were investigated by liquid chromatography-time-of-flight/mass spectrometry (LC-TOF/MS). Glyceollins accumulated in intact and conjugated forms in circulatory organs with a Tmax of 0.5 h, in the following order of descending preference: liver, kidney, heart, lung, soleus muscle, and abdominal aorta. The accumulation of hydrophobic glyceollin I was more than 1.5 times higher than that of III. In contrast, daidzein and hydroxy equol were detected only in the liver and kidneys at lower concentrations (1/100 times) than those of glyceollins. In conclusion, prenylated isoflavones, glyceollins, were preferentially distributed in circulatory organs as intact, sulfated, or glucuronidated forms up to 6 h after the intake.

Abstract
Apart from the physiological functions of soybean phytoalexins, the production sites in soybeans remain unknown. In this study, the dynamic production of phytoalexins, glyceollins, in germinating soybeans inoculated with Aspergillus oryzae was visually investigated using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) imaging. During a 3-day sensitization using a fungus, glyceollins I-III were produced in germinating soybeans (from 0.03 mg/g for glyceollin III to 0.96 mg/g for glyceollin I). Imaging analysis provided visual evidence that glyceollins were produced only in the regions of seed coat and germinated root of the soybeans, while no production was observed in other regions, including the cotyledons. In contrast, their precursor, isoflavone, was distributed throughout the soybean. The evidence that the inoculation of the inactivated fungi also caused glyceollin production at the seed coat led us to speculate that glyceollins could be produced in the region of soybean attached to the fungus body.

Abstract
The valorization of agri-food by-products is essential from both economic and sustainability perspectives. The large quantity of such materials causes problems for the environment; however, they can also generate new valuable ingredients and products which promote beneficial effects on human health. It is estimated that soybean production, the major oilseed crop worldwide, will leave about 597 million metric tons of branches, leaves, pods, and roots on the ground post-harvesting in 2020/21. An alternative for the use of soy-related by-products arises from the several bioactive compounds found in this plant. Metabolomics studies have already identified isoflavonoids, saponins, and organic and fatty acids, among other metabolites, in all soy organs. The present review aims to show the application of metabolomics for identifying high-added-value compounds in underused parts of the soy plant, listing the main bioactive metabolites identified up to now, as well as the factors affecting their production.

Abstract
Although prenylated isoflavones or glyceollins elicit physiological effects more potent than those by isoflavones, the bioavailability remains unclear. The present study aimed to clarify the intestinal absorption behavior of glyceollins in Sprague-Dawley rats. Upon oral administration of 1.0 mg/kg glyceollin I or III (daidzein as comparative compound) to the rats, no peaks corresponding to the intact forms of the compounds were detected in plasma by liquid chromatography-time-of-flight/mass spectrometry (LC-TOF/MS) analysis. In contrast, enzymatic deconjugation of plasma resulted in successful MS detection of each glyceollin; glyceollin I absorption was >10 times higher than that of daidzein, given its high log P value. The present study demonstrated for the first time that glyceollins were more absorbable than mother isoflavones due to their high hydrophobicity, and they metabolized to form sulfated, glucuronized, and methylated conjugates during the intestinal absorption process.

Abstract
The eukaryotic nucleus is not a homogenous single‐spaced but a highly compartmentalized organelle, partitioned by various types of membraneless structures, including nucleoli, PML bodies, paraspeckles, DNA damage foci and RNA clouds. Over the past few decades, these nuclear structures have been implicated in biological reactions such as gene regulation and DNA damage response and repair, and are thought to provide “microenvironments,” facilitating these reactions in the nucleus. Notably, an altered morphology of these nuclear structures is found in many cancers, which may relate to so‐called “nuclear atypia” in histological examinations. While the diagnostic significance of nuclear atypia has been established, its nature has remained largely enigmatic and awaits characterization. Here, we review the emerging biophysical principles that govern biomolecular condensate assembly in the nucleus, namely, liquid‐liquid phase separation (LLPS), to investigate the nature of the nuclear microenvironment. In the nucleus, LLPS is typically driven by multivalent interactions between proteins with intrinsically disordered regions, and is also facilitated by protein interaction with nucleic acids, including nuclear non–coding RNAs. Importantly, an altered LLPS leads to dysregulation of nuclear events and epigenetics, and often to tumorigenesis and tumor progression. We further note the possibility that LLPS could represent a new therapeutic target for cancer intervention.

Long Noncoding RNAs Involved in the Endocrine Therapy Resistance of Breast Cancer. Cancers (Basel) 2020; 12:cancers12061424. [PMID: 32486413 PMCID: PMC7353012 DOI: 10.3390/cancers12061424] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 05/25/2020] [Accepted: 05/27/2020] [Indexed: 02/06/2023] Open
Abstract
Long noncoding RNAs (lncRNAs) are defined as RNAs longer than 200 nucleotides that do not encode proteins. Recent studies have demonstrated that numerous lncRNAs are expressed in humans and play key roles in the development of various types of cancers. Intriguingly, some lncRNAs have been demonstrated to be involved in endocrine therapy resistance for breast cancer through their own mechanisms, suggesting that lncRNAs could be promising new biomarkers and therapeutic targets of breast cancer. Here, we summarize the functions and mechanisms of lncRNAs related to the endocrine therapy resistance of breast cancer.

Abstract
Appropriate gene expression is essential for producing the correct amount of proteins at the right time, which is critical for living organisms. In the three-dimensional (3D) space of the nucleus, genomes are folded into higher order chromatin structures that are intimately associated with epigenetic factors, including histone modifications and nuclear long non-coding RNAs (lncRNAs). LncRNAs regulate transcription for both activation and repression, either in cis or in trans. Many ncRNAs are expressed in development-specific, differentiation-specific, and disease-specific manners, suggesting that they are critical regulators for organ generation and maintenance. In this review, we mainly describe the following ncRNAs: Xist, involved in X chromosome inactivation, Firre, which serves as a platform for trans-chromosomal associations, and UMLILO and ELEANORS, which co-regulate genes involved in the immune response and breast cancer, respectively. These ncRNAs are gene regulators in the context of the 3D genome structure.

Abstract
In the nucleus, genomic DNA is wrapped around histone octamers to form nucleosomes. In principle, nucleosomes are substantial barriers to transcriptional activities. Nuclear non-coding RNAs (ncRNAs) are proposed to function in chromatin conformation modulation and transcriptional regulation. However, it remains unclear how ncRNAs affect the nucleosome structure. Eleanors are clusters of ncRNAs that accumulate around the estrogen receptor-α (ESR1) gene locus in long-term estrogen deprivation (LTED) breast cancer cells, and markedly enhance the transcription of the ESR1 gene. Here we detected nucleosome depletion around the transcription site of Eleanor2, the most highly expressed Eleanor in the LTED cells. We found that the purified Eleanor2 RNA fragment drastically destabilized the nucleosome in vitro. This activity was also exerted by other ncRNAs, but not by poly(U) RNA or DNA. The RNA-mediated nucleosome destabilization may be a common feature among natural nuclear RNAs, and may function in transcription regulation in chromatin. The Eleanor cluster of non-coding RNAs is localised upstream of estrogen receptor-α (ESR1) gene locus in estrogen-deprived breast cancer cells. Fujita et al find that RNA fragments of Eleanor2 and of other non-coding RNAs are able to destabilise nucleosomes in vitro, suggesting a role in transcriptional regulation.

The Eleanor ncRNAs activate the topological domain of the ESR1 locus to balance against apoptosis. Nat Commun 2019; 10:3778.

Abstract
MCF7 cells acquire estrogen-independent proliferation after long-term estrogen deprivation (LTED), which recapitulates endocrine therapy resistance. LTED cells can become primed for apoptosis, but the underlying mechanism is largely unknown. We previously reported that Eleanor non-coding RNAs (ncRNAs) upregulate the ESR1 gene in LTED cells. Here, we show that Eleanors delineate the topologically associating domain (TAD) of the ESR1 locus in the active nuclear compartment of LTED cells. The TAD interacts with another transcriptionally active TAD, which is 42.9 Mb away from ESR1 and contains a gene encoding the apoptotic transcription factor FOXO3. Inhibition of a promoter-associated Eleanor suppresses all genes inside the Eleanor TAD and the long-range interaction between the two TADs, but keeps FOXO3 active to facilitate apoptosis in LTED cells. These data indicate a role of ncRNAs in chromatin domain regulation, which may underlie the apoptosis-prone nature of therapy-resistant breast cancer cells and could be good therapeutic targets. Long term estrogen deprivation can result in apoptosis in breast cancer cells. Here, the authors show that this apoptosis is induced by the long-range chromatin interaction of loci containing the ESR1 and FOXO3 genes, resulting in FOXO3-mediated apoptosis.

Abstract
Large-scale transcriptome analyses have identified a variety of non-coding RNAs (ncRNAs) that are not translated into proteins. Many of them are in the nucleus, where they associate with chromatin and regulate its structure and function. Interphase chromosomes are intricately folded into multiple layers and composed of domains. Recent studies using Hi-C technologies have identified a mega-base self-associating chromatin domain: the topologically associating domain (TAD). The domain boundaries are demarcated with the chromatin regulatory proteins CTCF and cohesin, which are often bound to or recruited by ncRNAs. Some ncRNAs form RNA clouds in the nucleus and coordinate the transcription of multiple genes in a chromatin domain. In this review, we describe the emerging link between long ncRNAs and chromatin domains in the nucleus.

Abstract
The role of phytochemicals as potential prodrugs or therapeutic substances against tumors has come in the spotlight in the very recent years, thanks to the huge mass of encouraging and promising results of the in vitro activity of many phenolic compounds from plant raw extracts against many cancer cell lines. Little but important evidence can be retrieved from the clinical and nutritional scientific literature, where flavonoids are investigated as major pro-apoptotic and anti-metastatic compounds. However, the actual role of these compounds in cancer is still far to be fully elucidated. Many of these phytochemicals act in a pleiotropic and poorly specific manner, but, more importantly, they are able to tune the reactive oxygen species (ROS) signaling to activate a survival or a pro-autophagic and pro-apoptosis mechanism, depending on the oxidative stress-responsive endowment of the targeted cell. This review will try to focus on this issue.
