Miao K, Zhao Y, Xue N. Gkongensin A, an HSP90β inhibitor, improves hyperlipidemia, hepatic steatosis, and insulin resistance. Heliyon 2024; 10:e29367. [PMID: 38655315 PMCID: PMC11036013 DOI: 10.1016/j.heliyon.2024.e29367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 03/29/2024] [Accepted: 04/07/2024] [Indexed: 04/26/2024] Open
Abstract
The prevalence of obesity and its primary associated comorbidities, such as type 2 diabetes and fatty liver disease, has reached epidemic proportions, with no successful treatment available at present. Heat shock protein 90 (HSP90), a crucial chaperone, plays a key role in de novo lipogenesis (DNL) by stabilizing and maintaining sterol regulatory element binding protein (SREBP) activity. Kongensin A (KA), derived from Croton kongensis, inhibits RIP3-mediated necrosis, showing promise as an anti-necrotic and anti-inflammatory agent. It is not yet clear if KA, acting as an HSP90 inhibitor, can enhance hyperlipidemia, hepatic steatosis, and insulin resistance in obese individuals by controlling lipid metabolism. In this study, we first found that KA can potentially decrease lipid content at the cellular level. C57BL/6J mice were given a high-fat diet (HFD) and received KA and lovastatin through oral administration for 7 weeks. KA improved hyperlipidemia, fatty liver, and insulin resistance, as well as reduced body weight in diet-induced obese (DIO) mice, with no significant alteration in food intake. In vitro, KA suppressed DNL and reduced the amounts of mSREBPs. KA promoted mSREBP degradation via the FBW7-mediated ubiquitin-proteasome pathway. KA decreased the level of p-Akt Ser308, and p-GSK3β Ser9 by inhibiting the interaction between HSP90β and Akt. Overall, KA enhanced hyperlipidemia, hepatic steatosis, and insulin resistance by blocking SREBP activity, thereby impacting the FBW7-controlled ubiquitin-proteasome pathway.

Hua X, Ge S, Zhang L, Jiang Q, Chen J, Xiao H, Liang C. MED15 is upregulated by HIF-2α and promotes proliferation and metastasis in clear cell renal cell carcinoma via activation of SREBP-dependent fatty acid synthesis. Cell Death Discov 2024; 10:188. [PMID: 38649345 PMCID: PMC11035615 DOI: 10.1038/s41420-024-01944-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 03/26/2024] [Accepted: 04/04/2024] [Indexed: 04/25/2024] Open
Abstract
Emerging evidence has highlighted that dysregulation of lipid metabolism in clear cell renal cell carcinoma (ccRCC) is associated with tumor development and progression. HIF-2α plays an oncogenic role in ccRCC and is involved in abnormal lipid accumulation. However, the underlying mechanisms between these two phenomena remain unknown. Here, MED15 was demonstrated to be a dominant factor for HIF-2α-dependent lipid accumulation and tumor progression. HIF-2α promoted MED15 transcriptional activation by directly binding the MED15 promoter region, and MED15 overexpression significantly alleviated the lipid deposition inhibition and malignant tumor behavior phenotypes induced by HIF-2α knockdown. MED15 was upregulated in ccRCC and predicted poor prognosis. MED15 promoted lipid deposition and tumor progression in ccRCC. Mechanistic investigations demonstrated that MED15 acts as SREBP coactivator directly interacting with SREBPs to promote SREBP-dependent lipid biosynthesis enzyme expression, and promotes SREBP1 and SREBP2 activation through the PLK1/AKT axis. Overall, we describe a molecular regulatory network that links MED15 to lipid metabolism induced by the SREBP pathway and the classic HIF-2α pathway in ccRCC. Efforts to target MED15 or inhibit MED15 binding to SREBPs as a novel therapeutic strategy for ccRCC may be warranted.

Abstract
In the current study, we investigated the insecticidal efficacy of two borates, disodium octaborate tetrahydrate (Etidot-67) and calcium metaborate (CMB) via surface application or diet delivery on the red flour beetle, Tribolium castaneum (Herbst, 1797) (Coleoptera: Tenebrionidae). The application method did not change the boron-related mortality, but CMB was more effective than Etidot-67. At the highest dose, it took around 13 days to reach the highest mortality (≥98.1%) for CMB, while it was 19 days for Etidot-67 (≥95.8%). Both boron compounds led to a significant reduction in triglyceride levels in parallel to the downregulation of acetyl-CoA carboxylase (ACC) and fatty acid synthase (FAS), the two primary genes involved in de novo lipogenesis, while they also induced body weight loss. In conclusion, the current study indicated the insecticidal potential of boron compounds but CMB is more promising and more effective in controlling T. castaneum, while lipogenesis is inhibited and weight loss is induced by boron compounds.

Abstract
Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly defined as non-alcoholic fatty liver disease (NAFLD), is a disorder marked by the excessive deposition of lipids in the liver, giving rise to a spectrum of liver pathologies encompassing steatohepatitis, fibrosis/cirrhosis, and hepatocellular carcinoma. Despite the alarming increase in its prevalence, the US Food and Drug Administration has yet to approve effective pharmacological therapeutics for clinical use. MASLD is characterized by the accretion of lipids within the hepatic system, arising from a disarray in lipid provision (whether through the absorption of circulating lipids or de novo lipogenesis) and lipid elimination (via free fatty acid oxidation or the secretion of triglyceride-rich lipoproteins). This disarray leads to the accumulation of lipotoxic substances, cellular pressure, damage, and fibrosis. Indeed, the regulation of the lipid metabolism pathway is intricate and multifaceted, involving a myriad of factors, such as membrane transport proteins, metabolic enzymes, and transcription factors. Here, we will review the existing literature on the key process of lipid metabolism in MASLD to understand the latest progress in this molecular mechanism. Notably, de novo lipogenesis and the roles of its two main transcription factors and other key metabolic enzymes are highlighted. Furthermore, we will delve into the realm of drug research, examining the recent progress made in understanding lipid metabolism in MASLD. Additionally, we will outline prospective avenues for future drug research on MASLD based on our unique perspectives.

Abstract
INTRODUCTION Sterol regulatory element-binding proteins (SREBPs) are a family of membrane-binding transcription factors that activate genes encoding enzymes required for cholesterol and unsaturated fatty acid synthesis. Overactivation of SREBP is related to the occurrence and development of diabetes, nonalcoholic fatty liver, tumor, and other diseases. In the past period, many SREBP inhibitors have been found. AREAS COVERED This manuscript is a patent review of SREBP inhibitors. We searched 2008 to date for all data from the US patent database (https://www.uspto.gov/) and the European patent database (https://www.epo.org/) with 'SREBP' and 'inhibitor' as keywords and analyzed the search results. EXPERT OPINION Both synthetic and natural SREBP inhibitors have been reported. Despite the lack of cocrystal structure of SREBP inhibitor, the mechanisms of several compounds have been clarified. Importantly, some SREBP inhibitors have been proved to have good activity in preclinical studies. As the characteristics of lipid metabolism reprogramming in cardio-cerebrovascular diseases and tumors are gradually revealed, more and more attention will be focused on SREBP.

Abstract
Lipids are essential metabolites, which function as energy sources, structural components and signalling mediators. Most cells are able to convert carbohydrates into fatty acids, which are often converted into neutral lipids for storage in the form of lipid droplets. Accumulating evidence suggests that lipogenesis plays a crucial role not only in metabolic tissues for systemic energy homoeostasis but also in immune and nervous systems for their proliferation, differentiation and even pathophysiological roles. Thus, excessive or insufficient lipogenesis is closely associated with aberrations in lipid homoeostasis, potentially leading to pathological consequences, such as dyslipidaemia, diabetes, fatty liver, autoimmune diseases, neurodegenerative diseases and cancers. For systemic energy homoeostasis, multiple enzymes involved in lipogenesis are tightly controlled by transcriptional and post-translational modifications. In this Review, we discuss recent findings regarding the regulatory mechanisms, physiological roles and pathological importance of lipogenesis in multiple tissues such as adipose tissue and the liver, as well as the immune and nervous systems. Furthermore, we briefly introduce the therapeutic implications of lipogenesis modulation.

Abstract
The application of natural and synthetic boron-containing compounds (BCC) in biomedical field is expanding. BCC have effects in the metabolism of living organisms. Some boron-enriched supplements are marketed as they exert effects in the bone and skeletal muscle; but also, BCC are being reported as acting on the enzymes and transporters of membrane suggesting they could modify the carbohydrate metabolism linked to some pathologies of high global burden, as an example is diabetes mellitus. Also, some recent findings are showing effects of BCC on lipid metabolism. In this review, information regarding the effects and interaction of these compounds was compiled, as well as the potential application for treating human metabolic disorders is suggested.

Abstract
Non‑alcoholic fatty liver disease (NAFLD) is an increasingly prevalent ailment worldwide. Moreover, de novo lipogenesis (DNL) is considered a critical factor in the development of NAFLD; hence, its inhibition is a promising target for the prevention of fatty liver disease. There is evidence to indicate that AMP‑activated protein kinase (AMPK) and sirtuin 1 (SIRT1) may play a crucial role in DNL and are the regulatory proteins in type 2 diabetes mellitus, obesity and cardiovascular disease. Therefore, AMPK and SIRT1 may be promising targets for the treatment of NAFLD. The present review article thus aimed to summarize the findings of clinical studies published during the past decade that suggested the beneficial effects of AMPK and SIRT1, using their specific activators and their combined effects on fatty liver disease.

Abstract
Eye size is a key parameter of visual function, but the precise mechanisms of eye size control remain poorly understood. Here, we discovered that the lipogenic transcription factor sterol regulatory element-binding protein 2 (SREBP2) has an unanticipated function in the retinal pigment epithelium (RPE) to promote eye size in postnatal mice. SREBP2 transcriptionally represses low density lipoprotein receptor-related protein 2 (Lrp2), which has been shown to restrict eye overgrowth. Bone morphogenetic protein 2 (BMP2) is the downstream effector of Srebp2 and Lrp2, and Bmp2 is suppressed by SREBP2 transcriptionally but activated by Lrp2. During postnatal development, SREBP2 protein expression in the RPE decreases whereas that of Lrp2 and Bmp2 increases as the eye growth rate reduces. Bmp2 is the key determinant of eye size such that its level in mouse RPE inversely correlates with eye size. Notably, RPE-specific Bmp2 overexpression by adeno-associated virus effectively prevents the phenotypes caused by Lrp2 knock out. Together, our study shows that rapid postnatal eye size increase is governed by an RPE-derived signaling pathway, which consists of both positive and negative regulators of eye growth.

Abstract
BACKGROUND The worldwide growing trend of obesity across all ages has increased the number of researches on the obesity management and prevention. Boron is a potential essential trace element and there are some promising results on its weight lowering effect. Therefore, the present meta-analysis was aimed to assess the effect of boron on body weight. METHOD Databases including PubMed, Scopus, Cochrane Library, Embase, and Google Scholar were searched from 1995 until November 2021 using the definitive keywords. Searching was limited to articles with English language. Human studies were excluded in our analyses regarding their limited number and the heterogeneity of study designs. All of the relevant animal studies on rodents with weight changes as a primary outcome were included. The assessments of risk of bias and heterogeneity were conducted using the Cochrane Risk of Bias tool and I-square (I2) statistic respectively. RESULTS According to our findings the overall effect of boron administration orally was significant decrease of body weight (WMD = -18.12 g 95% CI -23.28, -12.96; P < 0.001). The boron compound administration was more effective in the borax form and also when the intervention duration was ≤ 4 weeks. Moreover, the effect size was greater in the male gender rather than female animals. CONCLUSION Most of the experimental studies supported the weight lowering effect of boron although, there are a few inconsistent evidences. It seems that the weight lowering effect of boron may be through increasing the energy metabolism, thermogenesis, lipolysis and inhibition of adiposeness. However, future clinical trials can better clarify the effects of boron on obesity management.

Abstract
A standard goal of medicinal chemists has been to discover efficient and potent drug candidates with specific enzyme-inhibitor abilities. In this regard, boron-based bioactive compounds have provided amphiphilic properties to facilitate interaction with protein targets. Indeed, the spectrum of boron-based entities as drug candidates against many diseases has grown tremendously since the first clinically tested boron-based drug, Velcade. In this review, we collectively represent the current boron-containing drug candidates, boron-containing retinoids, benzoxaboroles, aminoboronic acid, carboranes, and BODIPY, for the treatment of different human diseases.In addition, we also describe the synthesis, key structure-activity relationship, and associated biological activities, such as antimicrobial, antituberculosis, antitumor, antiparasitic, antiprotozoal, anti-inflammatory, antifolate, antidepressant, antiallergic, anesthetic, and anti-Alzheimer's agents, as well as proteasome and lipogenic inhibitors. This compilation could be very useful in the exploration of novel boron-derived compounds against different diseases, with promising efficacy and lesser side effects.

Sodium Pentaborate Pentahydrate ameliorates lipid accumulation and pathological damage caused by high fat diet induced obesity in BALB/c mice. J Trace Elem Med Biol 2021; 66:126736. [PMID: 33711700 DOI: 10.1016/j.jtemb.2021.126736] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Revised: 02/23/2021] [Accepted: 03/02/2021] [Indexed: 12/21/2022]
Abstract
BACKGROUND Obesity is one of the most popular topic in the field of research. In order to defeat this highly widespread disease, the mechanism of fat accumulation at the molecular level and its elimination are crucial. The use of boron has been showing promising results during the recent years. METHODS In this study, anti-obesity potential of Sodium Pentaborate Pentahydrate (SPP) used as a dietary supplement on BALB/c mice fed with a high-fat diet was evaluated. Mice were divided into four groups with different diets, consisting of a normal diet, a high-fat diet (HFD) (containing 60 % fat), a HFD-supplemented with 0.5 mg/g body weight (BW) of SPP and a HFD-supplemented with 1.5 mg/g body weight (BW) of SPP. The animals were then observed for 10 weeks and physically monitored, and were sacrificed at the end of the experiment for physical and physicochemical evaluation. RESULTS According to the physical parameters measured -body weight, food and water intake ratios-, the results indicate that SPP decreased weight gain in a dose dependent manner. Measurement of the hormone levels in the blood and fat accumulation in organs of mice also supported the anti-obesity effects of SPP. Expressions of adipogenesis related genes were also negatively regulated by SPP administration in white adipose tissue (WAT) tissue. CONCLUSION These findings promise a treatment approach and drug development that can be used against obesity when SPP is used in the right doses. As a future aspect, clinical studies with SPP will reveal the effect of boron derivatives on obesity.

Eur J Pharmacol 2021; 906:174280. [PMID: 34174265 DOI: 10.1016/j.ejphar.2021.174280] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 06/18/2021] [Accepted: 06/22/2021] [Indexed: 12/25/2022]
Abstract
Hepatocellular carcinoma (HCC) is the major type of primary liver cancer and a leading cause of cancer-related deaths worldwide. Cinobufotalin (CBF) is extracted from the skin secretion of the giant toad and clinically used for the treatment of liver cancer, but its molecular mechanism of anti-cancer in HCC has not yet been elucidated. Here, we showed CBF effectively promoted cell apoptosis, induced cell cycle G2-M arrest, inhibited cell proliferation and lipogenesis. Consistently, the lipogenesis ability of xenograft examined by 11C-acetate micro-PET/CT imaging, and the tumor growth rate was notably declined in a centration-dependent manner. The fatty acid profiles showed saturated and mono-unsaturated fatty acid significantly decreased after CBF treatment. Mechanistically, CBF selectively inhibited the expression of SREBP1 and interacted with SREBP1 to prevent it from sterol regulatory elements (SREs), thus inhibiting the expression of lipogenic enzymes. Collectively, our study demonstrates that CBF is a potent native compound that remarkably inhibits HCC lipogenesis and tumorigenesis. CBF may possess this therapeutic potential though interfering with de novo lipid synthesis via SREBP1.

Abstract
Turmeric, the rhizome of Curcuma longa plant belonging to the ginger family Zingiberaceae, has a history in Ayurvedic and traditional Chinese medicine for treatment of chronic diseases, including metabolic and cardiovascular diseases (CVD). This parallels a prevalence of age- and lifestyle-related diseases, especially CVD and type 2 diabetes (T2D), and associated mortality which has occurred in recent decades. While the chemical composition of turmeric is complex, curcuminoids and essential oils are known as two major groups that display bioactive properties. Curcumin, the most predominant curcuminoid, can modulate several cell signaling pathways involved in the etiology and pathogenesis of CVD, T2D, and related morbidities. Lesser bioactivities have been reported from other curcuminoids and essential oils. This review examines the chemical compositions of turmeric, and related bioactive constituents. A focus was placed on the cellular and molecular mechanisms that underlie the protective effects of turmeric and turmeric-derived compounds against diabetes and CVD, compiled from the findings obtained with cell-based and animal models. Evidence from clinical trials is also presented to identify potential preventative and therapeutic efficacies. Clinical studies with longer intervention durations and specific endpoints for assessing health outcomes are warranted in order to fully evaluate the long-term protective efficacy of turmeric.

Abstract
Elevated lipogenesis is an important metabolic hallmark of rapidly proliferating tumor such as endometrial carcinoma (EC). The sterol regulatory element-binding protein 1 (SREBP1) is a master regulator of lipogenesis and involved in EC proliferation. BF175 is a novel chemical inhibitor of SREBP pathway, and has shown potent anti-lipogenic effects. However, the effect of BF175 on EC cells are yet to be determined. In the present study, we found that BF175 decreased cell viability, colony formation and migratory capacity, inducing autophagy and mitochondrial related apoptosis in EC cell line AN3CA. Z-VAD-FMK partially attenuated the effect of BF175 on AN3CA. In addition, BF175 significantly downregulated SREBPs and their downstream genes. The levels of free fatty acids and total cholesterol were also inhibited. Microarray analysis suggested BF175 treatment obviously affected lipid metabolic pathways in EC. Taken together, we validated BF175 exhibited anti-tumor activity by targeting SREBP-dependent lipogenesis and inducing apoptosis which mitochondrial pathway involved in, suggesting that it's potential as a novel therapeutic reagent for EC.

J Trace Elem Med Biol 2020; 62:126573.

Abstract
BACKGROUND Boron is a prominent part of the human diet and one of the essential trace elements for humans. Dietary boron is mostly transformed into boric acid within the body and has been associated with desirable health outcomes. Non-dietary resources of boron, such as boron-based drugs and occupational exposure, might lead to excessive boron levels in the blood and provoke health adversities. The liver might be particularly sensitive to boron intake with ample evidence suggesting a relation between boron and liver function, although the underlying molecular processes remain largely unknown. METHODS In order to better understand boron-related metabolism and molecular mechanisms associated with a cytotoxic level of boric acid, the half-maximal inhibitory concentration (IC50) of boric acid for the hepatoma cell line (HepG2) was determined using the XTT assay. Cellular responses followed by boric acid treatment at this concentration were investigated using genotoxicity assays and microarray hybridizations. Enrichment analyses were carried out to find out over-represented biological processes using the list of differentially expressed genes identified within the gene expression analysis. RESULTS DNA breaks were detected in HepG2 cells treated with 24 mM boric acid, the estimated IC50-level of boric acid. On the other hand, pleiotropic transcriptomic effects, including cell cycle arrest, DNA repair, and apoptosis as well as altered expression of Phase I and Phase II enzymes, amino acid metabolism, and lipid metabolism were discerned in microarray analyses. CONCLUSION HepG2 cells treated with a growth-inhibitory concentration of boric acid for 24 h exhibited a senescence-like transcriptomic profile along with DNA damage. Further studies might help in understanding the concentration-dependent effects and mechanisms of boric acid.

Abstract
Obesity has become a recognized global epidemic that is associated with numerous comorbidities including type II diabetes, cardiovascular disease, hypertension, and cancer incidence and progression. Ovarian cancer (OvCa) has a unique mechanism of intra-peritoneal metastasis, already present in 80% of women at the time of diagnosis, making it the fifth leading cause of death from gynecological malignancy. Meta-analyses showed that obesity increases the risk of OvCa progression, leads to enhanced overall and organ-specific tumor burden, and adversely effects survival of women with OvCa. Recent data discovered that tumors grown in mice fed on a western diet (40% fat) have elevated lipid levels and a highly increased expression level of sterol regulatory element binding protein 1 (SREBP1). SREBP1 is a master transcription factor that regulates de novo lipogenesis and lipid homeostasis, and induces lipogenic reprogramming of tumor cells. Elevated SREBP1 levels are linked to cancer cell proliferation and metastasis. This review will summarize recent findings to provide a current understanding of lipid regulatory proteins in the ovarian tumor microenvironment with emphasis on SREBP1 expression in the obese host, the role of SREBP1 in cancer progression and metastasis, and potential therapeutic targeting of SREBPs and SREBP-pathway genes in treating cancers, particularly in the context of host obesity.

Abstract
Obesity, associated with a series of complications such as diabetes, hypertension, and
heart disease, is a great threat to human health and leads to increased morbidity and mortality. Despite
the presence of anti-obesity agents on the market, the application of these drugs is limited because
of their typical side effects. More effective and safe weight-loss drugs are being pursued by
many researchers, correspondingly, growing small molecules and natural products with anti-obesity
effects have been identified and the molecular mechanisms underlying the action of the novel and
known compounds have at least partially been revealed. Therefore, the field does witness great progress
year by year. In this review, we intend to provide a comprehensive and updated view on the
known and novel compounds which possess anti-obesity effects and further classify them according
to the molecular mechanisms of their actions in regulating the major anti-obesity pathways.

Abstract
As the most important bioactive substance in Garcinia cambogia, (-)-hydroxycitric acid (HCA) is widely used in food additives to regulate obesity and diabetes in animals or humans, while the mechanism is poorly understood. The purpose of this study was to elucidate the regulatory effect and mechanism of (-)-HCA in regulating glucose and lipid metabolism in chicken primary hepatocytes. The results showed that (-)-HCA obviously decreased triglyceride content through inhibiting the fatty acid synthase protein level, and enhancing the protein level of phosphorylated acetyl CoA carboxylase, enoyl coenzyme A hydratase short chain 1 and carnitine palmitoyltransferase 1A in hepatocytes. Moreover, (-)-HCA markedly enhanced the protein level of phosphofructokinase-1, pyruvate dehydrogenase, succinate dehydrogenase A and complex IV, and which led to the enhancing of glucose uptake and catabolism in hepatocytes. Importantly, the regulation of (-)-HCA on these key factors associated with lipid and glucose metabolism in hepatocytes was mainly achieved through activation of AMP-activated protein kinase/peroxisome proliferator-activated receptor gamma coactivator 1α-nuclear respiratory factor 1 signaling pathway. These results convincingly demonstrated the mechanism of (-)-HCA's regulating on glucose and lipid metabolism, and provided a strategy in prevention of diseases associated with glycolipid metabolic abnormalities in animals, even in humans.

[PMID: 32168434 PMCID: PMC7176863 DOI: 10.1111/jcmm.15141] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Revised: 02/05/2020] [Accepted: 02/19/2020] [Indexed: 12/24/2022] Open
Abstract
The non-POU domain-containing octamer-binding protein NONO/p54nrb , which belongs to the Drosophila behaviour/human splicing (DBHS) family, is a multifunctional nuclear protein rarely functioning alone. Emerging solid evidences showed that NONO engages in almost every step of gene regulation, including but not limited to mRNA splicing, DNA unwinding, transcriptional regulation, nuclear retention of defective RNA and DNA repair. NONO is involved in many biological processes including cell proliferation, apoptosis, migration and DNA damage repair. Dysregulation of NONO has been found in many types of cancer. In this review, we summarize the current and fast-growing knowledge about the regulation of NONO, its biological function and implications in tumorigenesis and cancer progression. Overall, significant findings about the roles of NONO have been made, which might make NONO to be a new biomarker or/and a possible therapeutic target for cancers.

Abstract
Rosmarinus species are aromatic plants that mainly grow in the Mediterranean region. They are widely used in folk medicine, food, and flavor industries and represent a valuable source of biologically active compounds (e.g., terpenoids, flavonoids, and phenolic acids). The extraction of rosemary essential oil is being done using three main methods: carbon dioxide supercritical extraction, steam distillation, and hydrodistillation. Furthermore, interesting antioxidant, antibacterial, antifungal, antileishmanial, anthelmintic, anticancer, anti-inflammatory, antidepressant, and antiamnesic effects have also been broadly recognized for rosemary plant extracts. Thus the present review summarized data on economically important Rosmarinus officinalis species, including isolation, extraction techniques, chemical composition, pharmaceutical, and food applications.

Abstract
BACKGROUND Boron is an element commonly found in nature. The main boron source for organisms is through food and drinking water. In recent years, it is suggested that the "boron-rich diet" can affect human health positively. However, more detailed studies are needed. OBJECTIVE The aim of this study was to examine the effect of increased dietary boron intake on some biochemical parameters in humans. MATERIAL AND METHODS Thirteen healthy women consumed diets containing 10 mg more boron than their routine diet for one month. This boron intake was provided with the increase of boron-rich foods such as dried fruits, avocado, and nuts in the diet. Some biochemical and hematologic parameters were determined in blood, urine and saliva samples taken before and after a boron-rich diet. RESULTS Serum, salivary, and urine boron concentrations increased 1.3, 1.7, 6.0 fold, respectively. The most significant clinically change was found in the lipid profile. Serum total, LDL, VLDL cholesterol, and triglyceride levels decreased significantly. Body weight, body fat weight, and Body Mass Index also decreased. Significant changes in serum TSH and salivary buffering capacity were also found. CONCLUSION Increasing the intake of boron through dietary means might contribute to beneficial effects on lipid metabolism, obesity, and thyroid metabolism; salivary boron may reflect serum boron; and boron may be used as a cariostatic agent in dentistry. An increased intake of other dietary factors such as fiber, potassium, iron, vitamin A, and vitamin E in the boron-rich foods might have been responsible of the effects described. To our knowledge, this study is the first clinical study in which dietary boron intake is increased via foods.

Abstract
Cardiovascular diseases (CVDs) are the first cause of death in the World. Mediator (MED) is an evolutionarily conserved protein complex, which mediates distinct protein-protein interactions. Pathogenic events in MED subunit have been associated with human diseases. Novel increasing evidence showed that missense mutations in MED13L gene are associated with transposition of great arteries while MED12, MED13, MED15, and MED30, have been correlated with heart development. Moreover, MED23 and MED25 have been associated with heart malformations in humans. Relevantly, MED1, MED13, MED14, MED15, MED23, MED25, and CDK8, were found modify glucose and/or lipid metabolism. Indeed, MED1, MED15, MED25, and CDK8 interact in the PPAR- and SREBP-mediated signaling pathways. MED1, MED14 and MED23 are involved in adipocyte differentiation, whereas MED23 mediates smooth muscle cell differentiation. MED12, MED19, MED23, and MED30 regulate endothelial differentiation by alternative splicing mechanism. Thus, MEDs have a central role in early pathogenic events involved in CVDs representing novel targets for clinical prevention and therapeutic approaches.

Abstract
Reynoutria multiflora (Thunb.) Moldenke (He Shou Wu) has been used for about 20 centuries as a Chinese medicinal herb for its activities of anticancer, anti-hyperlipidemia, and anti-aging. Previously, we found that He Shou Wu ethanol extract could induce apoptosis in hepatocellular carcinoma cells, and we also screened its active components. In this study, we investigated whether lowering lipid metabolism of emodin, a main active component in He Shou Wu, was associated with inhibitory effects in hepatocellular carcinoma cells. The correlation of apoptosis induction and lipid metabolism was investigated. The intrinsic apoptotic cell death, lipid production, and their signaling pathways were investigated in emodin-treated human hepatocellular carcinoma cells Bel-7402. The data showed that emodin triggered apoptosis in Bel-7402 cells. The mitochondrial membrane potential (ΔΨm) was reduced in emodin-treated Bel-7402 cells. We also found that emodin activated the expression of intrinsic apoptosis signaling pathway-related proteins, cleaved-caspase 9 and 3, Apaf 1, cytochrome c (CYTC), apoptosis-inducing factor, endonuclease G, Bax, and Bcl-2. Furthermore, the level of triglycerides and desaturation of fatty acids was reduced in Bel-7402 cells when exposed to emodin. Furthermore, the expression level of messenger RNA (mRNA) and protein of sterol regulatory element binding protein 1 (SREBP1) as well as its downstream signaling pathway and the synthesis and the desaturation of fatty acid metabolism-associated proteins (adenosine triphosphate citrate lyase, acetyl-CoA carboxylase alpha, fatty acid synthase (FASN), and stearoyl-CoA desaturase D) were also decreased. Notably, knock-out of SREBP1 in Bel-7402 cells was also found to induce less intrinsic apoptosis than did emodin. In conclusion, these results indicated that emodin could induce apoptosis in an SREBP1-dependent and SREBP1-independent manner in hepatocellular carcinoma cells.

Abstract
The Mediator complex plays a critical role in the regulation of transcription by linking transcription factors to RNA polymerase II. By examining mouse livers, we have found that in the fasted state, the Mediator complex exists primarily as an approximately 1.2-MDa complex, consistent with the size of the large Mediator complex, whereas following feeding, it converts to an approximately 600-kDa complex, consistent with the size of the core Mediator complex. This dynamic change is due to the dissociation and degradation of the kinase module that includes the MED13, MED12, cyclin-dependent kinase 8 (CDK8), and cyclin C (CCNC) subunits. The dissociation and degradation of the kinase module are dependent upon nutrient activation of mTORC1 that is necessary for the induction of lipogenic gene expression because pharmacological or genetic inhibition of mTORC1 in the fed state restores the kinase module. The degradation but not dissociation of the kinase module depends upon the E3 ligase, SCFFBW7 In addition, genetically insulin-resistant and obese db/db mice in the fasted state displayed elevated lipogenic gene expression and loss of the kinase module that was reversed following mTORC1 inhibition. These data demonstrate that the assembly state of the Mediator complex undergoes physiologic regulation during normal cycles of fasting and feeding in the mouse liver. Furthermore, the assembly state of the Mediator complex is dysregulated in states of obesity and insulin resistance.

Abstract
Boron is considered to be a biological trace element but there is substantial and growing support for it to be classified as an essential nutrient for animals and humans, depending on its speciation. Boron-containing compounds have been reported to play an important role in biological systems. Although the exact biochemical functions of boron-containing compounds have not yet been fully elucidated, previous studies suggest an active involvement of these molecules in the mediation of inflammation and oxidative stress. Chronic inflammation and oxidative stress are known to amplify the effects of the main cardiovascular risk factors: smoking, diet, obesity, arterial hypertension, dyslipidemia, type 2 diabetes (as modifiable risk factors), and hyperhomocysteinemia and age (as independent risk factors). However, the role of boron-containing compounds in cardiovascular systems and disease prevention has yet to be established. This paper is a review of boron-containing compounds' existence in nature and their possible functions in living organisms, with a special focus on certain cardiovascular risk factors that may be diminished by intake of these compounds, leading to a reduction of cardiovascular morbidity and/or mortality.

Abstract
Clear cell renal cell carcinoma (ccRCC), the most common type of kidney malignancy, is an incurable disease characterized by multiple metabolic abnormalities, especially lipid accumulation and desaturation. Though great progresses have been made in understanding the mechanisms of ccRCC, metabolic abnormalities remain largely unclear. Here, we found lncRNA LINC01138 is highly expressed in ccRCC and is associated with poor patient survival. LINC01138 regulates ccRCC growth through sterol regulatory element-binding protein 1 (SREBP1)-mediated lipid desaturation. Mechanistically, we demonstrated that LINC01138 interacts with PRMT5 to increase arginine methylation and protein stability of SREBP1, promoting lipid desaturation and cell proliferation in ccRCC. Our study identified LINC01138 as a novel regulator of metabolic abnormalities in ccRCC, providing a potential therapeutic target for metabolic therapy.

Abstract
Non-alcoholic steatohepatitis (NASH) is an inflammatory and progressive form of non-alcoholic fatty liver disease. However, there are no FDA-approved drugs for this condition. Lipids accumulated in NASH have a direct role in the progression of this disease. Therefore, this study for the first time explored the preventive effect of trans-chalcone on NASH through the modulation of sterol regulatory element binding protein (SREBP)-1c, SREBP-2, hepatic fatty acid synthesis (FAS) enzyme, proliferator-activated receptor (PPAR)-α, and PPAR-γ2 levels, which are involved in hepatic lipid metabolism. In this study, male rats were randomly divided into three groups (n = 7): Control, received 10% tween 80; NASH, received 10% tween 80 and 10 ml/kg high-fat emulsion (high-fat diet, HFD); and NASH + TC, received 20 mg/kg trans-chalcone and 10 ml/kg HFD. All treatments were performed by once-daily oral gavage for 6 weeks. Liver and blood samples were collected and serum levels of alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglyceride, total cholesterol, low-density lipoprotein (LDL)-cholesterol, and high-density lipoprotein (HDL)-cholesterol, as well as hepatic levels of SREBP-1c, SREBP-2, FAS, PPAR-α, and PPAR-γ2, were measured. Moreover, hematoxylin and eosin stained tissues were used for histological analysis. In this study, treatment of HFD-fed rats with trans-chalcone significantly reduced abnormalities in liver histology, serum levels of liver injury markers, liver index, and hepatic levels of SREBP-1c, SREBP-2, FAS, and PPAR-γ2. Furthermore, trans-chalcone significantly increased hepatic PPARα levels in these rats. Therefore, it seems that trans-chalcone protects the liver of HFD-fed rats against NASH development through reduction of SREBP-1c/ FAS- and PPAR-γ2-related lipogenesis, attenuation of SREBP-2-related cholesterol synthesis, and elevation of PPARα-related fatty acid oxidation.

BORON PREPARATIONS IN PSYCHIATRY AND NEUROLOGY: THEIR RISE, FALL AND RENEWED INTEREST. ACTA BIOMEDICA SCIENTIFICA 2018.

Abstract
The use of boron preparations (borax and boric acid) in medicine began long before their isolation in pure form. The mineral water of boron-containing sources has been historically used to treat skin diseases, to wash eyes, to disinfect wounds, etc. Also, what is of interest in the context of this article, boron-containing waters were used as calming, anti- anxiety, anticonvulsant and sleep-promoting remedy. In 1777, boric acid was first isolated from the mineral water of a healing spring source in Florence. Historically, first name of this compound was sal sedativum (“soothing salt”). However, the discovery of boron toxicity led to the cessation of its internal use. In recent decades, it has been found that boron is a microelement necessary for many metabolic processes in the body. It affects memory, cognitive functions, anxiety level, sleep, mood, regulates calcium and magnesium exchange, metabolism of vitamin D and sex steroids. It has been shown that some cases of treatment resistance to standard therapy, for example in epilepsy, anxiety and depression, are related to boron deficiency. In this regard, interest in the use of boron preparations in psychiatry and neurology, but in much smaller doses and on new scientific grounds, flared up again.

Abstract
Lipid metabolism reprogramming emerges as a new hallmark of malignancies. Sterol regulatory element-binding proteins (SREBPs), which are central players in lipid metabolism, are endoplasmic reticulum (ER)-bound transcription factors that control the expression of genes important for lipid synthesis and uptake. Their transcriptional activation requires binding to SREBP cleavageactivating protein (SCAP) to translocate their inactive precursors from the ER to the Golgi to undergo cleavage and subsequent nucleus translocation of their NH2-terminal forms. Recent studies have revealed that SREBPs are markedly upregulated in human cancers, providing the mechanistic link between lipid metabolism alterations and malignancies. Pharmacological or genetic inhibition of SCAP or SREBPs significantly suppresses tumor growth in various cancer models, demonstrating that SCAP/SREBPs could serve as promising metabolic targets for cancer therapy. In this review, we will summarize recent progress in our understanding of the underlying molecular mechanisms regulating SCAP/SREBPs and lipid metabolism in malignancies, discuss new findings about SREBP trafficking, which requires SCAP N-glycosylation, and introduce a newly identified microRNA-29-mediated negative feedback regulation of the SCAP/SREBP pathway. Moreover, we will review recently developed inhibitors targeting the SCAP/SREBP pathway for cancer treatment.

Abstract
Med15 is an important subunit of Mediator Tail module and is characterized by a KIX domain present towards amino terminal. In yeast and metazoans, Med15 KIX domain has been found to interact with various transcription factors regulating several processes including carbohydrate metabolism, lipogenesis, stress response and multidrug resistance. Mechanism of Med15 functioning in Arabidopsis is largely unknown. In this study, interactome of KIX domain of Arabidopsis Med15, AtMed15a, was characterized. We found 45 proteins that interact with AtMed15a KIX domain, including 11 transcription factors, 3 single strand nucleic acid-binding proteins and 1 splicing factor. The third helix of the KIX domain was found to be involved in most of the interactions. Mapping of the regions participating in the interactions revealed that the activation domain of a transcription factor, UKTF1 interacted with AtMed15a KIX domain. Thus, our results suggest that in Arabidopsis, activation domain of transcription factors target KIX domain of AtMed15a for their transcriptional responses.

Abstract
SCOPE Our recent study showed that the 1975 Japanese diet exhibited strong health benefits. In the current study, we aimed to develop a diet with even higher health benefits. METHODS First, to determine the characteristic components in the 1975 diet, we used mass spectrometry for analysis of Japanese diets from several years and performed principal component analysis. Next, a diet with an increased use frequency of foodstuffs contained characteristic components (the modified diet) was prepared and fed to mice. RESULTS Performed principal component analysis revealed that the 1975 diet contained 14 characteristic components that were found in fish, fruits, vegetables, seaweed, soybean foods, soup stock "dashi", and fermented seasoning. Based on these, the modified diet was prepared and fed to mice. The liver total cholesterol and serum LDL cholesterol decreased significantly in mice fed the modified diet and serum total cholesterol showed a downward trend, compared to mice fed the 1975 diet. There was no difference between the modified diet and the control groups. In addition, serum adiponectin level increased in mice fed the modified diet and serum TBARS and IL-6 levels decreased. CONCLUSION By modifying the 1975 diet, it was possible to make a diet with more benefit.

Abstract
The multisubunit Mediator is an evolutionary conserved transcriptional coregulatory complex in eukaryotes. It is needed for the transcriptional regulation of gene expression in general as well as in a gene specific manner. Mediator complex subunits interact with different transcription factors as well as components of RNA Pol II transcription initiation complex and in doing so act as a bridge between gene specific transcription factors and general Pol II transcription machinery. Specific interaction of various Mediator subunits with nuclear receptors (NRs) and other transcription factors involved in metabolism has been reported in different studies. Evidences indicate that ligand-activated NRs recruit Mediator complex for RNA Pol II-dependent gene transcription. These NRs have been explored as therapeutic targets in different metabolic diseases; however, they show side-effects as targets due to their overlapping involvement in different signaling pathways. Here we discuss the interaction of various Mediator subunits with transcription factors involved in metabolism and whether specific interaction of these transcription factors with Mediator subunits could be potentially utilized as therapeutic strategy in a variety of metabolic diseases.

Abstract
An insidious increase in the incidence of obesity, insulin resistance, and hyperlipidemia has led to an epidemic of type 2 diabetes worldwide. Tinospora crispa (T. crispa) is a familiar plant traditionally used in herbal medicine for diabetes; however, the major active ingredients of this plant are still unclear. In this study, we identified the therapeutic effects of borapetoside E, a small molecule extracted from T. crispa, in high-fat-diet (HFD)-induced obesity in mice. The therapeutic effects of borapetoside E in HFD-induced obese mice were assessed physiologically, histologically, and biochemically following intraperitoneal injection. Furthermore, we analyzed the expression of glucose and lipid metabolism-related genes and proteins in borapetoside E-treated obese mice. Compared with vehicle-treated mice, borapetoside E markedly improved hyperglycemia, insulin resistance, hepatic steatosis, hyperlipidemia, and oxygen consumption in obese mice, and the effects were comparable to or better than the drug metformin. In addition, borapetoside E suppressed the expression of sterol regulatory element binding proteins (SREBPs) and their downstream target genes related to lipid synthesis in the liver and adipose tissue. Borapetoside E showed beneficial effects in vivo, demonstrating that borapetoside E may be a potential therapy for the treatment of diet-induced type 2 diabetes and related metabolic syndromes.

Abstract
Obesity is a worldwide medical problem resulting in serious morbidity and mortality involving differentiation of pre-adipocytes into mature adipocytes (adipogenesis). Boron treatment has been reported to be associated with weight reduction in experimental animals; however, its effects on pre-adipocyte differentiation and anti-adipogenic molecular mechanisms are unknown. In this study, we demonstrate the inhibitory activities of boric acid (BA) and sodium pentaborate pentahydrate (NaB) on adipogenesis using common cellular models. Boron treatment repressed the expression of adipogenesis-related genes and proteins, including CCAAT-enhancer-binding protein α and peroxisome proliferator-activated receptor γ, by regulating critical growth factors and the β-catenin, AKT, and extracellular signal-regulated kinase signaling pathways. In addition, although boron treatment did not induce apoptosis in pre-adipocytes, it depressed mitotic clonal expansion by regulation of cell cycle genes. Overall, these data offer promising insights into the prevention/treatment of obesity and associated diseases.

Abstract
Brown adipose tissue is important for maintaining energy homeostasis and adaptive thermogenesis in rodents and humans. As disorders arising from dysregulated energy metabolism, such as obesity and metabolic diseases, have increased, so has interest in the molecular mechanisms of adipocyte biology. Using a functional screen, we identified cyclin C (CycC), a conserved subunit of the Mediator complex, as a novel regulator for brown adipocyte formation. siRNA-mediated CycC knockdown (KD) in brown preadipocytes impaired the early transcriptional program of differentiation, and genetic KO of CycC completely blocked the differentiation process. RNA sequencing analyses of CycC-KD revealed a critical role of CycC in activating genes co-regulated by peroxisome proliferator activated receptor γ (PPARγ) and CCAAT/enhancer-binding protein α (C/EBPα). Overexpression of PPARγ2 or addition of the PPARγ ligand rosiglitazone rescued the defects in CycC-KO brown preadipocytes and efficiently activated the PPARγ-responsive promoters in both WT and CycC-KO cells, suggesting that CycC is not essential for PPARγ transcriptional activity. In contrast, CycC-KO significantly reduced C/EBPα-dependent gene expression. Unlike for PPARγ, overexpression of C/EBPα could not induce C/EBPα target gene expression in CycC-KO cells or rescue the CycC-KO defects in brown adipogenesis, suggesting that CycC is essential for C/EBPα-mediated gene activation. CycC physically interacted with C/EBPα, and this interaction was required for C/EBPα transactivation domain activity. Consistent with the role of C/EBPα in white adipogenesis, CycC-KD also inhibited differentiation of 3T3-L1 cells into white adipocytes. Together, these data indicate that CycC activates adipogenesis in part by stimulating the transcriptional activity of C/EBPα.

Abstract
The Mediator complex was originally discovered in yeast, but it is conserved in all eukaryotes. Its best-known function is to regulate RNA polymerase II-dependent gene transcription. Although the mechanisms by which the Mediator complex regulates transcription are often complicated by the context-dependent regulation, this transcription cofactor complex plays a pivotal role in numerous biological pathways. Biochemical, molecular, and physiological studies using cancer cell lines or model organisms have established the current paradigm of the Mediator functions. However, the physiological roles of the mammalian Mediator complex remain poorly defined, but have attracted a great interest in recent years. In this short review, we will summarize some of the reported functions of selective Mediator subunits in the regulation of metabolism. These intriguing findings suggest that the Mediator complex may be an important player in nutrient sensing and energy balance in mammals.

Abstract
As a culinary and medicinal herb, rosemary is widely used. The present work aimed to investigate the effects of rosemary extracts on metabolic diseases and the underlying mechanisms of action. Liver cells stably expressing SREBP reporter were used to evaluate the inhibitory effects of different fractions of rosemary extracts on SREBP activity. The obese mice induced by Western-type diet were orally administered with rosemary extracts or vehicle for 7 weeks, the plasma and tissue lipids were analyzed. SREBPs and their target genes were measured by quantitative RT-PCR. We demonstrated that the petroleum ether sub-fraction of rosemary extracts (PER) exhibited the best activity in regulating lipid metabolism by inhibiting SREBPs, while water and n-BuOH sub-fraction showed the SREBPs agonist-effect. After PER treatment, there was a significant reduction of total SREBPs in liver cells. PER not only decreased SREBPs nuclear abundance, but also inhibited their activity, resulting in decreased expression of SREBP-1c and SREBP-2 target genes in vitro and in vivo. Inhibiting SREBPs by PER decreased the total triglycerides and cholesterol contents of the liver cells. In the mice fed with Western-type diet, PER treatment decreased TG, TC, ALT, glucose, and insulin in blood, and improved glucose tolerance and insulin sensitivity. Furthermore, PER treatment also decreased lipid contents in liver, brown adipose tissue, and white adipose tissue. Our results from the present study suggested that petroleum ether fraction of rosemary extracts exhibited the best potential of improving lipid metabolism by inhibiting SREBPs activity.

Abstract
Over the past few decades, mortality resulting from cardiovascular disease (CVD) steadily decreased in western countries; however, in recent years, the decline has become offset by the increase in obesity. Obesity is strongly associated with the metabolic syndrome and its atherogenic dyslipidemia resulting from insulin resistance. While lifestyle treatment would be effective, drugs targeting individual risk factors are often required. Such treatment may result in polypharmacy. Novel approaches are directed towards the treatment of several risk factors with one drug. Studies in animal models and humans suggest a central role for sterol regulatory-element binding proteins (SREBPs) in the pathophysiology of the metabolic syndrome. Four recent studies targeting the maturation or transcriptional activities of SREBPs provide proof of concept for the efficacy of SREBP inhibition in this syndrome.

Abstract
Sterol regulatory element-binding protein 1 (SREBP1) is a known transcription factor of lipogenic genes, which plays important roles in regulating de novo lipogenesis. Accumulating evidences indicate SREBP1 is involved in tumorigenesis, yet its role in pancreatic cancer remains unclear. Here, we explored the expression characteristic and function of SREBP1 in pancreatic cancer. Analysis of 60 patients with pancreatic ducat cancer showed that SREBP1 level was significantly higher in pancreatic cancer than that in adjacent normal tissues. High expression of SREBP1 predicted poor prognosis in patients with pancreatic cancer. Multivariate analysis revealed that SREBP1 was an independent factor affecting overall survival. SREBP1 silencing resulted in proliferation inhibition and induction of apoptosis in pancreatic cancer cells. Mechanistically, lipogenic genes (acetyl-CoA carboxylase (ACC), fatty acid synthase (FASN), and stearoyl-CoA desaturase-1 (SCD1)) and de novo lipogenesis were promoted by SREBP1. Inhibition of lipogenic genes through specific inhibitors ablated SREBP1-mediated growth regulation. Furthermore, depletion of SREBP1 could suppress lipid metabolism and tumor growth in vivo. Our results indicate that SREBP1 had important role in tumor progression and appears to be a novel prognostic marker for pancreatic cancer.

Abstract
Adipocyte differentiation and the extent of subsequent fat accumulation are closely related to the occurrence and progression of diseases such as insulin resistance and obesity. Black soybean koji (BSK) is produced by the fermentation of black soybean with Aspergilllus awamori. Previous study indicated that BSK extract has antioxidative and multifunctional bioactivities, however, the role of BSK in the regulation of energy metabolism is still unclear. We aimed to investigate the effect of glucose utilization on insulin-resistant 3T3-L1 preadipocytes and adipogenesis-related protein expression in differentiated adipocytes with BSK treatment. Cytoxicity assay revealed that BSK did not adversely affect cell viability at levels up to 200 µg/mL. The potential for glucose utilization was increased by increased glucose transporter 1 (GLUT1), GLUT4 and protein kinase B (AKT) protein expression in insulin-resistant 3T3-L1 cells in response to BSK treatment. Simultaneously, BSK inhibited lipid droplet accumulation in differentiated 3T3-L1 cells. The inhibitory effect of adipogenesis was associated with downregulated peroxisome proliferator-activated receptor g (PPARγ) level and upregulated Acrp30 protein expression. Our results suggest that BSK extract could improve glucose uptake by modulating GLUT1 and GLUT4 expression in a 3T3-L1 insulin-resistance cell model. In addition, BSK suppressed differentiation and lipid accumulation in mature 3T3-L1 adipocytes, which may suggest its potential for food supplementation to prevent obesity and related metabolic abnormalities.
