[PMID: 36933872 DOI: 10.1016/j.jep.2023.116358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 02/18/2023] [Accepted: 03/03/2023] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Jiawei Yanghe Decoction (JWYHD) is a widely used traditional Chinese medicine prescription in the clinical setting for the treatment of autoimmune diseases. Many studies showed that JWYHD has anti-tumor activities in cell and animal models. However, the anti-breast cancer effects of JWYHD and the underlying mechanisms of action remain unknown. AIM OF STUDY This study aimed to determine the anti-breast cancer effect and reveal the underlying mechanisms of action in vivo, in vitro and in silico. MATERIALS AND METHODS Orthotopic xenograft breast cancer mouse model and inflammatory zebrafish model were used to observe the anti-tumor effect and immune cell regulation of JWYHD. Moreover, the anti-inflammatory effect of JWYHD were evaluated by the expression of RAW 264.7 cells. JWYHD active ingredients were obtained by UPLC-MS/MS and potential targets were screened by network pharmacology. The therapeutic targets and signaling pathways predicted by computer were assessed by Western blot, real-time PCR (RT-PCR), immunohistochemistry (IHC) staining, and Enzyme-linked immunosorbent assays (ELISA) to explore the therapeutic mechanism of JWYHD against breast cancer. At last, Colivelin and Stattic were used to explore the effect of JWYHD on JAK2/STAT3 pathway. RESULTS JWYHD significantly decreased the tumor growth in a dose-dependent manner in the orthotopic xenograft breast cancer mouse model. Flow cytometry and IHC results indicated that JWYHD decreased the expressions of M2 macrophages and Treg while increasing M1 macrophages. Meanwhile, ELISA and Western blot results showed a decrease in IL-1β, IL-6, TNFα, PTGS2 and VEGFα in tumor tissue of JWYHD groups. The results were also verified in LPS-induced RAW264.7 cells and zebrafish inflammatory models. TUNEL assay and IHC results showed that JWYHD significantly induced apoptosis. Seventy-two major compounds in JWYHD were identified by UPLC-MS/MS and Network pharmacology. It was found that the significant binding affinity of JWYHD to TNFα, PTGS2, EGFR, STAT3, VEGFα and their expressions were inhibited by JWYHD. IHC and Western blot analysis showed that JWYHD could decrease the expression of JAK2/STAT3 pathway. Furthermore, Colivelin could reverse the decrease effect of JWYHD in vitro. CONCLUSION JWYHD exerts a significant anti-tumor effect mainly by inhibiting inflammation, activating immune responses and inducing apoptosis via the JAK2/STAT3 signaling pathway. Our findings provide strong pharmacological evidence for the clinical application of JWYHD in the management of breast cancer.

Abstract
Myrosinase (Myr) is a type of critical β-thioglucosidase enzyme activator essential for sustaining many functional foods to perform their health-promoting functions. An accurate and reliable Myr test is meaningful for food quality and dietary nutrition assessments, whereas the currently reported methods do not guarantee specificity and have high reliance on instrumentation, which are not suitable for rapid and onsite Myr screening especially in complex systems from various sources. Herein, we present a unique NIR-II absorption-based photothermal-responsive colorimetric biosensor for anti-interference onsite Myr determination and realization of rapid visualized outputs with the aid of smartphone calculation. Typically, assisted by glucose oxidase (GOx), Myr specifically converts the sinigrin substrate into hydrogen peroxide (H2O2) that can oxidize 3,3',5,5'-tetramethylbenzidine (TMB) catalyzed by AuNPs to form a charge transfer complex (CTC) with NIR-II absorption and photothermal characters. Delightfully, such a proposed method is able to determine Myr within a wide range of 0 to 172.5 mU/mL with a detection limit down to 2.96 mU/mL. Moreover, simple, rapid, and real-time visual Myr identification in actual food-sourced samples could also be readily achieved by smartphone readout processing, with the promising advantages of anti-interference, high accuracy, and low cost as well as labor-saving and intelligence engagement, thus providing great feasibility for precise measurement in complex and dynamic dietary sample analysis. Overall, our proposed method presents a novel technology for onsite dietary Myr enzyme profiling, which is promising to be applied in the food industry for nutritional composition profiles, freshness evaluation, and quality assessment.

Abstract
Traditionally, Brassica species are widely used in traditional medicine, human food, and animal feed. Recently, special attention has been dedicated to Brassica seeds as source of health-promoting phytochemicals. This review provides a summary of recent research on the Brassica seed phytochemistry, bioactivity, dietary importance, and toxicity by screening the major online scientific database sources and papers published in recent decades by Elsevier, Springer, and John Wiley. The search was conducted covering the period from January 1964 to July 2022. Phytochemically, polyphenols, glucosinolates, and their degradation products were the predominant secondary metabolites in seeds. Different extracts and their purified constituents from seeds of Brassica species have been found to possess a wide range of biological properties including antioxidant, anticancer, antimicrobial, anti-inflammatory, antidiabetic, and neuroprotective activities. These valuable functional properties of Brassica seeds are related to their richness in active compounds responsible for the prevention and treatment of various chronic diseases such as obesity, diabetes, cancer, and COVID-19. Currently, the potential properties of Brassica seeds and their components are the main focus of research, but their toxicity and health risks must also be accounted for.

Antioxidants (Basel) 2022; 11:antiox11071298. [PMID: 35883789 PMCID: PMC9312100 DOI: 10.3390/antiox11071298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 06/25/2022] [Accepted: 06/25/2022] [Indexed: 11/16/2022] Open
Abstract
Broccoli is becoming increasingly popular among consumers owing to its nutritional value and rich bioactive compounds, such glucosinolates (GSLs) and hydrolysis products, which are secondary metabolites for plant defense, cancer prevention, and higher antioxidant activity for humans. In this study, 40 μmol/L methyl jasmonate (MeJA) was sprayed onto broccoli from budding until harvest. The harvested broccoli florets, stem, and leaves were used to measure the contents of GSLs, sulforaphane, total phenolics, and flavonoids, as well as myrosinase activity, antioxidant activity, and gene expression involved in GSL biosynthesis. The overall results revealed that GSL biosynthesis and sulforaphane accumulation were most likely induced by exogenous MeJA treatment by upregulating the expression of CYP83A1, SUR1, UGT74B1, and SOT18 genes. Exogenous MeJA treatment more remarkably contributed to the increased GSL biosynthesis in broccoli cultivars with low-level GSL content (Yanxiu) than that with high-level GSLs (Xianglv No.3). Moreover, MeJA treatment had a more remarkable increasing effect in broccoli florets than stem and leaves. Interestingly, total flavonoid content substantially increased in broccoli florets after MeJA treatment, but total phenolics did not. Similarly, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity, trolox-equivalent antioxidant capacity (ABTS), and ferric-reducing antioxidant power (FRAP) were higher in broccoli floret after MeJA treatment. In conclusion, MeJA mediated bioactive compound metabolism, had positive effects on GSL biosynthesis, sulforaphane, and flavonoids accumulation, and showed positive correlation on inducing higher antioxidant activities in broccoli floret. Hence, preharvest supplementation with 40 μM MeJA could be a good way to improve the nutritional value of broccoli florets.

Kinetic Study and Modeling of Wild-Type and Recombinant Broccoli Myrosinase Produced in E. coli and S. cerevisiae as a Function of Substrate Concentration, Temperature, and pH. Catalysts 2022.

Abstract
The myrosinase enzyme hydrolyzes glucosinolates, among which is glucoraphanin, the precursor of the anticancer isothiocyanate sulforaphane (SFN). The main source of glucoraphanin is Brassicaceae; however, its natural concentration is relatively low, limiting the availability of SFN. An option to obtain SFN is its exogenous production, through enzymatic processes and under controlled conditions, allowing complete conversion of glucoraphanin to SFN. We characterized the kinetics of wild-type (BMYR) and recombinant broccoli myrosinases produced in E. coli (EMYR) and S. cerevisiae (SMYR) in terms of the reaction conditions. Kinetics was adjusted using empirical and mechanistic models that describe reaction rate as a function of substrate concentration, temperature, and pH, resulting in R2 values higher than 90%. EMYR kinetics differed significantly from those of BMYR and SMYR probably due to the absence of glycosylations in the enzyme produced in E. coli. BMYR and SMYR were subjected to substrate inhibition but followed different kinetic mechanisms attributed to different glycosylation patterns. EMYR (inactivation Ea = 76.1 kJ/mol) was more thermolabile than BMYR and SMYR. BMYR showed the highest thermostability (inactivation Ea = 52.8 kJ/mol). BMYR and EMYR showed similar behavior regarding pH, with similar pK1 (3.4 and 3.1, respectively) and pK2 (5.4 and 5.0, respectively), but differed considerably from SMYR.
