“…Neuronal cell death caused by oxidative stress contributes to the pathogenesis of neurodegenerative diseases, such as Alzheimer’s disease and Parkinson’s disease. Because they contain high amounts of phenolic compounds, unsaturated oils and proteins, soybeans are a food with high nutritional value as well as antioxidant and anticancer properties due to their active metabolites [9]. Previous studies reported that soybean isoflavones may also have neuroprotective effects due to their strong antioxidant and anti-inflammatory activities [40].…”

“…Isoflavones are phytoestrogens with potent estrogenic activity; Genistein, Daidzein, and glycitein are the most active of the isoflavones found in soybeans [7,8]. Soy metabolites, namely isoflavones, unsaturated fatty acids, and saponins, possess great potential for human health due to their antioxidant and anti-carcinogenic activity [9]. Soy isoflavones, or phytoestrogens from soy, have been shown to be strongly associated with anticancer activity and inhibition of the epidermal growth factor receptor tyrosine kinase [10].…”

Estrogen deficiency has been well characterized in inflammatory disorders including neuroinflammation. Daidzein, a dietary alternative phytoestrogen found in soy (Glycine max) as primary isoflavones, possess anti-inflammatory activity, but the effect of its active metabolite Equol (7-hydroxy-3-(4′-hydroxyphenyl)-chroman) has not been well established. In this study, we investigated the anti-neuroinflammatory and neuroprotective effect of Equol in vitro. To evaluate the potential effects of Equol, three major types of central nervous system (CNS) cells, including microglia (BV-2), astrocytes (C6), and neurons (N2a), were used. Effects of Equol on the expression of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX-2), Mitogen activated protein kinase (MAPK) signaling proteins, and apoptosis-related proteins were measured by western blot analysis. Equol inhibited the lipopolysaccharide (LPS)-induced TLR4 activation, MAPK activation, NF-kB-mediated transcription of inflammatory mediators, production of nitric oxide (NO), release of prostaglandin E2 (PGE-2), secretion of tumor necrosis factor-α (TNF-α) and interleukin 6 (IL-6), in Lipopolysaccharide (LPS)-activated murine microglia cells. Additionally, Equol protects neurons from neuroinflammatory injury mediated by LPS-activated microglia through downregulation of neuronal apoptosis, increased neurite outgrowth in N2a cell and neurotrophins like nerve growth factor (NGF) production through astrocytes further supporting its neuroprotective potential. These findings provide novel insight into the anti-neuroinflammatory effects of Equol on microglial cells, which may have clinical significance in cases of neurodegeneration.

“…According to our research, imbalanced water conditions with moderate water reduction can improve soybean seed-quality and drought-resistant genotypes can increase the soybean yield under intercropping systems (Iqbal et al, 2018a). Similarly, appropriate intercropping shading can improve the flavor quality of soybean seeds under maize-soybean intercropping system (Liu et al, 2016). Therefore, combined stresses (imbalance water deficit and shade) appear in intercropping systems could make the problem more complex and interesting.…”

A half-root stress is a half portion of the root system exposed to treatment while the remaining half portion kept under normal conditions. A half-root stress including half-root drought stress, half-root nutrient stress, and half-root salinity stress has become a general approach to improve plant performance and adaptability. Plants produce some chemical signals in stressed part of root, and other parts sense these signals to improve the acclimation and adaptive responses to environmental stresses. Plants adapt the compensatory functions and discriminate the systemic and local regulatory mechanisms, but the understanding of these mechanisms is controversial. Chemical signals (Abscisic acid, sap pH, cytokinins, content of malate, amino acid, and ureide) have been involved in root to shoot signaling under half-root stress. Furthermore, naturally appeared half-root stress in intercropping systems could be an additional attribute of half-root stress approach. Therefore, much more study is required to elaborate its acceptability in intercropping. In this review, we summarized the current knowledge and identified some key future researches areas regarding half-root stress approach. ARTICLE HISTORY

“…Extraction and chromatographic analysis procedures were based on previously published methods, with certain modifications (Zhang et al, 2011; Liu et al, 2016). Twelve common isoflavones and eight anthocyanins were quantified by external standardization using an Agilent 1260-series high performance liquid chromatography (HPLC) system equipped with a mass spectrometric detector (Agilent Quadrupole LC/MS 6120).…”

Prolonged, continuous rainfall is the main climatic characteristic of autumn in Southwest China, and it has been found to cause mildew outbreaks in pre-harvest soybean fields. Low temperature and humidity (LTH) stress during soybean maturation in the field promotes pre-harvest mildew, resulting in damage to different organs of soybean fruits to different extents, but relatively little information on the resistance mechanisms in these fruits is available. Therefore, to understand the metabolic responses of soybean fruits to field mold (FM), the metabonomic variations induced by LTH were characterized using proton nuclear magnetic resonance spectroscopy (1H-NMR), and the primary metabolites from the pod, seed coat and cotyledon of pre-harvest soybean were quantified. Analysis of FM-damaged soybean germplasms with different degrees of resistance to FM showed that extracts were dominated by 66 primary metabolites, including amino acids, organic acids and sugars. Each tissue had a characteristic metabolic profile, indicating that the metabolism of proline in the cotyledon, lysine in the seed coat, and sulfur in the pod play important roles in FM resistance. The primary-secondary metabolism interface and its potential contribution to FM resistance was investigated by targeted analyses of secondary metabolites. Both the seed coat and the pod have distinct but nonexclusive metabolic responses to FM, and these are functionally integrated into FM resistance mechanisms.
