Genome-wide identification and characterization of the WOX gene family in Brassica juncea / 生物工程学报

The WUSCHEL related-homeobox (WOX) family is one of the plant-specific transcription factor families, playing important roles in plant growth and development. In this study, 51 WOX gene family members were identified from the genome data of Brassica juncea by searching and screening with HUMMER, Smart and other software. Their protein molecular weight, amino acids numbers, and isoelectric point were analyzed by using Expasy online software. Furthermore, bioinformatics software was used to systematically analyze the evolutionary relationship, conservative region, and gene structure of the WOX gene family. The mustard WOX gene family was divided into three subfamilies: ancient clade, intermediate clade, and WUS clade/modern clade. Structural analysis showed that the type, organization form and gene structure of the conservative domain of WOX transcription factor family members in the same subfamily were highly consistent, while there was a certain diversity among different subfamilies. 51 WOX genes are distributed unevenly on 18 chromosomes of mustard. Most of the promoters of these genes contain cis acting elements related to light, hormone and abiotic stress. Using transcriptome data and real-time fluorescence quantitative PCR (qRT-PCR) analysis, it was found that the expression of mustard WOX gene was spatio-temporal specific, among which BjuWOX25, BjuWOX33, and BjuWOX49 might play an important role in the development of silique, and BjuWOX10, BjuWOX32, and BjuWOX11, BjuWOX23 respectively might play an important role in the response to drought and high temperature stresses. The above results may facilitate the functional study of mustard WOX gene family.

Mutant construction of HDA9 and its interactions with promoters of flowering integrator SOC1 and AGL24 in Brassica juncea / 生物工程学报

HDA9, a member of the deacetylase family, plays a vital role in regulating plant flowering time through flowering integrator SOC1 and AGL24. However, it remains elusive how HDA9 interacts with SOC1 and AGL24 in flowering time control. Here, HDA9 was cloned in Brassica juncea and then its three active sites were separately replaced with Ala via overlap extension PCR. Thus, mutants of HDA9(D172A), HDA9(H174A) and HDA9(D261A) were constructed and fused into the pGADT7 vector. The yeast one-hybrid assays indicated that HDA9 mutants remained the interactions with the promoters of SOC1 and AGL24. Furthermore, the aforementioned results were confirmed in the dual luciferase assays. Interestingly, the DNA-protein interactions were weakened significantly due to the mutation in the three active sites of HDA9. It suggested that flowering signal integrator SOC1 and AGL24 were regulated by the key amino acid residues of 172th, 174th and 261th in HDA9. Our results provide valuable information for the in-depth study of the biological function and molecular regulation of HDA9 in Brassica juncea flowering time control.

Effects of methanolic extract of Brassica juncea seeds on biochemical parameters and histological integrity of the heart and liver of albino rats / Efectos del extracto metanólico de las semillas de Brassica juncea sobre los parámetros bioquímicos y la integridad histológica del corazón y el hígado de ratas albinas

SUMMARY: Brassica juncea (Indian mustard) seeds are consumed in treatment of high blood pressure, headache and prevention of heart disease. The aim of the present study was to investigate the effects of methanol extract of Brassica juncea seeds [BJME] on the heart and liver of adult Albino Wistar rats. A total of 24 albino rats of both sexes were divided into 6 groups [I - VI] of 4 rats per group. Groups I to IV received graded doses of the methanol extract by oral gavage while groups V and VI (controls) received 2 ml/kg body weight of 3 % Tween 80 and water respectively via oral gavage once daily. Treatment lasted for four weeks and the serum levels of aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP) were estimated. The animals were sacrificed and the heart and liver tissues were excised for further histological processing for light microscopy. There was significant increase in AST and ALT levels following BJME treatment when compared to the controls. ALP activity did not differ significantly among the treatment and control groups. Histopathological changes consistent with toxic injury were observed in the heart and liver tissues of BJME- treated rats. In conclusion, the results of this study show that sub-acute administration of methanol seed extract of Brassica juncea can exert cardiotoxic and hepatotoxic effects in rats.

The effects of Brassica juncea L. leaf extract on obesity and lipid profiles of rats fed a high-fat/high-cholesterol diet

BACKGROUND/OBJECTIVES: Obesity is a global health problem of significant importance which increases mortality. In place of anti-obesity drugs, natural products are being developed as alternative therapeutic materials. In this study, we investigated the effect of Brassica juncea L. leaf extract (BLE) on fat deposition and lipid profiles in high-fat, high-cholesterol diet (HFC)-induced obese rats. MATERIALS/METHODS: Male Sprague-Dawley rats were divided into four groups (n = 8 per group) according to diet: normal diet group (ND), high-fat/high-cholesterol diet group (HFC), HFC with 3% BLE diet group (HFC-A1), and HFC with 5% BLE diet group (HFC-A2). Each group was fed for 6 weeks. Rat body and adipose tissue weights, serum biochemical parameters, and tissue lipid contents were determined. The expression levels of mRNA and proteins involved in lipid and cholesterol metabolism were determined by reverse transcription polymerase chain reaction and western blot analysis, respectively. RESULTS: The HFC-A2 group showed significantly lower body weight gain and food efficiency ratio than the HFC group. BLE supplementation caused mesenteric, epididymal, and total adipose tissue weights to decrease. The serum levels of triglyceride, total cholesterol, and low-density lipoprotein cholesterol were significantly reduced, and high-density lipoprotein cholesterol was significantly increased in rats fed BLE. These results were related to lower glucose-6-phosphate dehydrogenase, acetyl-coA carboxylase, and fatty acid synthase mRNA expression, and to higher expression of the cholesterol 7α-hydroxylase and low density lipoprotein-receptor, as well as increased protein levels of peroxisome proliferator-activated receptor α. Histological analysis of the liver revealed decreased lipid droplets in HFC rats treated with BLE. CONCLUSIONS: Supplementation of HFC with 3% or 5% BLE inhibited body fat accumulation, improved lipid profiles, and modulated lipogenesis- and cholesterol metabolism-related gene and protein expression.

An iodine database establishment and iodine intake in Korean adults: Based on the 1998~2014 Korea National Health and Nutrition Examination Survey / 한국영양학회지

PURPOSE: This study analyzed iodine intake by establishing an iodine database of general Korean foods eaten by Korean adults based on the data from the 1998 ~ 2014 KNHANES (Korea National Health and Nutrition Examination Survey). METHODS: Data on 56,818 subjects aged 19 years and older were obtained from health behavior interviews and a 24-hour dietary recall survey. Iodine intake of subjects was analyzed according to general characteristics, dietary lifestyle, food groups, and cooking method. RESULTS: An iodine database was established for 312 food items. The mean iodine intake of Korean adults decreased from 641.6 μg in 1998 to 236.2 μg in 2014 per day. Iodine intake of women was higher than that of men. For age distribution, those aged 30 ~ 49 years constituted more than 39 ~ 46% of subjects by survey year. Regarding iodine intake according to dietary lifestyle, the highest iodine intake was 29.4 ~ 34.4% for lunch while that of breakfast decreased. The highest iodine contribution by food group was seaweed such as kelp, sea mustard, and laver. CONCLUSION: The results of this study indicate that iodine intake of Korean adults has been decreasing, and iodine intake is associated with the prevalence of thyroid disease. This study provides basic data for the estimation of iodine intake in Korean adults.

El perfil de ácidos grasos de la semillas de mostaza negra muestran que el ácido graso predominante es el oleico (22,96%), seguido por linoleico (6,63%) y linolénico (3,22%), mientras que para la semilla de mostaza amarilla es el erúcico (6,87%), seguido por oleico (5,08%) y linoléico (1,87%).

The composition, some physical properties (density, refraction index, and color), antioxidant capacity (DPPH), and fatty acid profile of seeds of black (Brassica nigra) or yellow mustard (Brassica alba) were evaluated, as well as for their oils and residues from oil extraction. Density of the black and yellow mustard oils were 0.912 ± 0.01 and 0.916 ± 0.01 g/mL, respectively; their refraction indexes were 1.4611 ± 0.01 and 1.4617 ± 0.01, respectively; being not significantly different (p>0.05) between two mustards. Color parameters of the black and yellow mustard oils presented greenish-yellow tones and reddish-yellow tones, respectively; regarding antioxidant activities, these ranged from 25 mg equivalents of Trolox/100 g in the yellow mustard oil to 1,366 mg equivalents of Trolox/100 g in the residues from oil extraction of black seed mustard. The fatty acid profile of the black mustard seed revealed that its predominant fatty acid is oleic (22.96%), followed by linoleic (6.63%) and linolenic (3.22%), whereas for yellow mustard seed the major fatty acid is erucic (6.87%), followed by oleic (5.08%) and linoleic (1.87%) acids.

A Case of Anaphylaxis Induced by Contact with Young Radish (Raphanus sativus L)

Young radish (Raphanus sativus L), a member of the mustard family (Cruciferae), is a common ingredient of Kimchi. Although few reports have described anaphylaxis to cruciferous vegetables, we report the case of anaphylaxis induced by contact with young radish. A 46-year-old female with a history of contact allergy to metal presented to our emergency room (ER) with dizziness, generalized eruption and gastrointestinal upset. Her symptoms developed after re-exposure to young radish while chopping it. Hypotensive blood pressures were noted. Three days prior, the patient had experienced generalized urticaria with pruritus immediately after chopping the fresh young radish, which resolved spontaneously. In the ER, her symptoms improved by the administration of epinephrine (0.3 mL), antihistamine (chlorpheniramine) and isotonic saline hydration. A skin prick test with young radish extract showed positive reactivity. The same skin test was negative in five adult controls. IgE-mediated hypersensitivity could be an important immunologic mechanism in the development of young radish-induced anaphylaxis.

The Effects of an Extract of Atractylodes Japonica Rhizome, SKI3246 on Gastrointestinal Motility in Guinea Pigs

BACKGROUND/AIMS: There are limited therapeutic options available for irritable bowel syndrome with diarrhea (IBS-D). We tested the effects of Atractylodes japonica rhizome, a perennial plant native to North Asia, on both upper and lower gastrointestinal (GI) motility in guinea pigs. METHODS: The extract of A. japonica rhizome was administered orally at different doses to test its effects on upper GI motility as determined from charcoal transit in native guinea pigs and in guinea pigs pretreated with thyrotropin-releasing hormone or mustard oil. Regarding its effect on lower GI motility, the removed guinea pig colon was suspended in a chamber containing Krebs-Henseleit solution and the transit time of artificial feces was measured with various dilutions of the extract. As for in vivo assay, weight and number of fecal pellets expelled were determined under the same drug preparation used in upper GI motility experiment. RESULTS: The extract of A. japonica rhizome had no significant effect on upper GI motility in either normal or altered physiological states. However, the extract increased colonic transit time in the in vitro model. In the fecal expulsion study, the cumulative weight and number of pellets did not differ significantly between the control group and groups treated with the extracts. In the animals pretreated in vivo with thyrotropin-releasing hormone, however, the weight and number of fecal pellets were significantly decreased in animals treated with 300 mg/kg and 600 mg/kg doses of extract. CONCLUSIONS: Our findings suggest that the extract of A. japonica rhizome can be a potential agent for IBS-D.

Antidepressant-like effects of Brassica juncea L. leaves in diabetic rodents.

The objective of the study was to evaluate for antidepressant like activity of a methanolic extract of B. juncea leaves (BJ 100, 200, and 400 mg/kg/day, po), and Imipramine (15 mg/kg/day, po) in alloxan monohydrate (120 mg/kg, ip) induced diabetic and nondiabetic rodents, using behavioural despair, learned helplessness, and tail suspension tests for antidepressants and locomotor activity test for quantifying the behavioural effects of treatments. In addition, effects of BJ treatments on brain levels of norepinephrine, serotonin and dopamine were also estimated. Enhanced depressive states, and motility were observed in diabetic animals. Antidepressant and motor function depressing effects of BJ were apparent in all behavioural tests in diabetic rats and mice only. Decreased contents of dopamine, norepinephrine and serotonin in brain of diabetic rats were also dose dependently compensated by repeated daily BJ treatments. However, brain dopamine level of BJ treated normal rats was higher than that in control nondiabetic. The results suggest that BJ could be a nutritional alternative for combating exaggerated depression commonly associated with diabetes.

Preparation, in vitro and in vivo evaluation of cataplasm of white mustard seed varnish to prevent asthma / 中国中药杂志

The aim of the manuscript was to optimize formulations and preparation technologies of cataplasm of white mustard seed varnish, and to evaluate its anti-asthma effect on rats. The single factor experiments included spreading thickness, types of crosslinking agents, dihydroxyaluminum aminoacetate amount, sodium polyacrylate amount, types of adhesive agents with human sense as the evaluation index. Blank cataplasm matrix was optimized by the orthogonal experiment with the amount of glycerine, citric acid, and sodium carboxymethylcellulose as the major influential factors. Initial adhesive force, peeling strength and human sense were as the evaluation index. The optimized formulation of blank cataplasm were as followings: glycerine-water-ethanol-PEG400-dihydroxyaluminum aminoacetate-citric acid-sodium carboxymethylcellulose-sodium carboxymethylcellulose 2 : 8 : 0.8 : 0.4 : 0.07: 0.15 : 0.1 : 0.5. The active ingredients of white mustard seed, corydalis, and gansui root were extracted by alcohol extraction method. Asiasarum volatile oil was extracted by oil extractor. The optimized drug loading amount was 11% with initial adhesive force, peeling strength and human sense as the evaluation index. Asthma rats model were established by sensitized with ovalbumin and nose-scratching time as the evaluation index. High dose (17%) group of drug-loaded cataplasm had the obvious inhibition effect on nose-scratching time of rats (P = 0.037 < 0.05). In comparison, middle dose (11%), low dose (4%) and positive-control groups had no obvious inhibitive effect on rats. White mustard seed cataplasm supplied a novel choice for anti-asthma therapy. And the overall pharmacodynamics assessment will be carried out on molecular level in near future.

Hypersensitivity to pollen of four different species of Brassica: a clinico-immunologic evaluation in patients of respiratory allergy in India

BACKGROUND: Rapeseed-mustard is the second most important source of edible oil in India. Several species of Brassica are grown in different parts of country for its oilseeds. OBJECTIVE: The objective was to investigate allergenicity to antigenic extracts of pollen of 4 species of Brassica. METHODS: Brassica campestris, Brassica juncea, Brassica nigra, and Brassica napus were selected for the detailed investigation. Pollen samples from each of the four species were collected from the polliniferous materials. The antigenic and allergenic profiles of these extracts were evaluated by means of sodium dodecyl sulfate-polyacrylamide gel electrophoresis, Skin prick test, enzyme linked immuno sorbent assay and Western blot on atopic individuals. RESULTS: Out of the 159 atopic subjects tested, 21.38% were positive to at least one or other species of Brassica pollen, with highest skin positivity (13.20%) to B. campestris extract. Raised IgE with significant linear correlation with intensity of skin reactions was obtained. Protein fractions of 20, 25, 32, 37, 56, and 90 kDa were recognized by B. campestris and B. juncea whereas 56, 76, 87, and 90 kDa were recognized by B. nigra and B. napus as major IgE binding protein fractions. The patients also showed positivity to other inhalant pollen allergens tested. CONCLUSION: IgE mediated hypersensitivity varied from 4.40% to 13.20% in Indian atopic subjects to pollen of one or the other species of Brassica. Protein fractions of 47, 56, 76, 87, and 90 kDa were identified as IgE binding by all the four species, however individual heterogeneity exists. Thus a local species may be more pertinent for immunotherapy. The major allergen needs to be further characterized.

Effect of cadaverine on Brassica juncea (L.) under multiple stress.

The cadaverine (Cad), an organic diamine was examined for its response on growth in salinity and metal stressed B. juncea cv RH-30 vis-à-vis compared the response of ammonium nitrate. The Cad (1 mM) application ameliorated the effect caused by salinity and metal stress on seed germination and plant growth. The plant growth recovery (dry biomass accumulation) was dependent on stress and diamine type. The higher growth recovery potential of Cad under both stresses was due to elevation in photosynthetic pigments, nitrate reductase activity and organic nitrogen as well as soluble protein, It is inferred that growth in stressed seedlings was mediated by Cad through lowering endogenous Cd/Pb and Na+/K+ level in leaf and shoot tissues.

Use of Plackett-Burman design for rapid screening of nitrogen and carbon sources for the production of lipase in solid state fermentation by Yarrowia lipolytica from mustard oil cake (Brassica napus)

Mustard oil cake (Brassica napus), the residue obtained after extraction of mustard oil from mustard oil seeds, was investigated for the production of lipase under solid state fermentation (SSF) using the marine yeast Yarrowia lipolytica NCIM 3589. Process parameters such as incubation time, biomass concentration, initial moisture content, carbon source concentration and nitrogen source concentration of the medium were optimized. Screening of ten nitrogen and five carbon sources has been accomplished with the help of Plackett-Burman design. The highest lipase activity of 57.89 units per gram of dry fermented substrate (U/gds) was observed with the substrate of mustard oil cake in four days of fermentation.

Effects of Ramosetron on Gastrointestinal Transit of Guinea Pig

BACKGROUND/AIMS: A selective 5-hydroxytryptamine (5-HT) type 3 receptor antagonist, ramosetron, inhibits stress-induced abnormal defecation in animals and is currently used as a therapeutic drug for irritable bowel syndrome with diarrhea. The aim of this study is to investigate the effect of ramosetron on altered gastrointestinal (GI) transit. METHODS: Male guinea pigs weighing approximately 300 g were used. The effect of ramosetron was investigated on altered GI transit induced by thyrotropin-releasing hormone (TRH), 5-HT, or mustard oil (MO). GI transit was evaluated by the migration of charcoal mixture from the pylorus to the most distal point, and expressed as a percentage (%) of charcoal migration (cm) of the total length of total small intestine (cm). RESULTS: The average charcoal transit was 51.3 +/- 20.1% in the control (vehicle) group, whereas in the ramosetron group charcoal moved 56.6 +/- 21.9%, 46.9 +/- 9.14% and 8.4 +/- 5.6% of the total small intestine at the concentrations of 10, 30 and 100 microg/kg, respectively. GI transit after administration of TRH (100 microg/kg), 5-HT (10 mg/kg) or MO (10 mg/kg) was accelerated compared to vehicle (5-HT, 94.9 +/- 9.22%; TRH, 73.4 +/- 14.7%; MO, 81.0 +/- 13.7%). Ramosetron inhibited GI transit altered by 5-HT, TRH or MO. CONCLUSIONS: Ramosetron modulated GI transit. We suggest that ramosetron may be therapeutically useful for those with accelerated upper GI transit.

Sex identification from cranial capacity of adult human skulls.

Cranial capacity constitutes one of the most important characters for determining the racial differences. However, few studies exist that have evaluated the sexual dimorphism of cranial capacity and its significance in determining the sex of an individual. A craniometric study was conducted to differentiate sex from intracranial volumes of dry human skulls. The study was done on 160 dry human skulls (100 males and 60 females) in the department of forensic medicine, Gandhi Medical College, Bhopal (M.P.), during the year 2005 – 2006. Skulls chosen for the present study were of adult age only. Dry, hard mustard seed of uniform size were used to fill the cranial cavity to determine the capacity. Mean cranial capacity of male skulls was found to be 1302.95 + 108.8 c.c. (range 1070 – 1560 c.c.), while in female skulls the mean cranial capacity was found 1179.92 + 97.08 c.c. (range 1000 – 1420 c.c.). A highly significant difference (p value <0.01) was observed between the intracranial volume of male and female skulls were compared. This data is expected to be of Clinical, Forensic, Anthropological and Genetic Importance

[Study of antibacterial effects of hydro - alcoholic extract of 8 medicinal herbs against vancomycin resistant Staphylococcus aureus]

Staphylococcus aureus is one of the leading bacterial species causing infection in human. This species is or becoming resistant to many antibiotics, including vancomycin. As vancomycin is one of the antibiotics used as a last resort for the treatment of the infections caused by S. aureus, therefore identification and application of new effective antibacterial compounds is of utmost importance. In this study, the anti VRSA effects of the hydro alcoholic extracts of 8 Iranian medicinal plants including bulb of Allium ascalonicum, Allium sativum, leave of Utica dioica, Falcaria vulgari, Achillea millefolium and Trigonella foenum and seeds of Trigonella foenum and Brassica alba were surveyed. The effects were studied using disk diffusion method and the Minimum Inhibitory Concentration was determined using micro dilution broth methods against 15 VRSA strains. Among the extracts, the most effective was Allium ascalonicum bulb: MIC 50: 128 micro g/ml and Achillea millefolium had the least effect: MIC 50: 1000 micro g/ml. As VRSA strains are widespread in the world and treatment of the causative infections is becoming a major problem in medicine, these results, especially results of anti VRSA effects of Allium ascalonicum bulb extract, might be very helpful but clinical application of these extracts and identification of the fractions need further study
