A group of Chinese plant ge-neticists recently succeededin ferreting out a functionalgene responsible for rice tillering,demystifying a long-standing puzzlein crop growth.Tillering is a special branchingprocess in a cereal crops earlygrowth in which numerous shootsput forth almost at the same timefrom the main stem. The crop yield,when harvested afterwards, is al-ways hinged on the number of thesprouting shoots. So the process be-comes an agronomic trait of vital im-portance in the production …  相似文献

Diabetes mellitus and thyroid disorders are common endocrinopathies, which often occur parallel. Dyslipidemia is very common in both of these conditions. The development of hypothyroidism is well-known in type 1 diabetics, but it was not distinctly understood in type 2 diabetics. Thus we tried to examine the association between type II deiodinase (D2 or DIO2) Thr92Ala single nucleotide gene polymorphism and thyroid function among type 2 diabetes mellitus patients. A total of 130 type 2 diabetics were screened and genotyped for DIO2 Thr92Ala polymorphism. Fasting plasma glucose, Glycosylated haemoglobin, lipid and thyroid profiles, malondialdehyde (MDA) and paraoxonase were estimated according to standard procedures. A significant altered level of thyroid hormones (TH’s) was found in Ala/Ala genotype when compared with Thr/Thr or Thr/Ala genotype. DIO2 and T3:T4 ratio significantly decreased, whereas total T4 and thyroid stimulating hormone levels significantly elevated among Ala/Ala genotype (131 ± 30 ng/ml; 0.12 ± 0.05; 7.17 ± 2.05 µg/dl; 4.77 ± 3.1 µIU/ml, respectively) when compared with Thr/Thr + Thr/Ala genotypes (176 ± 33 ng/ml; 0.21 ± 0.05; 5.21 ± 1.1 µg/dl; 2.59 ± 1.61 µIU/ml respectively). Moreover, D2 levels were significantly negatively correlated with TH’s levels except total T4 among Ala/Ala genotypes. All the patients were having a poor glycemic control, and their glycemic status was positively correlating with MDA levels. On the other hand, serum paraoxonase activity decreased among Ala/Ala genotype (104 ± 21 vs. 118 ± 18 nmol/min/ml). In conclusion, DIO2 Ala92 homozygous variant found to be associated with altered levels of DIO2, Thyroid profile and paraoxonase. Hence, we recommend to do detail study of genetic factors related to thyroid function and prevent additional diabetic complications.  相似文献

Diabetes mellitus (DM) is one of the most prevalent diseases in the world, which is strongly associated with liver dysfunction. Hyperglycemia, through an oxidative stress pathway, damages various tissues. Herbal medicine is a good candidate to ameliorate hyperglycemia and oxidative stress. In this study, the effects of aqueous Allium sativum (garlic) extract (AGE) on gene expression of inducible nitric oxide synthases (iNOS) and production of nitric oxide (NO) were evaluated in the liver tissue of diabetic rats. Four groups of rats contained normal control rats, garlic control rats (AGE), Streptozotocin (STZ) + nicotinamide-induced diabetic rats (DM), and diabetic rats treated with garlic (DM + AGE). Glucose levels and liver enzymes activities were determined by colorimetric assay in the serum. Gene expression of iNOS by real-time PCR, NO levels by Griess method, oxidative stress parameters by spectrophotometric method and histopathological examination by hematoxylin and eosin staining method were evaluated in the liver tissues. Glucose levels, activities of liver enzymes, oxidative stress markers, iNOS gene expression, and NO production increased significantly in diabetic rats in comparison with control rats, whereas after oral administration of garlic, these parameters decreased significantly, close to the normal levels. Hence, the beneficial effects of garlic on the liver injury of diabetes could be included in the hypoglycaemic and antioxidant properties of garlic via a decrease in gene expression of iNOS and subsequent NO production.  相似文献

Cystic Fibrosis Trans membrane conductance regulator (CFTR) gene is an asthma susceptibility gene. In the present study we investigated the possible association of CFTR gene mutations in Indian asthmatic children as compared to controls. The study included 250 asthmatics and 250 age and sex matched controls. Case to control ratio for sample size was 1:1. Genotyping was performed for 24 CFTR gene mutations by ARMS-PCR and PCR–RFLP method. Among 24 CFTR gene mutations, heterozygous allele of R553X mutation was found in 4 (1.6 %) asthmatic cases and 2 (0.8 %) controls. Value of FVC and FEV1/FVC ratio were significantly lower in heterozygous individuals (p value <0.05). No significant difference was observed in the genotype and allele frequency of R553X mutation (OR = 1.339, 95 % CI = 0.755–2.374, p value = 0.685). Furthermore, all wild type homozygous alleles were observed in remaining 23 CFTR gene mutations. Our data concludes that R553X mutation was not significantly associated in Indian asthmatic children.  相似文献

On 27 October 2001, the Standing Committee of the People's Congress reviewed and passed the Amendment to the Copyright Law of the People's Republic of China. In Article 10 of the amended Copyright Law as of 2001 has been incorporated a new subject matter under the copyright protection: the right of communication through information network, that is, the right to make a work available to the public by wire or by wireless means, so that people may have access to the work from a place and at a time individually chosen by them. This is the first time to have put the right of communication through information network in place in the law in China. But, the legislators did not make any specific provisions concerning this right in the Copyright Law.  相似文献

Matrix metalloproteinase [MMP]-2 and tissue inhibitor of metalloproteinase [TIMP]-2 are emerging as pivotal players in inflammation and carcinogenesis. The present study aimed to evaluate the role of MMP-2 (−735C > T) [rs 2285053] and TIMP-2 (−418G > C) [rs 8179090] gene polymorphisms in cervical cancer susceptibility in Indian women. We recruited 200 cervical cancer patients from North India and 200 unrelated, age-matched, cancer-free healthy female controls of similar ethnicity. Genomic DNA extraction from peripheral blood samples, collected from the study subjects, was carried out using salting-out method. MMP-2 and TIMP-2 genotyping was performed using polymerase chain reaction-based restriction fragment length polymorphism. Our findings demonstrated no significant association between MMP-2 (−735C > T) and TIMP-2 (−418G > C) gene polymorphisms and the risk of developing cervical cancer in the study population. Further stratified analysis using a case-only study approach revealed that there was no effect of MMP-2/TIMP-2 polymorphisms on early and advanced stages of cervical cancer. Further MMP-2 and TIMP-2 polymorphisms did not modulate the risk in cervical cancer patients who smoked tobacco/cigarettes. Overall, the present study demonstrated a lack of association between MMP-2 and TIMP-2 gene polymorphisms and cervical cancer susceptibility in women of Northern India.  相似文献

Graves’ disease (GD) is an organ-specific heterogenous autoimmune disorder associated with T-lymphocyte abnormality affecting the thyroid, eyes and skin. GD is a multifactorial disease that develops as a result of complex interaction between genetic susceptibility genes and environmental factors. It has been suggested that the Cytotoxic T lymphocytes associated molecule-4 (CTLA-4) is a genetic susceptibility candidate for GD. The present study was focused on A/G polymorphism at position 49 in exon-1 of the CTLA-4 gene in 80 GD patients (GP) and 80 sex and age matched healthy individuals among South Indian (Madurai) population. Serum concentrations of thyroid hormone (T4, T3 and TSH) were determined by using automated analyzer. The genomic DNA was isolated from the patient and control groups and genotyping was performed using the polymerase chain reaction followed by restriction enzyme analysis using Bbv1. Significant difference (P < 0.001) was observed in the level of T3, T4 and TSH in GD patients and healthy individuals. The results revealed the CTLA-4 gene G/G genotype to be 32 (40%) in patients and 26 (32.50%) in healthy individuals, A/G genotype to be 37 (46.25%) in patients and 25 (31.25%) in healthy individuals and A/A genotype to be 11 (13.75%) in patients and 29 (36.25%) in healthy individuals. The calculated odds ratio (OR) in individuals with mutant genotype (GG/AG) reveal 3.6 fold risk for GD (95% confidence interval = 1.6–7.8). The mutant “G” allele frequency was observed to be 0.63 in GD patients and 0.48 in healthy individuals. Thus the present study demonstrates an association between the CTLA-4 gene polymorphism and Graves’ disease.  相似文献
