Amplified fragment length polymorphism; Genetic diversity; Jackfruit; Markers; Polymorphism

Artocarpus heterophyllus Lam., commonly called jackfruit, is a medium-sized evergreen tree that bears high yields of the largest known edible fruit. Yet, it has been little explored commercially due to wide variation in fruit quality. The genetic diversity and genetic relatedness of 50 jackfruit accessions were studied using amplified fragment length polymorphism markers. Of 16 primer ... more

Breast cancer; Chemotherapy; P-glycoprotein; Polymorphism

Primary chemotherapy is a useful strategy for the treatment of locally advanced breast cancer and therefore allows in vivo evaluation of the action of cytotoxic drugs and the possibility of accomplishing conservative breast surgeries, as well as the early treatment of metastasis. Mechanisms of resistance to the drugs include the action of protein associated with the efflux of drugs from ... more

DNA methylation; Gossypium; introgression lines; Polymorphism

Introgression lines are some of the most important germplasm for breeding applications and other research conducted on cotton crops. The DNA methylation level among 10 introgression lines of cotton (Gossypium hirsutum) and three exotic parental species (G. arboreum, G. thurberi and G. barbadense) were assessed by methylation-sensitive amplified ... more

Addiction; Drugs; Heterochromatin; Leukemia; Polymorphism

Heterochromatin is considered to play a role in protecting the genome against mutagens. Changes in the quantity and proportion of different types of satellite DNA could increase genetic susceptibility in individuals with heterochromatic variations; they cause chromosome instability and predispose patients to malignancies. We evaluated the heterochromatin associated with chromosomes in 50 ... more

Glutathione S-transferase; Multiplex PCR; Polymorphism; Type-2 diabetes mellitus

Glutathione S-transferase (GST) protects cells against oxidative stress. We evaluated the effect of genetic polymorphisms of the GST gene family on the risk of developing type-2 diabetes mellitus and on glycemic control. We also investigated the effects of smoking combined with these polymorphisms on type-2 diabetes mellitus risk. We enrolled 100 type-2 diabetes mellitus patients and 100 ... more

Colorectal cancer; Meta-analysis; Polymorphism; VEGF

Vascular endothelial growth factor (VEGF) is an endothelial cell-specific mitogen involved in a number of pathologic processes, including angiogenesis, tumor growth and metastasis. Polymorphisms of the VEGF gene have been associated with susceptibility to colorectal cancer (CRC). However, the specific association still remains controversial. We made a meta-analysis of the association ... more

Breast cancer; CYP2C19; Genetics; Polymorphism

Cytochrome P450 (CYP) 2C19 metabolizes arachidonic acid to biologically active epoxyeicosatrienoic acids, which significantly promote proliferation of cancer cells in vitro and in vivo. We looked for a possible association between human CYP2C19*3 gene polymorphism and breast cancer in the Chinese Han population. In a Chinese Han case-control study of breast cancer ... more

FMF; Haplotype; MDR1; Polymorphism; Turkey

The multidrug resistance (MDR1) gene encodes a P-glycoprotein that plays a key role in drug bioavailability and response to drugs in different human populations. More than 50 SNPs have been described for the MDR1 gene. Familial Mediterranean fever (FMF) is considered an autosomal recessive hereditary disease, associated with a single gene named the Mediterranean fever gene (MEFV). However ... more

Alternative splicing variant; DRD2 gene; Expression; Pig; Polymorphism

The dopamine D2 receptor (DRD2) is a crucial mediator for normal physiological processes. We cloned the pig DRD2 gene, investigated its distribution in tissues and identified polymorphisms by RT-PCR, quantitative real-time PCR and direct sequencing. Two Yorkshire pigs from Guangdong Academy of Agricultural Sciences (Guangzhou, China) were selected to clone the gene and ... more

Head and neck cancer; Meta-analysis; Polymorphism; XPD

Several studies have investigated the association between Lys751Gln polymorphism in the xeroderma pigmentosum group D (XPD) gene and risk of head and neck cancer; however, the published results are conflicting. We conducted a meta-analysis that comprised 15 published case-control studies examining the association of head and neck cancer risk with XPD Lys751Gln ... more
