FSH is a glycoprotein hormone secreted by the pituitary gland that is essential for gonadal development and reproductive function. In avian reproduction study, especially in avian reproduction hormone study, it is hindered by the lack of biologically active FSH. In order to overcome this shortcoming, we prepared recombinant goose FSH as a single chain molecule and tested its biological activities in the present study. Coding sequences for mature peptides of goose FSH α and β subunits were amplified from goose pituitary cDNA...

Polygenic diseases with a broad phenotypic spectrum, such as polycystic ovary syndrome (PCOS), present a particular challenge in terms of identifying the underlying genetic mechanisms, nevertheless genetic variants have impact on the individual phenotype. We aimed to determine if next to genetic variations like SNPs further mechanisms might play a role in the pathogenesis of PCOS. We examined the effect of copy-number variations (CNVs) on metabolic phenotypes in PCOS. The intragenic rs1244979, rs2815752 in NEGR1 gene, and rs780094 in GCKR gene were genotyped and CNVs were determined by droplet digital polymerase chain reaction (ddPCR) in PCOS patients (n = 153) and controls without metabolic syndrome (n = 142)...

A number of members of the SAP ("stress-associated protein") gene family have been implicated in the plant stress response. Here, a SAP gene has been isolated using PCR RACE from the perennial grass Leymus chinensis, a species which has reputation for ecological adaptability. The 17.6 kDa LcSAP product comprised 161 residues, including both an A20 domain and an AN1 domain, a feature of type I SAPs. Using a semi-quantitative RT-PCR assay to profile its transcription, it was shown that LcSAP was more strongly transcribed in the leaf than in the root under control conditions...

Two homologous genes, Brassica campestris Male Fertility 23a (BcMF23a) and Brassica campestris Male Fertility 23b (BcMF23b), encoding putative pectin methylesterases (PMEs) were isolated from Brassica campestris ssp. chinensis (syn. Brassica rapa ssp. chinensis). These two genes sharing high sequence identity with each other were highly expressed in the fertile flower buds but silenced in the sterile ones of genic male sterile line system ('Bcajh97-01A/B'). Results of RT-PCR and in situ hybridization suggested that BcMF23a and BcMF23b were pollen-expressed genes, whose transcripts were first detected at the binucleate pollen and maintained throughout to the mature pollen grains...

Various case-control studies have shown association of single nucleotide polymorphism rs12303764(G/T) in ULK1 with crohn's disease. The techniques used in these studies were time consuming, complicated and require sophisticated/expensive instruments. Therefore, in order to overcome these problems, we have developed a new, rapid and cost effective Tetra-primer ARMS-PCR assay to genotype single nucleotide polymorphism rs12303764(G/T) of ULK1 gene. We manually designed allele specific primers. DNA fragment amplified using outer primers was sequenced to obtain samples with known genotypes (GG, GT and TT) for further use in the development of T-ARMS-PCR assay...

The mycobacterial insertion sequence IS6110 proved crucial in deciphering tuberculosis (TB) transmission dynamics. This sequence was also shown to play an important role in the pathogenicity (transmission ability and/or virulence) of Mycobacterium tuberculosis, the main causative agent of TB in humans. In this study, we explored the usefulness of IS6110 and its potential as a phylogenetic/typing marker. We also analyzed the genetic polymorphism and evolutionary trends (selective pressure) of its transposase-encoding open reading frames (ORFs), A and B, using the maximum likelihood method...

The extraction of genomic DNA is the crucial first step in large-scale epidemiological studies. Though there are many popular DNA isolation methods from human whole blood, only a few reports have compared their efficiencies using both end-point and real-time PCR assays. Genomic DNA was extracted from coronary artery disease patients using solution-based conventional protocols such as the phenol-chloroform/proteinase-K method and a non-phenolic non-enzymatic Rapid-Method, which were evaluated and compared vis-a-vis a commercially available silica column-based Blood DNA isolation kit...

The mitotic arrest deficiency 2 (Mad2) protein is an essential component of the spindle assembly checkpoint that interacts with Cdc20/Slp1 and inhibit its ability to activate anaphase promoting complex/cyclosome (APC/C). In bladder cancer cell line the C-terminal residue of the mad2 gene has been found to be deleted. In this study we tried to understand the role of the C-terminal region of mad2 on the spindle checkpoint function. To envisage the role of C-terminal region of Mad2, we truncated 25 residues of Mad2 C-terminal region in fission yeast S...
