Adiponectin, a protein exclusively secreted by adipose tissue and present at low levels in obese individuals, is now widely recognized as a key determinant of insulin sensitivity and protection against obesity-associated metabolic syndrome. In Jordan, prevalence of diabetes (17.1%) is twice that of the United States (7.8%). In this study, we examined the contribution of the promoter variant rs266729...
The prevalence of obesity has increased dramatically during the last thirty years in western countries with severe complications for health and economy. Obesity is the outcome of the strong interplay between genetic and environmental factors and is therefore widely expected that the discovery of the many genetic factors underlying the heritable risk of obesity will contribute critically to our basic...
The glioma-associated oncogene family zinc finger 3 gene (GLI3) mediates in all vertebrates hedgehog (Hh) signaling that plays an essential role in the induction and patterning of numerous cell types during invertebrate and vertebrate development. In this study, a total of 6 single nucleotide polymorphisms (SNPs: 1–6) were identified by polymerase chain reaction–single stranded conformational polymorphism...
Vitamin B 12 is an essential micronutrient synthesized by microorganisms. Mammals including humans have evolved ways for transport and absorption of this vitamin. Deficiency of vitamin B 12 (either due to low intake or polymorphism in genes involved in absorption and intracellular transport of this vitamin) has been associated with various complex diseases. Genome-wide association...
Structural changes in different parts of the brain in rheumatoid arthritis (RA) patients have been reported. RA is not regarded as a brain disease. Body organs such as spleen and lung produce RA-relevant genes. We hypothesized that the structural changes in the brain are caused by changes of gene expression in body organs. Changes in different parts of the brain may be affected by altered gene expressions...
Meningioma is the second most common primary tumor of the central nervous system, and multiple genetic and environmental factors contribute to its etiology. Methylene tetrahydrofolate reductase (MTHFR) is a pivotal enzyme in folate metabolism. We conducted a case–control study to investigate the association of the MTHFR gene and meningioma in a Han population in northern China.We genotyped two SNPs...
Keratin-associated proteins (KAPs) are among the main structural components of the animal fibers and form semi-rigid matrix wherein the keratin intermediate filaments (KIFs) are embedded. Variation in the KAP genes has been reported to affect the structure of KAPs and hence fiber characteristics. As no information is available on this gene in Capra hircus therefore, present work was undertaken to...
The cysteine and glycine-rich protein 1 and 2 genes (CSRP1 and CSRP2) are an effective growth factor in promoting skeletal muscle growth in vitro and vivo. However, in cattle, the information on the CSRP1 and CSRP2 genes is very limited. The aim of this study was to examine the association of the CSRP1 and CSRP2 variants with growth and carcass traits in cattle breeds. Three single nucleotide variants...
Wnt7a is a member of the WNT gene family, which encodes secreted signaling proteins and responds to many biological processes. Specifically Wnt7a influences satellite stem cells and regulates the regenerative potential of the muscle. However, similar researches about the bovine Wnt7a gene are lacking. Therefore, in this study, polymorphisms of the bovine Wnt7a gene were detected in 488 individuals...
The effect of ABCB1 C3435T SNP on the pharmacokinetics of immunosuppressive drug tacrolimus in different studies was conflicting. So a meta-analysis was employed to study the correlation of ABCB1 C3435T SNP and the pharmacokinetics of tacrolimus at different post-transplantation times.Several studies about ABCB1 C3435T polymorphism and the pharmacokinetics of tacrolimus were collected through the...
Apolipoprotein A-II (APOA2) is one of the major constituents of high-density lipoprotein and plays a critical role in lipid metabolism and obesity. However, similar research for the bovine APOA2 gene is lacking. In this study, polymorphisms of the bovine APOA2 gene and its promoter region were detected in 1021 cows from four breeds by sequencing and PCR-RFLP methods. Totally, we detected six novel...
The PROP1 protein, encoded by the prophet of Pit-1 (PROP1) gene, exhibits both DNA-binding and transcriptional activation abilities. Its expression leads to the ontogenesis of growth hormone (GH), prolactin (PRL), thyroid-stimulating hormone (TSH), and pituitary hormone. The missense mutation H173R in PROP1 may result in deficiencies of GH, PRL, TSH, and Pit-1, thereby affecting growth traits. The...
The paired-like homeodomain transcription factor 2 (PITX2) gene plays a critical role in cell proliferation, differentiation, hematopoiesis and organogenesis. This gene regulates several genes' expressions in the Wnt/beta-catenin and POU1F1 pathways, thereby probably affecting milk performance. The goal of this study was to characterize the genetic variants of the PITX2 gene and test their associations...
Here we report the association of the rs694539 variant of nicotinamide-N-methyltransferase gene with bipolar disorder in a case–control study of 95 bipolar disorder patients and 201 healthy controls (χ 2 =13.382, P=0.001). With the polymerase chain reaction restriction fragment length polymorphism method we developed we were able to show the association for the first time. This new finding...
Bone morphogenetic proteins (BMPs) are peptide growth factors belonging to the transforming growth factor-beta (TGF-β) superfamily, and some members of the BMP family support white adipocyte differentiation. In this study, we focused on the BMP7 which singularly promotes the differentiation of brown preadipocytes. Haplotypes involving 5 single nucleotide polymorphism (SNP) sites in the bovine BMP7...
