Cyclin D1; Multiple myeloma; Single nucleotide polymorphism

Cyclin D1 is an important cell cycle regulator implicated in the pathogenesis of many cancer types. In particular, translocation and overexpression of cyclin D1 are common events in multiple myeloma (MM), suggesting that it may drive the initiation and progression of this malignancy. However, the association between genetic polymorphisms of cyclin D1 and the risk for developing MM remains ... more

Growth trait; IGF-1 gene; SNP; Tibetan miniature pig

The IGF-1 gene is an important regulating factor that has a growth-promoting effect on growth hormone. The IGF-1 gene promotes muscle cell differentiation in the muscle cell formation process. The IGF-1 gene also regulates the growth of skeletal muscle during skeletal muscle growth. In addition, the IGF-1 gene plays an important role in the formation of mammals and poultry embryos, and ... more

GFI1B gene; Growth trait; Indigenous Chinese goats; PCR-RFLP; PCR-SSCP

This study aimed to investigate polymorphisms of the eighth exon in the GFI1B gene among three indigenous Chinese goat breeds (QianBei Ma goats, GuiZhou white goats, and GuiZhou black goats). Furthermore, association analysis was conducted between these polymorphisms and growth traits. Polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP), direct DNA ... more

Carcass composition trait; Cattle; Growth trait; Meat quality trait; Polymorphism; Thyroglobulin gene

Thyroid hormones play an important role in regulating metabolism and can affect metabolism-related traits such as fat deposition. The thyroglobulin (TG) gene produces the precursor of thyroid hormones and has been proposed as a candidate gene for a quantitative trait locus with an effect on fat deposition. In this study, we identified 4 novel single nucleotide polymorphisms (SNPs ... more

Multidrug resistance; multidrug resistance protein; Single nucleotide polymorphism

One of the main problems in treating cancer patients is that cancer cells can develop drug resistance. Resistance to multiple anticancer drugs, so called multidrug resistance (MDR), most likely involves a nonspecific mode of resistance, through drug-efflux transporters. One of the most extensively studied genes involved in MDR is multidrug resistance protein 1 (MRP1). We investigated ... more

Carcass traits; quantitative trait locus; Single nucleotide polymorphism; Sus scrofa chromosome 7 (SSC7)

Many QTLs for fatness traits have been mapped on pig chromosome 7q1.1-1.4 in various pig resource populations. Eight novel markers, including seven SNPs and one insertion or deletion within BTNL1, COL21A1, PPARD, GLP1R, MDFI, GNMT, ABCC10, and PLA2G7 genes, as well as two previously reported SNPs in SLC39A7 and ... more

Allelic frequencies; meat quality; Myogenic determination gene 1; Qinchuan cattle; Single nucleotide polymorphism

The myogenic determination 1 (MyoD1) gene is a member of the MyoD gene family. It encodes for skeletal muscle-specific transcription factors containing highly conserved basic helix-loop-helix regions that perform important roles in the initiation, maintenance, and regulation of phenotypic traits. We investigated a new single nucleotide polymorphism (SNP) in the MyoD1 gene to evaluate ... more

Dairy cattle; Fertility; Growth hormone; IGF-1; Single nucleotide polymorphism

The somatotrophic axis (GH-IGF) is a key regulator of animal growth and development, affecting performance traits that include milk production, growth rate, body composition, and fertility. The aim of this study was to quantify the association of previously identified SNPs in bovine growth hormone (GH1) and insulin-like growth factor 1 (IGF-1) genes with direct ... more

Cathechol-o-methyltransferase; Dopamine D3 receptor; Polymerase chain reaction; Restriction fragment length polymorphism; Schizophrenia; Single nucleotide polymorphism

Molecular components of the dopamine D3 receptor (DRD3) may play an important role in the pathophysiology of schizophrenia. Previous studies have demonstrated an association between DRD3 Ser9Gly and cathechol-o-methyltransferase (COMT, SNP = rs165656) polymorphisms and schizophrenia but the results were inconclusive. We investigated this apparent association between Ser9Gly (A/G) ... more

Essential hypertension; Mongolian population; Single nucleotide polymorphism; TSC

We investigated a possible association between genetic variations in the thiazide-sensitive Na-Cl cotransporter (TSC) gene and essential hypertension (EH) in the Mongolian and Han ethnic groups in Inner Mongolia. Our study included 385 unrelated Mongolian herdsmen and 523 Han farmers. Nine tagSNPs of TSC were identified from the Chinese HapMap database based on pairwise ... more
