Advancement in genome sequencing and in silico mining tools have provided new opportunities for comparative primate genomics of microsatellites. The SSRs (simple sequence repeats) numbers were not correlated with the genome size (Pearson, r=0.310, p=0.550), and were positively correlated with the total length of SSRs (Pearson, r=0.992, p=0.00). A total of 224,289 tetranucleotide orthologous microsatellites...
Efforts have been made to characterize the high-altitude adaption in Tibetan pigs and identified vast of genes or genomic regions undergone natural selection. Nonetheless, information concerning gene expression and DNA methylation changes response to low-altitude acclimation in Tibetan pigs is long overdue. To explore the exceptional mechanisms of gene expression and DNA methylation that are induced...
Flavin-containing monooxygenase 3 (FMO3) plays a critical role in catalyzing the conversion of trimethylamine (TMA) to trimethylamine-N-oxide (TMAO) in vivo. Despite the well-documented association between FMO3 mutations and a ‘fishy’ off-flavor eggs in chicken and quail, little information is available regarding the molecular characteristic of goose (Anser cygnoides) FMO3 and its relationship with...
Microsatellite studies based on chromosomes level would contribute to the biometric correlation analysis of chromosome and microsatellite applications on the specific chromosome. In this study, the total microsatellite length of 1,141,024 loci was 21.8Mb, which covered about 0.74% of the male Rhesus monkey genome. Perfect mononucleotide SSRs were the most abundant, followed by the pattern: perfect...
Flammulina velutipes is one of the most widely cultivated mushroom species in China. However, its genetic background remains poorly understood due to the limited sampling and poor molecular markers used. In this study, 124 F. velutipes strains were employed, including 110 cultivars and 14 wild strains, and 25 new SSR markers were developed based on the genome of F. velutipes. A total of 153 alleles...
Laryngeal squamous cell carcinoma (LSCC) is a common malignant tumor of the otolaryngeal region and accounts for 1–2% of all malignancies diagnosed worldwide. miR-340 down-regulation and EZH2 up-regulation have been frequently identified in multiple cancers, but the role of miR-340 and EZH2 in LSCC has not been explored. In this study, we investigated the regulative role of miR-340 in EZH2 expression...
In this study, we aimed to assess the neuroprotective effect of sevoflurane preconditioning in a cerebral focal ischemia–reperfusion rat model. Sixty Sprague Dawley rats were divided into six groups: sham operated group, cerebral focal ischemia–reperfusion (CIR) group, CIR+sevoflurane preconditioning (SP) (2%) group, CIR+sevoflurane preconditioning (2.5%) group, CIR+sevoflurane preconditioning (3%)...
Plant microRNAs (miRNAs) play important roles as modulators of gene expression at the post-transcriptional level. Previous studies have shown that high-throughput sequencing is a powerful tool for the identification of miRNAs, and it is believed that many more miRNAs remain to be discovered. Here, we found 23 novel conserved miRNAs from three rice cultivars by high-throughput sequencing and further...
Because the molecular mechanisms underlying the development of laryngeal cancer are not well understood, we conducted a case–control study to determine the association between eight common SNPs in NER pathway genes and risk of laryngeal cancer, and the association between genetic polymorphisms and environmental factors. A 1:1 matched case–control study of 176 cases and 176 controls was conducted....
MicroRNAs (miRNAs) are a class of non-coding RNAs known to play important regulatory roles through targets, which can affect human cell proliferation, differentiation, and metabolism. Overlaps between different miRNA target prediction algorithms (MTPAs) are small, which limit the understanding of miRNA's biological functions. However, the overlaps increase on functional levels, such as Gene Ontology...
The HD-Zip proteins comprise one of the largest families of transcription factors in plants. HD-Zip genes have been grouped into four different classes: HD-Zip I to IV. In this study, we described the identification and structural characterization of Class I HD-Zip genes in cucumber. A complete set of 13 HD-Zip I genes were identified in the cucumber genome using Blast search tools and phylogeny....
Anthracnose caused by Colletotrichum spp. is one of the most destructive diseases of cultivated strawberry (Fragaria×ananassa Duchesne) worldwide. The correlation between NBS–LRR genes, the largest class of known resistance genes, and strawberry anthracnose resistance has been elusive. BLAST search in NCBI identified 94 FvNBSs in the diploid genome of strawberry Fragaria vesca, with 67 of the TIR–NBS–LRR...
There is more evidence that interleukin-10 (IL-10), as a multifunctional regulatory cytokine of inflammatory responses, may have an important role in type 2 diabetes (T2D). However, genetic association studies that evaluated the relationship between IL-10 gene variants and T2D have produced conflicting results. The aim of this study was to determine whether the IL-10 gene polymorphisms (−592A/C, −1082G/A,...
Most methods for genome-wide association studies (GWAS) focus on discovering a single genetic variant, but the pathogenesis of complex diseases is thought to arise from the joint effect of multiple genetic variants. Information about pathway structure, such as the interactions and distances between gene products within pathways, can help us learn more about the functions and joint effect of genes...
Chicken repeat 1 (CR1) elements, a class of retroposons belonging to non-long-terminal repeats, have been recognized as powerful tools for phylogenetic studies. Here we examine the phylogenetic relationships of 11 Phasianidae species based on CR1 retroposons. Together with 19 loci reported previously, a total of 99 CR1 loci were identified from chicken genome and turkey BAC clone sequences. 75 insertion...
Plant resistance genes (R-genes) evolve rapidly in response to changing environments. What are the most remarkable signatures of fast adaptive genes, besides the commonly revealed rapid divergence and high non-synonymous substitution rate? Here we investigated these changes in five R-loci following recent differentiation between Arabidopsis thaliana and Arabidopsis lyrata. Extreme differences in evolutionary...
Genus Macaca (Cercopithecidae: Papionini) is one of the most successful primate radiations. Despite previous studies on morphology and mitochondrial DNA analysis, a number of issues regarding the details of macaque evolution remain unsolved. Alu elements are a class of non-autonomous retroposons belonging to short interspersed elements that are specific to the primate lineage. Because retroposon insertions...
The complete sequence of the mitochondrial genome of the Sichuan Hill Partridge (Arborophila rufipectus) has been determined by long and accurate polymerase chain reaction (LA-PCR) and with primer walking sequence method. The genome is 16728 bp in size, containing 2 ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA (tRNA) genes and one control region, demonstrating a structure very similar...
