Spliced leader (SL) trans-splicing is a biological phenomenon, common among many metazoan taxa, consisting in the transfer of a short leader sequence from a small SL RNA to the 5′ end of a subset of pre-mRNAs. While knowledge of the biochemical mechanisms driving this process has accumulated over the years, the functional consequences of such post-transcriptional event at the organismal level remain...
Long intergenic non-coding RNAs (lincRNAs) are a new type of non-coding RNAs and are closely related with the occurrence and development of diseases. In previous studies, most lincRNAs have been identified through next-generation sequencing. Because lincRNAs exhibit tissue-specific expression, the reproducibility of lincRNA discovery in different studies is very poor. In this study, not including...
Two fatty acid desaturase genes have been cloned: HpFAD2 and HpFAD3 encode Hansenula polymorpha Δ12-fatty acid desaturase (HpFad2) and Δ15-fatty acid desaturase (HpFad3), which are responsible for the production of linoleic acid (LA, C18:2, Δ9, Δ12) and α-linolenic acid (ALA, αC18:3, Δ9, Δ12, Δ15), respectively. The open reading frame of the HpFAD2 and HpFAD3 genes is 1215bp and 1239bp, encoding 405...
High titers of anti-citrullinated protein/peptide antibodies (ACPAs) have been detected in sera of rheumatoid arthritis (RA) patients, implicating citrullinating enzymes in the pathogenesis of RA. Peptidylarginine deiminase type IV (PAD4) is a member of the PAD family of citrullinating enzymes and has been linked to RA. Therefore, our aim was to determine how transcription of PAD4 is regulated in...
Frizzleds (FZDs) are transmembrane receptors in the Wnt signaling pathway and they play pivotal roles in developments. The Frizzled-like extracellular Cysteine-rich domain (Fz-CRD) has been identified in FZDs and other proteins. The origin and evolution of these proteins with Fz-CRD is the main interest of this study. We found that the Fz-CRD exists in FZD, SFRP, RTK, MFRP, CPZ, CORIN, COL18A1 and...
One particularly interesting single nucleotide polymorphism (SNP), rs6235 (encoding an S690T substitution), in the proprotein convertase subtilisin/kexin type 1 (PCSK1) gene has been widely associated with obesity in several European cohorts. The present study was intended to investigate the association between the PCSK1 rs6235 SNP and the prevalence of overweight or obesity, or obesity-related metabolic...
Low levels of vitamin D are implicated as a potential risk factor for prostate cancer, and the vitamin D receptor (VDR) gene may be important in the onset and progression of prostate cancer. In this study, sequence variants in the VDR gene were investigated in a Korean study cohort to determine whether they are associated with prostate cancer risk. We evaluated the association between 47 single nucleotide...
Mesenchymal stem cells (MSCs) possess a multi-lineage differentiation capacity that makes them important players in the field of regenerative medicine. MSC populations derived from different tissues or donors have been shown to exhibit variable gene expression patterns. Further, it is widely acknowledged that MSC isolates are heterogeneous mixtures of cells at different developmental stages. However,...
There are no data regarding the possible role of the single nucleotide polymorphism (SNP) of class I histone deacetylases (HDACs) in type 2 diabetes mellitus (DM). We designed this study to examine whether polymorphisms of HDACs can be implicated in that disease.A community-based, case–control study was conducted, with a total of 568 subjects (284 patients and 284 controls) enrolled. Four polymorphisms...
Current viral gene delivery vectors for gene therapy are inefficient due to short-lived transgene expression attributed to the cytosine-phosphate-guanine (CpG) motifs in the transgene. Here we assessed the effects of CpG motif reduction in lentiviral (LV) gene delivery context on the level and duration of reporter gene expression in Chinese Hamster Ovary (CHO) cells, Human Immortalized Myelogenous...
The complete 15,223-bp mitochondrial genome (mitogenome) of Tryporyza incertulas (Walker) (Lepidoptera: Pyraloidea: Crambidae) was determined, characterized and compared with seven other species of superfamily Pyraloidea. The order of 37 genes was typical of insect mitochondrial DNA sequences described to date. Compared with other moths of Pyraloidea, the A+T biased (77.0%) of T. incertulas was the...
Oculocutaneous Albinism (OCA) is a heterogeneous group of inherited diseases involving hair, skin and eyes. To date, six forms are recognized on the effects of different melanogenesis genes.OCA4 is caused by mutations in SLC45A2 showing a heterogeneous phenotype ranging from white hair, blue irides and nystagmus to brown/black hair, brown irides and no nystagmus. The high clinic variety often leads...
To investigate the response of Plutella xylostella transcriptome in defending against a Bt toxin, high-throughput RNA-sequencing was carried out to examine Cry1Ac-susceptible and -resistant strains. The comparative analysis indentified over 2900 differentially expressed unigenes (DEUs) between these two strains. Gene Ontology analysis placed these unigenes primarily into cell, cell part, organelle,...
Drought is one of the most severe threats to the growth, development and yield of plant. In order to unravel the molecular basis underlying the high tolerance of pitaya (Hylocereus undatus) to drought stress, suppression subtractive hybridization (SSH) and cDNA microarray approaches were firstly combined to identify the potential important or novel genes involved in the plant responses to drought...
Identifying susceptibility genes that influence complex diseases is extremely difficult because loci often influence the disease state through genetic interactions. Numerous approaches to detect disease-associated SNP-SNP interactions have been developed, but none consistently generates high-quality results under different disease scenarios. Using summarizing techniques to combine a number of existing...
Panax notoginseng (Burk) F. H. Chen, an economically significant medicinal plant with hemostatic and health tonic activities, has been used in Traditional Chinese Medicine (TCM) for more than 3000years. Triterpene saponins are responsible for most of the pharmacological activities of P. notoginseng. Here, we cloned five cDNA sequences encoding the key enzymes involved in triterpene saponin biosynthesis,...
BC1 is a short non-coding RNA from rodents, which is transcribed by RNA pol III. Its RNA is highly abundant in the brain, where it exerts a post-transcriptional regulatory role in dendrites. Upon transcription, retroposition and insertion, BC1 gives rise to a subclass of short interspersed repetitive sequences (SINEs) named identifier (ID) elements. IDs can become integrated inside non-coding regions...
A mature miRNA may be generated from 5p or 3p arm of a hairpin precursor. The selection may be flexible via “arm switching”. However, accumulating evidences suggest that both arms of many pre-miRNAs can yield mature functional miRNAs. Herein, we attempted to compare the isomiR expression profiles between the two arms through analyzing in-house and published small RNA deep sequencing datasets. Although...
In osteoblasts, Integrin-Linked Kinase (ILK)-dependent phosphorylation of the cJUN transcriptional coactivator, αNAC, induces the nuclear accumulation of the coactivator and potentiates cJUN-dependent transcription. Mutation of the ILK phosphoacceptor site within the αNAC protein leads to cytoplasmic retention of the coactivator and cell-autonomous increases in osteoblastic activity. In order to gain...
