Growth-regulating factors (GRFs) are plant-specific transcription factors that have important functions in regulating plant growth and development. GRF gene families have been described in several plant species, but a comprehensive analysis of the GRF gene family in tobacco has not yet been reported. In this study, we identified 25 NtabGRF genes in N. tabacum. The gene structures, motifs, and cis-acting...
The sex of relatively primitive animals such as invertebrates is mostly determined by environmental factors and chromosome ploidy. Heteromorphic chromosomes may also play an important role, as in the ZW system in lepidopterans. However, the mechanisms of these various sex determination systems are still largely undefined. In the present study, a Masculinizer gene (Ar-Masc) was identified in the crustacean...
Cysteine-rich intestinal protein 1 (CRIP1) is an important transcriptional regulation factor during the tumor development. Although it was largely studied in the human or mouse, no report has provided functional evidence for it in the swine. To date, the real sequence of porcine CRIP1 (poCRIP1) was also still unknown. In this study, clear characteristics for the poCRIP1 were represented. A 552bp poCRIP1...
Recently, long noncoding RNAs (lncRNAs) have been emerged as crucial regulators of human diseases and prognostic markers in numerous of cancers, including colorectal carcinoma (CRC). Here, we identified an oncogenetic lncRNA HULC, which may promote colorectal tumorigenesis. HULC has been found to be up-regulated and acts as oncogene in gastric cancer and hepatocellular carcinoma, but its expression...
Dysfunction of vascular smooth muscle cells (VSMCs) performs a key role in the pathogenesis of diabetic vascular disease. Recent studies have reported that microRNA-24 (miR-24) may be implicated in diabetes and atherosclerotic vascular diseases. This study was designed to explore the role of miR-24 on VSMC proliferation and migration under high glucose conditions mimicking diabetes, and reveal the...
MicroRNAs (miRNAs) are implicated in the regulation of pathological and physiological processes in myocardial ischemia/reperfusion (MI/R). Recent studies have revealed that miR-22 might provide a potential cardioprotective effect on ischemic heart disease. However, the mechanism by which miR-22 prevents MI/R is still not fully clear. Here, we investigated the role of miR-22 in hypoxia/reoxygenation...
Most of the disease resistance genes already characterized in plants encode nucleotide-binding site–leucine rich repeat (NBS–LRR) proteins that have key roles in resistance to Verticillium dahliae. Using a cDNA library and RACE protocols, we cloned a coiled-coil (CC)–NBS–LRR-type gene, GbRVd, from a resistant tetraploid cotton species, Gossypium barbadense (RVd=Resistance to V. dahliae). We also applied...
Toll-like receptor 4 (TLR4) and its ligand high mobility group box 1 (HMGB1), are known for playing central roles in ischemia–reperfusion injury in myocardium. However, the detailed mechanisms of TLR4 and HMGB1 are not fully understood. The aim of this study was to investigate the effects and possible mechanisms of the HMGB1–TLR4 axis and cardiomyocyte apoptosis on myocardial ischemic damage. Artificial...
This study aimed to explore the role of high mobility box 1 (HMGB1) and its receptor toll like receptor 4 (TLR4) on neutrophils in myocardial ischemia reperfusion (I/R) injury. We constructed TLR4-mutant (C3H/HeJ) and control (C3H/HeN) mouse models of myocardial I/R injury and subjected the mice to 30min of ischemia and 6h of reperfusion. Light microscope was used to observe structural changes in...
Numerous matrix attachment regions (MARs) have been used to improve transgene expression in genetic engineering, but an efficient and stable expression vector is lacking. In the present study, a vector named pCCF containing chloramphenicol acetyltransferase (CAT) reporter gene cassettes was constructed. The cassettes were flanked by a β-interferon MAR at the 5′ upstream of the reporter gene cassettes,...
Ran-binding protein in microtubule organising centre (RanBPM) was originally isolated as a protein that binds to the small GTPase Ran. Recently our group and other groups reported that RanBPM was associated with several proteins and composed a large protein complex. Here, we used tandem MS with an antibody against RanBPM to purify this complex from a soluble extract of HEK293 cells: we identified...
A newly emerged periodontopathic pathogen Tannerella forsythia (formerly Bacteroides forsythus), a Gram-negative, filament-shaped, strict anaerobic, non-pigmented oral bacterium, possesses a surface (S-) layer. In our previous studies, the S-layer has been isolated, and shown to mediate hemagglutination, adhesion/invasion of epithelial cell, and murine subcutaneous abscess formation.In the present...
