Endometriosis is a common gynecological condition with unclear pathogenesis. Although a dysregulated lncRNA expression profile has been speculated, very few studies have addressed this hypothesis. We determined the differential lncRNA and mRNA expression patterns between endometriosis and control tissues, and between eutopic and normal endometrium in the proliferative phase, using RNA sequencing....
The rabbitfish Siganus canaliculatus was the first marine teleost demonstrated to have the ability of biosynthesizing long-chain polyunsaturated fatty acids (LC-PUFA) from C18 PUFA precursors, and all genes encoding the key enzymes for LC-PUFA biosynthesis have been cloned and functionally characterized, which provides us a potential model to study the regulatory mechanisms of LC-PUFA biosynthesis...
Adipogenin (ADIG) is an adipocyte-specific membrane protein highly expressed in adipose tissues and is increased during the adipocyte differentiation. However, the roles and mechanisms of ADIG on fat accumulation and adipocyte differentiation in ex vivo still largely unknown. In this study, we isolated bovine myosatellite cells based on adhesion characteristics to investigate whether ADIG overexpression...
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...
E3 ubiquitin ligases are a large gene family that plays a diversity of roles in spermatogenesis. In this study, the functional characterization of a neuralized E3 ubiquitin protein ligase 3 (neurl3) revealed its potential participation in spermatogenesis. Firstly, we found that neurl3 exhibited male-biased transcription and that its translation was predominant in testis germ cells. The knockdown of...
Mitochondrial genomes can provide basic information for phylogenetic analysis and evolutionary studies. We present here the mitochondrial genome of Cynoglossus gracilis, which is 16,565bp in length. Numerous distinct regions were identified, including 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, a light-strand replication origin, and a control region. Interestingly, we detected rearrangement...
Hip cartilage destruction is consistently observed in the non-traumatic osteonecrosis of femoral head (NOFH) and accelerates its bone necrosis. The molecular mechanism underlying the cartilage damage of NOFH remains elusive. In this study, we conducted a systematically comparative study of gene expression profiles between NOFH and osteoarthritis (OA). Hip articular cartilage specimens were collected...
FoxA transcription factors play vital roles in regulating the expression of organ-specific genes. BmSGF1, the sole FoxA family member in Bombyx mori, is required for development of the silk gland. However, the function of BmSGF1 in development of the nervous system in the silkworm remains unknown. Here, we show that the amino acids sequence of BmSGF1 is evolutionarily conserved in its middle region...
Real-time reverse transcription quantitative polymerase chain reaction (RT-qPCR) has become the most common technique to investigate mRNA expression levels of target genes. In order to obtain accurate results, stable reference genes need to be selected for normalization in an experimental study. Human retinal endothelial cells (HREC) cultured in a hypoxic and hyperglycemic environment is a potential...
We previously reported that regenerating islet-derived protein 3 alpha (REG3A) exacerbates pancreatic malignancies. The mechanism of this effect has not been clearly elucidated. Here we first identified key differentially expressed genes (DEGs) and signal pathways in the pancreatic cancer cell line SW1990, compared to two control cell lines, by microarray analysis. We then identified key genes and...
The development of the nervous system is based on the growth and connection of axons, and axon guidance molecules are the dominant regulators during this course. Robo, as the receptor of axon guidance molecule Slit, plays a key role as a conserved repellent cue for axon guidance during the development of the central nervous system. However, the function of Robo in the silkworm Bombyx mori is unknown...
Axon guidance is critical for proper wiring of the nervous system. During the neural development, the axon guidance molecules play a key role and direct axons to choose the correct way to reach the target. Robo, as the receptor of axon guidance molecule Slit, is evolutionarily conserved from planarians to humans. However, the function of Robo in the silkworm, Bombyx mori, remained unknown. In this...
In the present study, we characterized the transcriptional regulatory region (KF038144) controlling the expression of a constitutive FAD2 in Brassica napus. There are multiple FAD2 gene copies in B. napus genome. The FAD2 gene characterized and analyzed in the study is located on chromosome A5 and was designated as BnFAD2A5-1. BnFAD2A5-1 harbors an intron (1192bp) within its 5′-untranslated region...
Aquatic organisms such as cichlids, coelacanths, seals, and cetaceans are active in UV–blue color environments, but many of them mysteriously lost their abilities to detect these colors. The loss of these functions is a consequence of the pseudogenization of their short wavelength-sensitive (SWS1) opsin genes without gene duplication. We show that the SWS1 gene (Bden S1 ψ) of the deep-sea...
Toothed whales and bats have independently evolved specialized ultrasonic hearing for echolocation. Recent findings have suggested that several genes including Prestin, Tmc1, Pjvk and KCNQ4 appear to have undergone molecular adaptations associated with the evolution of this ultrasonic hearing in mammals. Here we studied the hearing gene Cldn14, which encodes the claudin-14 protein and is a member...
Pancreatic ribonuclease gene (RNASE1) was previously shown to have undergone duplication and adaptive evolution related to digestive efficiency in several mammalian groups that have evolved foregut fermentation, including ruminants and some primates. RNASE1 gene duplications thought to be linked to diet have also been recorded in some carnivores. Of all mammals, bats have evolved the most diverse...

The mechanistic target of rapamycin (mTOR) plays a key role in growth and development. In the present study, a cDNA encoding mTOR protein was identified from common carp Cyprinus carpio muscle. The open reading frame of this cDNA encodes 2515 deduced amino acid residues that showed high sequence similarity with its zebrafish Danio rerio counterparts. Bioinformatic analysis showed that the protein...
The mouse keratocan gene (Ktcn) expression tracks the corneal morphogenesis during eye development and becomes restricted to keratocytes of the adult, implicating a cornea-specific gene regulation of the mouse Ktcn [J. Biol. Chem., 273 (1998) 22584-22588]. To examine the functionality of the mouse Ktcn promoter, we have cloned and sequenced a 3.2kb genomic DNA fragment 5' of the mouse Ktcn gene, which...
