miR-101-1 expression pattern in Qinchuan cattle and its role in the regulation of cell differentiation.
In this study, we designed to examine the biological function of bovine-miR-101-1. The bovine miR-101-1 was detected in the skeletal muscle of fetal, calf and adult cattle. Its abundance was significantly higher in the skeletal muscle of calf cattle than that in fetal and adult cattle. In the course of C2C12 myoblast differentiation, the expression of miR-101-1 gradually increased. Transfected the exogenous miR-101-1 into the C2C12 myoblast could decrease myotube formation, and the mRNA expression levels of the myogenic marker genes MyOD, MyOG and MyHC were up-regulated. The protein level of MyOD, MyOG and MyHC were also u...

Multiplex PCR and NGS-based identification of mRNA splicing variants: Analysis of BRCA1 splicing pattern as a model.
Abstract Alternative pre-mRNA splicing increases transcriptome plasticity by forming naturally-occurring alternative splicing variants (ASVs). Alterations of splicing processes, caused by DNA mutations, result in aberrant splicing and the formation of aberrant mRNA isoforms. Analyses of hereditary cancer predisposition genes reveal many DNA variants with unknown clinical significance (VUS) that potentially affect pre-mRNA splicing. Therefore, a comprehensive description of ASVs is an essential prerequisite for the interpretation of germline VUS in high-risk individuals. To identify ASVs in a gene of interest, we h...

HMG-box factor SoxD/Sox15 and homeodomain-containing factor Xanf1/Hesx1 directly interact and regulate the expression of Xanf1/Hesx1 during early forebrain development in Xenopus laevis.
Abstract The homeodomain-containing transcription factor Anf (also known as Rpx/Hesx1 in mammals) plays an important role during the forebrain development in vertebrates. Here we demonstrate the ability of the Xenopus laevis Anf, Xanf1/Hesx1, to directly bind SRY-related HMG-box-containing transcription factor SoxD/Sox15 and to cooperate with the latter during regulating of the expression of Xanf1/Hesx1 own gene. As we have shown by GST pull-down, EMSA and the luciferase reporter assays, Xanf1/Hesx1 and SoxD/Sox15 bind the Xanf1/Hesx1 promoter region counteracting the inhibitory effect of Xanf1/Hesx1 alone. This f...

Cooperative regulation of Gja1 expression by members of the AP-1 family cJun and cFos in TM3 Leydig and TM4 Sertoli cells.
Abstract Within the testis, connexin43 encoded by Gja1 plays an important role in cell-to-cell communication between Leydig cells as well as between Sertoli cells and spermatogonia. In the adult male, Leydig cells are the principal producers of testosterone sustaining spermatogenesis, while Sertoli cells nourish, protect and support the differentiating germ cells. It has been shown previously that members of the AP-1 family regulate Gja1 expression in myometrial cells, suggesting that such regulatory mechanism may also be relevant within the testis. Thus, we performed cotransfections of AP-1 expression plasmids wi...

Single cell transcriptome analysis of muscle satellite cells reveals widespread transcriptional heterogeneity.
Abstract Tissue specific stem cells are indispensable contributors to adult tissue maintenance, repair, and regeneration. In skeletal muscle, satellite cells (SCs) are the resident muscle stem cell population and are required to maintain skeletal muscle homeostasis throughout life. Increasing evidence suggests that SCs are a heterogeneous cell population with substantial biochemical and functional diversity. A major limitation in the field is an incomplete understanding of the nature and extent of this cellular heterogeneity. Single cell analyses are well suited to addressing this issue, especially when coupled to...

MicroRNA-219-5p inhibits the proliferation, migration, and invasion of epithelial ovarian cancer cells by targeting the Twist/Wnt/ β-catenin signaling pathway.
In this study, we sought to explore the potential functions of miR-219-5p in epithelial ovarian cancer. Herein, we found that miR-219-5p levels were significantly decreased in epithelial ovarian cancer tissues and cell lines. Further experiments showed that overexpression of miR-219-5p inhibited epithelial ovarian cancer cell proliferation, migration, and invasion, and suppressed the Wnt/β-catenin signaling pathway. By contrast, suppression of miR-219-5p exhibited the opposite effects. Twist was identified as a downstream target of miR-219-5p, and its expression was directly regulated by miR-219-5p.

Silencing of the pentose phosphate pathway genes influences DNA replication in human fibroblasts.
Abstract Previous reports and our recently published data indicated that some enzymes of glycolysis and the tricarboxylic acid cycle can affect the genome replication process by changing either the efficiency or timing of DNA synthesis in human normal cells. Both these pathways are connected with the pentose phosphate pathway (PPP pathway). The PPP pathway supports cell growth by generating energy and precursors for nucleotides and amino acids. Therefore, we asked if silencing of genes coding for enzymes involved in the pentose phosphate pathway may also affect the control of DNA replication in human fibroblasts. ...

Counter regulation of ECRG4 gene expression by hypermethylation-dependent inhibition and the Sp1 transcription factor-dependent stimulation of the c2orf40 promoter.
Abstract The human cytokine precursor ECRG4 has been associated with multiple physiological, developmental and pathophysiological processes involving cell proliferation, cell migration, innate immunity, inflammation, cancer progression and metastases. Although down-regulation of ECRG4 gene expression has been largely attributed to hypermethylation of CpG islands in the 5'untranslated region of the ECRG4 promoter, the mechanisms that underlie the dynamics of its regulation have never been systematically described. Here we show that the ECRG4 gene is widely expressed in human tissues and report that its core promote...

Whole-exome sequencing identified a homozygous mutation in the CEP135 gene (c.A1364T:p.D455V), with CEP135 previously reported to play a role in centriole biogenesis and specifically central pair assembly. D455V-mutated proteins formed protein aggregates in the centrosome and the flagella, which might potentially affect th...

Comparative profiling of microRNAs and their association with sexual dimorphism in the fig wasp Ceratosolen solmsi.
In this study, we constructed six small RNA libraries from female and male wasps in three different developmental stages, i.e., larvae, early pupae, and late pupae. We detected known miRNAs and predicted novel miRNAs, and compared their expression patterns in both sexes and among different developmental stages. We focused mainly on the miRNAs with significantly different expression patterns between sexes and among different life stages, as well as their putative associations with metamorphosis and the formation of sexual dimorphism.

Identification, structural characterization and expression analysis of a novel carbonic anhydrase from freshwater mussel Hyriopsis cumingii.
In this study, an α-carbonic anhydrase (α-CA), HcCA3, from Hyriopsis cumingii was characterized. The full-length cDNA of HcCA3 was 1628bp, including a CA domain and an ORF of 1053bp which encoded 350 amino acids. Its predicted molecular weight was 39.69kDa and the pI was 5.92. qRT-PCR was used to determine the expression of the gene in various tissues at 0h, 3h, 6h, 12h, 24h, 48h, 96h, 7d, 14d, 21d, 28d and 35d after inserting the pearl nucleus. The results showed that the HcCA3 was highly expressed in the mantle, whereas its expression was low in other tissues. Expression in the posterior mantle pallial (pMP) ...

Identification of apoptosis-related genes Bcl2 and Bax from yellow catfish Pelteobagrus fulvidraco and their transcriptional responses to waterborne and dietborne zinc exposure.
Abstract Apoptosis plays a key role in the physiology of multicellular organisms, and has been well studied in mammals, but not in teleosts. Zinc (Zn) has been shown to be an important regulator of apoptosis and apoptosis involves in the regulation of lipid metabolism. Moreover, our recent study indicated that waterborne and dietborne Zn exposure differently influenced lipid metabolism in Pelteobagrus fulvidraco, but further mechanism remained unknown. The hypothesis of the present study is that apoptosis mediated the Zn-induced changes of lipid metabolism of P. fulvidraco subjected to different exposure pathways....

Leptin siRNA promotes ovarian granulosa cell apoptosis and affects steroidogenesis by increasing NPY2 receptor expression.
In conclusion, knockdown of leptin significantly affected ovarian steroidogenesis and ovarian function through NPY. siLeptin transfection impaired the activation of JAK2/STAT3 and contributed to ovarian granulosa cell apoptosis partially through up-regulating NPY2R expression.

RasGRP3 controls cell proliferation and migration in papillary thyroid cancer by regulating the Akt-MDM2 pathway.
In this study, we demonstrate that RasGRP3 was overexpressed in PTC tissues and cell lines. Downregulation of RasGRP3 using small interfering (si) RNA significantly inhibited PTC cell proliferation and migration in vitro, and tumor growth in vivo, reflecting an oncogenic role of RasGRP3 in PTC. We subsequently identified that the expression of mouse double minute 2 homolog (MDM2) and phosphorylated Akt (p-Akt) was significantly decreased in RasGRP3-downregulated PTC cells. Overexpression of MDM2 attenuated the function of si-RasGRP3. Taken together, our data show that RasGRP3 exerts its oncogenic effect in PTC through Akt-...

Genotype-dependent regulation of drought-responsive genes in tolerant and sensitive sugarcane cultivars.
Abstract Drought is the most damaging among the major abiotic stresses. Transcriptomic studies allow a global overview of expressed genes, providing the basis for molecular markers development. Here, the HT-SuperSAGE technique allowed the evaluation of four drought-tolerant cultivars and four-sensitive cultivars, after 24h of irrigation suppression. We identified 9831 induced unitags from roots of the tolerant cultivars with different regulations by the -sensitive cultivars after the applied stress. These unitags allowed a proposal of 15 genes, whose expressed profiles were validated by RT-qPCR, evaluating each cu...
