Metallothionein (MT) is the main protein involved in the homeostasis of metallic micronutrients and in cellular defence against heavy metals and reactive oxygen species. Found in almost all vertebrate tissues, MT presence and localization in the testis has been controversial. In the present study, by using in situ hybridization and immunohistochemical analysis we assessed the localization of both MT transcript and protein in Podarcis sicula testes during two different phases of the reproductive cycle: the autumnal resumption and the spring-early summer mating period...

Kun Wang, Xin Wang, Ming Li, Tao Shi, Pingfang Yang
In this study, we sequenced and analyzed the expression and evolution of rice miRNA genes participating pollen-pistil interaction that is crucial to rice yield. Pollen-pistil interaction is an essential reproductive process for all flowering plants. While microRNAs (miRNAs) are important noncoding small RNAs that regulate mRNA levels in eukaryotic cells, there is little knowledge about which miRNAs involved in the early stages of pollen-pistil interaction in rice and how they evolve under this conserved process...

Si-In Yu, Byeong-Ha Lee
In order to understand plant stress tolerance and its application, it is important to identify the signaling components involved in the stress-regulated gene expression. One initial step for this is generation of a stress-inducible luminescent Arabidopsis and its use in genetic mutant screening. Here, we describe how to generate a transgenic Arabidopsis line harboring a single copy of the STABILIZED1 (STA1) promoter-driven luciferase transgene (STA1p-LUC) as an example. STA1 is a pre-mRNA splicing factor Prp6p homolog and is induced by cold and heat stresses...

There have been great research advances in epigenetics, RNA splicing, and mRNA processing over recent years. In parallel, there have been many advances in abiotic stress and Abscisic Acid (ABA) signaling. Here we overview studies that have examined stress-induced changes in the epigenome and RNA processing as well as cases where disrupting these processes changes the plant response to abiotic stress. We also highlight some examples where specific connections of stress or ABA signaling to epigenetics or RNA processing have been found...

Long noncoding RNAs (lncRNAs) are important regulators for a variety of biological processes. Chondrogenic differentiation of mesenchymal stem cells (MSCs) is a crucial stage in chondrogenesis while chondrocyte hypertrophy is related to endochondral ossification and osteoarthritis. However, the effects of lncRNAs on chondrogenic and hypertrophic differentiation of mouse MSCs are unclear. To explore the potential mechanisms of lncRNAs during chondrogenesis and chondrocyte hypertrophy, microarray was performed to investigate the expression profiles of lncRNA and mRNA in MSCs, pre-chondrocytes, and hypertrophic chondrocytes...

DNA methylation is an important regulator on the mRNA expression. However, a genome-wide correlation pattern between DNA methylation and mRNA expression in human peripheral blood mononuclear cells (PBMCs) is largely unknown. The comprehensive relationship between mRNA and DNA methylation was explored by using four types of correlation analyses and a genome-wide methylation-mRNA expression quantitative trait locus (eQTL) analysis in PBMCs in 46 unrelated female subjects. An enrichment analysis was performed to detect biological function for the detected genes...

BACKGROUND: Triple-negative breast cancers (TNBCs) are defined by their lack of oestrogen receptor, progesterone receptor and epidermal growth factor receptor 2. Although heterogeneous, the majority are aggressive and treatment options are limited. Caveolin acts as tumour suppressor or promoter depending on the cancer type. AIM: In this study, we aimed to determine if the expression levels of the candidate biomarker caveolin-1 on stromal or tumour cells were associated with clinicopathological parameters and disease outcomes in TNBCs from an ethnically diverse cohort of Asian women...

BACKGROUND: Dairy working increases the prevalence of lower airway respiratory diseases, especially COPD and asthma. Epidemiological studies have reported that chronic inhalation of organic dusts released during specific daily tasks could represent a major risk factor for development of these pathologies in dairy workers. Knowledge on size, nature and biological activity of such organic dusts remain however limited. OBJECTIVE: To compare size distribution, microbial composition and cellular effects of dusts liberated by the spreading of straw bedding in five French dairy farms located in Brittany...

The ATP-binding cassette transporter ABCC4 (multidrug resistance protein 4, MRP4) mRNA level is a strong predictor of poor clinical outcome in neuroblastoma which may relate to its export of endogenous signalling molecules and chemotherapeutic agents. We sought to determine whether ABCC4 contributes to development, growth and drug response in neuroblastoma in vivo. In neuroblastoma patients, high ABCC4 protein levels were associated with reduced overall survival. Inducible knockdown of ABCC4 strongly inhibited the growth of human neuroblastoma cells in vitro and impaired the growth of neuroblastoma xenografts...

Converging evidence indicates that abnormal glutamatergic and synaptic systems may be associated with the pathophysiology of depression. Over-activation of corticotropin-releasing hormone (CRH) neurons in the hypothalamic paraventricular nucleus (PVN) plays a key role in the hypothalamic-pituitary-adrenal (HPA) axis hyperactivity and is a prominent feature in depression. In this study, we examined the effect of chronic unpredictable stress (CUS) in rats on the expression of AMPA subunit GluR1 protein in the hypothalamic PVN as well as on the expression of GluR1 and several synapse-related proteins in the hypothalamus...

Di-n-butyl phthalate (DBP) and its active metabolite, monobutyl phthalate (MBP) are the most common endocrine disrupting chemicals. Many studies indicated the effects of MBP on male steroidogenesis, however, little attention have been paid on the effects of low levels of MBP on female steroidogenesis. This study was aimed to assess steroidogenesis stimulated by low-dose MBP on primary cultured ovarian granulosa cells (mGCs). Ovarian granulosa cells were isolated from ICR female mice. Hormone levels in medium were detected by ELISA, mRNA and protein expressions of vimentin, NF-κB p65 and phosphorylation of NF-κB p65 (p-p65) were assayed by qRT-PCR, western blot and immunohistochemistry, respectively...

The Chinese mitten crab Eriocheir sinensis is an important economic crustacean that has been exposed to various diseases. Spiroplasma eriocheiris, isolated from tremor-diseased E. sinensis, was first identified as a lethal pathogen of freshwater crustaceans. To understand the pathogenesis of S. eriocheiris to E. sinensis, the transcriptomic profiles of haemocytes in the experimental and control groups at 1 d and 7 d post-injection were obtained using Illumina HiSeq 2500. These results showed that 40,358,724, 44,462,112, 45,516,576 and 37,713,728 paired-end clean reads were obtained from the cDNA libraries of DZ1 (the control group at 1 d), DZ7 (the control group at 7 d), SY1 (the experimental group at 1 d) and SY7 (the experimental group at 7 d), respectively...

Microphthalmia-associated transcription factor (MITF) regulates the transcription of its target genes by binding to their promoters. In this study, an MITF gene, MpMITF was identified in the clam Meretrix petechialis. The full-length cDNA of MpMITF is 3564 bp with an ORF of 1365 bp. The deduced amino acid sequence consists of a conserved functional structure of bHLH-LZ, which could bind with E-box. The mRNA and protein expression levels of MpMITF were significantly up-regulated 6 h post-Vibrio injection. The mRNA expression of MpMITF increased on day 2 and peaked on day 10 post-Vibrio immersion...

A decade ago, we believed that at least 300 RNA binding proteins (RBPs) were encoded in our genomes based on annotations of known or predicted RNA binding domains. Deciphering the roles of those RBPs in regulated gene expression was a vast frontier awaiting exploration. Since then, the field has developed a number of key tools that navigate the landscape of cellular RNA. These rely principally on UV crosslinking to create covalent bonds between RBPs and target RNAs in vivo, revealing not only target identities but also local binding sites upon RNA-Seq...

While the conventional two-dimensional (2D) culture protocol is well accepted for the culture of mesenchymal stem cells (MSCs), this method fails to recapitulate the in vivo native three-dimensional (3D) cellular microenvironment, and may result in phenotypic changes, and homing and migration capacity impairments. MSC preparation in 3D culture systems has been considered an attractive preparatory and delivery method recently. We seeded human umbilical cord-derived MSCs (hUCMSCs) in a 3D culture system with porcine acellular dermal matrix (PADM), and investigated the phenotypic changes, the expression changes of some important receptors, including Toll-like receptors (TLRs) and C-X-C chemokine receptor type 4 (CXCR4) when hUCMSCs were transferred from 2D to 3D systems, as well as the alterations in in vivo homing and migration potential...

Male premature neonates are more susceptible than females to the development of bronchopulmonary dysplasia (BPD). The reasons underlying sexually dimorphic outcomes in premature neonates are not known. GDF15 (Growth and differentiation factor 15) is a secreted cytokine and plays a role in cell proliferation, apoptosis, and angiogenesis. In this study, we sought to elucidate the sex-specific expression of Gdf15 in the lung in vivo in neonatal hyperoxic lung injury and its regulation by Hif-1α, and to delineate the differences in GDF15 expression in male and female human umbilical venous endothelial cells in an in vitro model of oxygen toxicity...

Strong underwater acoustic noise has been known that may cause hearing loss and actual stress in teleost. However, the long-term physiological effects of relatively quiet but continuously noise on fish were less understood. In present study, milkfish, Chanos chanos, were exposed to the simulated-wind farm noise either quiet (109 dB re 1 μPa / 125.4 Hz; approx. 10-100m distant from the wind farm) or noisy (138 dB re 1 μPa / 125.4 Hz; nearby the wind farm) conditions for 24 hr, 3 days and 1 week. Comparing to the control group (80 dB re 1 μPa / 125...
