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...

Wnt signaling is an important pathway that regulates several aspects of embryogenesis, stem cell maintenance, and neural connectivity. We have recently determined that opioids decrease Wnt secretion, presumably by inhibiting the recycling of the Wnt trafficking protein Wntless (Wls). This effect appears to be mediated by protein-protein interaction between Wls and the mu-opioid receptor (MOR), the primary cellular target of opioid drugs. The goal of this study was to identify novel protein interactors of Wls that are expressed in the brain and may also play a role in reward or addiction...

Severe influenza diseases with high mortality have been frequently reported, especially in those patients infected with avian influenza A (H5N1, H7N9 or H10N8) or during a pandemic. Respiratory distress, which is attributed to alveolar damage associated with immunopathological lesions, is the most common cause of death. There is a wealth of information on pathogenesis or treatment options. In this study, we showed that high levels of C-reactive protein (CRP) were induced and correlated with complement activation in patients infected with severe influenza A (H5N1, H7N9 or H10N8), and higher levels were induced in fatal patients than in survivors...

The genetic architecture of dementia with Lewy bodies (DLB) is increasingly taking shape. Initially, genetic research focused mainly on linkage and candidate gene studies in small series of DLB patients. More recently, association and exome sequencing studies in larger groups have been conducted, and have shown that several variants in GBA and the APOE ε4 allele are important genetic risk factors for DLB. However, genetic research in DLB is still in its infancy. So far, many genetic studies have been biased and performed in clinically and pathologically heterogeneous populations...

The variation of I27L gene closely relates to increasing risk of type 2 diabetes, thus it is greatly significant to develop various methods for its identification or monitoring. We report here a novel label-free electrochemiluminescent (ECL) biosensor for simple and effective determination of I27L gene based on Au nanoparticles functionalized ITO electrode. The ECL technique is employed to monitor the hybridization of DNA strands by measuring the changes of its intensity. Here, the ECL signal was quenched by blocked access of probe (luminol anion) owing to the electrostatic repulsion of negatively charged sensor surface and the space resistance...

Improving resistance durability involves to be able to predict the adaptation speed of pathogen populations. Identifying the genetic bases of pathogen adaptation to plant resistances is a useful step to better understand and anticipate this phenomenon. Globodera pallida is a major pest of potato crop for which a resistance QTL, GpaVvrn , has been identified in Solanum vernei. However, its durability is threatened as G. pallida populations are able to adapt to the resistance in few generations. The aim of the present study was to investigate the genomic regions involved in the resistance breakdown by coupling experimental evolution and high-density genome scan...

High-risk Human papillomaviruses (HPVs) cause cervical cancer, and while there are good prophylactic vaccines on the market, these are ineffective against established infections, creating a clear need for therapeutic vaccines. The HPV E7 protein is one of the essential oncoproteins for the onset and maintenance of malignancy, and is therefore an ideal therapeutic vaccine target. We fused the HPV-16 E7 protein to the Limulus polyphemus anti-lipopolysaccharide factor (LALF32-51 ), a small hydrophobic peptide that can penetrate cell membranes and that has immunomodulatory properties...

Members of the mammalian Vestigial-like (VGLL) family of transcriptional cofactors activate genes in response to a wide variety of environmental cues. Recently, VGLL proteins have been proposed to regulate key signaling networks involved in cancer development and progression. However, the biological and clinical significance of VGLL dysregulation in human breast cancer pathogenesis remains unknown. Here, we report that diminished VGLL4 expression, but not VGLL1-3, correlated with both shorter relapse-free survival and shorter disease-specific survival of cancer patients with different molecular subtypes of breast cancer...

In addition to high intelligence, humans evolved specialized social-cognitive skills, which are specifically affected in children with autism spectrum disorder (ASD). Genes affected in ASD represent suitable candidates to study the evolution of human social cognition. We performed an evolutionary analysis on 68 genes associated to neurodevelopmental disorders; our data indicate that genetic diversity was shaped by distinct selective forces, including natural selection and introgression from archaic hominins...

Present-day terrestrial analogue sites are crucial ground truth proxies for studying life in geochemical conditions close to those assumed to be present on early Earth or inferred to exist on other celestial bodies (e.g. Mars, Europa). Although hypersaline sapropels are border-of-life habitats with moderate occurrence, their microbiological and physicochemical characterization lags behind. Here, we study the diversity of life under low water activity by describing the prokaryotic communities from two disparate hypersaline sapropels (Transylvanian Basin, Romania) in relation to geochemical milieu and pore water chemistry, while inferring their role in carbon cycling by matching taxa to known taxon-specific biogeochemical functions...

Nocardioides sp. strain PD653 was the first aerobic bacterium capable of mineralizing hexachlorobenzene (HCB) that was identified. In this study, strain PD653-B2, which was unexpectedly isolated from a subculture of strain PD653, was found to lack the ability to transform HCB or pentachloronitrobenzene into pentachlorophenol. Comparative genome analysis of the two strains revealed that genetic rearrangement had occurred in strain PD653-B2, with a genomic region present in strain PD653 being deleted. In silico analysis allowed three open reading frames within this region to be identified as candidate genes involved in HCB dechlorination...

Parasitic organisms have to cope with the defences deployed by their hosts and this can be achieved adopting immune evasion strategies or optimal life history traits according to the prevailing pattern of immune-mediated mortality. Parasites often encounter variable immune environments both within and between hosts, promoting the evolution of plastic strategies instead of fixed responses. Here, we explored the plasticity and micro-evolutionary responses of immunomodulatory mechanisms and life history traits to the immune environment provided by the host, using the parasitic nematode Heligmosomoides polygyrus...

Emerging reports suggest microRNAs (miRNAs) play a vital role in the progression of malignant tumors. MiR-30a is downregulated in a variety of cancers and acts as a tumor suppressing gene. However, the molecular mechanisms of miRNA-30a in hepatocellular carcinoma (HCC) are still unclear. Hereby, in this study, we detected that miR-30a expression was significantly down-regulated in both HCC tissues compared with adjacent non-cancerous liver tissues, and we also observed that miR-30a expression was lower in HCC cell lines than that of normal controls...
