The Presence or Absence of Intestinal Microbiota Affects Lipid Deposition and Related Genes Expression in Zebrafish (Danio rerio)

2018

Understanding how intestinal microbiota alters energy homeostasis and lipid metabolism is a critical process in energy balance and health. However, the exact role of intestinal microbiota in the regulation of lipid metabolism in fish remains unclear. Here, we used two zebrafish models (germ-free and antibiotics-treated zebrafish) to identify the role of intestinal microbiota in lipid metabolism. Conventional and germ-free zebrafish larvae were fed with egg yolk. Transmission electron microscopy was used to detect the presence of lipid droplets in the intestinal epithelium. The results showed that, microbiota increased lipid accumulation in the intestinal epithelium. The mRNA sequencing tech…

A constitutive BCL2 down-regulation aggravates the phenotype of PKD1-mutant-induced polycystic kidney disease

2017

IF 5.340; International audience; The main identified function of BCL2 protein is to prevent cell death by apoptosis. Mice knock-out for Bcl2 demonstrate growth retardation, severe polycystic kidney disease (PKD), gray hair and lymphopenia, and die prematurely after birth. Here, we report a 40-year-old male referred to for abdominal and thoracic aortic dissection with associated aortic root aneurysm, PKD, lymphocytopenia with a history of T cell lymphoblastic lymphoma, white hair since the age of 20, and learning difficulties. PKD, which was also detected in the father and sister, was related to an inherited PKD1 mutation. The combination of PKD with gray hair and lymphocytopenia was also r…

Developmental transcriptomics in Atlantic haddock: Illuminating pattern formation and organogenesis in non-model vertebrates.

2016

Gadiforms such as Atlantic haddock comprise some of the world's most economically important fisheries. Understanding the early life history of these fish is a prerequisite for predicting effects of a changing environment and increased human activities. Robust assessment of the effects of environmental impacts on the embryos of non-model vertebrates is hampered by a lack of molecular resources and detailed knowledge regarding the regulation of genes and pathways in early development. Here we used mRNA sequencing to link transcriptional changes to developmental processes in haddock, specifically, pattern formation and organogenesis. Temporal expression of key developmental genes was tightly a…

Curcumin downregulates expression of opioid-related nociceptin receptor gene (OPRL1) in isolated neuroglia cells.

2018

Abstract Background: Curcumin (CC) exerts polyvalent pharmacological actions and multi-target effects, including pain relief and anti-nociceptive activity. In combination with Boswellia serrata extract (BS), curcumin shows greater efficacy in knee osteoarthritis management, presumably due to synergistic interaction of the ingredients. Aim: To elucidate the molecular mechanisms underlying the analgesic activity of curcumin and its synergistic interaction with BS. Methods: We performed gene expression profiling by transcriptome-wide mRNA sequencing in human T98G neuroglia cells treated with CC (Curamed), BS, and the combination of CC and BS (CC-BS; Curamin), followed by interactive pathways a…

Temperature-responsive miRNAs in Drosophila orchestrate adaptation to different ambient temperatures

2017

The majority of Drosophila genes are expressed in a temperature-dependent manner, but the way in which small RNAs may contribute to this effect is completely unknown as we currently lack an idea of how small RNA transcriptomes change as a function of temperature. Applying high-throughput sequencing techniques complemented by quantitative real-time PCR experiments, we demonstrate that altered ambient temperature induces drastic but reversible changes in sequence composition and total abundance of both miRNA and piRNA populations. Further, mRNA sequencing reveals that the expression of miRNAs and their predicted target transcripts correlates inversely, suggesting that temperature-responsive m…

C3cotyledons are followed by C4leaves: intra-individual transcriptome analysis ofSalsola soda(Chenopodiaceae)

2016

The genome of Salsola soda allows a transition from C3 to C4 photosynthesis. A developmental transcriptome series revealed novel genes showing expression patterns similar to those encoding C4 proteins.

Targeted mRNA sequencing of small formalin-fixed and paraffin-embedded breast cancer samples for the quantification of immune and cancer-related genes

2017

In the literature: February 2019

Malignant pleural mesothelioma (MPM) is a rare and lethal cancer associated to asbestos exposure. Currently, the pemetrexed and cisplatin combination chemotherapy remains the only approved treatment. In the last 5 years, a growing knowledge on mesothelioma pathobiology has translated into the development of multiple novel therapeutic strategies.1 One of the largest reports of comprehensive genomic profiling of MPM was conducted by Bueno and colleagues. Using RNA-seq data, they identified four distinct molecular subtypes, and through exome analysis, they found that BAP1 , NF2 , TP53 , SETD2 , DDX3X , ULK2 , RYR2 , CFAP45 , SETDB1 and DDX51 were significantly mutated.2 In an article recently …
