MetabolomicsJejunal inflammatory cytokines, barrier proteins and microbiome-metabolome responses to early supplementary feeding of Bamei suckling piglets

BACKGROUND: Dietary intervention has been reported to improve intestinal health. The intestinal microbiota of newborn animals plays a fundamental role in the development of intestinal function and the innate immune system. However, little is currently known about dietary interven...

MetabolomicsSarcopenic metabolomic profile reflected a sarcopenic phenotype associated with amino acid and essential fatty acid changes

INTRODUCTION: Although sarcopenia greatly affects health and quality of life in older people, its pathophysiological causes are not fully elucidated. To face this challenge, omics technologies can be used. The metabolome gives a vision of the interaction between the genome and t...

TranscriptomicsMouse MOV10L1 associates with Piwi proteins and is an essential component of the piRNA pathway
Piwi-interacting RNAs (piRNAs) are essential for silencing of transposable elements in the germline but their biogenesis is poorly understood. Here we demonstrate that MOV10L1, a germ cell-specific putative RNA helicase, is associated with Piwi proteins. Genetic disruption of the MOV10L1 RNA helicas...

ProteomicsExpanding the substantial interactome of NEMO using protein microarrays
Signal transduction by the NF-kappaB pathway is a key regulator of a host of cellular responses to extracellular and intracellular messages. The NEMO adaptor protein lies at the top of this pathway and serves as a molecular conduit, connecting signals transmitted from upstream sensors to the downstr...

TranscriptomicsNovel piRNA Pathway Components Identified Among the Class of TUDOR Domain Containing Proteins
PIWI proteins and their bound piRNAs form the core of a gonad specific small RNA silencing pathway in animals that protects the genome against the deleterious activity of transposable elements. Recent studies linked the piRNA pathway to TUDOR biology, where TUDOR domains of various proteins recogniz...

TranscriptomicsVreteno, a gonad-specific protein, is essential for germline development and primary piRNA biogenesis in Drosophila.
Here, we analyzed small RNA libraries derived from ovarian tissues heterozygous or mutant for the Tudor gene, Vreteno. In the absence of vret, Piwi-bound piRNAs are lost without changes in piRNA precursor transcript production, supporting a role for Vret in primary piRNA biogenesis. In the germline,...

TranscriptomicsA growth-essential Tetrahymena Piwi protein carries tRNA fragment cargo
Argonaute/Piwi proteins associate with small RNAs that typically provide sequence specificity for RNP function in gene and genome regulation. Here we show that Twi12, a Tetrahymena Piwi protein essential for growth, is loaded with mature tRNA fragments. The tightly bound ~18-22 nt tRNA 3M-bM-^@M-^Y ...

TranscriptomicsEssential functions for ID proteins at multiple checkpoints in natural killer T cell development
Thymic iNKT cell development is divided into four stages (stage 0-3) that are characterised, in C57BL/6 mouse strain, by the differential expression of surface markers, such as CD24, CD44 and NK1.1. During transition from immature to mature iNKT cell subsets, gene expression is tightly regulated. He...

TranscriptomicsCwc23, an essential J-protein critical for pre-mRNA splicing with a dispensable J-domain
J-proteins are structurally diverse, obligatory co-chaperones of Hsp70s, each with a highly conserved J-domain that plays a critical role in stimulation of Hsp70’s ATPase activity. The essential protein, Cwc23, is one of 13 J-proteins found in the cytosol and/or nucleus of Saccharomyces cerevisiae...
