MetabolomicsF-actin dynamics couples sphingolipid metabolism to epithelial barrier integrity in chronic colitis
Intestinal barrier dysfunction is a hallmark of gastrointestinal disorders, including inflammatory bowel diseases (IBD). In IBD, the disruption of the gut barrier causes liquid loss and persistent immune response. Understanding the cellular events underlying epithelial barrier disruption during chro...

MetabolomicsTFAM loss induces nuclear actin assembly upon mDia2 malonylation to promote liver cancer metastasis
The mechanisms underlying cancer metastasis remain poorly understood. Here, we report that TFAM deficiency rapidly and stably induced spontaneous lung metastasis in mice with liver cancer. Interestingly, unexpected polymerization of nuclear actin was observed in TFAM-knockdown HCC cells when cytoske...

TranscriptomicsActin Cytoskeleton Integrates Auxin and Brassinosteroid Signaling in Plants.
We describe a new mutant allele of the ACTIN2 gene with enhanced actin dynamics, displaying a broad array of twisting and bending phenotypes that resemble BR-treated plants. Moreover, auxin transcriptional regulation is enhanced on the mutant background, supporting the idea that shaping actin filame...

ProteomicsKLF2-induced actin shear fibers control both alignment to flow and JNK signaling in vascular endothelium
The shear stress-induced transcription factor Krüppel-like factor 2 (KLF2) confers anti-inflammatory properties to endothelial cells through inhibition of activator protein 1, presumably by interfering with MAPK cascades. To gain insight into the regulation of these cascades by KLF2, we used antibo...

TranscriptomicsTranscription profiling of human dendritic cells from PLOSL patients show abnormalities in pathways of actin bundling and immune response
This study was aimed to identify pathways associated with loss-of-function of the DAP12/TREM2 receptor complex and thus gain insight into pathogenesis of PLOSL (polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy). Transcript profiles of PLOSL patients' DCs showed differenti...

ProteomicsLysine acetylation of F-actin decreases tropomyosin-based inhibition of actomyosin activity
Actin was acetylated on lysine residues with acetic anhydride to determine its impaction on the contractile properties of the thin filaments including, actin's ability to undergo crossbridge cycling with myosin, actin's affinity for tropomyosin, and the impact of actin acetylation on calcium regulat...

ProteomicsNebulette reinforces podocyte structural integrity by linking actin and vimentin filaments
One of the key aspects of the specialized podocyte morphology is the segregation and organization of distinct cytoskeletal filaments into different subcellular components, for which the exact mechanisms remain poorly understood. By screening the time-dependent proteomic changes within the rat puromy...

TranscriptomicsComparative transcriptome analysis of DFAT cells after the treatment with Y-27632 and the transfection of Mkl1 siRNA
Cellular differentiation is regulated through activation and repression of defined transcription factors. A hallmark of differentiation is a pronounced change in cell shape, which is determined by dynamics of the actin cytoskeleton. In de-differentiated fat (DFAT) cells and 3T3-L1 cells, we showed t...

TranscriptomicsGPM6B regulates osteoblast differentiation and induction of mineralization by controlling cytoskeleton and matrix vesicle release.
Analysis of GPM6B silenced osteogenic hMSC at gene expression level. Analysis is showing significant changes in genes involved in cytoskeleton organization and biogenesis. Immunocytochemistry confirms changed distribution of actin filaments and change in shape and in size of focal adhesions upon GP...

TranscriptomicsA putative network of actin-associated cytoskeletal proteins in glomerular podocytes defined by co-purified mRNAs
Identification of a putative network of actin-associated cytoskeletal proteins in glomerular podocytes defined by co-purified mRNAs. An experimental purification in which a presumed RNA binding protein was used for an RNA immunoprecipitation and microarray analysis (RIP-CHIP). Total cell extracts w...
