(Submitter supplied) Point mutations in nuclear structural protein lamin A produce rare, tissue-specific diseases called laminopathies. The introduction of a human Emery Dreifuss Muscular Dystrophy (EDMD)-inducing mutation (lamin A-Y45C) into C. elegans lamin (LMN-Y59C), recapitulates many EDMD phenotypes, and correlates with hyper-sequestration of heterochromatic arrays at the nuclear periphery. Using muscle-specific emerin Dam-ID, we also document the misorganization of endogenous chromatin in the LMN-Y59C mutant. more...

(Submitter supplied) Development in multicellular organisms is governed by a carefully orchestrated program of gene expression controlled by both genetic and epigenetic factors1,2. Histone H3 lysine 9 methylation (H3K9me) is the defining modification of heterochromatin, which is thought to have two main functions. It silences satellite repeats and transposable elements to ensure genome stability3, and stabilizes differentiated states by repressing tissue-specific genes4,5. more...

(Submitter supplied) Laminopathies are caused by mutations in components of the nuclear envelope (NE). While most NE components are widely expressed, laminopathies affect only a subset of tissues. However, the understanding of the molecular mechanisms that explain this phenomenon is still elusive. Here we have performed RNA-Seq analysis in adult C. elegans nematodes comparing gene expression in wild type and single and double mutants of two components of the NE, EMR-1 and LEM-2. more...

(Submitter supplied) Packaging genomic regions into silenced heterochromatin is critical to maintain organismal viability and tissue identity. Methylation of histone H3 on lysine 9 (H3K9me) marks heterochromatin. Here we show that in addition to catalyzing H3K9me, the C. elegans histone methyltransferase MET-2 (SETDB1-like) has a second non-catalytic function that can itself contribute to gene repression. We find that subnuclear concentrates, or foci, of MET-2 correlate with efficient HMT activity, yet foci composed of catalytic-deficient MET-2 are also able to mediate transcriptional silencing. more...

(Submitter supplied) The segregation of the genome into accessible euchromatin and histone H3 lysine 9 methylated (H3K9me) heterochromatin is essential for the repression of repetitive elements and tissue-specific genes. In C. elegans, the SETDB1 homolog MET-2 catalyzes H3K9me1 and me2. In worms as in vertebrates, the regulation of this crucial enzyme remains enigmatic. Contrary to the localization of overexpressed MET-2, we find endogenous MET-2 to be nuclear throughout development, enriched in perinuclear foci in a cell cycle-dependent manner. more...

(Submitter supplied) Summary: Genetic disorders of muscle cause muscular dystrophy, and are some of the most common inborn errors of metabolism. Muscle also rapidly remodels in response to training and innervation. Muscle weakness and wasting is important in such conditions as aging, critical care medicine, space flight, and diabetes. Finally, muscle can also be used to investigate systemic defects, and the compensatory mechansisms invoked by cells to overcome biochemical and genetic abnormalities. more...

(Submitter supplied) Genomic regions preferentially associate with regions of similar transcriptional activity, partitioning genomes into active and inactive compartments within the nucleus. Here we explored mechanisms controlling genome compartment organization in C. elegans and investigated roles for compartments in regulating gene expression. The distal arms of C. elegans chromosomes, which are enriched for heterochromatic histone modifications including H3K9me, interact with each other both in cis and in trans, while interacting less frequently with central regions of chromosomes, leading to genome compartmentalization. more...
