Abstract:
Extracellular vesicles (EVs) are considered as transporters of biomarkers for the diagnosis of cardiac diseases, playing an important role in cell-to-cell communication during physiological and pathological processes. However, specific markers for the isolation and analysis of cardiac EVs are missing, imposing limitation on understanding their function in heart tissue. For this, we performed multiple proteomic approaches to compare EVs isolated from neonate rat cardiomyocytes and cardiac fibroblasts by ultracentrifugation, as well as EVs isolated from minced cardiac tissue and plasma by EVtrap

Abstract:
The Lim domain binding proteins (LDB1 and LDB2 in human and Chip in Drosophila) play critical roles in cell fate decisions through partnership with multiple Lim-homeobox and Lim-only proteins in diverse developmental systems including cardiogenesis, neurogenesis, and hematopoiesis. In mammalian erythroid cells, LDB1 dimerization supports long-range connections between enhancers and genes involved in erythropoiesis, including the β-globin genes. Single-stranded DNA binding proteins (SSBPs) interact specifically with the LDB/Chip conserved domain (LCCD) of LDB proteins and stabilize LDBs by prev

Abstract:
Inclusion body myositis (IBM) is a slowly progressive disorder belonging to the idiopathic inflammatory myopathies, and it represents the most common adult-onset acquired myopathy. The main clinical features include proximal or distal muscular asymmetric weakness, with major involvement of long finger flexors and knee extensors. The main histological findings are the presence of fiber infiltrations, rimmed vacuoles, and amyloid inclusions. The etiopathogenesis is a challenge because both environmental and genetic factors are implicated in muscle degeneration and a distinction has been made pre

Hypertrophic cardiomyopathy is one of the most common cardiovascular pathologies. In most cases, the disease is caused by mutations in genes encoding for sarcomeric proteins. However, high genetic heterogeneity of hypertrophic cardiomyopathy makes it difficult to interpret results of patients' genetic studies.

In the course of genetic analysis, a known pathogenic mutation p.Gln1233Ter in MYBPC3 causing hypertrophic cardiomyopathy was found only in one patient. In

Abstract The multifunctional LIM domain-binding protein Ldb1 is important in multiple developmental programs, including hematopoiesis. An evolutionarily conserved family of proteins with single-stranded DNA-binding activity, the SSBPs, has been shown to act as Ldb1 partners and augment its biological actions. We recently established that Ssbp2 and Ssbp3 were components of an E-box-GATA DNA-binding complex in murine erythroid progenitors containing the LIM-only protein Lmo2 and transcription factors Tal1, E2A, and Gata1 and showed these SSBPs stimulated E box-GATA DNA-binding activity and inhib

Abstract Abstract 1469 Poster Board I-492 The LIM domain binding protein LDB1 is an essential cofactor of LIM-homeodomain (LIM-HD) and LIM-only (LMO) proteins in hematopoiesis and other developmental programs. We have shown that LDB1 and its LIM-HD and LMO interaction partners are protected from ubiquitylation by a small family of SSBPs. Recently, we demonstrated that these SSBPs bind to LDB1 homodimers to promote formation of a ternary complex containing two molecules of LDB1 and SSBP. This was dependent on an intact LDB1 dimerization domain (DD) and produced a shift, directly or indirectly,

LDB1 (LIM-domain-binding 1) is a cofactor that participates in formation of transcriptional regulatory complexes involving transcription factors containing LIM domains as well as other factors. The amount of LDB1 protein in cells has previously been shown to be modulated by RNF12 (RING finger protein 12). RNF12 is an E3 ubiquitin ligase that can target LDB1 for poly-ubiquitination and degradation via the proteasome. We find that in HEK (human embryonic kidney)-293 cells expression of RNF12 leads to mono-ubiquitination of LDB1 and increased levels of LDB1 protein. Mutagenesis studies identified

We documented a requirement for Ldb1 in erythropoiesis in mice.

Abstract Ldb1 is a ubiquitous nuclear protein that functions by interacting with and/or recruiting specific partners (including LMO2, SCL and GATA-1) to form multi-molecular DNA-binding transcription complexes. In the hematopoietic lineage, expression of Ldb1 is highest in lineage−Sca1+c-kit+ (LSK) multipotent progenitors. Ldb1 gradually decreases as cells mature within lymphoid or granulocyte/macrophage lineages, but remains high in erythroid lineage cells.

Besides components of the CTCF/cohesin machinery, only a few nuclear factors have been studied via acute degradation to interrogate a direct/proximal role in physically connecting cis-regulatory elements (CRE).

Abstract The LIM domain-binding protein Ldb1 is known to form higher order complexes with LIM-homeodomain and LIM-only (LMO) proteins to regulate diverse developmental programs, including hematopoiesis. The level of Ldb1 is critical for its cellular roles, and its turnover is regulated by the E3 ubiquitin ligase RLIM. Single-stranded DNA-binding protein (SSDP), an Ldb1-interacting partner, is an essential gene for embryonic development and has been shown to regulate axis formation in Xenopus and wing development in Drosophila through Ldb1; however, the mechanisms by which SSDPs regulate these
