(Submitter supplied) ERG and FLI1 are important regulators of angiogenesis, but their role in lymphatic vasculature is less known. The goal of this study was to determine the role of ERG and FLI1 in postnatal lymphangiogenesis and their involvement in SSc lymphatic system defects. IF were used to detect ERG and FLI1 in SSc and healthy controls (HC) skin biopsies. Human lymphatic endothelial cells (LECs) were used in cell culture experiments. more...

(Submitter supplied) Epithelial cells are the first point of contact for bacteria entering the respiratory tract. Streptococcus pneumoniae is an obligatory human pathobiont of the nasal mucosa, carried asymptomatically but also the cause of severe pneumoniae. The role of the epithelium in maintaining homeostatic interactions or mounting an inflammatory response to invasive S. pneumoniae is currently poorly understood. However, studies have shown that chromatin modifications, at the histone level, induced by bacterial pathogens interfere with the host transcriptional program and promote infection. In this study, we demonstrate that S. pneumoniae actively induces di-methylation of histone H3 on lysine 4 (H3K4me2), which persists for at least 9 days upon clearance of bacteria with antibiotics. We show that infection establishes a unique epigenetic program affecting the transcriptional response of epithelial cells, rendering them more permissive upon secondary infection. Our results establish H3K4me2 as a unique modification induced by infection, distinct from H3K4me3, which localizes to enhancer regions genome-wide. Therefore, this study reveals evidence that bacterial infection leaves a memory in epithelial cells after bacterial clearance, in an epigenomic mark, thereby altering cellular responses for subsequent infections. Transcriptome analysis aimed at testing whether cells respond differently in the primary (1°) and secondary (2°) infection. Differential gene expression and gene set enrichment analysis performed.

(Submitter supplied) The deposited microarray data were generated in a study that integrated the gene expression profiles and metabolic responses of Caco2 cells incubated with Bifidobacterium infantis subsp. infantis and Salmonella enterica subsp. enterica sv. Typhimurium. The aim of this study was to investigate the interaction of B. infantis, S. Typhimurium, and host cells (Caco2) in the course of infection to understand the molecular mechanics of probiotic-pathogen-host interactions.

(Submitter supplied) The transcription factor p73, a member of the p53 tumor-suppressor family, regulates cell death and also supports tumorigenesis, though the mechanistic basis for the dichotomous functions is poorly understood. We report here the identification of an alternate transactivation domain (TAD) located at the extreme carboxyl (C)-terminus of TAp73β, a commonly expressed p73 isoform. Mutational disruption of this TAD significantly reduced TAp73β’s transactivation activity, to a level observed when the amino (N)-TAD that is similar to p53’s TAD is mutated. more...

(Submitter supplied) The study explored the impact of Specific Immunotherapy on patients with Atopic Dermatitis sensitized to house dust mites by analyzing the transcriptomes of T regulatory cells before and after treatment. Result found that effective SIT is associated with distinct gene expression changes in Treg cells, particularly increased expression of Treg markers and RORC, a gene linked to immune regulation. These results indicate that successful SIT may enhance the function of Treg cells expressed RORC and help restore immune balance in these patients.

(Submitter supplied) Highly specialized, acid-secreting PCs are one of many epithelial lineages that line the gastric epithelium. Even though PCs are functionally and structurally distinct from other lineages in the stomach, the molecular mechanisms that govern their specification and maturation from the gastric stem cells are relatively unknown. We used microarray analysis to interrogate transcriptional changes that occur in regenerating PCs and to identify candidate regulators of PC fate specification and maturation.

(Submitter supplied) In human colon cancer, the malignant component of tumor tissues often contains multiple sub-types of cancer cells, whose transcriptional profiles and surface marker phenotypes correspond to those of the epithelial lineages that are found in normal colonic crypts (e.g., goblet cells, enterocytes, LGR5+ columnar basal cells). Among those various sub-types of malignant cells, those characterized by a surface marker phenotype that is characteristic of epithelial stem/progenitor cells residing at the bottom of colonic crypts (EpCAM+, CD44+, CD166+) are enriched in cells with "cancer stem cell" (CSC) properties, such as self-renewal (i.e., the capacity to sustain the formation of new tumors upon serial xeno-transplantation in immune-deficient animals) and multi-lineage differentiation (i.e., the capacity to sustain the formation of other cell-types, thus reconstituting the heterogeneous population of the parent tumors from which they have been isolated). more...
