(Submitter supplied) DNA methylation at cytosine bases of eukaryotic DNA (5-methylcytosine, 5mC) is a heritable epigenetic mark that can regulate gene expression in health and disease. Enzymes that metabolize 5mC have been well-characterized yet the discovery of endogenously produced signaling molecules that regulate DNA methyl-modifying machinery have not been described. Herein, we report that the free radical signaling molecule nitric oxide (NO) can directly inhibit the Fe(II)/2-OG-dependent DNA demethylases ten-eleven translocation (TET) and Human AlkB homolog 2 (ALKBH2). more...

(Submitter supplied) Iron serves as a cofactor for enzymes involved in several steps of protein translation, but the control of translation during iron limitation is not understood at the molecular level. Here, we report a genome-wide analysis of protein translation in response to iron deficiency in yeast using ribosome profiling. We show that iron depletion affects global protein synthesis and leads to translational repression of multiple genes involved in iron-related processes. more...

(Submitter supplied) Mycobacterium abscessus is one of the common clinical non-tuberculous mycobacteria (NTM) which can cause severe skin infections. 5-Aminolevulinic acid photodynamic therapy (ALA_PDT) is an emerming effective antimicrobial medication. To explore whether ALA_PDT can treat M. abscessus infections, we found that ALA_PDT can kill M. abscesses via colony forming unit method. ALA_PDT promoted ferroptosis-like death of M. more...

(Submitter supplied) Heme is an erythrocyte-derived toxin that drives disease progression in hemolytic anemias. During hemolysis, specialized bone marrow-derived macrophages with a high heme-metabolism capacity orchestrate disease adaptation by removing damaged erythrocytes and heme-protein complexes from the blood and supporting iron recycling for erythropoiesis. Here, we performed single-cell RNA sequencing with RNA velocity analysis of GM-CSF-supplemented mouse bone marrow cultures to assess myeloid differentiation under heme stress. more...

(Submitter supplied) Abstract: Natural communities of microbes inhabiting amphibian skin, the skin microbiome, are critical to supporting amphibian health and disease resistance. To enable the pro-active health assessment and management of amphibians on Army installations and beyond, we investigated the effects of acute (96h) munitions exposures to Rana pipiens (leopard frog) tadpoles and the associated skin microbiome, integrated with RNAseq-based transcriptomic responses in the tadpole host. more...

(Submitter supplied) One major mode of action of DNA hypomethylating agents such as decitabine (DAC) is reactivation of gene expression and induction of differentiation. Prompted by observations of differentiation induction in leukemic myeloid cells and upregulation of fetal hemoglobin (HbF) in adult patients suffering from hemoglobinopathies, we aimed at systematically investigating the potential and significance of DAC for in vitro and in vivo induction of erythroid differentiation and HbF expression. more...

(Submitter supplied) Iron plays the central role in the oxygen transport by the erythrocyte as a constituent of heme and hemoglobin. The importance of iron and heme also resides in their regulatory roles during erythroblast maturation. The transcription factor Bach1 may be involved in their regulatory roles since it is inactivated by direct binding of heme. To address whether Bach1 is involved in the responses of erythroblasts to iron status, low iron conditions that induced severe iron deficiency in mice were established. more...

(Submitter supplied) Campylobacter jejuni is a leading cause of bacterial diarrheal disease and a frequent commensal of the intestinal tract of poultry and other animals. For optimal growth and colonization of hosts, C. jejuni employs two-component regulatory systems (TCSs) to monitor environmental conditions and promote proper expression of specific genes. We analyzed the potential of C. jejuni Cjj81176_1484 (Cjj1484) and Cjj81176_1483 (Cjj1483) to encode proteins of a cognate TCS that influences expression of genes possibly important for C. more...

(Submitter supplied) Eukaryotic chromosomes replicate in a temporal order known as the replication-timing program. In mammals, replication timing is cell type-specific with at least half the genome switching replication timing during development, primarily in units of 400-800 kilobases ('replication domains;), whose positions are preserved in different cell types, conserved between species, and appear to confine long-range effects of chromosome rearrangements. more...

The ability to survive and grow under osmotic stress conditions in particular appears to be important for both growth in certain foods and food associated environments as well as for host infection. To characterize the contributions of transcriptional regulators important for stress response and virulence (i.e., Sigma B - σB and PrfA), we initially analyzed three L. more...
