The telomerase essential N-terminal domain promotes DNA synthesis by stabilizing short RNA-DNA hybrids. PDF available through Get Fulltext Research

Akiyama, Benjamin M Parks, Joseph W Stone, Michael D

Published in Nucleic acids research

Telomerase is an enzyme that adds repetitive DNA sequences to the ends of chromosomes and consists of two main subunits: the telomerase reverse transcriptase (TERT) protein and an associated telomerase RNA (TER). The telomerase essential N-terminal (TEN) domain is a conserved region of TERT proposed to mediate DNA substrate interactions. Here, we h...

Metal contamination of home garden soils and cultivated vegetables in the province of Brescia, Italy: implications for h...

Prolonged industrial emissions increase median metal concentrations and most soluble fractions (BCR F1+F2) in home garden soils near ferroalloy plants. Areas near ferroalloy plant sites had spinach Cd and Pb metal concentrations several-fold above maximum standard references. We recommend thorough washing of vegetables to minimize metal exposure.

Cancer/Testis Antigen PASD1 Silences the Circadian Clock. PDF available through Get Fulltext Research

Michael, Alicia K Harvey, Stacy L Sammons, Patrick J Anderson, Amanda P Kopalle, Hema M Banham, Alison H Partch, Carrie L

Published in Molecular cell

The circadian clock orchestrates global changes in transcriptional regulation on a daily basis via the bHLH-PAS transcription factor CLOCK:BMAL1. Pathways driven by other bHLH-PAS transcription factors have a homologous repressor that modulates activity on a tissue-specific basis, but none have been identified for CLOCK:BMAL1. We show here that the...

Hematopoietic development at high altitude: blood stem cells put to the test.

Zovein, Ann C Forsberg, E Camilla

Published in Development (Cambridge, England)

In February 2015, over 200 scientists gathered for the Keystone Hematopoiesis meeting, which was held at the scenic Keystone Resort in Keystone, Colorado, USA. The meeting organizers, Patricia Ernst, Hanna Mikkola and Timm Schroeder, put together an exciting program, during which field leaders and new investigators presented discoveries that spanne...

Vibrio cholerae Response Regulator VxrB Controls Colonization and Regulates the Type VI Secretion System. PDF available through Get Fulltext Research

Cheng, Andrew T Ottemann, Karen M Yildiz, Fitnat H

Published in PLoS pathogens

Two-component signal transduction systems (TCS) are used by bacteria to sense and respond to their environment. TCS are typically composed of a sensor histidine kinase (HK) and a response regulator (RR). The Vibrio cholerae genome encodes 52 RR, but the role of these RRs in V. cholerae pathogenesis is largely unknown. To identify RRs that control V...

C-Myb(+) erythro-myeloid progenitor-derived fetal monocytes give rise to adult tissue-resident macrophages. PDF available through Get Fulltext Research

Hoeffel, Guillaume Chen, Jinmiao Lavin, Yonit Low, Donovan Almeida, Francisca F See, Peter Beaudin, Anna E Lum, Josephine Low, Ivy Forsberg, E Camilla ...

Published in Immunity

Although classified as hematopoietic cells, tissue-resident macrophages (MFs) arise from embryonic precursors that seed the tissues prior to birth to generate a self-renewing population, which is maintained independently of adult hematopoiesis. Here we reveal the identity of these embryonic precursors using an in utero MF-depletion strategy and fat...

Identification and characterization of VpsR and VpsT binding sites in Vibrio cholerae.

Zamorano-Sánchez, David Fong, Jiunn C N Kilic, Sefa Erill, Ivan Yildiz, Fitnat H

Published in Journal of bacteriology

The ability to form biofilms is critical for environmental survival and transmission of Vibrio cholerae, a facultative human pathogen responsible for the disease cholera. Biofilm formation is controlled by several transcriptional regulators and alternative sigma factors. In this study, we report that the two main positive regulators of biofilm form...
