T-box genes encode transcription factors that play critical roles in generating the vertebrate body plan. In many developmental fields, multiple T-box genes are expressed in overlapping domains, establishing broad regions in which different combinations of T-box genes are coexpressed. Here we demonstrate that three T-box genes expressed in the zebrafish mesoderm, no tail, spadetail, and tbx6, o...
High-mobility group (HMG) B proteins are eukaryotic DNA-binding proteins characterized by the HMG-box functional motif. These transcription factors play a pivotal role in global genomic functions and in the control of genes involved in specific developmental or metabolic pathways. The filamentous ascomycete Podospora anserina contains 12 HMG-box genes. Of these, four have been previously charac...
The MADS-box genes encode transcription factors with key roles in plant growth and development. A comprehensive analysis of the MADS-box gene family in bread wheat (Triticum aestivum) has not yet been conducted, and our understanding of their roles in stress is rather limited. Here, we report the identification and characterization of the MADS-box gene family in wheat. A total of 180 MADS-box g...
Genome sequencing efforts of the last decade have produced a large amount of data, which has enabled whole-genome comparative analyses in order to locate potentially functional elements and study the overall patterns of phylogenetic conservation. In this paper we present a statistically based method for the characterization of these patterns in mammalian DNA sequences. We have applied this appr...
Sulfur mustard (SM) is a strong alkylating and mutagenic compound that targets humanairway system. We considered the expression of Forkhead box M1 (FOXM1) and apolipoproteinE (APOE) genes, which are responsible for cell proliferation, differentiation, tumorigenesis,and increased risk of lung cancer, in the lung bronchial tissue of patients exposed to SM.After performing pulmonary functional tes...
Maize was domesticated from its wild ancestor, teosinte, in southern Mexico between ~6,250 and ~10,000 years ago. The domestication of maize resulted in an extensive phenotypic change in female inflorescence (ear) structures from teosinte. MADS-box genes encode transcription factors which are key regulators of plant inflorescence and flower development. We examined DNA sequence variation in 32 ...
BACKGROUND Activation of the immune system affects the circadian clock. Tumor necrosis factor (TNF) and Interleukin (IL)-1β inhibit the expression of clock genes including Period (Per) genes and the PAR-bZip clock-controlled gene D-site albumin promoter-binding protein (Dbp). These effects are due to cytokine-induced interference of E-box mediated transcription of clock genes. In the present st...
