Progesterone regulates female reproductive function predominantly through two nuclear progesterone receptors (PRs), PR-A and PR-B. During human parturition myometrial PR expression is altered to favour PR-A, which activates pro-labour genes. We have previously identified histone H3 lysine 4 trimethylation (H3K4me3) as an activator of myometrial PR-A expression at labour. To further elucidate th...
OBJECTIVE Lacunar infarctions are mainly due to 2 microvascular pathologies: lipohyalinosis and microatheroma. Little is known about risk factor differences for these subtypes. We hypothesized that diabetes and glycated hemoglobin (HbA(1)c) would be related preferentially to the lipohyalinotic subtype. METHODS We performed a cross-section analysis of the brain MRI data from 1,827 participants...
PURPOSE The putative association between erbB-2 overexpression and favorable response to anthracyline-based therapy in breast cancer is controversial, and the mechanism unclear. We sought to determine whether coamplification and overexpression of the topoisomerase IIalpha gene, near erbB-2 on chromosome 17, and a known anthracycline target, may underlie the association. EXPERIMENTAL DESIGN Th...
Proteorhodopsin (PR) is present in half of surface ocean bacterioplankton, where its light-driven proton pumping provides energy to cells. Indeed, PR promotes growth or survival in different bacteria. However, the metabolic pathways mediating the light responses remain unknown. We analyzed growth of the PR-containing Dokdonia sp. MED134 (where light-stimulated growth had been found) in seawater...
The nucleotide sequence of the nucleoprotein gene of influenza A/NT/60/68 was established after using improved cloning methods to obtain full length cDNA clones in pBr322. The gene is 1565 residues long and codes for a basic protein of 498 amino acids. There are only 30 amino acid differences between it and the homologous sequence in A/PR/8/35, all occurring as point mutations. Assuming a commo...
Efficacy of luteal support from single daily administration of Crinone((R)) 8% (progesterone gel) was tested in 43 women in an IVF programme with historical pregnancy rates >50%. Results were compared with those achieved in 46 women concurrently undergoing IVF and receiving 50 mg i.m. progesterone, and with historical data. Pregnancy rates (PR) were evaluated approximately 2 weeks after undergo...
Pti4 is induced by ethylene and salicylic acid, and its product is phosphorylated by the Pto kinase.
The tomato Pti4 gene encodes a transcription factor that was identified on the basis of its specific interaction with the product of the Pto disease resistance gene in a yeast two-hybrid system. We show here that the Pti4 protein specifically binds the GCC-box cis element, which is present in the promoter region of many pathogenesis-related (PR) genes. Expression of the Pti4 gene in tomato leav...
Steroid hormone receptors act directly in the nucleus on the chromatin organization and transcriptional activity of several promoters. Furthermore, they have an indirect effect on cytoplasmic signal transduction pathways, including MAPK, impacting ultimately on gene expression. We are interested in distinguishing between the two modes of action of progesterone receptor (PR) on the control of ge...
Systemic acquired resistance (SAR) is a nonspecific defense response in plants that is associated with an increase in the endogenous level of salicylic acid (SA) and elevated expression of pathogenesis-related (PR) genes. To identify mutants involved in the regulation of PR genes and the onset of SAR, we transformed Arabidopsis with a reporter gene containing the promoter of a beta-1,3-glucanas...
STUDY OBJECTIVES Pulmonary rehabilitation (PR) improves exercise tolerance in COPD patients. Tiotropium is a once-daily, inhaled anticholinergic bronchodilator that provides sustained 24-h improvements in airflow and lung hyperinflation reduction. We hypothesized that ventilatory mechanics improvements from tiotropium would permit enhanced ability to train muscles of ambulation and therefore au...
