Myxococcus xanthus generates diadenosine tetraphosphates (Ap4 A) and diadenosine pentaphosphates (Ap5 A) under various stress conditions. M. xanthus lysyl-tRNA synthetase (LysS) efficiently synthesizes Ap4 A from ATP, Ap5 A from ATP and adenosine tetraphosphate (Ap4 ), and Ap4 from ATP and triphosphate. To identify other M. xanthus enzymes that can catalyze Ap4 A and Ap4 synthesis, 15 M. xanthus aminoacyl-tRNA synthetases (aaRSs), four acyl-CoA synthetases (Acys), three acetyl-CoA synthetases (Aces), phosphoglycerate kinase (Pgk), and adenylate kinase (Adk) were expressed in Escherichia coli and examined for Ap4 A or Ap4 synthetase activity using ATP or ATP and triphosphate as substrates...

Lactotroph adenoma, also called prolactinoma, is the most common pituitary tumor but little is known about its pathogenesis. Mouse models of prolactinoma can be useful to better understand molecular mechanisms involved in abnormal lactotroph cell proliferation and secretion. We have previously developed a prolactin receptor deficient ( Prlr -/- ) mouse, which develops prolactinoma. The present study aims to explore the natural history of prolactinoma formation in Prlr -/- mice, using hormonal, radiological, histological and molecular analyses to uncover mechanisms involved in lactotroph adenoma development...

Estrogen is reported to be involved in mammary tumorigenesis. To unveil metabolic signatures for estrogen-induced mammary tumorigenesis, we carried out serum metabolomic analysis in an estrogen-induced mammary tumor model, female August Copenhagen-Irish/Segaloff (ACI/Seg) rats, using liquid chromatography-mass spectrometry. In contrast to the control group, all rats with an implanted 17β-estradiol (E2) pellet developed mammary tumors during this experiment. E2 treatment significantly suppressed body weight gain...

PURPOSE: The failure of chronic therapy with antibiotics to clear persistent respiratory infection is the key morbidity and mortality factor for patients with chronic lung diseases, primarily due to the presence of biofilm in the lungs. It is hypothesised that carbon sources, such as mannitol, could stimulate the metabolic activity of persister cells within biofilms and restore their susceptibility to antibiotics. The aims of the current study are to: (1) establish a representative in vitro model of Pseudomonas aeruginosa biofilm lung infection, and (2) investigate the effects of nebulised mannitol on antibiotic efficacy, focusing on ciprofloxacin, in the eradication of biofilm...
