Última ABC transporters in Mycoplasma hyopneumoniae and Mycoplasma synoviae: insights into evolution and pathogenicity Genet. Mol. Biol. Nicolás,Marisa Fabiana; Barcellos,Fernando Gomes; Nehab Hess,Pablo; Hungria,Mariangela. ABC transporters represent one of the largest superfamilies of active membrane transport proteins (MTPs) with a highly conserved ATPase domain that binds and hydrolyzes ATP, supplying energy for the uptake of a variety of nutrients and for the extrusion of drugs and metabolic wastes. The complete genomes of a non-pathogenic (J) and pathogenic (7448) strain of Mycoplasma hyopneumoniae, as well as of a pathogenic (53) strain of Mycoplasma synoviae have been recently sequenced. A detailed study revealed a high percentage of CDSs encoding MTPs in M. hyopneumoniae strains J (13.4%), 7448 (13.8%), and in M. synoviae 53 (11.2%), and the ABC systems represented from 85.0 to 88.6% of those CDSs. Uptake systems are mainly involved in cell nutrition and some might be...

DA; VALENTE,RAPHAEL C.; SILVA,JOYLE M.C. DA; PAIVA,LUCIANA S. DE; RUMJANEK,VIVIAN M.. Abstract Glucocorticoids are produced and released by the adrenal gland and become elevated in response to stress. Although glucocorticoids are well known for their immunosuppressive effects, less is known about their effects on B cells. ABCB1 is an efflux pump expressed in both cancer and normal cells, modulating the gradient of various metabolites, including hydrocortisone. Our goal was to evaluate the effect of this glucocorticoid on murine B cell differentiation and whether sensitivity to hydrocortisone could be related to ABCB1 activity in vivo. C57BL/6 mice received one or three consecutive i.p. injections of hydrocortisone (70, 140 and 200 mg/kg/day). ABCB1 activity was evaluated via the rhodamine-123 transport and inhibited by cyclosporin A in...

Mol. Biol. Amaral,Alexandre Morais do; Saito,Daniel; Formighieri,Eduardo Fernandes; Rabello,Edenilson; Souza,Adriane N. de; Silva-Stenico,Maria Estela; Tsai,Siu Mui. Pleiotropic drug resistance (PDR) proteins, a subfamily of the ATP-binding cassette (ABC) transporters, have been recently shown to play a role in plant defense against biotic and abiotic stresses. However, nothing is known about their expression in citrus. To investigate the occurrence of PDR homologues in citrus species, we have surveyed EST sequences from different tissues and conditions of the Citrus Expressed Sequence Tags (CitEST) database, through sequence similarity search analyses and inspections for characteristic PDR domains. Multiple sequence alignments, prediction of transmembrane topology and phylogenetic analysis of PDR-like proteins were additionally performed. This study allowed the identification of nine putative proteins showing...
