SINGER, T.D.*; SCHULTE, P.M.; University of Waterloo*; University of British Columbia: Osmoregulation and control of CFTR expression in teleost fish Homologues of the Cystic Fibrosis Transmembrane conductance Regulator (CFTR) play an important role in osmoregulation of seawater adapted teleost fish. CFTR, an apically located chloride channel, interacts with basolaterally located Na+,K+-ATPase and a Na+K+2Cl– co-transporter […]

LARSEN, E. H.*; AMSTRUP, J.; WILLUMSEN, N.J.; University of Copenhagen, Denmark: Function, regulation and cloning of CFTR in toad (Bufo bufo) skin mitochondria rich cells Amphibian skin absorbs NaCl and H2O by epidermal cells and secretes fluid by subepidermal glands. CFTR is implicated in both functions. The epidermis contains Na transporting principal cells and Cl […]

SCHULTE, P.M.*; SINGER, T.D.; Univ. of British Columbia; Univ. of Waterloo: Comparative genomic sequence analysis of CFTR The cystic fibrosis transmembrane conductance regulator (CFTR) has a highly regulated expression pattern, but the sequences regulating its transcription remain poorly characterized. We have used a genomics approach (phylogenetic footprinting) to characterize regulatory elements involved in CFTR expression. […]

MARSHALL, W.S.; LYNCH, E.M.; HOWARD, J.A.; EPEGA, A.; COZZI, R.R.F.; St. Francis Xavier U.: CFTR expression patterns in a euryhaline teleost fish. Cystic Fibrosis Transmembrane conductance Regulator (CFTR) in the euryhaline killifish Fundulus heteroclitus (kfCFTR) is an anion channel expressed in gill, opercular epithelium, brain and intestine. We established that CFTR was the channel responsible […]

CUTLER, C.; CRAMB, G.; Univ. of St Andrews, UK: A comparative analysis of CFTR in teleost fish. The cloning of CFTR cDNA sequences from a number of teleost species allows an analysis of both sequence and expression data to be performed. Analysis of teleost CFTR sequences shows, that as a group,teleost CFTR orthologues are approximately […]

Meeting Abstract S3.4  Sunday, Jan. 4  The role of insect adipokinetic hormones in locomotion, development and reproduction LORENZ, M.W.*; GAEDE, G.; University of Bayreuth; University of Cape Town matthias.lorenz@uni-bayreuth.de Many insect hormones have a direct or indirect influence on metabolic events in insects. One of the true metabolic hormones is the adipokinetic hormone (AKH) which has been […]

Meeting Abstract S3.6  Sunday, Jan. 4  The hormonal control of seawater performance in anadromous fish MCCORMICK, Stephen D.; USGS, Conte Anadromous Fish Research Center, Turners Falls, MA USA mccormick@umext.umass.edu Anadromy is a life history strategy in which fish move from fresh water to seawater as juveniles and then return to fresh water to breed. Anadromy developed early […]

Meeting Abstract S3.7  Sunday, Jan. 4  Social behaviour in context: how animals adjust their behaviour to the social environment OLIVEIRA, R.F.; ISPA, Lisboa, Portugal ruiol@ispa.pt Animals interact with each other frequently and these interactions modulate subsequent interactions among them and with other group members. Thus, animals must fine-tune the expression of their social behaviour to the social […]

Meeting Abstract S3.3  Sunday, Jan. 4  Phenotypic Integration and Independence: Hormones, Performance, and Response to Environmental Change KETTERSON, E.D.*; ATWELL, J.W; Indiana Univ.; Indiana Univ. ketterso@indiana.edu The concepts of hormonal pleiotropy, physiological epistasis, and hormonal correlations raise many unanswered questions with respect to the links between hormones and whole-animal performance. One such question is the functional importance […]

Meeting Abstract S3.8  Sunday, Jan. 4  Interactions between hormones and energetics as mediators of performance and reproductive success MOORE, Ignacio/T*; HOPKINS, William/A; Virginia Tech; Virginia Tech itmoore@vt.edu How an animal performs in its natural environment ultimately determines its reproductive success. Thus, performance traits are often a target of selection, both natural and sexual. While many studies have […]
