  This paper combines immunogold TEM, confocal immunocytochemistry, coimmunoprecipitation and Western blots to prove the metabolon type regulation of NKCC, the ubiquitous cotransport protein and its responsiveness to small osmotic perturbations.  This novel association of FAK with integrin and NKCC as the force sensor in the cascade builds on our 2005 paper and consolidates the role of FAK pY407 phosphorylation as central to the regulation.  Reviewers remarks: " provides evidence of an exciting and novel role for the focal adhesion kinase signaling system in osmoregulation", " the immuno-EM, in particular, is beautiful and very convincing " and " The results provided important contribution to understand the signal pathways related to NaCl secretion "{NSERC, StFX UCR, HRSDC}

  Hypotonic shock from the basal (blood) side only produces abrupt inhibition of Cl- secretion and  hypertonic shock does the reverse.  In this collaborative project, we used Western analyses, pharmacology and immunocytochemistry with colocalization to reveal a kinase cascade that terminates on the cotransporter Na+,K+,2Cl- cotransporter NKCC, including FAK (focal adhesion kinase) and stress associated protein kinase (SPAK).  This is the first time FAK has been associated with ion transport and cell volume regulation.  The osmosensor that may be a key to understanding regulatory volume decrease we think involves FAK as a regulator protein that permits a kinase cascade ending with SPAK that directly phosphorylates NKCC.  Reviewer #1:"This is an important work...." {NSERC, CFI, James Chair Endowment}

3. Marshall, W.S., E.M. Lynch* and R.R.F. Cozzi. Redistribution of immunofluorescence of CFTR anion channel and NKCC cotransporter in chloride cells during adaptation of the killifish Fundulus heteroclitus to sea water.  J. exp. Biol. 205: 1265-1273 (2002). PDF

  Immunocytochemistry and confocal microscopy was used here to trace where in the ion transporting cells were the main Cl transporting proteins CFTR and NKCC.  The paper clearly showed changes in transporter distribution that coincide with the appearance of Cl transepithelial transport at 24h-48h after transfer to sea water.  This slow redistribution is not simple fusion of membrane vesicles but rather appears to involve de novo expression of transporters and insertion in the plasma membrane as well as removal of the old transporter, a real “retooling” of existing chloride cells. {NSERC, CFI}

4. Marshall, W.S., S.E. Bryson and T. Luby*.  Control of epithelial Cl- secretion by basolateral osmolality in the euryhaline teleost, Fundulus heteroclitusJ. exp. Biol. 203:1897-1905. (2000). PDF

  Hypotonic shock inhibits Cl- secretion involving protein tyrosine kinase but apparently not calcium.  This paper led to Daborn's work with pavement cell-chloride cell interactions and collaboration with E.K. Hoffmann.  It was the first to address the paradox that here transepithelial Cl- transport is inhibited by hypotonic shock, whereas regulatory volume decrease is normally associated instead with increases Cl- channel activity. {NSERC + UCR}

This paper used eight sampling times (one hour to 4 weeks) and twelve measured variables, molecular through physiological, to build for the first time a clear picture of the sequence and relationships between seawater adaptational events in an estuarine teleost.  Important time lines of events (e.g. cortisol peaks at 1 hour and kfCFTR expression increases at 8h+) were established which led to many new interesting hypotheses being generated.  This paper showed that measurement of many variables in a time course to be a much more powerful approach than the study of fully acclimated animals.

6. Marshall, W.S., R.M. Duquesnay*, J.M. Gillis*, S.E. Bryson and C.M. Liedtke. Neural modulation of salt secretion in teleost opercular epithelium by a2-adrenergic receptors and inositol 1,4,5-trisphosphate. J. exp. Biol 201:1959-1965 (1998). {NSERC + James Chair Research Grant} Here we used a unique nerve-epithelium in vitro preparation to measure neural effects on Cl- secretion and revealed that salt secretion is under neural control by the autonomic nervous system. It strengthened the conclusion of Ca2+ mediation by detecting a peak in IP3.  It supports the novel idea that changes in salinity experienced by estuarine fish are NOT necessarily stressful, rather that they can be handled with same facility as are many “higher” autonomic functions, such as sweating in primates.

7. Marshall, W.S., S.E. Bryson, A. Midelfart and W.F. Hamilton. Low conductance anion channel activated by cAMP in teleost Cl‑ secreting cells. Am. J. Physiol. 268:R963‑R969 (1995). This paper reveals presence of the anion channel CFTR in fish. It has finally allowed molecular descriptions of chloride cell operation and is unique in its cellular regulation, making the work of importance to Cystic Fibrosis research.  It paved the way for kfCFTR sequencing (see Singer et al 1998, below).

8. Marshall, W.S., S.E. Bryson and D. Garg*. a2‑adrenergic inhibition of chloride transport by opercular epithelium is mediated by intracellular Ca2+. Proc. Nat. Acad. Sci. U.S.A. 90:5504‑5508 (1993).

This paper shows a unique Ca2+‑mediated inhibition by a2‑receptors. Most receptors of this type in the vertebrates are mediated differently, via decrease in cAMP.  Hence our results run counter to the  accepted dogma at the time, but appear to be robust, as other examples have now been found.
