This study investigates the effects of glyphosate (GLY) and its metabolite AMPA on cytoprotective and detoxification mechanisms in haemocytes of Mytilus galloprovincialis. Cells were treated in vitro with 0.1 and 1.0 mu g/L GLY, 0.1 mu g/L, 0.1 and 1.0 mu g/L AMPA, or two mixtures GLY+AMPA (0.1 mu g/L GLY + 0.1 mu g/L AMPA, 1.0 mu g/L GLY + 1.0 mu g/L AMPA). GLY and AMPA increased MXR efflux activity and modulated expression of the ABCB transcript encoding a MXR related ABC transporter P-glycoprotein. The mixtures GLY+AMPA reduced efflux activity with ABCB down-regulation (at 1 mu g/L GLY/AMPA). Modulation of lysosomal and immune related transcripts generally agree with known effects of the chemicals on these physiological functions. Given their cumulative action as chemosensitizers of the MXR system, and their interactive effects on haemocyte parameters, glyphosate and AMPA at environmental concentrations should be addressed as a concern factor for the biological vulnerability of marine habitats.

Abstract

This study investigates the effects of glyphosate (GLY) and its metabolite AMPA on cytoprotective and detoxification mechanisms in haemocytes of Mytilus galloprovincialis. Cells were treated in vitro with 0.1 and 1.0 mu g/L GLY, 0.1 mu g/L, 0.1 and 1.0 mu g/L AMPA, or two mixtures GLY+AMPA (0.1 mu g/L GLY + 0.1 mu g/L AMPA, 1.0 mu g/L GLY + 1.0 mu g/L AMPA). GLY and AMPA increased MXR efflux activity and modulated expression of the ABCB transcript encoding a MXR related ABC transporter P-glycoprotein. The mixtures GLY+AMPA reduced efflux activity with ABCB down-regulation (at 1 mu g/L GLY/AMPA). Modulation of lysosomal and immune related transcripts generally agree with known effects of the chemicals on these physiological functions. Given their cumulative action as chemosensitizers of the MXR system, and their interactive effects on haemocyte parameters, glyphosate and AMPA at environmental concentrations should be addressed as a concern factor for the biological vulnerability of marine habitats.
