ABSTRACT
Transmembrane glycoprotein integrins play crucial roles in biochemical processes, and by their inhibition or activation, different signal pathways can be disrupted, leading to abnormal physiological functions. We have previously demonstrated the inhibitory effect of glyphosate herbicide's active ingredient on cell adhesion and its αvß3 integrin antagonist effect. Therefore, it appeared particularly exciting to investigate inhibition of glyphosate and its metabolites on a wider range of Arg-Gly-Asp (RGD) binding integrins, namely αvß3, α5ß1 and αllbß3. Thus, the purpose of this study was to assess how extended the inhibitory effect observed for glyphosate on the integrin αvß3 is in terms of other RGD integrins and other structurally or metabolically related derivatives of glyphosate. Five different experimental setups using enzyme-linked immunosorbent assays were applied (i) αvß3 binding to a synthetic polymer containing RGD; (ii) αvß3 binding to its extracellular matrix (ECM) protein, vitronectin; (iii) α5ß1 binding to the above polymer containing RGD; (iv) αllbß3 binding to its ECM protein, fibrinogen and (v) αvß3 binding to the SARS-CoV-2 spike protein receptor binding domain. Total inhibition of αvß3 binding to RGD was detected for glyphosate and its main metabolite, aminomethylphosphonic acid (AMPA), as well as for acetylglycine on α5ß1 binding to RGD.
