Definitive confirmation of liver dysfunction from low dose of #Roundup
In the new study the researchers undertook a followup protein composition profile ("proteomics") and small molecule metabolite biochemical profile ("metabolomics") investigation of the same liver samples to confirm the prediction of disease suggested by the transcriptomics gene expression profile analysis. As the proteomics and metabolomics directly measure the actual composition of the organ, these analytical methods provide a definitive assessment of its health or disease status.
Overall, metabolomics and proteomics disturbances showed a substantial overlap with biochemical hallmarks of NAFLD and its progression to steatohepatosis (serious fatty liver disease). Therefore they definitively confirm that serious liver disease has resulted from chronic ultra-low dose Roundup exposure.
The findings in detail
Proteins significantly disturbed (214 out of 1906 detected), as shown by the proteomics profiling, reflected a type of cell damage from reactive oxygen (peroxisomal proliferation), steatosis (serious fatty liver disease) and necrosis (areas of dead tissue).
The metabolomics analysis (55 metabolites altered out of 673 detected) confirmed lipotoxic (excess fatty tissue) conditions and oxidative stress. Metabolite alterations were also associated with hallmarks of serious liver toxicity.
