Unique Roundup Study Shows Massive Kidney and Liver Gene Function Alterations

A new ground-breaking peer-reviewed study has been published in Environmental Health Journal that shows the levels of glyphosate-based herbicides which the general public are commonly exposed to in drinking water, altered the gene function of over 4000 genes in the livers and kidneys of rats.

The study results suggest that long-term exposure to an ultra-low, environmental dose of Roundup at an glyphosate-equivalent concentration of only 50 ppt (parts per trillion), in an established laboratory animal toxicity model system, can result in liver and kidney damage, with potential significant health implications for humans as well as domesticated animal and wildlife populations.

The study performed by Dr. Michael Antoniou’s team at King’s College London was a followup investigation of the long-term (2-year) toxicity study in rats of Roundup conducted by Dr. Gilles-Eric Seralini and colleagues (Seralini et al., 2014).

The Seralini investigation administered a commercial Roundup formulation at 0.1 ppb (parts per billion)/50 ppt (parts per trillion) glyphosate via drinking water for 2 years. Analysis at an anatomical (organ) and blood/urine biochemical level suggested a higher incidence of liver and kidney damage in the Roundup treatment group compared to the control. Liver and kidney pathologies were also present in the control group due to the advanced age of the animals, but at a lower rate of incidence.

Different patterns of gene function; i.e., which genes are turned off or on and at what level, are known to underlie health and disease status of an organ system.

The new study by Dr. Antoniou’s team investigated whether heightened liver and kidney pathology observed at an anatomical and biochemical level was reflected in the gene expression pattern. Therefore the pattern of gene function (“transcriptome”) was analysed, by comparing liver and kidney tissues from the Roundup treatment group with those of the control animals.

Dr. Antoniou stated; “The findings of our study are very worrying as they confirm that a very low level of consumption of Roundup weedkiller over the long term can result in liver and kidney damage. Our results also suggest that regulators should re-consider the safety evaluation of glyphosate-based herbicides.”animal and wildlife populations.
