What news on soya milk would that be?

Some quotes:

1) From Oz, but quoting Torsten, on degradeability of glyphosate
protection genes:

Nice flower you have there Oz. Natural?
Sorry to disturb, while you are making these important points.

A news item, that ticked in. Really nothing, just Madness.

Really good stuff. It shows that (despite apprearances ho, ho) Torsten
is still a logical scientist (at least on occasiona.) :-)

NB Snips all over the place.

Both variants of the GOX protein (GOX and GOXv247) are rapidly
degraded in simulated gastric fluid (GF) and simulated intestinal fluid
(IF). After a fifteen-second incubation in GF, both variants have less
than 90% of their initial protein epitopes by western blot analysis.
Enzyme activity loss is also greater than 90% in both GOX variants when
assayed after a 1-minute incubation in GF. Similar results are seen in
simulated IF. Western blot assays show that both variants are greater
than 90% degraded by 30-second incubation in IF. However, the enzyme
activity assays show that the GOX activity lasts longer in IF than
variant GOXv247. After a 10-minute IF incubation, the activity
decreased to about 48% of initial for GOX whereas GOXv247 was already
greater than 90% inactive.
Two findings, found in the in vitro digestibility studies, that are
remarkable a GOXv247 displays a more rapid degradation in the IF
compared to unaltered GOX, apparently due to the single amino acid
substitutions; and antibody recognition is lost prior to a significant
loss of enzyme activity indicating that western blots may not always
accurately track functional protein degradation.

OK, so it's very quickly and readily digested. I am hardly amazed.

The acute oral toxicity test of bacterially-derived GOX and GOXv247
proteins showed no test substance related deaths at doses of 91.3
milligrams per kilogram (mg/kg) and 104 greek-mg/kg respectively.
Expression data on the GOX protein expressed in corn grains ranges from
undetectable levels to a high of 11.70 micro grams per gram (mg/g)
freshweight. This indicates that it would require 8,547 kg corn grain
per kg bodyweight to receive the 100 mg/kg dose that was administered
to the mice.

OK, it's highly non-toxic as well as rapidly degraded. Hey, what more do
you want? Heck the estrogens in the soya are probably thousands (maybe
more) of times more hazardous.

Seems like Oz & Tracy were pretty well spot on except we didn't assume
quite such a spectacularly safe product.

Thanks Torsten, you are a gentleman. This has progressed the knowledge
in the group.
