So, does ingesting GMO crops alter gene expression?

Op I took an organic vegetable production course at my university (plant science major). The professor has studied this field and told us that it does not harm you in any way such as this. But I must point out he is a lobbyist for Monsanto....

Well the article seems to say that eating crops alters gene expression. So you better stop eating food.

I took a molecular biology class once where the professor did a lecture on GMOs (bt toxin in plants and etc..) and how they're completely safe.

So.. probably, yes. Saying GMOs are dangerous is probably not a good way to advance your career in the current climate.

>>5560805

But, has this aspect of GMOs been tested? Maybe eating something where it's genes are altered could negatively affect the organism that eats it. We don't know unless data is collected. Doesn't seem too farfetched of an idea though, does it?

You're being incredibly defensive. Why do GMOs get you all riled up? It's a legitimate /sci/ topic.

I also had a professor abroad who did a study where they put wild type wheat and GMO wheat in a mouse cage, and the mice didn't even nibble the GMO stuff. So, from that, we can infer that there could be other unexpected differences between the wild type and the mutant strain.

I'm not saying GMOs are bad; I'm saying every new technology has the possibility to cause unexpected results.

You have some reading to do.

What exactly did I say that makes you think that? Of course, it's not actually what you think; it's just more extreme rhetoric and an attempt to paint yourself as someone with authority.

Considering domesticated wheat and GMO wheat have a lot more in common than wild wheat and domesticated wheat, it's possible those mice would also avoid domesticated wheat. Sounds like a pretty flawed experiment to me if they didn't take this into account.

So basically, instead of us just breeding rice to eat, the rice is actually breeding us to propagate it's genes. This is indeed an interesting twist on reality!

Wild type does not mean wheat growing in the wild; it means the strain that isn't genetically modified (i.e. not the mutant strain).

It's a bit of a misnomer in this case.

We may have evolved to anticipate these influences, or been selected for that as a species.

Our current model of inheritance and gene expression is an enormous simplification of the intricacies and complexities involved in transcribing DNA and translating it into proteins.

It is very difficult to formulate precise models of gene expression from the point of transcribing DNA into RNA to the point where the resulting protein is transported to where it is used by your body tissue; there is no standardized process for all genes as it is in a human factory. There are many intricacies involved such that the mechanics by which two genes are expressed may be very different.

The fact is, biology requires simplified models and making many assumptions, same as physics and chemistry.
What you learn about genetics and heredity in university bio class is very much a simplified general model, not a precise and consistent biological system.

I am certain there is much about our genetics we will be surprised.

I took a class on GMOs back in uni. While it's relatively healthy for human consumption, they still have a lot of problems associated with them like horizontal gene transfer with microbes in the soil? We don't know how that would pan out...

Wait. RNA is not membrane soluble so if it's circulating around in blood how can it go into liver cells to block transcripts? Further, if the miRNA isn't capped, which it clearly isn't if it's just a fragment of RNA, then why isn't it broken down by RNAase even if it gets through a membrane channel?

I'm not really liking this article, needs more info.
