Guys, any thoughts on isoflavon?

I'm trying to understand how this isoflavon thing can lower our blood glucose levels, like it does on rats...

From what I've read, it increases insulin secretion, or due to it's estrogenic properties, it affects the beta cells... but how does it make these happen???

can someone take a look at the articles and explain to me in simpler words since I've had a really tough time understanding these? thank you )

here are the articles i've read though, some of them:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3678366/

https://www.ncbi.nlm.nih.gov/pubmed/15650341

https://www.ncbi.nlm.nih.gov/pubmed/19083447

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2849033/

some of the experiments are done on rats though, well most of them, actually. but on laboratory rats, that are similar to humans, supposedly....

Thanks!!
