Metformin also decreased the levels of oncogenic proteins Skp2 and β-Trcp.

Wink Re: another important player in her2 story IDd--role in herceptin resistance

Does this boil down to controlling simple sugar intake?

How does one make the following happen in real life?

"Knocking down Skp2 made cancer cell lines more susceptible to Herceptin, stifling cancer proliferation. In another mouse model, Herceptin by itself inhibited tumor growth but did not shrink tumors. With Skp2 inhibited, Herceptin treatment caused the tumors to nearly vanish in 22 days."

Re: another important player in her2 story IDd--role in herceptin resistance

As one who has been "perception resistant" from the get go this is very interesting. What are the real life implications?

Rich - I have been told that Metformin is only helpful for diabetic patients with cancer. What do you think? I have none of the typical pre diabetic characteristics either if that's any indicator.

Steph - I have cut sugar out of my diet - maybe this will help?

Loving these new insights into her2 especially, perception resistance.
