Here's a reply I received:
"Hi Lucinda,
Thank you for your participation in the MBCproject, and for reaching out. Currently, there are several publications that have referenced data from the MBCproject. A few examples include the following:
Proline rich 11 (PRR11) overexpression amplifies PI3K signaling and promotes antiestrogen resistance in breast cancer. Nature Communications. 2020 Oct 30;11(1):5488.
Prevalence and mutational determinants of high tumor mutation burden in breast cancer. Annals of Oncology 2020 Mar;31(3):387-394. BioRxiv 745265 [Preprint; August 2019].
We also have an abstract that talks about the project and how we collect data which can be found here: meetinglibrary.asco.org/rec.... We are currently in the process of writing a scientific paper, and a pre-print will be available on BioRxiv in the coming months.
In addition to all of this, data from the MBCproject can be found on both publicly available databases, as well as databases that are restricted to researchers with certain qualifications, which are listed below
cBioPortal (open): cbioportal.org/study/summar...
NCI's Genomic Data Commons (partially restricted): gdc.cancer.gov/about-gdc/co...
NIH's dbGaP (partially restricted): ncbi.nlm.nih.gov/projects/g...
I hope these resources are helpful, but if you have any additional questions, please feel free to let me know. I am also happy to set up a time to discuss further over the phone if you would like.
Warmly,
Ben and the MBCproject team"
