Table 2.

The response to everolimus alone for cell lines and PDCC used in the study.

Cell lines and PDCC	IC50 concentration to everolimus	Respone to everolimus
MCF7	5 nM	Sensitive
Hs578T	6.8 nM	Sensitive
BT474	60 nM	Resistant
MDA-MB-231	500 nM	Resistant
ABC-82T	>500 nM	Resistant
ABC-16TX1	>1000 nM	Resistant

Notes: Sensitive to everolimus is defined as IC50 concentration < 50 nM

Resistance

to everolimus is defined as IC50 concentration > 50 nM.
