Fig. 6: PEAK1 expression in MSCs drives the production of secreted factors that promote breast cancer cell proliferation/survival and lapatinib resistance in vitro.

From: A SNAI2-PEAK1-INHBA stromal axis drives progression and lapatinib resistance in HER2-positive breast cancer by supporting subpopulations of tumor cells positive for antiapoptotic and stress signaling markers

a Schematic for generating TB CAF or C3H MSC conditioned media (CM) for analysis on breast cancer cell growth/survival over 48 h in vitro. b Cell viability analysis of BT474 cells treated with mock or TB122 CM. c Cell viability analysis of BT474 cells treated with mock CM or CM from the indicated shRNA derivatives of C3H10T1/2 cells. d Cell viability analysis of BT474 cells treated with mock CM or CM from the indicated shRNA derivatives of C3H10T1/2 cells and treated with vehicle control or the indicated dose of lapatinib. *, ***, or **** indicates a p value < 0.05, 0.001 or 0.0001, respectively, as determined by a One-Way or Two-Way ANOVA w/multiple comparisons post-test.
