From: Caveolin-1 expression is elevated in claudin-low mammary tumor cells
Western blot of Cav-1 protein in 4 independent wild type (WT) mammary tissue sample, 4 independent primary mammary tumor (PMT) tissue samples induced by transgenic overexpression of IGF-IR, and 4 independent recurrent spindle tumor (RST) tissue samples which developed after the downregulation of the IGF-IR transgene. β-actin served as a loading control
