While analysis of microarray data for primary breast cancers revealed significant lower c-Fos mRNA levels in tumor samples with low LASP1 expression (p<0.001, Supplementary Table S2), the analysis of our microarray data set pointed to up-regulation of c-Fos transcription by LASP1 depletion (Supplementary Table S1). Here, LASP1 is linked to breast carcinoma.
