Transcriptome profiling of SUM159 and derivatives with different metastasis capability

Triple negative breast cancer cell line SUM159 labeled with triple reporter (TR, TK-GFP-fLUC) injected into Nude mice via mammary fat pad and tail vein injection. Tumor progression is monitored by in vivo bioluminescent imaging. Tumors from mammary and lung were isolated and cultured. These derivatives cells are further tested for their capability to develop mammary primary tumor and metastasis in lung and bone in mice. The total RNA samples are extracted from the panel of SUM159 and derivatives and the transcriptome profiles are determined by microarray. The correlation of transcriptome of the cells to metastasis capability indicated candidate genes and regulatory pathways of metastasis of TNBC. Transcriptome correlation to metastasis capability of a panel of 7 cells from SUM159 origin.
