Comparative RNA-seq profiling of human HER2+ JIMT1-BR3 and JIMT1-BR3-LM4 breast cancer cells
Listed in NCBI GEO
A human HER2-positive leptomeningeal colonization model, JIMT1-BR3-LM4, was established by intrathecal injection of the JIMT1-BR3 HER2+ cell line, which already formed parenchymal brain metastases and occasional leptomeningeal metastases.
Description
In this study, bulk RNA sequencing was performed to define transcriptomic differences between parental JIMT1-BR3 cells and the leptomeningeal-tropic derivative JIMT1-BR3-LM4. These data provide a resource for identifying gene expression changes associated with HER2-positive breast cancer leptomeningeal colonization.
