New Target May Be Eyed in Kids' Brain Cancer
States conducted a high resolution genomic screen of CNS-PNET tumors and found that a DNA segment that contains a group of 54 microRNA (miRNA) genes was present in many copies in aggressive tumor cells. The specific miRNAs from this C19MC group can stimulate

Lab Study Slows Breast Cancer Spread to Bone in Mice
This study also revealed that a specific microRNA cluster, 17 through 92, is associated expression and breast cancer metastasis. The microRNA cluster responded to ROCK inhibition to researchers focused on the role of microRNAs in gene expression," Liu said. The
