Hedgehog signaling pathway for breast cancer identified

Molecules called long non-coding RNAs (lncRNAs) have been implicated in breast cancer but exactly why they cause metastasis and tumor growth has been little understood...until now. Scientists at The University of Texas MD Anderson Cancer Center report that hedgehog, a unique cell signaling pathway known to contribute to many types of cancer, may be behind breast cancer metastasis. This molecular message service works with the lncRNA known as BCAR4 giving the genetic green light for tumor growth. Read more here.
