Molecules called long non-coding RNAs (lncRNAs) have been implicated in breast cancer but exactly why they cause metastasis and tumour growth has been little understood, until now. Scientists at The MD Anderson Cancer Center report that hedgehog, a unique cell signalling pathway known to contribute to many types of cancer, may be behind breast cancer metastasis. This molecular message service works with the lncRNA known … Continue reading Hedgehog signalling pathway for breast cancer identified.
