GABBR2 and breast carcinoma: We show that pharmacological modulation of GABBR2 does not affect proliferation of tumour or non-neoplastic cells (Additional File 1: Fig.S12g) whilst its activation promotes migration (Fig. 4f top) and invasion of the tumour cells (Fig. 4g top and Additional File 1: Fig.S12h) in keeping with previous finding in breast cancer [66].
