PHC3 and neoplasm: To preclude mislocalisation of the Golgi as the consequence of cells undergoing cell division (Thyberg and Moskalewski, 1999), we co-stained intestinal epithelial sections with an antibody against the mitotic marker phospho-histone 3 (PH3) – tumour cells displayed delocalised Golgi in the absence of detectable levels of PH3 (Fig. S1B).
