A larger number of statistically-significant ‘Compartment 2’ differences were observed when the MCF10A cells were compared with cancer lines including ST3GAL3, ST3GAL6, ST6GAL1, ST6GALNAC2, ST6GALNAC5, ST6GALNAC6, ST8SIA1, ST8SIA4, ST8SIA5, ST8SIA6 (Fig 2A and 2B). The gene discussed is ST8SIA4; the disease is cancer.
