This result is also similar to Abmb effect to the breast cancer cells, where the protein only causes growth arrest at low concentrations as demonstrated with the MCF-71,2 and MDA-MB-231 cells.17 MBP is widely known to bind specifically breast cancer cells, which are abundantly decorated by mannose-type glycans.20,21 Mannose and lectin interaction is also well known in regulation of immunity.15 This study provides further support for the relationship between immunity and cancer, in which cellular immunity response is able to counter internal infection and deal with cancerous cells.22 The gene discussed is MBP; the disease is breast carcinoma.
