For example, MGAT4A expression was high in gastrointestinal tissues, while MGAT4B was ubiquitously expressed.[53] In pancreatic cancer, MGAT4A was downregulated due to the promoter methylation, while MGAT4B was overexpressed.[54] Based on the IHC data from Human Protein Atlas endometrial cancer database, MGAT4A was overexpressed mainly in EC cells and MGAT4B was expressed in tumor stroma (Figure S2I, Supporting Information). The gene discussed is MGAT4B; the disease is familial pancreatic carcinoma.
