SLC22A3 and Hodgkins lymphoma: Interestingly, the expression of SLC44A1 (encoding choline transporter-like protein 1, CTL1) is up-regulated in human DLBCL and HL [52,53,54]; the expression of SLC22A3 (encoding organic cation transporter 3, OCT3) is up-regulated in follicular lymphoma (FL) and HL [52,54]; and CHKA expression is significantly increased in human DLBCL and Burkitt’s lymphoma (BL) [55,56,57,58].
