SLC6A3 and non-Hodgkin lymphoma: In the NAcc core, DAT expression was selectively decreased in juvenile, but not adult, NHL rats (juvenile, 0.56±0.04, n = 18; adult, 1.15±0.41, n = 6) compared to CTR rats (juvenile, 1.00±0.16, n = 8; adult, 1.07±0.16, n = 10; F1,45 = 8.71, P = 0.005 for lesion types; F1,45 = 1.74, P = 0.194 for ages; F1,45 = 0.22, P = 0.641 for lesion types×ages; P = 0.044 for juvenile NHL vs. CTR rats with post-hoc test; Fig. 6d).
