Quantitative μCT data showed a higher level of BV/TV, average trabecuar thickness (Tb.Th), trabecular bone density (Tb.N), and a lower level of average distance between trabecular bone (Tb.Sp) in the myeloma-bearing Ciita-knockout mice than in the wild-type mice (Fig. 2d, g). The gene discussed is CIITA; the disease is plasma cell myeloma.
