Pretreatment with PTH significantly inhibited the growth of luciferase-expressing BN myeloma cells in SCID-rab mice (six mice/group) 5 weeks (p<0.004), 7 weeks (p<0.004), and 9 weeks (p<0.03) after inoculation with myeloma cells (Figure 5B). This evidence concerns the gene PTH and plasma cell myeloma.
