currently are looking at novel agents against<br />
multiple myeloma (MM). The NCI-sponsored<br />
phase I/II clinical trial is examining arsenic trioxide<br />
+ ascorbic acid in the treatment of refractory/<br />
relapsed MM. Initial results demonstrate that this<br />
combination is effective against myeloma that is<br />
resistant to standard chemotherapy (including<br />
thalidomide) with acceptable toxicity. The laboratory<br />
component of these studies seeks to understand<br />
how arsenic kills myeloma, how ascorbic<br />
acid potentiates that killing, how myeloma cells<br />
become resistant to arsenic, and which host<br />
(i.e., patient) factors may help the myeloma<br />
survive in the bone marrow.<br />

HIGHLIGHTS/DISCOVERIES<br />
• Direct activation of PKC causes normal human<br />
hematopoietic CD34 + stem cells to differentiate<br />
into DC.<br />
• PKC activation causes many myeloid leukemias<br />
to differentiate into immunologically functional<br />
“leukemic” DC. These cells have potential utility<br />
as “cellular” anti-leukemia vaccines.<br />
• Specific intracellular signaling pathways downstream<br />
of PKC activation control specific aspects<br />
of DC differentiation.<br />
• Arsenic trioxide + ascorbic acid is an effective<br />
combination in the treatment of refractory/relapsed<br />
myeloma.<br />
