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 />
