- Nitrogen Mustard was the first Chemotherapy Drug (based on WWI mustard gas) 1 atom different
- Nitrogen Mustard is still being used for
Leukemia, Lymphoma, Hodgkin's disease, Lung cancer, Breast cancer - Nitrogen Mustard has major side effects (but not everyone gets ALL of them)
Nausea and vomiting, Hair loss, Mouth sores, Darkening of veins, Loss of fertility - This study shows that Vitamin D reduces side effects in mice
- Previous studies have shown that many chemo doses can be reduced 3X with Vitamin D

“Mustargen, mustine and mechlorethamine hydrochloride are all forms of nitrogen mustard”
“Nitrogen mustard drugs are extremely toxic. In fact, they can actually cause cancer as well as help cure it.”

DNA alkylating agents like nitrogen mustard (NM) are easily absorbed through the skin and exposure to such agents manifest not only in direct cellular death but also in triggering inflammation. We show that toxicity resulting from topical mustard exposure is mediated in part by initiating exaggerated host innate immune responses. Using an experimental model of skin exposure to NM we observe activation of inflammatory dermal macrophages that exacerbate local tissue damage in an inducible nitric oxide synthase (iNOS)-dependent manner. Subsequently these activated dermal macrophages reappear in the bone marrow to aid in disruption of hematopoiesis and contribute ultimately to mortality in an experimental mouse model of topical NM exposure. Intervention with a single dose of 25-hydroxyvitamin D3 (25(OH)D) is capable of suppressing macrophage-mediated iNOS production resulting in mitigation of local skin destruction, enhanced tissue repair, protection from marrow depletion, and rescue from severe precipitous wasting. These protective effects are recapitulated experimentally using pharmacological inhibitors of iNOS or by compounds that locally deplete skin macrophages. Taken together, these data highlight a critical unappreciated role of the host innate immune system in exacerbating injury following exposure to NM and support the translation of 25(OH)D in the therapeutic use against these chemical agents.
