Upregulation proliferation and senescence markers in hyperplasia induced in mouse skin by sulfur mustard exposure

Chemical vesicants such as sulfur mustard (SM) can produce severe tissue damage. A time‐course study using mouse ear skin exposed to a low dose (0.08 mg) of SM resulted in excessive keratinocyte hyperplasia about three days after exposure. The abnormal cell proliferation was reminiscent of that observed in several types of cancer and potential oncogenic hyperproliferative signal molecules were examined to determine if the two systems were...
