Vulvar cancer is rare, mostly afflicting women aged 60 and older. The cancer is often preceded by a common vulvar rash, Lichen sclerosis, that is usually treated with the ultra-potent corticosteroid, clobetasol propionate. This treatment may, in turn, be associated with vulvar carcinogenesis. Quiescence, a common characteristic of stem cells, is a reversible state of growth arrest. Our results suggest that clobetasol is causing UMSCV-4 vulvar carcinoma cells to enter quiescence, and may allow them to evade the standard treatments that target rapidly proliferating populations. Furthermore, when these cells are removed from clobetasol and re-exposed, they proliferate at higher levels. …

Increased expression of human leukocyte antigen (HLA) allows tumor cells to be more easily detected by the immune system. In previous research, epigenetic modifiers including the histone deacetylase inhibitor 3 (HDAC3), RGFP966, has been shown to decrease PD-L1 expression. PD-L1 expression inhibits T cell cytotoxicity, and decreasing it can enhance the immune response. We hope to elucidate whether or not HLA-ABC expression similarly decreases upon exposure to the HDAC3 inhibitor which would be detrimental to immune detection. Two breast cancer cell lines that express HLA-ABC are MCF-7 and MDA-MB-231. Our initial results show that HLA-ABC is expressed on the MDA-MB-231 …
