Here, we describe the use of intense pulsed light (IPL) treatment for 13 cases of erythematotelangiectatic rosacea delivered in three sessions. For two-step irradiation, after the whole face had been irradiated using conventional IPL equipment covering a wide area, localized IPL spot irradiation was performed for visibly dilated capillaries. The therapeutic effect was evaluated by image analysis using Image J and scored by 10 dermatologists using two IPL instruments in combination.

Interestingly, however, a number of non-neural tumors occasionally express high levels of TUBB3 protein, leading to a significant resistance to taxane derivatives. However, the molecular mechanisms controlling TUBB3 expression and its turnover during normal cell growth are largely unknown.

We investigated the status of human epidermal growth factor receptor (HER2) and neuronal β-tubulin isotype (class III β-tubulin; TUBB3), whose overexpression is a factor involved in resistance of tumor cells to taxane derivatives) in 32 patients with EMPD. HER2 status was evaluated by immunohistochemistry followed by fluorescence in situ hybridization, and TUBB3 status was evaluated by immunohistochemistry.

Using 7 melanoma cell lines, 2 normal neonatal human epidermal melanocyte (NHEM) cultures, and 49 primary melanomas, we investigated TUBB3 expression, its relationship to chemosensitivity to taxane derivatives, and the epigenetic mechanism controlling TUBB3 gene expression. Normal melanocytes in vitro and in vivo strongly expressed TUBB3 protein.
