In Vitro | In vitro activity: Etretinate(Ro 10-9359) is a second-generation retinoid to treat severe psoriasis; has been replaced by acitretin, a safer metabolite of etretinate. Cell Assay: The HSC-5 cells are plated in 96-well plates at a density of 1.5×103 per 100 μL and used for experiments. Preliminary experiments are performed to determine the effective dose and cytotoxicity of etretinate. The cells are incubated for 72 h with etretinate at concentrations of 5, 10, 25 and 50 nmol/L [dissolved in saline containing 0.0001% dimethyl sulfoxide (DMSO)]. The cells are then incubated for a further 2 h with or without 200 μmol/L ALA (Sigma). Each plate is then irradiated using a metal halide lamp at doses of 10, 20, 40 and 80 J/cm2. |

In Vivo | There is a significant decrease in mean dermal thickness (P < 0.05) and changes in collagen bundles in the etretinate-treated mice group for a 28-day period compared to control groups. TUNEL assay shows that the density of TUNEL-positive cells in the dermis of etretinate-treated mice for a 14-day period is significantly increased (P < 0.05). The ratio of procollagen α 1 (I) chain to β actin mRNA from etretinate-treated mice for a 1-day period decreased significantly compared to that of the control mice, but the ratio from etretinatetreated mice for a 14-day period increased significantly (P < 0.05). Etretinate reduces dermal thickness, and suppresses the appearance of skin lesions by inducting apoptosis and perhaps regulation of cytokine expression in MRL/lpr mice. |
