Establishment of mouse model for cutaneous squamous cell carcinoma induced by ultraviolet / 中华皮肤科杂志

Objective To establish a model for cutaneous squamous cell carcinoma by irradiation of SKH-1 hairless mice with solar-simulated ultraviolet (solar UV), and to explore the biological characteristics of the model. Methods A total of 91 SKH-1 hairless mice were randomly divided into seven experimental groups (n = 10) and seven control groups (n = 3). The mice in experimental groups were irradiated with minimal erythema dose of solar UV 4 times per week for various durations (4, 8, 12, 16, 20, 24, 28 weeks), while the control mice received no irradiation. The general status and skin appearance of mice were observed during the treatment process. Mice were killed immediately after the last irradiation at different time points and pathological examination was carried out to observe the histological changes of skin lesions. Results Papules measuring equal to or more than 1 mm in diameter began to develop in some mice in experimental group 10 weeks after the first irradiation; tumors began to appear in 39.3% (11/28) of the remaining mice in experimental group on week 20, and in 100% (10/10) of the remaining mice on week 28. The cumulative dose approximated to 26.99 J/cm2 for UVB and 242.91 J/cm2 for UVA after 28-week irradiation. No tumor was observed in the control mice. Pathological examination revealed characteristic changes of squamous cell carcinoma in 30% of the mice on week 12, 33.3% on week 16, 60% on week 20, 87% on week 24, and 100% on week 28. Conclusions Ultraviolet could induce the hyperplasia of skin in SKH-1 hairless mice, and even cause the development of cutaneous squamous cell carcinoma after prolonged irradiation.

Medicated rat serum containing Gengnianchun decoction reduces apoptosis of pheochromocytoma cells insulted by amyloid beta protein / 中西医结合学报

Objective: To investigate the effects of medicated rat serum containing Gengnianchun (GNC) decoction and its protection to pheochromocytoma cells (PC12 cells) from amyloid beta (Abeta)(25-35)-insulted apoptosis and to find the possible mechanism. Methods: Medicated rat serum was prepared by administering ovariectomized Sprague-Dawley (SD) rats with GNC decoction. The effects of medicated rat serum on viability of PC12 cells were evaluated by cell counting kit-8 (CCK-8) assay. The PC12 cells were cultured with different doses of Abeta(25-35) to induce a model of Alzheimer's disease in vitro. Then, the protective effects of medicated rat serum on Abeta(25-35)-insulted PC12 cells were evaluated by using CCK-8 assay to detect the cell viability, using Annexin V-fluorescein isothiocyanate (FITC)/propidium iodide (PI) flow cytometry to detect cell apoptosis rate and using Western blotting assay to analyze the expressions of Bcl-2, Bax and active caspase-3 proteins. Results: PC12 cells cultured with 20% medicated rat serum containing GNC decoction for 24 h or 48 h had higher viability than those cultured with normal culture medium (P<0.05). After 24- or 48-hour treatment of different concentrations of Abeta(25-35), cell viabilities were all decreased as compared with normal medium (P<0.05). Cells underwent apoptosis, which showed the neurotoxicity of Abeta(25-35). The cell apoptosis induced by Abeta 25-35 was significantly decreased in PC12 cells which were pretreated with 20% medicated rat serum or nerve growth factor (NGF) according to CCK-8 assay and Annexin V-FITC/PI flow cytometry (P<0.05). The ratio of Bax expression to Bcl-2 expression and the expression of active caspase-3 were decreased in the cells treated with medicated serum or NGF as compared with the cells cultured with Abeta(25-35) only. Conclusion: The GNC-medicated rat serum at concentration of 20% can promote viability of Abeta(25-35)-insulted PC12 cells and decrease the cell apoptosis by regulating the expressions of Bcl-2, Bax and active caspase 3.
