Abstract:
:Autophagy is an intracellular multi-step catabolic degradation process that involves the degradation and recycling of cellular proteins and cytoplasmic damaged organelles to maintain cellular homeostasis and reduction of metabolic stress. Numerous studies have indicated the importance of autophagy in cancer, but the role of autophagy in human skin squamous cell carcinoma (SSCC) development and response to therapy it is still unclear. In the present study, we investigated the role of autophagy in SSCC and the relationship with chemotherapy sensitivity. The present study demonstrated that autophagy related gene the microtubule-associated protein 1 light chain 3 (LC3) expression was low in SSCC. The negative correlation with Bcl2 and survivin, and the chemotherapy drug 5-FU increased the level of autophagy and the autophagy inhibitor 3-MA inhibited this effect in SSCC cells, time- and dose-dependently. When SSCC cells were treated first with 3-MA and then with 5-FU, the inhibition of proliferation, migration, invasion and apoptosis of SSCC cells was enhanced. Our results suggested the possibility of autophagy as a potential target in SSCC therapy and 3-MA and 5-FU combination treatment may be an effective SSCC therapy via autophagy modulating.
