Figure 4From: Hypoxia-inducible factor-1α polymorphisms and TSC1/2 mutations are complementary in head and neck cancersWestern blot for HIF-1α, TSC1, TSC2, OS-9 and Actin. Cells were grown under normoxic conditions, harvested and analyzed using SDS-PAGE followed by Western blotting as described in Methods. The representative lanes are as follows: a) SCC-4a, b)SCC-9, c)SCC-15, d) SCC-25b, and e)UMBSCC-11.Back to article page
