HIF1A and neoplasm: This work evaluated the expression of HIF1A, SLC2A1, LDHA, CA9, SLC16A3, and BSG transcripts in cervical cancer cell lines with and without HPV 16, compared to the HPV-negative C-33A tumor cell line, SiHa, with one to two integrated copies per cell of the HPV 16 genome, and Ca Ski with 600 integrated copies per cell of the HPV 16 genome.
