Primary or acquired resistance to therapeutic agents is a major obstacle in the treatment of cancer patients. Cervical cancer is the fourth leading cause of cancer deaths among women worldwide and, despite major advances in cancer screening and treatments, many patients with advanced stage cervical cancer have a high recurrence rate within two years of standard treatment, with drug resistance being a major contributing factor. The development of cancer cell lines with acquired resistance to therapeutic agents can facilitate the comprehensive investigation of resistance mechanisms, which cannot be easily performed in clinical trials. This study aimed to create three novel and robust cervical cancer cell lines (HeLa, CaSki, and SiHa) with acquired resistance to a fibroblast growth factor receptor (FGFR) tyrosine kinase inhibitor (PD173074). All three drug-resistant (DR) cell lines overexpressed FGFR1, FGFR2, FGF2, FGF4, and FGF7 proteins that were also localized to the nucleus. In addition, the DR cells had a significantly more aggressive phenotype (more migratory and proliferative, less apoptotic) compared to the parental cell lines. These novel DR cervical cancer cells are a critical tool for understanding the molecular mechanisms underpinning drug resistance and for the identification of potential cervical cancer biomarkers. Moreover, the availability of such DR cell lines may facilitate the development of more effective therapeutic strategies using FGFR inhibitors in combination with other agents that target pathways responsible for acquired resistance to FGFR inhibitors.
