GFP Reporter Cell Line - SIHA

SIHA cells are a human cervical squamous cell carcinoma–derived cell line widely used as an in vitro model for studying cervical cancer biology and HPV-associated oncogenic transformation. These cells exhibit epithelial morphology, robust proliferative capacity, and molecular characteristics typical of high-grade cervical carcinoma, including dysregulation of cell cycle control, apoptosis resistance, and enhanced invasive potential. SIHA cells are particularly valuable for investigating the molecular mechanisms underlying HPV-driven carcinogenesis and tumor progression in cervical epithelial tissues. The GFP Reporter Cell Line – SIHA is generated by stable integration of a green fluorescent protein (GFP) reporter construct driven by pathway-responsive promoters or transcription factor–specific regulatory elements into the parental SIHA background, enabling real-time visualization and quantitative analysis of cellular signaling activity and gene expression while preserving the intrinsic biological features of the original cell line.

The GFP Reporter Cell Line – SIHA is widely applied in cervical cancer research, HPV-related signaling studies, and live-cell imaging–based drug screening. Unlike luciferase-based systems, the GFP reporter allows direct fluorescence-based detection of cellular activity, enabling real-time monitoring of dynamic biological processes at the single-cell level without substrate addition. This model is particularly useful for studying key signaling pathways involved in cervical carcinogenesis, including PI3K/AKT, MAPK/ERK, NF-κB, Wnt/β-catenin, and JAK/STAT pathways, as well as HPV-mediated regulatory mechanisms affecting cell proliferation and survival. The GFP signal provides a stable and non-invasive readout suitable for high-content imaging, time-lapse microscopy, and quantitative fluorescence analysis. This cell line is commonly used in compound screening, mechanistic studies of tumor progression, and evaluation of gene regulation dynamics, making it a valuable tool for both basic research and translational studies in cervical cancer biology.
