JAK2 and central nervous system cancer: Animal models were employed to further elucidate the function of FCGBP, with a particular focus on its impact on the Janus Kinase 2/Signal Transducer and Activator of Transcription 3 (JAK2/STAT3) signaling pathway.<h4>Results</h4>The research findings indicated that FCGBP is significantly overexpressed in glioma and is closely associated with higher tumor grades and unfavorable clinical outcomes.
