The prediction model of the PKD3/PD-L1 positive feedback loop. PKD3/PD-L1 drives EMT through ERK/STAT1/3 signalling, thus promoting tumour growth and metastasis. PKD3, protein kinase D3; ERK, extracellular signal-regulated kinase; STAT, signal transducer and activator of transcription; PD-L1, programmed death ligand-1; PD-1, programmed cell death protein 1
