We generated lentiviral constructs to overexpress and silence HOXB8 in CRC cell lines, and examined their biological functions through MTT, wound healing, colony and transwell, expression of signal transducer and activator of transcription 3 (STAT3) and epithelial–mesenchymal transition (EMT) related factors through western-blot. The gene discussed is STAT3; the disease is colorectal carcinoma.
