The researchers identified that interferon-induced protein with tetratricopeptide repeats 1 (IFIT1), FAST kinase domains 2 (FASTKD2), phosphatidylinositol-5-phosphate 4-kinase type-2 beta (PIP4K2B), AT-rich interactive domain-containing protein 1B (ARID1B), and solute carrier family 25 member 33 (SLC25A33) were overexpressed in the tumor tissue of the initial biopsy from patients who achieved complete response to neoadjuvant chemoradiotherapy. The gene discussed is IFIT1; the disease is neoplasm.
