IL24 and cancer: IL24 was originally discovered to harbor a specific anticancer activity without affecting normal cells (Menezes et al. 2018), including apoptosis induction, anti-angiogenesis mechanisms, halting invasion, cancer stem cell elimination, radio-sensitization, chemo-sensitization and immune tolerance (Ma et al. 2016; Panneerselvam et al. 2013; Su et al. 2003).
