Also, a recent study showed that similar to CIB1, CIB2 negatively regulates oncogenic signalling in ovarian cancer via its interaction with sphingosine kinase 1 (SK1), a regulator of the cellular balance between pro‐apoptotic and pro‐survival sphingolipids (Zhu et al, 2017). The gene discussed is SPHK1; the disease is ovarian carcinoma.
