SEPTIN6 and cancer: In addition, the roles and mechanisms of many other key cancer-related genes that have been detected by RNA sequencing and validated by qRT-PCR in distinct types of cancer need to be further investigated, such as TMEM14C (transmembrane protein 14C), SEPT6 (septin 6), and ENOSF1 (enolase superfamily member 1), as shown in Fig. 4.
