PTTG1 and central nervous system cancer: To further explore the molecular features of the CDC20+KIF20A+PTTG1+ cell subpopulation, we first used UCell to evaluate the molecular signature levels in single‐cell glioma cohorts (Figure 4A).[21] Cell cycle‐related, DNA repair/replication, ribosome and metabolism‐related signal pathways were enriched in the CDC20+KIF20A+PTTG1+ cell subpopulation of both LGG and GBM samples.
