20. TRF1 knockdown suppressed Nek2- induced lagging chromosomes, suggesting that TRF1 may affect kinetochore capture by mitotic spindles. PMID: 24091727
21. these findings suggested that PinX1 may maintain telomere integrity by regulating TRF1 stability and that hTERT may act as both a positive and a negative regulator of TRF1 homeostasis in a PinX1-dependent manner. PMID: 24415760

24. TRF1 is an important factor in the colorectal tumor progression and maybe a diagnostic factor PMID: 23268632
25. This improved model also reveals extensive indirect readout, which suggests that telomere recognition by TRF1 will be affected by changes to DNA helical parameters such as bending. PMID: 23702294
26. Results indicate that beta-TrCP1 is involved in the negative regulation of TRF1. PMID: 23583392
