Overview of Gene Research
Gspt1, also known as G1 to S phase transition 1, is a key translation termination factor. It interacts with eRF1 to facilitate translation termination, playing a vital role in protein synthesis, a fundamental biological process [1,2].
Studies have shown that Gspt1 is significantly overexpressed in various cancer tissues and cells, including acute myeloid leukemia, MYC-driven lung cancer, liver cancer, and glioblastoma [1,2,4,5]. In acute myeloid leukemia, drugs that degrade Gspt1 via the CRL4CRBN ubiquitin ligase lead to impaired translation termination, activation of the integrated stress response pathway, and TP53-independent cell death, sparing normal hematopoietic stem cells [3]. In glioblastoma, depletion of Gspt1 using a cereblon modulator or knockout cells leads to enhanced apoptosis and longer survival in mice with transplanted tumors [5].
In conclusion, Gspt1 is essential for translation termination. Its overexpression in multiple cancers makes it a promising anti-tumor target. The use of Gspt1-degrading drugs and gene knockout models in in vivo studies has provided insights into its role in cancer, offering potential new strategies for cancer treatment [1,2,3,5].
