Abstract:
Messenger RNA (mRNA) translational control plays a pivotal role in regulating cellular proteostasis under physiological and pathological conditions. Dysregulated mRNA translation is pervasive in cancer, in which protein synthesis is elevated to support accelerated cell growth and proliferation. Consequently, targeting the mRNA translation machinery has emerged as a therapeutic strategy to treat cancer. In this Perspective, we summarize the current knowledge of translation dysregulation in cancer, with emphasis on the eukaryotic translation initiation factor 4F complex. We outline recent endeavors to apply this knowledge to develop novel treatment strategies to combat cancer.
Insights
Messenger RNA (mRNA) translation control is crucial for cell balance and is often disrupted in cancer, leading to uncontrolled growth. Targeting mRNA translation, particularly the eukaryotic translation initiation factor 4F complex, offers a promising new strategy for cancer therapy.
