tRNA half regulates cell cycle progression
Androgen receptor-positive prostate cancer cells abundantly express hormone-dependent tRNA halves, but their functions are unclear. Takuya Kawamura, Megumi Shigematsu and Yohei Kirino show that the 5′-tRNALysCUU half promotes cell cycle progression by destabilizing the mRNA of p21, a negative regulator, suggesting a general role for these molecules.
