Protein kinase R and dsRNAs, new regulators of mammalian cell division
This finding will provide important clues to understanding the process of tumor formation and the mechanism for suppressing cancer since the abnormal cell division marks the early events of cancer development. For the first time, the IBS research team has found that during mitosis, the cellular dsRNAs activate PKR, an enzyme previously known as a trigger of immune response during virus infection. Activated PKR then regulates protein synthesis and orchestrates mitotic processes…
