摘要
The retinoblastoma protein, RE, is an important tumour suppressor. Recent studies have shown that it inhibits the synthesis of both rRNA and tRNA by RNA polymerases I and III. Suppression of these important determinants of biosynthetic capacity might provide a mechanism for restraining cell growth. Loss of this control could constitute one step towards tumour progression.
