Histones, the basic proteins which compact DNA into the nucleosomal and solenoidal fibers are synthesized in correlation with DNA replication during the S-phase of the cell cycle. This behavior is controlled both at transcriptional and postranscriptional levels in higher eukaryotes and yeasts. We have found that histone synthesis in synchronized trypanosomes is controlled by fluctuations on the levels of their mRNAs. Though we cannot preclude the existence of a transcriptional regulatory mechanism, our results point to the participation of changes in the stability of histone mRNAs as a regulatory mechanism of their levels during the cell cycle in Trypanosoma. We have also found a postranscriptional regulatory mechanism which could be acting at the translational level. These results show both similarities and differences between Trypanosoma and higher eukaryotes regarding the expression of their histone genes.
