Abstract

Background: In this study we investigated the involvement of the transcription factor STOX1A in the regulation of the cell cycle.

Methodology/principal findings: We found that several major cell cycle regulatory genes were differentially expressed upon STOX1A stimulation and knockdown in the neuroblastoma cell line SH-SY5Y. This includes STOX1A dependent differential regulation of cyclin B1 expression, a cyclin which is known to regulate mitotic entry during the cell cycle. The differential regulation of cyclin B1 expression by STOX1A is direct as shown with chromatin immunoprecipitation. Results furthermore suggest that mitotic entry is enhanced through the direct upregulation of cyclin B1 expression effectuated by STOX1A.

Conclusions: In conclusion we hereby show that STOX1A is directly involved in the regulation of the cell cycle.
