Michael Theis Solgaard Jensen

During his PhD studies, Michael T. Solgaard J. investigated how human cells regulate the synthesis of ribosomal proteins, and by extension, ribosome biogenesis. Owing to mTORC1-mediated phosphorylation of LARP1, the human cell is capable of controlling the expression of TOP mRNAs, which encode nearly all ribosomal proteins needed for ribosome biogenesis. By studying the effect of LARP1 phosphorylation on TOP mRNA abundance and translation, Michael T. Solgaard J. examined the mechanisms that enable the mTORC1-LARP1 axis to oversee ribosome biogenesis.

This research characterizes the acute details regarding phosphorylation patterns that control LARP1, and it also contributes to the understanding of LARP1-mediated control of mRNA abundance.

The PhD study was completed at the Department of Molecular Biology and Genetics, Faculty of Natural Sciences, Aarhus University
