Research

The regulation and fidelity of gene expression is of paramount importance for the maintenance and differentiation of all living organisms. Our laboratory studies the production and quality control of RNA in eukaryotic cells (S. cerevisiae, mouse and human) and its contribution to gene expression regulation. A main focus of the laboratory is to understand the molecular principles dictating the sorting of newly transcribed RNA into a productive pathway involving its packaging with protein and cellular transport vs. a destructive pathway leading to RNA turnover. We believe that a thorough understanding of these relationships will also position us to better understand any putative function of the pervasive transcription of eukaryotic genomes.

Laboratory efforts can roughly be divided into four research topics:

· Delineation of nuclear human RNA decay pathways and their regulatory capacities

· Distinguishing non-functional from functional non-coding RNA transcription events

· Shaping of human transcriptomes by nonsense-mediated decay (NMD)

· Relationships between RNA synthesis and decay in S. cerevisiae

From 2005-2015 Torben Heick Jensen was heading the Danish National Research Foundation-funded ‘Centre for mRNP Biogenesis and Metabolism’. These, and other, efforts are now continued via funding from the European Research Council (ERC), the Danish Council for Independent Research, the Novo Nordisk foundation, the Lundbeck Foundation and the Danish Cancer Society. The THJ laboratory is also part of the iSEQ Centre for Integrative Sequencing (www.iseq.au.dk).

New nuclear RNA retention activity discovered

Gene expression involves mRNA transport from its place of synthesis to the cytoplasm where protein translation occurs. However, many non-coding RNA species do not follow this flow and new data now demonstrate how cells prevent the unwanted export of RNA and instead ensure nuclear degradation.

Researchers reveal dual role for human RNA decay factor

Researchers at Aarhus University have characterized the human RNA decay factor ZC3H18 and discovered its unanticipated role in the production of protein-coding RNA. The new study, published this week in Cell Reports, therefore reveals a double-faced activity of ZC3H18 in nuclear RNA fate decisions.
