Serum contain many types of RNA molecules such as protein-coding messenger RNAs (mRNAs), miRNAs, piRNAs, transfer RNAs (tRNAs) and other miscellaneous non-coding RNA molecules. Regulatory ncRNAs, and in particullar microRNAs (miRNA), have been implicated in cancer and many other diseases and are thus promising biomarkers.
We have initiated two large small non-coding RNA cancer biomarker projects. These projects are led by the Cancer Registry of Norway (CRN) , and in close collaboration with the Norwegian Sequencing Center (NSC) at Oslo University Hospital (OUS), Saarland University, and bioinformatics core facilities at the University of Oslo.
Pre-diagnostic samples from the Janus Serum Bank (JSB), cancer data from the registry and health survey data provides a unique oppertunity to discover early detection cancer biomarkers.
The project is funded by the Research Council of Norway.
About 30.000 Norwegians are diagnosed with cancer annually and cancer is the second leading cause of death overall in Norway.
Colorectal cancer is one of the most common cancers and has increased rapidly in Norway since the 1960s in both men and women. Symptoms from colon cancer often appear at a late stage, when prognosis is uncertain or poor.
Similarly, lung cancer is the predominant cause of cancer-related death in men and women, and the incidence rates among women are still increasing. Due to lack of efficient strategies for screening or early diagnosis, the prognosis is generally poor.
Aim of research
The overall research aim is to investigate sncRNAs as early detection biomarkers. The long-term goal is to exploit such biomarkers in cancer screening.
We have produced sncRNA expression profiles from more than 2000 cancer cases and 600 healthy controls using pre-diagnostic serum samples from the Janus Serum Bank, on an Illumina HiSeq platform at NSC.
Our data set contain quality assured expression profiles that can be accessed by national and international research groups. We have reached an average sequence depth of 18 million sequences, and identified more than 600 unique miRNAs per sample in addition to other noncoding RNAs.

How to get access to data
The datasets can be accessed by national and international research groups after approval of a research plan by the data access committee at CRN and approval from REK (Regional Committees for Medical and Health Research). The data access committee includes senior researchers Hilde Langseth PhD and Trine B. Rounge PhD, Director Giske Ursin and senior lawyer Hilde Olav.
For data requests please send an email to Cecilie Bucher-Johannessen.
Some administrative costs will follow with data access. The price will depend on overall complexity of the data request.
