Preclinical drug screening identifies novel stratified treatment options according to the consensus molecular subtypes of colorectal cancer
In two recent publications (Eide PW et al. Sci Rep; Sveen A*, Bruun J* et al. Clin Cancer Res), scientists in the Lothe lab., Department of Molecular Oncology, have identified novel potential treatment strategies for colorectal cancer (CRC), guided by the consensus molecular subtypes (CMS). Combining algorithm development, for translation of CMS classification to preclinical models, with drug screening of classified cell lines and patient-derived xenografts (PDXs) in collaboration with the Finnish Institute for Molecular Medicine and Vall d´Hebron Institute of Oncology, a potential to overcome chemoresistance in the poor prognostic CMS4-mesenchymal group was identified by combination therapy with 5-fluorouracil (5-FU) and HSP90 inhibitors.

Michael Bretthauer er Månedens forsker i Helse Sør-Øst
Viljen til nytenkning har resultert i en strålende forskerkarriere. Tilfeldighetene gjorde at Bretthauer som nyutdannet lege fra Tyskland takket ja til turnusjobb på Porsgrunn sykehus på slutten av 90-tallet. Her spesialiserte han seg innen indremedisin og fordøyelsessykdommer. Knappe 20 år etter er han Europas eneste redaktør i et av verdens fremste medisinske tidsskrifter.
Dr. Jarle Bruun’s research profiled in the 2016 National report from the Regional Health Authorities
The report highlights clinically relevant research, and projects ongoing in the K.G. Jebsen Colorectal Cancer Research Centre were selected from the South-Eastern Norway Regional Health Authority. Specifically, Dr. Jarle Bruun's paper identifying the gene Regulator of Chromosome Condensation 2 (RCC2) as functionally important in colorectal cancer, and furthermore that changes of RCC2 at the DNA and protein level can identify clinically distinct subgroups of patients with inferior survival.
Epigenetic markers stratify colorectal cancer patients within a genetically defined poor prognostic patient group
Vedeld and co-workers show that the CpG Island Methylator Phenotype (CIMP) carry prognostic value across stages. Patients with microsatellite stable tumors with BRAF V600E mutations, defining a poor prognostic subgroup, can be further subdivided by the CIMP status. This is a study from the Lind and Lothe groups in collaboration with the clinical research team of Arild Nesbakken.
Clinically important genetic heterogeneity in colorectal cancers with microsatellite instability
Microsatellite instability (MSI) defines a small subgroup of approximately 15% of colorectal cancers (CRC) which currently receives much attention due to its overall good response to immune-checkpoint inhibition.

Encouraging new procedures in Annals of Internal Medicine
Using carbon dioxide rather than room air to distend the colon during endoscopy reduces postprocedure discomfort. Yet, today, most colonoscopies worldwide still use air insufflation. The authors speculate about why adoption of this effective, inexpensive, “low-tech” innovation has been so slow.
