Tidskriftsartikel (refereegranskat)abstract
- Genome-wide association studies have been successful in elucidating the genetic basis of colorectal cancer (CRC), but there remains unexplained variability in genetic risk. To identify new risk variants and to confirm reported associations, we conducted a genome-wide association study in 1,701 CRC cases and 14,082 cancer-free controls from the Finnish population. A total of 9,068,015 genetic variants were imputed and tested, and 30 promising variants were studied in additional 11,647 cases and 12,356 controls of European ancestry. The previously reported association between the single-nucleotide polymorphism (SNP) rs992157 (2q35) and CRC was independently replicated (p=2.08 x 10(-4); OR, 1.14; 95% CI, 1.06-1.23), and it was genome-wide significant in combined analysis (p=1.50 x 10(-9); OR, 1.12; 95% CI, 1.08-1.16). Variants at 2q35, 6p21.2, 8q23.3, 8q24.21, 10q22.3, 10q24.2, 11q13.4, 11q23.1, 14q22.2, 15q13.3, 18q21.1, 20p12.3 and 20q13.33 were associated with CRC in the Finnish population (false discovery rate<0.1), but new risk loci were not found. These results replicate the effects of multiple loci on the risk of CRC and identify shared risk alleles between the Finnish population isolate and outbred populations.

A comprehensive structural, biochemical and biological profiling of the human NUDIX hydrolase family
- 2017

Ingår i: Nature Communications. - : Nature Publishing Group. - 2041-1723. ; 8:1

Tidskriftsartikel (refereegranskat)abstract
- The NUDIX enzymes are involved in cellular metabolism and homeostasis, as well as mRNA processing. Although highly conserved throughout all organisms, their biological roles and biochemical redundancies remain largely unclear. To address this, we globally resolve their individual properties and inter-relationships. We purify 18 of the human NUDIX proteins and screen 52 substrates, providing a substrate redundancy map. Using crystal structures, we generate sequence alignment analyses revealing four major structural classes. To a certain extent, their substrate preference redundancies correlate with structural classes, thus linking structure and activity relationships. To elucidate interdependence among the NUDIX hydrolases, we pairwise deplete them generating an epistatic interaction map, evaluate cell cycle perturbations upon knockdown in normal and cancer cells, and analyse their protein and mRNA expression in normal and cancer tissues. Using a novel FUSION algorithm, we integrate all data creating a comprehensive NUDIX enzyme profile map, which will prove fundamental to understanding their biological functionality.

Treatment selection in metastatic renal cell carcinoma : Towards an individualised approach
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Renal cell carcinoma (RCC), a common malignancy worldwide, affects 1200 new patients yearly in Sweden. Metastatic RCC (mRCC) develops in one in three and is commonly incurable. Clear cell histology dominates followed by papillary histology. The mainstay of mRCC treatment is targeted agents (TA) against aberrantly signalling pro-angiogenic tyrosine kinase receptors, and recently also immune checkpoint inhibitors. Local metastatic therapy with stereotactic radiotherapy (SRT) or surgical metastasectomy may be considered for oligometastatic disease.The aims of this thesis were (1) to identify clinically relevant factors useful for prognostication in real-world patients with mRCC treated in the TA era, (2) to deepen the understanding of papillary mRCC, and (3) to evaluate local metastatic therapy in mRCC. The papers of this thesis were based on retrospective data from regional databases or patient records from 2005 and onwards to reflect the contemporary therapeutic landscape.Paper I was a single-centre study analysing inflammatory blood and clinical parameters in relation to overall survival (OS) in mRCC (n=84). Median OS (mOS) was 20 months. Hypoalbuminemia was a negative prognostic factor (HR 2.7), independently of patient performance status (PS) or Memorial Sloan Kettering Cancer Center risk criteria.Paper II included solely patients with papillary mRCC (n=86) treated at three centres. mOS was 11 months. Age ≥60 years (HR 2.2), ≥3 metastatic sites (HR 2.7), and Eastern Cooperative Oncology Group (ECOG) PS ≥2 vs 1 (HR 3.0) were independently associated with worse OS.Paper III included mRCC patients treated with local metastatic therapy (n=117). Survival was similar irrespective of SRT or surgical metastasectomy with a mOS of 51 months. Treatment with TA in close proximity to local therapy was well tolerated. ECOG PS 1 vs 0 (HR 2.9), intracranial treatment (HR 1.8), and watchful waiting ≥18 months prior to treatment (HR 0.3) were independently prognostic. Paper IV was a follow-up of patients with ccRCC brain metastases treated with single fraction gamma knife radiosurgery (sf-GKRS) at three European centres (n=43). 1- and 3-year local control rates were 97% and 90%, and mOS was 16 months. Hypoalbuminemia (HR=5.3), corticosteroids prior to sf-GKRS (HR=5.8), and Karnofsky PS <80% (HR=9.1) were independently associated with worse OS, whereas previously described prognostic scores were not. Adverse radiation effects (ARE) were uncommon and associated with large target volumes and pre-treatment oedema.In conclusion, this thesis identifies several factors potentially useful for prognostication in mRCC, and indicates the usefulness of local metastatic therapy, in particular SRT, in selected patients. The results should be validated prospectively.

Proteogenomic analysis of acute myeloid leukemia associates relapsed disease with reprogrammed energy metabolism both in adults and children

Tidskriftsartikel (refereegranskat)abstract
- Despite improvement of current treatment strategies and novel targeted drugs, relapse and treatment resistance largely determine the outcome for acute myeloid leukemia (AML) patients. To identify the underlying molecular characteristics, numerous studies have been aimed to decipher the genomic- and transcriptomic landscape of AML. Nevertheless, further molecular changes allowing malignant cells to escape treatment remain to be elucidated. Mass spectrometry is a powerful tool enabling detailed insights into proteomic changes that could explain AML relapse and resistance. Here, we investigated AML samples from 47 adult and 22 pediatric patients at serial time-points during disease progression using mass spectrometry-based in-depth proteomics. We show that the proteomic profile at relapse is enriched for mitochondrial ribosomal proteins and subunits of the respiratory chain complex, indicative of reprogrammed energy metabolism from diagnosis to relapse. Further, higher levels of granzymes and lower levels of the anti-inflammatory protein CR1/CD35 suggest an inflammatory signature promoting disease progression. Finally, through a proteogenomic approach, we detected novel peptides, which present a promising repertoire in the search for biomarkers and tumor-specific druggable targets. Altogether, this study highlights the importance of proteomic studies in holistic approaches to improve treatment and survival of AML patients.
