  • Discovery of drug–omics associations in type 2 diabetes with generative deep-learning models
  • 2023

    • The application of multiple omics technologies in biomedical cohorts has the potential to reveal patient-level disease characteristics and individualized response to treatment. However, the scale and heterogeneous nature of multi-modal data makes integration and inference a non-trivial task. We developed a deep-learning-based framework, multi-omics variational autoencoders (MOVE), to integrate such data and applied it to a cohort of 789 people with newly diagnosed type 2 diabetes with deep multi-omics phenotyping from the DIRECT consortium. Using in silico perturbations, we identified drug–omics associations across the multi-modal datasets for the 20 most prevalent drugs given to people with type 2 diabetes with substantially higher sensitivity than univariate statistical tests. From these, we among others, identified novel associations between metformin and the gut microbiota as well as opposite molecular responses for the two statins, simvastatin and atorvastatin. We used the associations to quantify drug–drug similarities, assess the degree of polypharmacy and conclude that drug effects are distributed across the multi-omics modalities.

  • Thermodynamic stability and denaturation kinetics of a benign natural transthyretin mutant identified in a Danish kindred
  • 2011
  • In: AMYLOID-JOURNAL OF PROTEIN FOLDING DISORDERS. - : Informa Healthcare. - 1350-6129. ; 18:2, s. 35-46
  • Journal article (peer-reviewed)abstract
    • The disease phenotype of transthyretin (TTR) is dramatically influenced by single point mutations in the TTR gene. Herein, we report on a novel mutation D99N (Asp99Asn) in TTR found in a Danish kindred. None of the family members carrying this mutation have so far shown any clinical signs of amyloidosis. One carrier found compound heterozygous for TTR D99N and L111M (Leu111Met) associated with cardiac amyloid is asymptomatic (42 years). Disease severity can often be linked to both the kinetics of fibril formation and the degree of destabilisation of the native state. In this study, we show that the thermodynamic stability and rate of tetramer dissociation of the variant TTR D99N is unchanged or slightly more stable than wild type (WT) TTR. Furthermore, the in vitro fibrillation kinetics of the variant reveals an unchanged or slightly suppressed tendency to form fibrils compared to WT. Thus, the in vitro experiments support the lack of clinical symptoms observed so far for the TTR D99N carriers. In line with this, studies on kinetic stability and fibrillation kinetics reveal indistinguishable stability of TTR heterotetramers D99N/L111M compared to the heterotetramers WT/L111M. In conclusion, TTR D99N is predicted to be a non-pathogenic benign mutation with WT properties.andlt;/.
