Predicting the impact of cancer somatic mutations on protein-protein interactions
Özet
Cancer is a complex disease with one of the highest mortality rates. An existence challenge in cancer research is to identify the cancer driver mutation that causes cancer
progression. Many biological processes are governed by protein-protein interactions. As
such understanding which somatic mutations lead to a disruption in these interactions is
critical for cancer research. A drawback common to most of the existing models is the
assumption that a mutation in a protein causes the same effect on all of its interactions.
Predicting how each interaction is affected by a mutation of interest is crucial for
understanding disease development. In this thesis, we propose a model named Predator.
Predator provides better prediction accuracy than the alternatives. The developed model
is applied on the cancer data in the TCGA. Proposed approach is a novel study to analyze
the effects of cancer mutations from TCGA on protein-protein interactions by classifying
the impacts into disruptive/nondisruptive classes and having analyses specific to cancer.
Such analyses may be beneficial for providing new insights regarding the mutations that
are predicted to have a disruptive effect on cancer groups.

A computational approach for prioritization of patient-specific cancer drivers
Taleb Bahmed, Ahmed Amine (Antalya Bilim Üniversitesi Lisansüstü Eğitim Enstitüsü, 2020)major challenge in cancer genomics is to distinguish the driver mutations that are causally linked to cancer from passenger mutations that are neutral and do not contribute to cancer development. The identification of these ...
