  1. 1. Selective induction of apoptosis in tumors by small molecules reactivating p53

    Author : Natalia Issaeva; Karolinska Institutet; Karolinska Institutet; []
    Keywords : p53; HDM2; reactivation; apoptosis; tumors; small molecule.;

    Abstract : Lesions in the p53 pathway that inactivate p53 tumor suppression function occur with extremely high frequency in cancer, targeting almost all tumors regardless of patient age or tumor type. This study is aimed at developing approaches for the selective elimination of tumors carrying defects in the p53 pathway, namely protection of p53 from degradation by its own destructor HDM2 in wild type p53-carrying tumors and refolding of p53 by small molecules in mutant p53-containing tumors.

  2. 2. Identification and validation of therapeutic targets in sarcoma models

    Author : Wessen Maruwge; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In spite of the low incidence of sarcomas, they are highly aggressive tumors, with high metastatic potential, and resistance to both chemotherapy and radiotherapy, leaving surgery as the only treatment option. There is evidently an urgent need in identifying molecular targets and oncogenic pathways in sarcomas that can be used for the development and evaluation of drugs directed against these tumors.

  3. 3. Molecular mechanisms underlying the oncogenic function of SS18 and SSX

    Author : Pádraig D'Arcy; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The SS18 and SSX genes were initially identified based on their reoccurrence as fusion partners in synovial sarcoma. As a result of the specific chromosomal translocation t(X:18), the SS18 gene from chromosome 18 becomes fused with members of the SSX gene family on the X chromosome resulting in the generation of a novel chimeric fusion gene SS18-SSX.

  4. 4. Modulation of p53's transcriptional function by small molecules

    Author : Fedor Nikulenkov; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : p53 tumour suppressor is a transcriptional factor which induces apoptosis or growth arrest in response to stress thus eliminating damaged cells. p53 function is frequently abrogated in tumours either via inactivation mutations in the TP53 gene or by elevated activity of p53 negative regulators HDM2 and HDMX.

  5. 5. Identification of EBNA binding cellular proteins, using yeast two-hybrid system

    Author : Elena Kashuba; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Epstein-Barr virus (EBV) is a common herpesvirus that establishes life-long persistence in the human host through the elaborate regulation of different latency types. Latent EBV infection of resting B cells converts them into transformed cells that can develop into tumors in immune-compromised hosts. READ MORE
