Project description:In this study we want present a bank of metastatic colorectal cancer (mCRC) Patient Derived Organoids (PDOs) obtained from Patient Derived Xenografts (PDXs). These models are annotated with different omics to advance our understanding of CRC. We wanted to create a resource for the scientific community to assess the predictive reliability of these preclinical models. We performed comparative analyses between PDOs and matched PDXs to assess the similarities of these two platforms regarding molecular profiles and transcriptional classification. Moreover, we analyzed how these models respond to Cetuximab, a chimeric monoclonal antibody, normally given to patients after chemotherapy, that inhibits EGFR. After having assessed models’ reliability with Cetuximab, we aimed at identifying potential synergistic drugs to individuate new possible therapeutic prospects.
Project description:In this study, pediatric ALL patient-derived xenografts (PDXs) inherently resistant to glucocorticoids were cultured in vitro. The study aims to determine discrepancy in gene expressions between different xeno strains. The same xenograft was innoculated into 3 mice. Spleen-harvest xenograft samples were analyzed using microarray.
Project description:Transcriptome profiling analysis was performed in 22 human prostate cancer organoids, 6 patient-derived xenografts (PDXs) and 7 cell lines.

Project description:To identify the molecular signature associated with abiraterone acetate (AA) response and mechanisms underlying AA resistance in castration-resistant prostate cancer patient-derived xenografts (PDXs).
