PLK1 inhibitors as potential new treatment for adrenocortical carcinoma

Smith Gabrielle , Liang Raimunde , Chortis Vasileios , Lippert Juliane , Hantel Constanze , Altieri Barbara , Fassnacht Martin , Foster Paul , Ronchi Cristina

Background: Adrenocortical carcinoma (ACC) is a rare aggressive cancer with limited treatment options for advanced stages. By targeted RNA expression screening, we identified polo-like kinase 1 (PLK1) as one of most overexpressed genes, thus representing a potential drug target for ACC. PLK1 inhibitors are under evaluation in clinical trials for other solid cancers and seem to be more effective in TP53 mutated tumours. The aim of the study was to evaluate PLK1 protein levels i...

Adrenocortical carcinomas (ACC) are associated with heterogeneous prognosis and limited treatment options for advanced stages. Until now no efficient targeted therapies have been identified. This study aims to identify possible new molecular drug targets for a future personalized therapeutic approach. We isolated good quality RNA from 40 formalin-fixed paraffin-embedded tumor samples (33 from primary surgery, 5 from local recurrences and 2 from distant metastasis) of ACC patie...

Adrenocortical carcinoma (ACC) is an aggressive malignancy with limited treatment options. We identified polo-like kinase 1 (PLK1) as one of the most overexpressed genes and potential drug target in ACC. PLK1 inhibitors (PLK1i) are under evaluation in clinical trials for other malignancies, being more effective in TP53-mutated tumours. Here we test PLK1i efficacy in four ACC cell lines with different genetic background. Efficacy of three PLK1i (i.e. Volaserti...

Cyclin dependent kinase 4 as promising drug target in adrenocortical carcinoma

Liang Raimunde , Weigand Isabel , Sbiera Silviu , Kircher Stefan , Lippert Juliane , Altieri Barbara , Steinhauer Sonja , Hantel Constanze , Rost Simone , Rosenwald Andreas , Kroiss Matthias , Fassnacht Martin , Ronchi Cristina

Adrenocortical carcinomas (ACC) are associated with heterogeneous prognosis and limited treatment options for advanced stages. Until now no efficient targeted therapies have been identified. This study aims to identify possible new molecular drug targets for a future personalized therapeutic approach. RNA was isolated from 40 formalin-fixed paraffin-embedded tumor samples from ACC patients (26F&14M, median age 46 yrs) with known genetic background (Lippert et al. JCEM ...

Targeted molecular analysis in adrenocortical carcinomas: a way towards personalized medicine

Ronchi Cristina L , Lippert Juliane , Appenzeller Silke , Sbiera Silviu , Steinhauer Sonja , Liang Raimunde , Gehrig Andrea , Kroiss Matthias , Rost Simone , Rosenwald Andreas , Muller-Reible Clemens , Fassnacht Martin

Adrenocortical carcinoma (ACC) is a rare tumor with heterogeneous outcome and no available targeted therapy. The aim of the study is to identify prognostic molecular markers and novel potential drug targets.A total of 43 FFPE tumor samples were retrospectively investigated for somatic mutations and copy number variations (CNV) by next-generation sequencing (160 cancer-related genes, Qiagen). Gene expression was evaluated by quantitative RT-PCR in a subgr...

Targeted molecular analysis in adrenocortical carcinomas: a strategy towards improved personalized prognostication

Lippert Juliane , Appenzeller Silke , Liang Raimunde , Sbiera Silviu , Kircher Stefan , Altieri Barbara , Weigand Isabel , Riemens Renzo , Rosenwald Andreas , Kroiss Matthias , Rost Simone , Fassnacht Martin , Ronchi Cristina

Background: Adrenocortical carcinoma (ACC) has a heterogeneous prognosis and current medical therapies have limited efficacy in its advanced stages. Genome-wide multi-omics-studies identified molecular patterns associated with clinical outcome. Here, we aimed at identifying a molecular signature useful for both personalized prognostic stratification and druggable targets, using methods applicable in clinical routine.Methods: 117 tumor samples from 107 AC...

Targeted molecular analysis in adrenocortical carcinomas: a way towards improved personalized prognostication

Lippert Juliane , Appenzeller Silke , Liang Raimunde , Sbiera Silviu , Kircher Stefan , Altieri Barbara , Nanda Indrajit , Weigand Isabel , Gehrig Andrea , Steinhauer Sonja , Mueller Clemens , Kroiss Matthias , Rost Simone , Rosenwald Andreas , Fassnacht Martin , Ronchi Cristina

Adrenocortical carcinoma (ACC) has heterogeneous prognosis and no effective targeted therapies. Pan-genomic studies identified complex molecular patterns related to outcome. Our study aimed at identification of an ‘easy-to-apply’ molecular signature for better personalized prognostic stratification. A total of 107 ACC patients were enrolled. Clinical/histopathological parameters of prognostic relevance were evaluated. Targeted molecular analysis was performed on DNA ...
