Resumo:
Unilateral cortisol producing adenoma (CPA) is the most common cause of ACTH-independent Cushing’s syndrome and is surgically curable. On the other hand, adrenocortical carcinomas (ACCs) are rare and aggressive tumours. Although the overall survival of the patients with ACC is very poor, the outcome can be heterogeneous and vary significantly between the patients. This thesis comprises studies showing genetic and genomic events occurring in CPAs and ACCs, their functional impact and clinical correlations. The Wnt/β-catenin and cAMP/PKA signalling pathways are crucial in adrenal homeostasis and frequent mutations in members of these pathways (CTNNB1, GNAS, and PRKACA) are found in CPAs. Mutational analysis revealed that ~60% of the CPAs harboured mutations in either of these genes. Transcriptome signature exhibited increased expression of genes involved in steroidogenesis in PRKACA/GNAS mutated (Cluster1) tumours in comparison to CTNNB1 mutated /wildtype (Cluster2) tumours. In addition we have also observed that gain of chromosome arm 9q was the most frequent arm level copy number variation (CNV) occurring in CPAs and were exclusively present in Cluster2 tumours. We also discovered novel PRKACA mutations occurring in ACCs, causing activation of cAMP/signalling pathway.    Comprehensive analysis of Wnt/β-catenin signalling pathway in ACCs revealed novel interstitial deletions occurring in CTNNB1 leading to deletion of the N-terminus of β-catenin. This is a novel and yet another frequent event leading to activated Wnt/β-catenin signalling and downstream targets in ACCs. Both, mutations occurring in CTNNB1 and nuclear expression of its protein were associated with poor overall survival. Through multiregional sampling approach we discovered intra-tumour heterogeneity in ACC tumours. Although all the multiregions within a tumour showed presence of shared basal CNVs, they encompassed private CNVs, different ploidy levels and private mutations in known driver genes. We found intra-tumour heterogeneity in CTNNB1, PRKACA, TERT promoter and TP53 mutations as well as ZNRF3 and CDKN2A/2B homozygous deletions.

Understanding signalling pathways that control pancreatic endocrine tumour (PET) development and proliferation may reveal novel targets for therapeutic intervention. The pathogenesis for sporadic and hereditary PETs, apart from mutations of the MEN1 and VHL tumour suppressor genes, is still elusive. The protein product of the MEN1 gene, menin, regulates many genes. The aim of this thesis was to identify genes involved in pancreatic endocrine tumourigenesis, with special reference to Notch signalling.

Messenger RNA and protein expression of NOTCH1, HES1, HEY1, ASCL1, NEUROG3, NEUROD1, DLK1, POU3F4, PDX1, RPL10, DKK1 and TPH1 were studied in human PETs, sporadic and MEN 1, as well as in tumours from heterozygous Men1 mice. For comparison, normal and MEN1 non-tumourous human and mouse pancreatic specimens were used. Nuclear expression of HES1 was consistently absent in PETs. In mouse tumours this coincided with loss of menin expression, and there was a correlation between Men1 expression and several Notch signalling factors. A new phenotype consisting of numerous menin-expressing endocrine cell clusters, smaller than islets, was found in Men1 mice. Expression of NEUROG3 and NEUROD1 was predominantly localised to the cytoplasm in PETs and islets from MEN 1 patients and Men1 mice, whereas expression was solely nuclear in wt mice. Differences in expression levels of Pou3f4, Rpl10 and Dlk1 between islets of Men1 and wt mice were observed.

In addition, combined RNA interference and microarray expression analysis in the pancreatic endocrine cell line BON1 identified 158 target genes of ASCL1. For two of these, DKK1 (a negative regulator of the WNT/β-catenin signalling pathway) and TPH1, immunohistochemistry was performed on PETs. In concordance with the microarray finding, DKK1 expression showed an inverse relation to ASCL1 expression.

Altered subcellular localisation of HES1, NEUROD1 and NEUROG3 and down-regulation of DKK1 may contribute to tumourigenesis.

Resumo:
Recent studies have demonstrated that cysteine cathepsin S, predominantly from tumour- associated macrophages, promotes tumour development and progression. Conversely, previous work examining human colorectal and brain biopsies have shown that the tumour cells themselves are a major source of CatS. In order to clarify the contribution of stromal- derived versus tumour cell-derived CatS in colorectal tumourigenesis, investigations were carried out using the syngeneic MC38 coloadenocarcinoma cell line, which was found to expressed and produced CatS. Loss-of-function CatS experiments performed on the MC38 cells demonstrated a reduction in invasion, lower activity level and reduced proteolysis, signifying a role for CatS in various aspects of tumourigenesis. Investigations in vivo using CatS null mice revealed a role for both tumour cell and stromal-derived CatS in MC38 tumour development and highlighted that CatS derived from either sources partially compensated for each other, and that depletion from both sources was required for the most significant retardation of tumour growth, This noted anti-tumour effect was characterised by a reduction in tumour cell proliferation and increased apoptosis, which may be attributable, at least in part, to the significant diminution in tumour neo-angiogenesis. Mean vessel number and vessel area was significantly reduced in tumours which lacked both sources of CatS, were the vessels presented with increased leakiness; suggestive of more dysfunctional tumour vessel architecture, The observation of increased lung and liver metastases in the CatS null mice was unexpected, however, this may be due to the expression of tumour cell derived CatS, thereby promoting rnetastases. This may be a result of decreased immuno-protective and anti-tumour roles due to the loss of CatS. Taken together, these findings clearly highlight a functional role for CatS in several hallmarks of tumourigenesis, particularly angiogenesis. The data also demonstrates CatS as a valid anti-angiogenic target in the treatment of cancer, at least in solid tumours.

Neuroblastoma, a malignant neoplasm of the sympathetic nervous system, is the most common extracranial solid tumour in childhood. Since its first description in the nineteenth century, its highly heterogeneous clinical presentation has challenged clinicians and fascinated basic researchers. Neuroblastoma serves as a paradigm for the prognostic utility of biological and clinical data and the potential to tailor therapy for patient cohorts at low, intermediate, and high risk for recurrence. This chapter presents an overview of the key genetic, molecular, histological, and clinical features of neuroblastoma, as well as current risk-stratification strategies and therapeutic approaches. It also highlights how our understanding of tumour pathogenesis, coupled with molecular analyses, has illuminated critical signal transduction pathways and key molecules involved in neuroblastoma tumourigenesis, pointing to novel therapeutic targets for clinical development. Future treatment avenues for relapsed neuroblastoma are discussed, including new drugs targeting ALK, MYC/MYCN, histone deacetylases, or MDM2/TP53.
