Increased concentrations of insulin-like growth factor-binding protein-2 (IGFBP-2) have been observed in human malignancies including adrenocortical carcinomas. To elucidate the functional consequences of IGFBP-2 overexpression, we have stably transfected the cDNA of murine IGFBP-2 in mouse adrenocortical tumor cells (Y-1). Long-term overexpression of IGFBP-2 was associated with significant mor...
BACKGROUND Identifying novel tumor biomarkers to develop more effective diagnostic and therapeutic strategies for patients with ACC is urgently needed. The aim of the study was to compare the proteomic profiles between adrenocortical carcinomas (ACC) and normal adrenocortical tissues in order to identify novel potential biomarkers for ACC. METHODS The protein samples from 12 ACC tissues and t...
Overexpression of insulin growth factor 2 (IGF2) is a hallmark of adrenocortical carcinomas and pheochromocytomas. Previous studies investigating the IGF2/H19 locus have mainly focused on a single molecular level such as genomic alterations or altered DNA methylation levels and the causal changes underlying IGF2 overexpression are still not fully established. In the current study, we analyzed 6...
OBJECTIVE Tumours in the adrenocortex are common human tumours. Malignancy is however, rare, the yearly incidence being 0.5-2 per million inhabitants, but associated with a very aggressive behaviour. Adrenocortical tumours are often associated with altered hormone production with a variety of clinical symptoms. The aggressiveness of carcinomas together with the high frequency of adenomas calls ...
In estrogen-induced, estrogen-dependent, mammary and adrenocorlical carcinomas, the specific activities of t lie tliymidine kinasc and thymidylate kinase decreased significantly within 2 to 4 days after removal of the source of estrogen of the host. After 7 days, these changes were even more marked in the adrenal tumors. Similar changes were not observed in the activity of these enzymes in auto...
Adrenal tumors are common, with an estimated incidence of 7.3% in autopsy cases, while adrenocortical carcinomas (ACCs) are rare, with an estimated prevalence of 4-12 per million population. Because the prognoses for adrenocortical adenomas (ACAs) and ACCs are vastly different, it is important to be able to accurately differentiate the two tumor types. Advancement in the understanding of the pa...
