Adrenocortical carcinomas (ACCs) overexpress insulin-like growth factor 2 (IGF2), that drives a proliferative autocrine loop by binding to IGF1R and IR, but IGF1R/IR-targeted therapies failed in ACC patients. The cytoskeleton actin-binding protein filamin A (FLNA) impairs IR signalling melanoma cells. Aims of this study were test FLNA involvement regulating responsiveness both IGF2 inhibitors A...
The emerging role of the molecular marker p27 in the differential diagnosis of adrenocortical tumors
Malignant adrenocortical tumors (ACTs) are rare and highly aggressive; conversely, benign tumors are common and frequently found incidentally (the so-called incidentalomas). Currently, the use of molecular markers in the diagnosis of ACTs is still controversial. The aim of this study was to analyze the molecular profile of different ACTs with the purpose of identifying markers useful for differ...
Aims: The rate of adrenal mass detection has increased due to the development imaging modalities. It is vital differentiate benign adenomas from other masses in order establish whether an active management strategy essential. Volumetric CT histogram analysis calculates percentage covered pixels negative attenuation region. goal this research was evaluate diagnostic utility volume for tumors con...
Cullin 4A (CUL4A) is an E3 ubiquitin ligase that directly affects DNA repair and cell cycle progression by targeting substrates including damage-specific DNA-binding protein 2 (DDB2), xeroderma pigmentosum complementation group C (XPC), chromatin licensing and DNA replication factor 1 (Cdt1), and p21. Recent work from our laboratory has shown that Cul4a-deficient mice have greatly reduced rates...
Adrenocortical carcinoma (ACC) is a rare, highly malignant tumor. The aim of the present study is to evaluate the prognostic relevance of a proliferation marker Ki67/MIB1 by immunohistochemistry in 17 cases who underwent resections of the primary tumors and diagnosed to have ACC at Tohoku University Hospital based on the criteria of Weiss during the period from 1976 to 2005. The follow-up perio...
Telomerase was found in cancers and immortalized cell lines, but only occasionally in normal tissues, thus suggesting that measurement of its hTERT subunit might help distinguishing benign from malignant tumors. Data on hTERT expression in adrenocortical tumors are scant and mostly confined to non-functioning tumors. Therefore, we investigated whether hTERT expression may predict malignancy in ...
adrenocortical tumors (acts) are extremely rare in infants. pediatric acts are therapeutic and diagnostic challenge because histological criteria for distinguishing benign from malignant tumors seen in adults are not always reliable in children .the aim of this report was to present clinical features, hormonal profile, and histopathological characteristics of an infant with adrenal tumors. a 10...
