BACKGROUND KIAA0101 is a proliferating cell nuclear antigen-associated factor that is overexpressed in some human malignancies. Adrenocortical neoplasm is one of the most common human neoplasms for which the molecular causes are poorly understood. Moreover, it is difficult to distinguish between localized benign and malignant adrenocortical tumors. For these reasons, we studied the expression, ...

BACKGROUND The molecular mechanisms involved in the genesis of the adrenocortical lesions seen in MEN1 syndrome (ACL-MEN1) remain poorly understood; loss of heterozygosity at 11q13 and somatic mutations of MEN1 are not usually found in these lesions. Thus, additional genes must be involved in MEN1 adrenocortical disorders. Overexpression of the glucose-dependent insulinotropic peptide receptor ...

The proliferative activity, the organization and the corticosterone expression of adrenocortical cells in an experimental adrenal regeneration process after the transplantation of neonatal adrenal glands to adult hosts was investigated. Three days after transplantation, the medullar and the innermost adrenocortical cells of the neonatal adrenal glands showed degenerative and necrotic changes du...

Adrenocortical carcinoma (ACC) is a rare malignancy with poor prognosis, and it can be classified as either a functional or nonfunctional tumor. Affected patients usually present with abdominal pain or with symptoms related to the mass effect or hormonal activity of the tumor. Several cases of spontaneously ruptured nonfunctional adrenocortical carcinoma have been reported, but no case of a spo...

The histopathologic features of 10 myxoid adrenocortical neoplasms were analyzed, and epidermal growth factor receptor (EGFR) expression, EGFR gene copy number, and EGFR gene mutations in the 10 tumors were detected by using immunohistochemical analysis, fluorescence in situ hybridization, and the Scorpion Amplification Refractory Mutation System (DxS, Manchester, England), respectively. Histol...

The thyroid disorders are found to be prevalent in Himalayan and sub Himalayan regions and the studies focusing on the association between thyroid function markers and lipid metabolism are sparse. The present study was aimed to study the impact of thyroid hyperfunction on lipoprotein metabolism and hepatic lipase activity. Two ninety subjects (255 females, 35 males) aged 2555 years with a clini...

Adrenocortical tumors are frequently found in the general population, and may be benign adrenocortical adenomas or malignant adrenocortical carcinomas. Unfortunately the clinical, biochemical and histopathological distinction between benign and malignant adrenocortical tumors may be difficult in the absence of widely invasive or metastatic disease, and hence attention has turned towards a searc...

Cyclic-AMP (cAMP)-dependent protein kinase (PKA) is the main effector of cAMP signaling in all tissues. Inactivating mutations of the PRKAR1A gene, coding for the type 1A regulatory subunit of PKA, are responsible for Carney complex and primary pigmented nodular adrenocortical disease (PPNAD). PRKAR1A inactivation and PKA dysregulation have been implicated in various types of adrenocortical pat...

Adrenocortical carcinoma (ACC) is a rare, but highly aggressive type of tumor with an incidence of one to two per million annually. Adrenocortical carcinosarcoma is an exceptional variant of ACC, which is characterized by the presence of histological regions of carcinoma and sarcoma. To date, to the best of our knowledge, there have only been 12 reported cases of adrenocortical carcinosarcoma. ...
