The production of reactive oxygen species (ROS) exerts an additional tier of control over tyrosine phosphorylation-dependent signal transduction by transiently inhibiting the catalytic activity of specific protein tyrosine phosphatases (PTPs). Hence, the ability to detect reversible oxidation of
A woman aged 56 years developed 2 synchronous tumours: one, 1.2 cm in diameter at the head of the pancreas; and the other, 4.0 cm in diameter, at the left side of her horseshoe kidney. Preoperative differential diagnosis of these hypovascular lesions included pancreatic ductal carcinoma (PDC) with
Perivascular epithelioid cells (PEC) in angiomyolipoma (AML) were recently proposed to be its most common progenitor cells. Histologically, triphasic components were present in various proportions, but were overwhelmingly myogenic in epithelioid variants of AML. Despite histological discrimination,
OBJECTIVE
The histological distinction between gastrointestinal smooth muscle neoplasms (SMNs) and their differential diagnoses, especially gastrointestinal stromal tumours (GISTs), has important clinical management implications. This study aimed to investigate preliminary data suggesting that loss
Tuberous sclerosis complex (TSC) is a relatively rare autosomal dominant disease which involves multiple organs, including the brain, kidney, lung, skin and heart. Renal angiomyolipomas (RAML) are the main causes of mortality in patients with TSC. The preferred treatment for RAML is the use of mTOR
