BACKGROUND
Recessively transmitted polycystic kidney disease (PKD) in many murine models is characterized by the initial formation of proximal tubular cysts (stage 1), followed by growth and enlargement of renal collecting tubule (CT) cysts (stage 2). Previous studies have reported that stage 1 cyst
Two cases were encountered in which tyrosine crystals were identified by fine-needle aspiration biopsy in nonneoplastic, retention cysts of the parotid. Tyrosine crystals occasionally have been described in parotid neoplasms, but have not been reported in benign retention cysts. To study the
A case of multiple oncocytic cysts with intraluminal tyrosine-rich crystalloids involving the parotid gland is described. The microscopic and ultrastructural findings are presented.
A case of ovarian carcinoid tumor of the trabecular type is presented. The small carcinoid tumor was found incidentally in a resected dermoid cyst. Histologically, the tumor was surrounded by a smooth muscle layer with focal stromal invasion. Non-carcinoid papillary mucosa and a few small glands,
This study aimed to determine the expression of angiopoietin-1 (Ang-1), angiopoietin-2 (Ang-2), and endothelial tyrosine kinase receptor (Tie-2) in central nervous system (CNS) hemangioblastomas (HBs) and explore the correlation with peritumoral cyst formation.

Loss of miR-122 causes chronic steatohepatitis and spontaneous hepatocellular carcinoma. However, the consequence of miR-122 deficiency on genotoxic stress-induced liver pathogenesis is poorly understood. Here, we investigated the impact of miR-122 depletion on liver pathobiology by treating
Crizotinib is the first clinically available tyrosine kinase inhibitor that targets anaplastic lymphoma kinase (ALK) and is associated with the development of complex renal cysts. We now describe a 39-year-old woman who developed infected complex renal cysts during crizotinib treatment. After 10
Transcriptional coactivator with PDZ-binding motif (TAZ) physically interacts with a variety of transcription factors and modulates their activities involved in cell proliferation and mesenchymal stem cell differentiation. TAZ is highly expressed in the kidney, and a deficiency of this protein
Crizotinib is a tyrosine kinase inhibitor that has been found to be effective in the treatment of anaplastic lymphoma kinase (ALK) positive non-small cell lung cancer. This targeted cancer therapy agent has been shown to have superior efficacy over standard chemotherapy in this small subset of lung
The high rate of failure of new agents in oncology clinical trials indicates a weak understanding of the complexity of human cancer. Recent understanding of the mechanisms underlying castration resistance in prostate cancer led to the development of new agents targeting the androgen receptor
Background: Von Hippel-Lindau (VHL) disease is an autosomal-dominant hereditary cancer syndrome. Currently, studies on tyrosine kinase inhibitor (TKI) therapy for VHL disease are scarce. In this study, we retrospectively evaluated the efficacy and safety of four TKIs in patients with VHL
Protein tyrosine phosphorylation is a dynamic reversible process in which the level of phosphorylation, at any time, is the result of phosphatase and/or kinase activity. This balance is critical for control of growth and differentiation. The role of tyrosine phosphatases during nephrogenesis and in
Polycystic kidney disease is characterized by abnormal morphological development. Mechanisms that regulate cyst development may involve multiple signaling pathways. Cyst formation by Madin-Darby canine kidney (MDCK) cells in three-dimensional culture is assumed to be cyclic AMP-dependent and due to
The respiratory (tracheal) system of the Drosophila melanogaster larva is an intricate branched network of air-filled tubes. Its developmental logic is similar in some ways to that of the vertebrate vascular system. We previously described a unique embryonic tracheal tubulogenesis phenotype caused
