Co-activation of super-enhancer-driven CCAT1 by TP63 and SOX2 promotes squamous cancer progression.

Squamous cell carcinomas (SCCs) are aggressive malignancies. Previous report demonstrated that master transcription factors (TFs) TP63 and SOX2 exhibited overlapping genomic occupancy in SCCs. However, functional consequence of their frequent co-localization at super-enhancers remains incompletely understood.

Distinct subcellular localization of E-cadherin between epithelioid angiomyolipoma and triphasic angiomyolipoma: A preliminary case-control study.

Epithelioid angiomyolipoma (EAML) is a rare variant of angiomyolipoma (AML). Previous studies have demonstrated that epithelial (E-)cadherin is expressed in two subtypes of AML, EAML and triphasic AML; however, the expression pattern of E-cadherin remains unclear. In the present study, a preliminary case-control study was conducted to determine the expression pattern of E-cadherin between EAML and triphasic AML, the control, focusing on the subcellular localization and expression category of E-cadherin.

A suggestion for pathological grossing and reporting based on prognostic indicators of malignancies from a pooled analysis of renal epithelioid angiomyolipoma.

Purpose: Epithelioid angiomyolipoma (EAML) is a rare entity of the kidney. The guideline for grossing and reporting of renal EAML has not been established for Chinese patients. We planned this study to provide some preliminary indicators for draft guidelines of pathological diagnosis among Chinese people.

[Detection of urothelial carcinoma of the urinary bladder by multicolor fluorescence in situ hybridization].

Background & Objective: Urothelial carcinoma of the urinary bladder is a common malignant neoplasm of the genitourinary system. This study was to analyze chromosome aberrations in urothelial carcinoma of the urinary bladder in Chinese, and evaluate the possibility and validity of multicolor fluorescence in situ hybridization (M-FISH) in detecting urothelial carcinoma of the urinary bladder.

Methods: The probes of chromosome 3, 7, 17 centromeres and 9p21 region were labeled by random primer method.

Detection of chromosomal alterations in bladder transitional cell carcinomas from Northern China by comparative genomic hybridization.

To identify chromosome alterations in Chinese bladder cancer, forty-six transitional cell carcinomas of the bladder were analyzed by comparative genomic hybridization. Frequent gains of DNA copy number were observed on 1p (13/46), 1q (13/46), 5p (8/46), 6p (9/46), 7p (7/46), 8q (12/46), 11q (8/46), 17q (11/46), 19q (7/46), 20q (8/46) and Yq (8/46), with minimal overlapping regions at 1p32-pter (10/46), 1q21-q24 (12/46), 5p (8/46), 6p22-p23 (7/46), 7p11.2-p14 (7/46), 8q22-q24 (12/46), 11q13-q14 (8/46), 17q22-qter (11/46), 19q11-13.
