Role of the Wnt signaling pathway in keratoacanthoma

Autor: Ole Petter F. Clausen, Sarita Joshi, Paula M. De Angelis, Solveig Norheim Andersen, Manuela Zucknick, Aasa R. Schjølberg

Publikováno v: Cancer Rep (Hoboken)

Background Keratoacanthoma (KA) has a unique life cycle of rapid growth and spontaneous regression that shows similarities to the hair follicle cycle, which involves an active Wnt signaling during physiological regeneration. We analyzed the expressio

Tp53/p53 status in keratoacanthomas

Autor: Per Olaf Ekstrøm, Manuela Zucknick, Solveig Norheim Andersen, Sarita Joshi, Ole Petter F. Clausen, Paula M. De Angelis, Aasa R. Schjølberg

Publikováno v: Journal of Cutaneous Pathology. 43:571-578

Background Keratoacanthoma (KA) is a common keratinocytic skin neoplasm that typically develops rapidly and undergoes complete spontaneous regression. As the pro-apoptotic p53 protein may be involved in the lifecycle of KA, we studied the p53 status

Aggressive melanoma in an infant with congenital melanocytic nevus syndrome and multiple, NRAS and BRAF mutation-negative nodules

Autor: Arild Rønnestad, Svetlana Tafjord, Kim Alexander Tønseth, Daniel de la Rosa Carrillo, Lil-Sofie Ording Müller, Ole Petter F. Clausen, Veronica A. Kinsler, Harald Vindenes, Bjørn Kvamme, Geir Ringstad

We report the case of a newborn boy with multinodular NRAS and BRAF mutation-negative congenital melanocytic nevi and cerebral lesions compatible with congenital intraparenchymal melanosis. Histopathology from skin lesions showed atypical nodular mel

Publikováno v: Hepatology (Baltimore, Md.)

Early detection of the highly aggressive malignancy cholangiocarcinoma (CCA) remains a challenge but has the potential to render the tumor curable by surgical removal. This study evaluates a biomarker panel for the diagnosis of CCA by DNA methylation

Expression of the Ly6/uPAR-Domain Proteins C4.4A and Haldisin in Non-Invasive and Invasive Skin Lesions

Autor: Michael Ploug, Ole Didrik Laerum, Ole Petter F. Clausen, Mette C. Kriegbaum

Publikováno v: Journal of Histochemistry & Cytochemistry. 63:142-154

C4.4A and Haldisin belong to the Ly6/uPAR/α-neurotoxin protein domain family. They exhibit highly regulated expression profiles in normal epidermis, where they are confined to early (C4.4A) and late (Haldisin) squamous differentiation. We have now e

TP53/p53 alterations and Aurora A expression in progressor and non-progressor colectomies from patients with longstanding ulcerative colitis

Autor: Espen Burum-Auensen, Ole Petter F. Clausen, Aasa R. Schjølberg, Mariann Friis-Ottessen, Solveig Norheim Andersen, Paula M. De Angelis, Per Olaf Ekstrøm

Publikováno v: International Journal of Molecular Medicine

Aneuploidy is a common feature in the colonic mucosa of patients suffering from the inflammatory bowel disease ulcerative colitis (UC) and often precedes the development of dysplasia and cancer. Aneuploidy is assumed to be caused by missegregation of

Publikováno v: International Journal of Molecular Medicine

Longstanding ulcerative colitis (UC) is a disease of chronic inflammation of the colon. It is associated with the development of colorectal cancer through a multistep process including increasing degrees of dysplasia and DNA-ploidy changes. However,

Patients with small duct primary sclerosing cholangitis have a favourable long term prognosis

Autor: Kenneth A. Fleming, Ole Petter F. Clausen, Erik Schrumpf, Roger W. Chapman, Einar Björnsson, Kirsten Muri Boberg, O Fausa, S N Cullen

Background: Patients with cholestatic liver function tests and histological features of primary sclerosing cholangitis (PSC) but a normal cholangiogram are considered to have small duct PSC. The natural history of this condition is unknown. Methods:
