MENX is a recessive multiple endocrine neoplasia-like syndrome in the rat. The tumor spectrum in MENX overlaps those of human multiple endocrine neoplasia (MEN) types 1 and 2. We mapped the MenX locus to the distal part of rat chromosome 4, excluding the homologs of the genes responsible for the MEN syndromes (RET and MEN1) and syndromes with an endocrine(More)
PURPOSE Aurora kinase A (AURKA/STK15/BTAK) encodes a serine/threonine kinase associated with chromosomal distribution and its up-regulation induces chromosomal instability, thereby leading to aneuploidy and cell transformation in several types of cancer. In this study, we investigated the role of AURKA in head and neck squamous cell carcinoma (HNSCC). (More)
Confocal laser scanning microscopy (CLSM) is an extensive but reliable tool for assessing the hybridisation signals in fluorescence in situ hybridisation (FISH). Most CLSMs are equipped with an argon-laser and a helium/neon-laser illumination system with excitation wavelengths of 488, 543 and 633 nm. A protocol for an optimal nuclear counterstaining in(More)
Primary extramedullary plasmacytoma is an indolent neoplasm that infrequently converts to multiple myeloma. Since cytogenetic data on extramedullary plasmacytoma are lacking, we studied 38 cases of this type of neoplasm by fluorescence in situ hybridization. Fourteen cases (37%) contained IGH breaks, including six with a t(4;14) translocation. No(More)
Histopathological examination of a bone marrow (BM) trephine biopsy is an integral part of the diagnostic work-up of patients with haematological disorders and other diseases which may afflict hematopoiesis. Until recently, the dramatic increase in modern immunological and molecular techniques which have been added to the diagnostic repertoire of clinical(More)
BACKGROUND Mantle cell lymphoma is a clinically heterogeneous disease characterized by overexpression of cyclin D1 protein. Blastoid morphology, high proliferation, and secondary genetic aberrations are markers of aggressive behavior. Expression profiling of mantle cell lymphoma revealed that predominance of the 3'UTR-deficient, short cyclin D1 mRNA isoform(More)
Pheochromocytomas are neoplasias of neural crest origin that arise from the chromaffin cells of the adrenal medulla. Pheochromocytomas arise with complete penetrance in rats homozygous for a germ-line frameshift mutation of Cdkn1b, encoding the cell cycle inhibitor p27KIP1 (MENX syndrome). We performed a genome-wide scan for allelic imbalance comparing 20(More)
CONCLUSIONS Numerical and structural centrosome abnormalities play a critical role in the tumor progression of in head and neck squamous cell carcinoma (HNSCC) and may provide useful information as a prognostic factor for these patients. OBJECTIVES Centrosome alterations are often linked with aneuploidy, cell transformation, and tumor progress. We(More)
spalt (sal) of Drosophila melanogaster is an important developmental regulator gene and encodes a zinc finger protein of unusual but characteristic structure. Two human sal-like genes have been isolated so far, SALL1 on chromosome 16q12.1 and SALL2 on chromosome 14q11.1-q12.1. Truncating mutations of SALL1 have been shown to cause Townes-Brocks syndrome and(More)
