All-trans-retinoic acid (RA) plays a crucial role in survival and differentiation of neurons. For elucidating signaling mechanisms involved in RA-induced neuronal differentiation, we have selected SH-SY5Y cells, which are an established in vitro cell model for studying RA signaling. Here we report that RA-induced neuronal differentiation of SH-SY5Y cells is(More)
Renal transplantation (RTx) recipients have a high incidence of cancer, including transitional cell carcinoma (TCC). Posttransplantation urologic malignancies still present a challenge for transplant surgeons. Using the Dialysis and Transplant Registry of Taichung Veterans General Hospital, a total of 55 cancers were diagnosed in 52 RTx recipients between(More)
Rho GTPases such as RhoA, Rac1 and Cdc42 are crucial players in the regulation of signal transduction pathways required for neuronal differentiation. Using an in vitro cell culture model of neuroblastoma SH-SY5Y cells, we demonstrated previously that RhoA is an in vivo substrate of tissue transglutaminase (TGase) and retinoic acid (RA) promoted activation(More)
BACKGROUND To find a predictor for extracapsular tumor extension at radical retropubic prostatectomy (RRP) in Taiwanese patients with stage T1c prostate cancer (PC), preoperative transrectal sonoguiding prostate biopsy outcomes and clinicopathological data obtained from these patients were reviewed. METHODS Fifty-five consecutive men who underwent radical(More)
Endopolyploidy is frequently observed during development in plant species. Patterns of endopolyploidy are diverse in the various organs of different plant species. However, little is known about the role of endopolyploidization and its significance in orchids. This study was undertaken to determine the extent of endopolyploidy in different tissues of the(More)
Intra-abdominal retained surgical sponge is an uncommon surgical error. Herein, we report a 92-year-old woman who was brought to the emergency room for acute urinary retention. She had a history of vaginal hysterectomy for uterine prolapse 18 years previously, performed at our hospital. Retained surgical sponge in the pelvic cavity was suspected by(More)
BACKGROUND The prognosis and proper treatment of stage T1a prostate cancer remain unsettled. The aim of the study was to identify retrospectively some predictors of disease progression in stage T1a prostate cancer. METHODS We reported on 52 patients with stage T1a prostate cancer diagnosed between 1983 and 1996 at Taichung Veterans General Hospital. The(More)
The two cancers after renal transplantation (RTx) are transitional cell carcinoma (TCC) and hepatoma reported in Taiwan most frequently, versus lymphproliferative diseases and skin cancers in the Western literature. Herein, we present a 49-year-old man with spinal cord injury and end-stage renal disease who developed multifocal TCC in the urologic tract and(More)
OBJECTIVES To evaluate prospectively the prognostic power of urinary nuclear matrix protein-22 (NMP-22) for bladder cancer in Taiwanese screening and surveillance settings. METHODS Single voided urine samples were obtained from 68 healthy individuals, 303 patients with benign urothelial diseases, and 28 patients with urogenital tumors. The NMP-22 levels(More)
Eosinophil cationic protein (ECP) is a major component of eosinophil granule protein that is used as a clinical bio-marker for asthma and allergic inflammatory diseases. Previously, it has been reported that the signal peptide of human ECP (ECPsp) inhibits the cell growth of Escherichia coli (E. coli) and Pichia pastoris (P. pastoris), but not mammalian(More)
