High NRBP1 expression promotes proliferation and correlates with poor prognosis in bladder cancer

Nuclear receptor binding protein 1 (NRBP1) is an evolutionarily highly conserved adaptor protein with multiple domains. Recently, its role in cancers has received increasing attention. To investigate whether NRBP1 is involved in the development of bladder cancer, we used tissue microarray and analyzed the association between the expression levels of NRBP1 and clinico-pathological features of 56 patients diagnosed with bladder cancer. Subsequently, NRBP1 was silenced using siRNA in bladder cancer cell lines T24 and 5637, and cell phenotype such as proliferation and apoptosis were observed. Further, in vivo tumor formation assay was performed. The expression of apoptosis markers was detected by Western blot. A significant positive correlation between increased NRBP1 expression and tumor stage, and lymph node metastasis was observed in 56 patients. High expression of NRBP1 was associated with poor prognosis and NRBP1 knockdown significantly inhibited cell proliferation and induced intrinsic apoptosis in vitro. Moreover, we also found that NRBP1 knockdown significantly suppress tumor growth in xenograft mouse model. Taken together, these data suggest that NRBP1 plays a critical role in the development of bladder cancer and may represent a potential target for bladder cancer treatment.

AbstractPurposeTo test the effect of tumor location (urachal vs. non-urachal) on cancer-specific mortality (CSM) in patients with adenocarcinoma of the urinary bladder (ADKUB).Materials and methodsWithin the Surveillance, Epidemiology, and End Results registry (2004 –2016), we identified patients with non-metastatic (≤ T4N0M0) ADKUB. Stratification was made according to tumor location: urachal vs. non-urachal ADKUB. Kaplan–Meier plots and multivariable Cox regression models were fitted before and after 1:3 propensity score (PS) matching and separate Cox r egression models were refitted before and after inver...

We report a unique case of a 60-year-old woman developing endometrial cancer in a uterine deposit 18 years after she had undergone laparoscopic subtotal hysterectomy with morcellation for benign pathology. She had used unopposed estrogen as menopausal hormone therapy. She presented with a pelvic mass that was causing pressure symptoms. On imaging, the mass had an enhancing vascular nodular component and appeared to abut normal ovaries and the residual cervix. She proceeded to laparotomy, where a 12 cm pelvic mass was found morbidly adherent to the bladder anteriorly and to the cervical stump. The pelvic mass was excise...

CONCLUSIONS: There was a low rate of postponed instillations (4.4%). The main reasons, namely an untreated UAC and a positive dipstick test, based on the jurisprudence, are not included in the latest CC-AFU guidelines. LEVEL OF EVIDENCE: 3. PMID: 31953014 [PubMed - as supplied by publisher]

This report describes the case of a 20 years old man who was diagnosed with a mass involving the small intestine and bladder during the course of investigations for faecaluria and abdominal pain. Histopathological examination of the biopsies during cystoscopy revealed: muscle invasive transitional cell carcinoma, while the computerized tomography scan had confirmed the enterovesical fistula.The patient was traited by Radical cystectomy with extended pelvic lymph node dissection and ileocecal resection as ultimate curative treatment.

Authors: Borgna V, Vidal I, Castillo OA Abstract OBJECTIVE: To compare peri-operative and mid-term oncological outcomes between Open radical cystectomy (ORC) and Laparoscopic radical cystectomy (LRC). METHODS: A retrospective cohort was assembled, in which 182 patients had been subjected consecutively to Radical Cystectomy (RC) for treatment of muscle-invasive bladder cancer (MIBC) between 2000 and 2010 in a single center. Two cohorts were included: ORC (n=83) and LRC (n=99). All the RCs were performed by the same surgeon. Perioperatory complications were registered according to Clavien-Dindo classification. We...

Nature Reviews Urology, Published online: 17 January 2020; doi:10.1038/s41585-019-0263-6An energetic interplay between tumour and immune cells leads to metabolic competition in the tumour ecosystem, an effect that could be targeted to boost immune checkpoint inhibition. In this Review, the authors discuss cancer cell and immune cell metabolism and consider the potential therapeutic targets within these processes.

Researchers in Spain have discovered a drug combination showing potential in treating the most difficult-to-treat type of malignant mesothelioma. Selumetinib and AZD8186, already being studied separately in clinical trials for other cancers, displayed efficacy when used in combination on mesothelioma of the sarcomatoid cell type. Researchers at the Spanish National Cancer Research Centre made the discovery during their study using mice models and human tumor cells in the laboratory. “The findings, we hope, are relevant,” Dr. Paco Real, who led the study, told The Mesothelioma Center at Asbestos.com. “We d...
