The Transcription Factors TBX2 and TBX3 Interact with Human Papillomavirus 16 (HPV16) L2 and Repress the Long Control Region of HPVs

2013

ABSTRACT The minor capsid protein L2 of human papillomaviruses (HPVs) has multiple functions during the viral life cycle. Although L2 is required for effective invasion and morphogenesis, only a few cellular interaction partners are known so far. Using yeast two-hybrid screening, we identified the transcription factor TBX2 as a novel interaction partner of HPV type 16 (HPV16) L2. Coimmunoprecipitations and immunofluorescence analyses confirmed the L2-TBX2 interaction and revealed that L2 also interacts with TBX3, another member of the T-box family. Transcription of the early genes during HPV infection is under the control of an upstream enhancer and early promoter region, the long control r…

The Wilms' tumor suppressor gene (wt1) product regulates Dax-1 gene expression during gonadal differentiation.

1999

Gonadal differentiation is dependent upon a molecular cascade responsible for ovarian or testicular development from the bipotential gonadal ridge. Genetic analysis has implicated a number of gene products essential for this process, which include Sry, WT1, SF-1, and DAX-1. We have sought to better define the role of WT1 in this process by identifying downstream targets of WT1 during normal gonadal development. We have noticed that in the developing murine gonadal ridge, wt1 expression precedes expression of Dax-1, a nuclear receptor gene. We document here that the spatial distribution profiles of both proteins in the developing gonad overlap. We also demonstrate that WT1 can activate the D…

Tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors predominate as first-line therapy options for renal cell carcinoma. When first-line TKI therapy fails due to resistance development, an optimal second-line therapy has not yet been established. The present investigation is directed towards comparing the anti-angiogenic properties of the TKIs, sorafenib and axitinib on human endothelial cells (HUVECs) with acquired resistance towards the TKI sunitinib. HUVECs were driven to resistance by continuously exposing them to sunitinib for six weeks. They were then switched to a 24 h or further six weeks treatment with sorafenib or axitinib. HUVEC growth, as well as angiogenesis (tube…

Urinary bladder enlargement across nine rodent models of diabetes: correlations with glucose and insulin levels

2021

AbstractThe urinary bladder is markedly enlarged in the type 1 diabetes mellitus model of streptozotocin (STZ)-injected rats, but much less data exist for models of type 2 diabetes (T2DM). Diabetic polyuria has been proposed to explain bladder enlargement. We have collected data on bladder weight and blood glucose from 16 studies representing 9 distinct rodent diabetes (7 T2DM) and obesity models; some included arms with diets and/or pharmacological treatments. Data were analyzed for bladder enlargement and for correlations between bladder weight on the one and glucose levels on the other hand. Our data confirm major bladder enlargements in STZ rats, minor if any enlargement in fructose-fed…

Human Papillomavirus vaccination for the prevention of cervical and other related cancers

2011

Academic research described in the late 1980’s the causal association between human papillomavirus (HPV) and cervical cancer, later expanded to significant fractions of all other genital tract cancers in both genders as well as a proportion of the cancers of the oral cavity and oropharynx. Prophylactic phase III HPV vaccine trials have shown complete type specific vaccine efficacy against two HPV types, namely HPV 16 and 18, that together account for over 70% of cervical cancer worldwide. HPV vaccines have proven in trials to have an excellent safety record. Most developed populations have introduced HPV vaccines as part of their routine vaccination schemes and introduction into developing …

von Hippel-Lindau Protein-Mediated Repression of Tumor Necrosis Factor Alpha Translation Revealed through Use of cDNA Arrays

2003

Based on evidence that the von Hippel-Lindau (VHL) tumor suppressor protein is associated with polysomes and interacts with translation regulatory factors, we set out to investigate the potential influence of pVHL on protein translation. To this end, renal cell carcinoma (RCC) cells that either lacked pVHL or expressed pVHL through stable transfection were used to prepare RNA from cytosolic (unbound) and polysome-bound fractions. Hybridization of cDNA arrays using RNA from each fraction revealed a subset of transcripts whose abundance in polysomes decreased when pVHL function was restored. The tumor necrosis factor alpha (TNF-alpha) mRNA was identified as one of the transcripts that prefere…

Uncommon evolutions and complications of common benign liver lesions

2018

International audience; Frequently encountered on abdominal imaging studies, the majority of common benign liver lesions are asymptomatic, confidently diagnosed by imaging, and do not require further workup, follow-up, or treatment. The increasing use of multimodality liver imaging, has allowed the recognition of uncommon evolutions of common benign liver lesions such as size changes, fibrotic regression, and content and vascularization changes, and their complications such as rupture, hemorrhage, thrombosis, extrinsic compression, and malignancy. The purpose of this pictorial review is to describe and illustrate the incidence and diagnostic features of these uncommon evolutions and complic…

Robotic versus laparoscopic radical hysterectomy in early cervical cancer: A case matched control study

2018

Abstract Background This study aims at evaluating the feasibility, surgical outcome and oncological results observed after robotic radical hysterectomy (RH) compared to laparoscopy for patients with early stage cervical cancer (ECC) patients. Methods Between January 2010 and October 2016, 210 patients underwent RH for treatment of ECC: 70 underwent robotic approach (Cases), and 140 underwent laparoscopic approach (Controls). Results There was no statistically significant difference between the two approaches with regard to clinical patient characteristics and in terms of extent of RH and rate of pelvic and aortic lymphadenectomy. Operative time was significantly longer in the robotic versus…

Perioperative morbidity and rate of upstaging after laparoscopic staging for patients with locally advanced cervical cancer: results of a prospective…

2015

Objective The International Federation of Gynecology and Obstetrics (FIGO) staging for cervical cancer is based on clinical examination. Previous studies have demonstrated significant upstaging with surgical staging. However, no randomized trial has ever shown a survival benefit when radiation combined with chemoradiation (RCTX) is modified according to surgical staging. The objective of the study was to evaluate the feasibility and outcomes of surgical staging prior to radical RCTX treatment among patients with locally advanced cervical cancer in the setting of a larger, prospective, randomized study (the Uterus-11 study of the German Gynecologic Oncology Group). Study Design Between 2009 …

Mesh complications following prolapse surgery: management and outcome.

2011

Abstract Objective This is a description of complications following prolapse surgery with the use of alloplastic materials, the management and outcome. Study design 54 women have been referred to Mainz, urogynecology referral center due to complications following mesh-augmented prolapse surgery. Results The complaints who lead to the admission are expressed by the new terminology and standardized classification for complications arising directly from the insertion of prostheses and grafts in female pelvic floor surgery [1] . Pain (66.7%), mesh erosion (55.6%) and vaginal discharge (48.1%) were the most frequent complaints. Revision was performed after a median time of 27.2 months post mesh …
