1alpha,25-Dihydroxyvitamin D3 [1,25(OH)2D3] regulates calcium homeostasis and controls cellular differentiation and proliferation. The vitamin D receptor (VDR) is a ligand-regulated transcription factor that recognizes cognate vitamin D response elements (VDREs) formed by direct or everted repeats of PuG(G/T)TCA motifs separated by 3 or 6 bp (DR3 or ER6).(More)
BACKGROUND Robot-assisted endoscopic transaxillary thyroidectomy is an emerging surgical technique that needs to be evaluated in European patients. We evaluate the feasibility and preliminary results of our experience of this technique in a cohort of patients from within a single European university hospital (Nîmes, France). METHODS We performed a(More)
BACKGROUND It is no longer adequate to choose reference genes blindly. We present the first study that defines the suitability of 12 reference genes commonly used in cancer studies (ACT, ALAS, B2M, GAPDH, HMBS, HPRT, KALPHA, RPS18, RPL27, RPS29, SHAD and TBP) for the normalization of quantitative expression data in the field of head and neck squamous cell(More)
BACKGROUND Clinical efficacy of chemotherapy in colorectal cancer is subjected to broad inter-individual variations leading to the inability to predict outcome and toxicity. The topoisomerase I inhibitor irinotecan (CPT-11) is worldwide approved for the treatment of metastatic colorectal cancer and undergoes extensive peripheral and tumoral metabolism. PXR(More)
CONCLUSIONS Conventional radiotherapy with concurrent cisplatin is significantly superior to induction cisplatin fluorouracil chemotherapy followed by radiotherapy in terms of laryngeal preservation in patients with T3 hypopharyngeal carcinoma. Despite a high rate of laryngeal preservation no survival benefit was recorded in this selected population. (More)
BACKGROUND To date, more than 60 gene expression profiling (GEP) studies have been published in the field of head and neck squamous cell carcinoma (HNSCC) with variable objectives, methods, and results. METHODS The purpose of this study was to present a state-of-the-art review of GEP in HNSCC focusing on the current advances and perspectives for clinical(More)
AIM To determine whether the use of 3D anatomical models is helpful to students and enhances their anatomical knowledge. METHODS First year undergraduate students on the speech therapy or hearing aid practitioner courses attended either a lecture alone or a lecture followed by a 3D anatomy based tutorial, the latter which was also attended by ENT(More)
Gemcitabine (2',2'-difluorodeoxycytidine) is a major antimetabolite cytotoxic drug with a wide spectrum of activity against solid tumors. Hepatic elimination of gemcitabine depends on a catabolic pathway through a deamination step driven by the enzyme cytidine deaminase (CDA). Severe hematologic toxicity to gemcitabine was reported in patients harboring(More)
BACKGROUND Analysis of 23 published transcriptome studies allowed us to identify nine genes displaying frequent alterations in HNSCC (FN1, MMP1, PLAU, SPARC, IL1RN, KRT4, KRT13, MAL, and TGM3). We aimed to independently confirm these dysregulations and to identify potential relationships with clinical data for diagnostic, staging and prognostic purposes(More)
Although 1,25-dihydroxyvitamin D3 (1,25D3) and retinoic acid (RA) have distinct developmental and physiological roles, both regulate the cell cycle. We provide molecular and genomic evidence that their cognate nuclear receptors regulate common genes through everted repeat TGA(C/T)TPyN8PuG(G/T)TCA (ER8) response elements. ER8 motifs were found in the(More)
