Alveolar bone healing in rats: micro-CT, immunohistochemical and molecular analysis

J. appl. oral sci; 26 (), 2018
Abstract Alveolar bone healing after upper incisor extraction in rats is a classical model of preclinical studies. The underlying morphometric, cellular and molecular mechanism, however, remains imprecise in a unique study. Objectives The aim of this study was therefore to characterize the alveolar bon...

Identification of key genes involved in nasopharyngeal carcinoma

Abstract Introduction: Nasopharyngeal carcinoma is the most common cancer originating from the nasopharynx. Objective: To study the mechanisms of nasopharyngeal carcinoma, we analyzed GSE12452 microarray data. Methods: GSE12452 was downloaded from the Gene Expression Omnibus database and included 31 n...

Improvement of clavulanic acid production in Streptomyces clavuligerus F613-1 by using a claR-neo reporter strategy

Background: Streptomyces clavuligerus was the producer of clavulanic acid, claR, a pathway-specific transcriptional regulator in S. clavuligerus, positively regulates clavulanic acid biosynthesis. In this study, the promoter-less kanamycin resistance gene neo was fused with claR to obtain strain NEO from...

Conversion to Mycophenolate Mofetil Monotherapy in Liver Recipients: Calcineurin Inhibitor Levels are Key

Ann. hepatol; 16 (1), 2017
Abstract: The use of calcineurin inhibitors (CNI) after liver transplantation is associated with post-transplant nephrotoxicity. Conversion to mycophenolate mofetil (MMF) monotherapy improves renal function, but is related to graft rejection in some recipients. Our aim was to identify variables associate...

Distinct characteristics of nasal polyps with and without eosinophilia

Abstract Introduction Eosinophilic and noneosinophilic Nasal polyps (NPs) are different subtypes of NPs and require different treatment methods. Objective To compare the histologic characteristics, mRNA and protein expression between Nasal Polyps with and without eosinophilia. Methods NPs tissues were...

The role of Osterix protein in the pathogenesis of peripheral ossifying fibroma

Abstract Peripheral ossifying fibroma (POF) is a reactive lesion of oral tissues, associated with local factors such as trauma or presence of dental biofilm. POF treatment consists of curettage of the lesion combined with root scaling of adjacent teeth and/or removal of other sources of irritants. This s...

BRD4 inhibition suppresses cell growth, migration and invasion of salivary adenoid cystic carcinoma

Biol. Res; 50 (), 2017
BACKGROUND: Bromodomain-containing protein 4 (BRD4) inhibition is a new therapeutic strategy for many malignancies. In this study, we aimed to explore the effect of BRD4 inhibition by JQ1 on in vitro cell growth, migration and invasion of salivary adenoid cystic carcinoma (SACC). METHODS: The human norma...

Expression of e-cadherin and wnt pathway proteins betacatenin, apc, tcf-4 and survivin in gastric adenocarcinoma: clinical and pathological implication

ABCD (São Paulo, Impr.); 29 (4), 2016
ABSTRACT Background: Gastric cancer is the fifth most frequent cancer and the third most common cause of cancer-related deaths worldwide.It has been reported that Wnt/ betacatenin pathway is activated in 30-50% of these tumors. However,the deregulation of this pathway has not been fully elucidated. Ai...

Análise funcional de microRNAs e fatores de transcrição durante a diferenciação eritroide in vitro em pacientes com talassemia beta intermediária

As talassemias beta são caracterizadas pela redução parcial ou completa da síntese de cadeias da globina beta. Estudos mostraram que vários fatores de transcrição estão envolvidos na regulação da expressão de genes eritroides, incluindo o complexo transcricional de GATA1. Além disso, os micro...

Anormalidades esqueléticas da síndrome tricorrinofalangiana tipo I

Rev. bras. reumatol; 56 (1), 2016
Resumo A síndrome tricorrinofalangiana (STRF) tipo I é uma doença genética rara, relacionada com a mutação no gene TRPS1 do cromossomo 8. É caracterizada por anomalias craniofaciais e distúrbios na formação e maturação da matriz óssea. As características são cabelos ralos e quebradiços, t...
