Abstract:
A FBXO25 é parte de uma E3 ligase do tipo RING, (Really Interesting New Gene), oligomérica do tipo SCF, responsável pelo reconhecimento específico do substrato a ser degradado via Sistema Ubiquitina-Proteassoma (SUP). O SUP é o principal mecanismo proteolítico intracelular, responsável pela degradação de 80-90% das proteínas citosólicas e nucleares. A FBXO25 é capaz de formar um complexo SCF1 ativo (formado pela interação das proteínas Skp1, Cul1, Roc1 e uma proteína do tipo F-box), capaz de ubiquitinar seus substratos. Essa proteína se acumula no núcleo celular formando uma nova estrutura sub

Abstract:
A proteína FBXO25 é uma E3-ligase do tipo SCF, responsável pela seletividade da ligação da Ub à proteína substrato e pelo direcionamento da proteína marcada para o barril proteassomal 26s. Sabe-se que FBXO25 é capaz de interagir e ubiquitinar a proteína Elk-1 em células HEK293T e, assim, inibir a expressão de genes importantes na regulação da proliferação celular, como C-FOS e EGR-1, após estímulo com o mitógeno PMA. Aqui mostramos que FBXO25 atua em um outro ponto da via das MAPKs, modulando os níveis de fosforilação de ERK1/2. Por meio da utilização de células nocaute para FBXO25 (FBXO25KO)

Abstract:
Heart failure is associated with a high mortality rate and is one of the most prevalent diseases worldwide whereby susceptibility increases with age. The development of heart failure occurs over an extensive period of time in which arrhythmias and hypertrophy are both very prevalent manifestations throughout this progression. Arrhythmias are defined as an irregular rhythm originating from intracellular calcium dysregulation, which can be fatal. Cardiac hypertrophy is a compensatory condition induced by increased workload involving augmented cardiomyocyte growth accompanied by myocardial remode

Abstract:
Research performed over the last decade has highlighted the role of HDAC inhibitors (HDACis) as modulators of transcriptional activity and as a potential new class of therapeutic agents against many types of malignacies including breast cancer. These drugs inhibit histone deacetylases, leading to derepression of transcription of various genes that are important for cell cycle arrest and cell death. Trichostatin A (TSA) is one of the best established HDAC inhibitors and has been shown to exhibit potent differentiating and anti-proliferative properties. My data demonstrated that treatment of the

Abstract:
Parkinson's disease is a progressive neurodegenerative disorder of the central nervous system, manifesting with both motor and non-motor symptoms. Autosomal recessive mutations in the FBXO7 gene have been identified to cause a rapidly progressing early-onset form of PD. Canonically, FBXO7 functions as a substrate-recruiting subunit of the SCF-type E3 ubiquitin ligase. However, it also has a variety of other atypical functions, such as cell cycle regulation, proteasome regulation, and mitophagy. The overall aim of this research was to characterise the functional role of FBXO7 in various in vitr

Abstract:
Parkinson’s Disease (PD) is the second most common neurodegenerative disorder after Alzheimer’s and old age is the strongest risk factor for developing PD. PD has traditionally been seen as a motor disorder, but its non-motor symptoms such as dysautonomia, sensory dysfunction, sleeping problems and neuropsychiatric features equally add to the disease burden. There is no cure for PD and this is probably a reflection of our poor understanding of the disease pathogenesis. One way of tackling this is to focus on the small, but significant number of PD patients with a family history compatible with

Abstract:
F-box only protein 7 (Fbxo7), a member of the F-box-only subfamily of FBPs, is a biologically and pathophysiologically important human protein that assumes many critical functions. The different functions of Fbxo7 depend on the formation of various multi-protein complexes. Possible interplay between different Fbxo7 functions further complicate the protein-protein interaction networks involved in Fbxo7 biology. Although significant progresses have been made to understand the functions, regulation, specificity, and protein interaction network of Fbxo7, a myriad of questions remain to be answere

Abstract:
Cette étude a été conçue pour identifier les protéines qui interagissent potentiellement avec Déméthylase 4A spécifique de la lysine (KDM4A) dans le contexte du cancer en utilisant l’essai d'identification de la biotine dépendante de la proximité 2 (BioID2). KDM4A est une lysine déméthylase et un régulateur épigénétique qui joue un rôle dans la carcinogenèse en favorisant la prolifération. Nous avons cherché à identifier l'interactome protéique de KDM4A dans la lignée cellulaire du cancer du col de l'utérus HeLa. Ces interactions protéiques ont été caractérisées en fonction de leur dépendance

Abstract:
The F-box and leucine-rich repeat factor (FBXL4) locus is altered in two distinct diseases, a pediatric mitochondrial encephalopathy associated with early death, and the highly aggressive hematological malignancy T-cell Acute Lymphoblastic Leukemia (T-ALL). As an F-box protein, FBXL4 is predicted to target specific protein substrates for proteasomal degradation. Notably, not much is known about the roles of FBXL4 in homeostasis or disease, and thus I generated conditional Fbxl4 knockout mice to characterize the contributions of Fbxl4 to mitochondrial encephalopathy and to T-ALL. Homozygous mut

Abstract:
O cancro do cólon e recto familiar do tipo X (FCCTX) descreve as famílias HNPCC que preenchem os CA mas não apresentam mutações germinais nos genes MMR e cujos tumores são microssatélites estáveis. Não são ainda conhecidas causas moleculares que expliquem a susceptibilidade para o desenvolvimento de cancro do cólon na grande maioria das famílias FCCTX. Assim, o presente projecto pretendeu identificar genes candidatos/variantes específicas em genes candidatos que possam estar envolvidos na susceptibilidade para o cancro do cólon e recto familiar do tipo X (FCCTX).
