CBMR researcher won 22.000 euros to study rare neurological disease

Clévio Nóbrega, CBMR researcher and professor at the Department of Biomedical Sciences and Medicine (University of Algarve), obtained a 22.000 euros grant to study, over the next two years, Type 2 Cerebellar Ataxia, a rare neurological disease, without cure, that affects balance, coordination and speech.

The project, entitled “Neuroprotective therapeutic approach of Spinocerebellar ataxia type 2: pharmacological targeting of AMPK,” is funded by ATAXIA UK, a private, non-profit institution, that seeks to help patients and families affected by the disease.

The objective of the research, to be developed at the CBMR, in collaboration with the CNC – Center for Neurosciences and Cell Biology, is ambitious: to test an existing drug authorized for human use, in order to delay the progression of the disease.

At the moment there isn’t no treatment for this disease, only symptomatic treatments, incapable of delaying or preventing its progression.

So, Clévio Nóbrega and his team may take an important step in the treatment of the disease since the applicability of the drug may be accelerated because it isn’t an experimental drug.

Starting in october 2017, the project of Clévio Nóbrega is part of a series of innovative projects around the world that seek, through the financing of their research, to develop treatments and alternatives in the scope of the various types of Ataxias.

HeartExpress – technology for the heart

Heart development is a highly complex process with a series of precisely spatially and temporally ordered events on molecular level. To understand how these events are controlled and coordinated, it is necessary to study the underlying gene expression and its regulation. To help researchers in this formidable task, we have established HeartEXpress, a web-based platform for the analysis of integrated expression datasets associated with cardiomyogenesis. The current version comprises human and murine gene expression data from independent microarray experiments for stem cell differentiation, in vitro or in vivo reprogramming, in the context of cardiomyogenesis, and heart development. We hope that this resource will support the development of new therapies in cardiac regenerative medicine.

What is HeartEXpress?
HeartEXpress is a database that comprises published human and murine gene expression data from various microarray experiments for stem cell differentiation, in vitro or in vivo reprogramming in the context of cardiomyogenesis as well as heart development.

Why HeartEXpress?
Genome wide expression profiling of cardiogenesis in vivo and surrogate processes in vitro have delivered a detailed picture of molecular events important for the constitution of heart cells. However, the generated data remained difficult to access and analyze for many individual researchers, as they were dispersed across various repositories. HeartExpress can help here by providing an unique platform integrating various microarray studies for human and mouse with relevance for cardiogenesis.

HeartEXpress Data
At present, HeartEXpress integrated expression data from 15 mouse studies and 8 human studies with a total of 131 experimental conditions. These expression datasets cover more than 20000 genes in mouse and more than 19000 genes in human. Data sets were classified according to organisms and types of experiment and integrated data from both organisms and different types of studies.

What is HeartEXpress useful for?
For genes of interest, HeartEXpress enables the simultaneous inspection of expression data from many individual experiments obtained with different transcriptomic technologies. It allows query for multiple gene symbols and offers the option to download data as table for further analysis or presentation.

Moreover, HeartEXpress provides clustered gene expression data and correlation between genes. These feature help to identifiy co-expression patterns of genes indicating a common regulation and function during differentiation, reprogram-ming or heart development. Such approach may be useful for:
– Assigning functions to genes that have not been yet associated to heart development or heart morphology;
– Prioritize genes for experimental characterization
– Generate new research hypotheses

HeartEXpress can be utilized in an intuitive way and has a “step-by-step” instructions on its Help page as well as a table containing information about the studies integrated in the database.

Clévio Nóbrega publishes on British Medical Bulletin

Clévio Nóbrega, CBMR researcher, published recently on the British Medical Bulletin the article: “The contribution of genetics and environment to obesity”.

Know more about the article here.

Abstract: Obesity is a global health problem mainly attributed to lifestyle changes such as diet, low physical activity or socioeconomics factors. However, several evidences consistently showed that genetics contributes significantly to the weight-gain susceptibility.

Areas of controversy: After more than 10 years of investigation on the genetics of obesity, the variants found associated with obesity represent only 3% of the estimated BMI-heritability, which is around 47–80%. Moreover, genetic factors per sewere unable to explain the rapid spread of obesity prevalence.
Growing points: The integration of multi-omics data enables scientists having a better picture and to elucidate unknown pathways contributing to obesity.
Areas timely for developing research: New studies based on case–control or gene candidate approach will be important to identify new variants associated with obesity susceptibility and consequently unveiling its genetic architecture. This will lead to an improvement of our understanding about underlying mechanisms involved in development and origin of the actual obesity epidemic. The integration of several omics will also provide insights about the interplay between genes and environments contributing to the obese phenotype.

Inês Araújo and Ana Isabel Santos publish on The Antioxid Redox Signal Journal

Inês Araújo and Ana Isabel Santos, CBMR researchers, published recently on the Antioxid Redox Signal Journal the article: “S-nitrosylation of Ras mediates nitric oxide dependent post-injury neurogenesis in a seizure model”.

Know more about the article here.

Abstract: Nitric oxide (NO) is involved in the upregulation of endogenous neurogenesis in the subventricular zone and in the hippocampus after injury. One of the main neurogenic pathways activated by NO is the ERK/MAPK pathway, downstream of the EGF receptor. However, the mechanism by which NO stimulates cell proliferation through activation of the ERK/MAPK pathway remains unknown, although p21Ras seems to be one of the earliest targets of NO. Here, we aimed to study the possible neurogenic action of NO by post-translational modification of p21Ras as a relevant target for early neurogenic events promoted by NO in neural stem cells (NSC).

Results: We show that NO caused S-nitrosylation of p21Ras in Cys118, which triggered downstream activation of the ERK/MAPK pathway and proliferation of NSC. Moreover, in cells overexpressing a mutant Ras in which Cys118 was replaced by a serine -C118S-, cells were insensitive to NO, and no increase in S-nitrosylation, in ERK phosphorylation or in cell proliferation were observed. We also show that, following seizures, in the presence of NO derived from inducible nitric oxide synthase, there was an increase in p21Ras cysteine modification concomitant with the previously described stimulation of proliferation in the dentate gyrus.

Innovation: Our work identifies p21Ras and its S-nitrosylation as an early target of NO during signaling events that lead to NSC proliferation and neurogenesis.

Conclusion: Our data highlight Ras S-nitrosylation as an early event leading to NSC proliferation, and may provide a target for NO-induced stimulation of neurogenesis with implications for brain repair.
