Modificación de histonas: para que suceda, la larga cadena de ADN tiene que enrollarse en las estructuras de proteínas, las histonas. Así se forma una estructura de
cromatina
. Si está muy apretada, las células no pueden leer la información de esa secuencia.

Histone modification — since the DNA is extremely long as compared to the size of the cell nucleus, it needs to be wrapped around protein structures called “histones” in order to fit in. And in this way, it forms a chromatin structure. When this wrap is really tight, the information in the sequence cannot be read by the cell. If, on the contrary, the ties between the histones become loose, the information can be read and applied.

Histonmodifikation – um zu passen muss der lange DNA-Strang um Proteinstrukturen, "Histone", gewickelt werden. Auf diese Weise bildet sie eine Chromatinstruktur. Ist sie zu eng gewickelt, kann die Zelle die Informationen in dieser Sequenz nicht lesen. Sind die Bindungen zwischen diesen Histonen locker, werden die Informationen gelesen und angewendet.

Los investigadores encontraron que uno de los principales actores en la apertura de la
cromatina
y en la reparación del ADN dañado, la poli-ADP-ribosa (PAR), es clave para la síntesis de ATP en el núcleo.

comenta Miguel Beato, cap de grup al CRG i autor principal d’aquest estudi. Els investigadors van trobar que un dels principals actors en l’obertura de la cromatina i en la reparació de l’ADN danyat, la poliOADPOribosa (PAR), és clau per a la síntesi d’ATP en el nucli. L’enzim NUDIX5 utilitza els blocs d’ADPOribosa derivats de la degradació de PAR per generar ATP. Sense NUDIX5 no són possibles la remodelació de la cromatina, ni la reprogramació de l’expressió gènica i, per tant la cèl·lula no pot adaptarOse a l’estrès ni fer front a l’ADN danyat.

Un conocimiento profundo de cómo se regulan los procesos biológicos en los organismos vegetales requiere desvelar los mecanismos moleculares que controlan la expresión génica. En este trabajo describimos una técnica robusta para la identificación de los sitios de unión a DNA de proteínas de Arabidopsis mediante inmunoprecipitación de
cromatina
(ChIP).

The transcriptional regulation of specific genes is a crucial step in the response of plants to environmental factors and developmental cues. Progress in understanding how a variety of biological processes are regulated in plants depends on enlightening the molecular mechanisms that control gene expression. In this work we describe a straightforward procedure for the identification of the DNA-binding sites of Arabidopsis proteins of interest through Chromatin Immunoprecipitation (ChIP). This method has proven useful for the characterization of transcription factors, chromatin-related proteins, and posttranslationally modified histones.

This B·Debate, an initiative of Biocat and “la Caixa" Foundation, is co-organized with the Centre for Research in Agricultural Genomics (CRAG). Its main goal is to bring together renowned scientists working in plant development and defense, as well as experts on the incipient merging of both disciplines, which will provide new promising approaches to better understand stress-development trade-offs. This interdisciplinary meeting will cover the topics of plant-pathogen co-evolution and adaptation, hormone and signaling cascades, chromatin modifications and genome dynamics, cell biology and molecular single-cell approaches, among others.”

HALO veya SCSA testi (sperm kromatik yapı testi) fragmantasyon indeksini kavramaya olanak tanır. Sperm fragmantasyon indeksi diğer değerlendirmelerle birlikte yapıldığında, çocuk sahibi olmak isteyenlere, daha baştan doğru bir tedavi yöntemi seçilmesine yardımcı olur. Bu sayede aylarca sürecek başarısız bir tedavi uygulanmasının önüne geçilmiş olur. Nedenlerden biri spermlerin genetik materyalinde olan kopukluklardır/parçalanmalardır. Gün geçtikçe, her gün daha az kadın doğal yolla hamile kalabiliyor.

D'Incalci et al afirma que "Estudos exploraram o efeito de vitaminas e folatos predominantemente antioxidantes em eficácia ou toxicidade mediada por cisplatina e antraciclinas. A toxicidade de cisplatina em roedores foi melhorada pela vitamina E. O desenho de estudos clínicos de agentes dietéticos em combinação com os agentes citotóxicos têm sido muito heterogêneos e os resultados não foram conclusivos ". Eles concluem com cautela que" enquanto as experiências pré-clínicas sugerem um benefício potencial de certos agentes alimentares, a evidência que emana dos estudos clínicos não permite conclusões firmes. Explorar doses fisiológicas de agente dietético e incluir medidas farmacocinéticas e farmacodinâmicas ".

She studied Biomedicine and Physiological Sciences at the Faculty of Medicine and the Institute of Physiology at the Autonomous University of Puebla (BUAP). She is currently completing her third year of PhD in Natural Sciences (Dr. rer. Nat. Doktor der Naturwissenschaften) at the Max Planck Institute for Heart and Lung Research (MPI-HLR) in Bad Nauheim, and the University of Giessen, Germany. Her research includes the analysis of epigenetic mechanisms that modulate the onset and persistence of pulmonary diseases such as Idiopathic Pulmonary Fibrosis. The approach proposed at the Epigenetics of Lung Cancer group, by Dr. Guillermo Barreto, is the integration of transcriptomics, proteomics and non-coding RNAs databases to analyze the role of small RNAs (microRNAs) as regulators of transcription and chromatin structure. In 2015, she obtained her certification in two doctoral programs, Molecular Biology and Medicine of the Lung (MBML, Excellence Cluster, JLU Giessen) and International Research School MPI (IMPRS-HLR).

According to an article published in the journal Proteomics (9(4):1004-17), certain human spermatozoon nuclear proteins associated with chromatin have epigenetic potential. This means that it may play a key role in the activation of some genes during initial embryonic development. The study was carried out by Dr. Rafael Oliva and Dr. Sara Mateo of the IDIBAPS-Hospital Clínic Human Genetics Research group, and Dr. Josep María Estanyol of the proteomics unit of the faculty of medicine at the University of Barcelona.
