Abstract:
Breast cancer it is the most common type of cancer and leading cause of cancer mortality among women worldwide. Women who inherit mutations in the breast cancer 1 susceptibility gene (BRCA1) are five times more likely to develop breast cancer than women who do not. However, only ~5-10% of breast cancer cases are due to germline mutations in tumor suppressor genes. There are currently no targeted therapies available triple negative breast cancers (TNBC), which often lack BRCA1 expression. BRCA1 is epigenetically silenced by the activated aryl-hydrocarbon receptor (AhR), suggesting that dietary

Abstract:
Cancer is the 2nd most common cause of death in our society and is associated with high morbidity and costs. The word ‘cancer’ amalgamates the complex interplay between cells which have acquired genetic alterations leading to uncontrolled proliferation, i.e. the malignant cells, and genetically ‘normal’ host cells, i.e. stromal cells, vascular cells and inflammatory cells which all acquire modified biological phenotypes in the presence of malignant cells. This community of cells and their secreted proteins defines the tumour microenvironment. Stromal cells in the tumour microenvironment displa

Abstract:
The risk of breast cancer transiently increases immediately following pregnancy. Hispanic women have one of the highest rates of postpartum breast cancers of all racial/ethnic minority groups in the US. The biology that underlies this risk window and the effect on the natural history of the disease is unknown. MicroRNAs (miRNAs) are small non-coding RNAs that have been shown to be dysregulated in breast cancer. In this study, we measured the miRNA expression of 56 tumors from a case series of multiparous Hispanic women and assessed the pattern of expression by time since last full-term pregnan

Abstract:
Changes in the epigenetic landscape are widespread in neoplasia, with de novo methylation and histone repressive marks commonly occurring in association with gene silencing. However, understanding the dynamics of epigenetic changes is often hindered due to the absence of adequate in vitro model systems that accurately reflect events occurring in vivo. Human mammary epithelial cells (HMECs) grown under standard culture conditions enter a growth arrest termed selection, but a subpopulation is able to escape from arrest and continue to proliferate. These cells, called post-selection cells, hav

Abstract:
Epigenetics plays an important role in carcinogenesis with heritable changes in DNA methylation and histone modifications intricately linked to the initiation, promotion, and progression of cancer. Evidence shows that a number of chemical and physical agents can induce epigenetic changes during carcinogenesis. Two such agents, estrogen and ionizing radiation, are generally recognized as being carcinogenic. Yet the epigenetic repercussions of these carcinogens remain relatively unknown. More importantly, the combined effect of these carcinogens has never been addressed in vivo from an epigeneti

Colorectal cancer (CRC) arises from a multi-step process leading to the progressive accumulation of genetic and epigenetic mutations, thus causing deregulation in homeostasis followed by neoplastic transformation.Epigenetic and genetic alterations are able to induce a constitutive activation of the WNT signaling pathway, whose aberrant activity converges into deregulation of proliferation, differentiation and cell death pathways. The most common causes of WNT pathway hyper-activation are APC loss of function, or b-catenin constitutive activation mutations. Despite this knowledge of aberrant WN

Integrin α6β4 is upregulated in pancreatic carcinoma, where signaling promotes metastatic properties, in part by altering the transcriptome.

I found that signaling from integrin α6β4 dramatically upregulates expression of amphiregulin (AREG) and epiregulin (EREG), ligands for the epidermal growth factor receptor (EGFR), and that these ligands promote pancreatic carcinoma invasion.

Reinforcing this, tRNA levels are tightly regulated to match the codon usage patterns of a given cell type or cellular status to meet the cellular specific needs and adapt to stress.

Il est clairement établi que les altérations génétiques et épigénétiques sont des événements communs dans les cancers de la prostate, se traduisant par l’expression aberrante de gènes critiques. La méthylation des histones participe à la régulation de l’expression des gènes dans la cellule. La marque épigénétique H3K27me3 est associée à la répression génique et se trouve dérégulée dans les cancers de la prostate. Ses niveaux sont déterminés par l’équilibre entre les activités de la

Abstract:
Epigenetic states constitute heritable features of the chromatin to regulate when, where and how genes are expressed in the developing conceptus. A special case of epigenetic regulation, genomic imprinting, is defined as parent of origin-dependent monoallelic expression. The Igf2-H19 locus is considered as paradigm of genomic imprinting with a growth-promoting gene, Igf2, expressed paternally and a growth antagonist, H19 encoding a non-coding transcript, expressed only from the maternal allele. The monoallelic expression patterns are regulated by the epigenetic status at an imprinting control

Abstract:
Cancer is considered nowadays a genetic and epigenetic disease. Aberrancies in epigenetic marks in DNA and histone tails together with alterations in epigenetic regulators responsible of catalyzing these marks have been shown to be crucial in tumorigenesis. These epigenetic regulators are commonly known as writers, readers and erasers. The plasticity of the epigenetic landscape compared to the unchangeable nature of genetic alterations has led to an increasing interest in the last years in finding specific drugs able to modulate and correct the epigenetic aberrancies present in tumors.

Abstract:
Nicht-kleinzelliger Lungenkrebs (NSCLC) hat bis heute einen hohen medizinischen Bedarf an effektiveren Therapien. Inhibitoren der Bromodomain and extra-terminal domain (BET) Familie wie JQ1 wirken in verschiedenen Krebsarten, einschließlich Lungenkrebs. Während ihre Aktivität auf die Expression von Onkogenen wie c-Myc in vielen Studien untersucht wurde, bleibt der Effekt von BET-Inhibition auf den Apoptose Signalweg weitgehend unbekannt. In dieser Arbeit wurde die Aktivität von BET-Inhibitoren auf den Zellzyklus und auf Komponenten der Apoptose-Antwort der Zelle untersucht. Genomweite Transkri
