Active human retrotransposons: Variation and disease

Mobile DNAs, also known as transposons or 'jumping genes', are widespread in nature and comprise an estimated 45% of the human genome. Transposons are divided into two general classes based on their transposition intermediate (DNA or RNA). Only one subclass, the non-LTR retrotransposons, which includes the Long INterspersed Element-1 (LINE-1 or L1), is currently active in humans as indicated by 96 disease-causing insertions. The autonomous LINE-1 is capable of retrotransposing not only a copy…

Genetic architecture in autism spectrum disorder

Autism spectrum disorder (ASD) is characterized by impairments in reciprocal social interaction and communication, and by restricted and repetitive behaviors. Family studies indicate a significant genetic basis for ASD susceptibility, and genomic scanning is beginning to elucidate the underlying genetic architecture. Some 5-15% of individuals with ASD have an identifiable genetic etiology corresponding to known chromosomal rearrangements or single gene disorders. Rare ( < 1% frequency) de novo…

MTOR in aging, metabolism, and cancer

The target of rapamycin (TOR) is a highly conserved serine/threonine kinase that is part of two structurally and functionally distinct complexes, TORC1 and TORC2. In multicellular organisms, TOR regulates cell growth and metabolism in response to nutrients, growth factors and cellular energy. Deregulation of TOR signaling alters whole body metabolism and causes age-related disease. This review describes the most recent advances in TOR signaling with a particular focus on mammalian TOR (mTOR) in…

MiRNA profiling of cancer

A steadily growing number of studies have shown that microRNAs have key roles in the regulation of cellular processes and that their dysregulation is essential to keep the malignant phenotype of cancer cells. The distorted and unique expression profile of microRNAs in different types and subsets of tumor coupled with their presence in biological fluids make of microRNAs an attractive source of sensitive biomarkers. Here, we will discuss how microRNA profiles are altered in cancer, highlighting…

Mechanisms for recurrent and complex human genomic rearrangements

During the last two decades, the importance of human genome copy number variation (CNV) in disease has become widely recognized. However, much is not understood about underlying mechanisms. We show how, although model organism research guides molecular understanding, important insights are gained from study of the wealth of information available in the clinic. We describe progress in explaining nonallelic homologous recombination (NAHR), a major cause of copy number change occurring when…

Combinatorial complexity in chromatin structure and function: Revisiting the histone code

Covalent modifications of histone proteins play key roles in transcription, DNA repair, recombination, and other such processes. Over a hundred histone modifications have been described, and a popular idea in the field is that the function of a single histone mark cannot be understood without understanding its combinatorial co-occurrence with other marks, an idea generally called the 'histone code hypothesis.' This idea is hotly debated, with increasing biochemical evidence for chromatin…

Existence and consequences of G-quadruplex structures in DNA

While the discovery of B-form DNA 60 years ago has defined our molecular view of the genetic code, other postulated DNA secondary structures, such as A-DNA, Z-DNA, H-DNA, cruciform and slipped structures have provoked consideration of DNA as a more dynamic structure. Four-stranded G-quadruplex DNA does not use Watson-Crick base pairing and has been subject of considerable speculation and investigation during the past decade, particularly with regard to its potential relevance to genome…

Autophagy and human disease: Emerging themes

Malfunction of autophagy, the process that mediates breakdown and recycling of intracellular components in lysosomes, has been linked to a variety of human diseases. As the number of pathologies associated with defective autophagy increases, emphasis has switched from the mere description of the status of autophagy in these conditions to a more mechanistic dissection of the autophagic changes. Understanding the reasons behind the autophagic defect, the immediate consequences of the autophagic…

Enhancer and promoter interactions-long distance calls

In metazoans, enhancers of gene transcription must often exert their effects over tens of kilobases of DNA. Over the past decade it has become clear that to do this, enhancers come into close proximity with target promoters with the looping away of intervening sequences. In a few cases proteins that are involved in the establishment or maintenance of these loops have been revealed but how the proper gene target is selected remains mysterious. Chromatin insulators had been appreciated as…

TERT promoter mutations in cancer development

Human telomerase reverse transcriptase (TERT) encodes a rate-limiting catalytic subunit of telomerase that maintains genomic integrity. TERT expression is mostly repressed in somatic cells with exception of proliferative cells in self-renewing tissues and cancer. Immortality associated with cancer cells has been attributed to telomerase over-expression. The precise mechanism behind the TERT activation in cancers has mostly remained unknown. The newly described germline and recurrent somatic…

Recent developments in the genetics of autism spectrum disorders

The last several years have marked a turning point in the genetics of autism spectrum disorder (ASD) due to rapidly advancing genomic technologies. As the pool of bona fide risk genes and regions accumulates, several key themes have emerged: these include the important role of rare and de novo mutation, the biological overlap among so-called syndromic and 'idiopathic' ASD, the elusive nature of the common variant contribution to risk, and the observation that the tremendous locus heterogeneity…

The ciliopathies: A transitional model into systems biology of human genetic disease

The last decade has witnessed an explosion in the identification of genes, mutations in which appear sufficient to cause clinical phenotypes in humans. This is especially true for disorders of ciliary dysfunction in which an excess of 50 causal loci are now known; this discovery was driven partly by an improved understanding of the protein composition of the cilium and the co-occurrence of clinical phenotypes associated with ciliary dysfunction. Despite this progress, the fundamental challenge…

Mutational signatures: The patterns of somatic mutations hidden in cancer genomes

All cancers originate from a single cell that starts to behave abnormally due to the acquired somatic mutations in its genome. Until recently, the knowledge of the mutational processes that cause these somatic mutations has been very limited. Recent advances in sequencing technologies and the development of novel mathematical approaches have allowed deciphering the patterns of somatic mutations caused by different mutational processes. Here, we summarize our current understanding of mutational…

Small RNAs in development - insights from plants

microRNAs (miRNAs) and small interfering RNAs (siRNAs), which constitute two major classes of endogenous small RNAs in plants, impact a multitude of developmental and physiological processes by imparting sequence specificity to gene and genome regulation. Although lacking the third major class of small RNAs found in animals, Piwi-interacting RNAs (piRNAs), plants have expanded their repertoire of endogenous siRNAs, some of which fulfill similar molecular and developmental functions as piRNAs in…

Transcription factories: Genetic programming in three dimensions

Among the most intensively studied systems in molecular biology is the eukaryotic transcriptional apparatus, which expresses genes in a regulated manner across hundreds of different cell types. Several studies over the past few years have added weight to the concept that transcription takes place within discrete 'transcription factories' assembled inside the cell nucleus. These studies apply innovative technical approaches to gain insights into the molecular constituents, dynamical behaviour…

MicroRNAs in the ionizing radiation response and in radiotherapy

Radiotherapy is a form of cancer treatment that utilizes the ability of ionizing radiation to induce cell inactivation and cell death, generally via inflicting DNA double-strand breaks. However, different tumors and their normal surrounding tissues are not equally sensitive to radiation, posing a major challenge in the field: to seek out factors that influence radiosensitivity. In this review, we summarize the evidence for microRNA (miRNA) involvement in the radioresponse and discuss their…

ECM-modulated cellular dynamics as a driving force for tissue morphogenesis

The extracellular matrix (ECM) plays diverse regulatory roles throughout development. Coordinate interactions between cells within a tissue and the ECM result in the dynamic remodeling of ECM structure. Both chemical signals and physical forces that result from such microenvironmental remodeling regulate cell behavior that sculpts tissue structure. Here, we review recent discoveries illustrating different ways in which ECM remodeling promotes dynamic cell behavior during tissue morphogenesis.…

Hedgehog signaling from the primary cilium to the nucleus: An emerging picture of ciliary localization, trafficking and transduction

The unexpected connection between cilia and signaling is one of the most exciting developments in cell biology in the past decade. In particular, the Hedgehog (Hh) signaling pathway relies on the primary cilium to regulate tissue patterning and homeostasis in vertebrates. A central question is how ciliary localization and trafficking of Hh pathway components lead to pathway activation and regulation. In this review, we discuss recent studies that reveal the roles of ciliary regulators,…

A view of nuclear Polycomb bodies

Polycomb group (PcG) proteins are concentrated in nuclear foci called PcG bodies. Although some of these foci are due to the tendency of PcG binding sites in the genome to occur in linear clusters, distant PcG sites can contact one another and in some cases congregate in the same PcG body when they are repressed. Experiments using transgenes containing PcG binding sites reveal that co-localization depends on the presence of insulator elements rather than of Polycomb Response Elements (PREs) and…

Organoid cultures for the analysis of cancer phenotypes

Preclinical models of cancer are essential for a basic understanding of cancer biology and its translation into efficient treatment options for affected patients. Cancer cell lines and xenografts derived directly from primary human tumors have proven very valuable in fundamental oncology research and anticancer drug discovery. Both models inherently comprise advantages and caveats that have to be accounted for. We will outline in these and discuss primary patient derived organoids as third…

Genomic imprinting: Recognition and marking of imprinted loci

Genomic imprinting is an epigenetic process resulting in the monoallelic parent-of-origin-specific expression of a subset of genes in the mammalian genome. The parental alleles are differentially marked by DNA methylation during gametogenesis when the genomes are in separate compartments. How methylation machinery recognizes and differentially modifies these imprinted regions in germ cells remains a key question in the field. While studies have focused on determining a sequence signature that…

Genetic and epigenetic determinants of DNA replication origins, position and activation

In the genome of eukaryotic cells, DNA synthesis is initiated at multiple sites called origins of DNA replication. Origins must fire only once per cell cycle and how this is achieved is now well understood. However, little is known about the mechanisms that determine when and where replication initiates in a given cell. A large body of evidence indicates that origins are not equal in terms of efficiency and timing of activation. Origin usage also changes concomitantly with the different cell…
