about
In this issue of Cell Genomics, Akbari et al. describe a method to assign individual alleles to their parent-of-origin. The method does not require any parental DNA but rather utilizes chromosome-scale haplotyping and epigenetically imprinted regions to make the assignment. In the cover image, the process of determining the parent-of-origin using differential methylation of alleles at imprinted regions (iDMRs) in chromosomes is imagined as a circuit. Shown are chromosomes (11, 12, 16, 21, and 22) with imprinted loci as rows of colored dots (orange maternal, green paternal). Independent circuits connect the chromosomes with a maternal (orange line) and paternal (green line) origin. Cytogenetic bands are depicted as independent circuits, colored by the conventional banding pattern.

DNA sequencing read translation in high-dimensional space. The cover image was created when 672 bases of sequencing barcodes generated by three different single-cell RNA sequencing platforms were encoded as oriented triangles on the faces of three 7-dimensional cubes. Kijima et al. have developed a software tool that interprets DNA sequences to extract encoded information for additional biological analysis. The tool called, INTERSTELLAR, will facilitate development of sequencing-based experiments and sharing of data analysis pipelines.

about
Glioblastomas (GBMs) are notoriously heterogeneous, contributing to their aggressive phenotype. In this issue, LeBlanc et al. use single-cell genomic approaches to show that novel explant models of GBM largely retain the genetic and transcriptional heterogeneity of their parent tumors. Their findings highlight how detailed molecular characterization of model systems is a necessary first step to their informed use. The artwork depicts cellular heterogeneity as a kaleidoscope generated from immunofluorescence staining of the glial and neuronal markers MBP and NeuN (respectively) in a GBM patient-derived explant.

about
For more than 50 years, scientists have been trying to understand the relationship between DNA sequence, gene-expression phenotype and fitness to decipher principles of gene regulatory evolution. In this week’s issue, Eeshit Dhaval Vaishnav, Carl de Boer, Aviv Regev and their colleagues present a framework for understanding and engineering regulatory DNA sequences that takes a step towards this goal. The researchers built this framework around an ‘oracle’ they developed using a deep neural network model that predicts gene expression given a promoter DNA sequence. The neural network was trained using the expression measurements for tens of millions of promoter sequences. The result was an AI oracle that predicts expression from sequence well enough to study the evolutionary history and future evolvability of regulatory DNA sequences, as well as to design regulatory DNA sequences for synthetic biology applications. The cover offers a visual representation of the evolutionary properties of sequences at the extremes of the evolvability spectrum.

A view of Earth that captures the vision of the Earth BioGenome Project — understanding and conserving genetic diversity on a global scale. Continents from the Authagraph projection, which preserves areas and shapes, are represented as a double helix of 32,111 bases. Short sequences of 806 unique species, sequenced as part of EBP-affiliated projects, are mapped onto the double helix of the continent (or ocean) where the species is commonly found. The length of the sequence is the same for each species on a continent (or ocean) and the sequences are separated by short gaps. Individual bases of the sequence are colored by dots. Species appear along the path in alphabetical order (by Latin name) and the first base of the first species is identified by a small black triangle.

The sequencing of the dog genome, completed in 2005, revealed large overlaps between the dog and human genomes. Some of the patterns in dog-human homology—similarity arising from shared ancestry—are depicted here in a Circos diagram. Selected human (top, blue outer band) and dog (bottom, orange outer band) chromosomes are arranged around the circle, with bands connecting regions of homology between the two species. Where DNA on a dog chromosome matches human DNA, color-coded stripes indicate the relevant human chromosome. In "Genetics and the Shape of Dogs," Elaine A. Ostrander describes some results from the dog genome project, including detailed work on chromosome 15. The spray of colored ribbons on the cover illustration shows the pattern of connections between this chromosome and seven human chromosomes.

In influenza virus infected cells, eight viral genomic RNPs are assembled into progeny virions, which predominantly contain one copy of each. Using sets of fluorescence microscope images of four vRNPs, the likelihood that the subcellular distribution of one vRNP can be predicted from the distribution of another was estimated for all pairs of vRNPs with significant relationships. The thick base of the bands indicates the vRNP whose location can be used to predict the location of the vRNP indicated by the thin base. These pairwise and higher order relationships were used to infer the assembly network for all eight vRNPs.

Metagenomics data typically consist of a huge number of DNA sequence fragments from the genomes of microbial community members collected directly from an environment. Partial and sometimes complete genomes can be reconstructed and the metabolic capabilities of specific organisms revealed. In this issue, a study demonstrates how combining short- and long-read DNA sequencing technologies can improve genome recovery and microbial community analysis. The figure is a symbolic representation of the metagenomics analysis process in which the diverse genomes are recovered using short, and now also long, DNA sequencing read data, a process that conceptually resembles one of solving jigsaw puzzles.

about
Head and neck squamous cell carcinomas (HNSCC) are a genetically heterogeneous group of cancers with a poor survival rate. Lui and colleagues evaluated the mutation frequency of mitogenic pathways in HNSCCs and found that 30.5% of tumors harbored PI3K pathway mutations. Patient-derived tumorgrafts with hotspot and noncanonical PIK3CA mutations were highly sensitive to PI3K inhibitors. Pickering and colleagues performed integrated genomic analyses of oral squamous cell carcinomas (OSCC), a particularly lethal, poorly characterized HNSCC sub-type. The Notch pathway was deregulated in 66% of OSCCs, and inactivation of NOTCH1 was shown to drive OSCC growth. Common inactivating mutations of FAT1 and CASP8 were also identified. Together, these findings provide insight into the etiology of HNSCC and identify potential therapeutic targets.

about
Dahlman and colleagues identified a BRAFL597R mutation in an aggressive BRAFV600E-negative melanoma, and found that as many as 8% of melanomas classified clinically as “BRAF wild type” may actually harbor other less common BRAF exon 15 mutations. Importantly, these mutants led to increased MEK/ERK signaling that was readily suppressed by MEK inhibitors, suggesting that patients with these less common BRAF mutations may also benefit from MEK inhibitor therapy. Indeed, one such patient with metastatic melanoma enrolled in a phase I trial of an allosteric MEK inhibitor experienced a sustained partial response, indicating that expanded BRAF mutational testing may benefit additional patients.

Genome relationships of chickpea with closely related legume species. Homologous relationship of chickpea genome with four legume spe-cies, that is,Medicago truncatula(a), soybean (b),Lotus japonicus(c) and cowpea (d), has been shown by comparing sequence data of 1064 mappedmarkers of chickpea with genome sequence ofMedicago(Mt 3.5),L. japonicus(Lj 2.5 pseudomolecules), soybean (Glyma1 genome assembly) andcowpea genetic map (Mucheroet al., 2009). Maximum similarity was observed withMedicago(1558), followed with soybean genome (1798),Lotus(438) and least with cowpea (55). The percentage of matches in each species is in congruence with their phylogenetic distances.

Human reference genomes, represented by circles; the arcs inside each circle symbolize highly related sequenced genomes (i.e., individuals from the same family or population). The colorful abstract segments on each arc show common and rare structural variation events among individual genomes. The CommonLAW package presented in this issue introduces novel combinatorial formulations and algorithms for structural variation discovery among a number of sequenced donor genomes, with the help of a complete reference genome. CommonLAW significantly reduces the false positive rate in detecting structural variation events when compared with conventional methods.

Circle of Cancer. This picture of a tumor genome is at the heart of the personalized cancer treatment described by Roychowdhury et al. in this issue. By quickly sequencing normal and tumor DNA and RNA (in 3 to 4 weeks) from patients with colorectal and prostate cancer, the authors could summarize the key genetic defects of the tumor (blue lines, intrachromosomal rearrangements; yellow lines, inversions; orange lines, interchromosomal rearrangements). A board of experts then recommended suitable therapy, tailored for the specific mutations identified.

Scanning Fetal DNA. During pregnancy, a fetus releases its DNA as short fragments into the blood of its mother. In this issue, Lo et al. report that by sequencing billions of DNA molecules from the plasma of a pregnant woman they were able to assemble the full genome of the fetus prenatally and noninvasively and identify a mutation in the fetal DNA for the inherited blood disease β-thalassemia. The outermost ring of this week’s cover image depicts human chromosomes arranged in a circle. The green, red, and blue rings show the sequence composition (GC content) and the extent of sequencing for total (mainly maternally-derived) DNA and fetal-specific DNA in maternal plasma, respectively.

about
The development of modern communication and information technologies like the Internet and globalization have not only changed access and spread of the available knowledge but also the speed of collecting. The author examines collections of knowledge such as archives, encyclopedias, data collections, and libraries that make knowledge accessible worldwide. Who is collecting the world’s knowledge? How is it structured and designed? Who determines the access of knowledge? Designers and researchers from different fields have set standards for the classification and design of complex data collections and thus exerted an enormous influence on how knowledge is communicated. This facilitates knowledge transfer, but it also increases the danger of manipulation. Along with these aspects, the book also explores the possibilities of “universal design” and presents new approaches to visualizing complex information.

about
A circular representation of small RNA alignment frequency for 21-nt and 24-nt small RNAs along the length of each of the 12 nuclear Oryza sativa chromosomes (green), starting with the first chromosome at 12 o’clock. The yellow and orange consecutive rings represent degenerate alignments of 21-nt and 24-nt small RNAs, respectively, to the corresponding chromosomes. Small RNA alignments are nonuniform with hot spots of 24-nt sequences aligning to the heterochromatic regions, including most centromeres and some clusters of ribosomal RNA genes. The fractal trees conceptually represent our use of sequence-based hierarchical clustering and graph theory algorithms to identify novel microRNA families in Pinus contorta. (Cover illustration by Ryan Morin using Circos, fractal image created by Maia.)

about
Rearrangement history of the mammalian X chromosome in human, mouse, and rat lineages. The arrangement of the 16 human-mouse-rat large-scale orthologous segments (each containing at least 300,000 nucleotides) located on the X chromosome is shown for the human, mouse, and rat genomes. Possible arrangements of the last common ancestor of mouse and rat ("Mouse-Rat Ancestor") were computed from these. The computations prove that the arrangement shown is the only one that minimizes the number of inversions of these segments on the paths to it from human, mouse, and rat. A possible order of those inversions is illustrated, but the actual order will not be determined until future studies allow us to add more species to this tree. Previous studies found that the arrangement of markers in the human X chromosome was unchanged since before the "Human-Mouse-Rat Ancestor," and our use of outgroup data from dog, cat, and cow is consistent with this (although we cannot rule out the possibility that the second segment from the right in human was inverted on the human lineage). The drawings of creatures at the ancestral nodes are probably similar to the last common ancestors of the species indicated at the nodes. (For details, see Bourque et al., pp.507–516. ). The cover uses my photo of Alex, the world's most popular rat.
