Glossary
AmpliconA piece of DNA or RNA that is the source and/or product of amplification or replication events. It can be formed artificially or naturally.
Amplicon ArchitectA computational approach for mapping the fine structure of amplicons in cancer cell lines.
Asp-Glu-AlaRefers to a sequence of amino acids, the building blocks of protein, arranged in a specific order: aspartic acid (Asp), glutamic acid (Glu), and alanine (Ala).
ATAC-seq and MNase-seqTechniques for studying chromatin accessibility and nucleosome positioning.
ATPaseAn enzyme found in cells that plays a crucial role in energy transfer. It helps break down a molecule called ATP (adenosine triphosphate) to release energy that cells need to function.
Breakage Fusion Bridge cycles (BFBs)A cycle of events in which chromosomes break and fuse repeatedly.
Cancer Dependency MapA strategic collaboration with the Broad Institute (Boston, MA, USA) and other institutes that leverages the expertise and infrastructure available at each institution to catalyse a new wave of precision cancer medicines. https://depmap.org/portal/
Cargo geneAny gene (or genes) harboured on the sequence of an extrachromosomal DNA (ecDNA) element.
CentromereAppears as a constricted region of a chromosome and plays a key role in helping the cell divide up its DNA during division (mitosis and meiosis).
Chromatin accessibilityThe extent to which proteins are able to interact with chromatinised DNA, which is regulated through nucleosome occupancy and other factors occluding access to DNA.
Chromatin Conformation CaptureTechniques for studying the three-dimensional structure of chromatin.
ChromosomesThread-like structures in the nucleus of cells that contain genes and genetic information.
ChromothripsisA catastrophic event involving numerous structural rearrangements of a chromosome.
Co-AmplificationRefers to a situation where multiple genes are amplified or multiplied in a cell simultaneously. This process can occur in cancer cells and is often associated with the overproduction of certain proteins that promote cancer growth or progression.
Core regulatory enhancer elementsSpecific DNA sequences within the genome that play a pivotal role in governing gene expression. These enhancers are stretches of DNA that can augment the transcription of genes, impacting the timing and intensity of a particular gene's expression.
CRISPR-Cas9Derived from the bacterial immune defence system, stands for clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9. This technique enables precise editing of DNA sequences and has been adapted for various genome editing applications.
CRISPR-CATCHDeveloped by the Chang lab is a method that enhances the isolation of megabase-sized extrachromosomal DNA (ecDNA) from cancer cells and patient tissue, aiding in research related to cancer genomics.
CytogeneticsThe study of chromosomes and their relationship to human diseases.
DEAD box helicasesDespite their name are not linked to cell death. They constitute a family of proteins fundamental to cellular functions, especially in RNA metabolism, regulating RNA dynamics within cells.
Double MinutesSmall fragments of extrachromosomal DNA (ecDNA), which have been observed in a large number of human tumors including breast, lung, ovary, colon, and most notably, neuroblastoma.
EGFR (epidermal growth factor receptor)A protein on cells that helps them grow. A mutation in the gene for EGFR can make it grow too much, which can cause cancer.
EpigeneticsThe study of changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence.
Extrachromosomal DNA (ecDNA)DNA that exists outside the normal chromosomes in a cell that encodes oncogenes. ecDNAs lack centromeres and telomeres and must rely on unknown mechanisms to ensure transmission into daughter cells during cell division.
FAM49AA protein, also known as STRAP, that is involved in diverse cellular processes, including signalling pathways related to cell growth, proliferation, and survival.
Focal amplificationDescribes a specific increase in the copy number of a particular DNA segment or region within a chromosome, focusing on a localised area instead of amplifying the entire chromosome.
Genetic moietiesRefers to the various components or parts that constitute an organism's genetic material.
GenomesThe complete collection of genes or genetic material present in a cell or organism.
Histone MarksChemical alterations on histone proteins that can influence gene regulation.
Homogeneously staining regions (HSRs)Sections on chromosomes that display a uniformly stained appearance when observed under a microscope. These regions are significant as they often indicate genetic irregularities such as additional copies of genes or gene sequences.
Intratumoral Genetic HeterogeneityThe genetic variation present within a tumour.
MeiosisA cellular process in which a single cell divides twice to produce four cells, each containing half the original amount of genetic information.
MetabolomicsA field of biology studying the comprehensive analysis of small molecules, known as metabolites, within cells, tissues, or biological systems.
MicronucleiSmall nuclear structures present in the cytoplasm containing damaged DNA fragments that were not incorporated into the main nucleus after mitosis.
MitosisA cellular process wherein replicated genetic information in a single cell divides into two identical nuclei.
mRNAAbbreviation for messenger RNA. This type of RNA (ribonucleic acid) molecule plays a vital role in gene expression by carrying genetic information from the cell's nucleus DNA to the ribosomes in the cytoplasm, where proteins are produced.
mTORShort for the mechanistic target of rapamycin, a protein kinase that regulates cellular processes in response to various signals, such as nutrient availability, energy levels, and stress. It acts as a central regulator of cell growth, proliferation, metabolism, and survival.
MTORC1The abbreviation for mechanistic target of rapamycin complex 1, primarily regulating processes related to cell growth and metabolism.
Mutational SignatureThe outcome of a mutagenic process involving some form of DNA damage, subsequently influenced by DNA repair and/or replicative machinery.
MYCRefers to a family of proto-oncogenes encoding transcription factors that regulate the expression of numerous genes. Overexpression or dysregulation of MYC proteins is often associated with cancer, leading to uncontrolled cell growth and tumour development.
MYCNA gene that encodes the protein N-Myc and is a member of the MYC family of proto-oncogenes, implicated in tumour formation and progression.
NeuroblastomaPrimarily a childhood cancer that arises from immature nerve cells, commonly found in the adrenal glands but can occur in various areas like the abdomen, chest, neck, or near the spine.
Neuroblastoma Amplified Sequence (NBAS)Refers to a gene associated with neuroblastoma, a childhood cancer originating from immature nerve cells.
Nucleosomes" Chromosomal structural units consisting of DNA wrapped around histone proteins."
OncogenesGenes with the potential to cause cancer by promoting cell growth and division.
Passenger GeneA gene or genetic alteration observed alongside a primary genetic change but does not significantly contribute to disease development or progression.
PhasingThe process of deducing haplotype information of a sequence from genomic data.
Precision OncologyCustomising cancer treatments for individual patients based on their specific genetic characteristics.
ProteomicsThe comprehensive study of proteins in a biological system.
Structural VariantsLarge genomic alterations encompassing deletions, duplications, insertions, inversions, and translocations that describe different combinations of DNA gains, losses, or rearrangements.
TCA CycleTCA (tricarboxylic acid) cycle, also known as the Krebs cycle or citric acid cycle, is a crucial part of cellular respiration and is pivotal in producing ATP, the cell's energy currency.
TelomereA region of repetitive DNA sequences at the end of a chromosome. Telomeres protect the ends of chromosomes from becoming frayed or tangled. With each cell division, telomeres shorten until the cell can no longer divide successfully, leading to cell death.
