HeLa cell - the "immortal cell"

A HeLa cell (also Hela or hela cell) is a cell type in an immortal cell line used in scientific research. It is one of the oldest and most commonly used human cell lines.[1] The line was derived from cervical cancer cells taken from Henrietta Lacks, a patient who eventually died of her cancer on October 4, 1951. The cell line was found to be remarkably durable and prolific as illustrated by its contamination of many other cell lines used in research.[2][3]

Poster: Sparse Instrumental Variables (SPIV) for Genome-Wide Studies

Felix Agakov, Paul McKeigue, Jon Krohn, Amos Storkey

M74

This paper describes a probabilistic framework for studying associations between multiple genotypes, biomarkers, and phenotypic traits in the presence of noise and unobserved confounders for large genetic studies. The framework builds on sparse linear methods developed for regression and modified here for inferring causal structures of richer networks with latent variables. The method is motivated by the use of genotypes as ``instruments'' to infer causal associations between phenotypic biomarkers and outcomes, without making the common restrictive assumptions of instrumental variable methods. The method may be used for an effective screening of potentially interesting genotype phenotype and biomarker-phenotype associations in genome-wide studies, which may have important implications for validating biomarkers as possible proxy endpoints for early stage clinical trials. Where the biomarkers are gene transcripts, the method can be used for fine mapping of quantitative trait loci (QTLs) detected in genetic linkage studies. The method is applied for examining effects of gene transcript levels in the liver on plasma HDL cholesterol levels for a sample of sequenced mice from a heterogeneous stock, with $\sim 10^5$ genetic instruments and $\sim 47 \times 10^3$ gene transcripts.

Scale-free network

A scale-free network is a network whose degree distribution follows a power law, at least asymptotically. That is, the fraction P(k) of nodes in the network having k connections to other nodes goes for large values of k as

P(k) \ \sim \ ck^\boldsymbol{-\gamma}

where c is a constant and γ is a constant whose value is typically in the range 2 < γ < 3, although occasionally it may lie outside these bounds. Scale-free networks are noteworthy because many empirically observed networks appear to be scale-free, including the world wide web, the Internet, citation networks, and some social networks. http://en.wikipedia.org/wiki/Scale-free_network

Random vs Scale-free networks
Random network (a) and scale-free network (b). In the scale-free network, the larger hubs are highlighted.

3rd generation transcriptomics - CAGE

Monday Noon Seminar: Dr. Piero Carninci, RIKEN Yokohama Institute
12:00 PM-1:00 PM (Lecture Theatre)

3rd generation transcriptomics - CAGE

Breakthroughs in science depend on the development of novel technologies to solve outstanding biological problems. We have previously developed key technologies including the cap-trapper to comprehensively clone full-length cDNAs and the cap-analysis gene expression (CAGE). The mission of the Functional Genomics Technology Team is to develop novel original approaches to comprehensively study genes, their products and their interactions. The approaches should address biological questions that cannot be addressed with technologies that are the state of the art today. In contrast with classic approaches considering one gene at the time, our mission is to develop approaches that aim at targeting biological problem as systems. This requires to comprehensively analyzing various biological aspects.
The members of the laboratory are engaged in the development of original approaches and to design, propose and realize original genomics technologies and apply these to challenging biological problems. These include the discovery, validation and analysis of novel classes of non-coding RNAs; establishing single-cell CAGE methods and its application to reduced biological samples; and data mining, with particular interest at identifying biological patterns and rules, including genome-wise analysis of novel classes of RNAs and their network. To address these genomics approaches for samples derived from living cells in their biological context, particular emphasis consists in the miniaturization of these technologies, to analyze systematically the biology of few or single isolated cells, such as the characterization of the molecular networks of individual neurons, included in a larger cellular networks. Going beyond simple expression profiling, the ultimate mission is to understand the complex relationships between gene expression regulation, the non-coding RNA world, the epigenome and the biological output.

http://fantom.gsc.riken.jp

The FANTOM consortium is an international collaborative research project initiated and organized by the RIKEN Omics Science Center. In earlier FANTOM efforts we cloned and annotated 103,000 full-length cDNAs from mouse and distributed them to researchers throughout the world. FANTOM1-3 focused on identifying the transcribed components of mammalian cells. This work improved estimates of the total number of genes and their alternative transcript isoforms in both human and mouse, expanded gene families, and revealed that a large fraction of the transcriptome is non-coding. In addition, with the development of Cap Analysis of Gene Expression (CAGE) FANTOM3 could map a large fraction of transcription start sites and revise our models of promoter structure. This updated web resource provides the previous FANTOM results mapped to current genome builds and presents the results of FANTOM4.

Mass spectrometry

http://www.21stcenturybio.com/mass_spec_analytical/ms_cid.shtml

One of the most powerful tools available to the mass spectrometrist is MS/MS. Whereas fragmentation is virtually absent in electrospray mass spectrometry, it can be deliberately induced by MS/MS techniques. Tandem MS employs collision-induced dissociation (CID) to fragment a precursor ion.

Similarly, various amino acid modifications can be determined due to the gentle nature of ESI (versus MALDI, which tends to remove some modifications, such as phosphates). These include phosphorylation, glycosylation, acylation, nitronation, and many others.

Ionization source Advantages Disadvantages
Matrix associated desorption Ionization

Life Built With Toxic Chemical: First Known Microbe on Earth Able to Thrive and Reproduce Using Arsenic

http://www.sciencedaily.com/releases/2010/12/101202140622.htm

Too bad they haven't named it yet, but apparently, this organism uses arsenic (chemically similar to phosphorus) instead of phosphorous in it's DNA/RNA, etc.  It was discovered in Mono Lake in California.

CGH, Chromosomal Microarray Analysis (CMA), Copy number variation (CNV)

Comparative genomic hybridization (CGH) or Chromosomal Microarray Analysis (CMA) is a molecular-cytogenetic method for the analysis of copy number changes (gains/losses) in the DNA content of a given subject's DNA and often in tumor cells.

CGH will detect only unbalanced chromosomal changes. Structural chromosome aberrations such as balanced reciprocal translocations or inversions cannot be detected, as they do not change the copy number.

- Many coefficients were proposed for measuring the degree of LD, but they provide only a static view of the current LD structure. Generative models (GMs) were proposed to go beyond these measures, giving not only a description of the actual LD structure but also a tool to help understanding the process that generated such structure.
- method is based on learning optimal BN structures (weighted) from haplotype data, extracting equivalence structure classes (PDAGs) and using them to model LD.

- These plots provide a nice visualization of how single nucleotide polymorphisms (SNPs) travel together in human subpopulations and samples due to linkage disequilibrium (LD).

Peripheral blood - circulating blood,

Peripheral blood is the flowing, circulating blood of the body. It is composed of erythrocytes, leukocytes and thrombocytes. These blood cells are suspended in blood plasma, through which the blood cells are circulated through the body. Peripheral blood is different from the blood whose circulation is enclosed within the liver, spleen, bone marrow and the lymphatic system. These areas contain their own specialized blood.

Lymph nodes also have clinical significance. They become inflamed or enlarged in various conditions, which may range from trivial, such as a throat infection, to life-threatening such as cancers. In the latter, the condition of lymph nodes is so significant that it is used for cancer staging, which decides the treatment to be employed, and for determining the prognosis.

Lymphoma is a cancer in the lymphatic of the immune system and presents as a solid tumor of lymphoid cells. It is treatable with chemotherapy, and in some cases radiotherapy and/or bone marrow transplantation, and can be curable depending on the histology, type, and stage of the disease.[1]

Thomas Hodgkin published the first description of lymphoma in 1832, specifically of the form named after him, Hodgkin's lymphoma.[2]

Cat-loving mice
http://en.wikipedia.org/wiki/Toxoplasma_gondii
T. gondii infections have the ability to change the behavior of rats and mice, making them drawn to, rather than fearful of, the scent of cats. This effect is advantageous to the parasite, which will be able to sexually reproduce if its host is eaten by a cat.[11] The infection is highly precise, as it does not affect a rat's other fears such as the fear of open spaces or of unfamiliar smelling food.

Studies have also shown behavioral changes in humans, including slower reaction times and a sixfold increased risk of traffic accidents among infected males[12], as well as links to schizophrenia including hallucinations and reckless behavior[13]. A study of 191 young women in 1999 reported higher intelligence and lower guilt proneness in Toxoplasma-positive subjects[14].

Processing: A programming language for visual designers and artists

http://www.processing.org/
http://processing.org/learning/gettingstarted/

Processing is an open source programming language and environment for people who want to create images, animations, and interactions. Initially developed to serve as a software sketchbook and to teach fundamentals of computer programming within a visual context, Processing also has evolved into a tool for generating finished professional work. Today, there are tens of thousands of students, artists, designers, researchers, and hobbyists who use Processing for learning, prototyping, and production.
