Copy number variations of colorectal cancer by whole exome sequencing data

Colorectal cancer (CRC) is the third most common cancer and the fourth leading cause of cancer death worldwide. About 85% of the cases of CRC are known to have chromosomal instability, an allelic imbalance at several chromosomal loci, and chromosome amplification and translocation. The aim of this study is to determine the recurrent copy number variant (CNV) regions present in stage II of CRC through whole exome sequencing, a rapidly developing targeted next-generation sequencing (NGS) technology that provides an accurate alternative approach for accessing genomic variations. 42 normal-tumor paired samples were sequenced by Illumina Genome Analyzer. Data was analyzed with Varscan2 and segmentation was performed with R package R-GADA. Summary of the segments across all samples was performed and the result was overlapped with DEG data of the same samples from a previous study in the group1. Major and more recurrent segments of CNV were: gain of chromosome 7pq(13%), 13q(31%) and 20q(75%) and loss of 8p(25%), 17p(23%), and 18pq(27%). This results are coincident with the known literature of CNV in CRC or other cancers, but our methodology should be validated by array comparative genomic hybridisation (aCGH) profiling, which is currently the gold standard for genetic diagnosis of CNV.

Copy&Paste façanes procedurals per skylineEngine

L’objectiu d’aquest projecte és el desenvolupament d’una eina d’alt nivell pel modelatged’edificis procedurals que permeti copiar i enganxar parts arbitràries d’un edifici en un altre.Els edificis procedurals es basen en l’execució iterativa d’un conjunt de regles, que es podenrepresentar per un graf d’operacions. Per tant, l’operació de copiar i enganxar es centra enla reescriptura dels grafs de regles amb l’objectiu de modificar els edificis per tal de duraquesta tasca. Donat que es treballa sobre la plataforma de recerca anomenada skylineEngine,que s’executa sobre el programari Houdini 3D, l’aplicació també estarà implementada a sobred’aquesta plataforma

A high-copy T7 Escherichia coli expression vector for the production of recombinant proteins with a minimal N-terminal His-tagged fusion peptide

We report here the construction of a vector derived from pET3-His and pRSET plasmids for the expression and purification of recombinant proteins in Escherichia coli based on T7 phage RNA polymerase. The resulting pAE plasmid combined the advantages of both vectors: small size (pRSET), expression of a short 6XHis tag at N-terminus (pET3-His) and a high copy number of plasmid (pRSET). The small size of the vector (2.8 kb) and the high copy number/cell (200-250 copies) facilitate the subcloning and sequencing procedures when compared to the pET system (pET3-His, 4.6 kb and 40-50 copies) and also result in high level expression of recombinant proteins (20 mg purified protein/liter of culture). In addition, the vector pAE enables the expression of a fusion protein with a minimal amino-terminal hexa-histidine affinity tag (a tag of 9 amino acids using XhoI restriction enzyme for the 5'cloning site) as in the case of pET3-His plasmid and in contrast to proteins expressed by pRSET plasmids (a tag of 36 amino acids using BamHI restriction enzyme for the 5'cloning site). Thus, although proteins expressed by pRSET plasmids also have a hexa-histidine tag, the fusion peptide is much longer and may represent a problem for some recombinant proteins.

Copy of poster advertising “Grand Buffalo Hunt at Niagara Falls” with Bill Hickok, August, 1872

James Butler Hickok (1837-1876), also known as “Wild Bill” Hickok, was an American gun-fighter, scout and spy. He was involved in altercations with others while working for the famous express company Russell, Majors and Waddell (in 1861), and later while working as a wagon master, scout, and spy for the Union forces during the Civil War. These altercations resulted in the deaths of 4 people, but Hickok was acquitted in all cases. An embellished article written about him in Harper’s magazine helped contribute to his reputation as a western hero. He served as a deputy U.S. marshal and sheriff in Kansas in the late 1860’s, helping to bring law and order to a previously lawless area. He gambled considerably, and during a card game on August 2, 1876, was shot and killed. The cards he was holding (two aces, two eights, and a jack) became known as the "dead man's hand."

Copy of page 141 of Confederation by Joseph Pope annotated by John A. Macdonald, 1867

Joseph Pope was born in Charlottetown, Prince Edward Island in 1854. He was the private secretary to Sir John A. Macdonald from 1882-1891. He worked as the assistant clerk to the Privy Council and undersecretary of state for Canada from 1896-1909. He was appointed a Companion of the Order of St. Michael and St. George in 1901. He was later knighted as a Knight Commander of the same order. Joseph Pope was the first permanent head of the Department of External Affairs (now Foreign Affairs and Internal Trade) 1909-1925. He was an advisor to Prime Ministers from Macdonald to King. He died in Ottawa, in 1926. As well as Confederation, Pope also penned: Memoirs of Sir John A. Macdonald : A Chronicle of the First Prime Minister of the Dominion; The Day of Sir John Macdonald; Jacques Cartier, his life and voyages; Traditions and Sir John A. MacDonald vindicated : a review of the Right Honourable Sir Richard Cartwright's reminiscences as well as other books Pope’s son, Maurice Arthur Pope wrote a book about Joseph entitled Public Servant: the Memoirs of Sir Joseph Pope”.
