7th HUPO World Congress

2 August 2008 | By

The 7th World Congress of the Human Proteome Organisation, HUPO, will be held at the RAI Congress Centre in Amsterdam, the Netherlands, from 16-20 August 2008.

Accessing stem cells via proteomics

2 August 2008 | By

Stem cells have two important characteristics that distinguish them from other cells: the ability to self-renew through cell division for a prolonged period, and to differentiate into multiple cells with specialised functions. The power of stem cells for tissue development, regeneration and renewal has been well known to embryologists for…

MALDI FT-ICR MS platform for proteomics: Rationale for an offline approach and optimised implementation

19 July 2008 | By

MALDI FT-ICR MS platform for proteomics: Rationale for an offline approach and optimised implementation A number of sophisticated approaches have been developed to study the structure and function of genes, including the whole-scale sequencing of entire organisms[1], global transcriptional profiling[2], and forward genetic studies[3]. However, these techniques are ultimately limited…

Platform technology for routine three dimensional cell culture

19 June 2008 | By Dr Stefan Przyborski, Chief Scientific Officer, ReInnervate Ltd, School of Biological and Biomedical Science, Durham University

Cell culture assays play an important role during the first stages of pharmaceutical development. The design of such in vitro models is significant and data resulting from such tests directly influences the progression of compound development. Therefore it is becoming progressively more important to design cell culture assays that are…

MicroRNAs for high-throughput functional analysis

19 June 2008 | By

MicroRNAs (miRNAs) are a class of small non-coding RNA molecules, which are potent post-transcriptional gene expression regulators. They have been shown to participate in the regulation of numerous cellular processes, the list of which is still growing. miRNAs affect numerous targets that can be determined by direct experiments or predicted…

Assessing the current proteomics field

7 April 2008 | By

There has been much interest in the promise of proteomics to deliver biomarkers with utility for disease diagnosis and classification, and for assessing therapeutic efficacy and monitoring disease progression. However recently, particularly in the past year, expressions of concern have started to emerge regarding the paucity of protein biomarkers that…

Genomics for the new biomedicine

7 April 2008 | By

One of the most profound advances in biology and medicine has been the sequencing of entire genomes, including the human genome. The end product was the availability of the complete genetic blue print of organisms of importance to medicine and biotechnology. This changed how we conducted science. Cloning individual genes…

Mass spectrometry based proteomics: trends in tools and strategies

7 April 2008 | By

Recent years have seen great upward leaps in the development of mass spectrometry applied to the field of proteomics. Today it is possible to take a complex biological sample such as organelles, cells, tissue or a biofluid, perturbed or stimulated in some way, and identify and quantitate up to several…

Night on Highway 128

19 March 2008 | By

Most people in molecular biology today are not old enough to remember pre-PCR. But try to do your job without it and you will see what a difference that simple little technique has made. ‘Polymerase Chain Reaction’ is now a word in Merriam Webster’s Collegiate Dictionary and if you put…

The role of chemokines in type 1 diabetes: as assessed by RT-PCR

19 March 2008 | By

Type 1 diabetes is an autoimmune disease, characterised by immune infiltration into the islets of Langerhans, resulting in the destruction of insulin producing b-cells. Over recent years, evidence has been collected on the important role of chemokines in the recruitment of immune cells leading to the pathology of this disease.…

Antibody-based proteomics to study cellular signalling networks

19 March 2008 | By

The complexity of drug discovery faces many challenges; principally, the failure of drug candidates during the development process as a result of adverse effects or lack of efficacy. A key reason for this high attrition rate is that we are only just beginning to understand the complexity of the response(s)…

Personalised medicine: are we ready for the revolution?

19 March 2008 | By

The impact of biomarker technology and biomarker strategies in pharmaceutical development is still in its infancy; but the impact is already proving significant. Biomarker strategy forms the basis for personalised medicine, the industry/regulatory focus centres on improving the success rate and reducing the high attrition rate often encountered in early…

Size does matter: macro ncRNAs and the regulation of imprinted gene clusters

23 January 2008 | By

The availability of the human and the mouse sequence has allowed genome-wide analysis of transcription to produce 'transcriptomes' that list all RNA transcripts in specific cell types or tissues. These studies have identified a surprisingly large number of ncRNAs that were not recognised by gene annotation programs applied to the…
