Investigating brain-enriched proteins

CSF_picture.jpg

In a recent study published in Proteomics Clinical Applications researchers from the Human Protein Atlas have profiled 280 brain-enriched proteins in cerebrospinal fluid from patients with Alzheimer┬┤s disease, Parkinson┬┤s disease and dementia with Lewy bodies. This study is part of a larger effort aiming to expand the knowledge of brain-enriched proteins in human cerebrospinal fluid and to provide novel insight into the relation between such proteins and different neurodegenerative diseases.

The researchers report a multiplexed protein profiling using an affinity-based proteomics approach to generate cerebrospinal fluid profiles of brain-enriched proteins...Read more


Citrate synthase and mitochondrial disease

574_A12_1_blue_red_green.jpg

Mitochondria are responsible for the energy production in our cells. The most interesting thing about mitochondria is that they have their own DNA which means some proteins in the mitochondria come from nuclear DNA and some from mitochondrial DNA. In a previous image of the week we highlighted TOMM5, a protein responsible for transport of nuclear encoded mitochondrial proteins into the mitochondria.

In this week's image of the week we take a look at citrate synthase (CS), a nuclear encoded mitochondrial protein that is a key enzyme for the citric acid cycle of the cell (TCA cycle), also known as the Krebs cycle...Read more


Mad about Mitochondria

This week, it is Mitochondrial Disease Awareness Week. Therefore we would like to take the opportunity to talk about the mitochondrial proteome, the work we do within this field, and you will even get to meet one of our researchers, involved in this work.

The mitochondria are distributed throughout the cytoplasm of the cell, each organelle enclosed by a double membrane, the inner one forming the characteristic folds known as cristae. Mitochondria are essential for producing the cell´s need of ATP through cellular respiration, but have also been shown to participate in many other cellular functions, including apoptosis, calcium storage and cellular signaling...Read more


Image of the week - Lysosomes

Welcome to another HPA image of the week! This week we take a look at another member of the vesicle family, the lysosomes.

In a way, lysosomes can be thought of as the recycling plants of your cells. Lysosomes are small membrane bound vesicular organelles that degrade biomolecules within your cells so that the materials in these molecules can be recycled and used for other cellular processes. Often these biomolecules come from vesicles known as endosomes that bring in materials from outside your cells, however lysosomes are also known to degrade other organelles, and products from within the cell...Read more


Novel assay concept developed

In an article in a special edition of Proteomics, on protein arrays researchers from the Human Protein Atlas describe the development of a novel assay concept, which combines the flexibility and multiplexing capacity of single-binder assays and the specificity and sensitivity aspects of dual-binder assays. They developed a multiplexed dual-binder assay procedure, which is based on a sequential protein capture.

– This assay is a great addition to the antibody-array toolbox of the Biobank Profiling Group, both to support related assay development activities and for biomarker discovery applications, says Burcu Ayoglu, first author of the study...Read more
