THE HUMAN PROTEIN ATLAS BLOG
As part of the release Pathology Atlas release, the Human Protein Atlas will each week present a brief and informative summary highlighting genes with prognostic association in different cancer forms. This week, we will focus on Lung cancer one of the deadliest cancers in the world today.
Lung cancer patients have a poor outcome with a 5-year survival rate of 13.6% in men and 19.4% in women. Late diagnosis and lack of effective treatments are considered to contribute to poor prognosis. Smoking is the leading risk factor and is responsible for 70-90% of the lung cancer cases. Lung cancer can be divided into small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC)...Read more
The importance of mapping the human cell has become recognized as one of the key challenges in modern biology. Image-based assays offer a data-rich medium of studying cells and their proteins in situ. As such, several large-scale initiatives for studying cellular biology using image-based assays have been founded in recent years...Read more
Over the last couple of months, you have hade the pleasure to see Image of the week here on the blog, where an image we find particularly interesting has been shown and discussed. Now that our Cell Atlas is out, you can browse images of your favorite protein directly in our database! In addition to all the images we have added, there are also new "Human Cell" chapters, which provide a knowledge-based analysis of the human cellular proteomes and an entry into the Human Protein Atlas from different perspectives...Read more
In less than one month from now, we will release a new version of our database, HPA16! The biggest news is the introduction of a brand new Cell Atlas. It will be an image-based atlas over the subcellular distribution of the human proteome.
– Cells are the machinery of life. Much of the bustling activity in the human cell results from proteins performing specific tasks in designated compartments, the organelles. The Cell Atlas that we are creating will be image-based and describe the subcellular distribution of the human proteome, says Emma Lundberg, Director of the Cell Atlas...Read more
In a recent study in Journal of Proteome Research by Human Protein Atlas-researchers a new reactive epitope of a prostate specific protein, particularly reactive in the late stages of prostate cancer is identified.
According to WHO, prostate cancer is the second most incident cancer in men and the fifth leading cause of death in men worldwide, and there is a demand for novel targets and approaches to diagnose and treat this cancer type. Five-year survival is reached by almost 100% of patients if the disease is still at a local and regional stage; however, the survival rate drops down to 30% in the case of aggressive form with distant metastasis and relapse after treatment...Read more
Several previous reports have concluded that RNA levels cannot be used to predict protein levels. However, in a new study from KTH Royal Institute of Technology, published in the journal Molecular Systems Biology scientists from the Human Protein Atlas show that protein levels can be predicted from RNA levels if a gene-specific RNA-to-protein factor is used.
The human genome consists of DNA, a molecule that contains the instructions needed to build and maintain cells. For the instructions to be carried out, DNA must be read and transcribed into RNA transcripts that can be used to produce protein. The transcriptome is a collection of all the transcripts present in a cell...Read more
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
In a recent number of Nature Reviews, Human Protein Atlas researchers Mathias Uhlén and Adil Mardinoglu discuss a study by E.G. Williams and co workers in Science where five complementary -omics datasets across various environmental states (including genomics, transcriptomics, proteomics, metabolomics and phenomics) using the liver as a platform for multiomics analysis are integrated...Read more
Today we meet yet another researcher within the Human Protein Atlas project, Jochen Schwenk, Associate Professor for Translational Proteomics at KTH - Royal Institute of Technology in Stockholm, Sweden. He is Director of the Biobank Profiling facility at the Science for Life Laboratory and a Principal Investigator within the Human Protein Atlas and the KTH Center for Applied Proteomics.
– I have a PhD in Biochemistry from the University of Tübingen in Germany, and when I saw presentations from the Human Protein Atlas Director Mathias Uhlén at a few meetings I thought that this would be an exiting project to work with after my PhD thesis, Jochen Schwenk says...Read more
A new study by researchers within the Human Protein Atlas project was just published in Autoimmunity .
The researchers analyzed the presence of autoantibodies in patients with vaccine-associated narcolepsy. In an initial screening, IgG reactivity to approximately 10000 protein fragments was investigated, revealing a large heterogeneity in which autoantibodies that are present in different individuals.
Anna Häggmark is the first author of the paper...Read more
Time has come for the second interview with a researcher within the Human Protein Atlas project. Today we meet Cecilia Lindskog, site director of the Tissue Atlas.
– I have a Master of Science in Biomedicine and a Doctor of Philosophy in pathology from the Faculty of Medicine, Uppsala University. I joined the Human Protein Atlas project in 2006, and also have industry experience in the biotechnology industry, from Oncomark Ltd, Dublin, Ireland.
Cecilia Lindskog´s main research interests have always been understanding the biology and functions of different organs, and the underlying mechanisms leading to cancer and other diseases...Read more
Majority of differentially expressed genes are down-regulated during malignant transformation in a four-stage model
From primary to malignant - what changes? Bridging transcriptomics and proteomics to reveal the molecular changes during malignant transformation in a four-step cancer cell line model
In order to find out more about the changes that occur when a primary cell is transformed into an aggressive cancer cell, integration of biological information has proven to be successful. By bridging transcriptomics and antibody based proteomics data we showed how the major changes during malignant transformation could be scrutinized...Read more
