Confidence and Uncertainty - A multilabel AI-based model for evaluating protein expression in testis

In a study led by researchers in the HPA and at Brunel University London, a novel method for automated annotation of immunohistochemistry images was developed for annotating cell type-specific protein expression of 8 different cell types in human testis. The work comprised 7848 images (corresponding to 2794 proteins) and the image classifier also provided a novel uncertainty metrics (called DeepHistoClass), for identification of manual annotation errors. The workflow can be implemented for other tissues or utilized in large-scale protein mapping efforts for sourcing high-quality data...Read more


The in situ expression of missing proteins in spermatogenesis

Spermatogenesis is the process where sperm are made, and it involves thousands of genes and proteins that are activated and repressed. The function of a large proportion of these genes and proteins remains unknown and testis harbors many "missing proteins" (MPs)...Read more


Profiling cancer testis antigens

In a recent publication in JCI Insight researchers from the Human Protein Atlas have described the expression of the currently known cancer-testis antigens (CTAs) in non-small cell lung cancer, and have added 50 new CTAs to this list.

Lung cancer is the most common cause of cancer related death in Sweden and worldwide. Most patient present with advanced disease and have a short life expectancy despite modern therapy.

Analysis of 32 human organs and tissues

In the Human Protein Atlas, there are 32 human organs and tissues analyzed. 2489 of the genes have significantly higher expression in one tissue compared to all other tissue types. Analysis show that testis is the organ with the largest number of tissue-enriched genes, with 1057 genes classified as testis enriched. The specific events and alterations of cell structure during spermatogenesis, and the fact that sperm has the ability to survive outside the male body may explain why testis has the largest number of enriched genes.

The organ with the second highest number of enriched genes is the brain with 381 enriched genes...Read more
