The plots are interactive in that they filter the heatmaps to those expression data from the selected branches of the UBERON tree.
  • TIN-X data now has a circular treemap plot alongside the scatter plot, based on the hierarchy defined by Disease Ontology (DO). The plots are interactive in that they highlight points on the scatterplot that correspond to the selected branch of the DO tree.
• Predicted Effects of Inhibiting Kinases on Cancers
  • We're now showing predictions from Ravenmehr et al. 2021. Navigate to the 'Predicted Diseases' component of the target details pages for kinases, or the 'Predicted Targets' component of the disease details pages for cancers to find that data.

• Previously, filtering a ligand list based on an UpSet chart for the Target Filter would find zero ligands. The problem is fixed.

3.12.0 (2022-05-01)

Added Features

• Use Cases
  • Pharos has many features to aid in knowledge discovery and hypothesis generation. The new Use Cases page highlights how Pharos' individual features can be used together to reveal patterns in the data.
• Twitter feed on the home page
  • This replaces the old firebase based listing of news and events, which was very rarely updated.
• Nearest Tclin Targets
  • For non-Tclin targets, the nearest upstream and downstream Tclin targets, based on KEGG pathways, are now shown on the Target Details pages.
• Performance improvements
  • Slow loading Target pages, and unfiltered list pages are now prerendered, and will load faster.

  • You can also download details of the alignment from blastp through the Data Download workflow.
• Updates on How to Link to Pharos
  • You can now link to a custom target list, just by passing the list of gene symbols or UniProt IDs into the URL. See the About Page for details.

Bug Fixes / Miscellaneous updates

  • The web server was occasionally restarting, and returning some 50x - Gateway Errors.
• Ligand structures on the Ligand Details pages would occasionally not update when moving from one page to another
• Better handling of missing, or non-unique, gene symbols

    • The Gene Symbol is used when it is available, and unique for targets in TCRD, otherwise the UniProt ID is used
  • Now when you search for a degenerate gene symbol (like HLA-A), the typeahead form will give you an option to compile a list of all targets with that gene symbol

3.10.0 (2022-01-06)

Added Features

• MONDO integration

  • Different sources for target-disease associations use different disease ontologies. Now Pharos uses the MONDO Disease Ontology to harmonize analogous terms.
    • Accordingly, navigating to parent or child disease terms from the Disease Details pages is done using the MONDO Ontology, rather than Disease Ontology (DO).
  • Now there is the added ability to resolve diseases based on any of the equivalent terms mapped to MONDO can be used to resolve to a Disease Details page (e.g. https://pharos.nih.gov/diseases/UMLS:C0004096)

• Combined ProtVista Structure and Sequence Viewer

  • Pharos has upgraded to EBI's Nightingale based web components, which has an integrated structure viewer along with the sequence viewer. This enables us to combine those two components of the Target Details pages.
  • Furthermore, the data from ProKino regarding Kinase annotations and ortholog sequence variants is also integrated into a single component.
  • AlphaFold structures are included along with the other structures.

• Angular Upgrade:

  • Upgrade to Angular 13

  • Long scrolling target details pages are now easier to navigate with subheadings that group descriptive data, behavioral data, phenotypic data, etc.

Bug Fixes / Miscellaneous updates

• Prefixes to resolve Ligands by specific IDs
  • Add a prefix to resolve to a specific ligand, in cases of ID collision between data sources. Available prefixes are: "CID:" for PubChem IDs, "DC:" for DrugCentral IDs, "G2P:" for Guide to Pharmacology IDs, "UNII:" for UNIIs, "name" for the compound name, and "LYCHI:" for LyCHI layer 4. Prefixes are case insensitive.
• Heatmaps can now be sorted by any row or column by clicking the labels
• Expression data can be filtered for cell types or tissues.

3.9.0 (2021-11-05)

Added Features

• List Pages have been restructured
  • There are now two views to toggle between on all list pages.
    • Table View - Shows the list of results (targets, diseases, or ligands) to page through to find the one you're interested in.
    • List Analysis - Shows the visualizations that summarize the list, and more advanced analysis tools to provide an overview of the population, which can help highlight common features of elements in the list, or provide a high level view of the structure of the data in the list.
• Custom Lists for Ligands and Diseases
  • Similarly to how custom lists of targets can be uploaded, now you can create your own custom lists of ligands and diseases. All the same functionality and visualizations are available for your custom lists as with all other lists in Pharos.
  • Ligands are resolved using NCATSFind which enables you to upload your lists as SMILES, ligand names, CAS Numbers, ChEMBL IDs, etc.
• Predicted Ligand Activities
  • Now, in addition to viewing active targets for a ligand, you can also see predicted targets for those ligands, based on QSAR model results from NCATS Predictor.
• Create Heatmaps
  • On List Analysis pages, heatmaps can be constructed to show an overview of data for items in the list.
  • For Target lists, you can construct a heatmap for:
    • All Active ligands, shaded according to the potency of the interaction
    • All Disease Associations, shaded according to the number of sources reporting the association
    • All Protein-Protein Interactions, shaded according to the String-DB Score
  • For Disease Lists, you can construct a heatmap for:
    • All Target Associations, shaded according to the number of sources reporting the association
  • For Ligand Lists, you can construct a heatmap for:
    • All Target Activities, shaded according to the potency of the interaction
• Calculate Filter Value Enrichment
  • On List Analysis pages, enrichment scores can be calculated to highlight the common features of the elements in the list
    • The side panel has always shown the counts of elements in the list that have each filter value, but the list is often dominated by very common values.
    • By calculating and sorting values by the enrichment scores, you can know which filter values in the list are represented more than expected by random chance.
• Improved Search Functionality
  • One text search will return combined results from Targets, Diseases, and Ligands, as well as many filter values.
• Updated database to TCRD 6.12.4
  • TCRD_v6.12.4.README

  • On list pages, a tab for UpSet charts is available to see the combinations of facet values for targets / diseases / ligands in the list
  • Filter the lists by clicking the bars or circles for a combination of values
  • Edit the facet values to create charts for any facet values. This can also be used to perform complex boolean logic between facet values (i.e. show a list of targets that have value A and B, but not C - select those values to build the UpSet chart, and select the right group to filter the list)
• Related tools are shown as tiles for targets that have data in those tools
  • DarkKinome, Resolulte, ProKino, TIGA, GENEVA, GlyGen, ARCHS4 all have tiles for the targets they have data for

• Search Similar Targets based on some multiple response target facets

  • You could always find targets that have a specific value for a target facet, for example, generate a target list of targets that have a "GO Function" of "drug binding". Now, target details pages have links to generate lists of targets that share overlapping values, ranked by the degree of overlap. For example, generate a list of targets that have the most "GO Functions" with "DRD2"
