you can now share pathways with a few clicks on Mastodon (thx to the PR by @larsgw) Click on the orange arrow bottom left of the pathway figure, click the Mastodon logo, and get a window to share on your fediverse server #fediverse #openscience #mastodon #biology

Screenshot of the https://www.wikipathways.org/pathways/WP5638 webpage, after clicking the orange "share" button (visible as the curve arrow mid left of the screenshot, right of the "download" icon). In front of it, it shows the WikiPathways "share" dialog with three URLs to share the page, but also a row of five logos for sharing to Facebook, Mastodon, Whatsapp, LinkedIn, and email (in that order). In front of all that, a second browser window with the Mastodon "Share to Mastodon" window, with the example text to share (defaulting to here to "Check out this pathway from @wikipathways@fosstodon.org: Fatty acid beta-oxidation https://www.wikipathways.org/instance/WP5638"), and a paragraph asking for "Your Mastodon Domain", and a big "Continue to Mastodon" button.

a new R package, PinPath, allows mapping experimental data onto pathways, using just R: https://doi.org/doi:10.18129/B9.bioc.PinPath https://bioconductor.org/packages/devel/bioc/html/PinPath.html #openscience #bioinformatics #bioconductor

Example SVG from the WikiPathways vignette of the PinPath packages with data mapped onto a pathway. The pathways is from a publication from 2022: https://doi.org/10.3389/fonc.2022.849640 "A Community-Driven, Openly Accessible Molecular Pathway Integrating Knowledge on Malignant Pleural Mesothelioma"

Genes/Proteins are colored by up- or downregulation, blue and red.

Milestone! "To date, 902 pathways have been cited a total of 3018 times" https://www.wikipathways.org/browse/citedin.html #biology #openscience

Screenshot of part of the linked webpage. It shows a list ("Pathways Cited in the Literature"), stating the fact listed in the main post, and then an alphabetically sorted list of pathways by name (but also with WP identifier), and for each, as sublist, DOI / PubMedCentral ID badges for the articles that cite that pathway. The screenshot shows that the first 10 pathways in the list of 1, 2, or 3 citations.

@Marvin upgraded our SPARQL interface. It now show a title and a description, and making it easier to navigate the example queries: https://sparql.wikipathways.org/ (maybe do a hard reload) #openscience #bioinformatics

Screenshot of the linked SPARQL endpoint interface. It shows three main panels below a title bar (which includes the endpoint URL). One panel shows the title, description, and SPARQL query currently being "edited". The right-hand side panel shows a list of queries, now with easier to read query names. The bottom panel is still the results table. The query used is the one listing all authors, sorted descending by the number of pathways they initiated. For each author, the number of pathways, their name, ORCID, and WikiPathways account page is listed.

December 2025 WikiPathways release: 840 edits by 8 contributors and 9 new pathways. Accessible via #webservices, #rstats, #pathvisio and #cytoscape. https://www.wikipathways.org/#download #bioinformatics #elixirnl

WikiPathways WP5609: Key metabolic pathways in melanoma, glycolytic pathway, TCA cycle, glutamine metabolism, and oxidative phosphorylation, with potential therapeutic targets and inhibitors. Inhibitors targeting critical metabolic nodes are outlined in teal. This pathway is based on Figure 1 in Shen et al.

WikiPathways WP5606: Cis- and trans-acting regulators shape gene expression within the β-globin cluster. The LDB1 complex (LDB1/LMO2/GATA1/TAL1) binds both the locus control region (LCR) and globin promoters, promoting chromatin looping to activate these genes—interactions that may be influenced by cis-acting variants linked to HbS haplotypes. Across the HBB gene cluster and its surrounding regions, BCL11A and ZBTB7A (LRF) binding sites are present, represented by red and blue stars. Each of these transcription factors recruits its own NuRD complex. MYB regulates HbF expression directly and also indirectly through KLF1 and BCL11A. Repression of the HbF genes is indicated by dashed lines. Inspired by figure 1 in Habara et al. (2017).

WikiPathways WP5604: This pathway shows the molecular pathophysiology of sickle cell disease. (A) A single–nucleotide variant in the β-globin gene replaces glutamic acid with valine at position 6 of the β-globin chain. Upon deoxygenation, the resulting hemoglobin S (HbS) molecules polymerize into rigid fibers, driving erythrocyte sickling (clockwise). (B) Sickled cells cause impaired blood rheology and enhanced adhesion of erythrocytes to neutrophils, platelets, and the endothelium, leading to slowed or obstructed microvascular flow – called vaso-occlusion. Vaso-occlusion in turn promotes ischemia-reperfusion (I-R) injury (clockwise). (C) HbS polymer formation also leads to red cell membrane damage and hemolysis (counterclockwise), releasing cell-free hemoglobin (Hb) into circulation. Oxygenated Hb (Fe²⁺) contributes to endothelial dysfunction by consuming nitric oxide (NO) and producing nitrate (NO₃⁻) and methemoglobin (Fe³⁺). Hb can also undergo Fenton chemistry with H₂O₂, generating hydroxyl radicals (•OH) and additional methemoglobin. Methemoglobin (Fe³⁺) can degrade and release cell-free heme (counterclockwise), a potent erythrocyte-derived DAMP. (D) ROS production, TLR4 activation, NET formation, release of tissue- or cell-derived DAMPs, extracellular DNA, and other yet-undefined mediators generated by cell-free heme or I-R injury can induce sterile inflammation by activating the inflammasome in vascular and immune cells, leading to IL-1β release.

WikiPathways WP5607: Erythroid lineage cell differentiation transitions from hematopoietic stem cells (HSCs) through successive erythroid progenitors – burst-forming unit–erythroid (BFU-E), colony-forming unit–erythroid (CFU-E) – then proerythroblasts (proEB), basophilic erythroblasts (basoEB), polychromatic erythroblasts (polyEB), and orthochromatic erythroblasts (orthoEB), then and ultimately to reticulocytes, pyrenocytes, and mature red blood cells (RBCs). Stage-specific transcription factors (GATA1, GATA2), surface markers (CD34, CD45, CD71, CD235a), the onset of hemoglobin expression, and other factors are also depicted.

Hi everyone, we have updated the author and community pages on our website. Authors can now find curation reports for pathways they started, and Communities can find those too. We hope you like it! https://github.com/wikipathways/wikipathways-help/discussions/203 #openscience #biology #biocuration

Screenshot of the COVID-19 Community page with the pathways curated by this community, showing thumbnails of 21 pathways along with full title and a curation report badge showing the number of curation events. These are colored by the number of events, mostly yellow (1-2 suggestions) and orange (3-4 suggestions) here.

Screenshot of Europe PMC for pathways of the COVID-19 Community page. It shows a few relevant journal articles mentioning specific COVID-19 pathways.
