GSDME as a Radioligand Therapy Target
GSDME, gasdermin E, is a cell-surface protein. In Human Protein Atlas immunohistochemistry, GSDME staining is highest in lymphoma (100% of samples positive), thyroid cancer (100% of samples positive) and pancreatic cancer (90% of samples positive). Clinical status: Discovery-stage (no clinical drug program).
Is GSDME a good radioligand therapy target?
Scored against the six criteria that decide whether a protein can become a radioligand therapy:
- ✅ Cell-surface accessibility: Localized to the cell surface, so a radioligand can reach it from circulation.
- ✅ Tumor expression: High IHC staining in lymphoma, 100% of samples positive.
- ❔ Internalization: Not yet assessed.
- ⚠️ Clinical precedent: Discovery-stage (no clinical drug program)
- ❔ Shedding: Not yet assessed.
- ❔ Normal-tissue dosimetry: Check kidney, liver, bone marrow and salivary expression in the Human Protein Atlas tissue atlas.
GSDME expression in cancer
Protein expression of GSDME across 20 cancer types from Human Protein Atlas immunohistochemistry. The score is a weighted staining intensity from 0 to 1; "% positive" is the share of patient samples with detectable staining.

Is GSDME internalized?
Nuclens has not yet extracted internalization evidence for GSDME. Internalization matters for radioligands because an internalizing receptor traps the radionuclide inside the tumor cell. Run a full analysis to pull the latest literature.
GSDME clinical trials
Discovery-stage (no clinical drug program). Nuclens hasn't indexed trials for GSDME yet. Search ClinicalTrials.gov for GSDME trials.
GSDME normal tissue expression
Normal-tissue expression in dose-limiting organs (kidney, liver, bone marrow, salivary glands) drives radioligand dosimetry risk. Nuclens is re-validating its normal-tissue values, so they are not shown here yet. See GSDME in the Human Protein Atlas tissue atlas, and read how normal-tissue expression predicts radioligand dosimetry risk.
GSDME gene essentiality (DepMap)
CRISPR knockout effect across 1258 cancer cell lines: -0.01 (not essential). Radioligands kill by radiation, not by blocking the target, so essentiality matters less than for inhibitors. A non-essential target can still be an excellent radioligand target.
