Scientists discover how the body's killer cells attack cancer

Researchers have found that natural killer cells instinctively recognize and attack the XPO1 protein, which drives cancer growth. By targeting this protein, scientists may be able to activate more killer cells to destroy cancer cells. The study suggests that this approach could lead to personalized cancer treatment with less side effects.

Protein identified as a potential biomarker and therapeutic target for aggressive neuroendocrine carcinomas

Researchers have identified UCHL1, a protein found in highly aggressive neuroendocrine carcinomas and neuroblastoma, as a potential molecular biomarker for diagnosing these cancers and predicting responses to therapy. Targeting UCHL1 with inhibitors has been shown to delay the growth and spread of these tumors in pre-clinical models.

A potential early esophageal cancer antigen: DDX53

Researchers found that tumor-resident T-cell receptor sequences showed high complementarity with the cancer testis antigen DDX53, suggesting an immune response that selects for DDX53-negative cells. This association was correlated with worse disease-free survival rates, highlighting a potential early esophageal cancer antigen.

Lurbinectedin for Neuroendocrine Tumors (NETs)

Researchers discuss lurbinectedin as a method to treat neuroendocrine tumors (NETs), with encouraging results from phase II basket studies demonstrating activity in platinum-sensitive relapsed SCLC and other malignancies. Lurbinectedin's mechanism of action involves inhibiting oncogenic transcription, promoting apoptosis and cell death.

Researchers found that Merkel cell carcinoma (MCC) Glypican-3 (GPC3) is expressed in nearly 70% of MCC tumors and up to 90% of MCPyV-negative cases. GPC3 expression is associated with worse prognosis, including increased risk of death from MCC. This makes GPC3 a promising target for chimeric antigen receptor T cell therapy.
