PDIA5 (Protein Disulfide Isomerase Family A Member 5)

PDIA5 and ARFIP1 are promising biomarkers and therapeutic targets for PanNEN. Further validation and clinical exploration are required.

Importantly, targeting PDIAs sensitized prostate cancer cells to the AR antagonist, enzalutamide. This study reveals a mechanism governing AR proteostasis in prostate cancer and positions PDIA1/5 as viable therapeutic targets.

Drug prediction analysis identified seven protein biomarkers as potential targets for immunotherapy, targeted therapies, and tumor chemotherapy. Further scRNA-seq analysis revealed significant expression differences between gastric tumor and normal tissues, particularly the upregulation of IQGAP1, which highlights its role in tumor growth.

In conclusion, this study comprehensively elucidates the crucial role of PDIA5 in the malignant progression of GBM. Downregulating PDIA5 can mitigate the malignant biological behavior of GBM both in vitro and in vivo, potentially improving the efficacy of treatment for clinical patients with GBM.

Because GSH was increased with L858R, we combined osimertinib with the GSH inhibitor buthionine sulfoximine in L858R cells and observed synergistic effects. The complexity of EGFR 19Del and L858R mutant cells was demonstrated by proteomics, transcriptomics, and metabolomics analyses. Therapeutic strategies for lung cancer with different EGFR mutations could be considered because of their different metabolic phenotypes.
