A role for macrophages under cytokine control in mediating resistance to ADI-PEG20 (pegargiminase) in ASS1-deficient mesothelioma. (PubMed, Pharmacol Rep)
Collectively, our data indicate that ADI-PEG20-inducible cytokines orchestrate argininosuccinate fuelling of ASS1-deficient mesothelioma by macrophages. This novel stromal-mediated resistance pathway may be leveraged to optimize arginine deprivation therapy for mesothelioma and related arginine-dependent cancers.

BAP1 loss is associated with higher ASS1 expression in epithelioid mesothelioma: implications for therapeutic stratification. (PubMed, Mol Cancer Res)
Alterations in arginine metabolism may sensitise cells to metabolic drugs and we find that BAP1-negative/ASS1-expressing MPM cell lines are more sensitive to ASS1 inhibition, although not to inhibition of purine synthesis by mizoribine. Importantly, BAP1w-/KO MeT5A become desensitised to arginine-deprivation by pegylated arginine deiminase (ADI-PEG20), phenocopying BAP1-negative/ASS1-expressing MPM cell lines. Implications: Our data reveal an inter-relationship between BAP1 and arginine metabolism, providing a potential means of identifying epithelioid MPM patients likely to benefit from ADI-PEG20.

A Phase 1 Study of ADI-PEG20 (Pegargiminase) Combined with Cisplatin and Pemetrexed in ASS1-Negative Metastatic Uveal Melanoma. (PubMed, Pigment Cell Melanoma Res)
ADIPemCis was well tolerated with modest disease stabilisation in metastatic UM. Further investigation of arginine deprivation is indicated in UM including combinations with immune checkpoint blockade and additional antimetabolite strategies.
