NOS1 expression predicts melanoma-dependent immune dysfunction

Individuals with cancer often exhibit dysfunctional immune signaling in response to interferon (IFN) stimulation. Furthermore, recent evidence indicates that pSTAT-1 levels, which are indicative of IFN responsiveness, in circulating immune cells are predictive of clinical outcome in melanoma patients. In this issue of the Journal of Clinical Investigation, Qiuzhen Liu and colleagues at Southern Medical University, Guangzhou, China determined that melanoma cells have differing capacity to dampen IFN responses in peripheral blood mononuclear cells and that NOS1 expression is indicative of the inhibitory potential of a particular melanoma. In melanoma patient metastases there was an inverse relationship between NOS1 expression and patient response to adoptive T cell therapy. These findings establish a link between a melanoma specific factors and immune dysfunction and suggest that NOS1 expression can be used as a predictive biomarker in melanoma.

Murine model of glucocorticoid-induced glaucoma

Patients with inflammatory diseases, including allergy, asthma, and autoimmune disorders are often prescribed glucocorticoids; however, a subset of patients develop secondary glaucoma in response to treatment and must stop use of these beneficial steroid hormones. In this issue of the Journal of Clinical Investigation, Val Sheffield and colleagues at the University of Iowa developed a murine model of glucocorticoid-induced glaucoma in which topical administration of 0.1% dexamethasone to the eye produces clinical hallmarks of human disease, including a substantial increase in intraocular pressure (IOP), functional and structural loss of retinal ganglion cells, axonal degeneration, and ECM alterations within cells of the trabecular meshwork (TM). Evaluation of human TM cells revealed chronic ER stress in response to dexamethasone. Moreover, increased IOP in response to dexamethasone was prevented in animals lacking the ER stress-associated transcription factor CHOP or treated with the chemical chaperone sodium 4-phenylbutyrate. These results indicate that ER stress contributes to the etiology of glucocorticoid-induced glaucoma and suggest that reducing ER stress has therapeutic potential for relieving elevated IOP.
