Outcomes of patients with relapsed or refractory classic Hodgkin lymphoma after frontline brentuximab vedotin
Abstract Frontline therapy for classic Hodgkin Lymphoma (cHL) incorporating brentuximab vedotin (BV) improves outcomes compared with traditional chemotherapy, but up to 20% of patients relapse and need salvage treatment. Prior retrospective studies examining salvage therapies are mostly limited to patients who received chemotherapy-based treatment in frontline without novel agents.
Pharmacologic activation of integrated stress response kinases inhibits pathologic mitochondrial fragmentation
eLife Assessment This important study identifies a new class of small molecules that activate the integrated stress response (ISR) via the kinase HRI. Convincing evidence, including the image analysis pipeline, indicates that two of these compounds promote mitochondrial elongation and protect against mitochondrial fragmentation caused by chemical stress conditions or by genetic alterations.
Pharmacologic Activation of Integrated Stress Response Kinases Inhibits Pathologic Mitochondrial Fragmentation
Abstract Excessive mitochondrial fragmentation is associated with the pathologic mitochondrial dysfunction implicated in the pathogenesis of etiologically-diverse diseases, including many neurodegenerative disorders. The integrated stress response (ISR) - comprising the four eIF2alpha kinases PERK, GCN2, PKR, and HRI - is a prominent stress-responsive signaling pathway that regulates mitochondrial morphology and function in response to diverse types of pathologic insult.
