However, the molecular basis of GC-induced cell death remains elusive. Here, we show that GC suppresses mechanistic target of rapamycin complex 1 (mTORC1) signaling and that, conversely, oncogenic activation of mTORC1 confers resistance to GCs. Our genome-wide CRISPR/CRISPR-associated protein 9 (CRISPR/Cas9) dropout screens reveal that depletion of components of either the gap activity toward Rags 1 or tuberous sclerosis complexes, both negative regulators of mTORC1 signaling, significantly attenuates B-ALL cell sensitivity to dexamethasone. Dexamethasone primarily induces B-ALL cell death by downregulating mTORC1 activity, thus promoting autophagy and impairing protein synthesis. Dexamethasone treatment failed to suppress mTORC1 activity in B-ALL cells expressing mutant GC receptors lacking DNA-binding capacity, suggesting that dexamethasone transcriptionally represses mTORC1 activity. RNA-sequencing analysis identified multiple dexamethasone target genes that negatively regulate mTORC1 activity. Our findings suggest that GC sensitivity is significantly influenced by oncogenic stimuli and/or growth factors that activate the PI3K-AKT-mTORC1 pathway. This is consistent with the frequent GC resistance found in Ph and Ph-like ALLs.</p></div>","PeriodicalId":100189,"journal":{"name":"Blood Neoplasia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950328024000153/pdfft?md5=ab04dd4c2a9ccc8ef49f43cf5cbbb31a&pid=1-s2.0-S2950328024000153-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141090068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although multiple JAK inhibitors are currently approved and provide significant symptom improvement, these agents do not possess disease course modifying potential. Additionally, outcomes are poor for patients who fail JAK inhibitors, highlighting the need for novel mechanism-based therapies and innovative combination strategies. Selinexor, a novel Exportin 1 (XPO1) inhibitor that blocks nuclear export, increases nuclear localization and activity of p53 and other tumor suppressor pathways and decreases cytoplasmic activation of multiple proliferative and profibrotic pathways. Selinexor currently has approved indications in multiple myeloma and lymphoma, with broad potential applications in other malignancies, although it can be limited by toxicity in some settings. Selinexor has shown clinical activity and tolerability in MF, both as monotherapy and, particularly, in combination with ruxolitinib. The collective, early phase trial data support a phase 3 randomized, registration study of selinexor and ruxolitinib in patients with MF naïve to JAK inhibitor therapy.

Therefore, the phase 3 ARMADA 2000 trial was conducted in patients aged ≥50 years with relapsed or refractory AML. The study randomized patients between devimistat combined with high-dose cytarabine and mitoxantrone (CHAM) or 1 of 3 control treatment regimens without devimistat: high-dose cytarabine and mitoxantrone; mitoxantrone, etoposide, and cytarabine; or fludarabine, cytarabine, and filgrastim. Overall, 265 patients consented to participate from 56 sites across 11 countries, and 200 patients were randomized, 98 patients to the devimistat arm and 102 patients to the control arm.

COVID-19 can cause a cytokine storm with some patients benefiting from blockade of the proinflammatory cytokine, interleukin 6 (IL-6). Because Castleman disease (CD) is an atypical lymphoproliferative disorder that can involve a cytokine storm and often requires immunosuppressive therapies, including IL-6 inhibition, we sought to evaluate outcomes after COVID-19 and SARS-CoV-2 vaccination in patients with CD. We administered a survey in April 2021 to characterize experiences with COVID-19 and SARS-CoV-2 vaccination among 300 patients enrolled in ACCELERATE, a CD natural history registry. Among 128 respondents, the prevalence of SARS-CoV-2 infection (16/95, 17%), severe disease (1/16, 6%), vaccination rates (112/128, 88%), and vaccine adverse effects after dose 1 (62/112, 55%) were comparable with that of the general US population. Although there were 2 cases of CD flares occurring shortly after SARS-CoV-2 infection (n = 1) and vaccination (n = 1), &gt;100 patients that were infected and/or vaccinated did not experience CD flares. Among patients with CD, the median antispike titer 6 months after the second vaccine dose was comparable to that of individuals with other immune-related diseases and healthy populations. Despite being on immunosuppressive therapies, patients with CD do not appear to be at increased risk of poor COVID-19 outcomes and can mount a humoral response to SARS-CoV-2 vaccination.
