Article Abstract
Background/aim: Chronic lymphocytic leukemia (CLL) is currently incurable. CLL is characterized by disordered DNA methylation. The aim of the present study was to target methylation with methionine restriction in a patient with progressive CLL.
Case Report: Methionine restriction for the patient was achieved with a low-methionine vegan diet and oral recombinant methioninase (o-rMETase). The patient also received rituximab, once per week for four weeks, and acalabrutinib 100 mg, twice daily (bid) continuously. The patient's white blood cell count decreased by 95% from peak levels and extensive lymphadenopathy disappeared during combination treatment with o-rMETase, rituximab, and acalabrutinib.
Conclusion: The combination of methionine restriction and first-line chemotherapy resulted in an apparent complete response (CR) in a CLL patient, a rare event. The duration of the CR will be monitored, and additional CLL patients will be treated similarly in the future.

Aurora kinase A promotes trained immunity via regulation of endogenous S-adenosylmethionine metabolism.

Innate immune cells can acquire a memory phenotype, termed trained immunity, but the mechanism underlying the regulation of trained immunity remains largely elusive. Here, we demonstrate that inhibition of Aurora kinase A (AurA) dampens trained immunity induced by β-glucan. ATAC-seq and RNA-seq analysis reveal that AurA inhibition restricts chromatin accessibility of genes associated with inflammatory pathways such as JAK-STAT, TNF, and NF-κB pathways.

Hypervirulent (hvKp) and classical multidrug-resistant (MDR) strains belong to distinct lineages and hvKp are typically characterized by hypermucoid capsules that have been shown to limit horizontal gene transfer (HGT), including plasmid acquisition. However, the convergence of hypervirulence and MDR is increasingly common worldwide. When we profiled 127 antibiotic-susceptible hvKp strains, we found that most (86%) are highly permissive to plasmid transfer despite their capsules.

Metabolic dysfunction-associated steatohepatitis (MASH) affects a large proportion of the global population and is widely regarded as the fastest growing cause of hepatocellular carcinoma. Currently, approved therapeutic strategies for MASH are limited. Therefore, this study used the Connectivity Map (CMap) database to identify a candidate compound for MASH, evaluate its efficacy in experimental models, and explore its mechanism of action.

Background/aim: Metastatic colon cancer is a recalcitrant disease. Previous studies have shown efficacy of A1-R (A1-R), recombinant methioninase (rMETase), and chloroquine (CQ) on cancer cells as they target fundamental hallmarks of cancer. The present study examined these agents alone and all combinations against colon-cancer cells compared to normal fibroblasts.
