Synthesis and Macrodomain Binding of Gln-carba-ADPr-peptide.

Mono-ADP-ribosylation is a dynamic post-translational modification (PTM) with important roles in cell signalling. This modification occurs on a wide variety of amino acids, and one of the canonical modification sites within proteins is the side chain of glutamic acid. Given the transient nature of this modification (acylal linkage) and the high sensitivity of ADP-ribosylated glutamic acid, stabilized isosteres are required for structural and biochemical studies.

Expression profiling of extramedullary acute myeloid leukemia suggests involvement of epithelial-mesenchymal transition pathways.

Extramedullary (EM) colonization is a rare complication of acute myeloid leukemia (AML), occurring in about 10% of patients, but the processes underlying tissue invasion are not entirely characterized. Through the application of RNAseq technology, we examined the transcriptome profile of 13 AMLs, 9 of whom presented an EM localization. Our analysis revealed significant deregulation within the extracellular matrix (ECM)-receptor interaction and focal-adhesion pathways, specifically in the EM sites.

The Economic Burden of Chronic Myeloid Leukemia in Patients with Later Lines: Findings from a Real-World Analysis in Italy.

Introduction: Chronic myeloid leukemia (CML) is a hematopoietic myeloproliferative disorder that accounts for 20% of all leukemias of adults. The introduction of tyrosine kinase inhibitors (TKIs) (imatinib, bosutinib, dasatinib, nilotinib, ponatinib) has yielded significant benefits for patients with CML in terms of survival and quality of life. This real-world analysis evaluated the economic burden for managing patients with CML in 2nd or ≥ 3rd TKI lines in Italian settings of clinical practice.

Vitamin C Deficiency in Patients With Acute Myeloid Leukemia.

Vitamin C has been shown to play a significant role in suppressing progression of leukemia through epigenetic mechanisms. We aimed to study the role of vitamin C in acute myeloid leukemia (AML) biology and clinical course. To this purpose, the plasma levels of vitamin C at diagnosis in 62 patients with AML (including 5 cases with acute promyelocytic leukemia, APL),7 with myelodysplastic syndrome (MDS), and in 15 healthy donors (HDs) were studied.
