Assessing Methylation-Based Sequencing as a Risk-Stratifying Tool in MDS

Methylation-based sequencing appears to be a viable risk-assessment tool for myelodysplastic syndromes (MDS), according to a study presented at the 2023 American Society of Clinical Oncology Annual Meeting. “MDS risk stratification is key for [making] optimal treatment decisions. DNA methylation is associated with MDS biology due to frequent somatic mutations…

Epigenetic priming improves salvage chemotherapy in diffuse large B-cell lymphoma via endogenous retrovirus-induced cGAS-STING activation | Clinical Epigenetics

5-Azacytidine pretreatment resensitizes cisplatin-resistant DLBCL cell lines to cisplatin to varying degrees A platinum-based anti-neoplastic agent is an essential component of salvage regimens for aggressive lymphomas, for example, rituximab, gemcitabine, dexamethasone, and cisplatin (R-GDP) for relapsed/refractory DLBCL and Hodgkin lymphoma [21]. As a single agent in humans, cisplatin is administered…

Reprogramming of human peripheral blood mononuclear cells into induced mesenchymal stromal cells using non-integrating vectors

OCT4 alone was insufficient to reprogram PBMCs into iMSCs directly Previously, we reported that lentivirally expressed OCT4 could directly reprogram human cord blood CD34+ hematopoietic progenitor cells into iMSCs with very high efficiency11. Therefore, we first tried to convert human PBMCs into iMSCs by overexpressing OCT4 alone using a clinically…

Mouse study at USC reveals why leukemic mutation varies

A mechanism linked to a genetic mutation could help identify patients who are at higher risk of developing leukaemia. A new study published in Blood, focuses on a genetic mutation associated with leukaemia. While some individuals with this mutation remain healthy, others develop the disease. The researchers at the USC Stem…

DLBCL therapeutic strategies and gene-oriented treatment

Background Lymphoma is a group of heterogeneous hematological malignancies, which are classified into Hodgkin’s lymphoma (HL) and non-Hodgkin’s lymphoma (NHL). Diffuse large B-cell lymphoma (DLBCL) is the most common aggressive NHL. DLBCL can be divided into germinal center B-cell-like (GCB) subgroup and non-GCB subgroup according to the origin of cells….

Impact of gene alterations on clinical outcome in young adults with myelodysplastic syndromes

In general, more than half of MDS patients are diagnosed at age 75 years or older, and the incidence rate of MDS in patients under 50 years of age is as low as less than 1 per 100,000)3. The median number of gene mutations in patients with MDS has been found to…

Impact of DNA mutations on lifelong blood cell production uncovered — ScienceDaily

New research has uncovered how genetic mutations hijack the production of blood cells in different periods of life. Scientists at the Wellcome Sanger Institute, the Cambridge Stem Cell Institute, EMBL’s European Bioinformatics Institute (EMBL-EBI) and collaborators show how these changes relate to ageing and the development of age-related diseases, including…
