[Genetic Mutation Profile and Risk Stratification of Cytogenetically Normal Acute Myeloid Leukemia with Mutations Based on Multi-Gene Sequencing].

Objective: To evaluate the gene mutation profile and prognostic significance of adult cytogenetically normal acute myeloid leukemia (CN-AML) with mutation.

Methods: Targeted sequencing was implemented on the diagnostic bone marrow DNA samples of 141 adult CN-AML subjects with mutation. The nomogram model for leukemia-free survival (LFS) rate was generated by combining genetic abnormalities and clinical data.

Bone Marrow Endothelial Progenitor Cells remodelling facilitates normal hematopoiesis during Acute Myeloid Leukemia Complete Remission.

Although acute myeloid leukemia (AML) affects hematopoietic stem cell (HSC)-supportive microenvironment, it is largely unknown whether leukemia-modified bone marrow (BM) microenvironment can be remodeled to support normal hematopoiesis after complete remission (CR). As a key element of BM microenvironment, endothelial progenitor cells (EPCs) provide a feasible way to investigate BM microenvironment remodeling. Here, we find reduced and dysfunctional BM EPCs in AML patients, characterized by impaired angiogenesis and high ROS levels, could be partially remodeled after CR and improved by N-acetyl-L-cysteine (NAC).

Identification of a novel anti-ROR1 nanobody through phage display and its biochemical characterization.

In this study, we aimed to develop nanobodies targeting receptor tyrosine kinase-like orphan receptor 1 (ROR1) for cancer diagnosis and therapy. We immunized alpacas with ROR1, extracted RNA from their blood, and converted it to complementary DNA (cDNA) to amplify the VHH (variable domain of heavy-chain antibodies) sequence. This sequence was used to construct a phage library with a capacity of 8 ×10.

Tumor-derived miR-9-5p-loaded EVs regulate cholesterol homeostasis to promote breast cancer liver metastasis in mice.

Cancer cells secrete extracellular vesicles (EV) encapsulating bioactive cargoes to facilitate inter-organ communication in vivo and are emerging as critical mediators of tumor progression and metastasis, a condition which is often accompanied by a dysregulated cholesterol metabolism. Whether EVs are involved in the control of cholesterol homeostasis during tumor metastasis is still undefined and warrant further investigation. Here, we find that breast cancer-derived exosomal miR-9-5p induces the expression of HMGCR and CH25H, two enzymes involved in cholesterol synthesis and the conversion of 25-hydroxycholesterol from cholesterol by targeting INSIG1, INSIG2 and ATF3 genes in the liver.

Outcomes of allogeneic hematopoietic stem cell transplantation versus intensive chemotherapy in patients with myeloid sarcoma: a nationwide representative multicenter study.

Myeloid sarcoma (MS) is a rare hematological neoplasm with poor prognosis, posing a significant clinical challenge due to the absence of effective and standardized treatments. We conducted a retrospective analysis of 162 MS patients treated at 12 centers to compare outcomes between intensive chemotherapy and allogeneic hematopoietic stem cell transplantation (allo-HSCT). Our analysis revealed that allo-HSCT demonstrated superior overall survival (OS) within the initial 36 months compared to intensive chemotherapy alone (p = 0.

Letermovir prophylaxis for cytomegalovirus is associated with risk of post-transplant lymphoproliferative disorders after haploidentical stem cell transplantation.

Treatment of minimal residual disease in myeloid malignancies after allo-HSCT with venetoclax-based regimens in patients ineligible for or failed in the immunotherapy.

Background: Relapse was the major cause of treatment failure in patients with myeloid malignancies after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Patients who still suffer from the disease while cannot be detected by morphological analysis can be identified by the minimal residual disease (MRD) monitoring. The most used first-line regimens for MRD are immunotherapies.

Long-Term Survival and Immune Reconstitution of Donor-Derived Chimeric Antigen Receptor T-Cell Therapy for Childhood Molecular Relapse of B-Cell Acute Lymphoblastic Leukemia After Allogeneic Hematopoietic Stem Cell Transplantation.

Measurable residual disease (MRD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an independent risk factor for relapse in patients with acute lymphoblastic leukemia (ALL). This study aimed to assess the efficacy, safety, and immune reconstitution of chimeric antigen receptor T-cell (CAR-T) therapy in patients with molecular relapse after allo-HSCT. Eleven patients with molecular relapse of B-cell-ALL who underwent CAR-T therapy after allo-HSCT were enrolled.

Interactions between mild depressive symptoms and amyloid pathology on the trajectory of neurodegeneration, cognitive decline, and risk of Alzheimer's disease.

Background: Alzheimer's disease (AD) was driven by the interplay between modifiable environmental factors and β-amyloid (Aβ) pathology. We aimed to investigate the interaction effects of mild depressive symptoms (MDS) with Aβ on AD development.

Methods: Longitudinal data of 1746 non-demented adults (mean age = 73 years, female = 53 %, maximum = 10 years) were derived from the Alzheimer's Disease Neuroimaging Initiative cohort.
