CRKL but Not CRKII Contributes to Hemin-Induced Erythroid Differentiation of CML

[Journal of Cellular and Molecular Medicine] miR-429-CT10 regulation of kinase-like (CRKL) upregulation was negatively correlated with miR-429 downregulation in both chronic myeloid leemia (CML) patient and CR patient samples.

Myospreader Improves Gene Editing in Skeletal Muscle by Myonuclear Propagation

[Proceedings Of The National Academy Of Sciences Of The United States Of America] By screening nuclear localization signals and nuclear export signals, researchers identified “Myospreader,” a combination of short peptide sequences that promoted myonuclear propagation.

FLT3L Governs the Development of Partially Overlapping Hematopoietic Lineages in Humans and Mice

[Cell] The authors described three humans homozygous for a loss-of-function FMS-related tyrosine kinase 3 ligand (FLT3L) G variant with a history of various recurrent infections, including severe cutaneous warts.

Targeting Hyperactive Platelet-Derived Growth Factor Receptor-β Signaling in T Cell Acute Lymphoblastic Leukemia and Lymphoma

[Haematologica] Investigators reported a novel MYH9::PDGFRB fusion in a T-cell lymphoblastic lymphoma patient, and demonstrated that this fusion product was constitutively active and sufficient to drive oncogenic transformation in vitro and in vivo.

Molecular, Clinical, and Therapeutic Determinants of Outcome in NPM1 Mutated Aml

[Blood] Researchers analyzed a large group of patients with NPM1mutated AML enrolled in prospective trials to delineate the impact of baseline molecular and clinical features, post induction measurable residual disease status and treatment intensity on outcome.

Treatment of Chronic-Phase Chronic Myeloid Leukemia in Patients Randomized to Dasatinib or Imatinib after Suboptimal Responses to Three Months of Imatinib Therapy: Final 5-Year...

[Haematologica] DASCERN was a prospective, Phase IIb, randomized trial evaluating a switch to dasatinib in patients who have not achieved early molecular response after three months of treatment with first-line imatinib.

A Phase IIIb Study of Venetoclax and Azacitidine or Decitabine in an Outpatient Setting in Patients with Acute Myeloid Leukemia

[Hematological Oncology] This study evaluated the efficacy and safety of venetoclax plus hypomethylating agent in a United States community–based outpatient setting in patients with newly diagnosed AML who were treatment naïve for AML.

Aberrant Ecotropic Viral Integration Site-1 (EVI-1) and Myocyte Enhancer Factor 2 C Gene (MEF2C) in Adult Acute Myeloid Leukemia Are Associated with Adverse T...

[Annals Of Hematology] This prospective study involved 80 adult de novo AML patients recruited from Oncology Center, Mansoura University, between March 2019 and July 2021. The MEF2C and EVI1 expression were measured using a Taqman probe-based qPCR assay.

Provectus Biopharmaceuticals Announces Notice of Allowance for US Patent of Oral Administration of Rose Bengal Sodium in Hematology (Leukemia)

[Provectus Biopharmaceuticals, Inc.] Provectus Biopharmaceuticals, Inc.announced that the United States Patent and Trademark Office has allowed patent application 17/232,393, titled “Halogenated Xanthene Composition and Method for Treating Hematologic Cancers”.

Vascular Architecture Regulates Mesenchymal Stromal Cell Heterogeneity via P53-PDGF Signaling in the Mouse Incisor

[Cell Stem Cell] Using adult mouse incisors as a model, scientists uncovered the role of Trp53 in regulating vascular composition through THBS2 to maintain mesenchymal tissue homeostasis.

YTHDF2-Mediated m6A Methylation Inhibition by miR27a as a Protective Mechanism against Hormonal Osteonecrosis in BMSCs

[BMC Musculoskeletal Disorders] Researchers compared miR27a, YTHDF2, and total m6A mRNA levels in steroid-induced necrosis of the femoral head-affected and control bone marrow MSCs. CCK-8 and TUNEL assays were used to assess BMSC proliferation and apoptosis.

MEG3 Shuttled by Exosomes Released from Human Bone Marrow Mesenchymal Stem Cells Promotes TP53 Stability to Regulate MCM5 Transcription in Keloid Fibroblasts

[The Journal of Gene Medicine] Exosomes were isolated from human bone marrow MSCs (hBMSC), and keloid fibroblasts (KFs) were treated with exosomes derived from hBMSC. Cell counting kit-8, wound healing, transwell invasion, immunofluorescence, and western blot assays were conducted to study the malignant phenotype of KFs.
