Exosome-Mediated Lectin Pathway and Resistin-MIF-AA Metabolism Axis Drive Immune Dysfunction in Immune Thrombocytopenia.

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by reduced platelet levels and heightened susceptibility to bleeding resulting from augmented autologous platelet destruction and diminished thrombopoiesis. Although antibody-mediated autoimmune reactions are widely recognized as primary factors, the precise etiological agents that trigger ITP remain unidentified. The pathogenesis of ITP remains unclear owing to the absence of comprehensive high-throughput data, except for the belated emergence of autoreactive antibodies.

Molecular glue degrader for tumor treatment.

Targeted Protein Degradation (TPD) represented by Proteolysis-Targeting Chimeras (PROTAC) is the frontier field in the research and development of antitumor therapy, in which oral drug HP518 Receives FDA Proceed Authorization for its IND Application for Prostate Cancer Treatment. Recently, molecular glue, functioning via degradation of the target protein is emerging as a promising modality for the development of therapeutic agents, while exhibits greater advantages over PROTAC, including improved efficiency, resistance-free properties, and the capacity to selectively target "undruggable" proteins. This marks a revolutionary advancement in the landscape of small molecule drugs.

Multiple small-dose infusions of G-CSF-mobilized haploidentical lymphocytes after autologous haematopoietic stem cell transplantation for acute myeloid leukaemia.

This retrospective study analysed 106 acute myeloid leukaemia (AML) patients undergoing autologous haematopoietic stem cell transplantation (ASCT) to assess the impact of multiple small-dose infusions of granulocyte-colony-stimulating factor (G-CSF)-mobilized haploidentical lymphocytes as post-ASCT maintenance therapy. Among them, 50 patients received lymphocyte maintenance therapy, 21 received alternative maintenance therapy, and 35 received no maintenance therapy. Patients receiving lymphocyte maintenance therapy demonstrated significantly higher overall survival (OS) and disease-free survival (DFS) compared to those without maintenance therapy, with 4-year OS and DFS rates notably elevated.

The impact of gut microbial signals on hematopoietic stem cells and the bone marrow microenvironment.

Hematopoietic stem cells (HSCs) undergo self-renewal and differentiation in the bone marrow, which is tightly regulated by cues from the microenvironment. The gut microbiota, a dynamic community residing on the mucosal surface of vertebrates, plays a crucial role in maintaining host health. Recent evidence suggests that the gut microbiota influences HSCs differentiation by modulating the bone marrow microenvironment through microbial products.

Bispecific antibodies and dual-targeting CAR-T cells for multiple myeloma: latest updates from the 2023 ASCO annual meeting.

Bispecific antibodies (BsAbs) and dual-targeted chimeric antigen receptor T (CAR T) cells have been employed in relapsed/refractory multiple myeloma (RRMM) patients over the past few years, as an increasing number of patients were ineffectively treated by ≥ 3 prior lines of therapy. BCMA/CD3 and GPRC5D/CD3 are the most popular combinations. Clinical findings indicated that patients exhibit a greater susceptibility to stronger and more enduring responses.

A retrospective study of autologous hematopoietic stem cell transplantation for peripheral T-cell lymphoma: pre-transplant patients with partial remission benefit from post-transplant maintenance therapy.

Background: Whether autologous hematopoietic stem cell transplantation (ASCT) improves the survival of patients with peripheral T-cell lymphoma (PTCL) remains controversial. Some studies have demonstrated that the efficacy of ASCT is superior in patients with complete remission (CR), whereas patients with partial remission (PR) remain vulnerable to relapse after ASCT, resulting in decreased survival rates. Maintenance therapy after chemotherapy may reduce the relapse rate of PTCL and improve survival; however, the role of maintenance therapy after ASCT in PTCL remains unclear.

Depletion of circ_0007841 inhibits multiple myeloma development and BTZ resistance via miR-129-5p/JAG1 axis.

Circular RNAs (circRNAs) possess important regulatory effects on multiple myeloma (MM) progression. Here, we aimed at exploring the function of circ_0007841 in MM and the underlying molecular mechanism. Expression of circ_0007841, microRNA (miR)-129-5p and Jagged1 (JAG1) was determined via qRT-PCR or western blot assay.

LINC00963 facilitates acute myeloid leukemia development by modulating miR-608/MMP-15.

Despite continuous improvements of AML therapy, the prognosis of AML patients remains unsatisfactory. Recently, lncRNAs have been reported to participate in the development of AML. Our data demonstrated that MMP15 and LINC00963 were upregulated and miR-608 was decreased in AML cells (THP-1, HL-60, HEL and MOLM-13) compared to HS-5 cells.

Circ_0007841 promotes the progression of multiple myeloma through targeting miR-338-3p/BRD4 signaling cascade.

Background: The pathogenesis of multiple myeloma (MM) is not completely known. Uncovering the potential mechanism of MM initiation and progression is essential for identifying novel diagnostic and therapeutic targets. Herein, we explored the function and the working mechanism of circular RNA circ_0007841 in MM progression.

Recent updates on CAR T clinical trials for multiple myeloma.

Proteasome inhibitors, immunomodulatory agents and monoclonal antibodies have dramatically changed the natural history of multiple myeloma (MM). However, most patients eventually suffer a relapse and succumb to the disease. Chimeric antigen receptor (CAR) engineered T cells targeting B cell maturation antigen (BCMA), CD138, CS1 glycoprotein antigen (SLAMF7) and light chains are in active development for therapy of refractory /relapsed (RR) MM.

Analysis of the efficacy and safety of bortezomib for treating newly diagnosed multiple myeloma through different administration methods.

Background: This study aims to compare the efficacy and adverse reactions of bortezomib for treating newly diagnosed multiple myeloma (MM) through two different administration methods: intravenous (IV) injection and subcutaneous (SC) injection.

Methods: A retrospective analysis was performed in 205 patients with newly diagnosed MM, who were treated by the Department of Hematopathology, Henan Cancer Hospital, from June 2009 to December 2017. These patients were divided into two groups according to the treatment methods: IV injection group, IV injection of bortezomib; SC injection group, SC injection of bortezomib.

The Biological Function and Clinical Significance of miR-886-5p in Multiple Myeloma.

Background: miR-886-5p plays an important role in many tumors, but it has been rarely investigated in multiple myeloma (MM). We studied the expression of miR-886-5p in the plasma of MM patients and in MM cell lines, and evaluated its biological function to identify its potential involvement in MM.

Methods: We recruited 16 subjects including 10 newly diagnosed MM patients who had not received treatment and 6 healthy individuals.

Universal CARs, universal T cells, and universal CAR T cells.

Currently, the two approved T cell products with chimeric antigen receptors (CAR) are from autologous T cells. These CAR T cells approved for clinical use must be generated on a custom-made basis. This case-by-case autologous T cell production platform remains a significant limiting factor for large-scale clinical application due to the costly and lengthy production process.

Results: The curative efficiency of the patients before transplantation was 9(22.

Clinical observation of recombinant human endostatin in treating relapsed refractory multiple myeloma.

Recombinant human endostatin (rhES) can inhibit multiple myeloma, while its clinical efficacy in treating relapsed refractory multiple myeloma (RRMM) has not been assessed. One hundred and eleven RRMM patients were treated with four different regimens: combination of VD (velcade+dexamethasone) and rhES (n = 25), Thalidomide (Tha) and VD (VTD, n = 22) combination, rhES and conventional chemotherapy combination (n = 32), and combination of conventional chemotherapy and Tha (n = 32). Significant differences were found in progression-free survival (PFS) between rhES combination groups and conventional chemotherapy combination groups.

DDX51 gene promotes proliferation by activating Wnt/β-catenin signaling in breast cancer.

Breast cancer was a malignant tumor seriously threatening the life of women in the world. But the prognosis of breast cancer patients was not so satisfactory due to the limited effective therapeutics. The heterogeneity decided that more than one gene or one signaling pathway was responsible for the initiation or progression of breast cancer.
