Article Abstract
Objective: To construct a lentiviral vector carrying human CUEDC1 gene, to establish leukemic cell line MOLT-4 stably expressing recombinant plasmid, to analyze the expression of CUEDC1 in MOLT-4 cells and to investigate its effect on the proliferation of MOLT-4 cells.
Methods: The CUEDC1 gene was amplified by RT-PCR, and then was subcloned into the lentiviral vector pCDH to generate a lentiviral vector pCDH-CUEDC1. Recombinant lentivirus was generated by co-transfection of 3 plasmids, and transfected into MOLT-4 cells. The Real-time PCR and Western blot were respectively applied to detect the expression of CUEDC1 mRNA and protein, the CCK-8 and colony formation assay were used to evaluate the effect of CUEDC1 on proliferation of MOLT-4 cells.
Results: The recombinant lentiviral vector pCDH-CUEDC1 had been constructed successfully. After infection of MOLT-4 cells with the lentivirus, the recombinant plasmid could stably up-regulate the expression of CUEDC1 and protein. The CCK-8 detection and colony formation assay showed that exogenous CUEDC1 could significantly promote cell growth and the colony formation of MOLT-4 cells.
Conclusion: The recombinant lentiviral vector carrying human CUEDC1 has been successfully constructed, exogenous CUEDC1 can significantly promote cell growth and the colony formation of MOLT-4 cells.

Background: Ischemic stroke (IS) is a common neurological disease with a significant financial burden but lacks effective drugs. This study sought to explore the mechanisms underlying MAP kinase-interacting serine/threonine-protein kinase 2 (MKNK2), a gene enriched in the hypoxia-inducible factor-1 (HIF-1) signaling, in IS-related neurological injury.
Methods: Middle cerebral artery occlusion/reperfusion (MCAO/R) and oxygen-glucose deprivation/reoxygenation (OGD/R) models were used in vivo and in vitro.

The accumulated knowledge on the biology of the HIV-1 virus has led to the emergence of technologies that exploit the architecture of retroviruses and their integration or vectorization properties. This field of study constitutes retroviral vectorology, democratized in laboratories by the use of lentiviral vectors. By hijacking retroviral assembly, other systems are emerging and are increasingly mentioned in recent literature.

Sickle cell disease (SCD) is an inherited blood disorder marked by the production of abnormal hemoglobin, leading to the distortion-or sickling-of red blood cells. The SCD arises from a single-point mutation that substitutes glutamic acid with valine at the sixth codon of the β-globin chain in hemoglobin. This substitution promotes deoxyhemoglobin aggregation, elevating red blood cell stiffness, and triggering vaso-occlusive and hemolytic repercussions.

Background: Multiplex gene-edited chimeric antigen receptor (CAR) T-cell therapies face significant challenges, including potential oncogenic risks associated with double-strand DNA breaks. Targeted microRNAs (miRNAs) may provide a safer, functional, and tunable alternative for gene silencing without the need for DNA editing.
Methods: As a proof of concept for multiplex gene silencing, we employed an optimized miRNA backbone and gene architecture to silence T-cell receptor (TCR) and major histocompatibility complex class I (MHC-I) in mesothelin-directed CAR (M5CAR) T cells.

CAR-T cell therapy has been proven effective in various autoimmune diseases, with most studies utilizing lentiviral-transduced CAR-T cells. In recent years, retroviral vector-transduced CAR-T cells-characterized by a high positivity rate, stable cell lines, and lower plasmid requirements-have attracted increasing attention. This article presents a complex case of a patient with SLE combined with APS and TBIRS.
