1,5-AG suppresses pro-inflammatory polarization of macrophages and promotes the survival of B-ALL in vitro by upregulating CXCL14.

B-lineage acute lymphoblastic leukemia (B-ALL) is one of the most common malignancies in children. Despite advances in treatment, the role of the tumor microenvironment in B-ALL remains poorly understood. Among the key components of the immune microenvironment, macrophages play a critical role in the progression of the disease.

1,5-Anhydroglucitol promotes pre-B acute lymphocytic leukemia progression by driving glycolysis and reactive oxygen species formation.

Background: Precursor B-cell acute lymphoblastic leukemia (pre-B ALL) is the most common hematological malignancy in children. Cellular metabolic reorganization is closely related to the progression and treatment of leukemia. We found that the level of 1,5-anhydroglucitol (1,5-AG), which is structurally similar to glucose, was elevated in children with pre-B ALL.

Three-dimensional culture of rat ovarian granulosa cells shows increased SPP1 and FGF7 expression through the PI3K/Akt pathway.

Ovarian granulosa cells (OGCs) play an essential role in the regulation of follicular growth and development. However, previous studies of OGCs have concentrated on traditional 2D cultures. In the present study, we used the hanging drop culture method to culture rat OGCs (rOGCs) and assessed the effects of 3D conditions on their proliferation and gene expression profiles.

Intratracheal administration of umbilical cord-derived mesenchymal stem cells attenuates hyperoxia-induced multi-organ injury heme oxygenase-1 and JAK/STAT pathways.

Background: Bronchopulmonary dysplasia (BPD) is not merely a chronic lung disease, but a systemic condition with multiple organs implications predominantly associated with hyperoxia exposure. Despite advances in current management strategies, limited progress has been made in reducing the BPD-related systemic damage. Meanwhile, although the protective effects of human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) or their exosomes on hyperoxia-induced lung injury have been explored by many researchers, the underlying mechanism has not been addressed in detail, and few studies have focused on the therapeutic effect on systemic multiple organ injury.

Cryo-Temperature Pretreatment Increases the Pro-Angiogenic Capacity of Three-Dimensional Mesenchymal Stem Cells the PI3K-AKT Pathway.

To increase the potential and effectiveness of three-dimensional (3D) mesenchymal stem cells (MSCs) for clinical applications, this study explored the effects of short cryo-temperature pretreatment on MSC function. Adipose-derived MSCs (A-MSCs) were cultured via the ordinary monolayer method and 3D hanging drop spheroid method. When the cells adhered to the wall or formed a spheroid, they were subjected to hypothermic stress at 4°C for 1 h and then divided into three recovery periods at 37°C, specifically 0, 12, and 24 h.

[Effect of miltirone on proliferation and apoptosis of leukemia THP-1 cells].

To investigate the toxicity and related mechanism of miltirone to human acute myeloid leukemia THP-1 cells. To be specific, the active components and targets of miltirone were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and the target proteins were converted into standard gene names with UniProt. Acute leukemia-rela-ted target genes were screened from GeneCards and DisGeNET.

Prior transfusion of umbilical cord mesenchymal stem cells can effectively alleviate symptoms of motion sickness in mice through interleukin 10 secretion.

Background: Motion sickness (MS) is a disease that occurs during unbalanced movement, characterized by gastrointestinal symptoms and autonomic nervous system activation. Current clinical treatments for MS are limited. Recent evidence indicates that the levels of pro-inflammatory cytokines increase during MS and are associated with an inner ear immune imbalance.

Pyridoxal-5'-Phosphate Promotes Immunomodulatory Function of Adipose-Derived Mesenchymal Stem Cells through Indoleamine 2,3-Dioxygenase-1 and TLR4/NF-B Pathway.

Adipose-derived mesenchymal stem cells (A-MSCs) are promising cellular therapies for the treatment of immune-mediated diseases. Non-gene editing technologies can improve the immune regulatory function of A-MSCs. Our preliminary experiments revealed that an active form of vitamin B6-pyridoxal-5'-phosphate (PLP)-plays an important role in regulating gene expression and cytokine secretion in A-MSCs .
