HucMSC-Ex alleviates DSS-induced colitis in mice by decreasing mast cell activation via the IL-33/ST2 axis.

Background: Inflammatory bowel disease (IBD) is a chronic inflammatory disease that poses challenges in terms of treatment. The precise mechanism underlying the role of human umbilical cord mesenchymal stem cell-derived exosome (HucMSC-Ex) in the inflammatory repair process of IBD remains elusive. Mucosal mast cells accumulate within the intestinal tract and exert regulatory functions in IBD, thus presenting a novel target for addressing this intestinal disease.

Platelet-rich plasma promotes MSCs exosomes paracrine to repair acute kidney injury via AKT/Rab27 pathway.

Acute kidney injury (AKI) is defined by rapid deterioration of renal function, and is a common complication in hospitalized patients. Among the recent therapeutic options, mesenchymal stem cells (MSCs) are considered a promising therapeutic strategy for damaged tissue repair. Platelet rich plasma (PRP) regulates mesenchymal cells to repair tissue damage through the release of growth factors.

Fetal bovine serum inhibits neomycin-induced apoptosis of hair cell-like HEI-OC-1 cells by maintaining mitochondrial function.

Aging and exposure to noise or ototoxic drugs are major causes of hair cell death leading to human hearing loss, and many agents have been developed to protect hair cells from apoptosis. Fetal bovine serum (FBS) is a fundamental ingredient in the culture medium of hair cell-like House Ear Institute Organ of Corti 1 (HEI-OC-1) cells, but there have been no reports about the function of FBS in HEI-OC-1 cell apoptosis. In this study, we found that FBS deprivation alone significantly increased HEI-OC-1 cell apoptosis in the absence of neomycin exposure and that the presence of FBS significantly inhibited HEI-OC-1 cell apoptosis after neomycin exposure compared to FBS-deprived cells.

The role and mechanism of miR-374 regulating the malignant transformation of mesenchymal stem cells.

MicroRNAs (miRNAs) play important roles in cell transformation and carcinogenesis. We have previously established a tumor cell line K3 transformed from rat bone marrow-derived mesenchymal stem cells (rBM-MSCs). However, the underlying mechanism involved in MSC transformation remains unclear.

High expression of dual-specificity phosphatase 5 pseudogene 1 (DUSP5P1) is associated with poor prognosis in acute myeloid leukemia.

The purpose of this study was to investigate the expression status of Dual-Specificity Phosphatase 5 Pseudogene 1 (DUSP5P1) and its clinical relevance in patients with acute myeloid leukemia (AML). Real-time quantitative PCR (RQ-PCR) was performed to detect the status of DUSP5P1 expression in 89 patients with de novo AML and 24 normal controls. The level of DUSP5P1 expression was significantly up-regulated in AML compared to controls (P=0.

Over-expression of miR-675 in formalin-fixed paraffin-embedded (FFPE) tissues of breast cancer patients.

Background: Dysregulation of miR-675 has been found in a variety of solid tumors. MiR-675 has been suggested as having both oncogenic and tumor suppression properties in cancer. However, there is no evidence whether miR-675 is involved in breast cancer.

MOK overexpression is associated with promoter hypomethylation in patients with acute myeloid leukemia.

Overexpression of MAPK/MAK/MRK overlapping kinase (MOK) has been found in various tumors. However, the mechanism underlying MOK upregulation remains unclear. A CpG island was identified in MOK promoter.

Decreased SFRP2 expression is associated with intermediate and poor karyotypes in de novo acute myeloid leukemia.

Dysregulation of secreted frizzled-related protein 2 (SFRP2) has been found in various cancers. However, it is little known about the pattern of SFRP2 expression in acute myeloid leukemia (AML). This study was aimed to analyze the expression status of SFRP2 gene in AML patients and explore its clinical significance using real-time quantitative PCR (RQ-PCR).
