This study aims at investigating the mechanism underlying bone marrow mesenchymal stem cells (BMSC) function in glioma. Glioma cells were administered with plasmids loading NF-κB siRNA, microRNA (miRNA)-189 inhibitor, or miR-189 mimics for transfection followed by analysis of miR-189 expression by RT-qPCR, cell apoptosis by flow cytometry, cell proliferation by MTT assay,invasion and migration by Transwell assay, inflammatory factors secretion by ELISA as well as proteins expression by western blot. A mouse model of glioma was established to detect the in vivo effect of BMSCs. miR-189 was lowly expressed in glioma cell lines but enriched in BMSCs. When miR-189 was silenced, cell proliferation, invasion and migration were potentiated and apoptosis was decreased, along with enhancement of N-cadherin, Vimentin, MMP-2 and and MMP-9, and decline in Bax, cleaved casepase-3 and cleaved PARP. Silencing of NF-κB reversed the effect of miR-189 inhibitor on cell progression, accompanied with reduction of inflammatory factors. BMSCs treatment effectively promoted miR-189 expression in glioma and inactivated TNF-α/NF-κB signaling, thereby suppressing tumor growth. In conclusion, miR-189 derived from BMSC inhibits glioma progression through regulation of TNF-α/NF-κB signaling pathway.

Our study intends to assess the relationship between exosomes derived from bone marrow mesenchymal stem cells (BMSC-exo) and breast cancer. BMSC-exo were isolated and characterized by transmission electron microscopy. After transfection of BMSCs with miR-204 inhibitor, breast cancer cells were incubated with BMSC-exo followed by analysis of cell proliferation by CCK-8 assay, cell apoptosis by flow cytometry, and expression of apoptosis-related protein and NF-κB signaling by western blot. The co-culture of BMSC-exo with breast cancer cells enhanced miR-204 transcription, inhibited cell proliferation and induced apoptosis. Further, BMSC-exo accelerated apoptosis as demonstrated by the increased level of Bax and casepase-3 and decreased Bcl-2 expression, as well as reduced NF-κB signaling activity. But knockdown of miR-204 abolished the effect of BMSC-exo on apoptosis and proliferation with NF-κB signaling activation. In conclusion, miR-204 from BMSC-exo restrains growth of breast cancer cell and might be a novel target for treating breast cancer.

The α-calcitonin gene-related peptide (α-CGRP) regulates bone metabolism and has potential applications in enhancing bone remodeling in vivo. However, α-CGRP's role in bone marrow mesenchymal stem cells (BMSCs) osteogenic differentiation remain unclear. Rat BMSCs were separated into control group, α-CGRP group and α-CGRP siRNA group, in which BMSCs were transfected with α-CGRP plasmid and α-CGRP siRNA respectively followed by analysis of α-CGRP level by real time PCR and ELISA, cell proliferation by MTT assay, Caspase 3 activity, ALP activity, formation of calcified nodules by alizarin red staining, Smad1 and Smad7 level by Western blot and Runx2 by real time PCR. αCGRP transfection into BMSCs significantly up-regulated CGRP, which could promote cell proliferation, inhibit Caspase 3 activity, promote ALP activity, increase calcified nodules formation and upregulate Smad1, Smad7 and Runx2 compared to control (P < 0.05); transfection of αCGRP siRNA significantly down-regulated CGRP in BMSCs, inhibited cell proliferation, promoted Caspase 3 activity, inhibited ALP activity, inhibited calcified nodules formation and downregulate Smad1, Smad7 and Runx2 (P < 0.05). αCGRP overexpression promotes the Smad/Runx2 signaling, which in turn promotes BMSCs proliferation and osteogenesis. Decreased αCGRP level inhibits Smad/Runx2 signaling, promotes BMSCs apoptosis, inhibits proliferation and osteogenic differentiation.

Bone marrow mesenchymal stem cells (BMSCs) can be differentiated into different types of cells. SOX9 involves in the development and progression of various diseases. Our study aims to assess SOX9's effect on osteogenic differentiation of BMSCs and its related regulatory mechanisms. Rat BMSCs were isolated and randomly divided into control group, SOX9 group and SOX9 siRNA group, which was transfected with pcDNA-SOX9 plasmid or SOX9 siRNA respectively followed by analysis of SOX9 expression by Real time PCR, cell proliferation by MTT assay, Caspase3 and ALP activity, GSK-3β expression and Wntβ/Catenin Signaling pathway protein expression by Western blot, and expression of osteogenic genes Runx2 and BMP-2 by Real time PCR. Transfection of pcDNA-SOX9 plasmid into BMSCs significantly inhibited cell proliferation, promoted Caspase3 activity, decreased ALP activity and downregulated Runx2 and BMP-2, increased GSK-3β expression and decreased Wntβ/Catenin expression protein expression (P< 0.05). SOX9 siRNA transfection significantly promoted cell proliferation, inhibited Caspase3 activity, increased ALP activity and upregulated Runx2 and BMP-2, downregulated GSK-3β and increased Wntβ/Catenin expression. SOX9 regulates BMSCs proliferation and osteogenic differentiation through Wntβ/Catenin signaling pathway.

Bone marrow mesenchymal stem cells (BMSCs) can be used to treat bone defects. The neuropeptide substance P (SP) plays an important role in a variety of life activities. However, the effect of SP on BMSCs differentiation in high glucose environment remains unclear. Rat BMSCs were isolated and divided into control group; high glucose group; and SP group. The secretion of SP was detected by ELISA; cell proliferation was detected by MTT assay; apoptosis activity was detected by Cas-pase3 activity kit. Real time PCR was performed to measure Bax and Bcl-2 expression. Alizarin red staining was to detect calcified nodule formation. Western blot was done to measure AMPK/mTOR signaling protein expression. In high glucose environment, SP secretion was significantly decreased, along with increased cell proliferation, Caspase3 activity and Bax expression. Meanwhile, Bcl-2 expression, ALP activity and calcified nodules formation was significantly decreased with reduced AMPK phosphorylation and increased mTOR expression (P < 0.05). SP addition in high glucose environment significantly promoted SP secretion and cell proliferation, decreased Caspase3 activity and Bax expression, increased Bcl-2 expression, ALP activity and calcification nodules formation with increased AMPK phosphorylation and decreased mTOR expression (P < 0.05). In high glucose environment, SP secretion is decreased in BMSCs. Up-regulation of SP in BMSCs cells in high glucose environment inhibit the apoptosis of BMSCs and promote cell proliferation and osteogenesis by regulating AMPK/mTOR signaling pathway.
