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.

Deriving from bone marrow, the bone marrow mesenchymal stem cells (BMSCs) possess multipolar chemotaxis, proliferation potential, along with the capability to differentiate into various types of cells. Moreover, the hypoxic stimulation can effectively induce BMSCs differentiation. This study intends to explore the impediment of BMSCs on malignant behaviors of lung cancer stem cells under hypoxia. A co-culture system of BMSCs with A549 cells was established and then assigned into normoxia group, hypoxia group (50, 100, and 200 nmol/L) followed by analysis of cell viability by CCK-8 assay and miR-145 expression by qRT-PCR. In addition, A549 cells were grouped into NC group, miR-145-mimics group, and miR-145-inhibitors group followed by analysis of cell invasion and levels of miR-145 and Oct4. Hypoxia group exhibited a reduced cell viability and higher miR-145 expression (146.01±21.23%) compared to normoxia group (P < 0.05). Transfection of miR-145-mimic significantly upregulated miR-145 and decreased cell invasion (7.49±1.43%) compared with miR-145-inhibitors group or NC group (P < 0.05). Meanwhile, Oct4 level in miR-145-mimics group (0.934±2.98) was significantly decreased (P < 0.05). In conclusion, under hypoxia condition, the co-culture with BMSCs can upregulated miR-145 level, effectively reduce the viability of lung cancer stem cells and restrain proliferation capability.

Abstract Bone-marrow mesenchymal stem cells (BMSCs) have been used in the treatment of early steroid-induced osteonecrosis of the femoral head (SONFH). However, the hypoxic microenvironment in the osteonecrotic area leads to hypoxia-induced apoptosis of transplanted BMSCs, which limits their efficacy. Therefore, approaches that inhibit hypoxia-induced apoptosis of BMSCs are promising for augmenting the efficacy of BMSC transplantations. Our present study found that under hypoxia, expression of the long non-coding RNA (Lnc), transmembrane protein 235 (Tmem235), was down-regulated, expression of Bcl-2-associated X protein was up-regulated, expression of B-cell lymphoma-2 protein was down-regulated, and the apoptotic rate of BMSCs was over 70%. However, overexpression of Lnc Tmem235 reversed hypoxia-induced apoptosis of BMSCs and promoted their survival. These results demonstrated that Lnc Tmem235 effectively inhibited hypoxia-induced apoptosis of BMSCs. Mechanistically, we found that Lnc Tmem235 exhibited competitive binding to miR-34a-3p with BIRC5 mRNA, which is an inhibitor of apoptosis; this competitive binding relieved the silencing effect of miR-34a-3p on BIRC5 mRNA to ultimately inhibit hypoxia-induced apoptosis of BMSCs by promoting the expression of BIRC5. Furthermore, we co-cultured BMSCs overexpressing Lnc Tmem235 with xenogeneic antigen-extracted cancellous bone to construct tissue-engineered bone to repair a model of early SONFH in vitro. The results showed that overexpression of Lnc Tmem235 effectively reduced apoptosis of BMSCs in the hypoxic microenvironment of osteonecrosis and improved the effect of BMSC transplantation. Taken together, our findings elucidate that Lnc Tmem235 inhibited hypoxia-induced apoptosis of BMSCs by regulating the miR-34a-3p/BIRC5 axis, thus improving the transplantation efficacy of BMSCs for treating early SONFH.
