Urine-derived stem cells (USC) are isolated from voided urine and have demonstrated potential for use in tissue engineering and regenerative medicine therapies. Clear cell renal cell carcinoma (ccRCC) is a common urological malignancy that originates in the kidney. Since USC also originate in the kidney, the objective of this study was to investigate any biological differences between USC isolated from healthy patients and those isolated from ccRCC patients (rc-USC). We found that USC can be isolated from the voided urine of ccRCC patients (rc-USC) and have a morphology and function similar to those isolated from healthy donors. However, the rc-USC showed greater proliferation and invasion capacity than USC, and possessed some features of cancer cells; but the rc-UC were not able to form xenografts when implanted in vivo. We further performed RNA sequencing of rc-USC and USC and found several differentially expressed lncRNAs and mRNAs; however subsequent GO and KEGG enrichment analysis showed few pathway differences between these cells. Bioinformatic analyses and RT-PCR showed the expression of several known ccRCC-related genes in rc-USC expressed, as compared to USC derived from healthy donors. This study demonstrates that rc-USC displayed several cellular and genetic features of ccRCC cells, which suggests that this population of cells could provide a non-invasive approach for for the diagnosis, predication, disease modeling and therapeutic strategies targeting ccRCC.The objective was to design a scaffold that could continuously deliver nerve growth factor (NGF) combined with neurally differentiated bone marrow mesenchymal stem cells (BMSCs) to promote better recovery of spinal cord injury (SCI) in rats. BMSCs were induced to differentiate into neurons for 6 days in vitro, and then seeded on a NGF persistent delivery scaffold, both were transplanted to SCI rats in combination. Relevant extensive tests were conducted 1, 4 and 8 weeks after transplantation. The results showed that the scaffold had a stable ability to continuously release NGF and that the BMSCs on the scaffold could successfully differentiate into nerve cells. The results of Bacco, Beattie and Bresnahan (BBB) scores, inclined plane tests and electrophysiological investigations revealed that the rats in the combined regimen had better locomotor functional recovery. The results of H&E/Nissl staining, Golgi staining and immunofluorescence showed that the rats in the combined regimen retained the most neurons and had the least cavities and more formations of dendritic spines. Similarly, the positive rate was high for MAP2, NeuN and MBP, and low for GFAP. The graft of the NGF persistent delivery scaffold seeded with neurally differentiated BMSCs significantly reduced the formation of cavities and glial scars at the SCI sites and promoted neuronal survival, axonal regeneration and locomotor function recovery. Compared with the single graft of NGF persistent delivery scaffold or the single graft of neurally differentiated BMSCs, this combined scheme had a better effect in promoting the recovery of SCI.
To clarify the regulatory effect of Nuclear-enriched abundant transcript 1 (NEAT1) on abdominal aortic aneurysm (AAA) model rats and isolated endothelial progenitor cells (EPCs).

The AAA rat model was established by CaCl
stimulation, and overexpressed NEAT1 was injected into rats through tail vein. Abdominal aorta lesions and numbers of EPCs in tissues and peripheral blood were examined by hematoxylin-eosin, immunofluorescence and flow cytometry. The extracted EPCs were identified by microscopy, DiI-ac-LDL staining and flow cytometry. Effect of overexpressed/silencing NEAT1 on the viability, migration, tube formation and VEGF content of EPCs was investigated by MTT-, wound-healing, tube formation assays and ELISA, respectively. IM156 datasheet The expressions of NEAT1, miR-204-5p, Angiopoietin-1 (Ang-1)/ERK pathway were determined by qRT-PCR and Western blot as needed. The targeting relationships between NEAT1 and miR-204-5p, and miR-204-5p and Ang-1 were predicted on starBase, TargetScan and confirmed by dual-luciferase experiments. The mutual regulation effect was studied through rescue experiments.

Overexpressed NEAT1 not only reduced inflammatory infiltration and increased the number of EPCs in abdominal aorta and peripheral blood, but also promoted the viability, migration, tube formation of EPCs, increased VEGF content and upregulated the expression of the Ang-1/ERK pathway in EPCs. However, silencing NEAT1 produced opposite results. NEAT1 targeting miR-204-5p inhibited the functional effects of miR-204-5p on of EPCs. Overexpressed/silencing Ang-1 partially reversed the effects of NEAT1 or miR-204-5p on the characteristics of EPCs.

NEAT1 competitively binds with miR-204-5p and up-regulates Ang-1 expression in EPCs to effectively improve the proliferation, migration and angiogenesis of EPCs.

Alternatively, Chinese herb medicine (CHM) offers a bright perspective for treating complex diseases. Mahuang Decoction (MHD), a classic CHM formula, has been widely used in treating respiratory diseases in China for centuries, but its action mechanism has yet to be fully investigated. In this study, we first systemically explore the action mechanism of MHD by using network pharmacology and bioinformatic analysis tools, which uncovered a potential "new use of old drug" for MHD in cancer treatment. The therapeutic effect of MHD on LC was then validated by oral administration of MHD in the immunodeficient mice bearing xenografted LC tumors. To better understand the pharmacological activity of MHD against LC, we next constructed a drug/disease-target PPI network composed of 252 putative core therapeutic targets of MHD using Cytoscape. The subsequent enrichment analysis for these targets suggested that MHD could affect the apoptosis and cell cycle of LC cells via impeding Akt/ERK signaling pathways. Notably, these in silico analysis results were further validated by a series of cellular functional and molecular biological assays. Thus, our results show that MHD holds a great potential in LC treatment.
