Osteosarcoma (OS) is the most common primary malignant bone tumor worldwide. Recently, several studies have shown that the long non-coding RNA (lncRNA) CDKN2B-AS1 plays a critical role in several cancers. However, the function and underlying mechanism of CDKN2B-AS1 in OS development remains elusive. In this study, we firstly assessed the expression of CDKN2B-AS1 in OS tissues and cells, showing that CDKN2B-AS1 expression were remarkably upregulated in OS tissues and cells. Moreover, CDKN2B-AS1 k...

During hematogenous metastasis, cancer cells escape from primary lesions and enter into the circulatory system, and only a few can colonize distant organs. However, the mechanism of cell survival and metastasis in the hematopoietic environment remains unclear. Angiorrhea is the character of pathological neovascularization in malignant tumors and commonly detected in osteosarcoma (OS), a bone tumor that prefers circulatory metastasis. In the present study, we focused on the notable role of serum ...

Growing evidence suggests the crucial role of microRNAs (miRNAs) in regulating basic cell functions, and therefore participating in the pathologic development of diverse human diseases, including cardiac hypertrophy. Herein, we explained that miR-4458 was distinctly stimulated in Ang II-stimulated hypertrophic H9c2 cells. Intriguingly, miR-4458 inhibition led to exacerbated hypertrophic phenotypes in Ang II-treated H9c2 cells. In addition, the compensatory upregulation of miR-4458 in Ang II-trea...

Cervical cancer is among the most prevalent malignancies for women. An increasing number of evidences have been proved that long non-coding RNAs (lncRNAs) play significant role in the initiation and progression of cervical cancer. However, the function of long intergenic non-protein coding RNA 319 (LINC00319) in cervical cancer still remains vague. In this study, our purpose was to investigate the effects of LINC00319 on cell migration, invasion and epithelial-mesenchymal transition (EMT) proces...

Invasive mucinous adenocarcinoma of the lung (IMA), a mucinous variant of lung adenocarcinoma, is strongly linked with a worse prognosis. Therefore, a deeper understanding about its molecular mechanism may conduce to a promising IMA therapy. Long non-coding RNAs (lncRNAs) have recently caught great attention for their crucial roles in diverse diseases regarding tumor initiation and progression. However, the potential role of the lncRNA HOXC-AS3 IMA is not well established. Hence, the purpose of ...

Lentiviral expression vectors for calcitonin gene-related peptide (CGRP) were used to transfect rat bone marrow mesenchymal stem cells (MSCs). After assessing the biological characteristics of proliferation and aging in MSCs transfected with CGRP, we observed the effects of the CGRP-modified rat MSCs on the migration and proliferation of rat vascular smooth muscle cells (VSMCs) in vitro. Rat MSCs were isolated, cultured in vitro, and identified by flow cytometry. A CGRP recombinant lentivirus wa...

MicroRNA (miRNA) has been proved to play a key role in lipid metabolism. In our previous study, miR-125b was validated to be differentially expressed in preadipocytes and adipocytes, which was also proved to involve in lipid metabolism. To explore the comprehensive targets of miR-125b in adipocytes, isobaric tag for relative and absolute quantitation (iTRAQ) analysis was performed to obtain differentially expressed proteins in adipocytes comparing negative control (NC) and miR-125b mimic, combin...

LncRNA TUG1 has the potential to promote the osteogenic differentiation of several cells, but the role of lncRNA TUG1 in osteogenic differentiation of tendon stem/progenitor cells (TSPCs) is still unknown. This study aims to determine the role of lncRNA TUG1 in osteogenic differentiation of TSPCs. bFGF, RUNX2, and Osterix protein expressions were detected by western blot. LncRNA TUG1 and bFGF expression was detected by qRT-PCR. RNA immunoprecipitation (RIP) assay was used to confirm the interact...

Lately, stem cell approaches have provided new information on reproductive organ function and additionally recommended novel treatment possibilities. The type(s) and differentiation potential of stem cells present in the mammalian ovary are largely unknown; while oogonial stem cells have been reported, we explored the possibility that multipotent stem cells may reside in the ovary and have wide differentiation potential. In this experimental study, homogenates of whole mouse ovaries were sorted ...

Cigarette smoke exposure is one of the main etiologies for chronic obstructive pulmonary disease. Moreover, cigarette smoke participates in disease progression by inducing abnormal macrophage polarization; however, the effects of cigarette smoke on M1/M2 macrophage polarization have not been established. The aim of the current study was to determine the effects of cigarette smoke extract (CSE) on M1/M2 macrophage polarization in alveolar and peritoneal macrophages (AM and PM, respectively) at di...
