Embryonic stem cell factors-OCT4, NANOG, and SOX2-contribute to the maintenance of stem cell properties and malignant progression in various cancers, including glioblastoma. Although functional roles of each of these genes are well documented in stem cell and cancer biology, no study has directly compared their cellular transforming activity under same experimental conditions. In this study, we compared the cellular transforming activity of OCT4, NANOG, and SOX2 using human immortalized astrocytes cultured under serum-free stem cell culture conditions...

microRNAs (miR) can potentially be used for categorizing the various subtypes of colorectal cancer (CRC) and predicting a patient's response to treatment with traditional anti-CRC therapies. We investigated how miR-1297 and its potential target molecule cyclin D2 (CCND2) might affect the progression of CRC. Thirty-two pairs of CRC specimens and corresponding samples of para-tumor tissue were collected and examined for their levels of miR-1297 and CCND2 expression. We also examined miR-1297 and CCND2 expression in cultured SW480 cells...

Myocardial fibrosis is a characteristic feature of cardiomyopathies. However, no effective strategies to attenuate cardiac fibrosis are currently available. Late-stage endothelial progenitor cells (EPCs) are precursors of endothelial cells (ECs) that repair the heart through a paracrine mechanism. In the present study, we tested whether EPC-derived exosomes regulate the differentiation of fibroblasts into ECs. We isolated late-stage EPCs from human peripheral blood (PB) and used immunofluorescence and flow cytometry to confirm their identity...

Endothelial-to-mesenchymal transition (EndMT) is a cellular reprogramming mechanism by which endothelial cells acquire a mesenchymal phenotype. EndMT is associated with fibroproliferative diseases, such as cancer progression and metastasis and cardiac and kidney fibrosis, and this condition has been extensively investigated over the past decade. Recently, studies showed that EndMT contributes to the initiation and progression of atherosclerotic lesion and plaque destabilization. Unstable atherosclerotic plaque rupture and subsequent thrombosis are the main pathological causes of acute cardiovascular events...

Nonsmall cell lung cancer (NSCLC) is a type of malignant tumor, accounting for 80% of all lung cancer morbidity. Long noncoding RNA (lncRNA) BLACAT1 (bladder cancer associated transcript 1), also known as linc-UBC1, has been tested to be an oncogenic lncRNA in other cancers. However, the role of BLACAT1 in NSCLC is still unknown. In clinical study, BLACAT1 expression was significantly upregulated in 48 cases of NSCLC tissues compared with adjacent normal tissues, especially in pathological TNM III samples. In NSCLC cells, BLACAT1 expression was also upregulated...

Ovarian theca cells play an indispensable role in ovarian follicular development and hormone secretion. miR-26a-5p was reported to be differentially expressed in mature and immature chicken ovaries in our previous study; however, the role of miR-26a-5p in regulating ovarian follicle function is still unclear. In this study, we demonstrated that the expression dynamics of TNRC6A mRNA in either chicken ovaries or follicles showed an opposite trend compared with that of chicken miR-26a-5p expression. miR-26a-5p inhibited TNRC6A mRNA expression by directly targeting its 3'-untranslated region in cultured chicken theca cells...

Schizophrenic patients tend to have reduced incidence of some cancers due to the treatment of antipsychotic drugs with antitumor effects, such as chlorpromazine and trifluoperazine (TFP). Forkhead Box O1 (FOXO1) as tumor suppressor in many malignancies is often inactivated by nuclear export, which could be inhibited by TFP. However, the antitumor efficiency of TFP and related role of FOXO1 in hepatocellular carcinoma (HCC) are unclear. Thus, two HCC cell lines SMMC-7721 and Bel-7402 were treated with different concentrations of TFP and the IC50 was determined...

Phosphatase and tensin homolog deleted on chromosome ten (PTEN) is a lipid and protein phosphatase and possesses an antitumor effect in lung cancers. miRNAs are reportedly abnormally expressed in human lung cancers. However, whether miRNA contributes to PTEN expression in non-small cell lung cancers (NSCLCs) has not been clearly clarified. In the present study, we found that miR-1297 probably binds with 3'UTR sequence of PTEN and negatively regulated the levels of PTEN in NSCLC cells. First, the expression levels of PTEN and Skp2 were detected by western blotting in NSCLC specimens and paired normal tissue specimens...

Small nucleolar RNA host gene 12 (SNHG12) is a novel long noncoding RNA identified to be upregulated and functions as an oncogene in several cancers. However, the function of SNHG12 and its target genes in modulating nonsmall cell lung cancer (NSCLC) development are rarely reported. In the present study, we validated that SNHG12 was overexpressed, while miR-138 was low-expressed, in NSCLC cells compared with normal human lung epithelial cells. SNHG12 harbored the binding site of miR-138 and inversely regulated the expression miR-138...

Long noncoding RNAs (lncRNAs) have been proved as important regulators in many diseases, including cancers. HOXA11 antisense RNA (HOXA11-AS) is a novel identified lncRNA associated with cancer progression. However, the role of HOXA11-AS in glioma remains poorly understood and needs to be elucidated. The purpose of this study is to investigate the role and regulating mechanism of HOXA11-AS on gliomagenesis. Expression of HOXA11-AS was significantly upregulated in glioma tissue and cell lines compared with the adjacent normal tissue and cells...

The Sertoli cell plays a vital role during the spermatogenesis process and has been identified as one of the main targets of the toxic action of heavy metals on the seminiferous epithelium. In the present work, the effect of lead (Pb), Arsenic (As), and Cadmium (Cd) in primary cultures of Sertoli cells was analyzed by measuring the expression of the genes Cldn11, Ocln, and Gja1 that participate in the tight and gap junctions, which are responsible for maintaining the blood-testis barrier. Sertoli cells were isolated from the testes of Wistar rats...

The enrichment of CD20(+) and CD138(+) immune cells were previously associated with improved survival in colorectal cancer (CRC). We previously discovered that the resected tumors in CRC patients were highly enriched with interleukin (IL)-10-producing CD19(lo)CD27(hi) plasmablasts with potential suppressor functions. It is still unknown what roles the CD19(lo)CD27(hi) plasmablasts play in CRC patients. In this study, we first demonstrated that B cells from peripheral blood mononuclear cells (PBMCs) could be stimulated to resemble tumor-infiltrating plasmablasts using a coculture containing Caco-2 and heat-killed bacteria...

Chemokine receptor 7 (CCR7) has emerged as an inducer of invasion, migration, and epithelial-mesenchymal transition (EMT) in cancer. In this research, human malignant glioma cells were stimulated with transforming growth factor beta 1 (TGF-β1) and siCCR7. The data show that CCR7 mediates TGF-β1-induced EMT, migration, and invasion in U251 and U87 cells and that these effects of TGF-β1 were reversed by treatment with siCCR7 or a CCR7 neutralizing antibody. Importantly, the TGF-β1-mediated increase in nuclear factor kappaB (NF-κB) activity in human glioma cells was reduced by treatment with siCCR7 or a CCR7 neutralizing antibody...

Lymphocyte activation gene-3 (LAG-3) is a CD4 homologue expressed on the surface of activated conventional T cells and regulatory T (Treg) cells. In conventional T cells, LAG-3 acts as an inhibitory receptor of T cell inflammation. However, the role of LAG-3 in Treg cells remains controversial. In this study, we investigated the effect of LAG-3 on Tregs in osteoarthritis (OA). We observed that the proportion of LAG-3-expressing cells in CD4(+)CD25(+/high) T cells and Foxp3(+)CD4(+)CD25(+/high) T cells were significantly upregulated in OA patients...

Long noncoding RNAs (lncRNAs) have been reported to play vital roles in various human cancers. The aim of this study was to explore the critical role of lncRNA HOXA11-AS in uveal melanoma (UM) progression. Briefly, we found that HOXA11-AS is overexpressed in UM tissues and cells; HOXA11-AS could regulate UM cell growth, invasion, and apoptosis. Mechanistically, RNA immunoprecipitation demonstrated that HOXA11-AS could simultaneously interact with enhancer of zeste homolog 2 (EZH2) to suppress its target p21 protein expression...

Osteosarcoma (OS) is a bone malignancy with high incidence. The underlying molecular mechanisms that are associated with the development of OS need further investigation. In this study, we showed that SLC34A2, a member of the solute carrier gene family, was significantly downregulated in OS patients and cell lines. Overexpression of SLC34A2 inhibited the proliferation, migration, and invasion of OS cells. Mechanistically, we found that SLC34A2 interacted with PTEN, and inactivated the PI3K/AKT signaling pathway...
