BACKGROUND: Emerging evidence show that long noncoding RNAs (lncRNAs) are crucial regulators in pathophysiology of acute lung injury (ALI). Small nucleolar RNA host gene 14 (SNHG14) is a novel oncogenic lncRNA, and has been associated with inflammation-related cell injuries. Thus, we wondered the role and mechanism of SNHG14 in lipopolysaccharides (LPS)-induced ALI cell model. METHODS: Expression of SNHG14, miRNA (miR)-124-3p, and transforming growth factor β type 2 receptor (TGFBR2) was detected by RT-qPCR and western blotting...

A growing body of evidence has shown that extracellular vesicles can be efficient as experimental therapeutics in pre-clinical models of skin wounds, but there is a significant unmet need to translate this to clinical utilization. The objectives of the current systematic review were to identify the strength of the therapeutic effects of EVs derived from stem cells in cutaneous wounds and to assess which EV-mediated mechanisms could be involved in the therapeutic response. PubMed, ISI Web of Science, and Scopus databases were systematically searched...

Cell Competition is a selective process by which viable cells are eliminated from developing or adult tissues by interactions with their neighbors. In many cases, the eliminated cells (losers) display reduced fitness, yet they would be able to sustain tissue growth or maintenance in a homotypic environment, and are only eliminated when confronted with surrounding wild type cells (winners). In addition, cells with oncogenic mutations that do not show reduced fitness can also be eliminated from tissues when surrounded by wild type cells...

INTRODUCTION: The goal of regenerative endodontic procedures is to preserve and stimulate stem cells from the apical papilla (SCAPs) to develop the pulp-dentin complex using various growth factors and scaffolds. We hypothesized that treatment of SCAPs with vascular endothelial growth factor (VEGF) or nerve growth factor (NGF) may impact the expression of osteogenic and dentinogenic markers. METHODS: The optimum concentration of VEGF and NGF on SCAP viability was assessed and introduced to SCAPs for 6-24 hours...

Cholangiocarcinoma (CCA) is a variety of biliary epithelial tumors involving intrahepatic, perihilar and distal bile duct. It is the most common malignant bile duct tumor in the liver and the second most common primary liver cancer, whose molecular mechanism not fully understood. Specifically, the relationship between CCA and chondroitin polymerizing factor (CHPF) is still not clear. In this study, detection of clinical specimens was performed to preliminarily study the role of CHPF in CCA. CCA cells with CHPF knockdown were constructed for in vitro study, which was also used in the construction of mice xenograft model for investigating the role of CHPF in the development of CCA...

In non-small cell lung cancer (NSCLC), uncommon epidermal growth factor receptor (EGFR) mutations are mutations other than Ex19 deletion and Ex21 L858R, which are common mutations highly sensitive to EGFR-tyrosine kinase inhibitors. Afatinib, a second-generation EGFR-tyrosine kinase inhibitor, has been shown to be effective in patients with uncommon mutations. Dacomitinib, another second-generation EGFR-tyrosine kinase inhibitor, has not previously been shown to be effective in patients with uncommon mutations...

BACKGROUND: Gliomas are highly aggressive and lack of efficient targeted therapy. YAP, as a Hippo pathway downstream effector, plays a key role in promoting tumor development through the interaction with transcription factor TEAD on the NH3-terminal proline-rich domain. Therefore, targeting TEAD-interacting domain of YAP may provide a novel approach for the treatment of gliomas. MATERIALS AND METHODS: We generated a truncated YAP protein which includes the TEAD-binding domain (YAPBD), and supposed YAPBD can interact with endogenous TEAD but lost the function to activate YAP target gene expressions...

In this study, the association of expressional alterations in neuronal G protein-coupled receptors (GPCRs) with induction of protective response to polystyrene nanoparticles (PS-NPs) was investigated in Caenorhabditis elegans . On the basis of both phenotypic analysis and expression levels, the alterations in expressions of NPR-1, NPR-4, NPR-8, NPR-9, NPR-12, DCAR-1, GTR-1, DOP-2, SER-4, and DAF-37 in neuronal cells mediated the protective response to PS-NPs exposure. In neuronal cells, NPR-9, NPR-12, DCAR-1, and GTR-1 controlled the PS-NPs toxicity by activating or inhibiting JNK-1/JNK MAPK signaling...

Non‑small cell lung cancer (NSCLC) remains an intractable disease, which is primarily due to tumor metastasis and the acquisition of resistance to chemotherapy. Therefore, there is an urgent need for novel therapeutics to overcome these obstacles. It was recently demonstrated that upregulated expression of monoamine oxidase A (MAOA) contributes to the progression of NSCLC. G10, a tumor‑targeting representative conjugate of heptamethine carbocyanine dye and an inhibitor of MAOA, was shown to exert potent cytotoxic effects, comparable to those of doxorubicin, against prostate cancer cell lines, as well as moderate MAOA inhibitory activity...

As a potential oncogene, nucleolar and spindle‑associated protein 1 (NUSAP1) is involved in the regulation of tumor cell proliferation, metastasis and drug resistance. However, the role of NUSAP1 in non‑small cell lung cancer (NSCLC) remains unclear. The present study aimed to investigate the biological function and underlying molecular mechanisms of NUSAP1 in NSCLC. NUSAP1 expression was measured in NSCLC tissues and cell lines via immunohistochemistry and western blotting, respectively. NSCLC cell lines stably inhibiting NUSAP1 were established to investigate its effects on cell proliferation, colony formation and invasion, and on in vivo tumorigenicity...

A synthetic peptide that blocks the interaction between the metastasis‑enhancing calcium‑binding protein, S100A4, and its effector protein, methionine aminopeptidase 2 (MetAP2) (the NBD peptide), was previously demonstrated to inhibit the angiogenesis of endothelial cells, leading to the regression of human prostate cancer in a xenograft model. However, the effects of the NBD peptide on the malignant properties of cancer cells that express S100A4 remain to be elucidated. The present study demonstrates that the NBD peptide inhibits the invasiveness and metastasis of highly metastatic human mammary carcinoma cells...

Intrahepatic cholangiocarcinoma (iCCA) is closely correlated with hepatic progenitor cell (HPC) expansion and liver fibrosis. Brahma-related gene 1 (Brg1), an enzymatic subunit of the SWltch/Sucrose Non-Fermentable (SWI/SNF) complex that is critical in stem cell maintenance and tumor promotion, is prominently up-regulated in both HPCs and iCCA; however, its role in this correlation remains undefined. A retrospective cohort study indicated that high Brg1 expression suggests poor prognosis in iCCA patients. In chronically injured livers induced by a 0...

Desmoid tumors have a variable clinical course that ranges from indolence or spontaneous regression to an aggressive pattern marked by local invasion. Up to half may remain stable or regress; watchful waiting is the preferred approach in the initial management of desmoid tumors. Symptomatic or progressive tumors or those that may affect adjacent critical structures require surgery, radiotherapy, or systemic therapy. Although radiotherapy effectively controls desmoid tumors in most cases, concerns regarding late toxicity exist...

The AT‑rich interacting domain (ARID) family of DNA‑binding proteins is involved in various biological processes, including the regulation of gene expression during cell proliferation, differentiation and development. ARID3A and ARID3B are involved in chromatin remodeling and can bind to E2F1 and retinoblastoma tumor suppressor protein (RB), respectively. However, their role in regulating E2F target gene expression remains poorly understood. E2F transcription factors are critical regulators of cell cycle progression and are modulated by RB...

Circular RNAs (circRNAs) are a class of non‑coding RNAs formed by covalently closed loops through back‑splicing and exon‑skipping. circRNAs have been confirmed to play a vital role in various biological functions, acting as microRNA sponges and reservoirs, as well as combining with RNA‑binding proteins during the progression of multiple cancer types. Therefore, the present review evaluated recent research articles in PubMed that were published between November 2017 and September 2020. Key word search strings included: 'Circular RNA (circRNA) AND bladder cancer (BC)', 'circular RNA (circRNA) AND prostate cancer (PCa)' and 'circular RNA (circRNA) AND renal cell cancer (RCC)'...

Breast cancer (BC) is one of the most common malignant tumours in women. The matrix metalloproteinase (MMP) enzyme family plays a complex role in the development of BC. There is increasing evidence that MMP11 plays a major role in BC; however, the underlying mechanisms are not clear. The present study confirmed by analysing clinical samples and TCGA data sets, that high expression of MMP11 in clinical samples of BC was strongly associated with a poor prognosis in BC patients. In addition, MTT and colony formation assays indicated that the proliferative capacity of BC was affected when MMP11 expression changed...

Nerve growth factor (NGF), a prototypical neurotrophic factor essential for neuronal cell proliferation and survival, has been implicated as a marker of tumor progression, as well as a potential target for novel therapeutic approaches in cancer. To investigate the functional potential of NGF in liver cancer in the present study, a stable NGF‑overexpressing HepG2 cell line was generated. The scratch‑wound assay was used to investigate cell motility and polarity. Western blotting was performed to evaluate the expression levels of epithelial‑mesenchymal transition (EMT)‑related proteins, including E‑cadherin, N‑cadherin and vimentin...
