Esophageal squamous cell carcinoma (ESCC) is widely regarded as one of the most lethal types of cancer around the world. The fact that early detection of ESCC could dramatically improve the treatment outcome of the patients has sparked considerable interest in searching for reliable and accurate diagnostic biomarkers. Recently, circular RNAs (circRNA) have emerged as a new type of non-coding RNAs with significant RNase resistance, wide abundance and remarkable internal diversity. There is also increasing evidence suggesting that circRNAs could be implicated in the pathogenesis of cancer and other diseases...

T-helper 17 (Th17) cells produce Interleukin-17 (IL-17) that plays an important role in host-defense. However, little is known whether aging affects the functions of human Th17 cells. In this study, we examine age-associated alteration in Th17-cell response; correlation between Th17-cells and endothelial cell senescence; and the occurrence of acute cerebral infarction (ACI). First, we examined Th17-frequency, phenotyping, key transcription factors, and relevant cytokines in healthy elderly, middle-aged and young-people along with elderly-patients with ACI...

Triptolide is known to have a strong anti-proteinuric effect through direct protection of podocytes from injury and is used to treat glomerular diseases. However, the mechanism underlying its protective effect on podocytes remains elusive. MiR-30 family has recently been shown to be essential for structural and functional homeostasis of podocytes but is downregulated by injurious factors, leading to podocyte injury. In the present study, we explore whether Triptolide protects podocytes through preventing miR-30 downregulation...

Type 1 diabetes mellitus (T1DM) is an autoimmune disease due to progressive injury of islet cells mediated by T lymphocytes (T cells). Our previous studies have shown that only cathepsin G (CatG), not other proteases, is involved in the antigen presentation of proinsulin, and if the presentation is inhibited, the activation of CD4+ T cells induced by proinsulin is alleviated in T1DM patients, and CatG-specific inhibitor reduces the activation of CD4+ cells induced by proinsulin in T1DM patients. Therefore, we hypothesize that CatG may play an important role in the activation of CD4+ T cells in T1DM...

This study tested the hypothesis that extracorporeal shock wave (ECSW) therapy could protect mouse brain from chronic cerebral hypoperfusion (CHP)-induced neuropathological changes in a bilateral carotid arterial stenosis (CAS) model. Adult-male C57BL/6 (B6) mice (n=36) were randomized into group 1 (sham-control), group 2 (CHP) and group 3 [CHP+ECSW (100 impulses at 0.15 mJ/mm2) on day 5, 10 and 15 after CHP induction]. By day 60 after CHP induction, the white matter lesion, protein expressions of inflammatory (TNF-α/NF-κB/iNOS), oxidative-stress (NOX-1/NOX-2/NOX-4/nitrotyrosine), angiogenesis (eNOS/CD31), apoptotic (Bax/caspase-3/PARP), fibrotic (Smad3/TGF-ß) and mitochondrial-damaged (cytosolic cytochrome-C) biomarkers were significantly higher in group 2 than in groups 1 and 3, and significantly higher in group 3 than in group 1, whereas the protein expressions of anti-apoptotic (Bcl-2), anti-fibrotic (BMP-2/Smad1/5), and mitochondrial-integrity (mitochondrial cytochrome-C) biomarkers showed an opposite pattern to inflammation among the three groups (all P<0...

Mesenchymal stem cells (MSCs) provide promising applications for clinical treatments. However, patients often take medications that affect the viability of transplanted MSCs. The aim of this study was to assess the effects and underlying mechanism of action of aspirin on the proliferation of MSCs. We showed that aspirin inhibited the growth of MSCs in a concentration- and time-dependent manner. Analysis of cell-cycle distributions showed significantly increased cell populations in the G0/G1 phase and decreased cell populations in the S phase and G2/M phase with increasing concentrations of aspirin...

One of the features for pancreatic cancer is that it is often resistant to chemotherapy treatment, which is one of the major hindrances in the treatment of this malignancy. Previous studies indicated that the microRNAs (miRNAs) could mediate resistance of tumor cells to chemotherapy drug in the cancer progression. In the present study, we are aimed to examine whether microRNA-429 was involved in mediating the chemo-resistance of pancreatic cancer cells to gemcitabine. Firstly, a gemcitabine-resistant pancreatic cancer cell line (SW1990/GZ) derived from cell line (SW1990) was constructed and found to possess a decreased expression of miR-429 when it is compared to the original cell line...

DNER, Delta/Notch-like epidermal growth factor (EGF)-related receptor, is a neuron-specific transmembrane protein carrying extracellular EGF-like repeats. The function of DNER in prostate cancer has not been evaluated. Here, we showed that the upregulation of DNER is observed in various cancers, including prostate cancer. Knockdown of DNER in PC-3 cells inhibited cell proliferation, migration and invasion as well as tumorigenesis in PC-3 xenografts. DNER knockdown specifically inhibited cell growth in spheroids...

Staphylococcus aureus (S. aureus) peptidoglycan (PGN-sa), the major cell wall component of S. aureus, has been demonstrated to be an important virulence factor in the pathogenesis of S. aureus-induced osteomyelitis. However, the exact role of PGN-sa in osteoclastogenesis during S. aureus-induced osteomyelitis and its underlying molecular mechanisms remain unclear. In this study, we found that PGN-sa promoted receptor activator of nuclear factor-κB (NF-κB) ligand (RANKL)-induced osteoclast formation. Quantitative real-time polymerase chain reaction results showed that the mRNA expression of osteoclast-specific marker genes, including tartrate-resistant acid phosphatase, cathepsin K, matrix metalloproteinase-9, and calcitonin receptor was upregulated by PGN-sa treatment...

Gliomas are one the most prevalent malignant carcinomas of the central nervous system, and angiogenesis plays a critical role in the progression of these blood vessel-rich tumors. HOTAIR, a long non-coding RNA (lncRNA), acts as an oncogene in gliomas; however, its role in glioma angiogenesis remains unclear. In the present study, we identified a pro-angiogenic activity of HOTAIR. Silencing HOTAIR inhibited glioma-induced endothelial cell proliferation, migration, and tube formation. Further studies showed that vascular endothelial growth factor A (VEGFA) was involved in the HOTAIR-induced glioma angiogenesis...

Growing evidence indicates that miR-106a is involved in tumor growth and metastasis of cancers, but the participation of miR-106a in endometrial adenocarcinoma (EC) is not clear. BCL2L11 is a member of the BCL-2 family and is located in the outer membrane of mitochondria, where this protein acts as a key regulator of excitotoxic apoptosis, apoptosis-inducing factor translocation, and mitochondrial depolarization. To identify a novel therapeutic target in EC, we studied the roles of miR-106a in the proliferation, apoptosis, and metastasis of EC...
