Chronic hypoxia frequently complicates the care of patients with interstitial lung disease, contributing to the development of pulmonary hypertension (PH), and premature death. Connective tissue growth factor (CTGF), a matricellular protein of the Cyr61/CTGF/Nov (CCN) family, is known to exacerbate vascular remodeling within the lung. We have previously demonstrated that vascular endothelial-cell specific down-regulation of CTGF is associated with protection against the development of PH associated with hypoxia, though the mechanism for this effect is unknown...

Long non-coding RNA (lnc)TCF7 has been reported to promote the self‑renewal of human cancer stem cells, and enhance the aggressiveness of human non‑small cell lung cancer and hepatocellular carcinoma cells. However, the effect of lncTCF7 on colorectal cancer (CRC) tumorigenesis and progression is currently unclear. In the present study, reverse transcription‑quantitative polymerase chain reaction results demonstrated that lncTCF7 expression was higher in CRC tissues compared with adjacent normal tissues and was significantly associated with tumor size, differentiation degree, tumor‑node‑metastasis grade, lymph node metastasis and invasion depth...

BACKGROUND Carbon ion radiotherapy has been shown to be more effective in cancer radiotherapy than photon irradiation. Influence of carbon ion radiation on cancer microenvironment is very important for the outcomes of radiotherapy. Tumor-infiltrating dendritic cells (DCs) play critical roles in cancer antigen processing and antitumor immunity. However, there is scant literature covering the effects of carbon ion radiation on DCs. In this study, we aimed to uncover the impact of carbon ion irradiation on bone marrow derived DCs...

Accumulating evidence from neuroimaging studies suggests that primary insomnia (PI) affects interregional neural coordination of multiple interacting functional brain networks. However, a complete understanding of the whole-brain network organization from a system-level perspective in PI is still lacking. To this end, we investigated in topological organization changes in brain functional networks in PI. 36 PI patients and 38 age-, sex-, and education-matched healthy controls were recruited. All participants underwent a series of neuropsychological assessments and resting-state functional magnetic resonance imaging scans...

Circular RNAs (circRNAs) participate in the pathogenesis of various diseases by sponging microRNAs (miRs). However, the roles of circRNAs remain unreported in glomerular diseases. We previously reported that miR-150 positively correlated with renal chronicity index in patients with lupus nephritis (LN). We aimed to investigate renal circRNA profiling and the interaction between circRNAs and miR-150 in LN patients. Six renal biopsies from untreated female patients with LN class IV and five normal kidney tissues from urology patients were used for circRNA sequencing...

Patients with diabetes are at higher risk of developing carotid artery stenosis and resultant stroke. Arachidonoyl phospholipids affect plaque inflammation and vulnerability, but whether diabetic patients have unique carotid artery phospholipidomic profiles is unknown. We performed a comprehensive paired analysis of phospholipids in extracranial carotid endarterectomy (CEA) plaques of matched diabetic and nondiabetic patients and analyzed mass spectrometry-derived profiles of three phospholipids - plasmenyl-phosphatidylethanolamine (pPE), phosphatidylserine (PS), and phosphatidylinositol (PI) - in minimally diseased (MIN) and maximally diseased (MAX) CEA segments...

MicroRNAs (miRNAs) are endogenous ∼22 nt noncoding RNAs that control the translation initiation and stability of target genes in a sequence-specific manner and, thus, play important regulatory roles in animals and plants. Homologs of Dom34, called Pelota or PELO, are broadly conserved in eukaryotes and archaea. Biochemical and genetic studies indicate that eukaryotic Dom34/Pelota plays an important role in cell division, differentiation of germline stem cells, and stem cell self-renewal by controlling the expression of specific genes at the translational level...

Macrophages are a major component of the immune system and play an important role in regulating the magnitude, duration, and quality of the inflammatory response. Dissecting the functions of transcription factors regulating macrophage activation is important for understanding the inflammatory responses. Nuclear factor erythroid 2 like 1 (NFE2L1, also known as Nrf1) is a CNC-bZIP protein, which has multiple isoforms. While the exact physiological functions of various isoforms of NFE2L1 are still under investigation, accumulating evidence indicate that long isoforms of NFE2L1 (NFE2L1(L)) are important regulators in the antioxidant response, proteasome homeostasis and inflammation...

Previous neuroimaging studies have reported brain morphological alterations and the occurrence of mental disorders in primary insomnia (PI) patients. However, studies of the effect of disrupted sleep on brain structure have showed inconsistent results. In this study, DARTEL-VBM was used to evaluate the changes in gray matter volume from 60 PI patients and 53 controls. Voxel-wise statistics was performed in two ways. One is a more liberal statistical analysis using an uncorrected P < 0. 001 with 25 voxels, and the other one is a more conservative approach using a threshold of P < 0...

Abdominal wall defects are a common medical problem, and inadequate repair methods can lead to serious complications. Abdominal wall reconstruction using autologous tissue, or non-biological, biological, or composite patches is often performed to repair defective areas. In particular, composite patches containing both polymeric and biological materials have gained increasing attention due to their good mechanical properties and biocompatibility. However, it is still unclear whether the quality of repairs using composite patches is superior to that of a biological patch...

Infection with cagA-positive Helicobacter pylori is associated with a higher risk of gastric cancer. The cagA gene product, CagA, is translocated into gastric epithelial cells and perturbs host cellular biological functions. Etoposide, a topoisomerase II inhibitor widely used to couple DNA damage to apoptosis, is a common cytotoxic agent used for advanced gastric cancer. We investigate the effect of CagA on etoposide-induced apoptosis in gastric cancer cells to elucidate whether CagA play a role in gastric carcinogenesis via impairing DNA damage-dependent apoptosis...

The transport of LDL-derived cholesterol from lysosomes to peroxisomes is mediated by membrane contacts, which are facilitated by the lysosomal protein synaptotagmin VII and the peroxisomal lipid phosphatidylinositol 4, 5-bisphosphate (PI(4,5)P2). Here, we used RNA interference to search for regulators of PI(4,5)P2 and to study the effects of altered PI(4,5)P2 homeostasis on cholesterol transport. We found that knockdown of phosphatidylinositol 5-phosphate 4-kinase type-2 alpha (PIP4K2A) reduced peroxisomal PI(4,5)P2 levels, decreased lysosome-peroxisome membrane contacts, and increased accumulation of lysosomal cholesterol in human SV-589 fibroblasts...
