Transcriptome analysis was carried out for wheat seedlings and spikes from hybrid Jingmai 8 and both inbred lines to unravel mechanisms underlying heterosis. Heterosis, known as one of the most successful strategies for increasing crop yield, has been widely exploited in plant breeding systems. Despite its great importance, the molecular mechanism underlying heterosis remains elusive. In the present study, RNA sequencing (RNA-seq) was performed on the seedling and spike tissues of the wheat (Triticum aestivum) hybrid Jingmai 8 (JM8) and its homozygous parents to unravel the underlying mechanisms of wheat heterosis...

AIMS: Diabetic nephropathy (DN) is the most common microvascular complications and the principal cause of mortality and morbidity in patients with diabetes. The expression of advanced oxidation protein products (AOPPs) has been found in vacuolated renal tubules in DN and correlated with patients' decreased renal function. The accumulation of AOPPs is regarded as an initiating factor in podocyte injuries via the protein kinase C (PKC) signaling, which plays a critical role in triggering oxidative stress and mitochondrial injuries in diseases including DN...

Tubulointerstitial fibrosis (TIF) is the hallmark of chronic kidney disease and best predictor of renal survival. Many different cell types contribute to TIF progression including tubular epithelial cells, myofibroblasts, endothelia, and inflammatory cells. Previously, most of the attention has centered on myofibroblasts given their central importance in extracellular matrix production. However, emerging data focuses on how the response of the proximal tubule, a specialized epithelial segment vulnerable to injury, plays a central role in TIF progression...

Tubulointerstitial fibrosis (TIF) is a pivotal pathophysiological process in patients with diabetic nephropathy (DN). Multiple profibrotic factors and cell types, including transforming growth factor beta 1 (TGF-β1) and interstitial myofibroblasts, respectively, are responsible for the accumulation of extracellular matrix in the kidney. Matrix-producing myofibroblasts can originate from different sources and different mechanisms are involved in the activation process of the myofibroblasts in the fibrotic kidney...

Tubulointerstitial fibrosis (TIF) is crucial in the development of renal fibrosis in diabetic nephropathy(DN). Previous data shows that SIRT1 plays an important role on fibrosis, but the effect on TIF in DN and underlying mechanisms remains uncertain. In this study, we evaluated the vital role of SIRT1 and identified SIRT1 as a downstream target gene of microRNA-34a-5p (miR-34a-5p) in TIF of DN. The result revealed that expression of miR-34a-5p, fibronectin(FN),collagen type I (COL1) and transforming growth factor β1 (TGF-β1) were up-regulated accompanied by the corresponding down-regulation of SIRT1 in renal tissues of high fat diet and streptozotocin(HFD/STZ)induced diabetic mice with DN, and that the SIRT1 mRNA level was negatively correlated with miR-34a-5p expression in high glucose stimulated human proximal tubule cell line(HK-2) cells...

Combining endurance training with resistance training (RT) may attenuate skeletal muscle hypertrophic adaptation versus RT alone; however, the underlying mechanisms are unclear. We investigated changes in markers of ribosome biogenesis, a process linked with skeletal muscle hypertrophy, following concurrent training versus RT alone. Twenty-three males underwent eight weeks of RT, either performed alone (RT group, n = 8), or combined with either high-intensity interval training (HIT+RT group, n = 8), or moderate-intensity continuous training (MICT+RT group, n = 7)...

Context Hemorrhage is one of the potentially fatal complications of tracheostomy. A rare but lethal cause of tracheostomy related bleeding is hemorrhage from the innominate artery. This occurs following tracheo-innominate artery fistula (TIF) formation, which is associated with a mortality rate of more than 85%. Here, we report the case of an individual with tetraplegia and a tracheostomy who died as a result of innominate artery hemorrhage. This case highlights the possible causes and interventions associated with this complication, and provides insight into tracheostomy related bleeding in patients with spinal cord injury (SCI)...

BACKGROUND & AIMS: The effects of transoral incisionless fundoplication (TIF) and laparoscopic Nissen fundoplication (LNF) have been compared with those of proton pump inhibitors (PPIs) or a sham procedure in patients with gastroesophageal reflux disease (GERD), but there has been no direct comparison of TIF vs LNF. We performed a systematic review and network meta-analysis of randomized controlled trials to compare the relative efficacies of TIF vs LNF in patients with GERD. METHODS: We searched publication databases and conference abstracts through May 10, 2017 for randomized controlled trials that compared the efficacy of TIF or LNF with that of a sham procedure or PPIs in patients with GERD...

Previously our lab has created a mouse ovarian xenograft model of copy number variation (CNV)-mediated G protein-coupled receptor (GPCR) MAS-driven tumorigenesis, and RNA profiling identified a putative chemokine tumor-induced factor (Tif). Sequence analysis and chemotactic study suggested that Tif was likely to be a hamster homolog of human GROγ (CXCL3) [IJC 125 (2009): 1316-1327]. In the present study, we report the molecular and functional characterization of the Tif gene. Genomic study of CHO-K1 cells indicated that Tif gene consisted of 4 exons, characterized with an antisense B1 element which is embedded in the fourth exon...

Extracellular matrix deposition during tubulointerstitial fibrosis (TIF), a central pathological process in patients with diabetic nephropathy (DN), is driven by locally activated, disease-relevant myofibroblasts. Myofibroblasts can arise from various cellular sources, e.g., tubular epithelial cells via a process named epithelial-to-mesenchymal transition (EMT). Transforming growth factor beta 1 (TGF-β1) and its downstream Smad signaling play a critical role in both TIF and EMT. Whereas Smad3 is one central mediator, the role of the other prominently expressed variant, Smad2, is not completely understood...
