Mutations in canonical transient receptor potential-6 (TRPC6) channels give rise to rare familial forms of focal and segmental glomerulosclerosis (FSGS). Here we examined a possible role for TRPC6 in the progression of chronic puromycin aminonucleoside (PAN) nephrosis in Sprague-Dawley rats, a classic model of acquired nephrotic syndromes. We used CRISPR/Cas9 technology to delete a 239-bp region within exon 2 of the Trpc6 gene (Trpc6del allele). Trpc6del/del rats expressed detectable Trpc6 transcripts missing exon 2, and TRPC6 proteins could be detected by immunoblot of renal cortex...

Primary hyperoxaluria type 1 is a severe kidney stone disease caused by abnormalities of the peroxisomal alanine-glyoxylate aminotransferase (AGT). The most frequent mutation G170R results in aberrant mitochondrial localization of the active enzyme. To evaluate the population of peroxisome-localized AGT, we developed a quantitative Glow-AGT assay based on the self-assembly split-GFP approach and used it to identify drugs that can correct mislocalization of the mutant protein. In line with previous reports, the Glow-AGT assay showed that mitochondrial transport inhibitors DECA and monensin increased peroxisomal localization of the mutant...

The cystic fibrosis transmembrane conductance regulator (CFTR) is linked to cell apoptosis and abundantly expressed in brain tissue. Mitochondrial oxidative stress plays a key role in activating apoptotic pathway following cerebral ischemia reperfusion (IR) injury. Reduced glutathione (GSH) is exclusively synthesized in cytosol but distributed in mitochondria. In the present study, we investigated whether CFTR affected mitochondrial oxidative stress via regulating GSH and thereby protected neurons against apoptosis following cerebral IR...

REVIEW
Alexander T Mikhailov, Mario Torrado
There is growing evidence that putative gene regulatory networks including cardio-enriched transcription factors, such as PITX2, TBX5, ZFHX3, and SHOX2, and their effector/target genes along with downstream non-coding RNAs can play a potentially important role in the process of adaptive and maladaptive atrial rhythm remodeling. In turn, expression of atrial fibrillation-associated transcription factors is under the control of upstream regulatory non-coding RNAs. This review broadly explores gene regulatory mechanisms associated with susceptibility to atrial fibrillation-with key examples from both animal models and patients-within the context of both cardiac transcription factors and non-coding RNAs...

Elevated LRP16 expression is associated with poor clinical outcomes in multiple malignancies. We detected LRP16 expression in hepatocellular carcinoma (HCC) and found that it was downregulated in tumor samples and HCC cell lines. In a cohort of 80 HCC patients, high level of LRP16 expression in HCC tumors was associated with well differentiation, less lymph node metastasis, and good overall survival (OS). Overexpression of LRP16 in the HepG2 and MHCC-97L cell lines increased cell apoptosis, attenuated cell proliferation, migration, and invasion ability in vitro, and drastically diminished tumor growth and metastasis in vivo...

The RANK (receptor activator of nuclear factor κB)/RANKL (RANK ligand)/OPG (osteoprotegerin) axis is activated after myocardial infarction (MI), but its pathophysiological role is not well understood. Here, we investigated how global and cell compartment-selective inhibition of RANKL affects cardiac function and remodeling after MI in mice. Global RANKL inhibition was achieved by treatment of human RANKL knock-in (huRANKL-KI) mice with the monoclonal antibody AMG161. huRANKL-KI mice express a chimeric RANKL protein wherein part of the RANKL molecule is humanized...

Candida albicans belongs to the normal microbial flora on epithelial surfaces of humans. However, under certain, still not fully understood conditions, it can become pathogenic and cause a spectrum of diseases, from local infections to life-threatening septicemia. We investigated a panel of antimicrobial proteins and peptides (AMPs), potentially involved in mucosal immunity against this pathogen. Out of six studied AMPs, psoriasin was most up-regulated during a mucosal infection, an acute episode of recurrent Candida vulvovaginitis, although candidacidal activity has not been demonstrated...

Inflammation mediated by activated T cells plays an important role in the initiation and progression of hyperhomocysteinemia (HHcy)-accelerated atherosclerosis in ApoE-/- mice. Homocysteine (Hcy) activates T cells to secrete proinflammatory cytokines, especially interferon (IFN)-γ; however, the precise mechanisms remain unclear. Metabolic reprogramming is critical for T cell inflammatory activation and effector functions. Our previous study demonstrated that Hcy regulates T cell mitochondrial reprogramming by enhancing endoplasmic reticulum (ER)-mitochondria coupling...

A human cell is a precisely regulated system that relies on the complex interaction of molecules. Structural insights into the cellular machinery at the atomic level allow us to understand the underlying regulatory mechanism and provide us with a roadmap for the development of novel drugs to fight diseases. Facilitated by recent technological breakthroughs, the Nobel prize-winning technique electron cryomicroscopy (cryo-EM) has become a versatile and extremely powerful tool to solve routinely near-atomic resolution three-dimensional protein structures...

Renal anti-aging protein Klotho exhibits impressive properties of anti-inflammation and renal protection, however is suppressed early after renal injury, making Klotho restoration an attractive strategy of treating renal inflammatory disorders. Here, we reported that Klotho is enriched in macrophages and Klotho preservation by Rhein, an anthraquinone derived from medicinal plant rhubarb, attenuates lipopolysaccharide (LPS)-induced acute inflammation essentially via promoting toll-like receptor 4 (TLR4) degradation...

Development of portal hypertension (PHT) is a central prognostic factor in patients with cirrhosis. Circulating microparticles (MPs) are released by hepatocytes in a caspase-dependent manner, are increased in circulation of patients with cirrhosis, and contribute to PHT via induction of impaired vasoconstrictor responses. Here, we tested the hypothesis that emricasan, a pan-caspase inhibitor, ameliorates PHT and reduction in release of MPs. We used a short-term and long-term protocol following common bile-duct ligation (BDL) in C57BL/6 mice (10 and 20 days, respectively)...

We investigated whether genomic scar signatures associated with homologous recombination deficiency (HRD), which include telomeric allelic imbalance (TAI), large-scale transition (LST), and loss of heterozygosity (LOH), can predict clinical outcomes in patients with ovarian clear cell carcinoma (OCCC). We enrolled patients with OCCC (n = 80) and high-grade serous carcinoma (HGSC; n = 92) subjected to primary cytoreductive surgery, most of whom received platinum-based adjuvant chemotherapy. Genomic scar signatures based on genome-wide copy number data were determined in all participants and investigated in relation to prognosis...

Cell division cycle 7 (Cdc7) plays important roles in the regulation of the initiation of DNA replication throughout S phase. Whether inhibition of Cdc7 has a direct antitumour effect in oral squamous cell carcinoma (OSCC) remains unclear. In this study, XL413, a novel Cdc7 inhibitor, markedly inhibited the viability of OSCC cells but not that of non-tumour primary cells. There was a synergistic effect between XL413 and DNA-damaging agents (e.g. cisplatin and 5-fluorouracil) on OSCC in vitro and in vivo. Moreover, XL413 exhibited a notable antitumour effect on OSCC patients with high Cdc7 expression in mini patient-derived xenografts model...

Human hepatocyte transplantation has been actively perused as an alternative to liver replacement for acute liver failure and liver-based metabolic defects. Current challenges in this field include a limited cell source, reduced cell viability following cryopreservation and poor engraftment of cells into the recipient liver with consequent limited life span. As a result, alternative stem cell sources such as pluripotent stem cells, fibroblasts, hepatic progenitor cells, amniotic epithelial cells and mesenchymal stem/stromal cells (MSCs) can be used to generate induced hepatocyte like cells (HLC) with each technique exhibiting advantages and disadvantages...

This work aims to discuss the possibility that disordered CUL4B was involved in the pathogenesis of adjuvant-induced arthritis (AIA) in rats. Synovium and FLS from AIA rats both showed increased CUL4B and β-catenin, and up-regulated CUL4B enhanced the canonical Wnt signaling by targeting the GSK3β. Increased CUL4B promoted the FLS abnormal proliferation, activated the secretion of IL-1β and IL-8, and promoted the production of AIA pathology gene MMP3 and fibronectin. Furthermore, miR-101-3p was significantly down-regulated in AIA rats compared with controls, and transfection of AIA FLS with miR-101-3p mimics significantly down-regulated the CUL4B expression, whereas transfection with miR-101-3p inhibitors resulted in an opposite observation...

Alterations in the intestinal lymphatic network are pathological processes as related to inflammatory bowel disease (IBD). In this study, we demonstrated that reduction in inflammation-induced lymphangiogenesis ameliorates experimental acute colitis. A soluble and stable angiopoietin-1 (Ang1) variant, COMP-Ang1, possesses anti-inflammatory and angiogenic effects. We investigated the effects of COMP-Ang1 on an experimental colonic inflammation model. Experimental colitis was induced in mice by administering 3% dextran sulfate sodium (DSS) via drinking water...

The lymphatic vasculature act as the drainage system for most of our tissues and organs, clearing interstitial fluid and waste and returning them to the blood circulation. This is not the case for the central nervous system (CNS), which is devoid of parenchymal lymphatic vessels. Nevertheless, the brain is responsible for 25% of the body's metabolism and only compromises 2% of the body's mass. This high metabolic load requires an efficient system to remove waste products and maintain homeostasis. Well-described mechanisms of waste clearance include phagocytic immune cell functions as well as perivascular fluid flow; however, the need for active drainage of waste from the brain is becoming increasingly appreciated...

Chronic pancreatitis leads to irreversible damage in pancreatic endocrine and exocrine functions. However, there is no clinically available antifibrotic drug. Pancreatic stellate cells (PSCs) can be activated by Toll-like receptor 4 (TLR4) responses to its ligands and they contribute to the formation of pancreatic fibrosis. Silencing the expression of TLR4 in PSCs by RNAi may be a novel therapeutic strategy for the treatment of pancreatic fibrosis. In addition, PSCs have a remarkable capacity for vitamin A uptake most likely through cellular retinol binding protein (CRBP)...

Diabetic nephropathy (DN) affects approximately 30-40% of patients with type 1 (T1DM) and type 2 diabetes (T2DM). It is a major cause of end-stage renal disease (ESRD) for the developed world. Hyperglycemia and genetics are major causal factors for the initiation and progression of DN. Multiple abnormalities in glucose and mitochondrial metabolism induced by diabetes likely contribute to the severity of DN. Recent clinical studies in people with extreme duration of T1DM (> 50 years, Joslin Medalist Study) have supported the importance of endogenous protective factors to neutralize the toxic effects of hyperglycemia on renal and other vascular tissues...

We report the role of miR-1187 in regulation of osteoblast functions. Over-expression of miR-1187 inhibited osteoblast differentiation. Target prediction analysis tools and experimental validation by luciferase 3' UTR reporter assay identified BMPR-II and ArhGEF-9 as direct targets of miR-1187. ArhGEF-9 activates Cdc42 which has a major role in actin reorganization. BMP-2 also induces actin polymerization. Role of miR-1187 in actin reorganization was determined by western blotting, immunofluorescence, and in vivo gene silencing studies...
