The zebrafish genome encodes homologs for most of the proteins involved in inflammatory pathways; however, the molecular components and activation mechanisms of fish inflammasomes are largely unknown. ASC (apoptosis-associated speck-like protein containing a caspase-recruitment domain (CARD)) is the only adaptor involved in the formation of multiple types of inflammasomes. Here, we demonstrate that zASC is also involved in inflammasome activation in zebrafish. When overexpressed in vitro and in vivo in zebrafish, both the zASC and zASC pyrin domain (PYD) proteins form speck and filament structures...

INTRODUCTION: Hamstring injuries remain a significant burden in sports that involve high speed running. In elite male football, hamstring injury has repeatedly been identified as the most common noncontact injury, representing 12% of all injuries. As the incidence remains high, investigations are aimed at better understanding how to improve prevention efforts. Intrinsic risk factors such as strength have been investigated extensively in a cohort of professional football players; however, other intrinsic measures of neuromuscular function have not been studied in this cohort...

BACKGROUND: Tumour metastasis has been associated with cancer stem cells, a small population with stem-like cells properties, higher rate of migration and metastatic potential compared to cells from the tumour bulk. Our aim was to evaluate the immunoexpression of the putative cancer stem cell biomarkers ALDH1 and CD44 in primary tumour and corresponding metastatic lymph nodes. METHODS: Tumour tissue specimens (n=50) and corresponding metastatic lymph nodes (n=25) were surgically obtained from 50 patients with oral squamous cell carcinoma and submitted to immunohistochemistry...

OBJECTIVE: To build-up a nomogram able to predict treatment success after Collagenase clostridium histolyticum (CCH) for Peyronie's disease (PD). MATERIAL AND METHODS: From November 2016 to November 2017, we enrolled 135 patients with PD in a multicentre single-arm prospective study. All patients enrolled had a treatment with CCH. Success of therapy was defined as a penile curvature decrease of at least 20 degrees from baseline curvature. Treatment satisfaction was assessed using a scale from 1 to 10 and high satisfaction was arbitral defined as a score ≥8...

Recent acute studies have shown that high-intensity resistance circuit-based (HRC) training in hypoxia increases metabolic stress. However, no intervention studies have yet proven their effectiveness. This study aimed to analyse the effect of 8 weeks of HRC in hypoxia on aerobic performance, resting energy expenditure (REE), repeat sprint ability (RSA) and haematological variables. Twenty-eight subjects were assigned to hypoxia (FiO2 =15%; HRChyp : n=15; age: 24.6±6.8 years; height: 177.4±5.9 cm; weight: 74...

The Microgastrinae are a hugely diverse subfamily of endoparasitoid wasps of lepidopteran caterpillars. They are important in agriculture as biological control agents, and play a significant ecological role in the regulation of caterpillar populations. Whilst the group has been the focus of intensive rearing and DNA barcoding studies in the Northern Hemisphere, the Australian fauna has received little attention. In total, 100 species have been described from or have been introduced into Australia, but the real species diversity for the region is clearly much larger than this...

Exome capture is an effective tool for surveying the genome for loci under selection. However, traditional methods require annotated genomic resources. Here, we present a method for creating cDNA probes from expressed mRNA, which are then used to enrich and capture genomic DNA for exon regions. This approach, called "EecSeq", eliminates the need for costly probe design and synthesis. We tested EecSeq in the eastern oyster, Crassostrea virginica, using a controlled exposure experiment. Four adult oysters were heat shocked at 36° C for 1 hour along with four control oysters kept at 14° C...

Defining a common and specific functions for homologs of a novel protein family is not a trivial task. In their recent study, Tomkins and colleagues have addressed this challenge for the ROCO protein family by exploring interactomes of its four human members: MASL1, DAPK1, LRRK1 and LRRK2. ROCO proteins are characterized by a Ras-GTPase domain embedded in complex multidomain proteins and a functional descriptor for this protein family has been elusive despite accumulating research, particularly for LRRK2, a protein implicated in Parkinson's disease...

AIMS: Skeletal muscle lipid stores and mitochondrial function have been appointed as key players in obesity-induced insulin resistance. However, there are conflicting reports in the literature based on in vitro quantitative measurements. Here we test the hypothesis that it is not the quantity but the quality that matters. METHODS: The present study combines quantitative and qualitative structural measurements of lipid stores and mitochondrial dynamics in skeletal muscle from lean subjects, and subjects with morbid obesity, with and without type 2 diabetes, before and after gastric bypass surgery...

AIM: In acute kidney injury (AKI) regions of the kidney are hypoxic. However, for reasons yet unknown, adaptation to hypoxia through hypoxia inducible factor (HIF) is limited. Here we studied miR-22, a potential HIF repressor, in normal kidneys, as well as in rhabdomyolysis-induced AKI, a condition where miR-22 is up-regulated. METHODS: AKI in mice was provoked by IM injection of glycerol. Tissue homogenates were processed to determine the levels of candidate RNAs and proteins, as well as global gene expression profiles...

REVIEW
Annika Hantusch, Markus Rehm, Thomas Brunner
The Bcl-2 protein family members critically regulate mitochondrial outer membrane permeabilization (MOMP), a point-of-no-return in the intrinsic and extrinsic apoptosis pathways. The common view on qualitative interaction and activation patterns of the three subclasses, the BH3-only proteins, prosurvivals and effectors, is static and currently being revolutionized by an emerging understanding of the complex dynamic equilibria that govern cellular fate. Recent experimental evidence on protein associations with the mitochondrial outer membrane, retrotranslocation to the cytosol and differential binding affinities in aqueous and membranous environments instigate the development of a revised model of Bcl-2 family interplay...

Human apolipoprotein (apo) C-II is one of several plasma apolipoproteins that form amyloid deposits in vivo and is an independent risk factor for cardiovascular disease. Lipid-free apoC-II readily self-assembles into twisted-ribbon amyloid fibrils but forms straight, rod-like amyloid fibrils in the presence of low concentrations of micellar phospholipids. Charge mutations exerted significantly different effects on rod-like fibril formation compared to their effects on twisted-ribbon fibril formation. For instance, the double mutant K30D, D69K apoC-II readily formed twisted-ribbon fibrils, while the rate of rod-like fibril formation in the presence of micellar phospholipid was negligible...

The exact physiological role for the monoamine serotonin (5-HT) in modulation of insulin secretion is yet to be fully understood. Although the presence of this monoamine in islets of Langerhans is well established, it is only with recent advances that the complex signaling network in islets involving 5-HT is being unraveled. With more than fourteen different 5-HT receptors expressed in human islets, and receptor independent mechanisms in insulin producing β-cells, our understanding of 5-HT's regulation of insulin secretion is increasing...

It seems logical that the composition of the vaginal microbiota would be a significant variable influencing pregnancy outcome. Bacteria that are not part of the normal microbiota can trigger induction of myometrial contractions and premature delivery. Components of the endogenous microbiome may also be capable, under conditions still ill-defined, of interfering with pregnancy progression. This article is protected by copyright.
