Fibroblast growth factor receptor 4 (FGFR4) is a member of receptor tyrosine kinase family. A functional Gly388Arg (rs351855 G>A) polymorphism in FGFR4 gene causes a glycine-to-arginine change at codon 388 within the transmembrane domain of the receptor. Although the FGFR4 rs351855 G>A polymorphism has been implicated in cancer development, its association with cancer risk remains controversial. Here, we have systematically analyzed the association between the rs351855 G>A polymorphism and cancer risk by performing a meta-analysis of 27 studies consisting of 8,682 cases and 9,731 controls...

This study aims to investigate the effect of folate deficiency on the male reproductive function and the underlying mechanism. A total of 269 screened participants from 421 recruitments were enrolled in this study. An animal model of folate deficiency was constructed. Folate concentration was measured in the ejaculate, and its association with semen parameters was then determined. The expression and promoter methylation status of ESR1, CAV1, and ELAVL1 were also evaluated. Results showed that seminal plasma folate level was significantly lower among subjects with azoospermia than those with normozoospermia...

BACKGROUND AND AIM: Leukocyte adhesion deficiency type 1 (LAD-I) is a rare, autosomal recessive disorder of neutrophil migration, characterized by severe, recurrent bacterial infections, inadequate pus formation and impaired wound healing. The ITGB2 gene encodes the β2 integrin subunit (CD18) of the leukocyte adhesion cell molecules, and mutations in this gene cause LAD-I. The aim of the current study was to investigate the mutations in patients diagnosed with LAD-I and functional studies of the impact of two previously reported and a novel mutation on the expression of the CD18/CD11a heterodimer...

The CRISPR-Cas9 system has been utilized for large-scale, loss-of-function screens mainly using lentiviral pooled formats and cell-survival phenotypic assays. Screening in an arrayed format expands the types of phenotypic readouts that can be used to now include high-content, morphology-based assays, and with the recent availability of synthetic crRNA libraries, new studies are emerging. Here, we use a cell cycle reporter cell line to perform an arrayed, synthetic crRNA:tracrRNA screen targeting 169 genes (> 600 crRNAs) and used high content analysis (HCA) to identify genes that regulate the cell cycle...

Claudins provide tight junction barrier selectivity. The human CLDN5 gene contains a high-frequency single-nucleotide polymorphism (rs885985), where the G allele codes for glutamine (Q) and the A allele codes for an amber stop codon. Thus, these different CLDN5 alleles define nested open reading frames (ORFs) encoding claudin-5 proteins that are 303 or 218 amino acids in length. Interestingly, human claudin-16 and claudin-23 also have long ORFs. The long form of claudin-5 contrasts with the majority of claudin-5 proteins in the National Center for Biotechnology Information protein database, which are less than 220 amino acids in length...

The heat shock response (HSR) is a well-conserved, cytoprotective stress response that activates the HSF1 transcription factor. During severe stress, cells inhibit mRNA splicing which also serves a cytoprotective function via inhibition of gene expression. Despite their functional interconnectedness, there have not been any previous reports of crosstalk between these two pathways. In a genetic screen, we identified SF3B1, a core component of the U2 snRNP subunit of the spliceosome, as a regulator of the heat shock response in Caenorhabditis elegans...

Recently, peptide microarrays have been used to distinguish proteins, antibodies, viruses, and bacteria based on their binding to random sequence peptides. We reported on the use of peptide arrays to identify enzyme modulators that involve screening an array of 10,000 defined and addressable peptides on a microarray. Primary peptides were first selected to inhibit the enzyme at low μM concentrations. Then, new peptides were found to only bind strongly with the enzyme-inhibitor complex, but not the native enzyme...

Current measures of core stability utilized by clinicians and researchers suffer from several shortcomings. Three functional movement screens appear, at face-value, to be dependent on the ability to activate and control core musculature. These three screens may present a viable alternative to current measures of core stability. Thirty-nine subjects completed a deep squat, trunk stability push-up, and rotary stability screen. Scores on the three screens were summed to calculate a composite score (COMP). During the screens, muscle activity was collected to determine the length of time that the bilateral erector spinae, rectus abdominus, external oblique, and gluteus medius muscles were active...

Rhizochalinin (Rhiz) is a novel marine natural sphingolipid-like compound which shows promising in vitro and in vivo activity in human castration-resistant prostate cancer (CRPC). In the present study, a global proteome screening approach was applied to investigate molecular targets and biological processes affected by Rhiz in CRPC. Bioinformatical analysis of the data predicted an anti-migratory effect of Rhiz on cancer cells. Validation of proteins involved in the cancer-associated processes, including cell migration and invasion, revealed down-regulation of specific isoforms of stathmin and LASP1, as well as up-regulation of Grp75, keratin 81, and precursor IL-1β by Rhiz...

Vaginal delivery is commonly accepted as a risk factor in pelvic floor dysfunction (PFD), however, other obstetric procedures (episiotomy) are still controversial. In this work, to analyze the relationship between episiotomy and pelvic floor function, a finite element model (FEM) of the pelvic cavity is used considering the pelvic floor muscles (PFM) with damaged regions from spontaneous vaginal delivery, and from deliveries with episiotomy. Common features assessed at screening of PFD are evaluated during numerical simulations of both Valsalva maneuver and contraction...

Over the past few decades, scientists have been trying to identify tissue-specific markers that would help to better understand the pathogenesis of bone and cartilage diseases and could be used clinically for the screening, diagnosis and follow-up of bone or joint diseases. Historically, only a few components known to be involved in bone, mineral or cartilage turnover were available for this purpose (e. g., urine hydroxyproline, serum and urine calcium and phosphate levels). However, since most if not all of these substances have wider biological functions beyond bone, mineral and cartilage metabolism, their clinical value as tissue-specific markers was limited...

Perioperative oral functional management (POFM) involves total oral management of a patient before surgery. Considerable benefits have been reported, but POFM remains scarce in medical settings. An interdisciplinary Medical Hospital Admission Center (MHAC) opened in our hospital in December 2014, and has since provided unified perioperative management for patients. This study reports on the clinical system and contributions of the systematized, standardized POFM applied through the MHAC. Patients awaiting surgery undergo oral screening before admission, with patients classified into three groups: red, needing surgical oral management (tooth extraction or other oral surgery) before surgery; yellow, needing non-surgical oral management before surgery, due to the planned surgery or the risk of tooth injury in connection with general anesthesia; or green, patients with good oral hygiene considered capable of suitable oral self-management...

Antonio Caballero, Juan Luis Ramos
Lignocellulose contains two pentose sugars, l-arabinose and d-xylose, neither of which is naturally fermented by first generation (1G) ethanol-producing Saccharomyces cerevisiae yeast. Since these sugars are inaccessible to 1G yeast, a significant percentage of the total carbon in bioethanol production from plant residues, which are used in second generation (2G) ethanol production, remains unused. Recombinant Saccharomyces cerevisiae strains capable of fermenting d-xylose are available on the market; however, there are few examples of l-arabinose-fermenting yeasts, and commercially, there are no strains capable of fermenting both d-xylose and l-arabinose because of metabolic incompatibilities when both metabolic pathways are expressed in the same cell...
