Which is the most well-accepted method for Down syndrome non-invasive prenatal diagnosis?
[ "Currently, two applications for NIPD of Down syndrome have been developed with potential and have displayed positive results; the NIPD using next-generation sequencing technologies and the NIPD using the methylated DNA immunoprecipitation (MeDIP) real-time quantitative polymerase chain reaction (qPCR). This study examined the methylation difference in AIRE and RASSF1A between maternal and placental DNA, and the implication of this difference in the identification of free fetal DNA in maternal plasma and in prenatal diagnosis of trisomy 21. Diagnosis of trisomy 21 was established according to the ratio of fetal-specific AIRE to RASSF1A in maternal plasma. Both methods confirmed that AIRE and RASSF1A were hypomethylated in maternal blood cells but hypermethylated in placental or chorionic villus tissues. It was concluded that hypermethylated AIRE and RASSF1A may serve as fetal-specific markers for the identification of fetal DNA in maternal plasma and may be used for noninvasive prenatal diagnosis of trisomy 21.", "This study examined the methylation difference in AIRE and RASSF1A between maternal and placental DNA, and the implication of this difference in the identification of free fetal DNA in maternal plasma and in prenatal diagnosis of trisomy 21. Similarly, cell-free fetal DNA can be reliably recovered from maternal plasma and assessed by quantitative PCR to detect fetal trisomy 21 and paternally derived single gene mutations. The presence of foetal DNA in the plasma of pregnant women has opened up new possibilities for non-invasive prenatal diagnosis. Moreover, the differential methylation for each locus could be seen during the whole pregnant period." ]

Is the H3K4me3 histone mark related to transcriptional initiation or elongation?
[ "H3K4me3 is associated with transcriptionally active genes, but its function in the transcription process is still unclear. It is well known to occur in the promoter region of genes for transcription activation but its levels correlate positively with the antisense expression levels of the associated sense genes implying that it may be also involved in the activation of antisense transcription. Although it is mostly associated with transcription initiation H3K4me3 levels determine the efficiency of transcription elongation." ]

Elaborate on the association between Genomic Regulatory Blocks (GRBs) and target genes
[ "Genomic regulatory blocks (GRBs) are chromosomal regions spanned by highly conserved non-coding elements (HCNEs), most of which serve as regulatory inputs of one target gene in the region. The target genes are most often transcription factors involved in embryonic development and differentiation. GRBs often contain extensive gene deserts, as well as additional 'bystander' genes intertwined with HCNEs but whose expression and function are unrelated to those of the target gene. GRB target genes have properties that set them apart from their bystanders as well as other genes in the genome: longer CpG islands, a higher number and wider spacing of alternative transcription start sites, and a distinct composition of transcription factor binding sites in their core/proximal promoters. Target gene expression correlates with the acetylation state of HCNEs in the region." ]

[ "Recent functional studies have demonstrated that many microRNAs (miRNAs) are expressed by RNA polymerase II in a specific spatiotemporal manner during the development of organisms and play a key role in cell-lineage decisions and morphogenesis. They are therefore functionally related to a number of key protein coding developmental genes, that form genomic regulatory blocks (GRBs) with arrays of highly conserved non-coding elements (HCNEs) functioning as long-range enhancers that collaboratively regulate the expression of their target genes", "Genomic regulatory blocks (GRBs) are chromosomal regions spanned by highly conserved non-coding elements (HCNEs), most of which serve as regulatory inputs of one target gene in the region.

Which therapeutic interventions for sarcopenia have been applied
[ "The main bulk of experimental pharmacological interventions addressing the clinical problem of frailty have been focused on the use of hormones, as replacement therapy in subjects with low or normal circulating basal levels of the hormone. Results have been disappointing, except for the case of testosterone that have shown some benefits. The effectiveness of other potential therapeutic interventions (antioxidants, anti-inflammatory agents, nutritional supplements) appears to be limited or has not been explored in detail until now." ]

What is the function of cryptochrome-1 in mouse?

[ "Malfunction of the circadian clock has been linked to the pathogenesis of a variety of diseases. We show that mice lacking the core clock components Cryptochrome-1 (Cry1) and Cryptochrome-2 (Cry2) (Cry-null mice) show salt-sensitive hypertension due to abnormally high synthesis of the mineralocorticoid aldosterone by the adrenal gland.", "The Cryptochrome 1 and 2 genes are indispensable for molecular core oscillator function, as evident from the arrhythmic wheel-running behavior and lack of rhythmic clock gene expression in mCry1/mCry2 double-mutant mice in constant darkness.", "Among the components driving the mammalian circadian clock are the Period 1 and 2 (mPer1 and mPer2) and Cryptochrome 1 and 2 (mCry1 and mCry2) genes. A mutation in the mPer2 gene leads to a gradual loss of circadian rhythmicity in mice kept in constant darkness (DD). Here we show that inactivation of the mCry2 gene in mPer2 mutant mice restores circadian rhythmicity and normal clock gene expression patterns. Thus, mCry2 can act as a nonallelic suppressor of mPer2, which points to direct or indirect interactions of PER2 and CRY2 proteins. In marked contrast, inactivation of mCry1 in mPer2 mutant mice does not restore circadian rhythmicity but instead results in complete behavioral arrhythmicity in DD, indicating different effects of mCry1 and mCry2 in the clock mechanism", "Cryptochrome 1 and 2 gene products act in the negative feedback loop and are indispensable for molecular core oscillator function, as evident from the arrhythmic wheel running behaviour and absence of cyclic clock gene expression in mCry1/mCry2 double mutant mice in constant darkness.", ", when mCry-deficient mice are housed in normal light-dark cycles, a single non-circadian peak in neuronal activity can be detected in SCN slices prepared two hours after the beginning of the day. This light-induced increase in electric activity of the SCN suggests that deletion of the mCry genes converts the core oscillator in an hour-glass-like timekeeper and may explain why in normal day-night cycles mCry-deficient mice show apparently normal behaviour.", "Cryptochrome 1 and 2 act as essential components of the central and peripheral circadian clocks for generation of circadian rhythms in mammals", "cryptochrome-1 mRNA was found in DA cells, immunocytochemistry was extended to other components of the circadian clock machinery. This analysis showed that DA cells contain the most common clock-related proteins.", "Cryptochrome 1 and cryptochrome 2 proteins are core components of the mammalian circadian clock and mice mutated in both genes are arrhythmic.", "a domain in the extreme C terminus of BMAL1 that plays an essential role in the rhythmic control of E-box-mediated circadian transcription. Remarkably, the last 43 aa of BMAL1 are required for transcriptional activation, as well as for association with the circadian transcriptional repressor CRYPTOCHROME 1 (CRY1), depending on the coexistence of CLOCK protein.", "circadian rhythm protein cryptochrome 1 (CRY1).", "CRY1 is a master regulator of circadian rhythm that regulates the extracellular calcification of MSCs.", "Studying mouse fibroblasts, we demonstrated that the nutrient-responsive adenosine monophosphate-activated protein kinase (AMPK) phosphorylates and destabilizes the clock component cryptochrome 1 (CRY1). In mouse livers, AMPK activity and nuclear localization were rhythmic and inversely correlated with CRY1 nuclear protein abundance. Stimulation of AMPK destabilized cryptochromes and altered circadian rhythms, and mice in which the AMPK pathway was genetically disrupted showed alterations in peripheral clocks. Thus, phosphorylation by AMPK enables cryptochrome to transduce nutrient signals to circadian clocks in mammalian peripheral organs.", "Cytoplasmic hnRNP D levels displayed a pattern that was reciprocal to the mcry1 oscillation. Knockdown of hnRNP D stabilized mcry1 mRNA and resulted in enhancement of the oscillation amplitude and a slight delay of the phase. Our results suggest that hnRNP D plays a role as a fine regulator contributing to the mcry1 mRNA turnover rate and the modulation of circadian rhythm.", "more than three mutations of conserved PER2 residues impaired not only binding to CRY1 but also subsequent nuclear translocation, although mutations of non-conserved residues did not affect interaction with CRY1. Thus, the conserved amino acid residues of 1179-1198 in PER2 are apparently responsible for binding to CRY1.", "Cryptochrome 1 and 2 (Cry1 and Cry2) are considered essential for generating circadian rhythms in mammals.

Taken together, our data suggest that phase delay in Cry1 transcription is required for mammalian clock function.", "the 24-h mRNA rhythms of the following genes were suppressed in db/db mice compared with control mice: the clock genes period homolog 1/2 (Per1/2) and cryptochrome 1/2 (Cry1/2) and their target genes D site albumin promoter-binding protein (Dbp) and peroxisome proliferator-activated receptor-γ (Pparg) in the aorta and mesenteric arteries; Dbp in the heart; Per1, nuclear receptor subfamily 1, group D, member 1 (Rev-erba), and Dbp in the kidney; and Per1 in the suprachiasmatic nucleus.", "In mammals, circadian rhythms in behavior and physiology are controlled by a central pacemaker, the SCN, and subordinated clocks throughout the body. On the molecular level, these clocks are based on transcriptional/translational feedback loops involving a set of clock genes that regulate their own transcription. Among the components driving the mammalian circadian clock are the Period 1 and 2 (Per1 and Per2) and Cryptochrome 1 and 2 (Cry1 and Cry2) genes. I", "The mammalian clock protein, cryptochrome 1 (CRY1), is degraded via the FBXL3-mediated ubiquitination pathway, suggesting that it is also likely to be targeted by the deubiquitination pathway. Here, we identified that USP2a, a circadian-controlled deubiquitinating enzyme, interacts with CRY1 and enhances its protein stability via deubiquitination upon serum shock. Depletion of Usp2a by shRNA greatly enhances the ubiquitination of CRY1 and dampens the oscillation amplitude of the CRY1 protein during a circadian cycle. By stabilizing the CRY1 protein, USP2a represses the Per2 promoter activity as well as the endogenous Per2 gene expression. We also demonstrated that USP2a-dependent deubiquitination and stabilization of the CRY1 protein occur in the mouse liver.", "The mammalian circadian clock is composed of interlocking feedback loops. Cryptochrome is a central component in the core negative feedback loop, whereas Rev-Erbα, a member of the nuclear receptor family, is an essential component of the interlocking loop.", "By analyzing the Fbxl3 and Cryptochrome 1 double-mutant mice, we found that FBXL3 also regulates the amplitudes of E-box-driven gene expression.

Which are the main functions of the human HuR (ELAVL1) protein in fibroblasts?
[ "HuR is an RNA-binding protein that can stabilize labile mRNAs containing AU-rich elements in their 3' untranslated regions and has been shown to shuttle between the nucleus and cytoplasm. HuR function was previously shown to be implicated in the maintenance of a \"young cell\" phenotype in models of replicative cellular senescence. Loss of HuR is linked to reduced expression of proliferative genes during replicative senescence. Importantly, overexpression of HuR in senescent cells restored a \"younger\" phenotype, while a reduction in HuR expression accentuated the senescent phenotype. HuR associated with the 3' untranslated region of the mRNA encoding the longevity and stress-response protein SIRT1, stabilized the SIRT1 mRNA, and increased SIRT1 expression levels. In mesenchymal cells HuR plays a dominant role in lung development and as a key post-transcriptional regulator of networks guiding tissue remodeling during branching morphogenesis. In fibroblasts knockdown of HuR decreased the endogenous expression of TGFβ1 under exogenous TGFβ1 treatment, simultaneously with the decrease of Col1a, Col3a and fibronectin expression. HuR (human antigen R), represses ARF mRNA translation, thereby maintaining the replicative life span of mouse embryonic fibroblasts (MEFs). HuR is considered a global regulator of cell-cycle progression and tumorigenesis. Through its post-transcriptional influence on specific target mRNAs, HuR can alter the cellular response to proliferative, stress, apoptotic, differentiation, senescence, inflammatory and immune stimuli." ]

Is K-63 linked protein ubiquitination related to proteasomal degradation?
[ "Ubiquitination is best known for its role in targeting proteins for degradation by the proteasome, but evidence of the nonproteolytic functions of ubiquitin is also rapidly accumulating. One example of the regulatory, rather than proteolytic, function of ubiquitin is provided by study of the tumor necrosis factor (TNF) receptor-associated factor (TRAF) proteins, which function as ubiquitin ligases to synthesize lysine 63 (K(63))-linked polyubiquitin chains to mediate protein kinase activation through a proteasome-independent mechanism. Some TRAF proteins, such as TRAF2 and TRAF3, have recently been shown to have a positive role in the canonical pathway that activates nuclear factor kappaB (NF-kappaB) through IkappaB kinase beta (IKKbeta), but a negative role in the noncanonical pathway that activates NF-kappaB through IKKalpha. These opposing roles of TRAF proteins may be linked to their ability to synthesize distinct forms of polyubiquitin chains. Indeed, the TRAF2-interacting protein RIP can mediate IKK activation when it is modified by K(63) polyubiquitin chains, but is targeted to degradation by the proteasome when it is K(48)-polyubiquitinted by the NF-kappaB inhibitor A20.

what is the role of FGF-2 in cardiac regeneration after myocardial infarction?
[ "Exogenous FGF-2 was shown to increase angiogenesis and myocardial perfusion, promote myocardial regeneration by activating the SDF-1α/CXCR4 axis, and thereby improve the cardiac function after myocardial infarction.

What is Tn-seq?
[ "The transposon mutagenesis and high-throughput sequencing (Tn-seq) is a technique that allows for quantitative assessment of individual mutants within a transposon mutant library by sequencing the transposon-genome junctions and then compiling mutant presence by mapping to a base genome. Using Tn-seq, it is possible to quickly define all the insertional mutants in a library and thus identify nonessential genes under the conditions in which the library was produced. Identification of fitness of individual mutants under specific conditions can be performed by exposing the library to selective pressures." ]

Is there any functional association during viral replication between flaviviridae viral RNA depended RNA polymerase and viral helicase?
[ "Several labs have obtained evidence for a protein complex that involves many of the nonstructural (NS) proteins encoded by the virus. NS3, NS4A, NS4B, NS5A, and NS5B appear to interact structurally and functionally. The interaction between the helicase, NS3, and the RNA polymerase, NS5B play a key role in viral replication. Pull-down experiments and surface plasmon resonance data indicate a direct interaction between NS3 and NS5B that is primarily mediated through the protease domain of NS3. This interaction reduces the basal ATPase activity of NS3. However, NS5B stimulates product formation in RNA unwinding experiments under conditions of excess nucleic acid substrate. When the concentrations of NS3 and NS5B are in excess of nucleic acid substrate, NS5B reduces the rate of NS3-catalyzed unwinding. Under pre-steady-state conditions, in which NS3 and substrate concentrations are similar, product formation increased in the presence of NS5B. The increase was consistent with 1:1 complex formed between the two proteins." ]

To investigate the effect of NS3 on classical swine fever virus (CSFV) NS5B RNA-dependent RNA polymerase activity (RdRp) activity and NS3-NS5B interaction, RdRp reactions, GST-pull-down assays and co-immunoprecipitation analyses containing NS5B and either of NS3 protein and the different truncated NS3 mutants were performed, respectively. We found that NS3 stimulated NS5B RdRp activity in a dose-dependent manner by binding to NS5 through a NS3 protease domain. Furthermore, mapping important regions of the NS3 protease domain was carried out by deletion mutagenesis, associated with RdRp reactions, GST-pull-down assays and co-immunoprecipitation analyses. Results showed that stimulation of CSFV NS5B RdRp activity was obtained by NS3 binding to NS5B through a 31-amino acid fragment at the N-terminal end of NS3 protease domain, which mediated a specific NS3-NS5B interaction.", "The protocols detailed in this unit are used to purify three recombinant enzymes that are widely used in HCV research: the HCV NS3 protease domain, the helicase domain as an NS3+NS4A complex, and the NS5B RNA-dependent RNA polymerase.

Are defects in recombination repair involved in carcinogenesis?
[ "Yes. The breast cancer-associated BRCA1 and BRCA2 proteins are strongly implicated in recombination repair.", "Carcinogenesis or oncogenesis or tumorigenesis is literally the creation of cancer. It is a process by which normal cells are transformed into cancer cells. It is characterized by a progression of changes at the cellular, genetic and epigenetic level that ultimately reprogram a cell to undergo uncontrolled cell division, thus forming a malignant mass.\nCarcinogenesis is caused by mutation and epimutation of the genetic material of normal cells, which upsets the normal balance between proliferation and cell death. This results in uncontrolled cell division and the evolution of those cells by natural selection in the body. The uncontrolled and often rapid proliferation of cells can lead to benign tumors; some types of these may turn into malignant tumors (cancer). Based on studies, carcinogenesis also related with the defects in recombination repair." ]

", "Although alcohol consumption is related to increased cancer risk, its molecular mechanism remains unclear. Here, we demonstrate that an intake of 10% alcohol for 4 weeks in rats is genotoxic due to induction of micronuclei. Acetaldehyde (AA), the first product of ethanol metabolism, is believed to be responsible for DNA damage induced by alcohol.

For colorectal cancer, the loss of mismatch repair gene activity is a key genetic determinant. Nucleotide excision repair (NER), recombination repair (RR) and base excision repair (BER) pathways have critical roles in protection against other cancers, and we wished to investigate their role in colorectal cancer.

What is the biological role of SERCA2 SUMOylation in cardiac physiology and pathophysiology, such as in heart failure?
[ "Recently, the impact of small ubiquitin-related modifier 1 (SUMO-1) on the regulation and preservation of sarcoplasmic reticulum calcium adenosine triphosphatase (SERCA2a) function was discovered. The small ubiquitin-related modifier (SUMO) can be conjugated to lysine residues of target proteins, and is involved in many cellular processes. SERCA2a is SUMOylated at lysines 480 and 585 and this SUMOylation is essential for preserving SERCA2a ATPase activity and stability in mouse and human cells. The levels of SUMO1 and the SUMOylation of SERCA2a itself were greatly reduced in failing hearts. SUMO-1 gene transfer improved cardiac function supporting the critical role of SUMO-1 in SERCA2a function and underlining the therapeutic potential of SUMO-1 for HF patients." ]

How functional connectivity of the default mode network changes in patients with disorders of consciousness?
[ "Functional connectivity in the default mode network (DMN) is reduced in patients with different disorders of consciousness, and correlates with the level of consciousness. \nSpecifically, functional connectivity in the default mode network was shown to be absent in brain death patients, extremely low in vegetative state patients and slightly decreased in minimally conscious state patients when compared to healthy subjects. Therefore, functional connectivity in the default mode network was suggested to be valuable in differentiating patients with different disorders of consciousness.

What is the function of the AtxA pleiotropic regulator?
[ "AtxA is the gene encoding the trans-activator of anthrax toxin synthesis and is essential for virulence of B. anthracis. It is located on the resident 185-kb plasmid pXO1 and its activation is stimulated by bicarbonate. AtxA controls the expression of more than a hundred genes belonging to all genetic elements, the chromosome and both virulence plasmids, including those encoding the major virulence factors. AtxA can activate or repress gene expression. In atxA+ strains, toxin gene expression is increased 5- to 20-fold in cells grown in 5% CO2 relative to cells grown in air. Dual promoters control expression of AtxA. Transcription of the atxA gene occurs from two independent promoters, P1 and P2, whose transcription start sites are separated by 650 bp.", "Comparison of the resulting protein patterns indicated that synthesis of non-toxin proteins is influenced by growth in elevated CO2 and the toxin gene regulator, atxA. The AtxA virulence regulator of Bacillus anthracis is required for toxin and capsule gene expression. DNA sequence analysis of transposon insertion sites in 17 mutants carrying CO2- and atxA-regulated fusions revealed 10 mutants carrying independent insertions on the 185-kb toxin plasmid pXO1 which did not map to the toxin genes. We purified histidine-tagged AtxA [AtxA(His)] from Escherichia coli and used anti-AtxA(His) serum to detect AtxA in protein preparations from B. anthracis cells.", "The atxA gene product activates transcription of the anthrax toxin genes and is essential for virulence." ]

Is NOD1 activated in inflammation?
[ "Nod proteins fight off bacterial infections by stimulating proinflammatory signaling and cytokine networks and by inducing antimicrobial effectors, such as nitric oxide and antimicrobial peptides. NOD1 engagement generates an inflammatory response via activation of NFκB and MAPK pathways and several inflammatory disorders, such as Crohn's disease and asthma, are linked to genetic changes in either Nod1 or Nod2. Nod1 is also critically implicated in shaping adaptive immune responses towards bacterial-derived constituents. Together, Nod1 and Nod2 represent central players in the control of immune responses to bacterial infections and inflammation. Mice deficient for both Nod1 and Nod2 had attenuated inflammatory pathology, reduced levels of inflammatory cytokines, and increased colonization of the mucosal tissue", "Nod1/2 DKO mice show increased susceptibility for intestinal permeability while vascular permeability was not affected. The present study analyzed Nod1 and Nod2 double deficient (Nod1/2 DKO) mice under physiological and inflammatory conditions. The increased intestinal permeability is associated with enhanced inflammatory cytokine production and epithelial cell proliferation in Nod1-deficient mice as compared with wild-type mice.
