Describe f-scLVM
Single-cell RNA-sequencing (scRNA-seq) allows studying heterogeneity in gene expression in large cell populations. Such heterogeneity can arise due to technical or biological factors, making decomposing sources of variation difficult. F-scLVM (factorial single-cell latent variable model) is a method based on factor analysis that uses pathway annotations to guide the inference of interpretable factors underpinning the heterogeneity. The model jointly estimates the relevance of individual factors, refines gene set annotations, and infers factors without annotation. F-scLVM robustly decomposes scRNA-seq datasets into interpretable components, thereby facilitating the identification of novel subpopulations.

In which chromosome are transgenes inserted in the case of the LiPS-A3S line?
Transgenesis of human pluripotent stem cells (hPSCs) can enable and empower a variety of studies in stem cell research, including lineage tracing and functional genetics studies. While in recent years much progress has been made in the development of tools for gene targeting, little attention has been given to the identification of sites in the human genome where transgenes can be inserted and reliably expressed. One cell line/clone, LiPS-A3, has an integration site in chromosome 15 maintaining robust expression without silencing. Different transgenes can be inserted therein rapidly and efficiently through recombinase-mediated cassette exchange (RMCE). The LiPS-A3 line can greatly facilitate the insertion of reporter and other genes in hPSCs. Targeting transgenes in the LiPS-A3S genomic locus can find broad applications in stem cell research and possibly cell and gene therapy.

How many copies of TP53 does the elephant genome contain?
Here, we show that the elephant genome encodes 20 copies of the tumor suppressor gene TP53 and that the increase in TP53 copy number occurred coincident with the evolution of large body sizes, the evolution of extreme sensitivity to genotoxic stress, and a hyperactive TP53 signaling pathway in the elephant (Proboscidean) lineage. While humans have 1 copy (2 alleles) of TP53, African elephants have at least 20 copies (40 alleles), including 19 retrogenes (38 alleles) with evidence of transcriptional activity measured by reverse transcription polymerase chain reaction.

Are the members of the KRAB-ZNF gene family promoting gene repression?
The stem cell zinc finger 1 (SZF1)/ZNF589 protein belongs to the large family of Kruppel-associated box domain-zinc finger (KRAB-ZNF) transcription factors, which are present only in higher vertebrates and epigenetically repress transcription by recruiting chromatin-modifying complexes to the promoter regions of their respective target genes Because KAP1 is recruited to the DNA via interaction with KRAB-ZNF proteins, we suggest that expression of KRAB-ZNF genes may be controlled via an auto-regulatory mechanism involving KAP1.

Can the radiation of cellphones be dangerous?
two sets of more recent studies with longer exposure duration: the Interphone studies and the Swedish studies led by Dr. Lennart Hardell. The recent studies reach very different conclusions. With four exceptions the industry-funded Interphone studies found no increased risk of brain tumors from cellphone use, while the Swedish studies, independent of industry funding, reported numerous findings of significant increased brain tumor risk from cellphone and cordless phone use.

What is PWMScan?
Transcription factors regulate gene expression by binding to specific short DNA sequences of 5-20 bp to regulate the rate of transcription of genetic information from DNA to messenger RNA. PWMScan is a fast web-based tool to scan server-resident genomes for matches to a user-supplied PWM or transcription factor binding site model from a public database.

Is there a BRCA mutation analysis in the Greek population?
Yes. Molecular analysis of the BRCA1 and BRCA2 genes in 898 Greek families was performed using Sanger sequencing or Next Generation Sequencing for the detection of small insertion/deletion frameshift, nonsynonymous, truncating and splice-site alterations and MLPA for the detection of large genomic rearrangements. In total, a pathogenic mutation was identified in 12.9% of 898 families analyzed. Of the 116 mutations identified in total 9% were novel and 14.7% were large genomic rearrangements.

What is the basis of the DamID experimental protocol?
Dam Identification (DamID) system induced by Cre recombinase using Lamin B1 and mouse embryonic fibroblasts. This inducible system will help to generate genome-wide profiles of chromatin proteins in given cell types and tissues with no need to dissect tissues from organs or separate cells from tissues, which is achieved by using specific regulatory DNA elements and due to the high sensitivity of the method. DNA adenine methyltransferase identification (DamID) has emerged as one of the most comprehensive and versatile methods available for profiling protein-DNA interactions on a genomic scale. Recently, a novel methylation-based tagging technique, termed DamID (DNA adenine methyltransferase identification), has emerged as a powerful tool to decipher transcriptional networks, to study chromatin-associated proteins, and to monitor higher-order chromatin organization on a genome-wide scale. We show here that the in vivo methylation-based tagging technique DamID (DNA adenine methyltransferase identification) can be used for studies of DNA-protein interactions or chromatin profiling in plants DamID is a powerful method used to map the genomic interaction sites of these proteins in vivo It is based on fusing a protein of interest to Escherichia coli DNA adenine methyltransferase (dam). Expression of this fusion protein in vivo leads to preferential methylation of adenines in DNA surrounding the native binding sites of the dam fusion partner. Because adenine methylation does not occur endogenously in most eukaryotes, it provides a unique tag to mark protein interaction sites. DNA adenine methyltransferase identification (DamID) is an enzymatic technology for detecting DNA regions targeted by chromatin-associated proteins. Overall, DamID is highly robust: while the orientation of WT Dam fusions can affect the size of the target sets, their signatures remained largely reproducible.

What is the function of the Spt6 gene in yeast?
Spt6 is a highly conserved histone chaperone that interacts directly with both RNA polymerase II and histones to regulate gene expression. Spt6 is a highly conserved factor required for normal transcription and chromatin structure. Binding of elongation factor Spt6 to Iws1 provides an effective means for coupling eukaryotic mRNA synthesis, chromatin remodelling and mRNA export. Spt6 Is Essential for rRNA Synthesis by RNA Polymerase I. Spt6 (suppressor of Ty6) has many roles in transcription initiation and elongation by RNA polymerase (Pol) II. We identify the histone H3-H4 chaperone Spt6 as the factor that mediates nucleosome reassembly onto the PHO5, PHO8, ADH2, ADY2, and SUC2 promoters during transcriptional repression.

List the members of a network of noncoding regulatory RNAs that play a role in the mammalian brain
In mice, the long ncRNA Cyrano uses an extensively paired site to miR-7 to trigger destruction of this microRNA. Cyrano-directed miR-7 degradation is much more effective than previously described examples of target-directed microRNA degradation, which come primarily from studies of artificial and viral RNAs. By reducing miR-7 levels, Cyrano prevents repression of miR-7-targeted mRNAs and enables accumulation of Cdr1as, a circular RNA known to regulate neuronal activity. Without Cyrano, excess miR-7 causes cytoplasmic destruction of Cdr1as in neurons, in part through enhanced slicing of Cdr1as by a second miRNA, miR-671. Thus, several types of ncRNAs can collaborate to establish a sophisticated regulatory network.
