  • Overexpression of PLD3 leads to a significant decrease in intracellular amyloid-β precursor protein (APP) and extracellular Aβ42 and Aβ40 (the 42- and 40-residue isoforms of the amyloid-β peptide), and knockdown of PLD3 leads to a significant increase in extracellular Aβ42 and Aβ40. (nih.gov)
  • In contrast, antibodies to the envelope (ENV) precursor protein gp160 and the final ENV proteins (gp120 and gp41) can be detected in specimens from virtually all HIV-infected persons regardless of clinical stage (4-9). (cdc.gov)
  • These are the genes activated by heat shock and other forms of stress and they churn out a lot of HSP70 chaperone in order to save the cells. (blogspot.com)
  • This is an example of the kind of gene that will be missed in the screen because the cells were not stressed during the screening. (blogspot.com)
  • All your cells have the same genes but look and act differently. (cdc.gov)
  • Cadherins are calcium dependent proteins which hold cells together at adherins junctions to form tissues and organs. (cdc.gov)
  • The viral S gene is important as it codes for the Spike protein which is the molecule that makes contact with, and allows entry of the virus into susceptible host cells, causing infection. (who.int)
  • An amino acid is the fundamental molecule that serves as the building block for proteins. (genome.gov)
  • Even though half of a person's genes come from each parent, some traits are more likely to be inherited from the mother or father . (familyeducation.com)
  • The baby's parents, in turn, inherited half of their genes from each of their own parents so one-quarter of each person's genes, therefore, come from their grandparents. (familyeducation.com)
  • gene loci structures and their regulation. (nature.com)
  • ABSTRACT Factor VII gene polymorphisms may contribute to elevations in factor VII coagulant (FVIIc) levels that have been associated with cardiovascular risk. (who.int)
  • The impor- objectives of determining the frequencies tance of FVII in normal haemostasis is il- of these gene polymorphisms in the popula- lustrated by the severe bleeding diathesis tion and clarifying the genotype association associated with low plasma levels of the of the R353Q and 0/10 bp insertion poly- protein [ 3 ].

  • But sometimes non-coding segments are left in, or seemingly important regions are spliced out. (newscientist.com)
  • By varying what RNA regions are stitched together, the same gene can provide multiple templates for slightly altered proteins. (newscientist.com)
  • These coding regions are called genes. (familyeducation.com)
  • One of the annoying things about all three papers is that they use the words "gene" and "protein-coding gene" as synonyms. (blogspot.com)
  • Intriguingly, some of the top-ranked transcripts are noncoding splicing isoforms, which imply diverse gene regulation mechanisms. (nature.com)
  • Up-regulation of adipogenin, an adipocyte plasma transmembrane protein, during adipogenesis. (nih.gov)
  • Studies in mouse indicate the 80 aa SMAF1 protein is involved in adipocyte tissue function or regulation. (nih.gov)
  • Transcriptional regulation of the genes in metabolic pathways is a highly successful strategy, which is virtually universal in microorganisms. (lu.se)
  • Here, the function of regulation is quite clear: expressing energy and carbon, that a number around 0.2% would be the right genes at the right time will enable the cell to make the expected, and that the difference is more or less specific to the lac most of the resources within its reach, by maximizing the uptake operon [7]. (lu.se)
  • A number of studies have explored how regulation of generally, and at least to a first approximation, it is obvious that metabolic pathways affects the growth rate of microorganisms, gene regulation only is useful if the environmental conditions vary both in the steady state and in response to changes in the local with time. (lu.se)
  • These gene annotations correspond to D. melanogaster release 6.52 . (wustl.edu)
  • Giardia lamblia encodes several families of cysteine-rich proteins, including the Variant-specific Surface Proteins (VSPs) involved in the process of antigenic variation. (ucc.edu.ar)
