  • Most genes can make more than one message, which determines how the cell acts. (sciencedaily.com)
  • Single-cell analysis is powerful for identifying highly expressed genes that can serve as markers for a cell type can miss many potential drug targets that are expressed at lower levels. (technologynetworks.com)
  • The nuclei from each cell type are then captured by florescence-activated sorting (FACS) to obtain the sequence of the nuclear messages, with the goal of quantifying the expression levels of genes in that cell type. (technologynetworks.com)
  • Below is a non-exhaustive list of in-house infrastructures that are categorized into three overarching themes: bio-imaging, proteins, genes & cells and other resources. (lu.se)
  • Studies in several cancers (including brain, breast, prostate, ovarian, skin) suggest that only a small fraction of the cells within each tumor is capable of giving rise to another tumor. (brainsciencefoundation.org)
  • Cancers are composed of heterogeneous combinations of cells that exhibit distinct phenotypic characteristics and proliferative potentials. (nature.com)
  • Because most cancers have a clonal origin, cancer stem cells (CSCs) must generate phenotypically diverse progenies including mature CSCs that can self-renew indefinitely and differentiated cancer cells that possess limited proliferative potential. (nature.com)
  • Ryk functions as a receptor of Wnt proteins required for cell-fate determination, axon guidance and neurite outgrowth in organisms. (phys.org)
  • A clumping of proteins inside cell bodies in the brain, which may be toxic. (michaeljfox.org)
  • A chemical compound or substance that inhibits oxidation - damage to cells' membranes, proteins or genetic material by free radicals (the same chemical reaction that causes iron to rust). (michaeljfox.org)
