Axons lose their identity
During development, epithelial cells need a little help fi guring out which way is up. < a d d a r t t y p e = " r e l " d o i = " 1 0. 1 0 8 3 / j c b. 2 0 0 8 0 7 1 2 1 " > Jaffe et al.< / a d d a r t > show how a polarizing protein ensures that the cells face the right direction. A newborn epithelial cell in, say, the intestinal lining will polarize so that its apical surface is oriented tow...
متن کاملThe Scorpions Lose Their Sting
23 While it would appear that the decision to incorporate or subsume the Directorate of Special Operations (or Scorpions), into the South African Police Service (SAPS) is a fait accompli, the process of incorporation will not be straightforward. This is largely because the decision to disband the Scorpions is politically motivated, rather than motivated by practical concerns around the function...
متن کاملHow aphids lose their marbles.
Insects provide examples of many cunning stratagems to cope with the challenges of living in a world dominated by surface forces. Despite being the current masters of the land environment, they are at constant risk of being entrapped in liquids, which they prevent by having waxy and hairy surfaces. The problem is particularly acute in an enclosed space, such as a plant gall. Using secreted wax ...
متن کاملRetinal ganglion cells downregulate gene expression and lose their axons within the optic nerve head in a mouse glaucoma model.
Little is known about molecular changes occurring within retinal ganglion cells (RGCs) before their death in glaucoma. Taking advantage of the fact that gamma-synuclein (Sncg) mRNA is expressed specifically and highly in adult mouse RGCs, we show in the DBA/2J mouse model of glaucoma that there is not only a loss of cells expressing this gene, but also a downregulation of gene expression of Snc...
متن کاملTumor-fighting T cells lose their way
Like a tourist without a map, tumor-fighting T cells have a hard time finding their destination without directions. According to Clark et al. (page 2221), dismantling these directions helps skin cancer cells hide from killer T cells. To enter the skin, T cells must grab on to the adhesive molecule E-selectin, which is expressed on the endothelial cells lining blood vessels in the skin. The auth...
