Biosynthesis of lysosomal hydrolases: Their synthesis in bound polysomes
and the role of co- and post-translational processing in determining their subcellular distribution.
Long-term morphine treatment decreases the association of mu-opioid receptor (MOR1) mRNA with polysomes
The GSE1400 experiment compares two samples, with three replicates each: RNA associated with membrane-bound polysomes
and RNA associated with free polysomes
In addition, GP82 mRNAs were only found associated with polysomes
in metacyclic forms , indicating that transcript mobilization to polysomes
might be involved in regulating GP82 expression, as was reported for another T.
When DON binds to polysomes
and ribosomes within animal cells, it causes peptide chains to be interrupted due to altered initiation and termination sequences.
Under these conditions, monoribosomes (monosomes) migrated to the 15%-30% sucrose layer, while the heavier polyribosomes (polysomes
) migrated to the 60% sucrose cushion.
Translational step inhibited in vivo by aflatoxin B1 in rat-liver polysomes
. Eur J Biochem.
The RER consisted of long lamellae containing a large number of ribosomes adhering to their lamellar walls and near of adjacent free ribosomes, forming polysomes
. Intermediate filaments were observed close to the RER lamellae adjacent to vesicles of variable feature, shape and size (Figs.
Such groups of ribosomes are called polysomes
and apparently allow the message to be used repeatedly before it is degraded.
The crystal structures of these minerals are based on regularly interstratified vaterite-like MC[O.sub.3] (M = Ca, Ba or [Na.sub.2]) and bastnasite-like REE(C[O.sub.3])(F,OH) layer modules (polysomes
) (Donnay and Donnay, 1953; Ni et al., 1993; Yang et al., 1996; Grice and Chao, 1997).
The cytoplasm contains free ribosomes (mostly polysomes
), mitochondria, clear vesicles, and the diplosome (Figs.
