... localization of neuronal (nNOS), endothelial (eNOS), and inducible (iNOS) isoforms of nitric oxide synthase (NOS) in the ovaries of pigs. The intensity of staining is indicated by (-), where staining ... about the expression of nNOS in the ovary. The aim of this study, therefore, was to compare the expression patterns of eNOS, iNOS, and nNOS in the...

In addition to the already described differences in flexibility of the ... relies on the suppression of the expression and activity of inducible nitric oxide synthase (iNOS) by zinc [32,33], released from MT under the in uence...

The rates of uptake of both the lipid and protein components are not matched by the rate of cel- lular metabolism of these species, resulting in the accu- mulation of both ... medium during the chase period allows the turnover of preaccu- mulated protein to be studied in the absence of further cellular uptake. In these studies...

Finally, the Lsm1p Sm domain by itself (LsmDN1DCp) accumu- lates in both the nucleus and the ... its C-terminus also containing a high level of basic lysine residues. However, although deletion of most of the C-terminus abolishes nuclear accumulation of the N-termin...
