| Abstract |
We investigate the immunoreactivity of serine/threonine kinase 33 (Stk33) and of vimentin in the brain of mouse, rat and hamster. Using a Stk33-specific polyclonal antibody, we show by immunofluorescence staining that Stk33 is present in a variety of brain regions. We found a strong staining in the ependymal lining of all cerebral ventricles and the central canal of the spinal cord as well as in hypothalamic tanycytes. Stk33 immunoreactivity was also found in circumventricular organs such as the area postrema, subfornical organ and pituitary and pineal glands. Double-immunostaining experiments with antibodies against Stk33 and vimentin showed a striking colocalization of Stk33 and vimentin. As shown previously, Stk33 phosphorylates recombinant vimentin in vitro. Co-immunoprecipitation experiments and co-sedimentation assays indicate that Stk33 and vimentin are associated in vivo and that this association does not depend on further interacting partners (Brauksiepe et al. in BMC Biochem 9:25, 2008). This indicates that Stk33 is involved in the dynamics of vimentin polymerization/depolymerization. Since in tanycytes the vimentin expression is regulated by the photoperiod (Kameda et al. in Cell Tissue Res 314:251-262, 2003), we determine whether this also holds true for Stk33. We study hypothalamic sections from adult Djungarian hamsters (Phodopus sungorus) held under either long photoperiods (L:D 16:8 h) or short photoperiods (L:D 8:16 h) for 2 months. In addition, we examine whether age-dependent changes in Stk33 protein content exist. Our results show that Stk33 in tanycytes is regulated by the photoperiod as is the case for vimentin. Stk33 may participate in photoperiodic regulation of the endocrine system. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 September 2014.
All research outputs
#21,178,329
of 23,839,820 outputs
Outputs from Cell and Tissue Research
#2,002
of 2,279 outputs
Outputs of similar age
#179,364
of 204,711 outputs
Outputs of similar age from Cell and Tissue Research
#11
of 15 outputs
Altmetric has tracked 23,839,820 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,279 research outputs from this source. They receive a mean Attention Score of 3.3. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 204,711 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 15 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
