CaMKII is a key mediator of Wnt/Ca2+ signaling although a further subset of the non-canonical Wnt signaling via Wnt5A is proposed to be a β-catenin degradation pathway which does not require activation of CaMKII [33].
A further subset of this group (55.6%, n = 281/505) identified themselves as married or cohabiting.
Here, we analyse the specificity of a further subset of antibodies to APC.

To further enhance the utility of these resources for linkage analysis, we used a further pruned subset of the linkage panel to generate multipoint identity by descent matrices.
A further random subset of these images was re-read for intraclass correlation coefficients (ICCs) with 0.93 and 0.94 for subgastrocnemius bursitis and popliteal cysts, respectively.

DOI: 10.1038/sj/bjc/6600131 www.bjcancer.com © 2002 Cancer Research UK Although vulval squamous cell carcinoma (SCC) is less common than cervical cancer, it is nevertheless of interest since a proportion of cases contain sequences from high-risk human papillomavirus (HPV) types (principally HPV 16), whereas a further, substantial subset of cancers arise via HPV-independent pathways.
In a further experimental subset, 33 piglets were allocated to the 4 experimental groups as described above to determine plasma NEFA concentrations at day 21 of FR (C and R pigs), day 7 (R pigs only) and day 21 of RFD (C and R pigs).
