Abstract

Using a mouse mammary tumor model based on orthotopic transplantation of luciferase-expressing mouse ILC cells (KEP1-Luc cells), we evaluated the diagnostic value of three clinically applied tracers: (99m)Tc-(V)-DMSA, (99m)Tc-MIBI, and (99m)Tc-HDP. Uptake of the tracers is compared using static and dynamic imaging procedures. We found that dynamic imaging in combination with pixel-by-pixel color coding has an added value over (high resolution) static imaging procedures. Such dynamic imaging procedures could enhance the potential of breast-specific gamma-imaging.

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins.
