| Method |
FRAP (fluorescence recovery after photobleaching). Primary source [99] abstract: "The effects of mitosis on gap junctional intercellular communication (GJIC) were quantified in a clonal cell line of spontaneously immortalized rat granulosa cells (SIGC) using a fluorescence recovery after photobleaching assay." Primary source [100] abstract: "Western blotting studies revealed that connexin43 (Cx43), one of the major gap junction proteins in human vascular endothelial cells, is posttranslationally modified during mitosis." |
| Comments |
P.210 left column bottom paragraph: "Gap junctional communication is regulated during the progression of
the cell cycle. Gap junctional communication, measuring dye spread via fluorescence recovery after photobleaching, was dramatically reduced in mitotic cells and gradually recovered between 1–4 h after telophase
(primary sources)." Primary source [99] studied rat ovarian granulosa cell line and limited studies were conducted with
an SV40-transformed monkey kidney cell line (COS-1, ATCC, Rockville,
MD), a cell line derived from bovine coronary venular endothelial
cells (CVRC) [ref 11 therein], an SV40-transformed rat granulosa cell line
(SVGC), tumor-derived, SV40-transformed SIGC cells (T-SV-SICC)[ref 10 therein], and rat uterine myometrial cells. Primary source [100] studied Human umbilical vein endothelial cells (HUVEC), and Rat vascular smooth muscle cells. |
