Familial adenomatous polyposis coli.
The other mode of treating these patients are subtotal colectomy with ileorectal anastomosis alongwith regular follow up with proctoscopy for development of cancer in retained rectal mucosa(3,7). Recently, Stevan et al. (8) utilized laproscope for total proctocolectomy as well as ileoanal anostomosis while others performed ileopouch anal anastomosis alongwith total proctocolectomy(9,10). Thus t...
متن کاملBinding of the adenomatous polyposis coli protein to microtubules increases microtubule stability and is regulated by GSK3β phosphorylation
Truncation mutations in the adenomatous polyposis coli protein (APC) are responsible for familial polyposis, a form of inherited colon cancer. In addition to its role in mediating beta-catenin degradation in the Wnt signaling pathway, APC plays a role in regulating microtubules. This was suggested by its localization to the end of dynamic microtubules in actively migrating areas of cells and by...
متن کاملAdenomatous polyposis coli protein nucleates actin assembly and synergizes with the formin mDia1
The tumor suppressor protein adenomatous polyposis coli (APC) regulates cell protrusion and cell migration, processes that require the coordinated regulation of actin and microtubule dynamics. APC localizes in vivo to microtubule plus ends and actin-rich cortical protrusions, and has well-documented direct effects on microtubule dynamics. However, its potential effects on actin dynamics have re...
متن کاملAdenomatous Polyposis Coli Associates with the Microtubule-Destabilizing Protein XMCAK
During cell division, the proper formation of a bipolar spindle and its function to segregate chromosomes requires precise coordination of microtubule-stabilizing and destabilizing activities. Globally destabilized, dynamic microtubules radiating from duplicated centrosomes are locally regulated by chromosomes. Proteins at the kinetochore of each sister chromatid mediate a dynamic attachment, a...
متن کاملAdenomatous polyposis coli nucleates actin assembly to drive cell migration and microtubule-induced focal adhesion turnover
Cell motility depends on tight coordination between the microtubule (MT) and actin cytoskeletons, but the mechanisms underlying this MT-actin cross talk have remained poorly understood. Here, we show that the tumor suppressor protein adenomatous polyposis coli (APC), which is a known MT-associated protein, directly nucleates actin assembly to promote directed cell migration. By changing only tw...
