A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Marquage par immunofluorescence d'astrocytes tumoraux ou astrocytomes (lignée cellulaire humaine U373), montrant en rouge, APC et en vert, la tubuline des microtubules. APC est un supresseur de tumeur qui est impliqué dans la polarisation des astrocytes normaux. La localisation d'APC est altérée dans des lignées de gliomes. Pour essayer de corriger, les dérèglements observés lors de la migration des cellules d'astrocytes tumuraux ou gliomes on cherche à connaitre les mécanismes moléculaires fondamentaux qui controlent la polarisation et la migration cellulaire.

Adenomatous Polyposis Coli (APC) is a tumor suppressor protein involved in the initiation and progression of colon cancer. The most widely accepted function ofAPC is to participate to the Wnt signaling pathway, by downregulating beta-catenin and thereby controlling gene transcription and cell proliferation. However, APC is clearly a multifunctional protein whose loss contributes to tumor formation in multiple ways. Regulation of APC localization during cell migration and the ability of APC to bind multiple polarity proteins and microtubule-associated molecules support the idea that APC plays a key role in directed cell migration and that this function may contribute to its tumour suppressor activity.
