Colon carcinoma is one of the leading causes death from cancer and characterized by a heterogenic pool cells with distinct differentiation patterns. Recently, it was reported that population undifferentiated primary tumor, so-called stem (CSC), can reconstitute original tumor on xenotransplantation. Here, we show spheroid cultures these colon CSCs contain expression CD133, CD166, CD44, CD29, CD24, Lgr5, nuclear beta-catenin, which have all been suggested to mark (cancer) cell population....
Betulinic Acid (BetA) and its derivatives have been extensively studied in the past for their anti-tumor effects, but relatively little is known about precursor Betulin (BE). We found that BE induces apoptosis utilizing a similar mechanism as BetA prevented by cyclosporin A (CsA). cell death more rapidly compared to BetA, achieve amounts of considerably higher concentration needed. Interestingly, we observed cholesterol sensitized cells BE-induced apoptosis, while there was no effect when...
Induction of apoptosis by the cell surface receptor CD95 (APO-1/Fas) has been shown to involve activation a family cysteine proteases (caspases). Recently, new member this identified, designated FLICE (caspase-8/MACH/Mch5). is part death-inducing signaling complex and therefore most upstream caspase in apoptotic pathway. A total eight different isoforms (caspase-8/a–h) have described. To determine which are expressed cells we generated panel monoclonal antibodies directed against all...
Colon cancer stem cells (CSC) can be identified with AC133, an antibody that detects epitope on CD133. However, recent evidence suggests expression of CD133 is not restricted to CSCs, but also expressed differentiated tumor cells. Intriguingly, we observed detection the AC133 cell surface decreased upon differentiation CSC in a manner correlated loss clonogenicity. this event did coincide change promoter activity, mRNA, splice variant, protein expression, or even In contrast, noted...
The metastatic process of colorectal cancer (CRC) is not fully understood and effective therapies are lacking. We show that activation NOTCH1 signaling in the murine intestinal epithelium leads to highly penetrant metastasis (100% metastasis; with >80% liver metastases) Kras
Abstract In colorectal cancer (CRC), a subpopulation of tumor cells, called stem cell (CSC) fraction, is suggested to be responsible for initiation, growth, and metastasis. The search reliable marker identify these CSCs ongoing as current markers, like CD44 CD133, are more broadly expressed therefore not highly selective currently also lack function in CSC biology. Here, we analyzed whether the Wnt target Lgr5, which has earlier been identified murine intestinal could potentially serve...
