Bone morphogenetic protein 4 induces differentiation of colorectal cancer stem cells and increases their response to chemotherapy in mice.

2010

BACKGROUND & AIMS: The limited clinical response observed in many patients with colorectal cancer may be related to the presence of chemoresistant colorectal can- cer stem cells (CRC-SCs). Bone morphogenetic protein 4 (BMP4) promotes the differentiation of normal colonic stem cells. We investigated whether BMP4 might be used to induce differentiation of CRC-SCs and for therapeutic purposes. METHODS: CRC-SCs were isolated from 25 tumor samples based on expression of CD133 or using a selection culture medium. BMP4 expression and activity on CRC-SCs were evaluated in vitro; progeny of the stem cells were evaluated by immunofluorescence, immuno- blot, and flow cytometry analyses. The potential …

Luun morfogeneettisen proteiini 4:n kohdegeenien SKIL ja ID2 vaikutukset rintasyöpäsoluihin

2017

Rintasyöpä on johtava naisten syöpäkuolemien aiheuttaja maailmanlaajuisesti. Luun morfogeneettiset proteiinit (BMP) ovat tranformoiva kasvutekijä beta- superperheeseen kuuluvia proteiineja. BMP:den tiedetään olevan osallisina monissa syöpätyypeissä. Rintasyövässä BMP4:llä on merkittäviä vaikutuksia solukasvuun, liikkuvuuteen ja levinnäisyyteen. Aiempien tutkimusten mukaan BMP4:n on havaittu laskevan solukasvua merkittävästi rintasyöpäsoluilla. Tämän tutkimuksen kohteena oli kaksi BMP4:n kohdegeeniä, ID2 (Inhibitor of DNA binding 2) ja SKIL eli SKI-like proto-onkogeeni. Hypoteesina oli selvittää johtuuko BMP4:n vaikutukset solukasvuun ID2- tai SKIL-geenistä. BT-474 ja T-47D rintasyöpäsoluja …

Colorectal Cancer Stem Cells and Cell Death

2011

Nowadays it is reported that, similarly to other solid tumors, colorectal cancer is sustained by a rare subset of cancer stem-like cells (CSCs), which survive conventional anticancer treatments, hanks to efficient mechanisms allowing escape from apoptosis, triggering tumor recurrence. To improve patient outcomes, conventional anticancer therapies have to be replaced with specific approaches targeting CSCs. In this review we provide strong support that BMP4 is an innovative therapeutic approach to prevent colon cancer growth increasing differentiation markers expression and apoptosis. Recent data suggest that in colorectal CSCs, protection from apoptosis is achieved by interleukin-4 (IL-4) a…
