Beta-catenin Controls Metastasis in Braf-activated Pten-inactivated Melanomas

Project description:Malignant melanoma is characterized by frequent metastasis, however specific changes that regulate this process have not been clearly delineated. Although it is well known that Wnt signaling is frequently dysregulated in melanoma, the functional implications of this observation are unclear. By modulating beta-catenin levels in a mouse model of melanoma that is based on melanocyte-specific Pten loss and BrafV600E mutation, we demonstrate that beta-catenin is a central mediator of melanoma metastasis to lymph node and lung. In addition to altering metastasis, beta-catenin levels control tumor differentiation and regulate both MAPK/Erk and PI3K/Akt signaling. Highly metastatic tumors with beta-catenin stabilization are very similar to a subset of human melanomas; together these findings establish Wnt signaling as a metastasis regulator in melanoma. MoGene-1_0-st-v1: Four samples total. Two biological replicates of uncultured Pten/Braf murine melanomas and two biological replicates of uncultured Pten/Braf/Bcat-STA murine melanomas. MoEx-1_0-st-v1: Two samples total. Dissociated tumor and FACS-enriched Pten/Braf and Pten/Braf/Bcat-STA murine melanoma.

The rexinoid, bexarotene, prevents the development of premalignant lesions in MMTV-erbB2 mice.

Project description:Retinoids, vitamin A analogues that bind to retinoic acid receptor (RAR) or retinoid X receptor (RXR), play important roles in regulating cell proliferation, apoptosis, and differentiation. Recently, RXR-selective ligands, also referred to as rexinoids, have been investigated as potential chemopreventive agents for breast cancer. Our previous studies demonstrated that the rexinoid bexarotene significantly prevented ER-negative mammary tumourigenesis with less toxicity than naturally occurring retinoids in animal models. To determine whether bexarotene prevents cancer at the early stages during the multistage process of mammary carcinogenesis, we treated MMTV-erbB2 mice with bexarotene for 2 or 4 months. The development of preinvasive mammary lesions such as hyperplasias and carcinoma-in-situ was significantly inhibited. This inhibition was associated with reduced proliferation, but no induction of apoptosis. We also examined the regulation of a number of rexinoid-modulated genes including critical growth and cell cycle regulating genes using breast cell lines and mammary gland samples from mice treated with rexinoids. We showed that two of these genes (DHRS3 and DEC2) were modulated by bexarotene both in vitro and in vivo. Identification of these rexinoid-modulated genes will help us understand the mechanism by which rexinoid prevents cancer. Such rexinoid-regulated genes also represent potential biomarkers to assess the response of rexinoid treatment in clinical trials.

Expression data of three sets of cells: (1) Schwann cells and macrophages from 1m-old WT DRG, (2) Schwann cells (Nf1-/-) and macrophages (Nf1+/+) from 1m-old neurofibroma, (3) Schwann cells (Nf1-/-) and macrophages (Nf1+/+) from 7m-old neurofibroma

Project description:Schwann cells and macrophages were dissociated from normal DRGs and 1- and 7-month-old neurofibroma. Schwann cells from neurofibroma have Nf1-/- phenotypes. All macrophages have Nf1+/+ phenotypes. We used microarrays (Affymetrix MoGene 2.0 ST GeneChip) to detect transcriptomal changes between 7-month-old neurofibroma Schwann cells (or macrophages) versus 1-month-old wild-type (or neurofibroma) Schwann cells (or macrophages). Expression data of three sets of cells: (1)Schwann cells and macrophages from 1-month-old wild-type mouse dorsal root ganglia, (2) Schwann cells (Nf1-/-) and macrophages (Nf1+/+) from 1-month-old neurofibroma, (3) Schwann cells (Nf1-/-) and macrophages (Nf1+/+) from 7-month-old neurofibroma We chopped mouse DRG/neurofibromas into 1-3 mm^3 pieces and plated them in dissociation medium containing 20mL L-15 (Mediatech), 0.5 mg/mL collagenase type 1 (Worthington; Lakewood, NJ), and 2.5 mg/mL dispase protease type II (Cambrex; East Rutherford, NJ) at 37Â°C for 4-6 hours with shaking. The dissociation reaction was stopped by adding DMEM +10%FBS. Undigested DRG/tumors were excluded by 100ÂµM cell strainer. Cells were collected by centrifugation. For each microarrays (Schwann cell, macrophage), Affymetrix GeneChip Command Console (v4.0.0) was used to create .chp files. All the probe sets on Affymetrix Mouse Gene 2.0 ST array (Mogene-2_0-st-v1.na33.2.mm10) were summarized by Affymetix Expression Console program using robust multi-chip average (RMA) method . After preprocessing steps, data from two batches were combined and their batch effects were corrected using ComBat method Please note that [1] all MP samples are Nf1+/+ (no mutation on Nf1 gene) and the only difference is their ages (1month, 7month) and [2] the 'nf1' in sample title reperesents "neurofibroma type1 disease", not "Nf1 gene".
