Project description:Gene expression in primary erythroid cells and in bone marrow stromal cells following treatment with Sotatercept (ACE-011) Gene expression profiles of erythroid cells derived from human CD34+ cells generated under standard conditions and in cultures containing conditioned media from bone marrow stromal cells treated in vitro with ACE-011; Gene expression profiles of untreated bone marrow stromal cells and of stromal cells treated with ACE-011.
Project description:Our goal was to determine whether osteoblastic LuCaP 23.1 prostate cancer xenograft tumors can elicit an osteoblastic response at the gene expression level in human bone marrow stromal cells. Custom Agilent 44K whole human genome expression oligonucleotide microarrays were used to profile bone marrow stroma cells isolated from three patients and treated with either mineralization media or LuCaP 23.1 conditioned medium. Total RNA was isolated and amplified prior to hybridization against a common reference pool of prostate tumor cell lines.
Project description:Purpose: We have used microarrays to identify gene expression profiles that distinguish mouse OS cells from normal pre-osteoblast cells and mature osteoblast cells. Methods: Transcriptional profiles of three cell lines derived from tumors from Osx-Cre p53fl/fl Rbfl/fl (fibroblastic OS) mouse model, and from pre-osteoblast cells (Kusa4b10 mouse bone marrow stromal cell line) and osteoblast cells (derived by in vitro differentiation of the Kusab410 mouse bone marrow stromal cell line) were generated by microarray analysis, each in triplicate, using Affymetrix mouse Gene1.0ST arrays. Transcriptional profiles were analyzed in cell lines derived from tumors from a genetically engineered mouse model of human osteosarcoma (Osx-Cre p53fl/fl Rbfl/fl) and osteoblast cells derived from the Kusa4b10 mouse bone marrow stromal cell line, in the undifferentiated state (pre-osteoblasts) and differentiated state (osteoblasts).

Project description:The interplay between skeletal muscle and bone is primarily mechanical, however, biochemical crosstalk by secreted mediators has recently gained increased attention. The aim of this study was to investigate metabolic effects of conditioned medium from osteoblasts (OB-CM) on myotubes and vice versa. Human skeletal muscle cells incubated with OB-CM showed increased glucose uptake and oxidation, and expression of the glucose transporter (GLUT) 1, while fatty acid uptake and oxidation, and expression of the fatty acid transporter CD36 were decreased. This was supported by proteomic analysis where expression of proteins involved in glucose uptake, glycolytic pathways and TCA cycle were enhanced, and expression of several proteins involved in fatty acid metabolism were reduced. Similar effects on energy metabolism were observed in human bone marrow stromal cells differentiated to osteoblastic cells incubated with conditioned medium from myotubes (SKM-CM), with increased glucose uptake and reduced oleic acid uptake. Proteomic analyses of the two conditioned media revealed many common proteins. Thus, our data may indicate a shift in fuel preference from fatty acid to glucose metabolism in both cell types, induced by conditioned media from the opposite cell type, possibly indicating a more general pattern in communication between these tissues.
