Math5, a mouse homolog of the Drosophila proneural bHLH transcription factor Atonal, is essential in the developing retina to establish retinal progenitor cell competence for a ganglion cell fate. Elucidating the mechanisms by which Math5 influences progenitor cell competence is crucial for understanding how specification of neuronal cell fate occurs in the(More)
INTRODUCTION Genomic and transcriptomic alterations affecting key cellular processes such us cell proliferation, differentiation and genomic stability are considered crucial for the development and progression of cancer. Most invasive breast carcinomas are known to derive from precursor in situ lesions. It is proposed that major global expression(More)
Brn3b/Brn-3.2/POU4f2 is a POU domain transcription factor that is essential for retinal ganglion cell (RGC) differentiation, axonal outgrowth and survival. Our goal was to establish a link between Brn3b and the downstream events leading to RGC differentiation. We sought to determine both the number and types of genes that depend on Brn3b for their(More)
During vertebrate retinal development, the seven retinal cell types differentiate sequentially from a single population of retinal progenitor cells (RPCs) and organize themselves into a distinct laminar structure. The purpose of this study was to determine whether beta-catenin, which functions both as a nuclear effector for the canonical Wnt signaling(More)
The vertebrate retina develops from an amorphous sheet of dividing retinal progenitor cells (RPCs) through a sequential process that culminates in an exquisitely patterned neural tissue. A current model for retinal development posits that sequential cell-type differentiation is the result of changes in the intrinsic competence state of multipotent RPCs as(More)
Background: Estrogens are known to regulate the proliferation of breast cancer cells and to modify their phenotypic properties. Identification of estrogen-regulated genes in human breast tumors is an essential step toward understanding the molecular mechanisms of estrogen action in cancer. To this end we generated and compared the Serial Analysis of Gene(More)
Genetically engineered mouse mammary cancer models have been used over the years as systems to study human breast cancer. However, much controversy exists on the utility of such models as valid equivalents to the human cancer condition. To perform an interspecies gene expression comparative study in breast cancer we used a mouse model that most closely(More)
BACKGROUND Reliable stability and yield of RNA from breast cancer tissues are important for biobanking, clinical trials, and diagnostic testing. METHODS Aliquots of fresh primary tumor tissue from 17 surgically resected invasive breast cancers were placed into RNAlater at room temperature after tumor removal (baseline) and up to 3 hours thereafter or were(More)
A correction to Transcriptomic changes in human breast cancer progression as determined by serial analysis of gene expression In this research article [1], the order of figures 3 and 4 has been reversed although the order of the figure titles and legends is correct. CM: Transcriptomic changes in human breast cancer progression as determined by serial(More)
