(Submitter supplied) We have identified GATA-3 as a critical regulator of luminal cell differentiation in the mammary gland. Acute loss of GATA-3 in the adult mammary gland leads to an expansion of an undifferentiated luminal epithelium and the formation of a multi-layered epithelium. Here we report microarray analysis of mammary glands that have undergone acute loss of GATA-3 Keywords: genetic modification

(Submitter supplied) The developing mammary gland contains distinct microenvironments that perform specialized functions for branching and ductal invasion. These microenvironments include the terminal end buds (TEBs) at the tips of invading primary ducts and the more differentiated proximal ducts that give rise to side branches. We have devised a novel microarray approach to identify genes that are expressed in the epithelium and stroma of these distinct microenvironments. more...

(Submitter supplied) The CCND1 gene, which is frequently overexpressed in cancers, encodes the regulatory subunit of a holoenzyme that phosphorylates the retinoblastoma protein (pRb). It is known that cyclin D1 regulates ERα transactivation using heterologous reporter systems, the significance of this observation to E2 dependent gene activation is unknow. E2 stimulated MCF7 cells treated with cyclin D1 siRNA in order to analyze the genes regulated by estradiol in a cyclin D1 dependent manner. more...

(Submitter supplied) Ovariectomized virgin Ccnd1-/- and Ccnd1+/+ mice (5 weeks of age) were allowed to recuperate for 2 weeks. The mice were assigned to either replacement pellets containing E2 (0.75 mg, 60-day release) or pellet containing placebo. Mice were sacrificed at day 7 after pellet implantation. RNA extracted from mammary glands (3 each group) was labeled and used to probe Affymetrix 430_2.0 arrays.

(Submitter supplied) The jmjC-domain containing H3K4 histone demethylase JARID1B/KDM5B/PLU1 is over-expressed in human breast cancer and is a potential target for breast cancer treatment. To investigate the in vivo function of JARID1B, we developed a new strain of Jarid1b knockout mice and characterized the phenotypes in detail. Unlike previously reported knockout strains, the majority of our Jarid1b knockout mice are viable beyond embryonic and neonatal stages. more...

(Submitter supplied) Mucoepidermoid carcinomas (MEC) is the most common salivary gland malignancy. To date, advanced and nonresectable MEC have poor prognosis and no effective treatment. The CRTC1-MAML2 fusion oncogene, which is associated with more than 50% of MEC, consists of the N-terminal CREB-binding domain of the CREB transcriptional co-activator CRTC1 and the C-terminal transcriptional activation domain of the Notch transcriptional co-activator MAML2. more...

(Submitter supplied) The role of diet in the prevention of breast cancer is widely accepted, yet little is known on how early dietary effects mitigate adult cancer risk. Soy consumption is associated with reduced breast cancer risk in women, an effect largely attributed to the soy isoflavone genistein (GEN). We previously showed lower chemically-induced mammary tumor incidence in young adult rats with lifetime dietary intake of soy protein isolate (SPI), a highly refined soy product in infant formula, than in those fed the control diet Casein (CAS). more...

(Submitter supplied) The terminal end buds (TEB) are the growing part of the ductal mammary epithelium during puberty, which enable the formation of the primary mammary epithelial network. These bulbous end structures are highly proliferative, and this allows the ductal expansion into the mammary fat pad. The TEB comprise of an outer cap cell layer, which include the progenitor cells of the myoepithelium, and the body cells, which are thought to be the progenitors from which the luminal epithelium is formed. more...

(Submitter supplied) Transcriptional profiling of mouse embryonic kidneys (E13.5) comparing UB HDAC1,2-/- kidneys with wild type kidneys. Studies in our lab showed that histone deacetylase 1 (HDAC1) and 2 (HDAC2) perform redundant, yet essential functions in the developing mouse ureteric bud (UB) tissue. Double deletion of HDAC1 and HDAC2 in the UB results in impaired UB branching morphogenesis, followed by severe kidney dysgenesis. more...
