Identification of hormone-correlated genes as biomarkers for menstrual cycle phases and menopausal status

ABSTRACT: Gene and protein expression in the breast varies relative to menopausal status (MS) and menstrual phase (MP), but cancer risk biomarker research using archived benign breast samples is usually uninformed by MS-MP data. We hypothesized that gene expression variation relative to ambient hormones can be exploited to develop markers of MS-MP that can be measured directly in breast tissue. Random fine needle aspiration samples from the unaffected breasts of 18 women were utilized for Illumina microarray analysis. Gene expression was correlated with simultaneous serum levels of estradiol, progesterone, and follicle stimulating hormone (FSH). True MS-MP states were defined by age and serum hormones. Genes highly correlated to serum hormones were used to classify samples into 2 MS groups: premenopause or postmenopause. The premenopausal samples were further classified into 3 MP groups: early follicular, late follicular or luteal.

Project description:Even though cutaneous atrophy is the major adverse effect of topical glucocorticoids, its molecular mechanisms are poorly understood. We found that glucocorticoids strongly increased the expression of REDD1 (regulated in development and DNA damage response 1), a stress-inducible inhibitor of mTOR, in mouse and human epidermis. We found that REDD1 knockout animals are partially resistant to glucocorticoid-induced epidermal and subcutaneous adipose atrophy which correlated with the protection of CD34+ follicular epithelial stem cells as well as p63+ keratinocyte progenitors in REDD1 knockout epidermis during chronic steroid treatment. At the same time, REDD1 knockout did not affect anti- inflammatory effect of glucocorticoids, as evaluated by ear edema test. Expression profiling revealed that ~ 50% of the glucocorticoid receptor (GR) target genes were not activated in epidermis of REDD1 knockouts, however, the negative effect of glucocorticoids on gene expression was similar to that in w.t. animals. Overall, our findings reveal a novel pathway in GR activation by its target gene/protein REDD1; and indicate an important role of REDD1 in glucocorticoid-induced skin atrophy, and maintenance of the epidermis and subcutaneous adipose. In addition, our findings form the foundation for the development of safer topical glucocorticoid treatment regimens by combining this therapy with REDD1 inhibitors. Seven wk old B6D2 females in the telogen stage of the hair cycle were shaved, and treated 3 days later. Glucocorticoid FA was applied topically (2 ug/animal) in 200 ul acetone to the back skin once or up to four applications every third day as described previously (Chebotaev et al., 2007b). Control animals were treated with acetone only. Skin was harvested 24 h after last FA application or 4-8 h after single FA application as indicated in Figure legends. To evaluate the anti-inflammatory effect of glucocorticoid FA in REDD1 KO and w.t. B6x129 mice, we used ear edema test (Schoepe et al., 2010; Schäcke et al., 2004; Park et al., 2006). Seven wk old female animals were pretreated with FA or vehicle applied to the back of the ear lobe one h before application of nonspecific contact irritant croton oil . Mice were sacrificed and ears were harvested nine hours after CO application, the time point at which we observed maximum ear edema in F1 C57Bl x 129 animals (data not shown). Four mm ear punch biopsies were immediately weighted to assess ear edema. Animals were injected i.p. with bromodeoxyuridine 1 hr before skin was harvested. Total RNA from murine epidermis and whole human skin was isolated with RiboPure kit (Ambion). Total RNA from murine s.c. adipose was isolated with RNeasy Lipid Tissue Kit (Qiagen). The RNA samples were treated with TURBOTM DNase (Ambion). Purity of RNA samples isolated from epidermis and s.c. fat was confirmed by the expression of adipose and keratinocyte cell markers.

Project description:Gene expression profiling of 60 lung adenocarcinoma tumors and their matched histologically normal adjacent lung tissue samples were analyzed using Illumina HumanWG-6 v3.0 expression beadchip. We integrated these data with DNA methylation profiles of the same samples to identify potential DNA methylation regulated genes. Lung cancer is the leading cause of cancer death worldwide and adenocarcinoma is its most common histological subtype. Clinical and molecular evidence indicates that lung adenocarcinoma is a heterogeneous disease, which has important implications for treatment. Here we performed genome-scale DNA methylation profiling using the Illumina Infinium HumanMethylation27 platform on 59 matched lung adenocarcinoma/non-tumor lung samples, with genome-scale verification on an independent set of tissues. We identified 766 genes showing altered DNA methylation between tumors and non-tumor lung. By integrating DNA methylation and mRNA expression data, we identified 164 hypermethylated genes showing concurrent downregulation, and 57 hypomethylated genes showing increased expression. Integrated pathways analysis indicates that these genes are involved in cell differentiation, epithelial to mesenchymal transition, RAS and WNT signaling pathways and cell cycle regulation, among others. Comparison of DNA methylation profiles between lung adenocarcinomas of current and never-smokers showed modest differences, identifying only LGALS4 as significantly hypermethylated and downregulated in smokers. LGALS4, encoding a galactoside-binding protein involved in cell-cell and cell-matrix interactions, was recently shown to be a tumor-suppressor in colorectal cancer. Unsupervised analysis of the DNA methylation data identified two tumor subgroups, one of which showed increased DNA methylation and was significantly associated with KRAS mutation and to a lesser extent, with smoking. Our analysis lays the groundwork for further molecular studies of lung adenocarcinoma by providing new candidate DNA methylation biomarkers for early detection, identifying novel molecular alterations potentially involved in lung adenocarcinoma development/progression, and describing an epigenetic subgroup of lung adenocarcinoma associated with KRAS mutation. 58 lung adenocarcinoma and 58 adjacent non-tumor lung fresh frozen tissues were macrodissected, and total RNA was isolated to be analyzed using the Illumina HumanWG-6 v3.0 expression beadchip.
