(Submitter supplied) Lung cancers are a heterogeneous group of diseases with respect to biology and clinical behavior. Currently, diagnosis and classification are based on histological morphology and immunohistological methods for discrimination between two main histologic groups: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) which account for 20% and 80% of lung carcinomas, respectively. NSCLCs, which are divided into the three major subtypes adenocarcinoma, squamous cell carcinoma and dedifferentiated large cell carcinoma, show different characteristics such as the expression of certain keratins or production of mucin and lack of neuroedocrine differentiation. more...

(Submitter supplied) Adenocarcinoma in situ (AIS) is considered an intermediate step in the progression of normal lung tissue to invasive adenocarcinoma. However, the molecular mechanisms underlying this progression remain to be fully elucidated due to difficulties in obtaining and preserving clinical samples for downstream analyses. Formalin fixation and paraffin embedding (FFPE) is a tissue preservation system that is widely used as a means for long-term storage. more...

(Submitter supplied) The molecular mechanisms whereby hepatitis B virus (HBV) induces hepatocellular carcinoma (HCC) remain elusive. We used genomic and molecular techniques to investigate host-virus interactions by mapping the entire liver of patients with HCC. We compared the gene signature of whole liver tissue (WLT) versus laser capture-microdissected (LCM) hepatocytes with intrahepatic expression of HBV. Gene expression profiling was performed on up to 17 WLT specimens obtained at various distances from the tumor center in individual livers of 11 patients with HCC and on selected LCM samples. more...

(Submitter supplied) In this study, we explored the molecular basis of site-specific metastasis of breast cancer to the lungs in a clinically relevant model based on the JygMC(A) cell line. In this dataset, we include expression data from JygMC(A) primary mammary tumors (carcinoma and EMT-like areas), lung metastases, normal mammary glands and normal lung parenchyma.

(Submitter supplied) Background: Lung-resident immune cells around local environment of non-small cell lung cancers implicate the balance of pro- and anti-tumor immunity; however the transcriptomic profiles of these cells remain poorly understood. Methods: Transcriptomic microarray study of lung-resident immune cells, harvested by bronchoalveolar lavage, was performed in the discovery group and the findings were validated in published microarray datasets and in an independent group by RT-qPCR

(Submitter supplied) Melanoma accounts for the majority of skin cancer related mortality. In-depth molecular analysis of neoplastic melanocytes in whole tissue biopsies is diluted by the inflammatory infiltration, which may obscure gene signatures specific to neoplastic cells. Thus, a method is needed to precisely uncover molecular changes specific to tumor cells from a limited sample of primary melanomas.

(Submitter supplied) The prostate represents a complex mix of cell types and there is a need to analyze distinct cell populations to better understand their potential interactions. This study of cell-type specific gene expression patterns will contribute to understanding of how tumor epithelial cells may be affected by adjacent interstitial stromal cells within the tumor microenvirnonment. LCM and microarray analysis were used to identify gene expression patterns in prostate cancer epithelial and interstitial stromal cell populations. more...

(Submitter supplied) Using a multiorgan metastasis model of human NSCLC cells (ACC-LC319/bone2) in NK cell-depleted SCID mice, we attempted to identify genes involved in the organ-selective nature of lung cancer-metastasis process, especially bone metastasis. Genome-wide gene expression profile of 15 metastatic lesions from three organs (bone, lung and liver) in this mouse model revealed lot of genes that seemed to reflect the organ specificity of metastatic cells. more...

(Submitter supplied) To better understand the interaction between tumor cells and their microenvironment with regard to mechanisms of invasion, total RNA was isolated from the inner-tumor, tumor invasion front, adjacent lung and distant normal lung tissue from 18 patients with squamous cell lung carcinoma using punch-aided laser capture microdissection. Comprehensive mRNA expression profiles were obtained from microarray expreiments and statistical analyses revealed extensive changes in gene expression when comparing the inner tumor and tumor front with the normal lung and lung front. more...

(Submitter supplied) Previous work has shown that lung tumors and normal-appearing adjacent lung tissues share specific abnormalities that may be highly pertinent to the pathogenesis of lung cancer. However, the global and molecular adjacent airway field cancerization in non-small cell lung cancer (NSCLC) has not been characterized before. We sought to understand the transcriptomic architecture of the adjacent airway field canerization, in conjunction with tumors, to gain additional insights into the lung cancer biology and oncogenesis.

(Submitter supplied) In this study, a unique geographical tissue sampling collection was obtained from patients that underwent curative lobectomy for stage I pulmonary adenocarcinoma. Tumor and non-tumor lung samples located at 0, 2, 4, and 6 cm away from the tumor were collected. Whole genome gene expression profiling was performed on all samples (n = 5 specimens x 12 patients = 60). Analyses were carried out to identify genes differentially expressed in tumor compared to adjacent non-tumor lung tissues at different distances from the tumor as well as to identify stable and transient genes in non-tumor tissues with respect to tumor proximity.

(Submitter supplied) The tumor microenvironment strongly influences cancer development, progression and metastasis. The role of carcinoma-associated fibroblasts (CAFs) in these processes and their clinical impact has not been studied systematically in non-small cell lung carcinoma (NSCLC). We established primary cultures of CAFs and matched normal fibroblasts (NFs) from 15 resected NSCLC. We demonstrate that CAFs have greater ability than NFs to enhance the tumorigenicity of lung cancer cell lines. more...

(Submitter supplied) Background Correct achievement of early ovarian folliculogenesis is a crucial phase for further ovarian function. This process is closely regulated by cell-cell interactions and coordinated expression of genes from oocyte and granulosa cells. But, despite of the large number of studies, little is known about the precise gene expression patterns driving early folliculogenesis. The experimental limitations concerned the very small size of these follicles and the mixture of the different developmental stages within an ovary that make the study of isolated follicular components much more difficult. more...
