(Submitter supplied) We here used the technology of RNA interference or selective treatment of the ESR1 and cDNA microarrays to reconstruct a network between genes known to be disregulated in ER-positive breast cancer diseases. Therefor single genes of high importance were silenced and the effect of this pertubation was measured with cDNA microarrays. Keywords: Network Reconstruction, RNAi, siRNA, Interaction Network

(Submitter supplied) Specific types of human papillomaviruses (HPVs) cause cervical cancer, the second most common tumor in females worldwide. Both cellular transformation and the maintenance of the oncogenic phenotype of HPV-positive tumor cells are linked to the expression of the viral E6 and E7 oncogenes. In order to identify downstream cellular target genes for the viral oncoproteins, we silenced endogenous E6 and E7 expression in HPV-positive HeLa cells by RNA interference (RNAi). more...

(Submitter supplied) MicroRNAs (miRNAs) are small non-coding RNAs that repress their target mRNAs by complementary base pairing and induction of the RNAi pathway. It has been shown that miRNA expression can be regulated by DNA methylation and it has been suggested that altered miRNA gene methylation might contribute to human tumorigenesis. In this study, we show that the human let-7a-3 gene on chromosome 22q13.31 is associated with a CpG island. more...

(Submitter supplied) Alterations in DNA-methylation are a hallmark of human tumor cells. DNMT1 is expressed in three different splice variants and exhibits considerable preference for hemimethylated DNA and is therefore referred to as the maintenance methylase. DNMT3b is generally considered to be responsible for de novo methylation during embryonic development and probably also during tumor development. Recent studies using somatic knock-out of DNA-methyltransferases have shown a reduction in overall methylation and a re-expression of tumor suppressor genes. more...

(Submitter supplied) Dilated cardiomyopathy (DCM) is a common cause of heart failure and a leading cause of cardiac transplantation in western countries. The robust predictive expression profile of cardiomyopathic and NF hearts as well as the functional classification can help to identify promising candidates for DCM and may improve the early diagnosis of cardiomyopathy.

Comparison of septal myocardial tissue samples from 13 patients with dilated cardiomyopathy (DCM) to those from 15 patients with non-failing (NF) hearts. DCM is a common cause of heart failure. Results contribute to the identification of a gene expression signature for DCM.

(Submitter supplied) Pigmented villonodular synovitis (PVNS) represents a rare group of lesions with morphological features suggesting an inflammatory as well as a neoplastic nature. Rheumatoid arthritis (RA) is characterized by a chronic inflammation of the synovial tissue and a tumor-like proliferation (TLP) of synovial stroma cells. Osteoarthritis (OA) shows modest inflammatory infiltrates and no TLP. All three diseases result in a progressive destruction of affected joints and remain a diagnostic difficulty because of nonspecific symptoms. more...
