background:   objective: to understand the changes of mirnas in endometriosis.   materials and methods: with real-time rt-pcr, we investigated the mir-143 and mir-145 expression in eutopic (eu, n=2) and ectopic endometrium (ec, n=11) (from women with endometriosis) (as well as eu+ec, n=11), along with the normal endometrium (en, n=22) (from women without endometriosis, but with leiomyoma). resu...

tubal ectopic hydatidiform mole is an uncommon but very important complication of pregnancy. the clinical manifestation is the same as ectopic pregnancy and in all of the cases management was the same as tubal ectopic pregnancy. we present a case of tubal ectopic pregnancy that after laparotomy and salpingectomy, pathologic examination reported hydatidiform mole within ectopic gestational tissu...

Ectopic Myc expression plays a key role in human tumorigenesis, and Myc dose-dependent tumorigenesis has been well established in transgenic mice, but the Myc target genes that are dependent on Myc levels have not been well characterized. In this regard, we used the human P493-6 B cells, which have a preneoplastic state dependent on the Epstein-Barr viral EBNA2 protein and a neoplastic state wi...

Human somatic cells have a limited life span in vitro. Upon aging and with each cell division, shortening of telomeres occurs, which eventually will lead to cell cycle arrest. Ectopic hTERT expression has been shown to extend the life span of human T cells by preventing this telomere erosion. In the present study, we have shown that ectopic hTERT expression extends the life span of CD4+ T helpe...

ectopic thyroid tissue (ett) is a rare entity and a challenging differential diagnosis. this is a report of a case of a mediastinal mass that was found to be an ectopic mediastinal thyroid tissue, in a 77-year-old woman who was admitted to our hospital for breast cancer management. the mediastinal mass was identified in the postsurgical computed tomography (ct) scan of the chest and was suspect...

Partial or complete mole affects one in 1000  pregnancies.Partial mole is a rare form of ectopic pregnancy. There was a married woman,gravid 4,parity 1,abortion 1,and she had past medical history 0f right ectopic pregnancy.she had left ectopic pregnancy and was treated by laparascopic left salpyngectomy after failure of intramascular methotrexate treatment.After surgery  the pathology exam show...

Ectopic expression of peripherally restricted Ags by medullary thymic epithelial cells (mTECs) is associated with negative selection. Autoimmune regulator (AIRE) is considered to be the master regulator of these Ags. We show in this study that the ectopic expression of type II collagen (CII) in mTECs and the corresponding central tolerance to CII are AIRE independent but lymphotoxin dependent. ...

We isolated three recessive mutants of Arabidopsis (Arabidopsis thaliana) showing ectopic expression of the xylem-specific marker, pAtxyn3::YFP. Genetic analysis indicated that the phenotypes were caused by mutations in three different genes, designated Abnormal Tracheary Element formation-related gene expression (ate1-3). The ate1 mutants showed a normal DR5::GUS gene expression pattern, and t...

Endometriosis is characterised by the growth of ectopic lesions at multiple locations outside the uterine cavity and may be considered a collection of distinct but related conditions. The exact aetiology of endometriosis is still not clear although a role for inflammation is increasingly accepted. We therefore investigated the inflammatory activity of eutopic tissue and that of the matching ect...

The transcription factor PAX5 is a critical regulator of B-cell commitment and development. Although normally not expressed in myeloid progenitors, PAX5 has recently been shown to be frequently expressed in myeloid malignancies and to suppress expression of myeloid differentiation genes, compatible with an effect on the differentiation or maintenance of myeloid progenitors. However, previous st...
