Wnt/ß-catenin signaling is strongly implicated in neoplasia, but the role of this pathway in human breast cancer has been controversial. Here, we examined Wnt/ß-catenin pathway activation as a function of breast cancer progression, and tested for a relationship with HER2/neu expression, using a human tissue microarray comprising benign breast tissues, ductal carcinoma in situ (DCIS), and invasi...

Litter size is one of the most important economical traits in sheep breeding industry. In addition to minor genes, litter size is under the influence of major genes. Bone morphogenetic protein 15 (BMP-15), a member of the transforming growth factor beta (TGF-ß) superfamily, which is specifically expressed in oocytes, plays a dramatic role in sheep prolificacy. Reported mutations in this gene ca...

Complexation of celecoxib with ß-cyclodextrin and hydroxypropyl-ß-cyclodextrin in the presence and absence of polyvinylpyrrolidone and the effect of polyvinylpyrrolidone on the solubilizing efficiency of cyclodextrins and on the dissolution rate of celecoxib from the cyclodextrin complexes were investigated. The phase solubility studies indicated the formation of celecoxib-ß-cyclodextrin and ce...

1 Downregulation of Cdk6 kinase activity is crucial for TGF-ß induced growth inhibition (I) ………………………………………………………………………………….38 1.1 TGF-ß growth inhibition is attenuated by overexpression of wild type Cdk6 …………38 1.2 Cyclin D-related kinase activity is maintained in wild type Cdk6-overexpressing cells treated with TGF-ß …..……………………………………………………………….39 1.3 Cdk2-associated kinase activity is partia...

alzheimer’s disease (ad) is a neurodegenerative disease characterized by cognitive and other cns impairments which is increasing worldwide and poses a major public health problem, yet no effective treatments are found and available drugs only alleviate the symptoms temporarily. postmortem analyses on the brains of ad patients and observed lower risk of ad in nsaids users among other studies hav...

Glucocorticoids (GCs) are well known to induce insulin resistance. However, the effect of GCs on insulin secretion has not been well characterized under physiological conditions in human. We here evaluated the effect of GCs on insulin secretion/ß-cell function precisely in a physiological condition. A population-based study of 1,071 Japanese individuals enrolled in the 2014 Iwaki study (390 men...

background: nowadays, the first step in treatment of ectopic pregnancy (ep) is medical treatment. medical treatment with methotrexate (mtx) for ep is safe and effective method without the risks associated with the surgical procedure. but there are controversies between studies for which patients will respond better to medical treatment. objective: the aim of the present study was to investigate...

The multifunctional protein ß-catenin governs as transcription factor the expression of a wide variety of genes relevant for cell proliferation and cell survival. In addition, ß-catenin is localized at the cell membrane and may influence the function of channels. The present study explored the possibility that ß-catenin participates in the regulation of the HERG K(+) channel. To this end, HERG ...

Background: Magnetic resonance imaging (MRI) is becoming increasingly important in axial spondyloarthritis (SpA) due to its unique role early diagnosis, classification, and monitoring of disease (1, 2). It the only assessment tool that has been validated with histological inflammatory cellularity tissue biopsy sacroiliac (SI) joint (3). However, many MRI lesions are not exclusive SpA may occur ...
