background: this research studies the effects of activation and inhibition of wnt3a signaling pathway in buffalo (bubalus bubalis) embryonic stem (es) cell-like cells. materials and methods: to carry on this experimental study, the effects of activation and inhibition of wnt3a signaling in buffalo es cell-like cells were examined using bio (0.5 mm) combined with wnt3a (200 ng/ml), as an activat...

Inhibition of VEGF signaling can promote lymph node metastasis in preclinical models, but the mechanism is not fully understood, and successful methods of prevention have not been found. Signaling of hepatocyte growth factor (HGF) and its receptor c-Met can promote the growth of lymphatics and metastasis of some tumors. We sought to explore the contributions of c-Met signaling to lymph node met...

Emerin is the inner nuclear membrane protein involved in maintaining mechanical integrity of membrane. Mutations EMD encoding emerin cause Emery–Dreifuss muscular dystrophy (EDMD). Evidence accumulating that regulation specific gene expression associated with this disease, but exact function has not been fully elucidated. Here, we show downregulates Signal transducer and activators transcriptio...

background: coronary artery disease (cad) is the major cause of mortality and morbidity worldwide. the aim of this study was to explore the effect of resveratrol (res) on canonical β-catenin/wnt and forkhead box o (foxo) pathways in cad patients.method: we performed this study on 10 metabolic syndrome patients with three-vessel cad and 10 sex-aged matched healthy subjects. the effects of res on...

Cell-cell communication by juxtacrine signaling plays a key role in the development of the nervous system, from cell fate determination through axonal guidance to synaptogenesis. Interestingly, several juxtacrine signaling systems exhibit an inhibitory interaction between receptors and ligands in the same cell, termed cis inhibition. These include the Notch, semaphorin and ephrin signaling syst...

Prostate cancer is characterized by its dependence on androgen receptor (AR) and frequent activation of PI3K signaling. We find that AR transcriptional output is decreased in human and murine tumors with PTEN deletion and that PI3K pathway inhibition activates AR signaling by relieving feedback inhibition of HER kinases. Similarly, AR inhibition activates AKT signaling by reducing levels of the...

in this paper, a general introduction is given, presenting the overactive bladder syndrome (oab) and its impact on the quality of life and economical burden in patients affected. moreover, the anatomy, physiology and histology of the lower urinary tract are discussed, followed by a brief overview on the possible role of prostaglandin (pg) and phosphodiesterase type 5 (pde5) in the urinary bladd...

Background: Rhabdomyosarcoma (RMS) is the most common soft-tissue sarcoma of childhood, and RAS pathway mutations are known driver in majority fusion-negative (FN) RMS. Recent studies have demonstrated that HRAS enriched infant cases FN-RMS can be associated with an aggressive clinical course inferior outcomes. Using HRAS-mutant RMS cell lines xenograft models, we tipifarnib (farnesyl transfera...

traumatic brain injury (tbi) results from a sudden and external physical impact to the head, and often leads to motor and cognitive impairment. using tissue engineering strategies, we aimed to review aspects of extra cellular matrix (ecm) based scaffold that could be delivered to the injured brain. the ecm is produced intracellularly and secreted to form a dense network of proteins and glycans,...
