Development of the human placenta and its different epithelial trophoblasts is crucial for a successful pregnancy. Besides fusing into a multinuclear syncytium, the exchange surface between mother and fetus, progenitors develop into extravillous trophoblasts invading the maternal uterus and its spiral arteries. Migration into these vessels promotes remodelling and, as a consequence, adaption of...

OBJECTIVE Calcific aortic valve disease is a leading cardiovascular disease in the elderly, and progressive calcification results in the failure of valvular function. Aortic valve interstitial cells (AVICs) from stenotic valves express higher levels of bone morphogenetic protein-2 in response to Toll-like receptor 4 stimulation. We recently found that Toll-like receptor 4 interacts with Notch1 ...

Notch signaling is required for vascular development andtumor angiogenesis. Although inhibition of the Notch ligandDelta-like 4 can restrict tumor growth and disrupt neo-vasculature, the effect of inhibiting Notch receptor function onangiogenesis has yet to be defined. In this study, we generateda soluble form of the Notch1 receptor (Notch1 decoy) andassessed its effect ...

سابقه و هدف: سرطان معده یکی از شایع ترین و کشنده ترین بدخیمی ها در جهان است. اسید رتینوئیک تمام ترانس (atra) به عنوان القاکننده ی تمایز در درمان بسیاری از سرطان ها و به طور ویژه در درمان لوسمی پرومیولوتیک حاد (apl) استفاده می شود. مسیر پیام رسانی سلولی notch نقش مهمی در حفظ تعادل میان تکثیر سلولی و آپوپتوز ایفا می کند. فعالیت نابه جای این مسیر در توسعه و پیشرفت بسیاری از بدخیمی ها از جمله سرطان...

Fixed, paraffin-embedded (FPE) tissues are a potentially rich resource for studying the role of NOTCH1 in cancer and other pathologies, but tests that reliably detect activated NOTCH1 (NICD1) in FPE samples have been lacking. Here, we bridge this gap by developing an immunohistochemical (IHC) stain that detects a neoepitope created by the proteolytic cleavage event that activates NOTCH1. Follow...

BACKGROUND AND PURPOSE Calcific aortic stenosis is a chronic inflammatory disease, and aortic valve interstitial cells (AVIC) play an important role in valvular inflammation. Whereas AVIC from stenotic aortic valves exhibit an augmented response to Toll-like receptor 4 (TLR4) stimulation, the underlying mechanism is unclear. This study tested the hypothesis that an excessive cross-talk between ...

BACKGROUND AND AIMS According to recent findings, some tumor cells function as endothelial progenitor cells to initiate tumor vasculogenesis, known as "vasculogenic mimicry" (VM). Notch1, the key regulator of vasculogenesis and embryonic differentiation, has shown a correlation with a poor prognosis in hepatocellular carcinoma (HCC). We attempted to elucidate the relationship between Notch1 and...

BACKGROUND The receptors of Notch family play an important role in controlling the development, differentiation, and function of multiple cell types. The aim of this study is to investigate the role of Notch1 signaling upon immune suppression induced by melanoma cells. METHODS Melanoma cell line B16 cells were transfected by lentivirus containing mouse Notch1 gene or Notch1 shRNA to generate ...

BACKGROUND Notch signaling influences binary cell fate decisions in a variety of tissues. The Notch1 receptor is widely expressed during embryogenesis and is essential for embryonic development. Loss of global Notch1 function results in early embryonic lethality, but the cell type responsible for this defect is not known. Here, we identify the endothelium as the primary target tissue affected b...

Gastric carcinoma is the third leading cause of lethal cancer worldwide. Previous studies showed that Notch1 receptor intracellular domain (N1IC), the activated form of Notch1 receptor, promotes gastric cancer progression. It has been demonstrated that a significant cross-talk interplays between Notch pathways and microRNAs (miRNAs) in controlling tumorigenesis. This study identified an introni...
