Notch signaling is required for vascular development and tumor angiogenesis. Although inhibition of the Notch ligand Delta-like 4 can restrict tumor growth and disrupt neovasculature, the effect of inhibiting Notch receptor function on angiogenesis has yet to be defined. In this study, we generated a soluble form of the Notch1 receptor (Notch1 decoy) and assessed its effect on angiogenesis in v...
During early limb development, distal tip ectoderm is induced by the underlying mesenchyme to form the apical ectodermal ridge. Subsequent limb growth and patterning depend on reciprocal signaling between the mesenchyme and ridge. Mice that are homozygous for mutations at the limb deformity (ld) locus do not form a proper ridge and the anteroposterior axis of the limb is shortened. Skeletal ana...
The multi-kinase inhibitor sorafenib is clinically approved for the treatment of patients with advanced hepatocellular carcinoma (HCC). We previously reported that fibroblast growth factor 3 and 4 (FGF3/FGF4) amplification is a predictor of a response to sorafenib. This study aims to analyze the relationship between FGF-FGF receptor (FGFR) genetic alterations and the response to sorafenib. Form...
Oct4 and Sox2 regulate the expression of target genes such as Nanog, Fgf4, and Utf1, by binding to their respective regulatory motifs. Their functional cooperation is reflected in their ability to heterodimerize on adjacent cis regulatory motifs, the composite Sox/Oct motif. Given that Oct4 and Sox2 regulate many developmental genes, a quantitative analysis of their synergistic action on differ...
The biological consequences of constitutive fibroblast growth factor-4 (fgf4) expression have been analysed during anterior CNS development of mouse chimeric embryos. Severe mutant embryos exhibit exencephaly, absence of eye development and anomalous differentiation of the neuroepithelium. These embryos also show ectopic limb buds resembling the early phases of limb development. Because our res...
By means of the tumorigenicity assay applying DNA from a patient with a gastric carcinoma (MA) we have already reported the identification of the putative oncogene myeov. In addition we have shown its involvement in t(11;14)-positive multiple myelomas and amplifications of breast tumours and esophageal carcinomas. The failure of myeov cDNA to induce tumour formation in NIH/3T3 cells prompted us...
Chondrodystrophy in dogs is defined by dysplastic, shortened long bones and premature degeneration and calcification of intervertebral discs. Independent genome-wide association analyses for skeletal dysplasia (short limbs) within a single breed (PBonferroni = 0.01) and intervertebral disc disease (IVDD) across breeds (PBonferroni = 4.0 × 10-10) both identified a significant association to the ...
Hepatic progenitor cells (HPCs) are a potential cell source for liver cell transplantation but do not function like mature liver cells. We sought an effective and reliable method to induce HPC maturation. An immortalized HP14.5 albumin promoter-driven Gaussian luciferase (ALB-GLuc) cell line was established from HPCs isolated from fetal mouse liver of post coitus day 14.5 mice to investigate th...
BACKGROUND MicroRNA 194 is involved in the differentiation of various types of cells, such as adipose derived stem cells, human embryonic stem cells, and bone marrow mesenchymal stem cells. Previously, we found that miR-194 was highly expressed in the inner ear sensory patch and neurons in mice embryos. However, the role of miR-194 in the development of the inner ear and its underlying mechanis...
زمینه و هدف: مطالعات نشان داده است هرچند نرخ لانهگزینی بلاستوسیست در مقایسه با مراحل قبل، بالاتر است، اما در مقابل، نرخ بقای رویانهای ذوبشده در این مرحله نسبت به مراحل دیگر پایینتر بوده که میتواند ناشی از وجود حفره پر از مایع بلاستوسل و افزایش احتمال تشکیل کریستالهای یخ باشد. همچنین وجود این مایع میتواند بهعنوان مانعی در مقابل نفوذ مواد محافظ سرما به داخل جنین عمل کند. در این مطالعه با ...
