Insulin-like growth factor 1 (IGF-1) is involved in the regulation of brain development and has been suggested as an autocrine stimulator of brain tumor cell proliferation. This study demonstrates the expression of IGF-1 in tumor tissue from human gliomas and one esthesioneuroblastoma. Using immunohistochemistry, expression of an IGF-1-like peptide was localized in tumor cells of 6 of the 9 gli...

baluchi sheep is considered as the most common breed in iran, constituting about 30% of total sheep population, approximately 15 million heads. this research was designed to study the incidence of mutation in two loci of igf-i (exon 3) and adrb3 (intron) along with their association with body weight traits in baluchi sheep population. following dna extraction from 190 baluchi sheep, two pairs o...

Conflicting data on the role of metabolic syndrome (MS) in development hepatocellular carcinoma (HCC) require studies influence molecular factors that are important HCC MS, which was goal our review. Publications (scientific articles and reviews) over past 10 years were studied analyzed using databases Web Science, Scopus, PubMed, RSCI. The terms used for search “metabolic non-alcoholic fatty l...

Background: Intra-articular injection of Platelet-rich plasma (PRP) is an effective method for the treatment of patientswith knee osteoarthritis (OA). This study aimed to assess the effects of PRP injection on OA, based on gene expressionanalysis.Methods: A sample of 30 subjects with knee OA was asked to complete the Persian versions of the Intermittent andConstant Osteo...

Growth of the fetal heart involves cardiomyocyte enlargement, division, and maturation. Insulin-like growth factor-1 (IGF-1) is implicated in many aspects of growth and is likely to be important in developmental heart growth. IGF-1 stimulates the IGF-1 receptor (IGF1R) and downstream signaling pathways, including extracellular signal-regulated kinase (ERK) and phosphoinositol-3 kinase (PI3K). W...

Conflicting evidence exists on the relationship between blood pressure (BP) and insulin-like growth factor-1 (IGF-1). We reviewed available articles and pooled extrapolated regression coefficients for the association between BP and total IGF-1 as reported in the literature and included additional data from 912 individuals from the general population. We identified 20 studies including 11 704 su...

conclusions igf-1 has the most significant effect on intrauterine growth. acylated ghrelin is detectable in cord blood and correlated with birth weight, suggesting a role in intrauterine development, but its level is not affected by intrauterine growth retardation. results no significant differences were observed in ghrelin and gh concentrations between sga and aga infants. however, igf-1 level...

OBJECTIVE To investigate the immunohistochemical localization of insulin-like growth factor 1 (IGF-1) and IGF-1 receptor (IGF-1R) in archival specimens of sporadic schwannoma. METHOD This study retrospectively analysed the immunolocalization of IGF-1 and IGF-1R in schwannoma specimens collected from all patients with sporadic schwannoma that were treated by two institutions in Japan. The stud...
