Difenoconazole, as one of the most widely used triazole fungicides, is applied to protect crops, fruits, and vegetables. It has been reported that difenoconazole can enter the environment and impair aquatic organisms, but whether difenoconazole can disrupt the growth hormone (GH) balance in adult zebrafish (Danio rerio) is still unclear. In this study, adult female and male zebrafish were exposed to difenoconazole (0, 5, 50, and 500µg/L) for seven days. The results revealed that the bioaccumulation of difenoconazole and its primary metabolite difenoconazole alcohol in females were both larger than that in males...

INTRODUCTION: Adiponectin (APN) is adipose tissue-derived hormone influencing energy metabolism. Growth hormone deficiency (GHD) may contribute to the development of disturbances in the hormonal function of adipose tissue (AT), and many disorders observed in untreated patients with GHD coincides with these contributed to low serum APN levels. OBJECTIVES: The assessment of serum adiponectin levels in adolescents and young adults with severe or partial GHD and analysis of relationships between serum APN and GH/IGF-1 axis function impairment as well as cardiometabolic risk factors...

Lifespan in many organisms, including Drosophila melanogaster, can be increased by reduced insulin-IGF-like signaling (IIS) or by changes in diet. Most studies testing whether IIS is involved in diet-mediated lifespan extension employ only a few diets, but recent data shows that a broad range of nutritional environments is required. Here, we present lifespan data of long-lived Drosophila, lacking three of the eight insulin-like peptides [Drosophila insulin-like peptides 2,3,5 (dilp2-3,5)] on nine different diets that surround the optimum for lifespan...

Mutation in the insulin-like growth factor-1 receptor (IGF1R) gene is a rare cause for intrauterine and postnatal growth disorders. Patients identified with IGF1R mutations present with either normal or impaired glucose tolerance. None of the cases described so far showed hypoglycemia. We aimed to identify the genetic basis for small for gestational age, short stature and hypoglycemia over three generations in one family. The proband, a 9-year-old male presented in infancy with recurrent hypoglycemic episodes, symmetric intrauterine growth retardation and postnatal growth retardation...

BACKGROUND & AIMS: We previously described in cirrhosis and aging, both conditions of IGF-1 deficiency, a clear hepatic mitochondrial dysfunction with increased oxidative damage. In both conditions, the hepatic mitochondrial function was improved with low doses of IGF-1. The aim of this work was to explore if the only mere IGF-1 partial deficiency, without any exogenous insult, is responsible for hepatic mitochondrial dysfunction. METHODS: Heterozygous (igf1(+/-)) mice were divided into two groups: untreated and treated mice with low doses of IGF-1...

PURPOSE: The insulin-like growth factor (IGF) system is modifiable by diet and lifestyle, and has been linked to prostate cancer development and progression. METHODS: We conducted a prospective cohort study of 621 men diagnosed with localized prostate cancer to investigate the associations of dietary and lifestyle changes with post-diagnosis circulating levels of IGF-I and IGFBP-3. We used analysis of covariance to estimate the associations, controlling for baseline IGF-I or IGFBP-3, respectively...

Insulin-like Growth Factor 1 (IGF-1) is associated with cardiovascular disease, itself a risk factor for hearing impairment, and, in animal studies, molecular evidence suggests a role for IGF-1 in hearing function. However, the link between IGF-1 and the occurrence of hearing impairment is untested in population-based studies of humans. A total of 4390 participants aged ≥50 y (mean [SD] age 64.2 [8.0] years at baseline, 55% women) from the English Longitudinal Study of Ageing provided serum levels of IGF-1 in 2008 and again in 2012...

Growth factor signaling via insulin receptor (IR) and IGF-1 receptor (IGF1R) plays several important roles in the pathogenesis of metabolic syndrome and diabetes. OSI-906 (linsitinib), an anti-tumor drug, is an orally bioavailable dual inhibitor of IR and IGF1R. To investigate the recovery from metabolic changes induced by the acute inhibition of IR and IGF1R in adult mice, mice were treated with OSI-906 or a vehicle for 7 days and the results were analyzed on the last day of injection (Day 7) or after 7 or 21 days of withdrawal (Day 14 or Day 28)...

BACKGROUND CONTEXT: The process of linear growth is driven by axial elongation of both long bones and vertebral bodies and accomplished by enchondral ossification. Differences in regulation between the two skeletal sites are mirrored clinically by the age course in body proportions. Whereas growth plates in long bones can easily be discriminated, vertebral growth plates are part of the cartilaginous endplate, which typically shows important species differences. PURPOSE: To describe and compare histological, histomorphometric and regulatory characteristics in the growth plates of the spine and long bones in a porcine model...

In rats, learning and memory performance decline during normal aging, which makes this rodent species a suitable model to evaluate therapeutic strategies. In aging rats, insulin-like growth factor-I (IGF-I), is known to significantly improve spatial memory accuracy as compared to control counterparts. A constellation of gene expression changes underlie the hippocampal phenotype of aging but no studies on the effects of IGF-I on the hippocampal transcriptome of old rodents have been documented. Here, we assessed the effects of IGF-I gene therapy on spatial memory performance in old female rats and compared them with changes in the hippocampal transcriptome...

Polycystic kidney disease (PKD) is a prevalent disorder characterized by renal cysts that lead to kidney failure. Various signaling pathways have been targeted to stop disease progression, but most interventions still focus on alleviating PKD-associated symptoms. The mechanistic complexity of the disease, as well as the lack of functional in vitro assays for compound testing, has made drug discovery for PKD challenging. To identify modulators of PKD, Pkd1(-/-) kidney tubule epithelial cells were applied to a scalable and automated 3D cyst culture model for compound screening, followed by phenotypic profiling to determine compound efficacy...

Osteosarcoma is a primary malignancy of bone that affects children and adults. Here, we present the largest sequencing study of osteosarcoma to date, comprising 112 childhood and adult tumours encompassing all major histological subtypes. A key finding of our study is the identification of mutations in insulin-like growth factor (IGF) signalling genes in 8/112 (7%) of cases. We validate this observation using fluorescence in situ hybridization (FISH) in an additional 87 osteosarcomas, with IGF1 receptor (IGF1R) amplification observed in 14% of tumours...

Our objectives were to evaluate the effects of the 1) season, and 2) postmortem changes on serum biochemistries related with metabolism in Pyrenean chamois (Rupicapra pyrenaica pyrenaica). Serum samples from 98 animals obtained from 2009 to 2012 were included. To investigate seasonal influences on blood parameters, the Pyrenean chamois were captured in drive-nets during the feed abundant (FA; n=32) and food deficient (FD; n=35) seasons. To evaluate the possible differences in biochemistry analytes when sampling live or dead animals, we used serum samples from 32 captured animals and 31 dead animals (obtained during controlled hunting) in the FA season...

Overexpression of HER2 has been reported in around 25% of human breast cancers. Despite recent advances in HER2 targeted therapy, many patients still experience primary and secondary resistance to such treatments, the mechanisms for which are poorly understood. Here, we investigated the sensitivity of a panel of breast cancer cell lines to treatment with various types of HER-family inhibitors alone or in combination with other tyrosine kinase inhibitors or chemotherapeutic agents. We found that treatment with the second-generation irreversible HER-family inhibitors, particularly afatinib and neratinib, were more effective than treatment with the first-generation reversible inhibitors in inhibiting growth, migration and downstream cell signalling in breast cancer cells...

Purpose: Myxoid liposarcoma is an aggressive disease with particular propensity to develop hematogenic metastases. Over 90% of myxoid liposarcoma are characterized by a reciprocal t(12;16)(q13;p11) translocation. The resulting chimeric FUS-DDIT3 fusion protein plays a crucial role in myxoid liposarcoma pathogenesis; however, its specific impact on oncogenic signaling pathways remains to be substantiated. We here investigate the functional role of FUS‑DDIT3 in IGF-IR/PI3K/Akt signaling driving myxoid liposarcoma pathogenesis...

Accurately establishing the relationships among individuals lays the foundation for genetic analyses such as genome-wide association studies and identification of selection signatures. Of particular interest to the poultry industry are estimates of genetic merit based on molecular data. These estimates can be commercially exploited in marker-assisted breeding programs to accelerate genetic improvement. Here, we test the utility of a new method we have recently developed to estimate animal relatedness and applied it to genetic parameter estimation in commercial broilers...
