Aim Insulin-like growth factor 1 (IGF-1), which is primarily produced in hepatocytes and associated with liver functional reserve, plays a crucial role the pathological condition of cirrhosis. This study aimed to investigate usefulness serum IGF-1 levels for predicting long-term prognosis decompensation development patients Methods We retrospectively evaluated 148 cirrhosis divided them into th...

It is well known that insulin-like growth factor-1 receptor (IGF-1R) plays a crucial role in proliferation and survival of transformed cells. Overexpression of IGF-1R in certain tumors has been reported, but there is still little known about its importance in vivo. Here, we evaluated the IGF-1R levels in 35 human synovial sarcoma tumors by Western blot and reverse transcriptase-PCR. In 18 of th...

The insulin-like growth factors are single-chain polypeptides which promote cell multiplication in vitro. Their role in mammalian development is uncertain, although they have been implicated as modulators of cell growth and differentiation. We present evidence that the human IGF-II gene has at least two promoters, and their expression may be developmentally controlled in the liver. Most of the ...

BACKGROUND Luteolin is a 3',4',5,7-tetrahydroxyflavone found in various fruits and vegetables. We have shown previously that luteolin reduces HT-29 cell growth by inducing apoptosis and cell cycle arrest. The objective of this study was to examine whether luteolin downregulates the insulin-like growth factor-I receptor (IGF-IR) signaling pathway in HT-29 cells. METHODS In order to assess the ...

Obesity is an important factor that threatens human health. The occurrence of many chronic diseases related to obesity, and cognitive function decline often occurs with the onset obesity. With further prevalence it bound lead a wider range dysfunction (ORCD). Therefore, crucial suppress ORCD through intervention. In this regard, exercise has been shown be effective in preventing obesity improvi...

The mouse insulin-like growth factor II (IGF-II) gene encodes a polypeptide that plays a role in embryonic growth. We have examined the temporal and spatial pattern of expression of this gene in sections of the mouse conceptus between embryonic days 4.0 and 8.5 by in situ hybridization. Abundant IGF-II transcripts were detected in all the trophectodermal derivatives, after implantation. Labelin...

results 100 patients with cirrhosis with a male to female ratio of 63:37 and a mean age of 44.4 ± 15 years were enrolled in the study. median igf-1 was 92.95 ± 91.51 ng/ml. 14 patients (14%) had igf-1 within normal limits while 86 patients (86%) had abnormal igf-1 levels. in all patients the correlation coefficient between igf-1 and meld was -0.317 (p = 0.001) and 0.478 between igf-1 and child-...

The components of the insulin-like growth factor (IGF) axis have been investigated in the normal human thymus. Using ribonuclease protection assays (RPA), IGF-II transcripts were detected in the normal human thymus. By reverse transcriptase polymerase chain reaction (RT-PCR) analyses, promoters P3 and P4 were found to be active in the transcription of IGF2 gene within human thymic epithelial ce...

Transgenic mice that overexpress insulin-like growth factor-1 (IGF-I) specifically in skeletal muscle have generated much information about the role of this factor for muscle growth and remodelling and provide insight for therapeutic applications of IGF-I for different pathological states and ageing. However, difficulties arise when attempting to critically compare the significance of data obta...
