As a tool for measuring the aging process, life span has been invaluable in dissecting the genes that modulate longevity. Studies over the past few decades have identified several hundred genes that can modify life span in model organisms such as yeast, worms, and flies. Yet, despite this vast amount of research, we still do not fully understand how the genes that affect life span influence how...

To investigate the effects and potential mechanisms of chicoric acid (CA) on LPS-induced inflammatory response in A549 cells. 0–800 μM CA was added to cells determine toxicity using MTT assay. Then, 2 μg/mL LPS 50 were simultaneously CA. In order miR-130a-3p IGF-1 cells, infected with inhibitor si RNA IGF-1. The levels cytokines such as IL-1β, IL-6, TNF-α measured by real-time RT-PCR enzyme-lin...

conclusions our findings indicated a lower level of both omentin-1 and igf-1 in women with mets; this might play a role in the pathogenesis of mets. furthermore, the main finding of the current investigation was the association between omentin, visfatin and igf-1; however determining the molecular mechanism of the observed relationships needs further studies. results significantly lower levels ...

A role for insulin-like growth factors (IGF) in autocrine or paracrine growth stimulation of tumor cells has been proposed for tumors of different origins. We have studied IGF gene expression in human uterus smooth muscle (myometrium) and in a panel of benign (leiomyoma) and malignant (leiomyosarcoma) smooth muscle tumors. Using RNA transfer blot analysis we could demonstrate that in smooth mus...

Insulin-like growth factor I (IGF I), a potent growth factor in vitro, is present in blood and in multiple tissues and is a major mediator of the effects of growth hormone on postnatal growth. IGF I is internalized and retained largely intact in cultured vascular endothelial cells. Neovasculature transiently expresses IGF I immunoreactivity, but it is not known whether this represents internali...

Insulin and the insulin-like growth factors (IGF)-I and -II are closely related peptides important for regulation of metabolism, growth, differentiation, and development. The IGFs exert their main effects through the IGF-I receptor. Although the insulin receptor is the main physiological receptor for insulin, this peptide hormone can also bind at higher concentrations to the IGF-I receptor and ...

Persistent hyperglycemia resulting from diabetes mellitus causes microvascular lesions and long-term diabetic complications, such as nephropathy. The aim of the study was to analyze levels insulin-like growth factors (IGFs), their carrier proteins (IGFBP), markers kidney tissue damage (IL-18, L-FABP, cystatin C, NGAL, KIM-1) in male rats with mellitus, tumor growth, combination. Materials metho...
