maintains NSC numbers by promoting cell division (via the IGF-I
receptor), whereas IGF-II drives the expression of proteins essential for NSC self-renewal and 'sternness' (via the insulin receptor).
Conclusion: Baseline IGF-I
levels may be used to predict response to levosimendan treatment in patients hospitalized for decompensated HE (Anadolu Kardiyol Derg 2011; 11.
Assessing skeletal maturity by using blood spot insulin-like growth factor I (IGF-I
Another condition with serum low IGF-I
levels is Laron syndrome, the most common type of GH resistance.
We began studying the role of IGF-I
in Leishmania infection based on the observation that IGF-I
is produced by different cell types, including macrophages, and is present in the skin, which is the tissue where the parasite initiates infection .
Patients were included if they had GHD defined by peak GH level <10 ng/mL on both arginine, clonidine, and glucagon stimulation testing or multiple pituitary hormone deficiencies (MPHD) with low GH or IGF-I
concentrations based on age, sex, and reference range documented GH treatment during the study period, and measurements of IGF-I
and IGF-Iz during the study period.
Measurements of GH and IGF-I
are used as complementary markers in both the diagnosis and long-term monitoring of treatment of acromegaly (4, 5).

Genomic DNA was extracted from growing feather pulp using standard Phenol Chloroform Isoamylalcohol (PCI) method and the polymorphism of IGF-I
gene was detected by PCR-RFLP-PstI.
