Introduction I NSULIN-like growth factor-I (IGF-I) and its structural homologue, IGF-II, are low
molecular weight peptides that promote cellular mitosis and differentiation in a variety of …

Involvement of insulin-like growth factors (IGFs) and IGF binding proteins (IGFBPs) in
ovarian folliculogenesis has been extensively studied during the last decade. In all …

Given the paucity of information on the potential roles of bone morphogenetic proteins
(BMPs) in the ruminant ovary we conducted immunolocalization and functional studies on …

Hyperinsulinaemic insulin resistance is characteristic of many, if not all, women with poly
cystic ovary syndrome (PCOS). We will review evidence suggesting that hyperinsulinaemia …

Contents The aim of the present paper is to make a comparative study of the expression of
the elements of the insulin‐like growth factor (IGF) system in different mammalian species …

Insulin-like growth factor 1 (IGF-1) is a pleiotropic polypeptide. Its expression is tightly
regulated and it plays significant roles during early development, maturation, and adulthood …

The aim was to investigate potential interactions between FSH and intraovarian growth
factors in modulating secretion of inhibin A (inh A), activin A (act A), follistatin (FS), estradiol …

General characteristics of female reproductive activity, such as seasonality, cyclicity and
triggering of ovulation differ widely among mammals, but common mechanisms underlie …

Insulin-like growth factors (IGFs) are key regulators of development, growth, and longevity. In
most vertebrate species including humans, there is one IGF-1 gene and one IGF-2 gene …

1. Rapidly growing (meat-type) chickens have been intensively selected for over 50 years
and grow up to four times faster than “layer” strains selected for reproductive traits. 2. 2 …
