Current Opinion in Genetics & Development, 1992
The proliferation of cells is regulated by countervailing positively- and negatively-acting signaling networks. The anti-proliferative signals, the study of which has been much neglected until recently, are often conveyed by growth-inhibitory peptides.

Growth hormone regulation of follicular growth
Reproduction, Fertility and Development, 2012The somatotropic axis – consisting of growth hormone (GH), the insulin-like growth factors 1 and 2 (IGF1 and IGF2), GH binding protein (GHBP), IGF binding proteins (IGFBPs) 1 to 6, and the cell-surface receptors for GH and the IGFs – has major effects on growth, lactation and reproduction.

Abstract While multiple hormones influence somatic growth, the main regulator of postnatal growth is growth hormone (GH). Growth hormone is secreted in a pulsatile manner from the anterior pituitary primarily as a 22 kD molecule (although other forms may be found). The development of the pituitary gland, as well as GH gene expression, is

AbstractThis chapter examines plant growth regulators used for blueberries (Vaccinium spp.) in regard to their application and the factors that affect their performance. Current and potential uses of these substances (control vegetative growth, enhancement of leaf development, delay flowering, inhibition of flower bud formation or elimination of ...

Neuropeptides as growth regulators
British Medical Bulletin, 1989The classical role of neuropeptides as fast-acting neurohumoral signallers has recently been challenged by the discovery that many neuropeptides are also growth factors stimulating slow-acting mitogenesis. Their mechanisms of action have been studied in cell culture, and their cell-surface receptors have been characterized pharmacologically using ...

Growth Factors and Regulation of Cell Growth
Annual Review of Medicine, 1982A new class of polypeptide hormones known collectively as growth factors has been identified. These polypeptides are able to stimulate DNA synthesis and mitosis of cells cultured in vitro. Growth factors have been isolated from several sources, including platelets, submaxillary glands, pituitary, brain, and medium conditioned by cells grown in vitro ...

Physiological Reviews, 1986
The liver is a conditional renewal system, which in the adult organism undergoes minimal cell production and/or cell renewal. However, a reduction in liver cell mass, because of either actual cell loss or cell atrophy, evokes a rapid regenerative response tailored to replace the lost tissue.

Transforming Growth Factor Regulation of Keratinocyte Growth
1993Transforming growth factors (TGF) were originally defined by their ability to induce morphologic transformation in monolayer culture and stimulate soft agar growth of rodent fibroblast cell lines (DeLarco and Todaro 1978; Moses et al. 1981; Roberts et al. 1981). Early studies with TGF indicated that they may play a role in neoplastic transformation and
