Regulation of Growth by Negative Growth Regulators
1989The concept of growth regulation by endogenous inhibitors was first suggested by studies on wound healing and carcinogenesis (see Wang and Hsu, 1986). This area of research has long suffered from the fact that purification of specific compounds that inhibited cell proliferation (or differentiation) of normal cells proved elusive.

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.

Talanta: The International Journal of Pure and Applied Analytical Chemistry, 2019
Four types of ionic liquids which composed of cation with imidazole ring and anion with benzene, naphthalene, anthraquinone and naphthoquinone ring were prepared and named VOIm+BenSO3-, VOIm+NapSO3-, VOIm+AQSO3- and VOIm+NQSO3-, respectively. Then, ionic

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.

Plant growth regulators for enhancing revegetation success in reclamation: A review
Ecological Engineering: The Journal of Ecotechnology, 2018Plant growth regulators (PGRs) are natural hormones and synthetic hormone analogues. Types of PGRs reviewed in this paper include auxins, gibberellins, cytokinins, ethylene, abscisic acid, brassinosteroids and jasmonates. At low concentrations, PGRs have

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 ...

While multiple hormones influence somatic growth, the main regulator of postnatal growth is growth hormone. Growth hormone (GH) is secreted in a pulsatile manner from the anterior pituitary primarily as a 22-kilodalton molecule (although other forms may be found).

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 ...
