Alternative olfactory neuron fates are specified by the LIM homeobox gene lim-4.
The Caenorhabditis elegans AWA, AWB, and AWC olfactory neurons are each required for the recognition of a specific subset of volatile odorants. lim-4 mutants express an AWC reporter gene inappropriately in the AWB olfactory neurons and fail to express an AWB reporter gene. The AWB cells are morphologically transformed toward an AWC fate in lim-4 mutants, adopting cilia and axon morphologies cha...
متن کاملLIM homeodomain transcription factor Isl-1 enhances follicle stimulating hormone-beta and luteinizing hormone-beta gene expression and mediates the activation of leptin on gonadotropin synthesis.
The Lin-11, Isl-1, and Mec-3 (LIM) homeodomain transcription factor Isl-1 has been reported to be involved in pituitary development in the early stages of mouse embryogenesis. Our recent studies have shown that Isl-1 is mainly located in the pituitary gonadotropes throughout pituitary development and persists to adulthood. We still do not know the physiological functions of Isl-1 expression and...
متن کاملLIM-homeodomain transcription factor Isl-1 mediates the effect of leptin on insulin secretion in mice.
In addition to the well known regulating effects of leptin on energy balance and glucose homeostasis through the central nervous system, circulating leptin has a direct effect on pancreatic islet and insulin secretion through its receptor (OBRb). The LIM-homeodomain transcription factor Isl-1 is expressed in all classes of pancreatic endocrine cells and is involved in regulating both islet deve...
متن کاملThe LIM-homeobox gene Islet-1 is required for the development of restricted forebrain cholinergic neurons.
Forebrain cholinergic neurons modulate complex mammalian behaviors such as reward-related learning and cognitive functions. Although their dysfunction is implicated in various psychiatric and neurodegenerative diseases, the factors governing cholinergic neuron differentiation and diversity are mostly unknown. We tested the role of the LIM-homeobox gene Isl1 in the development of forebrain choli...
متن کاملLIM-homeodomain transcription factor Isl-1 mediates kisspeptin's effect on insulin secretion in mice.
Kisspeptin and the G protein-coupled receptor 54 (GPR54) are highly abundant in the pancreas. In addition, circulating kisspeptin directly influences insulin secretion through GPR54. However, the mechanisms by which kisspeptin affects insulin release are unclear. The LIM-homeodomain transcription factor, Isl-1, is expressed in all pancreatic islet cells and is involved in regulating both islet ...
