Steroidogenic factor 1 (SF-1) protein and a few related things
The steroidogenic factor 1 (SF-1) protein is a transcription factor involved in sex determination by controlling the activity of genes related to the reproductive glands or gonads and adrenal glands. This protein is encoded by the NR5A1 gene, a member of the nuclear receptor subfamily, located on the long arm of chromosome 9 at position 33.3. It was originally identified as a regulator of genes encoding cytochrome P450 steroid hydroxylases, however, further roles…

Agrin is a large chimeric proteoglycan, a heparan sulfate and chondroitin proteoglycan, whose best-characterised role is in the development of the neuromuscular junction during embryogenesis
Agrin was originally found in the electric organ of Tarpedo california and in the basal lamina at the neuromuscular junction as a protein that directs the aggregation of acetylcholine receptors (AChR) and acetylcholinesterase (AChE) at synaptic sites. Tetronarce californica also known as the Pacific electric ray is a species of electric ray in the family Torpedinidae, endemic to the coastal waters of the northeastern Pacific Ocean from Baja California to British Columbia. It generally inhabits sandy flats, rocky reefs, and kelp forests from the surface…

Sound-induced convulsions in the hamster associated with magnesium deficiency (1947)
Exposure of 16 hamsters maintained on an Mg deficient diet, 10 animals placed on a control diet immediately after a first convulsive attack, 10 Mg-deficient animals given Mg supplements after each induced convulsion, and 12 control animals maintained on adequate purified diet, to sound tests, indicated results similar to those reported for the rat. Spontaneous…

Studies on the nutritional basis of abnormal behavior in albino rats; the effect of pyridoxine deficiency upon sound-induced magnesium tetany (1945)
After a magnesium deficient diet for 5 to 8 days, young rats showed vasodilatation, hyperirritability, and latent tetany. Brief exposures to the sound of a resonated buzzer elicited severe tonic-clonic convulsions. When such a diet was continued for 10 to 23 days, sensitivity increased with death resulting from spontaneous or induced seizures. In a similar…
