Zinc is an essential trace element for spermatogenesis.

Zinc (Zn) plays important roles in various biological activities but there is little available information regarding its functions in spermatogenesis. In our current study, we further examined the role of Zn during spermatogenesis in the Japanese eel (Anguilla japonica). Human CG (hCG) was injected into the animals to induce spermatogenesis, after which the concentration of Zn in the testis inc...

Zinc, the Trace Element Essential in Living Organisms

Zinc is a metallic element, of symbol Zn and atomic number 30, that is placed in the group 12 of the periodic table. As an essential trace element, zinc is required to support human biochemical processes. It is found in nearly 200 specific enzymes in the living organisms, and it also serves as structural cofactor for many cellular proteins. [1] Zinc may exert pleiotropic effects in organism; fo...

[Is chromium an essential trace element in human nutrition?].

It has been recognized that chromium is an essential trace element associated with carbohydrate metabolism, and chromium deficiency causes an impaired glucose tolerance. Recently, however, Vincent et al. have reported that chromium is not an essential trace element. In the present report, the author evaluated the nutritional essentiality of chromium by reviewing several previous reports. In alm...

Emi2 Is Essential for Mouse Spermatogenesis.

The meiotic functions of Emi2, an inhibitor of the APC/C complex, have been best characterized in oocytes where it mediates metaphase II arrest as a component of the cytostatic factor. We generated knockout mice to determine the in vivo functions of Emi2-in particular, its functions in the testis, where Emi2 is expressed at high levels. Male and female Emi2 knockout mice are viable but sterile,...

Dynamin 2 is essential for mammalian spermatogenesis

The dynamin family of proteins play important regulatory roles in membrane remodelling and endocytosis, especially within brain and neuronal tissues. In the context of reproduction, dynamin 1 (DNM1) and dynamin 2 (DNM2) have recently been shown to act as key mediators of sperm acrosome formation and function. However, little is known about the roles that these proteins play in the developing te...
