Asymmetry of spermiation and sperm surface charge patterns over the giant acrosome in the musk shrew Suncus murinus
Spermatozoa of the shrew Suncus murinus, a mammal with abdominal testes, exhibit four unusual features: a giant acrosome; a dorsoventral asymmetry of their spermiation; a dorsoventral asymmetry of their head surface character; and also apparent surface maturity as they enter the epididymis. A Sertoli cell-periacrosomal cisternal complex envelops the giant acrosome during spermatid maturation. S...

متن کاملSequence variation and evolution of the mitochondrial DNA control region in the musk shrew, Suncus murinus.
The complete mitochondrial DNA (mtDNA) control region was cloned and sequenced in the musk shrew, Suncus murinus, Insectivora. The general aspect was similar to that found in other mammals. We have found in two locations of this region the presence of arrays of tandem repeats like those in other shrew species. One array was located in the left domain containing the termination-associated sequen...
متن کاملExpression and localization of aquaporins in the kidney of the musk shrew (Suncus murinus).
Expression and localization of members of the aquaporin (AQP) family (AQP1, 2, 3, 4, and 5) in the kidney of the musk shrew (Suncus murinus) was examined by immunohistochemistry. AQP1 was expressed in the proximal tubules and in the thin limb of the loops of Henle. AQP1 was the only water channel expressed in the proximal nephron examined, indicating that AQP1 may be an independent water transp...
متن کاملConditioned Flavor Preference and the US Postexposure Effect in the House Musk Shrew (Suncus Murinus)
The house musk shrew (Suncus murinus) is the only species of mammalian insectivore that can be domesticated and used as a laboratory animal, and is an interesting subject in terms of evolutionary and comparative aspects. The present study on the learning faculties of shrews examines the possibility of acquiring a conditioned flavor preference and the effects of US postexposure. Subjects were al...
