Ultrastructure and motility of the caudal epididymis spermatozoa from the volcano mouse (Neotomodon alstoni alstoni Merriam, 1898)

open access: yesThe Journal of Experimental Zoology, 2000
The volcano mouse Neotomodon alstoni alstoni is a genus endemic to the higher elevations of the Mexican transvolcanic belt. In the present study we examined for the first time the morphological features of the spermatozoa taken from the caudal epididymis of this species by transmission and scanning electron microscopy. Spermatozoan motility was studied

MALE INFLUENCE ON MATERNAL BEHAVIOR AND OFFSPRING OF CAPTIVE VOLCANO MICE (NEOTOMODON ALSTONI) FROM MEXICO [PDF]

open access: yesJournal of Mammalogy, 2004
Captive male Neotomodon alstoni exhibit paternal care. We tested whether presence of the male in the nest during the postpartum and weaning periods affect maternal care and promoted survival and growth of the offspring. For captive N. alstoni pairs (n = 10) both parents were maintained in the nest until weaning of the young, and in another 10 pairs the

Molecular cloning and functional analysis of the FSH receptor gene promoter from the volcano mouse (Neotomodon alstoni alstoni)

Endocrine, 2009
To gain further insights on the genetic divergence and the species-specific characteristics of the follicle-stimulating hormone receptor (FSHR), we cloned 946 bp of the 5'-flanking region of the FSHR gene from the volcano mouse (Neotomodon alstoni alstoni), and compared its features with those from other mammalian species.

PARENTAL BEHAVIOR OF THE VOLCANO MOUSE,NEOTOMODON ALSTONI(RODENTIA: MURIDAE), IN CAPTIVITY

open access: yesJournal of Mammalogy, 2000
Paternal behavior of the volcano mouse (Neotomodon alstoni) was studied and its role in the care of young compared with that of the female. Paternal behavior of this rodent under laboratory conditions consisted of direct and indirect activities, such as ...

cDNA sequence, 5′-flanking region, and promoter activity of the Neotomodon alstoni alstoni Clara cell secretory protein gene

Archives of Biochemistry and Biophysics, 2004
To better understand the phylogenetic divergence and the species-specific characteristics of the Clara cell secretory protein (CCSP), we cloned the cDNA encoding the neotomodon CCSP (nCCSP) and analyzed its tissue-specific expression. The full-length cDNA is 451bp long and predicts an amino acid sequence of 93 residues.

Hypothalamic expression of anorexigenic and orexigenic hormone receptors in obese femalesNeotomodon alstoni:Effect of fasting

Nutritional Neuroscience, 2013
Obesity is a world problem that requires a better understanding of its physiological and genetic basis, as well as the mechanisms by which the hypothalamus controls feeding behavior. The volcano mouse Neotomodon alstoni develops obesity in captivity when fed with regular chow diet, providing a novel model for the study of obesity.
