High impact information on Scent Glands

• Dihydroactinidiolide in the supracaudal scent gland secretion of the red fox [1].
• The scent gland tumor of the Syrian hamster is induced by exogenous androgen and estrogen [2].
• FH females also had smaller ovaries and uteri, less developed scent glands, and lower progesterone levels, and were more likely to be anovulatory than PH or SH females, especially in the 11- to 13-week-old age group [3].
• These data suggest that ferrets could use anal scent gland secretions in mate recognition and that seasonal increases in circulating sex steroid hormones increase ferrets' responsiveness to low concentrations of these odors [4].
• Melatonin treatment stimulated accessory sex organs and the scent gland surface area [5].

Anatomical context of Scent Glands

• Previous research has shown that the odor of a variety of organic solvents and of components of the anal scent gland excretions of various predators will elicit a burst of fast waves of about 20 Hz in the olfactory bulb, pyriform cortex, and dentate gyrus of the rat [6].
• In the present paper, adrenomedullin has been localized immunhistochemically in a variety of skin glands of humans, elephants and impalas: apocrine scent glands, eccrine sweat glands, holocrine glands and mammary glands [7].

Associations of Scent Glands with chemical compounds

• Suprasternal scent glands (absent in intact females) and phalluses of females that received T were significantly larger than those of animals that received E or control animals [8].
• The results suggest that scent glands produce graded signals that reflect circulating testosterone titers [9].
• In contrast, all ketones identified were new for opilionid scent glands, although similar ketones are characteristic of scent gland secretions of palpatorid genera Leiobunum and Hadrobunus [10].
• Gas chromatographic-mass spectrometric analyses of the scent gland secretions of Siro duricorius and S. exilis (Opiliones, Cyphophthalmi, Sironidae) revealed a set of 24 components, comprising a series of saturated and unsaturated methyl ketones (C11-C15) and four naphthoquinones [10].
• The aldehyde (E)-2-decenal, a primary component of the stink bug scent gland, was detected in cuticle extracts and found to be selectively fungistatic to certain entomopathogenic fungi, including M. anisopliae [11].

Gene context of Scent Glands

• These data indicate that scent marking induced by AVP injected into the AH-MPOA is similar to environmentally induced scent marking in not requiring the presence of an intact scent gland [12].
