The evolution of imprinting: chromosomal mapping of orthologues of mammalian imprinted domains in monotreme and marsupial mammals. [PDF]
, 2011 BACKGROUND: The evolution of genomic imprinting, the parental-origin specific expression of genes, is the subject of much debate. There are several theories to account for how the mechanism evolved including the hypothesis that it was driven by the ...

Can we study whisker movements to gain insights into the natural sensory behaviours of mammals?
The Journal of Physiology, Volume 603, Issue 22, Page 6733-6745, November 15, 2025.Abstract figure legend The recommended future of whisker science research is integrating findings from the laboratory with studies from other captive institutions (such as zoos, rehabilitation centres and specialist research institutes) and field observations.

Reproductive Biology and Endocrinology, 2003 Female opossums are induced into estrus by direct exposure to a non-volatile pheromone in male scentmarks. Juvenile females develop this responsiveness by 150 days of age (days), and earlier (130 days) if exposed to male pheromone beginning at 90 days ...

Molecular Ecology, Volume 34, Issue 20, October 2025.ABSTRACT The molecular basis of sex determination (SD), while being extensively studied in model organisms, remains poorly understood in many animal groups. Bivalves, a diverse class of molluscs with a variety of reproductive modes, represent an ideal yet challenging clade for investigating SD and the evolution of sexual systems.

Retrotransposon silencing by DNA methylation can drive mammalian genomic imprinting [PDF]
, 2015 Among mammals, only eutherians and marsupials are viviparous and have genomic imprinting that leads to parent-of-origin-specific differential gene expression. We used comparative analysis to investigate the origin of genomic imprinting in mammals. PEG10 (

Serum Proteinogram in the Free‐Living Brazilian Common Opossum (Didelphis aurita)
ELECTROPHORESIS, Volume 46, Issue 18, Page 1447-1454, September 2025.ABSTRACT Didelphis aurita is a synanthropic marsupial widely distributed in southeastern Brazil, known for its resistance to venom and its relevance in biomedical research. This study aimed to characterize the serum proteinogram of free‐living D. aurita individuals.

American marsupials chromosomes: why study them?
Genetics and Molecular Biology, 2009 Marsupials, one of the three main groups of mammals, are only found in Australia and in the American continent. Studies performed in Australian marsupials have demonstrated the great potential provided by the group for the understanding of basic genetic ...

Age-dependent changes in the proteome following complete spinal cord transection in a postnatal South American opossum (Monodelphis domestica). [PDF]
PLoS ONE, 2011 Recovery from severe spinal injury in adults is limited, compared to immature animals who demonstrate some capacity for repair. Using laboratory opossums (Monodelphis domestica), the aim was to compare proteomic responses to injury at two ages: one when ...
