			* '''Embryo arrest and reactivation: potential candidates controlling embryonic diapause in the tammar wallaby and mink'''{{#pmid:28379301\|PMID28379301}} "Embryonic diapause is a period of developmental arrest which requires coordination of a molecular cross-talk between the endometrium and blastocyst to ensure a successful reactivation, but the exact mechanisms are undefined. The objectives of this study were to screen the tammar blastocyst for potential diapause control factors and to investigate the potential for members of the epidermal growth factor (EGF) family to coordinate reactivation. A select number of factors were also examined in the mink to determine whether their expression patterns were conserved across diapause species. The full-length sequences of the tammar genes of interest were first cloned to establish their level of sequence conservation with other mammals. The uterine expression of EGF family members EGF and heparin-binding EGF (HBEGF) and their receptors (EGFR and erb-b2 receptor tyrosine kinase 4 (ERBB4)) was determined by quantitative reverse-transcriptase polymerase chain reaction (RT-PCR) and immunohistochemistry. Both HBEGF and EGF were significantly upregulated at reactivation compared to diapause. In the blastocyst, the expression of the potential diapause factors Forkhead box class O family members (FOXO1, FOXO3, and FOXO4), tumor protein 53 (TP53), cyclin-dependent kinase inhibitor 1A (CDKN1A), and the EGF family were examined by RT-PCR and immunofluorescence. Nuclear (and hence active) FOXO expression was confirmed for the first time in a mammalian diapause blastocyst in both the tammar and the mink-CDKN1A was also expressed, but TP53 is not involved and EGFR was not detected in the blastocyst. These results indicate that the EGF family, FOXOs, and CDKN1A are promising candidates for the molecular control of embryonic diapause in mammals."

	* '''Desert hedgehog is a mammal-specific gene expressed during testicular and ovarian development in a marsupial'''.{{#pmid:22132805\|PMID22132805}} "These data suggest that there is a highly conserved role for DHH signalling in the differentiation and function of the mammalian testis and that DHH may be necessary for marsupial ovarian development. The receptors PTCH1 and PTCH2 are highly conserved mediators of hedgehog signalling in both the developing and adult marsupial gonads. Together these findings indicate DHH is an essential therian mammal-specific morphogen in gonadal development and gametogenesis."		* '''Desert hedgehog is a mammal-specific gene expressed during testicular and ovarian development in a marsupial'''.{{#pmid:22132805\|PMID22132805}} "These data suggest that there is a highly conserved role for DHH signalling in the differentiation and function of the mammalian testis and that DHH may be necessary for marsupial ovarian development.

	* '''Developmental origins of precocial forelimbs in marsupial neonates'''{{#pmid:21854559\|PMID21854559}} "We present the genome sequence of the tammar wallaby, Macropus eugenii, which is a member of the kangaroo family and the first representative of the iconic hopping mammals that symbolize Australia to be sequenced. The tammar has many unusual biological characteristics, including the longest period of embryonic diapause of any mammal, extremely synchronized seasonal breeding and prolonged and sophisticated lactation within a well-defined pouch. Like other marsupials, it gives birth to highly altricial young, and has a small number of very large chromosomes, making it a valuable model for genomics, reproduction and development. The genome has been sequenced to 2x coverage using Sanger sequencing, enhanced with additional next generation sequencing and the integration of extensive physical and linkage maps to build the genome assembly. We also sequenced the tammar transcriptome across many tissues and developmental time points. Our analyses of these data shed light on mammalian reproduction, development and genome evolution: there is innovation in reproductive and lactational genes, rapid evolution of germ cell genes, and incomplete, locus-specific X inactivation. We also observe novel retrotransposons and a highly rearranged major histocompatibility complex, with many class I genes located outside the complex. Novel microRNAs in the tammar HOX clusters uncover new potential mammalian HOX regulatory elements."
