Review
Dosage compensation and the global re-balancing of aneuploid genomes Matthias Prestel, Christian Feller, Peter B Becker Genome Biology 2010, 11:216 (26 August 2010) The dosage-compensation systems that equalize X-chromosome expression between sexes exemplify the intricacies of compensating for differences in gene copy number.

Review
Escape from X inactivation in mice and humans Joel B Berletch, Fan Yang, Christine M Disteche Genome Biology 2010, 11:213 (24 June 2010) Species-specific differences in X-linked genes that escape inactivation suggest a role in the evolution of sex differences.

Regional differences in dosage compensation on the chicken Z chromosome Esther Melamed, Arthur P Arnold Genome Biology 2007, 8:R202 (27 September 2007) Microarray data analysis revealed a cluster of well compensated genes in the MHM (male-hypermethylated) region on chicken chromosome Zp, whereas Zq is enriched in non-compensated genes. The non-coding MHM RNA may therefore play a role in dosage compensation in the female. |

Faced with inequality: chicken do not have a general dosage compensation of sex-linked genes Hans Ellegren, Lina Hultin-Rosenberg, Björn Brunström, Lennart Dencker, Kim Kultima, Birger Scholz BMC Biology 2007, 5:40 (20 September 2007) In a surprising contrast to mammals and flies, in which dosage compensation equalizes gene expression between sex chromosomes, chicken embryos lack global dosage compensation and have large-scale imbalances of sex-linked gene expression between the sexes.

Dosage compensation is less effective in birds than in mammals Yuichiro Itoh, Esther Melamed, Xia Yang, Kathy Kampf, Susanna Wang, Nadir Yehya, Atila Van Nas, Kirstin Replogle, Mark R Band, David F Clayton, Eric E Schadt, Aldons J Lusis, Arthur P Arnold Journal of Biology 2007, 6:2 (22 March 2007) Male:female ratios of gene expression in zebra finch and chicken reveal that birds, unlike mammals, have surprisingly ineffective sex-chromosome dosage compensation mechanisms resulting in an imbalance between autosomal and sex-linked genes.
