Description
It has generally been assumed that most differences between males and females are due to developmental and hormonal differences between the sexes. Here we investigate the contribution of sex chromosomal complement to such sexual dimorphisms. These genome-wide transcription profiling showed that the expression of hundreds of autosomal genes was sensitive to sex chromosome complement, rather than gender. The existence of such differences between males and females holds important implications for understanding sexual dimorphisms in physiology and disease hitherto attributed solely to gender or hormonal effects.

Description
In order to elucidate the molecular mechanism giving rise to the rare In(Lu) type of Lu(a-b-) blood group phenotype we compared the transcriptome of normal and In(Lu) erythroblasts at different stages of maturation. Many erythroid-specific genes had reduced transcript levels suggesting the phenotype resulted from a transcription factor abnormality. A search for mutations in erythroid transcription factors revealed mutations in the promoter or coding sequence of EKLF in 21 of 24 individuals with the In(Lu) phenotype. In all cases the mutant EKLF allele occurred in the presence of a normal EKLF allele. Individuals with the In(Lu) phenotype have no reported pathology indicating that one functional EKLF allele is sufficient to sustain human erythropoiesis. These data provide the first description of inactivating mutations in human EKLF and the first demonstration of a blood group phenotype resulting from mutations in a transcription factor.

Description
Transient mitochondrial stress can promote beneficial physiological responses and longevity, termed "mitohormesis." To interrogate mitohormetic pathways in mammals, we generated mice in which mitochondrial superoxide dismutase 2 (SOD2) can be knocked-down in an inducible and reversible manner (iSOD2-KD). Depleting SOD2 only during embryonic development did not cause post-natal lethality, allowing us to probe adaptive responses to mitochondrial oxidant stress in adult mice. Liver from adapted mice had increased mitochondrial biogenesis and antioxidant gene expression and fewer reactive oxygen species. Gene expression analysis implicated non- canonical activation of the Nrf2 antioxidant and PPAR-PGC-1 mitochondrial signaling pathways in this response. Transient SOD2 knock-down in embryonic fibroblasts from iSOD2-KD mice also resulted in adaptive mitochondrial changes, enhanced antioxidant capacity, and resistance to a subsequent oxidant challenge. We propose that mitohormesis in response to mitochondrial oxidative stress in mice involves sustained basal activation of mitochondrial and antioxidant signaling pathways to establish a heightened antioxidant state.
