FEMALE SEX BIAS AND KINSHIP IN IBERIAN MEGALITHIC SOCIETIES: AN INTERDISCIPLINARY ANALYSIS OF BIOARCHAEOLOGY, aDNA, AND PROTEOMICS

ABSTRACT: Uncertainties of traditional osteological methods in biological sex estimation can now be overcome with genomic and proteomic analyses. The combination of the three methodologies has been used for a better understanding of gender-related funerary rituals of the Iberian megalithic cemetery of Panoría. As a result, 44 individuals have been sexed including, for the first time, non-adults. Contrary to the male bias found in many Iberian and European megalithic monuments, the Panoría population shows a clear sex ratio imbalance in favour of females, with twice as many females as males. Furthermore, this imbalance is found regardless of the criterion considered: sex ratio by tomb, chronological period, method of sex estimation or age group. Biological relatedness and kinship have been explored as cultural explanations for this female-related bias. The results obtained for Panoría are indicative of a female-centred social structure, in which sex and/or gender would have influenced funerary rites and cultural traditions.

Project description:Sex-differences in human liver gene expression were characterized on a genome-wide scale using a large liver sample collection, allowing for detection of small expression differences with high statistical power. 1,249 sex-biased genes were identified, 70% showing higher expression in females. Chromosomal bias was apparent, with female-biased genes enriched on chrX and male-biased genes enriched on chrY and chr19, where 11 male-biased zinc-finger KRAB-repressor domain genes are distributed in six clusters. Top biological functions and diseases significantly enriched in sex-biased genes include transcription, chromatin organization and modification, sexual reproduction, lipid metabolism and cardiovascular disease. Notably, sex-biased genes are enriched at loci associated with polygenic dyslipidemia and coronary artery disease in genome-wide association studies. Moreover, of the 8 sex-biased genes at these loci, 4 have been directly linked to monogenic disorders of lipid metabolism and show an expression profile in females (elevated expression of ABCA1, APOA5 and LDLR; reduced expression of LIPC) that is consistent with the lower female risk of coronary artery disease. Female-biased expression was also observed for CYP7A1, which is activated by drugs used to treat hypercholesterolemia. Several sex-biased drug-metabolizing enzyme genes were identified, including members of the CYP, UGT, GPX and ALDH families. Half of 879 mouse orthologs, including many genes of lipid metabolism and homeostasis, show growth hormone-regulated sex-biased expression in mouse liver, suggesting growth hormone might play a similar regulatory role in human liver. Finally, the evolutionary rate of protein-coding regions for human-mouse orthologs, revealed by dN/dS ratio, is significantly higher for genes showing the same sex-bias in both species than for non-sex-biased genes. These findings establish that human hepatic sex differences are widespread and affect diverse cell metabolic processes, and may help explain sex differences in lipid profiles associated with sex differential risk of coronary artery disease. A first set of randomized liver RNA pools (WS9) was generated by randomly distributing 112 male and 112 female liver RNA samples into 8 pools comprised of 14 male liver samples (pools M1 to M8), and 8 pools of 14 female liver samples each (pools F1 to F8). A second set of 16 pools (WS10) was prepared from the same set of 224 liver samples in the same way (pools M9 to M16 and F9 to F16). The 16 liver RNA pools of each sex were used in a total of 16 male vs. female two-color hybridization microarrays by pairing pool M1 and pool F1, pool M2 with pool F2, etc. Fluorescent labeling of RNA and hybridization of the Alexa 555-labeled and Alexa 647-labeled amplified RNA samples to Agilent Whole Human Genome oligonucleotide microarrays (4 x 44K format; Agilent Technology, Palo Alto, CA; catalog # G4112F) were carried out, with dye swaps to eliminate dye bias.
