Abstract
One of the most compelling features of dry eye disease (DED) is that it occurs more frequently in women than men. In fact, the female sex is a significant risk factor for the development of DED. This sex-related difference in DED prevalence is attributed in large part to the effects of sex steroids (e.g. androgens, estrogens), hypothalamic-pituitary hormones, glucocorticoids, insulin, insulin-like growth factor 1 and thyroid hormones, as well as to the sex chromosome complement, sex-specific autosomal factors and epigenetics (e.g. microRNAs). In addition to sex, gender also appears to be a risk factor for DED. "Gender" and "sex" are words that are often used interchangeably, but they have distinct meanings. "Gender" refers to a person's self-representation as a man or woman, whereas "sex" distinguishes males and females based on their biological characteristics. Both gender and sex affect DED risk, presentation of the disease, immune responses, pain, care-seeking behaviors, service utilization, and myriad other facets of eye health. Overall, sex, gender and hormones play a major role in the regulation of ocular surface and adnexal tissues, and in the difference in DED prevalence between women and men. The purpose of this Subcommittee report is to review and critique the nature of this role, as well as to recommend areas for future research to advance our understanding of the interrelationships between sex, gender, hormones and DED.

Abstract
Tissue and organ development is a time of exquisite sensitivity to environmental exposures, which can reprogram developing tissues to increase susceptibility to adult diseases, including cancer. In the developing prostate, even brief exposure to endocrine-disrupting chemicals (EDCs) can increase risk for developing cancer in adulthood, with disruption of the epigenome thought to play a key role in this developmental reprogramming. We find that EDC-induced nongenomic phosphoinositide 3-kinase; (PI3K) signaling engages the histone methyltransferase mixed-lineage leukemia 1 (MLL1), responsible for the histone H3 lysine 4 trimethylation (H3K4me3) active epigenetic mark, to increase cleavage and formation of active MLL1 dimers. In the developing prostate, EDC-induced MLL1 activation increased H3K4me3 at genes associated with prostate cancer, with increased H3K4me3 and elevated basal and hormone-induced expression of reprogrammed genes persisting into adulthood. These data identify a mechanism for MLL1 activation that is vulnerable to disruption by environmental exposures, and link MLL1 activation by EDCs to developmental reprogramming of genes involved in prostate cancer.
