Abstract: Male infertility is a long-standing enigma of significant medical concern. The integrity of sperm chromatin is a clinical indicator of male fertility and in vitro fertilization potential: chromosome aneuploidy and DNA decondensation or damage are correlated with reproductive failure. Identifying conserved proteins important for sperm chromatin structure and packaging can reveal universal causes of infertility. Here we combine proteomics, cytology and functional analysis in Caenorhabditis elegans to identify spermatogenic chromatin-associated proteins that are important for fertility. Our strategy employed multiple steps: purification of chromatin from comparable meiotic cell types, namely those undergoing spermatogenesis or oogenesis; proteomic analysis by multidimensional protein identification technology (MudPIT) of factors that co-purify with chromatin; prioritization of sperm proteins based on abundance; and subtraction of common proteins to eliminate general chromatin and meiotic factors. Our approach reduced 1,099 proteins co-purified with spermatogenic chromatin, currently the most extensive catalogue, to 132 proteins for functional analysis. Reduction of gene function through RNA interference coupled with protein localization studies revealed conserved spermatogenesis-specific proteins vital for DNA compaction, chromosome segregation, and fertility. Unexpected roles in spermatogenesis were also detected for factors involved in other processes. Our strategy to find fertility factors conserved from C. elegans to mammals achieved its goal: of mouse gene knockouts corresponding to nematode proteins, 37% (7/19) cause male sterility. Our list therefore provides significant opportunity to identify causes of male infertility and targets for male contraceptives..

Abstract: This study aimed to compare the symptoms, unmet needs, and QoL reported by women at 6 months to <2 years and 2 to 5 years following surgery and adjuvant treatment for breast cancer. It also evaluated the relationships among symptoms, unmet needs, and QoL using structural equation modeling. In this study, 113 and 137 survivors following breast cancer treatment 6 months to <2 years and 2 to 5 years, respectively, completed the Memorial Symptom Assessment Scale, the Supportive Care Needs Survey-34, and the Medical Outcomes Study 12-item Short Form Health Survey version 2.0 during their medical follow-up. The mean numbers of symptoms and unmet needs were 5.43 and 3.0, respectively, for survivors at <2 years, and 5.24 and 2.42, respectively, for survivors at 2 to 5 years following treatment. The most common reported symptoms were related primarily to physical domains. No significant differences were found between the two survivor groups on the MSAS scores. Survivors at <2 years reported significantly higher scores in Psychological and Health Care System/Information needs (p < 0.01), and lower composite scores in physical and mental QoL (p < 0.05) than those at 2 to 5 years post-treatment. Significant direct and indirect effects were found of symptom burden through unmet needs on survivors' physical and mental QoL after adjustment for survival time, and the models showed a good fit. Results suggest that breast cancer survivors continue to endure many symptoms independent of the survivorship period. The unmet needs mediate the relationship between symptom burden and survivors' QoL..

Abstract: Somatic cell nuclear transfer allows trans-acting factors present in the mammalian oocyte to reprogram somatic cell nuclei to an undifferentiated state. We show that four factors (OCT4, SOX2, NANOG, and LIN28) are sufficient to reprogram human somatic cells to pluripotent stem cells that exhibit the essential characteristics of embryonic stem (ES) cells. These induced pluripotent human stem cells have normal karyotypes, express telomerase activity, express cell surface markers and genes that characterize human ES cells, and maintain the developmental potential to differentiate into advanced derivatives of all three primary germ layers. Such induced pluripotent human cell lines should be useful in the production of new disease models and in drug development, as well as for applications in transplantation medicine, once technical limitations (for example, mutation through viral integration) are eliminated..
