    ..Our results suggest that C. elegans spermatogenesis requires either this specific isoform of eIF4E or an elevated level of eIF4E. ..

    ..Our findings demonstrate that both PGL-2 and PGL-3 are components of P granules, both interact with PGL-1, and at least PGL-3 functions redundantly with PGL-1 to ensure fertility in both sexes of C. elegans...

    ..We propose that self-association of scaffold proteins that can bind to RNPs is a general mechanism by which large RNP granules are formed. ..

    ..Our findings also support the view that P granules facilitate mRNA silencing by providing an environment in which translational repressors can encounter their mRNA targets immediately upon exit from the nucleus. ..
  5. Kawasaki I, Shim Y, Kirchner J, Kaminker J, Wood W, Strome S. PGL-1, a predicted RNA-binding component of germ granules, is essential for fertility in C. elegans. Cell. 1998;94:635-45 pubmed
    ..Elimination of PGL-1 results in defective germ granules and sterility. Interestingly, PGL-1 function is required for fertility only at elevated temperatures, suggesting that germline development is inherently sensitive to temperature. ..

    ..Our results suggest that P granules extend the NPC environment in the germ line and provide insights into the roles of the PGL and GLH family proteins. ..

    ..The loss of yeast Rec8p from chromosome arms at meiosis I and centromeres at meiosis II coordinates the disjunction of homologs and sister chromatids at the two meiotic divisions. ..

    ..These results indicate that the acquisition of germline characteristics by the somatic cells of C. elegans mutants with increased longevity contributes to their increased health and survival. ..
