"we used immunofluorescence (IF) assays to detect MSP and GSP-3 proteins and fluorescence in situ hybridization (FISH) to detect msp transcripts. Interestingly, IF of MSP and GSP-3, two positively regulated targets, suggested that these proteins were only slightly reduced in
alg-3/4 germlines during spermatogenesis and in haploid spermatids at 20C compared to WT (Figure 3A). At 25C, however, MSP and GSP-3 were severely reduced throughout the spermatogenic germline of
alg-3/4 males compared toWTand failed to accumulate in spermatids (Figure 3A). Although GSP-3 protein was depleted overall, we found that it also accumulated abnormally in the nuclei of
alg-3/4 mutants, particularly at 25C (Figure 3A)."
