Using the modified stem-loop RT-PCR method described above, we further endeavored to determine the timing of expression patterns of miRNA sja-let-7, sja-miR-71 and sja-bantam across the life span of S. japonicum.
A transcriptional STOP cassette flanked by two loxP sites was inserted between the promoter and coding region, ensuring that the timing and expression pattern of this transgene was dependent on the Cre-transgenic animals they were to be crossed to.
While I believe the result will be the expected one (especially in light of the nanostring data) formally, based on this panel alone and the description of the procedure, the difference in timing and expression pattern could arise from relatively more efficient ntl detection.
Because the timing and expression pattern of Smc6 in differentiating spermatogonia appears similar to the gradual development of heterochromatin during spermatogenesis, we performed co-immunofluorescence microscopy on testis sections using antibodies against Smc6, the heterochromatin marker H3K9me3 and DAPI as DNA-stain to determine specific cell types by nuclear morphology and tubular context.
We next looked at the overall features and timing of the expression patterns of the periodically expressed genes.
We wished to further examine the exact timing of when these gene expression patterns arise.
The ssn8 mutants maintain the responsiveness to mating inducing signals, but the intensity and timing of gene expression pattern are changed.
The expression patterns and timings of peak expression differed among FCGRs.
However, if we are to develop novel chronotherapeutic approaches, then a deeper understanding of clock physiology (from cellular clock communication to mechanisms of molecular timing and organ-specific clock gene expression patterns) will be required.
Many highly conserved miRNAs that exhibit particular expression patterns with specific timing and tissue specificity, have critical functions in growth, development, differentiation, apoptosis, metabolism and biotic and abiotic stress responses, regulating specific target mRNAs.
