Comparison of L3 http://www.tongji.org/members/jeffsalmon70/activity/233306/ molting worms with L4 post-molting worms revealed 1104 genes that had been up regulated in the course of molting. Of those genes, a set of 434 genes was up regulated in both the L3 and L4 molt. The exact same comparison revealed that 1900 genes have been down regulated throughout L3 molting compared with L4 wake and that 1380 genes were down regulated through L4 molting compared with young adult post-molting. Of these genes, a set of 191 genes was down regulated in each the L3 and L4 molt four Gene Expression during Lethargus . We reasoned that gene expression modifications that could be biologically relevant would oscillate with substantial amplitude in phase with the molting cycle. We applied an arbitrary threshold and selected only those genes that oscillated with an amplitude of at the very least 50%. We obtained a core set of genes that oscillated together with the molting cycle of 342 genes that had been up regulated through molting and 178 genes that were down-regulated through molting. For some of the genes, alterations in expression levels had been quite massive: 139 genes that had been up regulated throughout molting and 17 genes that had been down regulated through molting showed a much more than ten fold alter in expression. Therefore, our transcriptional profiling revealed 342 oscillating core genes which can be up regulated during molting and 178 oscillating core genes that happen to be down regulated in the course of molting. Validation of information by comparison to known oscillating genes and by qPCR Recent perform applied RNA sequencing to show that there's extensive oscillatory gene expression during C. elegans larval development. We wanted to validate our data set and see how many of your genes that we have identified have been reported to be oscillating. We located that in the 178 core genes that were down regulated during molting 128 were shown to become oscillating GO term1 Up regulated structural constituent of cuticle structural molecule activity extracellular region serine-type endopeptidase inhibitor activity response to stress membrane metallopeptidase activity chitin metabolic approach defense response amine transport peroxidase activity Down regulated catalytic activity metabolic method transferase activity lipid metabolic procedure L-serine metabolic course of action cation binding carboxylic acid biosynthetic procedure monooxygenase activity integral to membrane icosanoid metabolic procedure cysteine synthase activity ecdysis, collagen and cuticulin-based cuticle cellular ketone metabolic process 1 based on the literature. From the 342 core genes that were up regulated during molting 254 have been shown to become oscillating . We then looked at the phase on the oscillation of your expression in the genes that have been both previously shown to become oscillating and that we also identified to be enriched throughout molting. The phase is defined by dividing the length from the full period, roughly eight hours, by 360u. This results in 45u corresponding to 1 hour. The phase for every gene is determined by fitting a cosine function using a fixed period of eight hours. Virtually all genes that we identified to become enriched for the duration of molting had a phase of about 170u290u, and all genes that have been enriched throughout post-molting were outdoors of this phase variety. This indicates that we have been able to recognize oscillating genes which have the peak oscillation.
