WormMine: Gene WBGene00019832

• WormBase Gene ID: WBGene00019832
• Gene Name: osg-1
• Sequence Name: R02F2.2
• Brief Description: R02F2.2 encodes a guanine nucleotide exchange factor of the Dbl family; R02F2.2 plays a role in aging, and appears to be recruited, under conditions of oxidative stress, to effect loss of neuronal function via dysregulation of RHO-1 GTPase-mediated signaling and subsequent effects on the actin cytoskeleton and actin dynamics; an R02F2.2::GFP reporter fusion is expressed in body wall muscles, head muscles, and in several neurons in the head, including the ASE and FLP neurons.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable guanyl-nucleotide exchange factor activity. Involved in response to oxidative stress. Expressed in body wall musculature and head neurons. Is an ortholog of human ARHGEF17 (Rho guanine nucleotide exchange factor 17).
• Biotype: SO:0001217

All available microarray datasets for the GPL200 platform (Affymetrix C. elegans Genome Array) were obtained from the GEO repository. This included 2243 individual microarray experiments. These were normalized against each other with the software RMAexpress (Bolstad, 2014). Based on these normalized values, Pearsons correlation coefficients were obtained for each probe-probe pair of the 22,620 probes represented on this array type. The resulting list of correlation coefficients was then ranked to generate the ranked coexpression database with information on each probe represented on the GPL200 platform.

	Maternal class (M): genes that are called present in at least one of the three PC6 replicates.	A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression. P-values were not corrected for multiple testing.	[cgc5767]:expression_class_M

	Strictly maternal class (SM): genes that are the subset of maternal genes that are not also classified as embryonic.	A modified Welch F statistic was used for ANOVA. For each gene, regressed error estimates were substituted for observed error estimates. The substitution is justified by the lack of consistency among the most and least variable genes at each time point. Regressed error estimates were abundance-dependent pooled error estimates that represented a median error estimate from a window of genes of similar abundance to the gene of interest. A randomization test was used to compute the probability Pg of the observed F statistic for gene g under the null hypothesis that developmental time had no effect on expression.

	Genes that showed oscillating mRNA expression level throughout the 16 hour time courses from L3 larva to young adult.	The following three lines of R code were used to perform the classification: increasing <-2*amplitude-PC1 < -1.7; oscillating <-!increasing & (amplitude > 0.55); flat <-!increasing & !oscillating; Note that the amplitude of a sinusoidal wave corresponds to only half the fold change between trough and peak.

	Transcripts that showed significantly increased expression in hda-1[KKRR]-smo-1 in gonads dissected from 1-day old adult animals.	Salmon was used to map the mRNA-seq reads with the worm database WS268, and its output files were imported to DESeq2 in R. The differentially expressed genes were filtered by fold change more than 2 and adjusted p-value < 0.05. The scatter plots were generated by the plot function in R.
