WormBase Gene ID  ? WBGene00001434 Gene Name  fkh-2
Sequence Name  ? T14G12.4 Brief Description  fkh-2 encodes one of 15 C. elegans forkhead transcription factors and is homologous to Drosophila sloppy-paired (slp) and the vertebrate Brain Factor 1 (BF-1, OMIM:164874, expression is restricted to the central nervous system); fkh-2 is required, along with ceh-37, for proper development of the AWB chemosensory neurons; specifically, fkh-2 is required for development of AWB-specific ciliary and dendritic structures and for positive regulation of expression of genes such as str-1, odr-1, and kap-1; in addition, although loss of fkh-2 activity via RNA-mediated interference (RNAi) results in only mild locomotion defects in L1 larvae, loss of both fkh-2 and pes-1, which also encodes a forkhead transcription factor, results in embryonic and larval lethality; fkh-2 is expressed broadly in embryos in descendants of the D and AB founder cell lineages; postembryonically, FKH-2 is expressed in AWB, and other, chemosensory neurons; fkh-2 expression in AWB is positively regulated by the DAF-19 RFX transcription factor.
Organism  Caenorhabditis elegans Automated Description  Enables DNA-binding transcription factor activity. Involved in several processes, including neuron differentiation; non-motile cilium assembly; and positive regulation of transcription by RNA polymerase II. Located in nucleus. Expressed in several structures, including AWB; Daaa; body wall muscle cell from D lineage; head muscle; and somatic nervous system. Is an ortholog of human FOXG1 (forkhead box G1).

  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

WBPaper00031003:hlh_1_enriched
  Embryonic class (E): genes that significantly increase in abundance at some point during embryogenesis. 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.

The P-values were adjusted for multiple testing with a false-discovery rate (50). Probe sets with fold-change > 1.5 and q-value < 0.05 were used as a cut-off for C. elegans microarrays WBPaper00042561:smgl-1(RNAi)_downregulated
  Genes that showed decreased expression after 1-methylnicotinamide (MNA) treatment. Raw counts for the genes were analyzed using the R Statistical Computing Environment and the Bioconductor packages DESeq and edgeR. Both packages provide statistical routines for determining differential expression in digital gene expression data using a model based on the negative binomial distribution. The resulting p-values were adjusted using the Benjamini and Hochberg's approach for controlling the false discovery rate (FDR). If both FDR values (by DESeq and edgeR) were smaller than p = 0.05, genes were assigned as differentially expressed. WBPaper00044260:1-methylnicotinamide_downregulated
  Genes that showed decreased expression after nicotic acid (NA) treatment. Raw counts for the genes were analyzed using the R Statistical Computing Environment and the Bioconductor packages DESeq and edgeR. Both packages provide statistical routines for determining differential expression in digital gene expression data using a model based on the negative binomial distribution. The resulting p-values were adjusted using the Benjamini and Hochberg's approach for controlling the false discovery rate (FDR).
