WormBase Gene ID  ? WBGene00000517 Gene Name  cki-2
Sequence Name  ? T05A6.2 Brief Description  cki-2 encodes a cyclin-dependent kinase (CDK) inhibitor of the CIP/KIP family, orthologous to human CDKN1C (OMIM:600856, which when mutated leads to Beckwith-Wiedemann syndrome) that may play a role in cell cycle progression during embryogenesis; CKI-2 interacts with PCN-1, a proliferating cell nuclear antigen homolog, SMO-1, a SUMO (ubiquitin related) homolog, and the RING domain-containing protein C06A5.9.
Organism  Caenorhabditis elegans Automated Description  Predicted to enable cyclin-dependent protein serine/threonine kinase inhibitor activity. Involved in gonad development; regulation of cell cycle process; and regulation of cell division. Predicted to be located in nucleus. Expressed in several structures, including P3.pa; P3.pp; P5.ppp; P7.paa; and germ line. Human ortholog(s) of this gene implicated in several diseases, including carcinoma (multiple); hematologic cancer (multiple); and urinary system cancer (multiple). Is an ortholog of human CDKN1B (cyclin dependent kinase inhibitor 1B).

  Transcripts of coding genes that showed significantly decreased expression in muscle. DESeq2 (version 1.24.0). Transcripts with a false-discovery rate adjusted p-value less than 0.05 were considered significantly differentially expressed. WBPaper00062325:muscle_depleted_coding-RNA
  Transcripts expressed in neuronal cells, by analyzingfluorescence-activated cell sorted (FACS) neurons. DESeq. False discovry rate (FDR) < 0.1. WBPaper00048988:neuron_expressed

  mRNAs that showed decreased expression in 1 cell mebryo comparing to in oocyte, according to RNAseq analysis. Gaussian error propagation. As cutoff for the up-regulated genes authors used log2 fold change > 1 and P < 0.05 and as cutoff for the down-regulated genes authors used log2 fold change < -1 and P < 0.05. WBPaper00045420:fertilization_downregulated_transcript
Osmotic stress Transcripts that showed significantly altered expression with 500 mM salt (NaCl) vs 100 mM salt when food was present DESeq(version 1.10.1), FDR < 0.05. WBPaper00050726:OsmoticStress_regulated_Food
Osmotic stress Transcripts that showed significantly altered expression with 500 mM salt (NaCl) vs 100 mM salt when no food was present DESeq(version 1.10.1), FDR < 0.05. WBPaper00050726:OsmoticStress_regulated_NoFood
  Transcripts that showed significantly higher expression in somatic gonad precursor cells (SGP) vs. head mesodermal cells (hmc). DESeq2, fold change >= 2, FDR <= 0.01. WBPaper00056826:SGP_biased
  Transcripts expressed in hypodermis, according to PAT-Seq analysis using Pdpy-7-GFP-3XFLAG mRNA tagging. Cufflinks FPKM value >=1. WBPaper00050990:hypodermis_expressed
  Transcripts expressed in intestine, according to PAT-Seq analysis using Pges-1-GFP-3XFLAG mRNA tagging. Cufflinks FPKM value >=1. WBPaper00050990:intestine_expressed
  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. P-values were not corrected for multiple testing. [cgc5767]:expression_class_SM

  Genes with increased RNA expression after 24 hours rotenone treatment EdgeR provides 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 Hochbergs approach for controlling the false discovery rate (FDR). Transcripts with an adjusted p-value smaller 0.05 were assigned as differentially expressed. WBPaper00044426:rotenone_24h_upregulated
  Genes that showed expression levels higher than the corresponding reference sample (L2 all cell reference). A Mann-Whitney U test with an empirical background model and FDR correction for multiple testing was used to detect expressed transcripts (Benjamini and Hochberg 1995). Genes and TARs with an FDR <= 0.05 were reported as expressed above background. Authors detected differentially expressed transcripts using a method based on linear models. Genes and TARs were called differentially expressed if the FDR was <= 0.05 and the fold change (FC) >= 2.0. To more strictly correct for potential false-positives resulting from multiple sample comparisons, authors divided individual FDR estimates by the number of samplesor sample comparisons, respectively. This resulted in an adjusted FDR of 1.3 * 0.0001 for expression above background and of 7.4 * 0.0001 for differential expression. Authors called genes selectively enriched in a given tissue if they met the following requirements: (1) enriched expression in a given tissue (FDR <= 0.05 and FC >= 2.0), (2) fold change versus reference among the upper 40% of the positive FC range observed for this gene across all tissues, and (3) fold-change entropy among the lower 40% of the distribution observed for all genes.

Temprature shift to 28C for 24 hours. Transcripts that showed significantly decreased expression after animals were exposed to 28C temperature for 24 hours. Differentially expressed genes wereidentified using DESeq (v.1.18.0) by normalizing readsbased on the negative binomial distribution method andcomparing each HS timepoint to the 0-h control.

Picture: Fig 3.   Expr8659 As previously reported, GFP is widely observed during embryogenesis. Similarly, GFP is also generally expressed during larval development, being observed within both dividing and terminally differentiated cells. For example, cells within the seam and intestinal lineages strongly express the Pcki-2::gfp reporter. The VPCs and their descendent cells also express GFP.  
    Expr9639 By semiquantitative RT-PCR and immunofluorescent detection, it was found that of the two Cip/Kip proteins, CKI-2 is the predominant CKI in the adult germline. Immunodetection studies revealed that CKI-2 protein was absent from germline stem cells and became expressed in cells entering meiosis.
