Regulated By Treatment	Description	Algorithm	Primary Identifier
	oocyte proteins identified by two or more unique peptides during proteomics study.	In the pooled data set, 1453 C. elegans proteins were identified with a probability >= 0.9 according to ProteinProphet, of which 1165 proteins were identified by more than one unique peptide.

	Genes that showed expression levels higher than the corresponding reference sample (embryonic 24hr 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.

8 Expression Patterns

• Primary Identifier: Expr1031321
• Pattern: Tiling arrays expression graphs

• Primary Identifier: Expr1019727
• Pattern: Developmental gene expression time-course. Raw data can be downloaded from ftp://caltech.wormbase.org/pub/wormbase/datasets-published/levin2012

• Primary Identifier: Expr3984
• Remark: The expression patterns of lam-1 and lam-2 are identical during embryogenesis.
• Pattern: Expression of is first detected in the nucleus of cells as they move inward into the gastrula. As the cells arrange into the endodermal and mesodermal layers, mRNAs are detected within cytoplasm. Expression continues as the intestinal cells and the precursors of the pharynx form a central cylinder with the myoblasts filling in between this cylinder and the outer layer of cells. Strong expression is detected in the myoblasts. The expression in the pharyngeal and the intestinal cells is relatively weak.
• Subcellular Localization: Expressed in nucleus and later in cytoplasm.

• Primary Identifier: Expr2013007
• Pattern: Single cell embryonic expression. Only cell types with an expression fraction of greater 0.2 of the maximum expressed fraction are labeled (Full data can be downloaded from http://caltech.wormbase.org/pub/wormbase/datasets-published/packer2019/). The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type.

• Primary Identifier: Expr10827
• Pattern: LAM-3/Laminin alpha-A immunostaining was evident between the germ layers, including on most surfaces of the endoderm. In particular, LAM-3 localized around the surfaces of the endoderm row 8 cells, just before and as the somatic gonad precursors (SGPs) extended projections between the anterior surfaces of these endoderm cells and the posterior surfaces of the primordial germ cells (PGCs). A functional LAM-1-GFP fusion protein showed a pattern of localization similar to LAM-3, including around the gonadal primordium at later stages. Therefore, laminin basement membrane is present on endodermal surfaces where the SGPs migrate and extend projections around the PGCs.
