13 Expression Patterns

• Primary Identifier: Expr11300
• Pattern: Strong expression at all stages (starting in the embryo), vulval epithelium, spermatheca, uterus, arcade cells?, CEPsh?, several unidentified head cells

• Primary Identifier: Marker30
• Remark: Picture: Fig. 1G, 1H, Fig S1G-L.
• Pattern: Expressed in CEPsh glia and in sheath and socket glia of inner and outer labial sensilla, and of the deirid.

• Primary Identifier: Marker29
• Remark: Picture: 1F.
• Pattern: Expressed in CEPsh cells at all developmental stages and in some motoneurons of the ventral cord in larvae.

• Primary Identifier: Expr8673
• Remark: Picture: Fig 3.
• Pattern: Expression in the alimentary canal: Strong and consistent expression in anterior arcades, posterior arcades, M1, B cell. Weak or rare expression in intestine. Expression in the nervous system: Amsh, CEPsh, CEPso, ILso, OLso, Phso, DVC, MI. Expression in the reproductive system: In adult stage, expressed in gonad sheath, uterus, vulva(low), spermatheca, Sp-ut valve. In developing larva stage, expressed in uterus, vulva, spermatheca, Sp-ut valve. inx-5 first appears in the developing hypodermis at bean stage and then in the excretory cell at three-fold stage.

• Primary Identifier: Expr9325
• Pattern: Synaptogyrin is expressed in all 26 GABAergic neurons including also RMER and most though not all other neurons. Synaptogyrin is absent in amphids and phasmids and can be detected in non-neuronal glial-like sheath cells in adult worms. The cephalic neurons CEPDR/L and CEPVR/L and amphid-associated sheath cells CEPshDR/L, CEPshVR/L were tentatively positive. Several other neurons that could be tentatively identified in the anterior part are MI, M4, I4, AVL, AIY, RIS, I5, M3R/L, and in the posterior part DVA, AS11, ALNR/L, DVC, DVB, PQR, DA9 (characteristic axonal process denoted by arrowhead), VD13, DD6, VD12. Of these, AVL, RIS, VD13, DD6 and VD12 are GABAergic based on the colocalization with the unc-47p::GFP reporter. In addition, IL neurons were tentatively identified in the anterior (IL*). Synaptogyrin reporter constructs are also expressed in developing neurons. The expression of sng-1p::YFP is closely associated with the development of the nervous system being absent in the gastrula stage with first fluorescence in neuronal precursor cells and newly-formed neurons in the anterior part during the 1.5-fold stage. In addition, it is also detected transiently in cells in the posterior body at the 1.25-fold and 1.5-fold stage.

• Primary Identifier: Expr14560
• Pattern: Strong glt-1 GFP expression is observed in all four CEPsh glia. Weaker expression is also detected in muscles, consistent with a previous report.

• Primary Identifier: Expr1181
• Pattern: CEP sheath cells; excretory gland cell; pharynx; intestine.

• Primary Identifier: Expr8671
• Remark: Picture: Fig 3.
• Pattern: Expression in the alimentary canal: Strong and consistent expression in pharyngeal epithelium, pm5, pm6, pm7, pm8, g2, rectal gland cells. Weak or rare expression in anterior arcades, posterior arcades, pm2, pm3, pm4, M3, MC, intestine, rectal epithelial cells. Expression in the nervous system: CEPsh, ALN, ASn, CAN, DAn, DBn, DDn, DVA, DVB, HSN, PDE, PLM, PVQ, PVR, PVT, URB, VAn, VBn, VDn, M3, MC. Expression in the reproductive system: In adult stage, expressed in spermatheca, vulval muscle, HSN. In developing larva stage, expressed in vulval muscle, uterine muscle, HSN. inx-3 was expressed broadly during early embryogenesis. After the beginning of morphogenesis, inx-3 expression becomes more restricted to the pharynx, hypodermis, and intestine. By three-fold stage inx-3 expression appears in ventral cord motor neurons (strongest in DA neurons) along with continued strong pharyngeal expression. By hatching, its hypodermal expression disappears, while postembryonically born ventral cord motor neurons express it at low levels. Its pharyngeal (strong) and neuronal (faint) expressions continue to adulthood.

• Primary Identifier: Expr8679
• Remark: Picture: Fig 3.
• Pattern: Expression in the alimentary canal: Strong and consistent expression in anterior arcades, posterior arcades, pharyngeal epithelium, pm4, pm8, g1, g2, vir, K.a/K' cells. inx-11 is more strongly expressed in the most posterior (int 9) intestinal cell. Weak or rare expression in pm1, pm2, pm3, pm5, pm6, pm7. Expression in the nervous system: CEPsh, DVC, LUA. Expression in the reproductive system: In adult stage, expressed in utse. In developing larva stage, expressed in uterus, sperm (spermatocytes, spermatids). Expression of inx-11 appears in pharyngeal tissue around two-fold stage, and by three-fold stage, strong expression becomes restricted to g1, g2, pm4, and pm8. inx-11 is expressed in the hypodermal cells of the animal in postembryonic stages.

• Primary Identifier: Expr8681
• Remark: Picture: N.A.
• Pattern: Arcade cells are seen to express inx-13 at high levels starting around two-fold stage continuing throughout development and adulthood. inx-13 is expressed in the hypodermal cells of the animal in postembryonic stages. Expression in the alimentary canal: Strong and consistent expression in M1, M2. Weak or rare expression in intestine, rectal epithelial cells. Expression in the nervous system: Amsh, CEPsh, CEPso, ILsh, ILso, OLsh, OLso, Phsh, CAN, DVA, DVB, DVC, LUA, PHA, PHB, PLN, PVC, PVQ, PVR, M1, M2. Expression in the reproductive system: In adult stage, expressed in spermatheca, sp-ut valve.

• Remark: Picture: N.A.
• Pattern: Expressed in anterior intestine (most cells), major hypodermis, CEPsh, AMsh, PHsh.

• Primary Identifier: Expr2784
• Remark: Protein_Description: ICB4 antigen.
• Pattern: Antigen expressed in chemosensory neruons (inner labial 2, cephalic companion cell, and possibly ray neruon B), intestine and sperm.

• Primary Identifier: Expr3312
• Pattern: GFP expression was detected in four cells near the nerve ring as well as in two dendrites that extend toward the mouth displaying a pattern similar to that seen in C. elegans when amphid neurons are stained. The GFP shows a web-like pattern that seems to extend away from each of the cells. Weak GFP expression can also be seen in cells of developing embryos. These cells were identified as sheath cells of the cephalic sensilla. Expression in these cells is detected at all developmental stages and in both males and hermaphrodites.
