QPCR Data Relevant to Endomesoderm Network

Perturbation Ct:[Ub-C]-[Ub-Exp]

May 18, 2010

Ub, ubiquitin mRNA control used for internal standardization; CT, cycle no. at threshold; C, control embryo sample; Exp, sample from perturbed embryos. The quantity of transcript at any point in the reaction is I(1.94CT), where I is the initial amount in the reaction mixture. A positive number means the number of transcripts is increased by the perturbation; a negative number means the number of transcripts is decreased. Data are listed that are considered significant where significant means more than three-fold increase or decrease from control transcript levels (normalized CT difference from control is <-1.6 or >+1.6). Smaller effects are shown as "NS", except where individual NS data are included together with other significant measurements to display scatter or inconsistencies amongst different batches of cDNA. Commas separate replicate measurements in the same cDNA batch; slashes indicate different batches of cDNA from independent experiments.


Note: Smaller effects are shown as "NS", except where individual NS data are included together with other significant measurements to display scatter or inconsistencies amongst different batches of cDNA. Commas separate replicate measurements in the same cDNA batch; slashes indicate different batches of cDNA from independent experiments, dashes indicate a missing data point

Footnotes

1Must be affected indirectly via intercellular signaling because Bra is not present in cells where these genes are active.

2At 30 h affected indirectly via cell signaling, since at 30 h Dri and Gsc are expressed only in OE.

3Thought to be indirect input, via GataE.

4Probably via GataC.

5Probably via Bra.

6Probably in OE where both Elk and Lim1 are expressed then.

7Probably indirect via Gcm.

8Probably indirect via gcm.

9The inputs inferred from effects on endo16.

10Effect on endo16 is via Ui since no necessary GataE site in endo16.

11Probably via ets1; based on ECRA.

12Indirect, because rescued by blimp1 MOE.

14Probably indirect via elk.

15Weak effect 18 h only, probably not significant, since wnt8 expression is disappearing in gatae domain at 18 h. Effect seen is probably via Otx which represses wnt8 in this period.

17Likely indirect via gatae.

18Late Krl effects likely to be indirect results of effects of Krl loss on endomesoderm specification (Howard et al., 2000).

19Obviously indirect via pmar1.

20Only when dri is expressed in OE (>30 h).

21Possibly indirect via, because if there were an Otx site in gatac gene effect would have been seen earlier than 24 h.

22Must be indirect because direct sm50 inputs are known.

23Normalized to different standards in same run, i.e., ubiquitin and 18S rRNA.

24 alx1 expressed specifically in pmc's; discovered by Ettensohn et al.

26In collaboration with R. and L. Angerer who provided the samples measured.

27Likely an artifact of expressing Blimp1-En MOE pmc's, since foxb is expressed only in pmc's at this stage (i.e., there could be a later interaction of Blimp1 and Soxb in hindgut where they are both expressed after gastrulation).

28Weak effect likely indirect since gatac is expressed in smc's at 27 h and foxb in pmc's, later hindgut on oral side (plus oral ectoderm).

30Not indirect via GataE because N MASO does not affect gatac though dnN does.

31Indirect effects on gatac does not turn on until after Tcf input is faded out, but all other inputs depend on endomesoderm specification.

32Effect on initial phase of gatac expression, before it becomes exclusive with gcm (oral vs aboral and lateral).

33Could be indirect via Ets1 effect on tbr; effect of Ets1 on foxb is stronger than tbr effect on foxb.

34At least early (<24 h) effects on the three fvmo genes probably via gcm.

35Via dri (see Amore et al., 2002).

37Implies late blastula pmc domain to mesoderm indirect effect on oral side, where gatac is then expressed in mesoderm: not yet understood.

38Since Gsc is a repressor (Angerer et al.) implies existence of mid-late blastula repressor of skeletogenic function controlled by gsc: perhaps a timing device.

40Very possibly indirect via dri.

41Unlikely a direct transcriptional effect, since eve expression is not affected by Soxb1-Eng MOE.

42Possibly indirect.

43Likely via dri.

45Probably in OE because most gsc expression at 24 h is there.

47Double perturbation results show both inputs, Alx1 and Ets1, are required when indicated.

48Data for mesenchyme blastula stage of Lytechinus variegatus

49Probably Indirect

50Unc4.1 is expressed in the aboral veg1 ectoderm, starting at 24h; effect must be indirect
