RNAi Curation Mission Summary

The term "RNAi" stands for "RNA-interference" and refers to the targeted silencing of gene expression of a "target gene" via introduction of double stranded RNA (dsRNA) containing high degrees of sequence identity to the "target gene". In C. elegans, molecules of dsRNA may be introduced into the worm by a variety of different methods including direct micro-injection, soaking of worms in solution containing dsRNA, feeding worms bacteria that express dsRNA from a plasmid, and transgenic expression (within the worm) of dsRNA. For efficient and specific knockdown of gene expression, the dsRNA must have a minimum sequence identity with the target gene sequence. Any phenotype(s) resulting from the RNAi-mediated knockdown of a particular gene is thought to directly reflect the phenotype of a loss-of-function mutation in that gene, hence providing evidence as to the gene's biological function.

The goal of RNAi curation is to associate RNAi-mediated phenotypes with the target genes knocked down in RNAi experiments, as found in the literature pertaining to C. elegans and related species. There are some important things to consider when curating RNAi experiments. Some RNAi experiments are simple to curate as the strain is N2 (wild type genotype), only a single gene is targeted for RNAi, the phenotype is clearly stated, and the source and identity of the dsRNA is clearly stated by the authors. In many cases, however, the curation task is not so simple: there may be complex genotypes with multiple mutations in the strain receiving the dsRNA, multiple RNAi gene targets, complex genetic interactions, and/or missing descriptions from the authors as to controls, dsRNA delivery method, dsRNA identity, and/or phenotype directly resulting from the RNAi in question. Hopefully these issues will all be addressed below.

RNAi Curation Standard Operating Procedure (SOP)

In order to ensure consistency of RNAi curation across curators and WormBase releases, a set of standard procedures for RNAi curation are outlined below. The descriptions of these procedures include use of the two main methods for generating *.ace files for release submission: (1) the web-based CGI form for one-at-a-time RNAi object generation and (2) the batch form submission method.

Minimum Requirements for an RNAi Object

Regardless of which curation method you (the curator) choose, there are a set of minimum requirements in order to generate a complete RNAi experiment object:

1) A reference (e.g. WBPaperID)

2) A curator name

3) The sequence of the dsRNA used in the experiment to knockdown gene expression

4) A dsRNA delivery method (e.g. Injection) [Note: some authors omit this information. This can be curated arbitrarily and removed from the *.ace file once it has been generated]

5) A phenotype (observed or not_observed)

If any one of these five basic pieces of information are missing, the scripts that generate the *.ace file will fail, returning an error.

RNAi Paper Flagging and Processing of SVM "Low" Results and Tracking

We have been using SVM to flag papers that may contain RNAi data. These papers are given a probability score (High, Medium or Low) based on the SVM training set to reflect the possibility that they contain RNAi data to be curated. The High and Medium scoring papers are automatically added to the list of RNAi papers that are to be curated (on the Paper Editor) and the Lows are stored separately. The Low scoring papers must be manually checked by a curator and if the paper has "curatable" RNAi data, the curator must manually add that paper to the list. The Low scoring paper list is being checked approximately every 3 months (it is added to automatically every Monday at 2am based on SVM results). The following is the SOP for checking these papers and adding them to the list of RNAi papers to curate.

SVM Low's - SOP for checking papers

The file containing the papers with a low priority score (named "low") is stored on tazendra in the directory: /home/postgres/work/pgpopulation/svm/gary_rnai New papers are concatenated to this list. The curator checking the recently added papers must go back in the list to the most recent paper that has a "commented out" mark "//". This mark means that the list has been checked up to this point in the paper list....all papers after this mark need to be manually checked. When the curator is finished, they should "comment out" the last paper on the list so the next curator knows where to begin checking next time.

SVM Low's - SOP for adding papers to curation pipeline

After checking the "Low" papers, the ones that do conatin data must be added to the curation list. To do so go to the curator_first_pass.cgi on the web which is listed under "curation Forms" on the site map for tazendra. Add the appropriate number of the WBPaper id, for example just "00038308" without the WBPaper prefix, and click on the query button. Under "rnai" in the Gene Function section add the following comment in the curator box "SVM -LOW". When you hit "Flag" at the bottom of the page this paper will be added to the RNAi curation list and noted as an SVM with a low probability score.

SVM Low's - SOP for adding papers SVM Tracking

For tracking of SVM results (if False Positive, False Neg etc) a tool was created: http://XXXXXXXXX.caltech.edu/~postgres/cgi-bin/svm_results.cgi This web-based tool will automatically track papers that are positive based on our RNAi curation pipeline/checkout form and the OA; That is if a paper is on the checkout form and is curated, the data will be in the OA and marked as a True Positive. If the paper on the checkout list is a False Positive, the curator must note this on the paper editor (Flag False Positive) and the results will be forwarded to the SVM tracking form. http://tazendra.caltech.edu/~postgres/cgi-bin/paper_editor.cgi The SVM lows that do contain RNAi data are added to the checkout form by a curator (see above) and will be dealt with as any other paper on the list. The SVM lows that actually do not contain RNAi data must be entered manually onto the SVM tracking form as False Positives. To do this go to http://XXXXXXXXX.caltech.edu/~postgres/cgi-bin/svm_results.cgi Under "Enter Curator Results" Select data type/ select curator negative / add the list of negatives to / select comment "SVM positive - Curator negative"

NOTE: Warning: RNAi objects may have multiple lines in the OA due to the nested phenotype data (Penetrance info, etc.)

Dependency Notice: The Community Phenotype Form and the RNAi OA each have separate code to look up the most recent RNAi ID and generate new RNAi IDs based on that. If the code is changed for one, we should also check that the code is changed for the other.

  • When suggesting a new phenotype term in TAB 2 of the RNAi OA, curators should make sure to create a PGID/Row with a single placeholder phenotype that is intended to be replaced by the new phenotype term once the new term has been approved
  • If the data is dumped from the OA for upload before the new term has been approved, the object will dump with the placeholder phenotype term for that upload
  • This behavior is similar to that of the Phenotype OA
  • The data entered into the three fields "Phenotype Suggestion", "Suggested Definition", and/or "Child Of" will immediately be populated into the corresponding fields in the New Objects CGI
  • Cron job:

Runs every Sunday at 3 am, checking for entries in rna_suggested (and app_suggested) within the last 7 days and sends Gary S. an e-mail if there are any new entries. If there aren't any, there is no email.

In the OA, I think we should include: Person_evidence, Author_evidence, Curator_confirmed, Laboratory_evidence -- C We're only keeping Person_evidence for the #Evidence hash associated with the whole ?RNAi object -- C+J
  • Penetrance Incomplete - rna_penincomplete - Toggle I think we talked about this, but in case we didn't phenotype OA uses a dropdown for the 4 penetrance types instead of separate toggle fields -- J OK, this sounds like a good idea. Let's just make it a dropdown list here as well -- C
  • Penetrance Low - rna_penlow - Toggle
  • Penetrance High - rna_penhigh - Toggle
  • Penetrance Complete - rna_pencomplete - Toggle
  • Method - rna_method - Method - Text


Fields for the tags "Predicted_gene", "Gene", "Transcript", "Pseudogene", "Homol_homol" and "Uniquely_mapped" will be omitted from the OA and populated in ACEDB after probe mapping to the genome at the EBI during the build process.

*.ACE Dumper Documentation

Each RNAi object will need to get dumped with "RNAi" in the "Method" tag

On tazendra, perl module is /home/postgres/work/citace_upload/rnai/get_rnai_ace.pm

Run with script /home/postgres/work/citace_upload/rnai/use_package.pl

Generates rnai.ace.<date> and err.out.<date> (to the day, so it will overwrite previous dumps from the same date) please check dumper and .ace file dumped -- J The dumper seems to be working OK since the dumped *.ACE file you generated is reading in OK, except for the "Evidence" line, as I comment about above in the "Tab3" section. The line currently dumps out as "Person_evidence ..." and it needs to dump out as "Evidence Person_evidence ...", otherwise the file throws errors when reading into ACEDB -- C Fixed, I thought only the innermost tag mattered, but I guess because there's no data in the RNAi part, just the tag, it needs to be there before the #Evidence part -- J I believe so, yes. -- C

Use_package.pl line comments:

'my $outfile = 'rnai.ace.' . $date;' 'my $errfile = 'err.out.' . $date;'

  • These lines (above) specify the output; change as necessary.

'my ($all_entry, $long_text, $err_text) = &getRnai('all');'

'# my ($all_entry, $long_text, $err_text) = &getRnai('WBRNAi00008227');'

  • The lines above specify what to dump out of the OA. 'all' dumps everything. If you want to dump specific objects, comment out the top line (add a '#') and uncomment the bottom line (remove '#') and specify the object name where 'WBRNAi00008227' is. Because of permissions, the script will need to be copied, modified, and then run from a permissible directory.

Molecule now converts the pgid stored in postgres with the molecule name in mop_name for that pgid -- J

Error Checks During Dump Process

The following is a list of checks that the .ACE dumper script will perform on all RNAi objects being dumped out of the OA to make sure that the data is consistent and doesn't have any nonsensical information. Any errors that are found will be printed to an "err" file. Every line of the file will list an error message of the general format:

PGID  <TAB>  Dump_status  <TAB>  Curator ID  <TAB>  Explanation

where "Dump_status" could be "nodump" (for objects that have a 'fatal' error and will not be dumped) or "flagonly" (for objects that have a 'non-fatal' error and will be dumped).

Fatal Errors (RNAi objects will not get dumped)

1) If there is no identifying RNAi probe information (i.e. the sequence or clone used to knockdown the target gene) in an RNAi object, the dumper script will generate an error message that is printed to the ERROR output file and the object will not get dumped. This is determined by checking that:

a) There is at least one "PCR Product" entry OR

b) There is at least one "DNA Text" entry OR

c) There is at least one "Sequence" entry

If none of these conditions hold true, then an error message will be printed in tab-delimited format like this:

12345   nodump    WBPerson1234   There is no sequence, neither pcrproduct nor dnatext nor sequence

2) If there is no reference (Paper or Person) then the object will not get dumped and an error message is printed:

12345   nodump    WBPerson1234   There is no reference, neither paper nor person

3) If there is no "Phenotype" specified by the curator, the object will not get dumped and an error message will print to the ERROR output file like this:

12345   nodump    WBPerson1234   There is no phenotype

4) If there is no RNAi ID, the object will not get dumped and an error message will print to the ERROR output file like this:

12345   nodump    WBPerson1234   There is no RNAi ID

Non-Fatal Errors (RNAi objects will get dumped, but error message will get printed)

1) If there is no dsRNA "Delivery Method" that has been specified by the curator, the RNAi object will get dumped to the .ACE file, but an error message will print to the ERROR output file like this:

12345   flagonly    WBPerson1234   There is no deliverymethod

2) If there is no "Species" specified by the curator, the RNAi object will get dumped to the .ACE file, but an error message will print to the ERROR output file like this:

12345   flagonly   WBPerson1234   There is no species

3) If no curator is listed for the RNAi object, the RNAi object will get dumped, but an error message will print to the ERROR output file like this:

12345   flagonly   no curator   has no curator
