Progenetix is an open data resource that provides curated individual cancer copy number variation (CNV) profiles along with associated metadata sourced from published oncogenomic studies and various data repositories. This vignette provides a comprehensive guide on accessing and utilizing metadata for samples or their corresponding individuals within the Progenetix database.

If your focus lies in cancer cell lines, you can access data from cancercelllines.org by setting the domain parameter to "https://cancercelllines.org" in pgxLoader function. This data repository originates from CNV profiling data of cell lines initially collected as part of Progenetix and currently includes additional types of genomic mutations.

Load library

library(pgxRpi)

`pgxLoader` function

This function loads various data from Progenetix database via the Beacon v2 API with some extensions (BeaconPlus).

The parameters of this function used in this tutorial:

type: A string specifying output data type. "individuals", "biosamples", "analyses", "filtering_terms", and "counts" are used in this tutorial.
filters: Identifiers used in public repositories, bio-ontology terms, or custom terms such as c("NCIT:C7376", "PMID:22824167"). When multiple filters are used, they are combined using AND logic when the parameter type is "individuals", "biosamples", or "analyses"; OR logic when the parameter type is "counts".
individual_id: Identifiers used in the query database for identifying individuals.
biosample_id: Identifiers used in the query database for identifying biosamples.
codematches: A logical value determining whether to exclude samples from child concepts of specified filters in the ontology tree. If TRUE, only samples exactly matching the specified filters will be included. Do not use this parameter when filters include ontology-irrelevant filters such as PMID and cohort identifiers. Default is FALSE.
limit: Integer to specify the number of returned profiles. Default is 0 (return all).
skip: Integer to specify the number of skipped profiles. E.g. if skip = 2, limit=500, the first 2*500=1000 profiles are skipped and the next 500 profiles are returned. Default is 0 (no skip).
dataset: A string specifying the dataset to query from the Beacon response. Default is NULL, which includes results from all datasets.
domain: A string specifying the domain of the query data resource. Default is "http://progenetix.org".
entry_point: A string specifying the entry point of the Beacon v2 API. Default is "beacon", resulting in the endpoint being "http://progenetix.org/beacon".
num_cores: An integer specifying the number of cores to use for parallel processing during Beacon v2 phenotypic/meta-data queries from multiple domains. Default is 1.

Retrieve biosamples information

Search by filters

Filters are a significant enhancement to the Beacon query API, providing a mechanism for specifying rules to select records based on their field values. To learn more about how to utilize filters in Progenetix, please refer to the documentation.

The following example demonstrates how to access all available filters in Progenetix:

all_filters <- pgxLoader(type="filtering_terms")
head(all_filters)
#>                           id                      label         type scopes
#> 1        EDAM:operation_3227        EDAM:operation_3227 ontologyTerm     NA
#> 2        EDAM:operation_3961        EDAM:operation_3961 ontologyTerm     NA
#> 3 labelSeg-based calibration labelSeg-based calibration alphanumeric     NA
#> 4                NCIT:C28076    Disease Grade Qualifier ontologyTerm     NA
#> 5                NCIT:C18000           Histologic Grade ontologyTerm     NA
#> 6                NCIT:C14158                 High Grade ontologyTerm     NA

The following query retrieves information about all retinoblastoma samples in Progenetix, utilizing a specific filter based on an NCIt code as a disease identifier.

biosamples <- pgxLoader(type="biosamples", filters = "NCIT:C7541")

The data contains many columns representing different aspects of sample information.

Search by biosample id and individual id

In the Beacon v2 specification, biosample id and individual id are unique identifiers for biosamples and their corresponding individuals, respectively. These identifiers can be obtained through metadata searches using filters as described above or by querying the Progenetix search interface, which provides access to the IDs used in the Progenetix database.

It’s also possible to query by a combination of filters, biosample id, and individual id.

Access a subset of samples

By default, it returns all related samples (limit=0). You can access a subset of them via the parameter limit and skip. For example, if you want to access the first 10 samples , you can set limit = 10, skip = 0.

biosamples_3 <- pgxLoader(type="biosamples", filters = "NCIT:C7541",skip=0, limit = 10)
# Dimension: Number of samples * features
print(dim(biosamples))
#> [1] 256  42
print(dim(biosamples_3))
#> [1] 10 42

Parameter `codematches` use

Some filters, such as NCIt codes, are hierarchical. As a result, retrieved samples may include not only the specified filters but also their child terms.

unique(biosamples$histological_diagnosis_id)
#> [1] "NCIT:C7541" "NCIT:C8714" "NCIT:C8713"

Setting codematches as TRUE allows this function to only return biosamples that exactly match the specified filter, excluding child terms.

biosamples_4 <- pgxLoader(type="biosamples", filters = "NCIT:C7541",codematches = TRUE)
unique(biosamples_4$histological_diagnosis_id)
#> [1] "NCIT:C7541"

Query from multiple data resources

You can query data from multiple resources via the Beacon v2 API by setting the domain and entry_point parameters accordingly. To speed up the process, use the num_cores parameter to enable parallel processing across different domains.

biosamples_5 <- pgxLoader(type="biosamples",filters = "NCIT:C7541",domain=c("progenetix.org","cancercelllines.org"), entry_point="beacon") # both resources use the same entry point

Retrieve individuals information

If you want to query details of individuals (e.g. clinical data) where the samples of interest come from, set the parameter type to “individuals” and follow the same steps as above.

individuals <- pgxLoader(type="individuals",individual_id = "pgxind-kftx26ml",filters="NCIT:C7541")
# data looks like this
tail(individuals,2)
#>       individual_id      sex_id sex_label age_iso histological_diagnosis_id

#> 255 2018-09-26 09:50:52.800000            <NA>            <NA>

Retrieve analyses information

If you want to know more details about data analyses, set the parameter type to “analyses”. The other steps are the same, except the parameter codematches is not available because analyses data do not include filter information, even though it can be searched by filters.

analyses <- pgxLoader(type="analyses",biosample_id = c("pgxbs-kftvik5i","pgxbs-kftvik96"))

Retrieve the number of results for a specific filter

To retrieve the number of results for a specific filter in Progenetix, set the type parameter to "counts". You can query different Beacon v2 resources by setting the domain and entry_point parameters accordingly.

pgxLoader(type="counts",filters = "NCIT:C7541")
#>       filter      entity count
#> 1 NCIT:C7541 individuals   254
#> 2 NCIT:C7541  biosamples   256
#> 3 NCIT:C7541    analyses   276

Visualization of survival data

Suppose you want to investigate whether there are survival differences associated with a particular disease, for example, between younger and older patients, or based on other variables. You can query and visualize the relevant information using the pgxMetaplot function.

`pgxMetaplot` function

This function generates a survival plot using metadata of individuals obtained by the pgxLoader function.

The parameters of this function:

data: The data frame returned by the pgxLoader function, containing survival data for individuals. The survival state is represented by Experimental Factor Ontology in the “followup_state_id” column, and the survival time is represented in ISO 8601 duration format in the “followup_time” column.
group_id: A string specifying which column is used for grouping in the Kaplan-Meier plot.
condition: A string for splitting individuals into younger and older groups, following the ISO 8601 duration format. Only used if group_id is “age_iso”.
return_data: A logical value determining whether to return the metadata used for plotting. Default is FALSE.
...: Other parameters relevant to KM plot. These include pval, pval.coord, pval.method, conf.int, linetype, and palette (see ggsurvplot function from survminer package)

Example usage

# query metadata of individuals with lung adenocarcinoma
luad_inds <- pgxLoader(type="individuals",filters="NCIT:C3512")
# use 70 years old as the splitting condition
pgxMetaplot(data=luad_inds, group_id="age_iso", condition="P70Y", pval=TRUE)

It’s noted that not all individuals have available survival data. If you set return_data to TRUE, the function will return the metadata of individuals used for the plot.
