Cancer-Alterome

In the quest to unravel the intricate mechanisms underlying tumors, understanding cancer is crucial for developing effective treatments. In this project, Cancer-Alterome, addresses this challenge by presenting a literature-mined dataset focusing on the regulatory events within an organism's biological processes or clinical phenotypes induced by genetic alterations.

The repository includes the complete pipeline implementation for the Cancer-Alterome construction, basically used to extract the Genetic Alteration caused Regulatory Events (GARE), as well as the script for generating the data visualization in MS.

If the work is useful to you, please refer to the citation.

Environment Configuration

Python Version

This project is developed using Python 3.6+.

Python Libraries

The Pipeline implementation relies on the underlying python library, e.g. numpy, scipy, nltk, Pyecharts. You can install these library via pip install <library> or conda install <library>.


External Tools

The pipeline implementation involves several external tools, the description and links of these tools are provided below. Users may need to configure and test these tools before running the full Cancer-Alterome pipeline.

  • PubTator Central: This tool are used to identify and standardize genes, point mutations, single nucleotide mutations, and disease mentions in pipeline.

  • AGAC-NER: This model are used to identify the genetic alteration and trigger word defined in AGAC corpus.

  • AGAC-RE: This model are used to identify the genetic alteration and trigger word defined in AGAC corpus.

  • OGER++: This model are used to extract the relations defined in AGAC corpus, include \textit{Theme} and \textit{Cause}.

  • PhenoTagger: This tool are used to identify the mentions of GO concepts in the text, and normalize mentions to GO IDs.


Pipeline Usage

All 16 backbone scripts for each step in pipeline are released in this repository, and the script names are numbered indicating the running order. The usages of the script are listed below.

1. Literature Preparation

The LiteraturePrepare folder contains 5 scripts.

  • 1. get_pmc_pmid.py and 1.1 esearch_get_pmc_pmid.py is used to search PubMed and PubMed Central databases based on keywords and to download PMID and PMCID.

  • 2. pmc_pmid_to_biocjson.py is used to automatically download the abstracts as well as full text of the corresponding literature from PubMed Central's API based on the PMIDs and PMCIDs obtained in the previous step, and includes the PubTator annotation.

  • 3. biocjson_to_pubtator.py provides PubTator format conversion of BiocJson format files. This conversion step is necessary due to the pipeline design where the PubTator format is used for subsequent data processing.

  • 4. biocjson_to_jounral_info.py is used to extract the journal information of the article from the BiocJson format file, e.g. journal name, the year of publication.

2. Named Entity Recognition and Normalization.

The NamedEntityRecognization folder contains 6 scripts with the following usage guidelines.

It should be noted that since AGAC-NER already have independent repositories, only the format conversion scripts for they input and output are provided here.

In addition, before using OGER++ and PhenoTagger, you may need to visit their project websites and configure the tool environment.

  • 1. pubtator_to_agac_ner_input.py provides the conversion of PubTator format documentation to AGAC-NER model input format.

  • 2. agac_ner_output_procss.py is used to process the output file of the AGAC-NER task.

  • 3. oger_tagger.py provides batch GO concept annotation by using OGER++. The vocabularies files required for OGER++ are also provided in go.term.tsv and hpo.term.tsv.

  • 4. OGER_result_process.py provides the result processing for OGER++ results.

  • 5. PhenoTagger_training.py provides the model training function of PhenoTagger.

  • 6. PhenoTagger_tagging.py is used to batch tagging the HPO concepts by using PhenoTagger.

3. Relation Extraction

In the RelationExtraction folder, 2 scripts are provided with the following usages. Similarly, you can find the usages for AGAC-RE in it's repositories.

  • 1. ner_tagging_to_agac_re_input.py provides the format conversion of the AGAC-NER output to the AGAC-RE inputs.

  • 2. agac_re_infer_process.py is used to process the prediction results of AGAC-RE.

4. Regulatory Events Extraction

The GARE-Extraction folder contains one script.

  • 1. rule_based_gare_extraction.py is used to extract the complete GARE from the above steps based on the design rules of GARE.

5. Data Visualization

The DatabasePrepare folder contains 3 scripts for data format conversion and visualization.

  • 1. gare_to_database.py is used to convert the GARE results generated in the previous step into a more readable tab-delimited database format.

  • 2. multi-gene-heatmap.ipynb is used to plot the heatmap web page visualization shown in the literature.

  • 3. Signle_gene_SanKey.ipynb is used to plot the SanKey web page visualization presented in the literature.

5. OpenAI Evaluation

There are 3 script and 5 prompts are used for OpenAI LLM evaluation.

  • 1. gpt_query_xzyao.py used to batch request the OpenAI API using prompt and save the response results.

  • 2. chatgpt_ner_eval.py used to evaluate the NER annotation results returned by the API.

  • 3. chatgpt_re_eval.py used to evaluate the RE annotation results returned by the API.

  • 4. event-generation-evaluation.py used to evaluate GARE generation results returned by the API.
