BipotentR



BipotentR identifies targets for bipotent drugs – single drugs that can kill cancer by multiple mechanisms. BipotentR was developed to address the low response rates to existing therapies targeting single mechanisms that also suffer from high relapse rates due to evolved resistance to single mechanisms. It allows researchers to systematically identify bipotent targets whose inhibition act against advanced and resistant cancers by inducing immunity and suppressing an input oncogenic pathway. BipotentR identified bipotent immunotherapeutic targets that also regulate other hallmark cancer pathways, including energy metabolism (38 immune-metabolic regulators), angiogenesis (14 regulators), and evasion of growth suppressor (14 regulators).

The website provides an interface to explore bipotent gene regulators that modulate antitumor immunity and input pathways (among KEGG pathways).

For identifying bipotent regulator of any other input pathway, the website also contains detailed instructions for downloading and using a R package for more advanced applications.


Machine learning based estimation of bipotent targets

Please use the [BTAS website] to access machine learning and deep learning models which estimate tumor activity of bipotent target that are predictive of immunotherapy response for melanoma patients.

Standalone (R and Python based) software of BTAS is available [here.]

For reprodicibility, data and code from the manuscript are shared publicly at Zenodo

Bulk and single RNA-seq data generated from the current study are available at [RNA-seq] and will be submitted to a public repository upon publication.

Introduction to BipotentR package

Below, we describe instruction to setup R package of BipotentR. The following tutorial is designed to BipotentR pacakge overview of the kinds of comparative analyses on complex cell types that are possible using the Seurat integration procedure. Here, we address a few key goals:

  • Install BipotentR R package
  • Download reference data
  • Identify bipotent targets of CITRATE CYCLE and immune response using BipotentR

Install

library(devtools)
install_github("vinash85/TRIM")

Download reference dataset

The hdf5 file for cistrome dataset is downloaded by download.data.

library(TRIM)
download.data()

Run BipotentR

Here we describe running the package for CITRATE CYCLE as a input pathway. The genes within TCA cycle is stored in the variable c2.kegg. BipotentR is main function of the package. The outputs will be stored in bipotent.targets

tca.pathway =  c2.kegg[c2.kegg$term=="KEGG_CITRATE_CYCLE_TCA_CYCLE",]$gene  
## default location download.data store file
cistrome.hdf5.path =  sprintf("%s/data//human_100kRP.hd5", system.file(package = "TRIM")) 
bipotent.targets = BipotentR(tca.pathway, cistrome.hdf5.path)

Github

The R package is available in github at BipotentR package.
