The Information Updated to the Latest VARIDT 3.0

Current VARIDT Covered 424 Drug Transporters (DTs)/potential DTs Transporting 585 FDA Approved and 301 Clinical/Preclinical Drugs for 572 Diseases

Five Aspects of Phenotypic and Regulatory Variability are Provided for Each DT in VARIDT 3.0 (Graphic Illustration) :

α. Microbiota Influence (MBI) of DTs

2,072 MBI data of 145 DTs regulated by 124 microbe species, and the relative abundances of these microbe species across 76 diseases

β. Post-Translational Modification (PTM) of DTs

10,255 PTM data of 418 DTs that were related to 24 PTM types, and graphical illustrations on 9,717 experimentally-validated PTM sites

γ. Transcriptional Regulation (TSR) of DTs

10,610 TSR data of 381 DTs that were regulated by 357 TFs, and the differential expression profiles of these TFs across 59 organs and 106 diseases

δ. Epigenetic Regulation (EGR) of DTs

46,748 EGR data of 287 DTs related to 3 types of EGR

ε. Exogenous Modulation (EGM) of DTs

12,209 EGM data of 419 DTs modulated by 1,717 xenobiotics

Data Standardization in VARIDT 3.0 Facilitating Comprehensive Health Management :

1. Diseases Affected by the Drugs of Clinical Importance

All diseases were standardized using the latest version of International Classification of Diseases (ICD-11, released by the WHO)

2. Functional Family of Each Drug Transporter (DT)

Functional family of each DT was standardized using the phylogenetic classification of Transporter Classification Database (TCDB)

3. Unit of Kinetic Parameter (Km value) for Transporting Drugs

The affinity measured by Km value for the drugs transported by their corresponding DTs were unified to the unit of micromolar

4. 2D and 3D Structures of Small Molecular Drugs

The structures of the small molecular drugs transported by DTs were drawn and were standardized in the .sdf format (both 2D and 3D)

5. Crosslinking with Other Biological/Pharmaceutical Databases

UniProtKB, TCDB, dbSNP, Drugs@FDA,, ICD-11, PubChem, ChEBI, TTD, NCBI Gene, CAS Registry Number, etc.
