Multidrug Resistance Pathway

Molecular classification
Pathway
01

Overview

The multidrug resistance pathway encompasses diverse molecular strategies enabling cells—especially tumor cells—to evade the effects of multiple therapeutic agents through mechanisms such as increased drug efflux via ABC transporters like P‑glycoprotein/MDR1. This remains a critical target for research into overcoming treatment failures in both oncology and infectious disease settings.
