MRP1, Multidrug Resistance Protein 1: Click to Expand ⟱
Source:
Type:
Multidrug resistance protein 1 (MRP1) encoded by ABCC1.
MRP1 levels are elevated in numerous cancer types, NSCLC, breast cancer, and prostate cancer Multidrug Resistance Protein 1 (MDR1), also known as P-glycoprotein (P-gp) or ABCB1, is a membrane protein that functions as an efflux pump, transporting a variety of drugs and xenobiotics out of cells. Its expression is a significant factor in the development of multidrug resistance (MDR) in cancer therapy.

Resistance Protein 1 (MDR1) is often upregulated in various cancers, and its high expression is associated with poor prognosis and protumorigenic effects due to its role in drug resistance.

*P-gp↓, Both in vitro and in vivo studies have shown that borneol inhibited the expression of P-gp and other ABC transporters,
