Description…

TSPO is a conserved protein found at the outer mitochondrial membrane. TSPO interacts with some benzodiazepines and isoquinoline carboxamides and has different affinities than its endogenous counterpart. TSPO is also involved in the transport of porphyrins and heme.

Attributes

Phase: Two
QA State: Under Review

Overview

The TSPO gene is known to be over-expressed in highly aggressive tumors, especially those of the breast. Increasing levels of the TSPO protein are correlated with more advanced stages of breast cancer. Higher TSPO levels are found in estrogen receptor (ER)-negative breast tumors, compared with ER-positive tumors.

Performance Comment

TSPO was one of numerous potential early detection biomarkers specific to triple-negative breast cancer in multiple pathways identified.
