What are the downstream molecular targets of CX43-dependent STAT1 signaling that confer chemoresistance?

OPEN

The study identifies CX43-dependent STAT1 signaling as mediating astrocyte-induced chemoresistance but doesn't reveal the specific downstream effectors or target genes. Understanding these molecular targets is critical for developing combination therapies to overcome brain metastasis chemoresistance.
