TXNDC9 and squamous cell carcinoma: Recently, it was found that UV-B-irradiated squamous-cell carcinoma cells exploit Thioredoxin domain-containing protein 9 (TXNDC9) to facilitate IκBα phosphorylation and p65 translocation, promoting survival; knocking down TXNDC9 restores apoptosis and impairs NF-κB activation [155].
