OESOPHAGEAL CANCER: RNA editing of SLC22A3 mRNAs: causative relevance to familial ESCC?
A new study reveals an involvement of SLC22A3 in the development of familial oesophageal squamous cell carcinoma (ESCC). Reduced expression of SLC22A3 is detected not only in ESCC tumours but also in non-tumour tissues of patients with familial ESCC. Interestingly, adenosine-to-inosine editing of SLC22A3 mRNA is proposed to drive early tumour invasion and metastasis, by inhibiting SLC22A3 expression.
