The impact of circRNAs targeting CD47 on cancer has been reviewed in the reference [28], which mentions that circRERE (hsa_circ_0009581) promotes the resistance to chemotherapy drug bortezomib (BTZ) in multiple myeloma (MM) via sponging miR-152-3p to upregulate the expression of CD47 [297]. Here, CD47 is linked to AL amyloidosis.
