CSRP2 and cancer: Of these, some were differentially expressed in both insulin-expressing populations, including ENSCAFG00000037735 (TMSB4X) and CSRP2. The functions of these genes in this context are not clear, but CSRP2 has been associated with cancer cell stemness [51] and TMSB4X has been proposed as a cancer prognostic marker [47].
