CHRNA2 and gastric cancer: YBX1 has been associated with several human cancers, e.g., colorectal cancer, breast cancer, and glioblastome multiforme.[30–32] RPL15 is overexpressed and seems to be involved in cell proliferation in gastric cancer.[33] CHRNA2 is located on chromosome 8p, a chromosomal region with 484 detected genes.
