LAMA4 and gastric cancer: LAMA4[circle112550019-112550510] is formed by the circularization of a DNA fragment within LAMA4. LAMA4 plays a role in promoting tumor cell proliferation and migration, and increased LAMA4 expression has been associated with adverse survival outcomes in HCC, pancreatic cancer, and gastric cancer (Huang et al., 2008; Wang et al., 2018; Zheng et al., 2020).
