LINC00323 and gastric cancer: Previously studies have shown that LINC00323 overexpression might serve as a novel independent prognostic factor for survival of gastric cancer patients [25], and LINC00323 expression was associated with osteosarcoma recurrence [41], and that LINC00323 involved in the progression of breast cancer via participating in the glycosphingolipid biosynthesis pathway and the regulation of transcription and mast cell activation biological processes [42].
