Upregulation of CD151 is found in many tumour types and CD151 overexpression was associated with poor prognosis in non-small cell lung (Tokuhara et al, 2001), colon cancer (Hashida et al, 2003), hepatocellular (Ke et al, 2009), pancreatic (Zhu et al, 2011), oesophageal (Suzuki et al, 2010), and endometrial cancer (Voss et al, 2011). Here, CD151 is linked to endometrial cancer.
