Thirty GBC patients were classified into two groups depending on their Malat1 levels in tumor tissues relative to the median ratio (3.31): high-Malat1 group (n = 15, Malat1 expression ratio ≥ median ratio); and low-Malat1 group (n = 15, Malat1 expression ratio < median ratio). Here, MALAT1 is linked to neoplasm.
