LAMP2 and esophageal squamous cell carcinoma: Next, heat maps were used to illustrate the top 10 genes positively correlated with LAMP2; these were LINC02457, AC005865.1, LRRC38, CNGB1, EFCAB1, KREMEN2, AC099066.2, PHF24, LAMA1, and SLC6A2. CNGB1 is involved in the olfactory pathway and has been found to be overexpressed in ESCC.
