We queried human LRSAM1 expression in common human malignant tumors from HPA (https://www.proteinatlas.org/) (Figure 1(a)) to analyze and compare LRSAM1 expression patterns between the choriocarcinoma cell line JEG-3 and JAR and the trophoblast cell line HTR8/sev8. Here, LRSAM1 is linked to cancer.
