We have also demonstrated that SEMA5A has a constitutive expression in PC cell lines derived from metastatic sites in comparison with low endogenous expression in the primary tumor-derived cell line.
We utilized human tissue microarrays and different PC mouse models (Pdx1-cre; LSL- Kras<sup>(G12D)</sup>, Pdx1-Cre; LSL-Kras<sup>(G12D)</sup>; LSL-p53<sup>(R172H)</sup> and RIP1-Tag2) to analyze SEMA5A expression during PC progression.
Our earlier reports demonstrated that membrane-bound semaphorin 5A (SEMA5A) is expressed in aggressive pancreatic cancer cells and tumours, and promotes tumour growth and metastasis.
