CLPTM1L/CRR9 ectodomain interaction with GRP78 at the cell surface signals for survival and chemoresistance upon ER stress in pancreatic adenocarcinoma cells

Abstract: Altered regulation of endoplasmic reticulum (ER) homeostasis has been implicated in many cancers and has recently become a therapeutic and chemosensitization target of interest. We have identified Cleft Lip and Palate Transmembrane 1-Like (CLPTM1L)/Cisplatin Resistance Related Protein 9 (CRR9) as an ER stress related mediator of cytoprotection in pancreatic cancer. We recently demonstrated that CLPTM1L is highly expressed in pancreatic ductal adenocarcinoma and associated with poor outcome. Furthermore, we hav… Show more

“…The top four biomarkers for NAC resistance, namely, GRP78, CADM1, PGES2, and RUXF demonstrated very high predictive ability for chemo-resistance with AUROC > 0.92. Notably, GRP78 has been previously demonstrated to play an important role in mediating chemoresistance in PDAC (15)(16)(17). Moreover, RUXF and PGES2 are known to be involved in chemo-resistance in ovarian and colorectal cancer, respectively (18,19).…”

“…Alternatively, the proapoptotic action of the UPR could be compensated by the activation of the Akt/PI3K pathway, resulting in cell survival. The extracellular loop of Cleft Lip and Palate Transmembrane 1-Like (CLPTM1L) is essential for gemcitabine resistance and interaction with GRP78 [ 51 ]. Additionally, natural products such as isoliquiritigenin, a chalcone-type flavonoid, were able to reduce the chemoresistance and colony-forming ability of oral squamous cell carcinomas [ 52 ].…”

“…With the development of research and technology, it is believed that GRP78 may have obvious therapeutic potential as a target (55,56). Both GRP78 itself and other forms of GRP78 have a unique role in controlling cell survival and signal transduction, which is developing into an excellent treatment tool for malignant tumors in the targeted treatment of some cancers, and is expected to be applied to other diseases.…”
