Mining gastric cancer cellular quantitative proteomics data to analyse the proteome change upon CAMKK2 inhibition


ABSTRACT: Gastric cancer is a global health concern. Molecular alterations in various signaling pathways have been implicated in the development and late-stage progression/metastasis of gastric cancer. Reports have suggested that Wnt signaling pathway might contribute to gastric carcinogenesis by stimulating migration and invasion of gastric cancer cells. This study aimed at analysing the proteome change upon CAMKK2 inhibition in gastric cancer cells using LC-MS/MS based quantitative proteomic approach. A TMT based quantitative approach was used to identify the significantly altered proteins upon CAMKK2 inhibition. Gene Ontology (GO) analysis and pathway analysis was done for the significantly altered proteins and was later validated by immunoblotting.

Gastric cancer is the fifth most common cancer and the third leading cause of cancer-related death worldwide. We showed previously that calcium/calmodulin-dependent protein kinase kinase 2 (CAMKK2), a serine-threonine kinase, is highly expressed in gastric cancer and leads to progression. In the present study, we identified the molecular networks involved in CAMKK2-mediated progression of gastric adenocarcinoma. Treatment of gastric cancer cell lines with a CAMKK2 inhibitor, STO-609, resulted in  ...[more]
