AMPK activation and Ubiquitin Proteasome System (UPS) inhibition have gained great attention as therapeutic strategies for the treatment of certain types of cancers. While AMPK serves as a master regulator of cellular metabolism, UPS regulates protein homeostasis. Although the crosstalk between them is suggested, the relationship between these two important pathways is not very clear. We observed that proteasome inhibition leads to AMPK activation in human breast cancer cells. We report that a variety of proteasome inhibitors activate AMPK in all of the tested cancer cell lines. Our data using Liver Kinase B1 (LKB1)-deficient cancer cells suggests that proteasome inhibitor-induced …

New drug discoveries and new approaches towards diagnosis and treatment have improved cancer therapeutics remarkably. One of the most influential and effective discoveries in the field of cancer therapeutics was antimetabolites, such as the antifolates. The interest in antifolates increased as some of the antifolates showed responses in cancers, such as mesothelioma, leukemia, and breast cancers. When pemetrexed (PTX) was discovered, our laboratory had established that the primary mechanism of action of pemetrexed is to inhibit thymidylate 22 synthase (TS) (E. Taylor et al., 1992). Preclinical studies have shown that PTX has a broad range of antitumor activity in human …
