Mapping of mTOR drug targets: Featured platforms for anti-cancer drug discovery

Raef Shams et al.

Summary: mTOR is a protein kinase involved in cell growth and proliferation, which can be assembled into mTORC1 and mTORC2 complexes with different functions. In cancer cells, mTOR is hyperactivated to adapt to stress conditions, leading to efforts in developing compounds to inhibit mTOR and disrupt cancer cell metabolism.

CircWHSC1 Promotes Breast Cancer Progression by Regulating the FASN/AMPK/mTOR Axis Through Sponging miR-195-5p

Qian Chen et al.

Summary: Studies have shown that circRNAs play a role in cancer progression. In this study, circWHSC1 was identified as a novel circRNA that accelerates ovarian cancer progression. The function of circWHSC1 in breast cancer was investigated, and it was found that circWHSC1 is up-regulated in breast cancer tissues and is associated with higher tumor stages, lymphatic metastasis, and worse survival of breast cancer patients. Functional experiments showed that circWHSC1 promotes breast cancer cell proliferation, migration, invasion, and tumor growth. Mechanistically, circWHSC1 functions as a competitive endogenous RNA by sponging miR-195-5p, which delays breast cancer progression. In addition, miR-195-5p regulates the expression of fatty acid synthase (FASN) and activates the AMPK/mTOR pathway. Inhibition of FASN or activation of the AMPK pathway reverses the oncogenic effects mediated by circWHSC1. Overall, circWHSC1 acts as an oncogene in breast cancer by modulating the miR-195-5p/FASN/AMPK/mTOR pathway.

Summary: In this study, it was found that circST3GAL6 was downregulated in gastric cancer and was associated with poor prognosis. Overexpression of circST3GAL6 inhibited malignant behaviors of gastric cancer cells, potentially through inducing apoptosis and autophagy. Furthermore, it was demonstrated that circST3GAL6 regulated gastric cancer through the miR-300/FOXP2 axis and regulated apoptosis and autophagy through FOXP2-mediated inhibition of the MET pathway.

Summary: The global cancer burden in 2020 saw an estimated 19.3 million new cancer cases and almost 10.0 million cancer deaths. Female breast cancer surpassed lung cancer as the most commonly diagnosed cancer, while lung cancer remained the leading cause of cancer death. These trends are expected to rise in 2040, with transitioning countries experiencing a larger increase compared to transitioned countries due to demographic changes and risk factors associated with globalization and a growing economy. Efforts to improve cancer prevention measures and provision of cancer care in transitioning countries will be crucial for global cancer control.

The depletion of Circ-PRKDC enhances autophagy and apoptosis in T-cell acute lymphoblastic leukemia via microRNA-653-5p/Reelin mediation of the PI3K/AKT/mTOR signaling pathway

Zhang Ling et al.

Summary: A study on the mechanisms of Circ-PRKDC and miR-653-5p/RELN axis in T-cell acute lymphoblastic leukemia (T-ALL) found that Circ-PRKDC acted as a sponge for miR-653-5p, which in turn targeted RELN, affecting cell proliferation, apoptosis, and autophagy. The interactions between Circ-PRKDC, miR-653-5p, and RELN disrupted the PI3K/AKT/mTOR signaling pathway, enhancing autophagy and apoptosis in T-ALL cells. These findings suggest potential therapeutic targets for T-ALL involving this specific RNA network.
