Relationship of mTORC1 and ferroptosis in tumors

Discover Oncology
AbstractFerroptosis is a novel form of programmed death, dependent on iron ions and oxidative stress, with a predominant intracellular form of lipid peroxidation. In recent years, ferroptosis has gained more and more interest of people in the treatment mechanism of targeted tumors.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

Advanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Hydrogel‐Mediated Preservation of Live Tumor Explants for Drug Development in Peritoneal Metastases

Advanced Materials, EarlyView.
This study presents a hyaluronan‐based hydrogel platform preserving the native tumor microenvironment (morphology, tissue composition, histology) of patient‐derived explants from peritoneal metastases, enabling clinically relevant drug screening. Hydrogel properties such as stiffness and degradation are crucial for longer‐term histoculture.

mTORC1 Signaling Is Palmitoylation-Dependent in Hippocampal Neurons and Non-neuronal Cells and Involves Dynamic Palmitoylation of LAMTOR1 and mTOR

Frontiers in Cellular Neuroscience, 2019
The mechanistic target of rapamycin (mTOR) Complex 1 (mTORC1) controls growth and proliferation of non-neuronal cells, while during neuronal development mTORC1 responds to glutamate and neurotrophins to promote neuronal migration and dendritic ...

An mTORC1 to HRI signaling axis promotes cytotoxicity of proteasome inhibitors in multiple myeloma

Cell Death and Disease, 2022
Multiple myeloma (MM) causes approximately 20% of deaths from blood cancers. Notwithstanding significant therapeutic progress, such as with proteasome inhibitors (PIs), MM remains incurable due to the development of resistance.

Nanoinjection Platform for Drug Delivery in Breast Cancer Therapeutics

Advanced Materials Interfaces, EarlyView.
A schematic shows Nanoarchaeosomes loaded with doxorubicin (NAD) delivered via silicon nanotubes (SiNTs) into MCF‐7 cells, triggering apoptosis and necrosis. Released doxorubicin generates ROS, disrupts mitochondria, and intercalates DNA. This dual‐action nanoinjection enhances cytotoxicity and improves breast cancer therapy efficacy.

Escaping mTOR inhibition for cancer therapy: Tumor suppressor functions of mTOR

Molecular & Cellular Oncology, 2017
A master promoter of cell growth, mammalian target of rapamycin (mTOR) is upregulated in a large percentage of cancer cells. Still, targeting mTOR using rapamycin has a limited outcome in patients. Our recent results highlight the additional role of mTOR

RNA m6A methyltransferase METTL3 facilitates colorectal cancer by activating m6A-GLUT1-mTORC1 axis and is a therapeutic target.

Gastroenterology, 2020
BACKGROUND & AIMS RNA N6-methyladenosine (m6A) modification has recently emerged as a new regulatory mechanism in cancer progression. We aimed to explore the role of m6A regulatory enzyme METTL3 in colorectal cancer (CRC) pathogenesis and its potential ...
