Single‐Cell Reveal GALNT7‐Dependent Ferroptosis Suppression as a Mechanism of Immunotherapy Resistance in Non‐Small Cell Lung Cancer

Advanced Science, EarlyView.
Integrated clinical and mechanistic analyses identify GALNT7 as a ferroptosis‐suppressive regulator associated with immunotherapy resistance in non‐small cell lung cancer. GALNT7 depletion promotes lipid peroxidation, mitochondrial dysfunction, and ferroptosis, enhances CD8+ T‐cell activation and IFN‐γ production, and sensitizes tumors to PD‐1 blockade,

The Deubiquitylase OTUB1 Mediates Ferroptosis via Stabilization of SLC7A11 [PDF]

Cancer Research, 2019
Abstract Although cell-cycle arrest, senescence, and apoptosis are established mechanisms of tumor suppression, accumulating evidence reveals that ferroptosis, an iron-dependent, nonapoptotic form of cell death, represents a new regulatory pathway in suppressing tumor development.

TRIM21 accelerates ferroptosis in intervertebral disc degeneration by promoting SLC7A11 ubiquitination and degradation

Open Life Sciences
Intervertebral disc degeneration (IVDD) is a common cause of chronic low back pain, and ferroptosis – an iron-dependent form of cell death – has been linked to oxidative stress-induced damage in nucleus pulposus cells (NPCs).

RBM12 Maintains Glioma Stem Cells by Activating Amino Acid‐Dependent mTORC1 Signaling via SLC7A5 mRNA Stabilization

Advanced Science, EarlyView.
This study shows that in glioma stem cells (GSCs), RBM12 recruits ALKBH5 to remove m6A from SLC7A5 transcripts, thereby enhancing mRNA stability, which elevates large neutral amino acid (LNAA) levels and activates mTORC1, promoting GSC proliferation, self‐renewal, and tumor growth.

Differential expression of SLC7A11 in colorectal cancer.

, 2023
Cancer is a leading cause of death and colorectal cancer is among the most lethal cancers (1, 2). We mined published microarray datasets (3, 4) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with colorectal cancer (CRC). We found significant differential

SLC7A11 expression level dictates differential responses to oxidative stress in cancer cells

Nature Communications, 2023
The cystine transporter solute carrier family 7 member 11 (SLC7A11; also called xCT) protects cancer cells from oxidative stress and is overexpressed in many cancers. Here we report a surprising finding that, whereas moderate overexpression of SLC7A11 is

REGγ Suppresses Ferroptosis and Induces Drug Resistance by Degrading WDR6 in Chondrosarcoma

Advanced Science, EarlyView.
Here, we identified REGγ as a susceptibility factor in chondrosarcoma. Our study demonstrates that abnormally activated REGγ‐20S proteasome promotes chondrosarcoma development and progression. Further validation in animal models revealed that blocking REGγ function induced ferroptosis, suppressed malignant progression of chondrosarcoma, and uncovered a
