Insights

Disrupting glucose metabolism via glucose dyshomeostasis triggers multiple cell death types, including disulfidptosis, cuproptosis, and ferroptosis. This approach enhances ovarian tumor therapy by targeting the SLC7A11/GSH/GPX4 antioxidant axis.

Area of Science:

  • Biomedical Engineering
  • Oncology
  • Metabolic Therapy

Background:

  • Glucose dyshomeostasis is a key target in tumor metabolic therapy, potentially overcoming resistance to regulated cell deaths (RCDs).
  • The precise pathways linking glucose metabolism disruption to RCDs and their therapeutic applications require further elucidation.
  • The SLC7A11/GSH/GPX4 antioxidant axis is implicated in cellular responses to metabolic stress.

Purpose of the Study:

  • To investigate how glucose dyshomeostasis impacts the SLC7A11/GSH/GPX4 antioxidant axis.
  • To explore the potential of simultaneously inducing disulfidptosis, cuproptosis, and ferroptosis through glucose dyshomeostasis.
  • To evaluate the therapeutic efficacy of a novel nanoshuttle system in ovarian tumor models.

Main Methods:

  • Utilized glucose oxidase (GOx)-modified copper-apigenin (CuAp) network nanoshuttles (CuAp@GOx NSs) to induce glucose dyshomeostasis.
  • Inhibited glucose transporter 1 (GLUT1) and consumed glucose to achieve dyshomeostasis.
  • Assessed the impact on NADPH levels, the SLC7A11/GSH/GPX4 axis, and subsequent RCD induction.

Main Results:

  • Glucose dyshomeostasis downregulated NADPH, disrupting the SLC7A11/GSH/GPX4 antioxidant axis.
  • Simultaneous induction of disulfidptosis (via cystine accumulation), cuproptosis (via GSH-mediated copper inactivation), and ferroptosis (via GPX4 downregulation) was achieved.
  • CuAp@GOx NSs demonstrated significant efficacy in an ovarian tumor model due to the combined RCD effects.

Conclusions:

  • Glucose dyshomeostasis effectively targets the SLC7A11/GSH/GPX4 axis to induce multiple RCDs.
  • CuAp@GOx NSs offer a promising therapeutic strategy for ovarian cancer by combining disulfidptosis, cuproptosis, and ferroptosis.
  • This study presents a novel approach for tumor therapy centered on manipulating glucose metabolism and RCD pathways.

Glucose Transporters

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Secondary Active Transport01:55

Secondary Active Transport

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Glucose Homeostasis: Regulation of Blood Glucose01:02

Glucose Homeostasis: Regulation of Blood Glucose

Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

pH Regulation in Cells01:28

pH Regulation in Cells

pH plays a critical role in maintaining normal cellular activities. It helps maintain the structure and function of various proteins, dictates the charge on cellular membranes, and is crucial for metabolic reactions inside the cell. Moreover, cells use the energy from the proton motive force to generate ATP.
Cytosolic pH
Under physiological conditions, the cytosolic pH is slightly more acidic than the extracellular pH. However, cells must prevent further acidification of their cytosol to...

Export of Misfolded Proteins out of the ER01:32

Export of Misfolded Proteins out of the ER

After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...
