Methylglyoxal / selectivity Cancer Research Results

MGO, Methylglyoxal: Click to Expand ⟱
Features:
Methylglyoxal is a reduced derivative of pyruvic acid that is produced by glycolysis and other metabolic pathways. It is involved in the formation of advanced glycation end products, DNA damage, and diabetes complications.

-Methylglyoxal is specifically inhibits OXPHOS in cancer cells ?
-Methylglyoxal in cancer cells inhibits GAPDH, an essential enzyme acting in the glycolsis pathway. GAPDH inhibition depletes ATP profoundly depriving the cancer cells of energy.
-Activator of GABA A receptor

Some research may indicate it can promote cancer growth.

Dose: (30-40mg/day) 7.5mg/kg 4 times/day (plus 400mg Vit C) + VitB complex twice/day
-Combine with curcumin(8g/d)?

Combine with:
Chitosan?
Creatine (30-60 mins before)
GLO1 inhibitors (Naringin, Curcumin)
Nrf2 inhibitors: (ex Ascorbic Acid)
GABA supplementation
Metformin?

Avoid combination with DCA?

Pathways
1. Glyoxalase System Glyoxalase I and II: (glyoxalase system) which detoxifies methylglyoxal. In many cancers, the expression of glyoxalase I (and sometimes glyoxalase II) is upregulated. This allows tumor cells to tolerate higher MG levels resulting from their altered metabolism (often enhanced glycolysis), protecting them from dicarbonyl stress while simultaneously supporting their survival and proliferation.

2. Advanced Glycation End Products (AGEs) and RAGE Pathway
AGE Formation:-Supplemented MG can increase the formation of advanced glycation end products (AGEs) RAGE Activation:AGEs can lead to the activation of RAGEE, which include the activation of NF-κB and MAPK pathways.

3. NF-κB Signaling Pathway: The activation of NF-κB by MG-induced AGE-RAGE signaling

4. MAPK Pathway: can be activated as a result of MG-induced oxidative and dicarbonyl stress
.
5. ROS Generation and Oxidative Stress
Methylglyoxal can raise intracellular ROS levels. (reinforcing the pro-tumorigenic environment.) -excessive ROS can be deleterious.

Type:
The selectivity of cancer products (such as chemotherapeutic agents, targeted therapies, immunotherapies, and novel cancer drugs) refers to their ability to affect cancer cells preferentially over normal, healthy cells. High selectivity is important because it can lead to better patient outcomes by reducing side effects and minimizing damage to normal tissues.

Achieving high selectivity in cancer treatment is crucial for improving patient outcomes. It relies on pinpointing molecular differences between cancerous and normal cells, designing drugs or delivery systems that exploit these differences, and overcoming intrinsic challenges like tumor heterogeneity and resistance

Factors that affect selectivity:
1. Ability of Cancer cells to preferentially absorb a product/drug
-EPR-enhanced permeability and retention of cancer cells
-nanoparticle formations/carriers may target cancer cells over normal cells
-Liposomal formations. Also negatively/positively charged affects absorbtion

2. Product/drug effect may be different for normal vs cancer cells
- hypoxia
- transition metal content levels (iron/copper) change probability of fenton reaction.
- pH levels
- antiOxidant levels and defense levels

3. Bio-availability
