TKT, transketolase: Click to Expand ⟱
Source:
Type:
Transketolase is a key enzyme in the non-oxidative arm of the pentose phosphate pathway (PPP), and alterations in its expression or activity can affect cellular metabolism, redox balance, and biosynthetic processes that are critical for rapidly proliferating cancer cells.

– Role: TKT catalyzes the reversible transfer of two-carbon units between sugars in the non-oxidative PPP.
– Impact: By contributing to the generation of ribose-5-phosphate for nucleotide synthesis and influencing the production of NADPH, TKT activity supports both biosynthetic demands and antioxidative defense in tumor cells.
-Alterations in TKT expression can therefore impact the balance between ROS generation and detoxification, influencing cell survival and chemoresistance.
-Inhibition of TKT may thus impair the cell’s antioxidative defenses, leading to a buildup of ROS. Elevated ROS can contribute to oxidative stress, damage cellular components, and in some contexts, even promote cell death.

– Many studies have observed that TKT is upregulated in various malignancies, including lung, breast, colon, and liver cancers.
– Association with Aggressiveness: Elevated TKT expression is often correlated with higher proliferation rates, enhanced anabolic activity, and worse clinical outcomes in some cancer types.

- Review, Var, NA
Glycolysis↓, Resveratrol reduces glucose uptake and glycolysis by affecting Glut1, PFK1, HIF-1α, ROS, PDH, and the CamKKB/AMPK pathway.
GLUT1↓, resveratrol reduces glycolytic flux and Glut1 expression by targeting ROS-mediated HIF-1α activation in Lewis lung carcinoma tumor-bearing mice
PFK1↓,
Hif1a↓, Resveratrol specifically suppresses the nuclear β-catenin protein by inhibiting HIF-1α
ROS↑, Resveratrol increases ROS production
PDH↑, leading to increased PDH activity, inhibiting HK and PFK, and downregulating PKM2 activity
AMPK↑, esveratrol elevated NAD+/NADH, subsequently activated Sirt1, and in turn activated the AMP-activated kinase (AMPK),
TumCG↓, inhibits cell growth, invasion, and proliferation by targeting NF-kB, Sirt1, Sirt3, LDH, PI-3K, mTOR, PKM2, R5P, G6PD, TKT, talin, and PGAM.
TumCI↓,
TumCP↓,
p‑NF-kB↓, suppressing NF-κB phosphorylation
SIRT1↑, Resveratrol activates the target subcellular histone deacetylase Sirt1 in various human tissues, including tumors
SIRT3↑,
LDH↓, decreases glycolytic enzymes (pyruvate kinase and LDH) in Caco2 and HCT-116 cells
PI3K↓, Resveratrol also targets “classical” tumor-promoting pathways, such as PI3K/Akt, STAT3/5, and MAPK, which support glycolysis
mTOR↓, AMPK activation further inhibits the mTOR pathway
PKM2↓, inhibiting HK and PFK, and downregulating PKM2 activity
R5P↝,
G6PD↓, G6PDH knockdown significantly reduced cell proliferation
TKT↝,
talin↓, induces apoptosis by targeting the pentose phosphate and talin-FAK signaling pathways
HK2↓, Resveratrol downregulates glucose metabolism, mainly by inhibiting HK2;
GRP78/BiP↑, resveratrol stimulates GRP-78, and decreases glucose uptake,
GlucoseCon↓,
ER Stress↑, resveratrol-induced ER-stress leads to apoptosis of CRC cells
Warburg↓, Resveratrol reverses the Warburg effect
PFK↓, leading to increased PDH activity, inhibiting HK and PFK, and downregulating PKM2 activity
