Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance Ref
1 Wnt / β-catenin signaling ↓ Wnt/β-catenin (↓ β-catenin nuclear program) Growth & stemness suppression Piperine suppresses canonical Wnt signaling and shows anti-cancer effects in colorectal cancer cells (ref)
2 PI3K → AKT survival signaling ↓ PI3K/AKT signaling Reduced survival / increased apoptosis Gastric cancer study concludes piperine inhibits proliferation and induces apoptosis through inhibition of PI3K/Akt signaling (ref)
3 AKT → mTOR axis ↓ Akt/mTOR Anti-growth + anti-migration Piperine downregulates Akt/mTOR signaling with associated inhibition of migration and MMP-9 expression (ref)
4 NF-κB transcriptional program ↓ NF-κB activation Reduced inflammatory / pro-survival gene expression Piperine is reported as a potent inhibitor of NF-κB and related transcription factor activity in melanoma cells (ref)
5 STAT3 → Snail EMT axis ↓ STAT3 / ↓ Snail → ↓ EMT Anti-migration / anti-invasion Piperine inhibits colorectal cancer migration/invasion through a STAT3/Snail-mediated EMT mechanism (ref)
6 Multidrug resistance transporter ABCB1 (P-gp) ↓ P-gp-mediated efflux (chemosensitization) Improved chemo response (MDR reversal) Demonstrates piperine has chemosensitizing activity in P-gp–mediated MDR models (piperine characterized as P-gp substrate/modulator) (ref)
7 ROS / oxidative stress ↑ ROS Upstream stress trigger Piperine induces oxidative stress in cancer cells (ROS increase shown) and links it to growth inhibition/apoptosis (ref)
8 Intrinsic apoptosis (caspase activation) ↑ apoptosis Programmed cell death HeLa study: piperine induces apoptosis in a dose-dependent manner with apoptosis markers reported (ref)
9 Autophagy-dependent cell death (ROS–Akt/mTOR coupling) ↑ autophagy-dependent death (with ↓ Akt/mTOR) Stress-lethal program Colon cancer study: piperine induces autophagy-dependent cell death by increasing ROS and inhibiting Akt/mTOR signaling (ref)
10 Cell-cycle progression ↑ cell-cycle arrest (context-dependent) Proliferation blockade Rectal cancer cell study: piperine impairs cell-cycle progression and produces cytostatic/cytotoxic effects (ref)
11 Migration / invasion (MMP-9 axis) ↓ migration / ↓ MMP-9 Anti-metastatic phenotype Piperine suppresses migration with MMP-9 downregulation and Akt/mTOR inhibition (ref)
12 In vivo chemosensitization (doxorubicin) ↑ doxorubicin sensitivity Enhanced therapeutic efficacy Study evaluates piperine as an adjuvant to enhance doxorubicin sensitivity in triple-negative breast cancer models (ref)

Type:
Pyruvate is a small organic molecule that is a key intermediate in several metabolic pathways.
It is the end product of glycolysis, a process that breaks down glucose to release energy.

Increased conversion of pyruvate to lactate (via lactate dehydrogenase, LDH) contributes to the acidification of the tumor microenvironment, which can promote tumor invasion and immune evasion.

Cancer cells can dynamically adjust pyruvate utilization based on nutrient availability. Under certain conditions, some cancer cells may reroute pyruvate to the mitochondria for oxidative phosphorylation, especially in nutrient- or oxygen-rich environments.

This flexibility also means that targeting pyruvate metabolism (e.g., by inhibiting key enzymes like PKM2 or PDKs) is an area of interest in cancer therapy.

Pyruvate is a central metabolite whose handling in cancer cells is redirected to favor increased glycolysis and lactate production over oxidative phosphorylation. This metabolic reprogramming is a key driver of tumor cell survival, proliferation, and adaptation to stress, and is associated with poor prognosis in multiple cancer types. Although not “expressed” like a protein, the regulation of pyruvate metabolism is clearly protumorigenic by sustaining the energetic and biosynthetic demands of cancer, and is an area of active therapeutic exploration.
