Kaempferol / TumCCA Cancer Research Results

KaempF, Kaempferol: Click to Expand ⟱
Features:

Kaempferol = dietary flavonol polyphenol (aglycone; often present as glycosides such as kaempferol-3-O-glucoside). Sources: tea, kale, spinach, capers, broccoli, onions. Primary mechanisms (ranked):
1) PI3K/Akt/mTOR pathway inhibition → ↓ proliferation, ↓ survival signaling (core anti-tumor axis).
2) MAPK modulation (ERK/JNK/p38) → apoptosis or growth arrest (context-dependent).
3) NF-κB suppression → ↓ inflammatory and pro-survival transcription programs.
4) Pro-oxidant ROS induction at higher concentrations → mitochondrial apoptosis signaling.
Bioavailability/PK relevance: Oral absorption modest; extensive phase II metabolism (glucuronidation/sulfation); plasma typically low µM or sub-µM after dietary intake; many in-vitro studies use 10–100 µM (often exceeding achievable systemic exposure without specialized delivery).
Clinical evidence status: largely preclinical (cell + animal); limited human cancer trial data; strongest support in epidemiologic associations rather than interventional oncology RCTs.

Kaempferol—an abundant flavonoid found in various fruits, vegetables, and medicinal herbs—affects cancer cell behavior

Pathways:
-Inhibit the PI3K/Akt signaling
-Modulation of the MAPK pathway (including ERK1/2)
-Inhibit NF-κB Signaling Pathway
-can upregulate or activate p53-dependent pathways
-Inhibitory action on STAT
-Activation of AMPK
-Reduce VEGF
-Can induce oxidative stress in cancer cells (ROS)

Kaempferol — Cancer vs Normal Pathway Effects

Rank Pathway / Axis Cancer Cells (↑ / ↓ / ↔) Normal Cells (↑ / ↓ / ↔) TSF Primary Effect Notes / Interpretation
1 PI3K/Akt/mTOR ↓ proliferation; ↓ survival signaling ↔ / mild ↓ (cytoprotective context) R→G Growth suppression Core mechanistic axis across multiple tumor models (breast, lung, colon, prostate).
2 MAPK (ERK, JNK, p38) ↑ JNK/p38 (pro-apoptotic); ↓ ERK (proliferative) ↔ (dose-dependent) R Apoptosis induction Often stress-activated signaling; balance of ERK vs JNK determines outcome.
3 NF-κB ↓ transcription of inflammatory & anti-apoptotic genes ↓ inflammatory tone R→G Anti-inflammatory / anti-survival Reduces cytokine signaling and tumor microenvironment support pathways.
4 ROS ↑ (high concentration; pro-oxidant apoptosis) ↔ / ↓ (antioxidant at low conc.) P→R Mitochondrial stress Biphasic: antioxidant at dietary levels; pro-oxidant at higher in-vitro doses.
5 NRF2 ↔ / ↓ (context-dependent) ↑ cytoprotective response G Redox adaptation May activate antioxidant genes in normal cells; persistent activation in tumors could support resistance.
6 Intrinsic apoptosis (Bax/Bcl-2, caspases) ↑ Bax; ↓ Bcl-2; ↑ caspase-3/9 ↔ R→G Mitochondrial apoptosis Common downstream convergence of ROS + PI3K suppression.
7 Ca2+ signaling ↑ mitochondrial Ca2+ (subset models) ↔ R Apoptotic amplification Not universal; observed in certain carcinoma lines.
8 HIF-1α / Angiogenesis ↓ HIF-1α; ↓ VEGF (model-dependent) ↔ G Anti-angiogenic potential Observed in hypoxia models; translational impact uncertain.
9 Ferroptosis ↔ (indirect; limited data) ↔ R Redox-linked sensitivity (theoretical) No consistent ferroptosis signature established.
10 Clinical Translation Constraint Low oral bioavailability; rapid conjugation; in-vitro concentrations commonly exceed systemic exposure; limited human interventional oncology data. — PK / Evidence Dietary intake likely below cytotoxic range; delivery systems (nano-formulations) under investigation.

Type:
Tumor cell cycle arrest refers to the process by which cancer cells stop progressing through the cell cycle, which is the series of phases that a cell goes through to divide and replicate. This arrest can occur at various checkpoints in the cell cycle, including the G1, S, G2, and M phases. S, G1, G2, and M are the four phases of mitosis.
