Crocetin / CREB Cancer Research Results

Cro, Crocetin: Click to Expand ⟱

Features:

Crocetin is a carotenoid pigment found in saffron (Crocus sativus) and has been studied for its potential anti-cancer properties. Research has shown that crocetin may have anti-tumor and anti-proliferative effects, inhibiting the growth of various types of cancer cells.
Crocetin is a carotenoid dicarboxylic acid derived from saffron (Crocus sativus) and is a metabolite of crocin. It is lipophilic and more bioavailable than crocin. In cancer research, crocetin is studied mainly in preclinical models, where it appears to influence apoptosis, inflammation, angiogenesis, and redox signaling. It is not a primary cytotoxic chemotherapeutic, but a signaling and stress-modulating compound.

Mechanistic themes reported:
-NF-κB suppression
-PI3K/AKT pathway modulation
-MAPK signaling effects
-Apoptosis induction (mitochondrial pathway)
-Anti-angiogenic signaling (VEGF reduction)
-Redox modulation (context-dependent antioxidant / pro-oxidant behavior)

Evidence level: predominantly cell culture and animal models.

Reported to modulate glycolytic metabolism and lactate production (model-dependent); not established as a direct LDH enzymatic inhibitor

Crocetin (Cro) — Cancer-Oriented Time-Scale Flagged Pathway Table

Rank	Pathway / Axis	Cancer / Tumor Context	Normal Tissue Context	TSF	Primary Effect	Notes / Interpretation
1	Intrinsic apoptosis (mitochondrial pathway)	Bax ↑; Bcl-2 ↓; caspases ↑ (reported)	↔ (less activation)	G	Cell death signaling	Apoptosis induction via mitochondrial membrane disruption is one of the most frequently reported tumor effects.
2	NF-κB inflammatory signaling	NF-κB ↓; cytokines/COX-2 ↓ (reported)	Inflammation tone ↓	R, G	Anti-inflammatory modulation	Reduction of inflammatory transcription may contribute to anti-proliferative and anti-invasive effects.
3	PI3K / AKT survival pathway	AKT phosphorylation ↓ (reported; model-dependent)	↔	R, G	Growth suppression	Observed in several tumor cell systems; should be presented as context-dependent.
4	MAPK signaling (ERK / JNK / p38)	Stress MAPK modulation (variable direction)	↔	P, R, G	Signal reprogramming	JNK activation and ERK suppression have been reported in some models; effects vary by cell type.
5	ROS / redox modulation	ROS ↑ (pro-apoptotic) or ROS ↓ (antioxidant) depending on dose	Oxidative stress ↓ (protective models)	P, R, G	Redox modulation (biphasic)	Crocetin can behave as antioxidant in normal cells and pro-oxidant in tumor contexts at higher concentrations.
6	Cell-cycle arrest	G0/G1 or G2/M arrest ↑ (reported)	↔	G	Cytostasis	Often secondary to survival pathway suppression and stress signaling.
7	Angiogenesis signaling (VEGF)	VEGF ↓; angiogenic signaling ↓ (reported)	↔	G	Anti-angiogenic support	Observed in some in vitro and animal tumor models; typically secondary to NF-κB/AKT changes.
8	Metabolic reprogramming (glycolysis tone)	Lactate ↓ (reported; indirect)	↔	R, G	Warburg modulation (indirect)	No strong evidence for direct LDH enzyme inhibition; effects likely secondary to survival/redox signaling changes.
9	Migration / invasion (MMPs)	MMP2/MMP9 ↓; invasion ↓ (reported)	↔	G	Anti-invasive phenotype	Reported reduction in metastasis markers in certain systems.
10	Chemo-sensitization (adjunct potential)	Therapy sensitivity ↑ (reported in some combinations)	Normal tissue protection possible	G	Adjunct modulation	May enhance cytotoxic response in some models; data are preclinical.
11	Translation constraint	Clinical anti-cancer efficacy not established	Generally well tolerated in dietary contexts	—	Evidence limitation	Human oncology data are limited; dosing and bioavailability remain practical considerations.

Time-Scale Flag (TSF): P / R / G

P: 0–30 min (early redox and signaling interactions)
R: 30 min–3 hr (NF-κB / PI3K / MAPK modulation)
G: >3 hr (apoptosis, angiogenesis, and phenotype-level outcomes)

CREB, cAMP Response Element Binding Protein: Click to Expand ⟱

Source:

Type: transcription factor

CREB is a transcription factor that binds to specific DNA sequences, known as cAMP response elements (CRE), in the promoter regions of target genes.
CREB is activated by phosphorylation, which allows it to bind to CRE and recruit other transcriptional coactivators.
CREB regulates the expression of genes involved in various cellular processes, including:
    Cell growth and differentiation
    Apoptosis
    Metabolism
    Neurotransmission

CREB is also involved in the regulation of genes involved in cancer, including:
    Cell cycle progression
    Angiogenesis
    Invasion and metastasis

CREB is often overexpressed in cancer tissues.
High levels of CREB expression are associated with poor prognosis, increased tumor aggressiveness, and resistance to therapy. CREB can promote the expression of genes involved in cell survival and proliferation.
