Features:
Cannabidiol (CBD) is a cannabinoid compound found in cannabis plants.
Cannabidiol (CBD) is a non-psychoactive phytocannabinoid derived from Cannabis sativa that has drawn interest for its potential anticancer properties.
Pathways:
-Mitochondrial dysfunction, with loss of membrane potential leading to the release of cytochrome c and activation of caspase cascades
-Receptor-Mediated Signaling (CB Receptors and Beyond)
-Can increase reactive oxygen species (ROS)
-Can induce ER stress, which activates the unfolded protein response.
-Suppress key survival and proliferation signaling cascades such as the PI3K/Akt/mTOR pathway.
-Impair angiogenesis

Cannabidiol — Cannabidiol (CBD) is a non-intoxicating phytocannabinoid from Cannabis sativa with pleiotropic signaling effects that include ion-channel modulation, lipid-membrane stress, mitochondrial injury, oxidative stress induction, and context-dependent receptor/transcriptional effects. It is formally classified as a plant-derived cannabinoid small molecule and, clinically, as the active ingredient of the FDA-approved oral drug Epidiolex for certain seizure disorders rather than for cancer treatment. Standard abbreviations include CBD; the major acidic biosynthetic precursor is CBDA. For oncology, the evidence base is still mainly preclinical, with recurrent themes of apoptosis or autophagic death, EMT and invasion suppression, and chemo-sensitization in selected models, but translation is constrained by formulation-dependent exposure, extensive first-pass metabolism, and clinically important drug-interaction and hepatic-safety considerations.

Primary mechanisms (ranked):

  1. Mitochondrial stress with ROS increase, membrane depolarization, and intrinsic cell-death signaling.
  2. TRP-channel mediated Ca²⁺ dysregulation, especially TRPV2 or TRPV4-linked stress responses in glioma models.
  3. ER stress and integrated stress-response signaling, including ATF4–DDIT3/CHOP-associated death programs.
  4. PI3K/Akt/mTOR survival-axis suppression with secondary effects on proliferation, autophagy, and metabolic fitness.
  5. Anti-migratory and anti-metastatic signaling, including EMT reversal and Wnt/β-catenin suppression in colorectal cancer models.
  6. PPARγ-associated pro-death and anti-proliferative signaling in some tumor contexts.
  7. Ceramide-linked stress signaling in pancreatic cancer models.
  8. Chemosensitization through enhanced drug uptake or stress amplification in selected models, especially glioma.

Bioavailability / PK relevance: CBD is highly lipophilic, has low and formulation-sensitive oral bioavailability, and undergoes extensive hepatic and gut metabolism primarily via CYP2C19, CYP3A4, and UGT pathways. Food markedly changes exposure; high-fat meals can increase systemic exposure several-fold. The approved prescription formulation has a long terminal half-life after repeated dosing, but oncology studies and commercial products are heterogeneous in formulation, route, and reliability of exposure.

In-vitro vs systemic exposure relevance: This is a major translation constraint. Many anticancer in-vitro studies use low-to-moderate or higher micromolar concentrations that may not be reproducibly achievable in tumors with standard oral dosing, especially with non-pharmaceutical products. Some local-delivery, inhaled, or nanoformulation approaches may improve relevance, but for most cancer contexts the mechanistic literature still outpaces clinically validated exposure-response data.

Clinical evidence status: Preclinical evidence is substantial. Human cancer evidence is limited to small early-phase studies, supportive-care trials, and ongoing exploratory cancer trials; there is no established cancer-directed indication. Current oncology guidance supports discussing cannabis or cannabinoids for selected supportive-care scenarios but recommends against using them as anticancer therapy outside clinical trials.

-Liver injury is one of the main labeled toxicities: ALT elevations above 3× ULN occurred in 12% to 13% of treated patients in controlled studies

Mechanistic ranking

Rank Pathway / Axis Cancer Cells Normal Cells TSF Primary Effect Notes / Interpretation
1 Mitochondrial ROS and membrane injury ROS ↑; ΔΨm ↓; cytochrome c release ↑; caspase signaling ↑ ↔ or less sensitive in some models R/G Apoptosis or lethal stress Most central cross-tumor mechanism; often upstream of apoptosis and stress-pathway collapse.
2 TRPV2 or TRPV4 Ca²⁺ influx Ca²⁺ influx ↑; stress signaling ↑; drug uptake ↑ Limited effect reported in some astrocyte comparisons P/R Autophagy, apoptosis, chemosensitization Especially relevant in glioma literature; supports both direct cytotoxicity and adjunct sensitization.
3 ER stress and integrated stress response ATF4 ↑; DDIT3 CHOP ↑; UPR stress ↑ Usually weaker or not well defined R/G Death-program engagement Frequently coupled to Ca²⁺ dysregulation, ceramide changes, and mitochondrial dysfunction.
4 PI3K Akt mTOR survival signaling PI3K/Akt/mTOR ↓ ↔ (context-dependent) R/G Reduced survival and growth A common convergence node rather than always the initiating lesion.
5 Apoptosis execution program Apoptosis ↑; caspase 3 8 9 ↑; PARP cleavage ↑ ↔ or less pronounced in selected comparisons G Tumor cell loss Robust downstream phenotype across many cell systems.
6 Autophagy and mitophagy Autophagy ↑; mitophagy arrest or lethal autophagy ↑ Unclear selectivity R/G Stress adaptation failure or non-apoptotic death Can be cytotoxic or partially adaptive depending on model; important in glioma work.
7 EMT and Wnt β-catenin axis Wnt/β-catenin ↓; Snail ↓; vimentin ↓; E-cadherin ↑; metastasis programs ↓ Not established as a core normal-cell effect G Migration and invasion suppression Strong recent relevance in colorectal cancer models and consistent with the Nestronics entry.
8 PPARγ signaling PPARγ ↑ ↔ (context-dependent) R/G Pro-apoptotic transcriptional shift Mechanistically meaningful but not universal across tumor types.
9 Mitochondrial ROS increase secondary redox axis ROS ↑ Potential antioxidant or mixed effects in non-cancer settings P/R Stress amplification Include as a secondary redox axis rather than as the sole mechanism because CBD redox effects are context-dependent.
10 HIF-1α and angiogenesis signaling HIF-1α ↓; pro-angiogenic tone ↓ Not clearly established clinically G Vascular support restraint Present in preclinical literature and also reflected on the Nestronics page, but not a top translation driver.
11 Ceramide stress signaling CerS1 ↑; ceramide stress ↑ Unknown R/G ER stress linked cytotoxicity Currently most notable in pancreatic cancer work; may be subtype-specific.
12 Glycolysis and lipogenesis Lipogenesis ↓; metabolic fitness ↓ Systemic lipid effects also occur outside oncology G Metabolic disadvantage Mechanistically relevant but less mature as a core anticancer axis than stress-death signaling.
13 Chemosensitization Sensitivity to cytotoxics ↑ Potential therapeutic window depends on regimen G Adjunct leverage Most persuasive in glioma and some combination-model systems; clinically still exploratory.
14 Clinical Translation Constraint Micromolar in-vitro activity often exceeds routine systemic tumor exposure Normal-tissue PK and DDI burden remain clinically relevant G Limits standalone translation Poor and meal-sensitive oral bioavailability, product heterogeneity, hepatic injury risk, sedation, and CYP UGT interactions are major constraints.

Type:
Vimentin, a major constituent of the intermediate filament family of proteins, is ubiquitously expressed in normal mesenchymal cells and is known to maintain cellular integrity and provide resistance against stress. Vimentin is overexpressed in various epithelial cancers, including prostate cancer, gastrointestinal tumors, tumors of the central nervous system, breast cancer, malignant melanoma, and lung cancer. Vimentin’s overexpression in cancer correlates well with accelerated tumor growth, invasion, and poor prognosis; however, the role of vimentin in cancer progression remains obscure.

In many epithelial-derived tumors (carcinomas), elevated Vimentin expression is often observed in cancer cells that have undergone EMT. This upregulation is characteristic of a shift toward a mesenchymal state, which is associated with reduced cell–cell adhesion and increased motility. Vimentin expression is also noted in the tumor stroma, reflecting the presence and activation of mesenchymal cells such as cancer-associated fibroblasts (CAFs). This dual expression can contribute to the remodeling of the tumor microenvironment.
The degree of Vimentin expression may vary depending on the tumor type, grade, and stage. More aggressive and advanced tumors tend to show higher levels of Vimentin expression.

High Vimentin expression has been correlated with poor clinical outcomes in several cancers, including breast, colorectal, prostate, and lung cancers.
Elevated Vimentin levels are typically associated with higher tumor grade, increased invasiveness, enhanced metastatic potential, and a greater risk of recurrence.
As a component of the EMT signature, high Vimentin expression can serve as an indicator of a more aggressive tumor phenotype and is often associated with reduced overall survival.
- vimentin up-regulation is often used as a marker of EMT in cancer
