Features:
Honokiol is a Lignan isolated from bark, seed cones and leaves of trees of Magnolia species. Honokiol was traditionally used for anxiety and stroke treatment, as well as the alleviation of flu symptoms.
-considered to have antioxidant properties
-low oral bioavailability and difficulty in intravenous administration
-the development of various formulations of honokiol, including microemulsion, liposomes, nanoparticles and micelle copolymers have successfully solved the problem of low water solubility.

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 Mitochondrial integrity / intrinsic apoptosis ↓ ΔΨm; ↑ cytochrome-c release; ↑ caspases ↔ largely preserved Driver Mitochondria-directed cytotoxicity Honokiol directly accumulates in mitochondria and initiates intrinsic apoptosis in cancer cells
2 Reactive oxygen species (ROS) ↑ ROS (secondary, stress-amplifying) ↔ buffered Secondary Mitochondrial stress amplification ROS elevation follows mitochondrial perturbation rather than acting as the initiating trigger
3 STAT3 signaling ↓ STAT3 activation ↔ minimal Driver Loss of survival and stemness signaling STAT3 suppression contributes to apoptosis, CSC targeting, and reduced proliferation
4 PI3K → AKT → mTOR axis ↓ AKT / ↓ mTOR ↔ adaptive suppression Secondary Growth and anabolic inhibition AKT/mTOR inhibition reinforces mitochondrial and apoptotic stress
5 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Secondary Suppression of survival transcription NF-κB inhibition contributes to chemosensitization and anti-inflammatory effects
6 Cell cycle regulation ↑ G0/G1 or G2/M arrest ↔ spared Phenotypic Cytostatic growth control Cell-cycle arrest reflects upstream signaling disruption
7 Autophagy ↑ autophagy (context-dependent) ↑ adaptive autophagy Adaptive Stress response vs death cooperation Autophagy may precede apoptosis or act as a transient survival response


Ca+2, Calcium Ion Ca+2: Click to Expand ⟱

Type:
In all eukaryotic cells, intracellular Ca2+ levels are maintained at low resting concentrations (approximately 100 nM) by the activity of the major Ca2+ extrusion system, the plasma membrane Ca2+-ATPase (PMCA), which exchanges extracellular protons (H+) for cytosolic Ca2+.
Indeed, sustained elevation of [Ca2+]C in the form of overload, saturating all Ca2+-dependent effectors, prolonged decrease in [Ca2+]ER, causing ER stress response, and high [Ca2+]M, inducing mitochondrial permeability transition (MPT), are considered to be pro-death factors.
In cancer the Ca2+-handling toolkit undergoes profound remodelling (figure 1) to favour activation of Ca2+-dependent transcription factors, such as the nuclear factor of activated T cells (NFAT), c-Myc, c-Jun, c-Fos that promote hypertrophic growth via induction of the expression of the G1 and G1/S phase transition cyclins (D and E) and associated cyclin-dependent kinases (CDK4 and CDK2).
Thus, cancer cells may evade apoptosis through decreasing calcium influx into the cytoplasm. This can be achieved by either downregulation of the expression of plasma membrane Ca2+-permeable ion channels or by reducing the effectiveness of the signalling pathways that activate these channels. Such protective measures would largely diminish the possibility of Ca2+ overload in response to pro-apoptotic stimuli, thereby impairing the effectiveness of mitochondrial and cytoplasmic apoptotic pathways.
Voltage-Gated Calcium Channels (VGCCs): Overexpression of VGCCs has been associated with increased tumor growth and metastasis in various cancers, including breast and prostate cancer.
Store-Operated Calcium Entry (SOCE): SOCE mechanisms, such as STIM1 and ORAI1, are often upregulated in cancer cells, contributing to enhanced cell survival and proliferation.
High intracellular calcium levels are associated with increased cell proliferation and migration, leading to a poorer prognosis. Calcium signaling can also influence hormone receptor status, affecting treatment responses.
Increased Ca²⁺ signaling is associated with advanced disease and metastasis. Patients with higher CaSR expression may have a worse prognosis due to enhanced tumor growth and resistance to apoptosis. -Ca2+ is an important regulator of the electric charge distribution of bio-membranes.
