Rosmarinic acid / Cyt‑c Cancer Research Results

RosA, Rosmarinic acid: Click to Expand ⟱
Features: polyphenol
Polyphenol of many herbs - rosemary, perilla, sage mint and basil. Rosmarinic acid (RA) is predominantly found in a variety of medicinal and culinary herbs, especially those belonging to the Lamiaceae family, including rosemary (Rosmarinus officinalis), basil (Ocimum basilicum), sage (Salvia officinalis), thyme (Thymus vulgaris), and mints (Mentha spp.). In addition to the Lamiaceae family, RA is also present in plants from other families, such as Boraginaceae and Apiaceae.
-Rosmarinic acid is one of the hydroxycinnamic acids, and was initially isolated and purified from the extract of rosemary, a member of mint family (Lamiaceae)
-Its chemical structure allows it to act as a free radical scavenger by donating hydrogen atoms to stabilize ROS and free radicals.
RA’s dual nature as both a phenolic acid and a flavonoid-related compound enables it to chelate metal ions and prevent the formation of free radicals, thus interrupting oxidative chain reactions. It can modulate the activity of enzymes involved in OS, such as catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx), underscoring its potential role in preventing oxidative damage at the cellular level.
-divided as rosemary extract, carnosic acid, rosmarinic acid?

Summary:
-Capacity to chelate transition metal ions, particularly ironChelator (Fe2+) and copper (Cu2+)
-RA plus Cu(II)-induced oxidative DNA damage, which causes ROS
-rosmarinic acid (RA) as a potential inhibitor of MARK4↓ (inhibiting to tumor growth, invasion, and metastasis) activity (IC50 = 6.204 µM)

-Note half-life 1.5–2 hours.
BioAv water-soluble, rapid absorbtion

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 Reactive oxygen species (ROS) ↓ ROS (dominant antioxidant effect) ↓ ROS Driver Antioxidant / redox buffering Rosmarinic acid is a strong phenolic antioxidant; cancer effects are largely redox-modulatory rather than cytotoxic
2 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Secondary Suppression of inflammatory survival signaling NF-κB inhibition explains anti-inflammatory, anti-proliferative, and chemopreventive effects
3 MAPK signaling (ERK / JNK / p38) ↓ ERK; ↑ JNK/p38 (context-dependent) ↔ minimal Secondary Stress-modulated signaling MAPK modulation reflects redox-sensitive signaling rather than direct kinase inhibition
4 Cell cycle regulation ↑ G0/G1 arrest (mild) ↔ spared Phenotypic Cytostatic growth control Growth inhibition is modest and non-cytotoxic in most models
5 Apoptosis ↑ apoptosis (weak / context-dependent) ↓ apoptosis Phenotypic Threshold-dependent cell death Apoptosis is not a dominant mechanism and usually requires high doses or co-stress
6 NRF2 antioxidant response ↑ NRF2 (adaptive) ↑ NRF2 (protective) Adaptive Antioxidant gene induction NRF2 activation reflects reinforcement of antioxidant capacity


Cyt‑c, cyt-c Release into Cytosol: Click to Expand ⟱

Type:
Cytochrome c
** The term "release of cytochrome c" ** an increase in level for the cytosol.
Small hemeprotein found loosely associated with the inner membrane of the mitochondrion where it plays a critical role in cellular respiration. Cytochrome c is highly water-soluble, unlike other cytochromes. It is capable of undergoing oxidation and reduction as its iron atom converts between the ferrous and ferric forms, but does not bind oxygen. It also plays a major role in cell apoptosis.

The term "release of cytochrome c" refers to a critical step in the process of programmed cell death, also known as apoptosis.
In its new location—the cytosol—cytochrome c participates in the apoptotic signaling pathway by helping to form the apoptosome, which activates caspases that execute cell death.
Cytochrome c is a small protein normally located in the mitochondrial intermembrane space. Its primary role in healthy cells is to participate in the electron transport chain, a process that helps produce energy (ATP) through oxidative phosphorylation.
Mitochondrial outer membrane permeability leads to the release of cytochrome c from the mitochondria into the cytosol.
The release of cytochrome c is a pivotal event in apoptosis where cytochrome c moves from the mitochondria to the cytosol, initiating a chain reaction that leads to programmed cell death.

On the one hand, cytochrome c can promote cancer cell survival and proliferation by regulating the activity of various signaling pathways, such as the PI3K/AKT pathway. This can lead to increased cell growth and resistance to apoptosis, which are hallmarks of cancer.
On the other hand, cytochrome c can also induce apoptosis in cancer cells by interacting with other proteins, such as Apaf-1 and caspase-9. This can lead to the activation of the intrinsic apoptotic pathway, which can result in the death of cancer cells.
Overexpressed in Breast, Lung, Colon, and Prostrate.
Underexpressed in Ovarian, and Pancreatic.
