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


cycE/CCNE, Cyclin E: Click to Expand ⟱
Source:
Type:
Cyclin E regulates multiple downstream molecules, such as the retinoblastoma susceptibility gene (RB1) and the transcription factor E2F.
Cyclin E (Cyclin E1 and Cyclin E2) is the key regulator of the late G1 → S-phase transition.
Cyclin E is a prognostic marker in breast cancer, its altered expression increased with the increasing stage and grade of the tumor.
Cyclin E is a regulatory protein that plays a critical role in the cell cycle, particularly in the transition from the G1 phase to the S phase. Its expression levels can significantly influence cancer progression and patient prognosis.

Cyclin E expression is frequently elevated in various cancers and is generally associated with poor prognosis. Its role in promoting cell cycle progression makes it a potential biomarker for tumor aggressiveness and patient outcomes.
