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.

ER Stress, endoplasmic reticulum (ER) stress signaling pathway: Click to Expand ⟱
Source:
Type:
Protein expression of ATF, GRP78, and GADD153 which is a hall marker of ER stress.
The endoplasmic reticulum (ER) stress signaling pathway plays a crucial role in maintaining cellular homeostasis and responding to various stressors, including those encountered in cancer. When cells experience stress, such as the accumulation of misfolded proteins, they activate a series of signaling pathways collectively known as the unfolded protein response (UPR). The UPR aims to restore normal function by enhancing the protein-folding capacity of the ER, degrading misfolded proteins, and, if the stress is unresolved, triggering apoptosis.
The activation of ER stress pathways can contribute to resistance against chemotherapy and targeted therapies. Cancer cells may utilize the UPR to survive treatment-induced stress, making it challenging to achieve effective therapeutic outcomes.

-ER stress-associated proteins include: phosphorylation of PERK, eIF2α, ATF4, CHOP and cleaved-caspase 12
