TQ, Thymoquinone: Click to Expand ⟱
Features: Anti-oxidant, anti-tumor
Thymoquinone is a bioactive compound found in the seeds of Nigella sativa, commonly known as black seed or black cumin.
Pathways:
-Cell cycle arrest, apoptosis induction, ROS generation in cancer cells
-inhibit the activation of NF-κB, Suppress the PI3K/Akt signaling cascade
-Inhibit angiogenic factors such as VEGF, MMPs
-Inhibit HDACs, UHRF1, and DNMTs

-Note half-life 3-6hrs.
BioAv low oral bioavailability due to its lipophilic nature. Note refridgeration of Black seed oil improves the stability of TQ.

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
