| Copper Metal Copper levels are considerably elevated in various malignancies. Copper [Cu(II)] is a transition and trace element in living organisms. It increases reactive oxygen species (ROS) and free-radical generation that might damage biomolecules like DNA, proteins, and lipids. Copper (dietary/physiology) ≠ copper-loading therapeutics ≠ copper nanoparticles. For Cu nanoparticles, the dominant and most reproducible theme is toxicity via ROS → mitochondrial damage/genotoxicity, not clean tumor selectivity. - Copper acts as a critical cofactor for numerous enzymes involved in redox reactions, energy production, and connective tissue formation. - Increased copper levels in the tumor microenvironment can enhance angiogenic signaling and thus supply the tumor with necessary oxygen and nutrients, facilitating tumor growth and metastasis. - Copper can participate in redox cycling reactions, similar to the Fenton reaction, leading to the production of reactive oxygen species (ROS). - Cancer cells often exhibit altered copper homeostasis, with some studies showing elevated copper levels in tumor tissues relative to normal tissues. Two main approaches are: - Copper Chelation: Drugs that bind copper (chelators) can reduce the bioavailability of copper, potentially inhibiting angiogenesis and other copper-dependent tumor processes. - Copper Ionophores: These agents facilitate the transport of copper into cancer cells to induce cytotoxicity by elevating intracellular copper levels beyond a tolerable threshold, leading to cell death. - Depletion of glutathione and stimulation of lipid peroxidation, catalase and superoxide dismutase. - Studies have shown that the level of copper in tumour cells and blood serum from cancer patients is elevated, and the conclusion is that cancer cells need more copper than healthy cells. (but also sometimes depleted). - Copper is a double-edged sword, maintaining normal cell development and promoting tumor development. - Tumor tissue has a higher demand for copper and is more susceptible to copper homeostasis, copper may modulate cancer cell survival through reactive oxygen species (ROS) excessive accumulation, proteasome inhibition and anti-angiogenesis.

| P65, also known as RelA, is a subunit of the NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) transcription factor complex. NF-κB plays a crucial role in regulating immune response, inflammation, and cell survival. Due to its role in cancer progression, p65 and the NF-κB pathway are considered potential therapeutic targets. Inhibitors of NF-κB signaling are being explored in preclinical and clinical studies as potential cancer treatments. Many studies have reported that p65 is overexpressed in various types of cancers, including breast, prostate, lung, and colorectal cancers. In some cancers, elevated p65 levels correlate with higher grades of tumors and advanced stages of disease. "RELA proto-oncogene, NF-κB subunit." It encodes the p65 protein, which is a central component of the NF‑κB transcription factor complex. -Chronic activation of RELA and the NF‑κB pathway is frequently associated with cancer progression, promoting inflammation-driven tumorigenesis, chemoresistance, and metastasis. -RELA interacts with other oncogenic signaling networks (for example, STAT3 and MAPK pathways), further integrating environmental signals that favor cancer progression. RELA (p65) is a critical subunit of the NF‑κB transcription factor complex, involved in the regulation of genes that control inflammation, cell survival, and proliferation. In the context of cancer, aberrant activation and overexpression of RELA are frequently associated with aggressive tumor behavior, therapy resistance, and poorer patient outcomes in cancers such as breast, lung, colorectal, and pancreatic cancers, among others. RELA emerges as a potential key contributor to the suppression of glycolysis, mitochondrial respiration, and ATP production in cancer cells. (RELA knockdown signifcantly reduced the tumorigenic. potential of various pancreatic cancer cell lines). |
