There is an inflammatory enzyme called cyclooxygenase-2 (COX-2) that is abundantly expressed in colon cancer cells. It also plays a key role in colon tumorigenesis (new cancer growth). Therefore, compounds inhibiting COX-2 transcriptional activity (gene RNA replication) potentially have a chemopreventive property. Finding natural compounds to inhibit COX-2 pathways should prove exciting and promising.
In a recent study, an assay method for estimating COX-2 transcriptional activity in human colon cancer cells was established using a β-galactosidase reporter gene system. The study examined effects made of various medicinal herbs and their ingredients for an inhibitory effect on COX-2 transcriptional activity.
They found that berberine, an isoquinoline alkaloid present in plants of the genera Berberis and Coptis from Oregon grape root and Bayberry, effectively inhibits COX-2 transcriptional activity in colon cancer cells in a dose- and time-dependent manner at concentrations higher than 0.3 μM. These findings may further explain the mechanism of anti-inflammatory and anti-tumor promoting effects of berberine.
Our BerberClear supplies high potency berberine combined with alpha lipoic acid to help support optimal blood sugar and insulin levels, cardiovascular health, and liver health. Berberine is an alkaloid compound found in the roots, rhizomes, stems and bark of several plants commonly used in botanical and Chinese medicine, such as goldenseal, Oregon grape, barberry, and Berberis aristata.
Lipoic acid is best known for its antioxidant properties and its ability to support healthy insulin secretion and sensitivity. It is also a key cofactor for mitochondrial enzymes involved in cellular metabolism and energy (ATP) production. Made with non-GMO ingredients.
Metastasis and angiogenesis is to be avoided at all cost. There is increasing evidence that two chemicals, urokinase-type plasminogen activator (u-PA) and matrix metalloproteinases (MMPs) play an important role in cancer spread and vasculization. Inhibition of u-PA and MMPs could suppress migration and invasion of cancer cells. Berberine reported to have anti-cancer effects in different human cancer cell lines by inhibiting u-PA and MMPs according to another study.
The treatment of human prostate cancer cells (PC-3) with berberine was shown to induce dose-dependent apoptosis. Berberine-induced apoptosis was associated with the disruption of the mitochondrial membrane potential, release of apoptogenic molecules (cytochrome c and Smac/DIABLO) from mitochondria and cleavage of caspase-9,-3 and PARP proteins. In xenograft in vivo studies, berberine reduced tumor weights and volumes accompanied with apoptotic cell death and increased expression of apoptotic cell death proteins.
