Pleckstrin homology domain leucine-rich repeat protein phosphatase 2 (PHLPP2) has been known to exert tumor suppressive activity for long without much knowledge about its regulation and implications. Protein kinase B (Akt), Protein kinase C (PKC) and Ribosomal protein S6 Kinase (S6K) are known downtargets of PHLPP2, regulating a plethora of life processes viz. cell growth, survival and evasion from apoptosis. Present study decoded the crucial role of PHLPP2 in inducing apoptosis by its interaction with the newly found binding partner Mammalian sterile 20-like kinase 1 (Mst1) in berberine (BBR)-treated human hepatoma cells...

Berberine (BBR) is considered a multi-target drug that has significant advantages. In contrast to its significant pharmacological effects in clinic, the plasma level of BBR is very low. Our previous work revealed that dihydroberberine (dhBBR) could be an absorbable form of BBR in the intestine, and butyrate is an active metabolite that is generated by gut bacteria in rats. In this study, for the first time we describe gut microbiota-regulated pharmacokinetics in beagle dogs after oral administration of BBR by single (50 mg/kg) or multiple doses (50 mg/kg/d) for 7 days...

The reactivation of senescence in cancer and the subsequent clearance of senescent cells are suggested as therapeutic intervention in the eradication of cancer. Several natural compounds that activate Nrf2 (nuclear factor erythroid-derived 2-related factor 2) pathway, which is involved in complex cytoprotective responses, have been paradoxically shown to induce cell death or senescence in cancer. Promoting the cytoprotective Nrf2 pathway may be desirable for chemoprevention, but it might be detrimental in later stages and advanced cancers...

Our previous studies indicated that combination of Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and PPARγ ligand Troglitazone (TZD), can induce significant apoptosis in various TRAIL-resistant prostate and hepatocellular carcinoma (HCC) cells. These also suggested serine/threonine kinase AMP-activated protein kinase (AMPK) to be a mediator of TRAIL-TZD-induced apoptosis. To further validate AMPK's role in TRAIL sensitization, we determined the apoptotic potential of TRAIL in combination with the natural compound Berberine (BBR), the latter being a potent activator of AMPK...

Gliomas, the most common primary malignant brain tumor, exhibit high metabolic activity. The targeting of metabolism alterations, particularly in mitochondria, is emerging as an efficient approach for curing cancers. Here, we showed that berberine, a natural compound that is used as an antibacterial agent, could reduce cellular viability and induce oncosis-like death, characterized by cell swelling, cytoplasmic vacuoles and plasma membrane blebbing, in gliomas, and that these effects were correlated with intracellular adenosine triphosphate (ATP) depletion...

Intricate health problems, such as insulin resistance (IR) and its associated diseases, call for multi-targeted therapies with few side effects. Based on traditional Chinese medicine (TCM), Dai-Zong-Fang (DZF) is an herbal formula mainly composed of Rhizoma Coptidis (Huanglian) and Fructus Aurantii Immaturus (Zhishi), of which berberine and naringin are the main constituents. Though DZF has been clinically used for treatment of IR and metabolic syndrome for decades, its mechanism in vivo remains unknown. In the present study, we observed that both DZF and metformin, the first-line drug for type 2 diabetes, ameliorated insulin resistance with significant improvement of oral glucose tolerance test (OGTT) and homeostasis model assessment of IR (HOMA-IR) level in diabetic C57BL/Ksj-Lepr db -/- ( db/db ) mice...
