Garcinol, or polyisoprenylated benzophenone, isolated from the rind of fruiting bodies of Garcinia indica, has been used in traditional medicine for its potential antiinflammatory and antioxidant properties. The objective of this study was to investigate the effect of garcinol on pancreatic cancer (PaCa) cell viability and proliferation. For this, 2 human(More)
MicroRNAs (miRNAs) are small noncoding RNAs that play critical roles in regulating various cellular functions by transcriptional silencing. miRNAs can function as either oncogenes or tumor suppressors (oncomirs), depending on cancer types. In our study, using miRNA microarray, we observed that downregulation of the Notch-1 pathway, by delta-tocotrienol,(More)
A modified tetrazolium-based colorimetric assay was used to determine the anti-HIV activities of ddAzThd, ddCyd, ddIno, and PFA. In this assay, poly-1-lysine-coated plates were used to attach the MT-2 cells to the bottom of the plates. A fixed amount of virus (50 TCID50) was used in each well. A modified version of the formula published by Pauwels et al.(More)
ETHNOPHARMACOLOGICAL RELEVANCE The stem bark of Mammea africana is widely distributed in tropical Africa and commonly used in traditional medicine. This study aims to identify the active compound in Mammea africana and to evaluate its antimicrobial and antiproliferative activity. MATERIALS AND METHODS Methanol extract from the bark of the Mammea africana(More)
Non-small cell lung cancer (NSCLC), accounting for 80% of lung cancers, is the leading cause of all cancer deaths. Previously, we demonstrated that delta-tocotrienol inhibits NSCLC cell proliferation, invasion and induces apoptosis by down-regulation of the Notch-1 signaling pathway. The objective of this study was to investigate whether delta-tocotrienol,(More)
Lung cancer is the leading cause of death among all cancers. Non-small cell lung cancer accounts for 80% of lung cancer with a 5-year survival rate of 16%. Notch pathway, especially Notch-1 is up-regulated in a subgroup of non-small cell lung cancer patients. Since Notch-1 signaling plays an important role in cell proliferation, differentiation, and(More)
This study was designed to evaluate whether replacing approximately 40 g/100 g dietary animal fat with vegetable oil would improve plasma lipids and lipoproteins when diets contained prudent levels of total saturated acid (SFA), monounsaturated acid (MUFA) and PUFA. Using a cross-over design, male Cynomolgus monkeys (n = 10) were fed purified diets(More)
Pancreatic cancer (PaCa) is a major health concern due to its aggressiveness and early metastasis. Current treatments for PaCa are limited by development of resistance against therapy. As an alternative strategy, we assessed the combinatorial effect of dietary compounds, garcinol and curcumin, on human PaCa cells (BxPC-3 and Panc-1). A significant (P <(More)
Nuclear factor-kappaB (NF-kappaB) is a ubiquitous redox-sensitive transcription factor involved in the pro-inflammatory response to several factors, including cytokines and oxidative stress. Upon activation, NF-kappaB translocates into the nucleus and binds to specific nucleotide sequences. The cellular responses to inflammatory and stress signals have been(More)
