Cancer is a multistep process resulting in uncontrolled cell division. It results from aberrant signaling pathways that lead to uninhibited cell division and growth. Various recent epidemiological studies have indicated that consumption of cruciferous vegetables, such as garden cress, broccoli, etc., reduces the risk of cancer. Isothiocyanates (ITCs) have(More)
Chronic inflammation of rheumatoid arthritis (RA) is promoted by proinflammatory cytokines and closely linked to angiogenesis. In the present study, we investigated the anti-inflammatory effects of emodin (1,3,8-trihydroxy-6-methyl-anthraquinone) isolated from the root of Rheum palmatum L. in interleukin 1 beta (IL-1β) and lipopolysaccharide(More)
Although cryptotanshinone (CT) was known to exert antitumor activity in several cancers, its molecular mechanism under hypoxia still remains unclear. Here, the roles of AEG-1 and HIF-1α in CT-induced antitumor activity were investigated in hypoxic PC-3 cells. CT exerted cytotoxicity against prostate cancer cells and suppressed HIF-1α accumulation and AEG-1(More)
Although ursolic acid isolated from Oldenlandia diffusa (Rubiaceae) was known to have anticancer activities in prostate, breast and liver cancers, the underlying mechanism of ursolic acid in ovarian cancer cells was not investigated so far. In the present study, the apoptotic mechanism of ursolic acid was elucidated in SK-OV-3 ovarian cancer cells by(More)
Although brazilin [7,11b-dihydrobenz(b)indeno[1,2-d]pyran-3,6a,9,10(6H)-tetrol] isolated from Caesalpinia sappan was known to have various biological activities, including anti-inflammation, antibacteria, and antiplatelet aggregation, there is no report yet on its anticancer activity. In the present study, the anticancer mechanism of brazilin was(More)
Though glycyrrhetinic acid (GA) from Glycyrrhiza glabra was known to exert antioxidant, antifilarial, hepatoprotective, anti-inflammatory and anti-tumor effects, the antitumor mechanism of GA was not clearly elucidated in non-small cell lung cancer cells (NSCLCCs). Thus, in the present study, the underlying apoptotic mechanism of GA was examined in NCI-H460(More)
Since the dysregulation of ribosome biogenesis is closely associated with tumor progression, in the current study, the critical role of ribosome biogenesis related signaling was investigated in melatonin and/or puromycin induced apoptosis in MDA-MB-231 breast cancer cells. Despite its weak cytotoxicity, melatonin from 3 mM attenuated the expression of 45S(More)
Although ZNF746, also known as Parkin-interacting substrate (PARIS), has been reported to suppress peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) and its target gene NRF-1 leading to the neurodegeneration in Parkinson's disease, its function in tumorigenesis has yet to be investigated. Thus, in the present study, the role of ZNF746 in(More)
To evaluate melatonin's ability to enhance ovarian cancer cells to cisplatin treatment for ovarian cancer, this study was performed. Melatonin by itself had no significant cytotoxicity against SK-OV-3 cells, while cisplatin suppressed the cell viability in a dose-dependent manner. Combined treatment with cisplatin and melatonin synergistically inhibited the(More)
Among many signals to regulate hypoxia inducible factor 1α (HIF-1α), sphingosine kinase 1 (SPHK1) is also involved in various biological activities such as cell growth, survival, invasion, angiogenesis, and carcinogenesis. Thus, in the present study, molecular mechanisms of coumestrol were investigated on the SPHK1 and HIF-1α signaling pathway in hypoxic(More)
