OBJECTIVE
SIRT1-activating compounds (STACs) may have potential in the management of cancer. However, the best-studied STAC, the naturally occurring compound resveratrol, is reported to have contradictory effects in combination chemotherapy regimens: It has been shown both to increase and to
Vineatrol(®) 30 is a grapevine-shoot extract, which contains resveratrol as well as considerable amounts of so-called resveratrol oligomers such as hopeaphenol and r2-viniferin. In this study, we analysed whether the two above-mentioned resveratrol oligomers were able to inhibit the growth of the
Resveratrol, a natural product and peroxisome proliferator-activated receptor (PPAR) agonist, has been reported to exert anti-cancer effects in several tumor models. A previous study by our group reported that prostaglandin J2, a PPARγ ligand, inhibited cell proliferation in a uterine sarcoma cell
Malignant tumors of mesenchimal origin such as rhabdomyosarcoma and osteosarcoma are highly aggressive pedriatic malignancies with a poor prognosis. Indeed, the initial response to chemotherapy is followed by chemoresistance. Diallyl disulfide (DADS), resveratrol (RES) and curcumin (CUR) are dietary
Osteosarcoma is a high-grade bone sarcoma with strong invasive ability. However, treatment with traditional chemotherapeutic drugs is limited by low tolerability and side effects. Resveratrol has been reported previously to have selective antitumor effect on various tumor cells while little is known
While anti-tumor activity of resveratrol has been demonstrated for many cancers, little is known about its effects on soft tissue sarcoma. Overexpression of TGF-β1, a protein inhibited by resveratrol, is a well-known feature of the rhabdomyosarcoma (RMS), a type of soft tissue sarcoma. In the
Yuccaols (A, B, C) are phenolic constituents isolated from Yucca schidigera bark characterized by unusual spirostructures made up of a C15 unit and a stilbenic portion closely related to resveratrol. These novel compounds are of particular interest for their antioxidant and anti-inflammatory
Dipterocarpaceous plants contain various resveratrol oligomers that exhibit a variety of biological activities, such as antibacterial and antitumor effects. Previously, we found that vaticanol C, a resveratrol tetramer, exhibits strong cytotoxicity against various tumor cell lines. In the present
BACKGROUND
We have previously reported the crucial roles of oncogenic Kirsten rat sarcoma viral oncogene homolog (KRAS) in inhibiting apoptosis and disrupting cell polarity via the regulation of phosphodiesterase 4 (PDE4) expression in human colorectal cancer HCT116 cells in three-dimensional
Colorectal cancer (CRC) is a major cause of cancer-associated deaths worldwide. Recently, oral administration of resveratrol (trans-3,5,4'-trihydroxystilbene) has been reported to significantly reduce tumor proliferation in colorectal cancer patients, however, with little specific information on
In the field of herpesvirus research, the exact molecular mechanism by which such viruses reactivate from latency remains elusive. Kaposi's sarcoma-associated herpesvirus (KSHV) primarily exists in a latent state, while only 1-3% of cells support lytic infection at any specific time. KSHV
Bone cancer is a malignant primary tumour of the bone with different typing, such as, osteosarcoma, chondrosarcoma, Ewing's sarcoma and fibrosarcoma. Despite the clinical efficacy of conventional therapies of bone cancer, most patients eventually relapse and the disease remains incurable. Therefore,
Differences in ligand-activation of estrogen receptor alpha (ER(alpha)) were investigated in human HepG2 liver carcinoma and U2 osteogenic sarcoma cells transfected with wild-type ER (ER-wt) and variants expressing only activation function 1 (ERAF1) or AF2 (ER-AF2). The estrogen-responsive C3-luc
It has been hypothesized that environmental contaminants that modulate endocrine signaling pathways may be causally linked to adverse health effects in humans. There has been particular concern regarding synthetic estrogens and their role in disrupting normal development of the male reproductive
Recent evidence suggests that inflammatory cytokines and growth factors contribute to arsenite (As)-induced human carcinogenesis. We investigated the expression of inflammatory cytokine mRNAs during the transformation process induced by chronic As exposure in non-tumorigenic human osteogenic sarcoma
