“…34 The apoptosis is mediated by a mitochondrial-dependent pathway and calpain, a Ca +2 regulated protein, which also plays a role in the resveratrol-mediated apoptosis in MCF-7 cells. 34 Tang et al 35 reported that resveratrol induces nuclear accumulation of COX-2 protein in human breast cancer MCF-7 and MDA-MB-231 cell cultures, a process dependent on MAPK ½, and AP-1 eventually results in a p53-mediated apoptosis. The compound also decreases the telomerase activity in vitro.…”

Extensive research within the last decade has revealed that most chronic illnesses such as cancer, cardiovascular and pulmonary diseases, neurological diseases, diabetes, and autoimmune diseases exhibit dysregulation of multiple cell signaling pathways that have been linked to inflammation. Thus mono-targeted therapies developed for the last two decades for these diseases have proven to be unsafe, ineffective and expensive. Although fruits and vegetables are regarded to have therapeutic potential against chronic illnesses, neither their active component nor the mechanism of action is well understood. Resveratrol (trans-3, 5, 4'-trihydroxystilbene), a component of grapes, berries, peanuts and other traditional medicines, is one such polyphenol that has been shown to mediate its effects through modulation of many different pathways. This stilbene has been shown to bind to numerous cell-signaling molecules such as multi drug resistance protein, topoisomerase II, aromatase, DNA polymerase, estrogen receptors, tubulin and F1-ATPase. Resveratrol has also been shown to activate various transcription factor (e.g., NFκB, STAT3, HIF-1α, β-catenin and PPAR-γ), suppress the expression of antiapoptotic gene products (e.g., Bcl-2, Bcl-X L , XIAP and survivin), inhibit protein kinases (e.g., src, PI3K, JNK and AKT), induce antioxidant enzymes (e.g., catalase, superoxide dismutase and hemoxygenase-1), suppress the expression of inflammatory biomarkers (e.g., TNF, COX-2, iNOS and CRP), inhibit the expression of angiogenic and metastatic gene products (e.g., MMPs, VEGF, cathepsin D and ICAM-1), and modulate cell cycle regulatory genes (e.g., p53, Rb, PTEN, cyclins and CDKs). Numerous animal studies have demonstrated that this polyphenol holds promise against numerous age-associated diseases including cancer, diabetes, Alzheimer, cardiovascular and pulmonary diseases. In view of these studies, resveratrol's prospects for use in the clinics are rapidly accelerating. Efforts are also underway to improve its activity in vivo through structural modification and reformulation. Our review describes various targets of resveratrol and their therapeutic potential.

Abstract.Resveratrol is a polyphenolic compound, which has been revealed to induce apoptosis in numerous human cancer cells; however, the effects of resveratrol on the migration and invasion of human bladder cancer cells have not been reported. The present study aimed to evaluate the anti-metastatic potential of resveratrol against bladder cancer and its mechanism of action. The results indicated that resveratrol inhibits the adhesion, migration and invasion of bladder cancer cells in a dose-dependent manner. Resveratrol was shown to significantly inhibit the expression and secretion of matrix metalloproteinase (MMP)-2 and MMP-9 in bladder cancer cells. Furthermore, resveratrol suppressed the phosphorylation of c-Jun N-terminal kinase and extracellular signal-regulated protein kinase. In conclusion, the present study is the first, to the best of our knowledge, to demonstrate that resveratrol may be considered a novel anticancer agent for the treatment of bladder cancer via the inhibition of migration and invasion. IntroductionBladder cancer is the fourth most common type of cancer, and was the cause of >11,510 cases of cancer-associated mortality among men in the USA in 2014 (1). The majority of bladder cancer cases are noninvasive, low-grade transitional cell carcinoma (TCC); however, ≤30% of all diagnosed tumors are classified as invasive TCC, which is associated with high mortality (2). Notably, among all of the various types of cancer, bladder cancer exhibits a significantly high incidence of recurrence post-treatment, and therefore is recognized as the most expensive cancer to treat. Due to the high prevalence and frequent tumor recurrence associated with bladder cancer, the exploration of preventative strategies is required.Previous epidemiological and scientific studies have indicated that plant-derived phytochemicals may be beneficial in the prevention and treatment of cancer (3-5). Resveratrol is a polyphenolic compound, which is present in grapes (red wine), knotweed, peanuts, mulberries and other plants. Numerous studies have suggested that resveratrol may prevent the progression of various pathologies, including vascular diseases, ischemic injuries, cancer and neurodegenerative disorders (6-8). Furthermore, it has previously been confirmed that resveratrol exerts antiproliferative and/or apoptotic effects on leukemia, prostate, breast and colon cancers cells in vitro (9-12). Previous studies regarding the anticancer effects of resveratrol have focused on its anti-invasive and anti-metastatic activities (13-15). However, to the best of our knowledge, there is currently no evidence as to whether resveratrol may inhibit the migration and invasion of human bladder cancer cells.Metastasis is one of the hallmarks of advanced cancer progression, and cancer cell migration and invasion are crucial events in bladder cancer metastasis. Matrix metalloproteinases (MMPs), including MMP-2 and MMP-9, degrade the basement membrane and extracellular matrix (ECM), and are therefore considered crucial proteolytic protei...

,5,3Ј-Triiodo-L-thyronine (T3), but not L-thyroxine (T4), activated Src kinase and, downstream, phosphatidylinositol 3-kinase (PI3-kinase) by means of an ␣ v␤3 integrin receptor on human glioblastoma U-87 MG cells. Although both T 3 and T4 stimulated extracellular signal-regulated kinase (ERK) 1/2, activated ERK1/2 did not contribute to T 3-induced Src kinase or PI3-kinase activation, and an inhibitor of PI3-kinase, LY-294002, did not block activation of ERK1/2 by physiological concentrations of T 3 and T4. Thus the PI3-kinase, Src kinase, and ERK1/2 signaling cascades are parallel pathways in T 3-treated U-87 MG cells. T3 and T4 both caused proliferation of U-87 MG cells; these effects were blocked by the ERK1/2 inhibitor PD-98059 but not by LY-294002. Smallinterfering RNA knockdown of PI3-kinase confirmed that PI3-kinase was not involved in the proliferative action of T 3 on U-87 MG cells. PI3-kinase-dependent actions of T 3 in these cells included shuttling of nuclear thyroid hormone receptor-␣ (TR␣) from cytoplasm to nucleus and accumulation of hypoxia-inducible factor (HIF)-1␣ mRNA; LY-294002 inhibited these actions. Results of studies involving ␣v␤3 receptor antagonists tetraiodothyroacetic acid (tetrac) and Arg-Gly-Asp (RGD) peptide, together with mathematical modeling of the kinetics of displacement of radiolabeled T3 from the integrin by unlabeled T3 and by unlabeled T4, are consistent with the presence of two iodothyronine receptor domains on the integrin. A model proposes that one site binds T3 exclusively, activates PI3-kinase via Src kinase, and stimulates TR␣ trafficking and HIF-1␣ gene expression. Tetrac and RGD peptide both inhibit T3 action at this site. The second site binds T4 and T3, and, via this receptor, the iodothyronines stimulate ERK1/2-dependent tumor cell proliferation. T3 action here is inhibited by tetrac alone, but the effect of T4 is blocked by both tetrac and the RGD peptide. thyroid hormone; phosphatidylinositol 3-kinase; extracellular signal-regulated kinase 1/2; integrin ␣v␤3; glioblastoma cells; Src kinase; mitogenactivated protein kinase; intracellular hormone receptor trafficking ACTIONS OF THYROID HORMONE [L-thyroxine (T 4 ); 3,5,3Ј-triiodo-L-thyronine (T 3 )] that are independent of ligand binding to nuclear thyroid hormone receptors are called nongenomic actions. Nongenomic effects of thyroid hormone are initiated outside the cell nucleus but may culminate in complex cellular events that are nucleus mediated (7, 8, 26 -29). Initiation of nongenomic actions includes a plasma membrane receptor for T 4 and T 3 on integrin ␣ v ␤ 3 that is linked to mitogen-activated protein kinase [extracellular signal-regulated kinase (ERK) 1/2] for transduction of the hormone signal (3) and nuclear receptors residing in the cytosol of unstimulated cells, such as thyroid hormone receptor (TR) ␤1 (28).The phosphatidylinositol 3-kinase (PI3-kinase)/protein kinase B (Akt) pathway is an important regulator of cellular growth, metabolism, and survival (13, 19).
