Inhibition of Akt/mTOR Signaling by the Dietary Flavonoid Fisetin
Authors: Deeba N. Syed, Vaqar M. Adhami, Mohammad Imran Khan and Hasan MukhtarPlants have long been providing mankind with remedies of different ailments. Flavonoids, a family of naturally occurring polyphenolic compounds are ubiquitous in plants. Development of polyphenol-based drugs has not attracted much attention by researchers and drug companies. Therefore, despite extensive studies on polyphenols, this vast group of compounds is underrepresented in clinical medicine. Fisetin (3,7,3',4'-tetrahy Read More

Targeted Regulation of PI3K/Akt/mTOR/NF-κB Signaling by Indole Compounds and their Derivatives: Mechanistic Details and Biological Implications for Cancer Therapy
Authors: Aamir Ahmad, Bernhard Biersack, Yiwei Li, Dejuan Kong, Bin Bao, Rainer Schobert, Subhash B. Padhye and Fazlul H. SarkarIndole compounds, found in cruciferous vegetables, are potent anti-cancer agents. Studies with indole-3-carbinol (I3C) and its dimeric product, 3,3'-diindolylmethane (DIM) suggest that these compounds have the ability to deregulate multiple cellular signaling pathways, including PI3K/Akt/mTOR signaling pathway. These natural compounds are also effective modulators of downstream transcription factor NF-κB signaling which mi Read More

Deregulation of PI3K/Akt/mTOR Signaling Pathways by Isoflavones and its Implication in Cancer Treatment
Authors: Aamir Ahmad, Bernhard Biersack, Yiwei Li, Dejuan Kong, Bin Bao, Rainer Schobert, Subhash B. Padhye and Fazlul H. SarkarCancer remains a difficult disease to manage because of the deregulation of numerous signaling pathways that are associated with its development and progression. One such pathway is the phosphoinositide 3-kinase (PI3K) – protein kinase B (Akt) - mammalian target of rapamycin (mTOR) signaling network, which is known to be associated with poor prognosis in many human cancers. Targeted inhibition of this signa Read More

Inhibition of mTOR Signaling by Quercetin in Cancer Treatment and Prevention
More LessQuercetin is an abundant micronutrient in our daily diet. Several beneficial health effects are associated with the dietary uptake of this bioflavonoid, including alleviating effects on chronic inflammation and atherosclerosis. A variety of in vitro data indicate a possible use of quercetin for cancer treatment purposes through its interaction with multiple cancer-related pathways. Among these, recent data reveal that quercetin can i Read More

Targeting mTOR: Evaluating the Therapeutic Potential of Resveratrol for Cancer Treatment
More LessResveratrol (3,4′,5-trihydroxystilbene; RSV), a natural polyphenol found in a variety of daily food including grapes and red wine, has long been suspected to have multifaceted health beneficial properties, including anti-inflammation, anti-oxidant, and anticancer activities. Over the past few years, numerous studies have suggested that suppressing the activity of mammalian target of rapamycin (mTOR), a critical regulator of Read More

Tocotrienols Target PI3K/Akt Signaling in Anti-Breast Cancer Therapy
Authors: Paul W. Sylvester and Nehad M. AyoubThe PI3K/Akt signaling pathway mediates mitogen-dependent growth and survival in various types of cancer cells, and inhibition of this pathway results in tumor cell growth arrest and apoptosis. Tocotrienols are natural forms of vitamin E that displays potent anticancer activity at treatment doses that had little or no effect on normal cell viability. Mechanistic studies revealed that the anticancer effects of γ-tocotrienol were as Read More

Natural Products Targeting Autophagy via the PI3K/Akt/mTOR Pathway as Anticancer Agents
Authors: Hui Sun, Zhaoye Wang and Juan Sebastian YakisichThe phosphatidylinositol 3-kinase/Akt/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway is a key regulator of authophagy. Natural products show anticancer activity and often induce apoptosis or autophagy. The crosstalk between these two types of cell death makes autophagy an interesting target since drugs targeting this process not only can induce cell death by inducing autophagy but can also sensitize cells to Read More

From Bacteria to Antineoplastic: Epothilones A Successful History
Malignancies are a major cause of morbidity and mortality worldwide. Cancer is a cell disease, characterized by a deviation of the control mechanisms of proliferation and differentiation of cells. Among the treatments available, chemotherapy is often the first choice. Epothilones are a new class of anticancer drugs that act by interacting with cellular microtubules interrupting the proliferation of cancer cells. Many synth Read More

From Na+/K+-ATPase and Cardiac Glycosides to Cytotoxicity and Cancer Treatment
Authors: Petr Babula, Michal Masarik, Vojtech Adam, Ivo Provaznik and Rene KizekThe cardiac glycosides are a group of compounds isolated from plants and some animals. They have been used in therapy for heart failure for many years. The cytotoxic effect of many cardiac glycosides has been demonstrated, but the mechanism of action is very complicated and complex, and Na+/K+-ATPase surely plays a crucial role in it. On the other hand, Na+/K+-ATPase is regulated by many endogenous fact Read More

Suppression of Oncoprotein Her-2 and DNA Damage after Treatment with Flavan-3- ol Vitis labrusca Extract
More LessHepatocellular carcinoma and breast cancer are the most prevalent cancers in the world with high morbidity and mortality. Although there are effective drugs for treating advanced stages of liver and breast cancers, the prognosis for patients with liver cancer remains poor, and patients with breast cancer show considerable mortality. Therefore, it is crucial to explore new therapeutic agents for the inhibition of carcinogen Read More

BIBR 1532 Increases Arsenic Trioxide-mediated Apoptosis in Acute Promyelocytic Leukemia Cells: Therapeutic Potential for APL
The current treatment of acute promyelocytic leukemia with arsenic trioxide (ATO) has increased long-lasting complete remissions; however, a proportion of patients continues to die eventually as a result of disease recurrence. In an effort to enhance the effectiveness of the APL treatment, we designed experiments to evaluate the effects of ATO in combination with the lead compound of non-nucleoside inhibitor of telomera Read More

Oncogenic MicroRNA-27a is a Target for Genistein in Ovarian Cancer Cells
Authors: Linlin Xu, Jingying Xiang, Jian Shen, Xi Zou, Sulan Zhai, Yongxiang Yin, Ping Li, Xuerong Wang and Qingmin SunMicroRNAs (miRNAs) are emerging as important regulators in various pathobiological processes in cancer. Genistein, as a major isoflavonoid isolated from dietary soybean, possesses a wide variety of biological activities particularly in cancer prevention. However, the molecular mechanisms by which genistein elicits its effects on ovarian cancer cells have not been fully elucidated. In this study, we reported that e Read More

Synthesis and Antiproliferative Effects of 5,6-Disubstituted Pyridazin-3(2H)-ones Designed as Conformationally Constrained Combretastatin A-4 Analogues
Novel 5,6-disubstituted pyridazin-3(2H)-one derivatives were designed and synthesized as combretastatin A-4 analogues. Our objective was to overcome the spontaneous cis to trans isomerization of the compound. We therefore replaced the cis-double bond with a pyridazine ring. The antiproliferative activity of the novel analogues was evaluated against four human cancer cell lines (HL-60, MDAMB- 435, SF-295 and HC Read More
