Safe, affordable and efficacious agents are urgently required for cancer prevention. Sesamin, a lipid‑soluble lignan from sesame (Sesamum indicum) displays anticancer activities through an unknown mechanism. In the present study, the anticancer activity of sesamin via cyclooxygenase 2 (COX2) was
Icariside II (IS) isolated from the roots of Epimedium koreanum Nakai was known to have antioxidant activity and inhibit melanogenesis and hypoxia inducible factor. We report here for the first time that IS induces apoptosis through its anti-inflammatory effects in PC-3 prostate cancer cells. IS
Cancer is predicted to become the leading cause of death--surpassing heart disease--by the end of this decade. Colorectal cancer is a major health concern, with more than 1,000,000 new cases and 500,000 deaths expected worldwide per year. There is much evidence to suggest a link between the
OBJECTIVE
Epidemiologic studies indicate that the use of nonsteroidal anti-inflammatory drugs, which inhibit cyclooxygenase activity, reduce the risk of colorectal cancer. In addition, several studies demonstrate increased expression of cyclooxygenase-2 in human colorectal cancer tissues. However,
Use of nonsteroidal anti-inflammatory drugs such as aspirin, which are known to inhibit cyclooxygenase activity, reduces the relative risk of colorectal cancer in humans by 40-50%. Animal and human studies have shown a 50-80% reduction in tumour multiplicity following treatment with a variety of
Non-steroidal anti-inflammatory drugs (NSAIDs) are the most widely used therapeutic agents in the treatment of pain, inflammation and fever. They may also have a role in the management of cancer prevention, Alzheimer's disease and prophylaxis against cardiovascular disease. These drugs act primarily
Cyclooxygenase-2 (Cox2) is an inductible isoenzyme of cyclooxygenase undetectable in normal colonic mucosa and overexpressed in 80% colonic tumor. Several works in vitro and in vivo showed that Cox2 plays a key role in the multistep process of colorectal tumorigenesis such apoptosis inhibition of
Cyclooxygenase-2 (Cox2) is an inductible isoenzyme of cyclooxygenase undetectable in normal colonic mucosa and overexpressed in 80% colonic tumor. Several works in vitro and in vivo showed that Cox2 plays a key role in the multistep process of colorectal tumorigenesis such apoptosis inhibition of
Researchers have found dramatically elevated cyclooxygenase-2 (COX-2) expression in a striking number of malignant and premalignant conditions. Epidemiological evidence is in favour of aspirin and non steroidal anti-inflammatory drugs (NSAIDs) preventing certain tumors. More than 100 years after
Prior to the discovery of cyclooxygenase-2 (COX-2), a beneficial association was shown between chronic usage of non steroidal anti-inflammatory drugs (NSAIDs), that non-selectively inhibit both cyclooxygenase-1 (COX-1) and COX-2, and prevention of colorectal cancer. The cloning of COX-2 allowed the
COX-2 is an isoenzyme of cyclooxygenase that is increased in response to growth factors, cytokines, and other mitogenic stimuli. Upregulation of COX-2 gene expression and functional activity is an early event in colorectal tumor formation. The long-term use of cyclooxygenase inhibitors, such as
There is now substantial evidence for the role of cyclooxygenase (COX)-2 in causation and prevention of cancer. Selective COX-2 inhibitors (coxibs) were considered attractive candidate chemoprevention agents; however, concerns over the toxicity of systemic selective inhibition have cast some doubt
There is epidemiological evidence that suggests an inverse association between the consumption of non-steroidal anti-inflammatories (NSAIDs) and the risk of developing certain neoplasms. This association led to the identification of the therapeutic target of these drugs, cyclooxygenase type 2
Carcinogenesis results from the long-term accumulation of genetic and epigenetic aberrations at the molecular level, which are under constant selection pressure for growth advantage. Recognizing that cancer is the result of this long-term, multi-step process provides opportunities for molecularly
Epidemiological evidences suggest that chronic use of aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) might be associated with a reduced risk of gastrointestinal cancers, including gastric cancer. The pre-cancerous gastric lesions and gastric cancers over-expressed cyclooxygenase (COX)-2.
