A potent and selective anti-tumor agent on human gastric cancer
June 29, 2009A research article to be published on June 21, 2009 in the World Journal of Gastroenterology addresses this question. The research team led by Professor Yan Li from Shengjing Hospital of China Medical University studied the growth inhibitory effects of Alisol B acetat and determined its mechanism of antitumor activity in human gastric cancer cell line SGC7901.
Professor Li and his colleagues found that Alisol B acetat could inhibit the proliferation of SGC7901 cell in a time and dose dependent manner. Among the various phases of cell cycle, the percentage of cells in S phase was significantly decreased, while the percentage of cells in G1 phase was increased. Flow cytometry assay also showed Alisol B acetate had positive effect on apoptosis. Typical apoptotic morphology such as condensation and fragmentation of nuclei and formation of apoptotic bodies could be observed through electron microscope and phase-contrast microscope. Further investigating the molecular mechanism behind Alisol B acetat -induced apoptosis, cells treated with Alisol B acetat underwent a rapid loss of mitochondrial transmembrane potential, activition of caspase-3, -9, upregulation of Apaf-1 and Bax, and inhibition of the PI3K/Akt in a time-dependent manner.
The researches domenstrated for the first time that Alisol B acetate induced human gastric cancer apoptosis through regulation of mitochondrial and PI3K/AKT signaling pathways Their research results indicate that Alisol B acetate might be used to treat gastric cancer , one of the most common cancers worldwide. By knowing the mechanism of action of Alisol B acetate, it may provide a new therapeutic option, as a potential anticancer agent, in the treatment of gastric cancer.

Gastric Cancer Current Events and Gastric Cancer News RSSIs short-term Celecoxib intervention a effective method for preventing gastric carcinogenesis?
Since the isolation and culture of Helicobacter pylori (H. pylori) in 1983, this bacterium has become accepted as an important human pathogen for the development of gastritis, peptic ulcer, and gastric cancer.
A new explanation of 'Asian paradox'
Although Helicobacter pylori (H. pylori) has been classified as a class I (or definite) carcinogen by World Health Organization (WHO), the controversy as to why only a minority of infected patients develop gastric cancer still remains.
Will genomics help prevent the next pandemic?
This week, the Public Library of Science, an open-access publisher, presents the "Genomics of Emerging Infectious Disease," a collection of essays, perspectives, and reviews that explores how genomics-with all its associated tools and techniques-can provide insights into our understanding of emerging infectious disease.
Protein interaction network can respond Helicobacter pylori infection?
Helicobacter pylori (H pylori) is a gram negative bacterium which infects about 50% of the world population. H pylori colonization causes a strong systemic immune response.
A case of post-gastrectomy acute pancreatitis
Gastrectomy is commonly performed for both benign and malignant lesions. Although the incidence of post-gastrectomy acute pancreatitis (PGAP) is low compared to other well-recognized post-operative complications, it has been reported to be associated with a high mortality rate.
Does Helicobacter pylori eradication therapy prevent gastric cancer?
Although it has been demonstrated that Helicobacter pylori causes gastric cancer, it is still controversial that whether H. pylori eradication therapy is effective in primary prevention of gastric cancer.
New blood tests promise simple, cost-effective diagnosis of gastrointestinal cancers
Promising results from two new blood tests that can aid in the early identification of patients with gastrointestinal (GI) cancers will be presented at Europe's largest cancer congress.
NIH study reveals new genetic culprit in deadly skin cancer
Drawing on the power of DNA sequencing, National Institutes of Health researchers have identified a new group of genetic mutations involved in the deadliest form of skin cancer, melanoma.
PPAR-g agonists have potential therapeutic role in gastric carcinoma?
Recently, the potential of PPAR-γ as a target for the prevention and treatment of cancer has been widely studied.
D2 lymphadenectomy improves the long-term survival for patients with node-negative gastric cancer
Many studies favor an extended lymphadenectomy at the time of a potentially curative gastrectomy for node-positive gastric cancer, and the risk of long-term death tends to decrease when the number of resected lymph nodes increases to about 25.
