Serum fatty acid synthase as a marker of digestive neoplasia

T

he aim of this study is to evaluate FAS as a marker of digestive cancer to measure FAS serum levels in patients with digestive

cancer and explore each digestive cancer metabolic features. Cancer metabolism is a futuristic strategy point for diagnosis

and management. Lipid metabolism in particular is a vast uncharted territory for targeting tumor control. It is well known

that many cancer cells up-regulate of fatty acid synthesis. Cancer cells require fatty acid for building blocks of new organelles

and cells. Fatty Acid Synthase (FAS) is the enzyme responsible for fatty acid biosynthesis. It is over-expressed in many human

cancers, reported to be correlated with cancer growth, contributes to poor prognosis and inhibition of FAS results in decreased

cell proliferation, and loss of cell viability. Previously we have reported high expression not only in tissue, but also in serum in

patients with digestive cancers. Although FAS is found to be over-expressed in many solid tumors, its role in digestive cancer

has not been extensively evaluated. We have reported that it seems to be up-regulated during the early stages of tumorigenesis.

In Digestive neoplasm, Upper GI (esophageal and gastric) and colorectal ones have different characteristics due to carcino-

genesis. Upper GI neoplasm results from the continuous inflammation from Helicobacter pylori and various other factors.

Therefore colorectal one arises from adenoma carcinoma sequences. Our results show a different tendency for each other.

Compare between premalignant status and malignancy, by using serum and tumor FAS level we can approach the mechanism

of reprogramming the regulation of metabolic pathways.

Biography

Hajime Orita graduated and took the surgical training from Juntendo University School of medicine in Japan. Now he is the associate professor of dept. of upper GI

and especially do laparoscopic surgery. He had been post doctal studies and recived the adjunct associate professor degrer from Johns Hopkins University School

of medicine. He has published more than 10 papers in reputed journals and has been serving as an editorial board member of repute.
