چکیده

Under the endoscopic observation with magnification endoscopy and narrow-band imaging, one of the novel findings in gastric neoplasms is white opaque substance (WOS), which is a manifestation of intracellular accumulation of lipid droplets. To elucidate the significance of this WOS formation, detailed lipid metabolism should be understood in gastric membranes. Recently, expression profiles of lipid-metabolism-associated genes in gastric tumor and non-tumor mucosa were investigated and reported. In this article, we explain the lipid accumulation and disturbance of lipid metabolism in gastric neoplasms.

Lipid is absorbed in the stomach by epithelial neoplasms (adenomas and early cancers): a novel functional endoscopy technique

BACKGROUND AND STUDY AIMS The authors have successfully demonstrated that the white opaque substance (WOS) identified in gastric epithelial neoplasms is an accumulation of minute lipid droplets on the epithelial neoplasm. It is not known whether the lipid droplets originate from externally ingested lipids (typically foods). The purpose of this study was to investigate whether the oral ingestion...

Histologic differentiation and mucin phenotype in white opaque substance-positive gastric neoplasias

BACKGROUND AND STUDY AIMS The authors previously reported that the white opaque substance (WOS) in gastric epithelial neoplasia was caused by accumulation of lipid droplets by immunohistochemical and immunoelectron microscopic studies of adipophilin, which was recently identified and validated as a marker of lipid droplets. The aim of the current study was to investigate the characteristics of ...

5-Year Survival in Gastric Adenocarcinoma with Epithelial and Stromal Versican Expression

Background & Objective: Gastric cancer is the second most frequent cause of cancer death worldwide, despite differences in incidence around the world. The majority of gastric cancer cases concern gastric adenocarcinoma, which has a fairly high 5-year survival rate when coupled with early-stage diagnosis. Versican, a member of the aggregating chondroitin sulfate proteoglycans fa...

Lipid droplet growth by fusion: insights from freeze-fracture imaging

An understanding of how lipid droplets grow in the cell is important to current human health issues. Homotypic fusion of small lipid droplets to create larger ones is one proposed mechanism though the evidence for this process continues to be debated. By applying the technique of freeze-fracture electron microscopy to cells that have been stimulated to accumulate lipid droplets, we here present...

Fat on the move: intracellular motion of lipid droplets.

Lipid droplets are intracellular organelles that play central roles in lipid metabolism. In many cells, lipid droplets undergo active motion, typically along microtubules. This motion has been proposed to aid growth and breakdown of droplets, to allow net transfer of nutrients from sites of synthesis to sites of need and to deliver proteins and lipophilic signals. This review summarizes the cur...
