AVI may be protein matrix and it possesses neither a membrane boundary nor an internal structure,its formation is the result of the anthocyanins transported into the vacuole bind with a protein matrix. In vacuole, AVI is irregular and jelly-like in shape. In AVIs, the attachment of anthocyanins to the matrix protein is likely to be via H-bonds to a sterically restricted site. AVI is suggested to act as vacuolar anthocyanin "trap", preferentially for anthocyanidin 3, 5-diglycosides or acylted anthocyanins. The emergence of AVI can enhance color intensity and results in the "blueness" of color in the vacuole.

花色苷液泡包涵体可能具备蛋白质基质，既无膜包裹又无内部结构，其形成是转运进液泡的花色苷与蛋白质基质结合的结果；液泡里的花色苷液泡包涵体形状不规则，象果冻；在花色苷液泡包涵体中，花色苷可能通过氢键连接于蛋白质基质的一个有限空间位点；花色苷液泡包涵体被认为是液泡中花色苷的&陷阱&，优先摄取花色素3，5-二糖苷或酰化的花色苷；花色苷液泡包涵体的存在可增加液泡色彩的强度并导致&蓝化&。

In order to explore the extraction method of proteome and technique of 2-DE, we compared the extraction method between the TCA-ac-tone and the Tris-HCl, and improved the key steps of 2-DE. The Tris-HCl extraction was the most appropriate for Antiaris toxicaria seed proteome analysis because of the highest resolution and more informative 2-DE map. Those were the solid basis for the later research of studying on the discrepancy expression proteomics of Antiaris toxicaria Seed.

RESULTS: A well-resolved and reproducible 2-DE pattern of PBMC was obtained from patients with HBV associated HCC or LC. For HCC, the mean number of protein spots was 1186±43, with an average matching rate of 91.6%, and for LC, the mean number of protein spots was 1013±41, with an average matching rate of 90.2%. Twenty-seven differential proteins were tested by MALDI-TOFMS, and 16 were identified. Of the 16 proteins, 13 were up-regulated in patients with HCC, including heat-shock protein 27, member RAS oncogene family (RAB14), actin, alpha 1 antitrypsin, RNAbinding protein regulatory subunit and so on. By contrast, the levels of proteins such as PDX6, HSPA8 and MnSOD were significantly reduced in HCC patients.
