MMA is produced by the method of acetone-cyanhydrin mainly in our country. The synthetic route is complex, the technical line is long, and the yield is low with high cost after many steps. Hydrocyanic acid is used as raw material, the treatment of numerous waste acid is difficult . Furthermore, concentrated sulfuric acid consumed in this method corrodes equipments and pollutes the environment seriously.

我国MMA的生产以丙酮腈醇法占主导地位，合成路线复杂，生产工艺长，多步反应后产率低，成本高，其采用有剧毒的氢氰酸为原料，产生大量难于处理的废酸，所消耗的浓硫酸对设备腐蚀性大，对环境污染严重，因此开发新的MMA工艺路线很有必要。

Methacrylic Acid is one of the most important organic materials, and there is large demand indomestic and international market. The traditional preparation method of MAA has lots of limitation suchas high cost, huge pollution, and virulent raw materials. So its necessary to search a new green route toreplace the ACH route.

甲基丙烯酸是一种重要的有机化工原料，目前国内外对MAA的需求量很大，而传统的丙酮氰醇法制备MAA存在成本高、环境污染大、原料剧毒等缺点，所以需要寻找一条新的绿色工艺路线代替传统工艺。

SW480 and SW620 cells were also used to study the gene regulation with high carbohydrate intake, where it was shown that during glycolysis eight genes, HK1 (nuclear gene encoding mitochondrial protein, transcript variant 1), GPI, GAPD (glyceraldehyde-3-phosphate dehydrogenase), PGK1 (phosphoglycerate kinase 1), PGK2 (phosphoglycerate kinase 2), ENO2 (enolase 2), PKM2 (pyruvate kinase, muscle, transcript variant 2) and GLUT1 (facilitated glucose transporter, member 1) are over-expressed. In our study, we also found that during hypoxia of cancer tissues the resulting up-regulation of HIF-2α(hypoxia-inducible factor 2, alpha subunit) would in turn up-regulate the GLU1 gene, further activating glycolysis.
