Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 2,   Pages 179-183 doi: 10.1007/s11705-012-1273-6

Abstract: -Poly- -lysine ( -PL) is an -lysine linear homopolymer, which is produced by bacteria belonging to theIn most bacteria including the genus, -lysine is a precursor of -PL and is biosynthesized by theto improve -PL productivity, resistant mutants were produced using sulfaguanidine (SG) + glycine+ -lysineFinally, one -PL-producing strain, L9, was selected.The productivity of this strain during flask fermentation was 0.77 g/L, which was 15% higher than that

Acetylated HOXB9 at lysine 27 is of differential diagnostic value in patients with pancreatic ductal

Xiaoran Sun, Jiagui Song, Jing Zhang, Jun Zhan, Weigang Fang, Hongquan Zhang

Frontiers of Medicine 2020, Volume 14, Issue 1,   Pages 91-100 doi: 10.1007/s11684-019-0696-6

Abstract: Pancreatic ductal adenocarcinoma (PDAC) is the ninth most common human malignancy and the sixth leading cause of cancer-related death in China. AcK27-HOXB9 is a newly identified HOXB9 post-transcriptional modification that can predict the outcome in lung adenocarcinoma and colon cancer well. However, the role of AcK27-HOXB9 in PDAC is unclear. The present study aims to investigate the differential diagnostic role of patients with AcK27-HOXB9 PDAC. Tissue microarrays consisting of 162 pancreatic tumor tissue samples from patients with PDAC and paired normal subjects were used to examine HOXB9 and AcK27-HOXB9 levels and localizations by immunohistochemical analysis and Western blot assay, respectively. HOXB9 was upregulated ( <0.0001), and AcK27-HOXB9 ( =0.0023) was downregulated in patients with PDAC. HOXB9 promoted ( =0.0115), while AcK27-HOXB9 ( =0.0279) inhibited PDAC progression. AcK27-HOXB9 predicted favorable outcome in patients with PDAC ( =0.0412). AcK27-HOXB9 also suppressed PDAC cell migration in a cell migration assay. The results of this study showed that HOXB9 promoted and AcK27-HOXB9 suppressed PDAC progression. The determination of ratio between HOXB9 and AcK27-HOXB9 exhibited potential diagnostic value in patients with PDAC.
