Defects in long-chain 3-hydroxy acyl-CoA dehydrogenase lead to hepatocellular carcinoma: A novel etiology of hepatocellular carcinoma. Int J Cancer 2020; 147:1461-1473. [PMID: 32115688 DOI: 10.1002/ijc.32943] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2019] [Revised: 01/02/2020] [Accepted: 02/17/2020] [Indexed: 12/14/2022]
Abstract
The incidence of both nonalcoholic fatty liver disease (NAFLD) and hepatocellular carcinoma (HCC) have been increasing at an alarming rate. Little is known about NAFLD without cirrhosis as a risk for HCC. Here we report, for the first time, generation of a mouse model with a defect in long-chain 3-hydoxy acyl-CoA dehydrogenase (LCHAD). The LCHAD exon 15 deletion was embryonic lethal to the homozygous mice whereas heterozygous mice (HT) develop significant hepatic steatosis starting at young age (3 months old) and HCC at older age (>13 months old) without any evidence of fibrosis or cirrhosis. None of the wild-type (WT) mice developed steatosis and HCC (n = 39), whereas HT-LCHAD mice (n = 41) showed steatosis and ~20% (8/41) developed liver masses with histological features of HCC. Proteomic analysis of liver tissues from WT-mice and HT-mice with no signs of HCC was conducted. Proteins with significant changes in abundance were identified by mass spectrometry. Abundance of 24 proteins was significantly different (p < 0.01) between WT and HT-LCHAD mice. The proteins found to vary in abundance are associated with different cellular response processes ranging from intermediary metabolism of carbohydrate, protein and lipid to oxidative stress, signal transduction and the process of tumorigenesis. Protein expression pattern of the HT-LCHAD mouse liver indicates predisposition to HCC and suggests that impaired hepatic mitochondrial fatty acid oxidation plays an important role in the development and progression of HCC. To assess the implication of these studies in human disease, we demonstrated significant downregulation of HADHA transcripts in HCC patients.

Ye JS, Liu J, Ou HS, Wang LL. Degradation of ciprofloxacin by 280 nm ultraviolet-activated persulfate: Degradation pathway and intermediate impact on proteome of Escherichia coli. CHEMOSPHERE 2016; 165:311-319. [PMID: 27664520 DOI: 10.1016/j.chemosphere.2016.09.031] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/08/2016] [Revised: 09/08/2016] [Accepted: 09/08/2016] [Indexed: 06/06/2023]
Abstract
In this study, the degradation of ciprofloxacin (CIP) was explored using ultraviolet activated persulfate (UV/PS) with 280 nm ultraviolet light-emitting diodes (UV-LEDs), and the toxicological assessment of degrading intermediates was performed using iTRAQ labeling quantitative proteomic technology. The quantitative mass spectrum results showed that 280 nm UV/PS treatment had a high transformation efficiency of CIP ([CIP] = 3 μM, [S2O82-] = 210 μM, apparent rate constants 0.2413 min-1). The high resolution mass spectrum analyses demonstrated that the primary intermediates included C15H16FN3O3 (m/z 306.1248) and C17H18FN3O4 (m/z 348.1354). The former one was formed by the cleavage of piperazine ring, while the later one was generated by the addition of a hydroxyl on the quinolone backbone. The toxicological assessment demonstrated that 56 and 110 proteins had significant up regulations and down regulations, respectively, in the Escherichia coli exposed to degraded CIP compared to untreated CIP. The majority of up-regulated proteins, such as GapA, SodC, were associated with primary metabolic process rather than responses to stress and toxic substance, inferring that the moderate UV/PS treatment can reduce the antibacterial activity of CIP by incomplete mineralization. Consequently, these results provided a novel insight into the application of UV-LED/PS treatment as a promising removal methodology for quinolones.
