| 2 | Post-translational modifications of prostaglandin-endoperoxide synthase 2 in colorectal cancer:An update显示文摘The biosynthesis of prostanoids is involved in both physiological and pathological processes. The expression of prostaglandin-endoperoxide synthase 2(PTGS2; also known as COX-2) has been traditionally associated to the onset of several pathologies, from inflammation to cardiovascular, gastrointestinal and oncologic events. For this reason, the search of selective PTGS2 inhibitors has been a focus for therapeutic interventions. In addition to the classic non-steroidal anti-inflammatory drugs, selective and specific PTGS2 inhibitors, termed coxibs, have been generated and widely used. PTGS2 activity is less restrictive in terms of substrate specificity than the homeostatic counterpart PTGS1, and it accounts for the elevated prostanoid synthesis that accompanies several pathologies. The main regulation of PTGS2 occurs at the transcription level. In addition to this, the stability of the mRNA is finely regulated through the interaction with several cytoplasmic elements, ranging from specificmicroR NAs to proteins that control mR NA degradation. Moreover, the protein has been recognized to be the substrate for several post-translational modifications that affect both the enzyme activity and the targeting for degradation via proteasomal and non-proteasomal mechanisms. Among these modifications, phosphorylation, glycosylation and covalent modifications by reactive lipidic intermediates and by free radicals associated to the proinflammatory condition appear to be the main changes. Identification of these post-translational modifications is relevant to better understand the role of PTGS2 in several pathologies and to establish a correct analysis of the potential function of this protein in diseases progress. Finally, these modifications can be used as biomarkers to establish correlations with other parameters, including the immunomodulation dependent on molecular pathological epidemiology determinants, which may provide a better frame for potential therapeutic interventions. | Rafael I Jaén Patricia Prieto Marta Casado Paloma Martín-Sanz Lisardo Boscá | 2018 | World Journal of Gastroenterology2018，24，48： | 5 |
| 3 | Interplay between post-translational cyclooxygenase-2 modifications and the metabolic and proteomic profile in a colorectal cancer cohort显示文摘BACKGROUND Colorectal cancer(CRC) is the second most common cause of cancer death worldwide. It is broadly described that cyclooxygenase-2(COX-2) is mainly overexpressed in CRC but less is known regarding post-translational modifications of this enzyme that may regulate its activity, intracellular localization and stability. Since metabolic and proteomic profile analysis is essential for cancer prognosis and diagnosis, our hypothesis is that the analysis of correlations between these specific parameters and COX-2 state in tumors of a high number of CRC patients could be useful for the understanding of the basis of this cancer in humans.AIM To analyze COX-2 regulation in colorectal cancer and to perform a detailed analysis of their metabolic and proteomic profile.METHODS Biopsies from both healthy and pathological colorectal tissues were taken under informed consent from patients during standard colonoscopy procedure in the University Hospital of Bellvitge(Barcelona, Spain) and Germans Trias i Pujol University Hospital(Campus Can Ruti)(Barcelona, Spain). Western blot analysis was used to determine COX-2 levels. Deglycosylation assays were performed in both cells and tumor samples incubating each sample with peptide N-glycosidase F(PNGase F). Prostaglandin E2(PGE2) levels were determined using a specific ELISA. 1 H high resolution magic angle spinning(HRMAS) analysis was performed using a Bruker AVIII 500 MHz spectrometer and proteomic analysis was performed in a nano-liquid chromatography-tandem mass spectrometer(nano LC-MS/MS) using a QExactive HF orbitrap MS.RESULTS Our data show that COX-2 has a differential expression profile in tumor tissue of CRC patients vs the adjacent non-tumor area, which correspond to a glycosylated and less active state of the protein. This fact was associated to a lesser PGE2 production in tumors. These results were corroborated in vitro performing deglycosylation assays in HT29 cell line where COX-2 protein profile was modified after PNGase F incubation, showing higher PGE2 levels. Moreover,HRMAS analysis indicated that tumor tissue has altered metabolic features vs non-tumor counterparts, presenting increased levels of certain metabolites such as taurine and phosphocholine and lower levels of lactate. In proteomic experiments, we detected an enlarged number of proteins in tumors that are mainly implicated in basic biological functions like mitochondrial activity,DNA/RNA processing, vesicular trafficking, metabolism, cytoskeleton and splicing.CONCLUSION In our colorectal cancer cohort, tumor tissue presents a differential COX-2 expression pattern with lower enzymatic activity that can be related to an altered metabolic and proteomic profile. | Patricia Prieto Rafael I Jaén Daniel Calle María Gómez-Serrano Estefanía Nú?ez María Fernández-Velasco Paloma Martín-Sanz Sergio Alonso Jesús Vázquez Sebastián Cerdán Miguel ángel Peinado Lisardo Boscá | 2019 | World Journal of Gastroenterology2019，25，4： | 4 |

| 11 | From conventional two-stage hepatectomy to ALPPS:Fifteen years of experience in a hepatobiliary surgery unit显示文摘Background:Hepatectomy in patients with large tumor load may result in postoperative liver failure and associated complications due to excessive liver parenchyma removal.Conventional two-stage hepatectomy(TSH)and associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)technique are possible solutions to this problem.Colorectal liver metastases(CRLM)is the most frequent indication,and there is a need to assess outcomes for both techniques to improve surgical and long-term oncological outcomes in these patients.Methods:A single-center retrospective study was designed to compare TSH with ALPPS in patients with initially unresectable bilateral liver tumors between January 2005 and January 2020.ALPPS was performed from January 2012 onwards as the technique of choice.Long-term overall survival(OS)and disease-free survival(DFS)were evaluated as primary outcome in CRLM patients.Postoperative morbidity,mortality and liver growth in all patients were also evaluated.Results:A total of 38 staged hepatectomies were performed:17 TSH and 21 ALPPS.Complete resection rate was 76.5%(n=13)in the TSH group and 85.7%(n=18)in the ALPPS group(P=0.426).Overall major morbidity(Clavien-Dindo≥3 a)(stage 1+stage 2)was 41.2%(n=7)in TSH and 33.3%(n=7)in ALPPS patients(P=0.389),and perioperative 90-day mortalities were 11.8%(n=2)vs.19.0%(n=4)in each group,respectively(P=0.654).Intention-to-treat OS rates at 1 and 5 years in CRLM patients for TSH(n=15)were 80%and 33%,and for ALPPS(n=17)76%and 35%,respectively.DFS rates at 1 and 5 years were 36%and 27%in the TSH group vs.33%and 27%in the ALPPS group,respectively.Conclusions:ALPPS is an effective alternative to TSH in bilateral affecting liver tumors,allowing higher resection rate,but patients must be carefully selected.In CRLM patients similar long-term OS and DFS can be achieved with both techniques. | Javier Maupoey Ibáñez Eva María MontalváOrón Andrea BoscàRobledo Alonso Camacho Ramírez Ana Hernando Sanz Pablo Granero Castro Alberto Alegre Delgado Rafael López-Andújar | 2021 | Hepatobiliary & Pancreatic Diseases International2021，20，6： | 0 |
| 12 | Methotrexate induced sprue-like syndrome显示文摘A 52 year-old male patient diagnosed of ankylosing spon-dylitis presented with an iron deficiency anemia after a ten-month treatment of methotrexate. He did not respond to treatment with oral iron not a proton pump inhibitor and an upper endoscopy was performed. The histological study of the duodenal biopsies showed villus atrophy. After removing the methotrexate, administrating intra-muscular iron and undertaking a gluten-free diet, the histological and analytical alterations progressively resolved. | Marta Maia Boscá Ramon Aón Rosana Villagrasa Nelly Balza Cirilo Amorós Adolfo Benages Empar Mayordomo Juan Ramon Corts | 2008 | World Journal of Gastroenterology2008，14，45： | 0 |
