Early relapse on adjuvant gemcitabine associated with an exceptional response to 2nd line capecitabine chemotherapy in a patient with pancreatic adenosquamous carcinoma with strong intra-tumoural expression of cytidine deaminase: a case report

BMC Cancer, 2020
Background Pancreatic adenosquamous carcinoma has a poor prognosis, with limited prospective trial data to guide optimal treatment. The potential impact of drug metabolism on the treatment response of patients with pancreatic adenosquamous carcinoma is ...

Cytidine triphosphate:phosphatidic acid cytidyltransferase in Escherichia coli

Journal of Lipid Research, 1968
An enzyme has been found in particulate fractions of Escherichia coli that catalyzes the incorporation of cytidine triphosphate (CTP) into lipid in the presence of exogenous phosphatidic acid and Mg++. The product has been identified enzymatically and by

Resistance of Cyclocytidine to Cytidine Deaminase

Chemical and Pharmaceutical Bulletin, 1973
Deamination of cytidine derivatives especially of cyclocytidine by mouse kidney cytidine deaminase was examined. Cyclocytidine was not deaminated at either pH6.5 or pH7.3 by the enzyme. Furthermore, cyclocytidine did not inhibit the deamination of aracytidine and ([I]/[S])0.5 value for cyclocytidine was over 100.

Double-strand break-free and transgene-free genome editing in the microalga Nannochloropsis oceanica using removable vectors containing the CRISPR base editing system

Scientific Reports
The accumulation of lipids by algae makes them attractive for carbon-neutral fuel production; however, the industrial-scale production of algal lipids has yet to be achieved.

Synthesis of ethanolamine phosphoglycerides by human platelets.

Journal of Lipid Research, 1975
Platelet homogenates contain an ethanolaminephosphotransferase (EC 2.7.8.1) that catalyzes the synthesis of ethanolamine phosphoglycerides from cytidine-5‘-diphosphate ethanolamine and 1-radyl-2-acyl-sn-glycerols.

Pharmacogenomic profiling of the efficacy of gemcitabine monotherapy in metastatic pancreatic cancer: Subgroup analysis of the GENESECT study

British Journal of Clinical Pharmacology, EarlyView.
Aim In the GENESECT study, no significant gemcitabine (GEM) metabolism‐related germline genetic polymorphisms (GPs) were identified because approximately 70% of patients received combination therapy with nab‐paclitaxel, which has metabolic pathways different from GEM.

Phosphonomethyl (Thio)Phosphonamidite Reagents for the Construction of Phosphonylmethyl Phosphono(Di)Thioate Mono‐ and Diesters

Chemistry – A European Journal, EarlyView.
A set of new phosphonomethyl (thio)phosphonamidite reagents is introduced to generate unprecedented pyrophosphate mimetics. The versatile P(III)‐P(V) reagents allow for the construction of various pyrophosphate isosteres, and the applicability of the chemistry is illustrated in the assembly of a diverse set of stabilized CDP‐glycerol and CDP‐ribitol ...
