Transient disappearance of RAS mutant clones in plasma: A counterintuitive clinical use of EGFR inhibitors in RAS mutant metastatic colorectal cancer [PDF]

open access: yes, 2019
Genomic studies performed through liquid biopsies widely elucidated the evolutionary trajectory of RAS mutant clones under the selective pressure of EGFR inhibitors in patients with wild type RAS primary colorectal tumors. Similarly, the disappearance of

Glucocorticoids and the regulation of phosphoenolpyruvate carboxykinase (guanosine triphosphate) in the rat [PDF]

open access: yesBiochemical Journal, 1975
The effect glucocorticoids on the synthesis and degradation of phosphoenolpyruvate carboxykinase (GTP)(EC4.1.1.32) in rat liver and kidney in vivo was studied immunochemically. The glucocorticoid analogue triamcinolone (9α-fluoro-11β, 21-dihydroxy-16α,17α-isopropylidenedioxypregna-1,4-diene-3,20-dione) increased the synthesis rate of the kidney enzyme ...

The synthesis of 2′-methylseleno adenosine and guanosine 5′-triphosphates

open access: yesBioorganic & Medicinal Chemistry, 2012
Modified nucleoside triphosphates (NTPs) represent powerful building blocks to generate nucleic acids with novel properties by enzymatic synthesis. We have recently demonstrated the access to 2'-SeCH(3)-uridine and 2'-SeCH(3)-cytidine derivatized RNAs for applications in RNA crystallography, using the corresponding nucleoside triphosphates and distinct
