Inhibition of SIRT7 Overcomes Radioresistance in Pancreatic Neuroendocrine Tumors by Reactivating MEN1 Expression

Advanced Science, EarlyView.
Pancreatic neuroendocrine tumors frequently silence MEN1 through epigenetic mechanisms. Here, SIRT7 recruits DNMT1 to the MEN1 promoter, drives hypermethylation, and enhances DNA repair. Inhibiting SIRT7 restores MEN1, reduces MRN complex abundance, impairs double‐strand break repair, and sensitizes PanNET models to radiation, supporting SIRT7 as a ...

Theoretical insights into the interaction of 6-Thioguanine anticancer drug with β-Cyclodextrin as a pharmaceutical Nanocarrier via density functional theory

Results in Chemistry
In this study, the absorption and interaction effects of the anticancer drug 6-Thioguanine in various orientations on the β-cyclodextrin nanocarrier were theoretically investigated and optimized using Gaussian 09 software. Quantum mechanical calculations,

Unveiling the photophysics of thiourea from CASPT2/CASSCF potential energy surfaces and singlet/triplet excited state molecular dynamics simulations

, 2019
This work describes the decay mechanism of photoexcited thiourea, both in gas phase and in solution, from the information inferred from the topography of the excited and ground state potential energy surfaces and mixed singlet/triplet quantum classical ...

Construction of a MOF‐Based Snap‐Top Delivery Nanosystem for Powerful Dual‐Responsive Synergistic Colitis Treatment

Advanced Science, EarlyView.
A snap‐top delivery nanosystem based on an azobenzene metal–organic framework achieves targeted release of 6‐mercaptopurine via acid‐stable frameworks and hypoxia/pH dual‐responsive β‐cyclodextrin gates. This multifunctional platform integrates three synergistic mechanisms: precision drug delivery to inflammatory sites, intrinsic antioxidant properties

Oral vancomycin solution is superior to capsule in inducing clinical biomarker and endoscopic remission in children with atypical ulcerative colitis

British Journal of Clinical Pharmacology, EarlyView.
Aims Atypical colitis (presenting reverse gradient colitis, backwash ileitis or rectal sparing) is associated with primary sclerosing cholangitis–ulcerative colitis (PSC). Oral vancomycin has been used to manage paediatric atypical colitis with/without confirmed PSC. Different preparations had shown different efficacy.

Effect of developmental changes on pharmacokinetics of drugs used in the treatment of infant acute lymphoblastic leukaemia—A comprehensive review

British Journal of Clinical Pharmacology, EarlyView.
While the event‐free survival (EFS) of children treated for acute lymphoblastic leukaemia (ALL) has improved greatly in the last decades, the EFS for patients diagnosed with ALL before the age of one is still under 50%. This outcome further decreases when infants have a rearrangement in the gene encoding histone‐lysine N‐methyltransferase 2A (KMT2A ...

The decline of 6‐thioguanine nucleotides is not linked to impaired efficacy or safety of thiopurines in pregnant women with inflammatory bowel disease

British Journal of Clinical Pharmacology, EarlyView.
Background Thiopurines are used to maintain remission in inflammatory bowel disease (IBD). These drugs are metabolized into 6‐thioguanine nucleotides (6‐TGN), associated with efficacy, and 6‐methylmercaptopurine ribonucleotides (6‐MMPR), associated with adverse drug reactions. Pregnancy has been linked to a shift in thiopurine metabolism, characterized
