Mesoporous Silica Nanoparticles With Customized Drug Ratio/Loading for Effective Treatment of Gemcitabine‐Resistant Pancreatic Tumors

open access: yesAdvanced NanoBiomed Research, EarlyView.
Redox responsive mesoporous silica nanoparticles (MSNs) were engineered to deliver gemcitabine (Gem) and cisplatin (cisPt) at defined ratios to overcome chemoresistance in pancreatic ductal adenocarcinoma (PDAC). Optimized Gem MSNs and Gem cisPt MSNs enhanced cytotoxicity in murine and human Gem resistant models, with select formulations inducing ...

Interaction of deoxycytidine and deoxycytidine analogs in normal and leukemic human myeloid progenitor cells

open access: yesLeukemia Research, 1986
The inhibitory effects of three deoxycytidine analogs, 1-B-D-arabinofuranosylcytosine (Ara-C), 5-aza-2'-deoxycytidine (DAZ) and Ara-5-azacytosine (AAC) were compared with respect to the clonogenic behavior of human promyelocytic leukemic cells (HL-60), a deoxycytidine kinase deficient subvariant (HL-60/Ara-C), and normal human myeloid progenitor cells (

Ribozymes for RNA‐Catalyzed RNA Methylation and Labeling

open access: yesAngewandte Chemie International Edition, EarlyView.
Ribozymes are powerful tools for site‐specific RNA modification. Their activities range from installing tags and fluorophores to generating natural RNA methylations, making them valuable tools to uncover the many functions that RNA plays in nature.

The Role of Different TET Proteins in Cytosine Demethylation Revealed by Mathematical Modeling

open access: yesEpigenomes
In living cells, some reactions can be conducted by more than one enzyme and sometimes it is difficult to establish which enzyme is responsible. Such is the case with proteins from the TET family, capable of converting 5-methyl-2’-deoxycytidine (5-mdC ...

Sjögren Disease—B Cells at the Brink: From Autoimmunity to Lymphomagenesis and the Rise of Novel B Cell–Targeted Therapies

open access: yesArthritis &Rheumatology, EarlyView.
Sjögren disease (SjD) is a common systemic autoimmune disorder characterized by inflammation of the exocrine glands, resulting in dryness. Patients frequently exhibit extraglandular manifestations affecting various organ systems. To date, there are no US Food and Drug Administration (FDA)‐approved disease‐modifying therapies for SjD. In this review, we
