HDAC6 and USP9X Control Glutamine Metabolism by Stabilizing GS to Promote Glioblastoma Tumorigenesis

open access: yesAdvanced Science, EarlyView.
Glioblastoma (GBM) growth relies on glutamine synthetase (GS), which is stabilized by histone deacetylase 6 (HDAC6) and deubiquitinated by ubiquitin‐specific peptidase 9, X‐linked (USP9X). HDAC6 promotes GS deacetylation, while USP9X removes its K48‐linked polyubiquitination, enhancing GS stability.

A Self-Assembled Aggregate Composed of a Fatty Acid Membrane and the Building Blocks of Biological Polymers Provides a First Step in the Emergence of Protocells

open access: yesLife, 2016
We propose that the first step in the origin of cellular life on Earth was the self-assembly of fatty acids with the building blocks of RNA and protein, resulting in a stable aggregate.

Role of Nucleoside Transporters in Nucleoside-Derived Drug Sensitivity

open access: yesNucleosides, Nucleotides and Nucleic Acids, 2010
Nucleoside-derived drugs are currently used clinically as anticancer drugs. To exert their pharmacological action first they need to enter into the cell across plasma membrane transporters and be metabolized. Thus, efficacy of treatment and acquisition of resistance can rely on a variety of events.

Therapeutic Potential of Lipid Nanoparticle‐Encapsulated CD19‐Targeting mRNAs in Lupus and Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
This study develops lipid nanoparticle‐encapsulated mRNA‐encoding antibodies (mRNab‐LNPs) targeting CD19, demonstrating robust anti‐CD19 antibody production in vivo. Intramuscular injection of mRNab‐LNPs reduces CD19+ B and plasma cells in lupus and rheumatoid arthritis mice, significantly alleviating histopathological changes and tissue injuries of ...

A cytotoxic survey on 2‐amino‐1H‐imidazol based synthetic marine sponge alkaloid analogues

open access: yesDrug Development Research, Volume 83, Issue 8, Page 1906-1922, December 2022., 2022
Abstract Here, we describe the synthesis and biologic activity evaluation of 20 novel synthetic marine sponge alkaloid analogues with 2‐amino‐1H‐imidazol (2‐AI) core. Cytotoxicity was tested on murine 4T1 breast cancer, A549 human lung cancer, and HL‐60 human myeloid leukemia cells by the resazurin assay.

Marine Nucleosides: Structure, Bioactivity, Synthesis and Biosynthesis

open access: yesMarine Drugs, 2014
Nucleosides are glycosylamines that structurally form part of nucleotide molecules, the building block of DNA and RNA. Both nucleosides and nucleotides are vital components of all living cells and involved in several key biological processes.

Kinetic analysis of an efficient DNA-dependent TNA polymerase. [PDF]

open access: yes, 2005
alpha-l-Threofuranosyl nucleoside triphosphates (tNTPs) are tetrafuranose nucleoside derivatives and potential progenitors of present-day beta-d-2'-deoxyribofuranosyl nucleoside triphosphates (dNTPs).

HPLC reveals novel features of nucleoside and nucleobase homeostasis, nucleoside metabolism and nucleoside transport

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2020
Humans possess three members of the cation-coupled concentrative nucleoside transporter CNT (SLC 28) family, hCNT1-3: hCNT1 is selective for pyrimidine nucleosides but also transports adenosine, hCNT2 transports purine nucleosides and uridine, and hCNT3 transports both pyrimidine and purine nucleosides.

Cladribine Analogues via O6-(Benzotriazolyl) Derivatives of Guanine Nucleosides

open access: yesMolecules, 2015
Cladribine, 2-chloro-2′-deoxyadenosine, is a highly efficacious, clinically used nucleoside for the treatment of hairy cell leukemia. It is also being evaluated against other lymphoid malignancies and has been a molecule of interest for well over half a ...
