Reprogramming tumor immune microenvironment by ultrasound‐responsive nanoplatforms for enhanced cancer immunotherapy

open access: yesBMEMat, EarlyView.
Ultrasound‐responsive nanoplatforms reprogram the tumor immune microenvironment by targeting tumor cells, immune cells, and non‐immune stromal cells to enhance the efficacy of cancer immunotherapy. Abstract Cancer immunotherapy represents a significant advancement in cancer treatment by enhancing the specific recognition and elimination of cancer cells.

A single nucleotide polymorphism produces different transcription profiles in Campylobacter jejuni’s cysM

open access: yesFrontiers in Microbiology
A single nucleotide polymorphism (SNP) in the 126 bp untranslated region (UTR) directly upstream of Campylobacter jejuni’s cysM (cysteine synthase) results in significant effects on gene transcription.

Dissecting the influence of Mg2+ on 3D architecture and ligand-binding of the guanine-sensing riboswitch aptamer domain [PDF]

open access: yes, 2010
Long-range tertiary interactions determine the three-dimensional structure of a number of metabolite-binding riboswitch RNA elements and were found to be important for their regulatory function. For the guanine-sensing riboswitch of the Bacillus subtilis

RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging

open access: yesBiological Reviews, EarlyView.
ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...

Guanine nucleotides regulate 2-[125I]Iodomelatonin binding sites in chick retinal pigment epithelium but not in neuronal retina

open access: yes, 1991
The characteristics of the binding sites labeled by the radioligand 2-[125I]iodomelatonin were compared in chicken neuronal retina and retinal pigment epithelium (RPE).

Membrane‐Permeable Nucleoside T‐1106 Diphosphate and Triphosphate Analogues as Antiviral Pronucleotides

open access: yesChemistry – A European Journal, EarlyView.
Favipiravir (T‐705) and the non‐fluorinated counterpart (T‐1106) are antiviral agents that inhibit the RNA‐dependent RNA polymerase (RdRp) of various RNA viruses. The antiviral efficacy of nucleoside analogues is strongly dependent on their intracellular activation by cellular kinases to produce their corresponding triphosphate metabolites (T‐705‐RTP ...

Influence of guanine nucleotides on complex formation between Ras and CDC25 proteins [PDF]

open access: yes, 1993
The Saccharomyces cerevisiae CDC25 gene and closely homologous genes in other eukaryotes encode guanine nucleotide exchange factors for Ras proteins. We have determined the minimal region of the budding yeast CDC25 gene capable of activity in vivo.
