Aerobic prokaryotes do not have higher GC contents than anaerobic prokaryotes, but obligate aerobic prokaryotes have

BMC Evolutionary Biology, 2019
Background Among the four bases, guanine is the most susceptible to damage from oxidative stress. Replication of DNA containing damaged guanines results in G to T mutations.

DNA Flap‐Mediated Control of Transcription for Programmable RNA Synthesis

Angewandte Chemie International Edition, EarlyView.
Pyrimidine‐rich ssDNA flaps on the T7 promoter inhibit T7 RNA polymerase (T7RP) transcription. Leveraging this pyrimidine bias, we developed DNAzyme‐ and MNAzyme‐mediated flap promoter induced transcription control (D‐FIT and M‐FIT) systems. These platforms enable regulated transcription and sequence‐specific detection, highlighting the programmable ...

Controlled Delivery and Light‐Induced Release of Magic Spot Nucleotides in Escherichia coli

Angewandte Chemie International Edition, EarlyView.
We synthesized photocaged, clickable and isotope‐labeled “magic spot” Nucleotides and delivered them into Escherichia coli comparing different approaches. Light‐controlled release inside living cells enabled tracking of their conversion from pppGpp to ppGpp by capillary electrophoresis mass spectrometry and revealed their impact on the growth rate of a

Change in Nutritional Status Modulates the Abundance of Critical Pre-initiation Intermediate Complexes During Translation Initiation \u3cem\u3ein Vivo\u3c/em\u3e [PDF]

, 2007
In eukaryotic translation initiation, eIF2∙GTP–Met-tRNAiMet ternary complex (TC) interacts with eIF3–eIF1–eIF5 complex to form the multifactor complex (MFC), while eIF2∙GDP associates with eIF2B for guanine nucleotide exchange.

Effect of defects on thermal denaturation of DNA Oligomers

, 2001
The effect of defects on the melting profile of short heterogeneous DNA chains are calculated using the Peyrard-Bishop Hamiltonian. The on-site potential on a defect site is represented by a potential which has only the short-range repulsion and the flat

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 ...

Nanomaterial‐based immune therapeutic strategies in neurodegenerative diseases

BMEMat, EarlyView.
This review highlights the immunomodulatory potential of nanomaterials (NMs) in treating neurodegenerative diseases (NDs). It focuses on their roles in regulating innate and adaptive immune responses to maintain immune homeostasis. By providing insights into these mechanisms, the review lays the groundwork for innovative NMs therapeutic strategies to ...

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

BMEMat, 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.

Assignments of backbone 1H, 13C and 15N resonances in H-Ras (1–166) complexed with GppNHp at physiological pH [PDF]

, 2012
The small GTPase Ras is an important signaling molecule acting as a molecular switch in eukaryotic cells. Recent findings of global conformational exchange and a putative allosteric binding site in the G domain of Ras opened an avenue to understanding ...

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...
