This study explores the origins of life by linking prebiotic chemistry, the emergence of information‐carrying molecules such as RNA and proteins, and philosophical questions about consciousness. The study emphasizes the role of molecular evolution in the Central Dogma and provides insights into the chemical origins of biology and the basis of life's ...

Small‐Molecule Activation of mRNA Translation by Click‐to‐Release Reaction in Cells
A new method to control mRNA activity using bioorthogonal click‐to‐release reactions is presented. The 5′ cap is modified with a trans‐cyclooctene (TCO) that quickly reacts with hydroxyaryl‐tetrazines and efficiently releases the native cap 0. TCO‐capped mRNAs are initially translationally inactive but can be activated with non‐toxic, cell‐permeable ...

Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Two kinds of self‐assembled RNA micelles were used to co‐deliver synergistic siRNA and nucleoside analogues for the treatment of colorectal cancer lung metastases. Near‐complete elimination of lung cancer metastases was confirmed in an orthotopic lung metastasis model constructed using human colorectal cancer lung metastases patient surgical samples to

Discovery that deadenylation, rather than transcription, acts as the rate‐limiting step for developmental timing in a plant pathogen. Evidence that P‐body integrity and mRNA decay are mechanistically coupled to rapid cellular differentiation under environmental stress. Identification of Pan2‐Pan3 as a pathogen‐specific “meta‐virulence factor” absent in

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

ProTides for Antiviral Activity Beyond Liver Cells
A strategy for obtaining prodrugs of antiviral nucleotides with broad tissue activity is presented that relies on cycloalkyl or cycloalkylalkyl esters, improving uptake and esterase cleavage, and producing nanomolar inhibitors in kidney, colon, and lung cells.

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to
