Transcription start site scanning and the requirement for ATP during transcription initiation by RNA polymerase II [PDF]
, 2016 Saccharomyces cerevisiae RNA polymerase (Pol) II locates transcription start sites (TSS) at TATA-containing promoters by scanning sequences downstream from the site of preinitiation complex formation, a process that involves the translocation of ...

Advanced Science, EarlyView.Plasmonic molecular entrapment (PME) is label‐free detection and quantification method for DNA methylation. This technique provides direct hotspot site generation around target analytes, overcoming mismatch geometrical properties. The PME demonstrates superior SERS performance and quantification capability, offering promising potential for epigenetic ...

Multi‐Omics and ‐Organ Insights into Energy Metabolic Adaptations in Early Sepsis Onset
Advanced Science, EarlyView.This study shows that patients at risk of sepsis have a distinct metabolite and lipid signature, including serine and aminoadipic acid, in their serum before clinical diagnosis. A mouse model of sepsis with a compatible serum signature reveals underlying metabolic changes, including mitochondrial adaptation, altered serine‐dependent purine metabolism ...

AMP-activated protein kinase – not just an energy sensor [version 1; referees: 3 approved]
F1000Research, 2017 Orthologues of AMP-activated protein kinase (AMPK) occur in essentially all eukaryotes as heterotrimeric complexes comprising catalytic α subunits and regulatory β and γ subunits.

Characterizing large scale base composition structures of genomes [PDF]
arXiv, 2004 Intermittent density fluctuations of nucleotide molecules (adenine, guanine, cytosine and thymine) along DNA sequences are studied in the framework of a hierarchical structure (HS) model originally proposed for the study of fully developed turbulence [She and Leque, Phys. Rev. Lett. 72}, 336 (1994)].

Hydrogel‐Based Smart Materials for Wound Healing and Sensing
Aggregate, EarlyView.The graphical abstract illustrates the role of hydrogel‐based flexible materials in advancing biomedical applications, including wound healing, point‐of‐care diagnostics, smart patches, and wearable devices. Hydrogels are particularly promising in modern wound care due to their high‐water content, flexibility, and biocompatibility.

Two-dimensional chemical mapping for non-coding RNAs [PDF]
arXiv, 2011 Non-coding RNA molecules fold into precise base pairing patterns to carry out critical roles in genetic regulation and protein synthesis. We show here that coupling systematic mutagenesis with high-throughput SHAPE chemical mapping enables accurate base pair inference of domains from ribosomal RNA, ribozymes, and riboswitches.
