Calculation of absolute free energy of binding for theophylline and its analogs to RNA aptamer using nonequilibrium work values

open access: yes, 2007
The massively parallel computation of absolute binding free energy with a well-equilibrated system (MP-CAFEE) has been developed [H. Fujitani, Y. Tanida, M. Ito, G. Jayachandran, C. D. Snow, M. R. Shirts, E. J. Sorin, and V. S. Pande, J. Chem.

Aptamers and Cancer

open access: yesAsian Pacific Journal of Cancer Biology, 2016
Oligonucleotides Aptamers are single strands of DNA and RNA with the length of 20-100 nucleotides or peptides and unique three dimensional structure that is affected by nucleotide sequence. The structure exclusively influences aptamers’ bindings with its target molecule.

DNA‐Guided Robust Single‐Protein Electronic Readout

open access: yesAdvanced Science, EarlyView.
Electronic measurements of single proteins can reveal fundamental insights into their structure, dynamics, and interactions, but reproducibility is severely limited by the intrinsic structural heterogeneity of proteins combined with uncontrolled molecular orientation and electrode contact geometries.

MARPLE: A Proximity‐Triggered CRISPR‐Cas13 Platform for Ultrasensitive Antibody Detection

open access: yesAdvanced Science, EarlyView.
MARPLE is a modular CRISPR‐Cas13 immunoassay that uses antibody‐induced proximity to trigger a toehold‐exchange reaction, releasing an RNA activator for Cas13. This one‐pot, isothermal architecture enables ultrasensitive (femtomolar) and highly specific detection of diverse antibodies, including therapeutic, pathogen‐specific, and cancer‐associated ...

Three phases in the evolution of the standard genetic code: how translation could get started [PDF]

open access: yes, 2007
A primordial genetic code is proposed, having only four codons assigned, GGC meaning glycine, GAC meaning aspartate/glutamate, GCC meaning alanine-like and GUC meaning valine-like.

Real-time, step-wise, electrical detection of protein molecules using dielectrophoretically aligned SWNT-film FET aptasensors [PDF]

open access: yes
Aptamer functionalized addressable SWNT-film arrays between cantilever electrodes were successfully developed for biosensor applications. Dielectrophoretically aligned SWNT suspended films made possible highly specific and rapid detection of target ...

A Modular DNAzyme for Precise Visualization and Intervention of Alternative Splicing Isoforms in Live Cells

open access: yesAdvanced Science, EarlyView.
A Stringent dUPlex‐activated Error Robust (SUPER) DNAzyme system enables real‐time imaging of alternative mRNA splicing (e.g., Bcl‐xL/Bcl‐xS) in living cells via target‐triggered split‐DNAzyme reassembly and dual‐color fluorescence. It also achieves mRNA‐selective knockdown through DNAzyme‐based gene regulation, serving as a versatile tool for splicing

Machine Learning‐Enhanced Analysis of Exosomal Surface Sialic Acid Using Surface‐Enhanced Raman Spectroscopy for Ovarian Cancer Diagnosis and Therapeutic Monitoring

open access: yesAdvanced Science, EarlyView.
Machine learning‐assisted surface‐enhanced Raman spectroscopy analysis of exosomal sialic acid for ovarian cancer diagnosis, as well as independent monitoring of exosomal sialic acid expression levels across different treatment periods, reveals a potential correlation with treatment response.
