A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

An update on feline infectious peritonitis: diagnostics and therapeutics. [PDF]

open access: yes, 2014
This review is concerned with what has been learned about feline infectious peritonitis (FIP) diagnostics and therapeutics since the publication of an extensive overview of literature covering the period 1963-2009. Although progress has been made in both

Modifications in FLAP's second cytosolic loop influence 5‐LOX interaction, inhibitor binding, and leukotriene formation

open access: yesFEBS Letters, EarlyView.
The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

Compact zinc finger architecture utilizing toxin-derived cytidine deaminases for highly efficient base editing in human cells

open access: yesNature Communications
Nucleobase editors represent an emerging technology that enables precise single-base edits to the genomes of eukaryotic cells. Most nucleobase editors use deaminase domains that act upon single-stranded DNA and require RNA-guided proteins such as Cas9 to

Predicting therapeutic and aggravating drugs for hepatocellular carcinoma based on tissue-specific pathways [PDF]

open access: yesarXiv, 2017
Motivation: Hepatocellular carcinoma (HCC) is a significant health problem worldwide and annual number of cases are nearly more than 700,000. However,there are few safe and effective thera-peutic options for HCC patients.Here, we propose a new approach for predicting therapeutic and aggravating drugs for HCCbased ontissue-specificpathways, which ...

Protein-ligand interaction study to identify potential dietary compounds binding at the active site of therapeutic target proteins of SARS-CoV-2 [PDF]

open access: yesarXiv, 2020
Objective: Total 186 biologically important phenylpropanoids and polyketides compounds from different Indian medicinal plants and dietary sources were screened to filter potential compounds that bind at the active site of the therapeutic target proteins of SARS-CoV-2.

The carboxylate “gripper” of the substrate is critical for C‐4 stereo‐inversion by UDP‐glucuronic acid 4‐epimerase

open access: yesFEBS Letters, EarlyView.
UDP‐glucuronic acid 4‐epimerase (UGAepi) catalyzes NAD+‐dependent interconversion of UDP‐glucuronic acid (UDP‐GlcA) and UDP‐galacturonic acid (UDP‐GalA) via C4‐oxidation, 4‐keto‐intermediate rotation, and C4‐reduction. Here, Borg et al. examined the role of the substrate's carboxylate group in the enzymic mechanism by analyzing NADH‐dependent reduction

The Promising Viral Threat to Bacterial Resistance: The Uncertain Patentability of Phage Therapeutics and the Necessity of Alternative Incentives [PDF]

open access: yes, 2014
Bacteriophages, or “phages,” are a category of highly adept and adaptable viruses that can infect and kill bacteria. With concerns over the burgeoning antibiotic-resistance crisis looming in recent years, scientists and policymakers have expressed a ...

Photostimulated spin-flip and the photodynamic therapeutic effect of fullerene solutions [PDF]

open access: yesarXiv, 2010
A new mechanism of photodynamic therapeutic effect of fullerene solution is suggested. Spin flip of electrons in oxygen molecule in the vicinity of negative-positive ion pair of fullerene lays the foundation of high oxidative activity of complexes C60(minus) -O2 and C60(plus)-O2.
