SARS-CoV-2 and miRNA-like inhibition power [PDF]

open access: yesarXiv, 2020
(1) Background: RNA viruses and especially coronaviruses could act inside host cells not only by building their own proteins, but also by perturbing the cell metabolism. We show the possibility of miRNA-like inhibitions by the SARS-CoV-2 concerning for example the hemoglobin and type I interferons syntheses, hence highly perturbing oxygen distribution ...

Unleashing the Power of Multiomics: Unraveling the Molecular Landscape of Peripheral Neuropathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Peripheral neuropathies (PNs) affect over 20 million individuals in the United States, manifesting as a wide range of sensory, motor, and autonomic nerve symptoms. While various conditions such as diabetes, metabolic disorders, trauma, autoimmune disease, and chemotherapy‐induced neurotoxicity have been linked to PN, approximately one‐third of

RNA polymerase motors on DNA track: effects of traffic congestion on RNA synthesis [PDF]

open access: yesarXiv, 2007
RNA polymerase (RNAP) is an enzyme that synthesizes a messenger RNA (mRNA) strand which is complementary to a single-stranded DNA template. From the perspective of physicists, an RNAP is a molecular motor that utilizes chemical energy input to move along the track formed by a ssDNA.

Activation of SIRT1 Reduces Renal Tubular Epithelial Cells Fibrosis in Hypoxia Through SIRT1‐FoxO1‐FoxO3‐Autophagy Pathway

open access: yesAdvanced Biology, EarlyView.
Hypoxia promotes the epithelial‐mesenchymal transition (EMT) of renal tubular epithelial cells via the SIRT1‐FoxO1‐FoxO3‐autophagy pathway, thereby resulting in the fibrosis of renal tubular epithelial cells. Activation of SIRT1 or induction of autophagy inhibits this process, alleviating hypoxia‐induced fibrosis.

RNA polymerase motor on DNA track: effects of interactions, external force and torque [PDF]

open access: yesarXiv, 2008
RNA polymerase (RNAP) is a mobile molecular workshop that polymerizes a RNA molecule by adding monomeric subunits one by one, while moving step by step on the DNA template itself. Here we develop a theoretical model by incorporating the steric interactions of the RNAPs and their mechanochemical cycles which explicitly captures the cyclical shape ...

Regulating Protein Immobilization During Cell‐Free Protein Synthesis in Hyaluronan Microgels

open access: yesAdvanced Biology, EarlyView.
Bifunctional microgels carrying a linear DNA template and Ni2+‐activated NTA moieties are used as platform for cell‐free protein synthesis and in situ protein immobilization. By varying the concentration of NTA moieties in the microgels, the amount of GFP‐His immobilized inside the microgel and released to the microgel environment can be regulated ...

Amplification‐Free, Sequencing‐Free, Detection of Viral RNAs with Variant Specification by Discrete Nanocounting

open access: yesAdvanced Functional Materials, EarlyView.
Integrating selective RNA shortcut, targeted gene isolation, and micro‐arrayed nanoimaging, the NanoPick‐array platform excels in detecting severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) at just 60 copies µL−1 and accurately differentiating variants at the single‐nucleotide level. It ensures 100% accuracy for samples with cycle threshold (
