Reactive Oxygen Species, Oxidative Damage, and Antioxidative Defense Mechanism in Plants under Stressful Conditions

open access: yes, 2012
Reactive oxygen species (ROS) are produced as a normal product of plant cellular metabolism. Various environmental stresses lead to excessive production of ROS causing progressive oxidative damage and ultimately cell death.

PLK1 facilitates chromosome biorientation by suppressing centromere disintegration driven by BLM-mediated unwinding and spindle pulling

open access: yesNature Communications, 2019
The kinase PLK1 has important roles during cell division, including mitotic entry and bipolar spindle formation. Here, the authors show that PLK1 also functions in centromere protection, with loss leading to DNA unwinding by Bloom’s syndrome helicase and

Bone Marrow CD133 Stem Cells Ameliorate Visual Dysfunction in Streptozotocin-induced Diabetic Mice with Early Diabetic Retinopathy

open access: yesCell Transplantation, 2018
Diabetic retinopathy (DR), one of the leading causes of vision loss worldwide, is characterized by neurovascular disorders. Emerging evidence has demonstrated retinal neurodegeneration in the early pathogenesis of DR, and no treatment has been developed ...

The Ku-binding motif is a conserved module for recruitment and stimulation of non-homologous end-joining proteins

open access: yesNature Communications, 2016
Werner syndrome is a progeroid disease characterised by genetic instability due to mutations to the WRN helicase/exonuclease. Here the authors define a novel Ku binding motif (KBM) and show that two such motifs facilitate the involvement of WRN in DNA ...

Automation of the cytokinesis-block micronucleus cytome assay by laser scanning cytometry and its potential application in radiation biodosimetry

open access: yesBioTechniques, 2014
Here we describe the adaptation of laser scanning cytometry (LSC) to measure micronuclei (MN) automatically in lymphocytes. MN frequencies were determined in irradiated human lymphocytes using the cytokinesis-block technique, and the results from LSC ...

DNA damage repair: historical perspectives, mechanistic pathways and clinical translation for targeted cancer therapy

open access: yesSignal Transduction and Targeted Therapy, 2021
Genomic instability is the hallmark of various cancers with the increasing accumulation of DNA damage. The application of radiotherapy and chemotherapy in cancer treatment is typically based on this property of cancers.

Olfactory Ensheathing Cells Inhibit Gliosis in Retinal Degeneration by Downregulation of the Müller Cell Notch Signaling Pathway

open access: yesCell Transplantation, 2017
Retinal regeneration and self-repair, whether in response to injury or degenerative disease, are severely impeded by glial scar formation by Müller cells (specialized retinal macroglia). We have previously demonstrated that the activation of Müller cells

Liver stiffness and arterial stiffness/abnormal central hemodynamics in the early stage of heart failure

open access: yesInternational Journal of Cardiology: Heart & Vasculature, 2018
Background: It remains to be clarified whether liver stiffness is a direct risk factor for heart failure (HF) or whether its association with HF is mediated by vascular damage.

Measurements of elastic properties and their dependencies within a damage mechanics workflow

open access: yesRock Mechanics Bulletin, 2023
Experimental rock mechanics testing provides a controlled and effective method for measuring physical properties, their dependencies, and their evolution due to the addition of localized microcracks.
