Liver Damage in Patients with HCV/HIV Coinfection Is Linked to HIV-Related Oxidative Stress [PDF]

open access: yes, 2016
HIV infection aggravates the progression of liver damage in HCV-coinfected patients, with the underlying pathogenesis being multifactorial. Although high level of oxidative stress has been observed frequently in patients infected with HIV or HCV, the ...

Oxidative RNA Damage and Neurodegeneration

open access: yesCurrent Medicinal Chemistry, 2007
Although cellular RNA should be subject to the same oxidative insults as DNA and other cellular macromolecules, oxidative damage to RNA has not been a major focus in investigating the magnitude and the biological consequences of the free radical damage.

Potential of cyclodipeptides in combating oxidative stress in chronic diseases

open access: yesPharmacological Research
Oxidative stress results from an imbalance between free radicals—such as reactive oxygen species (ROS) and reactive nitrogen species (RNS)—and the body’s antioxidant defenses.

The Nervous System Cytoskeleton under Oxidative Stress

open access: yesDiseases, 2013
Oxidative stress is a key mechanism causing protein aggregation, cell death and neurodegeneration in the nervous system. The neuronal cytoskeleton, that is, microtubules, actin filaments and neurofilaments, plays a key role in defending the nervous ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Melatonin inhibits apoptosis and oxidative tissue damage in cisplatin-induced pulmonary toxicity in rats

open access: yes, 2020
Introduction Cisplatin is one of the most frequently used chemotherapeutics, which is known to cause both tumor and normal lung tissue damage through the generation of free radicals and cells apoptosis/necrosis. Melatonin is a neurohormone that regulates

Age Associated Oxidative Damage in Lymphocytes [PDF]

open access: yesOxidative Medicine and Cellular Longevity, 2010
Lymphocytes are an important immunological cell and have been played a significant role in acquired immune system; hence, may play in pivotal role in immunosenescence. Oxidative stress has been reported to increase in elderly subjects, possibly arising from an uncontrolled production of free radicals with aging and decreased antioxidant defenses.

Mitochondrial DNA is a sensitive surrogate and oxidative stress target in oral cancer cells.

open access: yesPLoS ONE
Cellular oxidative stress mediated by intrinsic and/or extrinsic reactive oxygen species (ROS) is associated with disease pathogenesis. Oxidative DNA damage can naturally be substituted by mitochondrial DNA (mtDNA), leading to base lesion/strand break ...

Pentose phosphate pathway regulates oxidative damage and apoptosis of chondrocytes induced by fluoride

open access: yesEcotoxicology and Environmental Safety
Fluorosis is a systemic disorder with primary manifestations including skeletal and dental fluorosis, where skeletal fluorosis is associated with cartilage lesions.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
