Nitrosylcobalamin Selectively Targets Tumors via Cobalamin Uptake and Lysosomal Processing

open access: yesFrontiers in Bioscience-Elite
Background: Nitrosylcobalamin (NO-Cbl) is a vitamin B12 analog designed to exploit the “Trojan horse” vulnerability created by the heightened need of cancer cells for cobalamin and one-carbon metabolism.

Short-Term Low Temperature Induces Nitro-Oxidative Stress that Deregulates the NADP-Malic Enzyme Function by Tyrosine Nitration in Arabidopsis thaliana

open access: yesAntioxidants, 2019
Low temperature (LT) negatively affects plant growth and development via the alteration of the metabolism of reactive oxygen and nitrogen species (ROS and RNS).

Association of Vitamin D Receptor Gene Polymorphisms and Hypovitaminosis D with Reduced Bone Mineral Density in Survivors of Childhood Leukemia: A Study in Algerian Patients

open access: yesCurrent Issues in Molecular Biology
Survivors of childhood leukemia are at increased risk of long-term skeletal complications, including reduced bone mineral density (BMD). Vitamin D deficiency and genetic variations in the vitamin D receptor (VDR) gene are important factors influencing ...

Nitric oxide and nitric oxide synthase in Huntington's disease [PDF]

open access: yesJournal of Neuroscience Research, 2001
AbstractNitric oxide (NO) is a biologically active inorganic molecule produced when the semiessential amino acid l‐arginine is converted to l‐citrulline and NO via the enzyme nitric oxide synthase (NOS). NO is known to be involved in the regulation of many physiological processes, such as control of blood flow, platelet adhesion, endocrine function ...

Nitric Oxide in Hypertension [PDF]

open access: yesThe Journal of Clinical Hypertension, 2006
Hypertension is a major risk factor for cardiovascular disease, and reduction of elevated blood pressure significantly reduces the risk of cardiovascular events. Endothelial dysfunction, which is characterized by impairment of nitric oxide (NO) bioavailability, is an important risk factor for both hypertension and cardiovascular disease and may ...

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 ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Reactive Oxygen Species (ROS) Metabolism and Nitric Oxide (NO) Content in Roots and Shoots of Rice (Oryza sativa L.) Plants under Arsenic-Induced Stress

open access: yesAgronomy, 2020
Arsenic (As) is a highly toxic metalloid for all forms of life including plants. Rice is the main food source for different countries worldwide, although it can take up high amounts of As in comparison with other crops, showing toxic profiles such as ...

PARP inhibitors induce a senescence phenotype in non‐small cell lung carcinoma cell lines

open access: yesFEBS Open Bio, EarlyView.
Talazoparib is the most potent inducer of senescence among different PARP1 inhibitors in human NSCLC cells. In the absence of PARP, no senescence phenotype was observed, demonstrating that PARP1 is necessary for the induction of senescence by this inhibitor.
