Epigenetic remodeling during arsenical-induced malignant transformation

We evaluated the potential epigenetic component of arsenical action by assessing the histone acetylation state of 13 000 human gene promoters in a cell line model of arsenical-mediated malignant transformation. We show changes in hi...

Aspergillus niger decreases bioavailability of arsenic(V) via biotransformation of manganese oxide into biogenic oxalate minerals

of the transformation on mobility and bioavailability of arsenic. Our results showed that the A. niger strain CBS 140837 greatly affected the stability of hausmannite and induced% of manganese was bioextracted, the arsenic...

Examination of the effects of arsenic on glucose homeostasis in cell culture and animal studies: Development of a mouse model for arsenic-induced diabetes

The paper reviews the results of laboratory studies that examined the effects of iAs on glucose metabolism and describes new experiments in which the diabetogenic effects of iAs exposure were reproduced in a mouse model....

Arsenicals produce stable progressive changes in DNA methylation patterns that are linked to malignant transformation of immortalized urothelial cells

Aberrant DNA methylation participates in carcinogenesis and is a molecular hallmark of a tumor cell. We used a model of arsenical-induced malignant transformation of immortalized human urothelial cells and DNA methylation microarray...

Alternative pathways of programmed cell death are activated in cells with defective caspase-dependent apoptosis

Loss of programmed cell death pathways is one of the features of malignancy that complicate the response of cancer cells to a therapy. We analysed programmed cell death pathways of v-myb-transformed BM2 monoblasts induced by arsenic...

Methylated trivalent arsenicals are potent inhibitors of glucose stimulated insulin secretion by murine pancreatic islets

The insulin producing pancreatic ?-cells are among the targets for As exposure and the inhibition of glucose stimulated insulin secretion by low concentrations of the methylated metabolites of iAs may be the key mechanism of iAs-induced diab...

The effect of arsenic contamination of environment on plant metabolism

Arsenic (As) is not essential for plant metabolism. In soils, it forms highly phytotoxic. In soil As typically occurs as arsenate (AsV) and arsenite (AsIII, As induces a specific stress metabolism, determines transport and ...
