Induction of histone H1.2 cytosolic release in chronic lymphocytic leukemia cells after genotoxic and non-genotoxic treatment

open access: yesHaematologica, 2008
Background The aim of this study was to analyze whether in chronic lymphocytic leukemia the cytosolic release of histone H1.2, a new apoptogenic mechanism induced by DNA damage, was associated with the presence of genetic abnormalities and with the ...

TP53 R249S mutation in hepatic organoids captures the predisposing cancer risk

open access: yesHepatology, EarlyView., 2022
The systematic approach in elucidating the gain‐of‐function (GOF) roles of TP53 mutations in early liver carcinogenesis. Unique downstream targets of TP53 L3 mutations were identified from chormatin immunoprecipitation sequencing in HCC cell lines, followed by a series of validation assays to substantiate the exclusive transcriptional regulations ...

Scientific Opinion on the safety and efficacy of Hostazym C (endo-1,4-beta-glucanase) as feed additive for chickens for fattening, all other birds for fattening and piglets (weaned) [PDF]

open access: yesEFSA Journal, 2013
Hostazym C is an enzyme preparation of endo-1,4-beta-glucanase produced by a non-genetically modified strain of Trichoderma citrinoviride. The results of an in vitro chromosomal aberration test and of an in vivo comet assay indicate the presence of ...

Cancer risk estimation of genotoxic chemicals based on target dose and a multiplicative model

open access: yes, 1999
A mechanistic model and associated procedures are proposed for cancer risk assessment of genotoxic chemicals. As previously shown for ionizing radiation, a linear multiplicative model was found to be compatible with published experimental data for ...

MITF maintains genome stability in nonmelanocyte lineages

open access: yesMolecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created
