Dasatinib and quercetin prevent alveolar bone loss in aged mice

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Recent findings have associated alveolar bone loss (ABL) with the presence of senescent cells. Aging and the accumulation of senescent cells are associated with a pro‐inflammatory environment which may exacerbate tissue damage.

Architecture of a PKS-NRPS hybrid megaenzyme involved in the biosynthesis of the genotoxin colibactin

open access: yes, 2023
International audienceThe genotoxin colibactin produced by Escherichia coli is involved in the development of colorectal cancers. This secondary metabolite is synthesized by a multi-protein machinery, mainly composed of non-ribosomal peptide synthetase ...

Catechins and Their Effect on the Gut Microbiome in Health and Cancer

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Catechins are a group of flavonoids found primarily in green tea, fruits, and berries; they play a significant role in the modulation of the gut microbiota, thereby having an impact on gut health and cancer prevention. Owing to their low bioavailability, catechins are transformed by the gut microbiota into various bioactive metabolites such as

Sequence Variability of P2-Like Prophage Genomes Carrying the Cytolethal Distending Toxin V Operon in Escherichia coli O157 [PDF]

open access: yes, 2013
Cytolethal distending toxins (CDT) are potent cytotoxins of several Gram-negative pathogenic bacteria, including Escherichia coli, in which five types (CDT-I to CDT-V) have been identified so far.

Protocol for HeLa Cells Infection with Escherichia coli Strains Producing Colibactin and Quantification of the Induced DNA-damage

open access: yesBio-Protocol, 2017
Strains of Escherichia coli bearing the pks genomic island synthesize the genotoxin colibactin. Exposure of eukaryotic cells to E. coli producing colibactin induces DNA damages, ultimately leading to cell cycle arrest, senescence and death.

Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

open access: yesThe FEBS Journal, EarlyView.
DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

Adherens junction-dependent PI3K/Akt activation induces resistance to genotoxin-induced cell death in differentiated intestinal epithelial cells.

open access: yes, 2009
The crypt-villi axis of intestinal mucosa maintains homeostasis by renewal of epithelia, and also exhibits different properties from undifferentiated to terminally differentiated cells.

Benzo[a]pyrene, aflatoxine B₁ and acetaldehyde mutational patterns in TP53 gene using a functional assay: relevance to human cancer aetiology.

open access: yesPLoS ONE, 2012
Mutations in the TP53 gene are the most common alterations in human tumours. TP53 mutational patterns have sometimes been linked to carcinogen exposure.

Analysis of the role of the Fun30 CUE motif in genotoxin resistance.

open access: yes, 2015
(A) Schematic of Fun30 protein. The CUE motif and ATPase domain are indicated. (B) The CUE motif of Fun30 is not required for genotoxin resistance. Growth phenotypes of strains 89 through 93 on indicated media are shown. Note pRS414-FUN30-CUE** encodes a

Rising Incidence and Mortality of Colorectal Cancer Among Younger Adults: A Population‐Based Study in Taiwan, 1994–2018

open access: yesInternational Journal of Cancer, Volume 159, Issue 8, Page 1928-1936, 15 October 2026.
Colorectal cancer incidence and mortality have increased in the Asia‐Pacific region over the past three decades. This population‐based study in Taiwan suggests a shift of the colorectal cancer burden towards the younger generations. An age–period–cohort model revealed higher annual increases in incidence (3.58%) and mortality (1.0%) rates among ...
