IncRNA‐ZFAS1, an Emerging Gate‐Keeper in DNA Damage‐Dependent Transcriptional Regulation

Advanced Science, EarlyView.
LncZFAS1 plays a crucial role during DNA damage response in mammalian cells. Loss of lncZFAS1 results in deficient DNA lesion removal and reduced cell viability. Mechanistically, lncZFAS1 modulates RNAPII phosphorylation and transcription and thereby promotes both GG‐NER and TC‐NER upon UV damage.

Mouse spermatocytes express CYP2E1 and respond to acrylamide exposure.

PLoS ONE, 2014
Metabolism of xenobiotics by cytochrome P450s (encoded by the CYP genes) often leads to bio-activation, producing reactive metabolites that interfere with cellular processes and cause DNA damage.

Tailoring a Functional Synthetic Microbial Community Alleviates Fusobacterium nucleatum‐infected Colorectal Cancer via Ecological Control

Advanced Science, EarlyView.
The bottom‐up strategy based on multiomics data is used for the SynCom design, and it successfully inhibited F. nucleatum growth and achieved stable colonization in vivo. In addition, it promoted tryptophan metabolism and secondary bile acid conversion, reduced lipid accumulation, relieved microbiome disorder, decreased inflammatory reaction, and ...

ERCC1 and ERCC2 haplotype modulates induced BPDE-DNA adducts in primary cultured lymphocytes. [PDF]

PLoS ONE, 2013
BACKGROUND: Benzo[a]pyrene(B[a]P), and its ultimate metabolite Benzo[a]pyrene 7,8-diol 9,10-epoxide (BPDE), are classic DNA damaging carcinogens. DNA damage caused by BPDE is normally repaired by Nucleotide Excision Repair (NER), of which ERCC1 and ERCC2/

Designing organometallic compounds for catalysis and therapy [PDF]

, 2012
Bioorganometallic chemistry is a rapidly developing area of research. In recent years organometallic compounds have provided a rich platform for the design of effective catalysts, e.g. for olefin metathesis and transfer hydrogenation.

POLE Deficiency Exacerbates Diesel Engine Exhaust‐Induced Genomic Instability and Malignant Transformation of Bronchial Epithelial Cells

Advanced Science, EarlyView.
This study establishes a diesel engine exhaust (DEE)‐induced malignant transformation model in bronchial epithelial cells. Whole genome sequencing（WGS） and RNA‐seq reveal DEE‐induced mutational signatures and gene expression profiles. Mechanistically, DEEaffect polymerase epsilon (POLE) and mismatch repair, driving genomic instability and promoting ...
