DNA Repair Gene Polymorphisms May Be Associated with Prognosis of Upper Urinary Tract Transitional Cell Carcinoma

Neoplasia: An International Journal for Oncology Research, 2008
Upper urinary tract transitional cell carcinoma (UUT-TCC) is quite an uncommon disease, and its prognosis differs among individuals irrespective of tumor stage. DNA repair gene polymorphisms are reported to result in the modulation of the repair capacity

Development of 4T1 breast cancer mouse model system for preclinical carbonic anhydrase IX studies

FEBS Open Bio, EarlyView.
Carbonic anhydrase IX (CAIX) is a well‐recognised therapeutic target and prognostic biomarker in cancer. We developed and characterised a robust murine breast cancer model system that is suitable for CAIX studies in vitro and in vivo—it comprises both CAIX‐positive and CAIX‐negative controls and provides a solid platform for the comprehensive ...

Interplay of replication timing, DNA repair, and translesion synthesis in UV mutagenesis in yeast

Nucleus
Replication timing during S-phase impacts mutation rates in yeast and human cancers; however, the exact mechanism involved remains unclear. Here, we analyze the impact of replication timing on UV mutagenesis in Saccharomyces cerevisiae.

C. elegans survival assays to discern global and transcription-coupled nucleotide excision repair

STAR Protocols, 2021
Summary: Global genome nucleotide excision repair (GG-NER) and transcription-coupled nucleotide excision repair (TC-NER) protect cells against a variety of helix-distorting DNA lesions. In C. elegans, GG-NER primarily acts in proliferative germ cells and

Chromatin structure and DNA damage repair

Epigenetics & Chromatin, 2008
The integrity of the genome is continuously challenged by both endogenous and exogenous DNA damaging agents. These damaging agents can induce a wide variety of lesions in the DNA, such as double strand breaks, single strand breaks, oxidative lesions and ...

Ubiquitin-specific Protease 7 Regulates Nucleotide Excision Repair through Deubiquitinating XPC Protein and Preventing XPC Protein from Undergoing Ultraviolet Light-induced and VCP/p97 Protein-regulated Proteolysis*

Journal of Biological Chemistry, 2014
Background: XPC protein is ubiquitinated, but the ubiquitination does not lead to significant proteolysis of XPC. Results: Ubiquitin-specific protease 7 is a deubiquitinating enzyme (DUB) for XPC.

Liver‐specific lncRNAs associated with liver cancers

FEBS Open Bio, EarlyView.
Long non‐coding RNAs (lncRNAs) are regulatory molecules with various functions. They are more tissue‐specific than proteins and can be used as potential biomarkers, particularly in cancer diagnostics and prognosis. In this review, we have systematically compiled all lncRNAs with exclusive expression in the human liver, verified their liver specificity ...

CBP and p300 acetylate PCNA to link its degradation with nucleotide excision repair synthesis

Nucleic Acids Research, 2014
The proliferating cell nuclear antigen (PCNA) protein serves as a molecular platform recruiting and coordinating the activity of factors involved in multiple deoxyribonucleic acid (DNA) transactions. To avoid dangerous genome instability, it is necessary

Characterization of WAC interactions with R2TP and TTT chaperone complexes linking glucose and glutamine availability to mTORC1 activity

FEBS Open Bio, EarlyView.
TTT and R2TP chaperone complexes are required for the assembly and activation of mTORC1. WAC directly interacts with components of TTT, R2TP, and mTORC1, and these interactions are affected by the availability of glucose and glutamine, correlating with changes in mTORC1 activity.

Molecular Mechanism of Global Genome Nucleotide Excision Repair

Acta Naturae, 2014
Nucleotide excision repair (NER) is a multistep process that recognizes and eliminates a wide spectrum of damage causing significant distortions in the DNA structure, such as UV-induced damage and bulky chemical adducts. The consequences of defective NER
