Tyrosyl-DNA phosphodiesterase and the repair of 3'-phosphoglycolate-terminated DNA double-strand breaks

172 views | Mar 26 2019

Zhou T et al. indicated This chromosomal hypersensitivity, as well as a small but reproducible enhancement of calicheamicin cytotoxicity following siRNA-mediated TDP1 knockdown, suggests a role for TDP1 in repair of 3'-PG double-strand breaks in vivo. [Read the Full Post]

DNA-PK inhibition by NU7441 sensitizes breast cancer cells to ionizing radiation and doxorubicin

204 views | Mar 26 2019

Ciszewski WM et al. indicated that DNA-PK might be an effective target for chemo- and radio-potentiation in breast cancer and suggest that further development of DNA-PK inhibitors for clinical use is warranted. [Read the Full Post]

Artesunate enhances the therapeutic response of glioma cells to temozolomide by inhibition of homologous recombination and senescence

378 views | Oct 07 2018

Berte N et al. showed the amelioration of TMZ-induced cell death upon ART co-treatment provides a rational basis for a combination regime of TMZ and ART in glioblastoma therapy. [Read the Full Post]

ATM induces MacroD2 nuclear export upon DNA damage

682 views | Oct 03 2018

Golia B et al. identified a novel feedback regulation between two crucial DNA damage-induced signaling pathways: ADP-ribosylation and ATM activation. [Read the Full Post]

Phosphoinositide 3-Kinase Is Involved in Mediating the Anti-inflammation Effects of Vasopressin

699 views | Jun 07 2018

Jan WC et al. confirmed that PI3K, especially the isoforms of PI3Kβ, PI3Kδ, and PI3Kγ, is involved in mediating the anti-inflammatory effects of vasopressin. [Read the Full Post]

Targeting DNA repair with aphidicolin sensitizes primary chronic lymphocytic leukemia cells to purine analogs

888 views | Jan 19 2018

Starczewska E et al. indicated that aphidicolin potentiates the cytotoxicity of purine analogs by inhibiting a DNA repair pathway that involves DNA polymerases, most likely NER, and provide a rationale for manipulating it to therapeutic advantage. [Read the Full Post]

DNA damage response curtails detrimental replication stress and chromosomal instability induced by the dietary carcinogen PhIP

702 views | Jan 18 2018

Mimmler M et al. supported the notion that ATR plays a key role in the defense against cancer formation induced by PhIP and related HCAs. [Read the Full Post]

Development of novel PET probes targeting phosphatidylinositol 3-kinase (PI3K) in tumors

734 views | Jan 18 2018

Makino A et al. represented the first trial of a PET tracer for detecting PI3K. Although further improvement of the probe is required prior to clinical application, these results should encourage future work. [Read the Full Post]

PKCiota promotes ovarian tumor progression through deregulation of cyclin E

1246 views | Dec 19 2017

Nanos-Webb A et al. identified a PI3K/PKCiota/cyclin E signaling pathway as a therapeutic target during ovarian tumorigenesis. [Read the Full Post]
