A polymorphism in the base excision repair gene PARP2 is associated with differential prognosis by chemotherapy among postmenopausal breast cancer patients. [PDF]

open access: yes, 2015
BACKGROUND: Personalized therapy considering clinical and genetic patient characteristics will further improve breast cancer survival. Two widely used treatments, chemotherapy and radiotherapy, can induce oxidative DNA damage and, if not repaired, cell ...

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

Selective small molecule targeting of KDM4 as a therapeutic strategy to reduce proliferation of acute myeloid leukaemia

open access: yesBritish Journal of Haematology, EarlyView.
Summary Acute myeloid leukaemia (AML) is an aggressive disease with poor survival and high relapse rates. Coupled with the complex mutational burden observed, there is an unmet clinical need for more targeted therapies. Epigenetic therapies have shown promise both as monotherapy and in combination strategies and specifically histone lysine demethylase,

PARP1 bound to XRCC2 promotes tumor progression in colorectal cancer

open access: yesDiscover Oncology
Background By complexing poly (ADP-ribose) (PAR) in reaction to broke strand, PAR polymerase1 (PARP1) acts as the key enzyme participated in DNA repair.

Synergistic RU486 and olaparib therapy enhances apoptosis in endometriosis by simultaneously targeting hormonal signalling and DNA repair

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Endometriosis is a chronic, hormone‐dependent disorder characterized by ectopic implantation of endometrial tissue, often accompanied by pain and infertility. Although the progesterone receptor modulator RU486 is effective for pain relief, its impact on lesion regression is limited, possibly due to apoptosis resistance and ...

Enhancing antitumour response to proteasome inhibitors with inhibitors of insulin‐degrading enzyme, a new molecular vulnerability in multiple myeloma

open access: yesBritish Journal of Pharmacology, EarlyView.
Inhibitors of insulin‐degrading enzyme boost PI cytotoxicity through an increased sensitivity of proteasome to PI inhibitors, induction of ISR, DNA damage and Myc down‐regulation. They overcome PI resistance in vitro and induce tumour regression in vivo.

Early‐Onset Digestive System Cancers: Risk Factors and Clinicopathological and Molecular Features Across Organ Sites

open access: yesCancer Science, EarlyView.
Shared risk factors, clinical features, and tumor characteristics across multiple early‐onset cancer types are shown in this Graphical Abstract. Integrative approaches combining molecular pathology, oncology, and population sciences offer opportunities to clarify underlying mechanisms and help us develop preventive strategies for early‐onset cancers ...

Automodification of N‐terminal serine residues facilitates PARP2 release from DNA

open access: yesThe FEBS Journal, EarlyView.
PARP2 is involved in detecting DNA damage and its N‐terminal role is largely unknown. Based on biochemical and biophysical data, our findings suggest that in the presence of HPF1, N‐terminal serine 8 and 73 are enriched in auto‐ADP‐ribosylation. Our results provide insight into the mechanistic role of PARP2 N‐terminus in the PARylation‐dependent ...

Steroidogenic compensation and lipid deficiency with enhanced NAD+ salvage in small‐for‐gestational‐age placenta

open access: yesThe FEBS Journal, EarlyView.
Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.
