Defective DNA repair mechanisms in prostate cancer: impact of olaparib [PDF]

, 2017
The field of prostate oncology has continued to change dramatically. It has truly become a field that is intensely linked to molecular genetic alterations, especially DNA-repair defects.

Poly(ADP-ribose) polymerase 1 activation is required for cisplatin nephrotoxicity [PDF]

Kidney International, 2012
Apoptosis, necrosis, and inflammation are hallmarks of cisplatin nephrotoxicity; however, the role and mechanisms of necrosis and inflammation remains undefined. As poly(ADP-ribose) polymerase 1 (PARP1) inhibition or its gene deletion is renoprotective in several renal disease models, we tested whether its activation may be involved in cisplatin ...

One size does not fit all: An in vitro evaluation of the effects of bezafibrate and medroxyprogesterone acetate on human SH‐SY5Y and U‐87 MG cancer cells

FEBS Open Bio, EarlyView.
Drugs previously repurposed to target blood cancers reduced neuroblastoma and glioblastoma cell growth and viability. However, their levels of anticancer activity were different and their clinical application may be problematic due to side effects at effective doses.

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Selenium‐Based Nanoplatforms: An Emerging Theranostic Paradigm for Gynecological Cancers

Advanced Science, EarlyView.
This reivew summarizes Selenium as a multifunctional anticancer regulator in gynecological cancers. It reduces tumor risk, enhances therapeutic efficacy, and reduces treatment toxicity. Selenium also overcomes chemoraditherapy resistance, improving overall treatment outcomes. ABSTRACT Gynecological cancers present significant therapeutic challenges due

PARP1 and PARG Are the Draft Horses for Polycomb-Trithorax Chromatin Regulator Machinery

Biomolecules
During tissue differentiation, gene expression patterns are committed to the epigenetic cellular memory machinery, including Polycomb and Trithorax groups (PcG and TrxG), which label chromatin with repressive or active histone marks.

Identification of probe-quality degraders for Poly(ADP-ribose) polymerase-1 (PARP-1)

Journal of Enzyme Inhibition and Medicinal Chemistry, 2020
Poly(ADP-ribose) polymerase-1 (PARP-1), a critical DNA repair enzyme in the base excision repair pathway, has been pursued as an attractive cancer therapeutic target.

Ischemic Preconditioning by Caspase Cleavage of Poly(ADP-Ribose) Polymerase-1 [PDF]

The Journal of Neuroscience, 2003
A transient, sublethal ischemic interval confers resistance to a subsequent, otherwise lethal ischemic insult, in a process termed ischemic preconditioning. Poly(ADP-ribose) polymerase-1 (PARP-1) normally functions in DNA repair, but extensive PARP-1 activation is a major cause of ischemic cell death.

Hepatotoxicity of Nonesterified Fatty Acids to Dairy Cows: Pathophysiological Mechanisms and Prospective Solutions

Animal Research and One Health, EarlyView.
Unregulated inflammation increases non‐esterified fatty acids (NEFAs), and triggers multi‐pathway hepatocyte damage including oxidative stress, mitochondrial dysfunction, and metabolic disorders in dairy cows. ABSTRACT Circulating concentrations of nonesterified fatty acids (NEFAs) are elevated due to lipid mobilization from adipose tissue in ...
