Assessment of Poly(ADP-ribose) Polymerase1 (PARP1) expression and activity in cells purified from blood and milk of dairy cattle [PDF]

, 2018
Poly(ADP-ribosyl)ation (PAR) is a post-translational protein modification catalysed by enzyme member of the poly(ADP-ribose) polymerases (PARPs) family. The activation of several PARPs is triggered by DNA strand breakage and the main PARP enzyme involved

Multi‐Omics Profiling Uncovers Predictive Factors for Tumor‐Infiltrating Lymphocyte Therapy in Ovarian Cancer

Journal of Clinical Laboratory Analysis, EarlyView.
We profiled tumors from 10 ovarian cancer patients with whole‐exome sequencing (WES), bulk RNA‐seq, and single‐cell RNA‐seq to uncover predictors of successful tumor‐infiltrating lymphocyte (TIL) isolation and expansion. TIL+ tumors exhibited enriched CD8+ Teff/Tem populations with distinctive metabolic activity, dendritic‐cell–skewed myeloid states ...

Inhibition of poly(ADP-ribose) polymerase interferes with Trypanosoma cruzi infection and proliferation of the parasite.

PLoS ONE, 2012
Poly(ADP-ribosylation) is a post-translational covalent modification of proteins catalyzed by a family of enzymes termed poly(ADP-ribose) polymerases (PARPs).

Prediction Of Cancer Possibility By Pattern Recognition And Statistical Study Of Expression Of Gene Level Of Cancer Cells [PDF]

, 2011
The activity of the p53 tumor-suppressor protein has a key role in controlling both cancer and aging: under activity encourages the growth of cancer, and over activity can accelerate the aging process.

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

NAD+ analog reveals PARP-1 substrate-blocking mechanism and allosteric communication from catalytic center to DNA-binding domains

Nature Communications, 2018
Poly(ADP-ribose) polymerases (PARPs) catalyse ADP-ribose posttranslational modifications using NAD+ as a substrate. Here, the authors present the crystal structure of PARP-1 bound to the non-hydrolyzable NAD+ analog BAD and provide insights into the ...

Posttranscriptional regulation of PARG mRNA by HuR facilitates DNA repair and resistance to PARP inhibitors [PDF]

, 2017
The majority of pancreatic ductal adenocarcinomas (PDAC) rely on the mRNA stability factor HuR (ELAV-L1) to drive cancer growth and progression. Here, we show that CRISPR-Cas9–mediated silencing of the HuR locus increases the relative sensitivity of PDAC

His+ reversions Caused in Salmonella typhimurium by different types of ionizing radiation [PDF]

, 1988
The yield of his+ reversions in the Ames Salmonella tester strain TA2638 has been determined for 60Co γ rays, 140 kV X rays, 5.4 keV characteristic X rays, 2.2 MeV protons, 3.1 MeV α particles, and 18 MeV/U Fe ions.

Early Dapagliflozin and Melatonin Treatment Ameliorated LV Fibrosis via Suppressing TGF‐β1/Smads and Activating Nrf2‐ARE Signaling in MI Rodent

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study tested whether combined dapagliflozin (DAPA) and melatonin (Mel) therapy was superior to merely one for ameliorating the left ventricular (LV) fibrosis/remodeling and improving LV ejection fraction (LVEF) in rats after acute myocardial infarction (AMI). In vitro study demonstrated that DAPA treatment significantly suppressed the TGF‐
