Intraoperative Indocyanine Green Fluorescence Enables Primary Tumor Localization and Treatment De‐Escalation in SCCUP: A Case Report

Head &Neck, EarlyView.
ABSTRACT Background Unknown primary cancer in the head and neck presents a difficult surgical treatment dilemma. Patients with squamous cell carcinoma of unknown primary (SCCUP) typically present with an enlarging neck mass found on biopsy but with no indication of primary site on diagnostic exams such as flexible laryngoscopy, CT, MRI, and/or PET/CT ...

The Histone Methyltransferase SMYD2 Methylates PARP1 and Promotes Poly(ADP-ribosyl)ation Activity in Cancer Cells

Neoplasia: An International Journal for Oncology Research, 2014
Poly(ADP-ribose) polymerase-1 (PARP1) catalyzes the poly(ADP-ribosyl)ation of protein acceptors using NAD+ as the substrate is now considered as an important target for development of anticancer therapy. PARP1 is known to be post-translationally modified

PARP inhibitors affect growth, survival and radiation susceptibility of human alveolar and embryonal rhabdomyosarcoma cell lines [PDF]

, 2018
PARP inhibitors (PARPi) are used in a wide range of human solid tumours but a limited evidence is reported in rhabdomyosarcoma (RMS), the most frequent childhood soft-tissue sarcoma.

Downregulation of PARP1 transcription by CDK4/6 inhibitors sensitizes human lung cancer cells to anticancer drug-induced death by impairing OGG1-dependent base excision repair

Redox Biology, 2018
Hallmarks of cancer cells include uncontrolled growth and rapid proliferation; thus, cyclin-dependent kinases are a therapeutic target for cancer treatment.

USP1 deubiquitinates PARP1 to regulate its trapping and PARylation activity

Science Advances
PARP inhibitors (PARPi) represent a game-changing treatment for patients with ovarian cancer with tumors deficient for the homologous recombination (HR) pathway treated with platinum (Pt)–based therapy. PARPi exert their cytotoxic effect by both trapping

Berberine alleviates cell pyroptosis in diabetic retinopathy by regulating AKT1, JUN, and STAT3

Ibrain, EarlyView.
Berberine alleviates diabetic retinopathy by reducing pyroptosis through AKT1/JUN/STAT3 regulation, as validated in rat models via network pharmacology, molecular docking, and experimental assays. Abstract Berberine (BBR) exerts an effective protection for diabetic retinopathy (DR), but the underlying key molecular mechanism remains unknown; this study

DNA Checkpoint and Repair Factors Are Nuclear Sensors for Intracellular Organelle Stresses-Inflammations and Cancers Can Have High Genomic Risks. [PDF]

, 2018
Under inflammatory conditions, inflammatory cells release reactive oxygen species (ROS) and reactive nitrogen species (RNS) which cause DNA damage. If not appropriately repaired, DNA damage leads to gene mutations and genomic instability.

The Impact of Genetic Polymorphisms on Genotoxicity (DNA Damage) Among Children Exposed to Environmental Mutagens: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Children, as a particularly vulnerable group, are more susceptible to these mutagens due to their developing immune systems, higher physiological vulnerability, and increased exposure through behaviors like outdoor play and hand‐to‐mouth activities. This review aims to investigate the relationship between these environmental exposures, genetic

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

, 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 ...
