DNA Damage Response Signals Transduce Stress From Rheumatoid Arthritis Risk Factors Into T Cell Dysfunction

Frontiers in Immunology, 2018
Rheumatoid arthritis (RA) is an autoimmune-mediated disease that is associated with significant cartilage damage and immunosenescence. Despite decades of research, the major signal pathways that initiate RA are still unclear. The DNA damage response (DDR)

Distinct characteristics of the DNA damage response in mammalian oocytes

Experimental and Molecular Medicine
DNA damage is a critical threat that poses significant challenges to all cells. To address this issue, cells have evolved a sophisticated molecular and cellular process known as the DNA damage response (DDR).

The DNA damage response during mitosis

, 2013
Cells are equipped with a cell-intrinsic signaling network called the DNA damage response (DDR). This signaling network recognizes DNA lesions and initiates various downstream pathways to coordinate a cell cycle arrest with the repair of the damaged DNA.

From anthelmintic to neuro‐oncology: A systematic review of mebendazole repurposing for brain tumour therapy

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Mebendazole (MBZ), a benzimidazole anthelmintic with established clinical use, has emerged as a repurposing candidate for primary brain tumours due to its multimodal anticancer actions and central nervous system penetrance. This systematic review synthesizes preclinical and clinical evidence evaluating MBZ's efficacy, mechanisms of action ...

Triggered Calcium Lightning Programs Cochlear Development

Exploration, EarlyView.
Summary: Before the onset of hearing, the developing inner ear generates spontaneous calcium signals that are thought to guide maturation. In this study, we discovered a rapid and widespread calcium flash—dubbed “Ca2+ lightning”—originating from supporting cells beneath the sensory hair cells, which triggers coordinated calcium waves across the entire ...

Increased DNA damage in full-grown oocytes is correlated with diminished autophagy activation

Nature Communications
Unlike mild DNA damage exposure, DNA damage repair (DDR) is reported to be ineffective in full-grown mammalian oocytes exposed to moderate or severe DNA damage. The underlying mechanisms of this weakened DDR are unknown.

Merkel Cell Polyomavirus and DNA Damage Response (DDR): Transcriptional Analysis of DDR Pathways in the Context of Merkel Cell Carcinoma

Cancers
Background/Objectives: Merkel cell polyomavirus (MCPyV) is a ubiquitous virus strictly associated with Merkel cell carcinoma (MCC), a rare and aggressive skin cancer. MCPyV oncogenic properties are associated mainly with early protein expression, integration, and LT truncation.

Analysis of the DNA damage response in living cells [PDF]

, 2007
DNA lesions arising from environmental and endogenous sources induce various cellular responses including cell cycle arrest, DNA repair and apoptosis. Although detailed insights into the biochemical mechanisms and composition of DNA repair pathways have ...

DNA polymerase α (swi7) and the flap endonuclease fen1 (rad2) act together in the s-phase alkylation damage response in S. pombe [PDF]

, 2012
Polymerase α is an essential enzyme mainly mediating Okazaki fragment synthesis during lagging strand replication. A specific point mutation in Schizosaccharomyces pombe polymerase α named swi7-1, abolishes imprinting required for mating-type switching ...

Global Real‐World Outcomes of Olaparib in Metastatic Castration‐Resistant Prostate Cancer Patients With Homologous Recombination Repair Alterations

International Journal of Cancer, EarlyView.
ABSTRACT Evidence to guide the treatment for patients with metastatic castration‐resistant prostate cancer (mCRPC) and Homologous Recombination Repair (HRR) gene alterations outside of clinical trials remains limited. This was an observational, cohort study, including mCRPC patients with tumor harboring HRR alterations, progressed on a prior androgen ...
