Genetic Ablation of CD38 Protects against Western Diet-Induced Exercise Intolerance and Metabolic Inflexibility. [PDF]

PLoS ONE, 2015
Nicotinamide adenine dinucleotide (NAD+) is a key cofactor required for essential metabolic oxidation-reduction reactions. It also regulates various cellular activities, including gene expression, signaling, DNA repair and calcium homeostasis ...

Research progress on the role of inflammatory mediators in the pathogenesis of epilepsy

Ibrain, Volume 11, Issue 1, Page 44-58, Spring 2025.
In the central nervous system, activated immune cells lead to the overproduction of inflammatory mediators through the corresponding signal pathway. Under the stimulation of inflammatory factors, neuroinflammation ultimately occurs. Overexpression of inflammatory mediators and activated immunocytes plays an important role in the emergence and ...

Cyclic ADP-Ribose and Calcium Signaling in Eggs

Neurosignals, 1996
Cyclic ADP-ribose is a cyclic nucleotide with Ca2+ signaling functions. It was first discovered in sea urchin eggs and has since been shown to be active in a variety of cells. Another Ca2+ release mechanism recently described in the eggs is mediated by nicotinic acid dinucleotide phosphate, a derivative of NADP+. This article summarizes current results

ID3 deficiency alters chromatin accessibility at DSB sites and enhances vulnerability to HDAC inhibition

International Journal of Cancer, EarlyView.
What's New? Errors in DNA double‐strand break (DSB) repair can lead to mutations, chromosomal instability, and ultimately cancer. Inhibitor of DNA‐binding 3 (ID3), a transcriptional repressor, is crucial to promoting DSB repair and helping maintain genome stability. Here, the authors investigated ID3 regulation of DNA repair via chromatin accessibility

Ovarian Cancer: Epidemiology, Disease Mechanisms, New Diagnosis and Treatment Strategies, and Research Directions

iNew Medicine, EarlyView.
ABSTRACT Ovarian cancer (OC) continues to be the deadliest gynecological malignancy and a significant cause of cancer‐related mortality among women worldwide. Standard treatment strategies typically entail platinum‐based chemotherapy in conjunction with cytoreductive surgery.

Beyond Tradition: An Integrated Toxicological, Ecological, and Public Health Perspective on Aristolochic Acids

Journal of Applied Toxicology, EarlyView.
ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...

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 ...

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

Interactions between intracellular Ca2+ stores: Ca2+ released from the NAADP pool potentiates cADPR-induced Ca2+ release

Brazilian Journal of Medical and Biological Research, 2002
Cells possess multiple intracellular Ca2+-releasing systems. Sea urchin egg homogenates are a well-established model to study intracellular Ca2+ release. In the present study the mechanism of interaction between three intracellular Ca2+ pools, namely the
