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 ...

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 ...

Roles of Nicotinamide Adenine Dinucleotide (NAD+) in Biological Systems

Challenges, 2018
NAD+ has emerged as a crucial element in both bioenergetic and signaling pathways since it acts as a key regulator of cellular and organism homeostasis. NAD+ is a coenzyme in redox reactions, a donor of adenosine diphosphate-ribose (ADPr) moieties in ADP-

Combination of Lenvatinib and Antibiotics: A Potential Approach to Enhance Sensitivity in Differentiated Thyroid Cancer

International Journal of Cancer, EarlyView.
Although lenvatinib is the current first‐line therapy for radioiodine‐refractory differentiated thyroid carcinoma, its use is limited by severe side effects and reduced sensitivity. Here, the authors assessed the potential of sensitizing differentiated thyroid carcinoma tumor cells with limited lenvatinib responsiveness through the administration of ...

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 ...

α2,3‐Sialyltransferase (ST3Gal1) regulates endometrioid‐type epithelial ovarian cancer cell migration and invasion via VEGF‐R2/JAK2/STAT3 signaling cascades

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To investigate the role of ST3 β‐galactoside α‐2,3‐sialyltransferase 1 (ST3Gal1) and vascular endothelial growth factor receptor 2 (VEGF‐R2) in endometrioid‐type epithelial ovarian cancer (E‐OC) because aberrant α2,3‐sialylation mediated by ST3Gal1 and VEGF‐R2‐related angiogenesis is linked with tumor progression. Methods ST3Gal1 and

Nitrosative Stress as a Modulator of Inflammatory Change in a Model of Takotsubo Syndrome

JACC: Basic to Translational Science, 2018
Summary: Previous studies have shown that patients with Takotsubo syndrome (TS) have supranormal nitric oxide signaling, and post-mortem studies of TS heart samples revealed nitrosative stress.

Menopausal hormone therapy and comprehensive postmenopausal care in gynecologic cancer survivors: A position paper from the FIGO Committee on Women at Menopausal Age

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Recent advances in cancer screening, diagnosis, and treatment have greatly improved survival rates among women with gynecologic cancers. More survivors now live long enough to experience treatment‐related menopause. Vasomotor symptoms, genitourinary syndrome of menopause, sexual dysfunction, sleep issues, and long‐term risks from estrogen ...

The role of human microbiota in breast cancer pathogenesis and treatment

iMeta, EarlyView.
The human microbiota contributes to breast cancer pathogenesis and treatment response through interactions involving the oral, gut, and breast microbial niches. (Left) Multi‐site dysbiosis is characterized by altered microbial composition and abundance across different anatomical sites.
