Urinary adenosine 3' 5' - cyclic monophosphate (cyclic AMP) was assessed by a competitive protein binding method in 19 patients with primary hyperparathyroidism (PHPT) and in 15 control subjects. The mean value of 6.6 +/- S.E. 0-64 muM per 24 hours for the patients with PHPT was higher (P less than 0-001) than the mean control value of 3-2 +/- 0-24 muM per 24 hours. In all hypercalcaemic patients without renal insufficiency, urinary cyclic AMP excretion was more than 4 muM per 24 hours and decreased in the 15 patients investigated after parathyroidectomy. In a normocalcaemic hyperparathyroid patient and in three hyperparathyroid patients with renal insufficiency, urinary cyclic AMP was less than 4 muM per 24 hours.

A responsive cocktail nano-strategy breaking the immune excluded state enhances immunotherapy for triple negative breast cancer.

The exclusion of immune cells from the tumor can limit the effectiveness of immunotherapy in triple negative breast cancer (TNBC). The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway plays a crucial role in priming adaptive anti-tumor immunity through the production of type I interferons (IFNs), facilitating the maturation of dendritic cells (DCs) and the function of T cells. Although the increased expression of programmed death-ligand 1 (PD-L1) upon STING activation is favorable for amplifying the efficacy of immune checkpoint inhibitors (ICIs) and realizing combination therapy, the penetration barrier remains a major obstacle.

Middle-aged obesity, characterized by excessive fat accumulation and systemic energy imbalance, often precedes various health complications. Recent research has unveiled a surprising link between DNA damage response and energy metabolism. Here, we explore the role of Eepd1, a DNA repair enzyme, in regulating adipose tissue function and obesity onset.

The microenvironment tends to be immunosuppressive during tumor growth and proliferation. Immunotherapy has attracted much attention because of its ability to activate tumor-specific immune responses for tumor killing. The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is an innate immune pathway that activates antitumor immunity by producing type I interferons.

CMPK2 promotes NLRP3 inflammasome activation via mtDNA-STING pathway in house dust mite-induced allergic rhinitis.

Clin Transl Med

January 2025

Allergy Center, Department of Otolaryngology, Affiliated Eye and ENT Hospital, Fudan University, Shanghai, China.

Background: House dust mite (HDM) is the leading allergen for allergic rhinitis (AR). Although allergic sensitisation by inhaled allergens renders susceptible individuals prone to developing AR, the molecular mechanisms driving this process remain incompletely elucidated.

Objective: This study aimed to elucidate the molecular mechanisms underlying HDM-induced AR.
