Renal Phosphate Reabsorption in Humans Depends on at Least Three Distinct Transporters Unlike in Mice

open access: yesActa Physiologica, Volume 242, Issue 8, August 2026.
ABSTRACT Aim Kidney excretion of phosphate is the gatekeeper of systemic phosphate homeostasis as evident from inborn and acquired diseases. Renal phosphate transporters are a promising target for phosphate‐lowering drugs, but molecular details of human kidney phosphate handling are largely unknown.

Disruption of Claudin‐2 and Trpv6 Results in Hypocalcemia, Hypercalciuria, and Altered Bone Microarchitecture in Mice

open access: yesActa Physiologica, Volume 242, Issue 8, August 2026.
ABSTRACT Transepithelial calcium absorption occurs via a transcellular or paracellular pathway. The intestinal transcellular pathway relies, at least partially, on the apical calcium channel transient receptor potential vanilloid 6 (TRPV6), whereas paracellular calcium (re)absorption occurs through tight junction proteins, including claudin‐2 (CLDN2 ...

Vitamin D Supplementation to Prevent Post‐Thyroidectomy Hypocalcemia

open access: yesClinical Endocrinology, Volume 105, Issue 2, Page 259-266, August 2026.
ABSTRACT Objective Hypocalcemia is the most common complication following thyroidectomy. Previous studies yielded inconsistent results on whether vitamin D3 prevents postoperative hypocalcemia and were conducted in non‐European countries with different dietary habits and baseline vitamin D levels.

Ein photoschaltbares Vitamin‐D‐Mimetikum mit agonistischer und antagonistischer Aktivität ermöglicht bidirektionale optische Kontrolle von VDR

open access: yesAngewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Vitamin D entfaltet über die Aktivierung des ligandenabhängigen Transkriptionsfaktors Vitamin‐D‐Rezeptor (VDR) komplexe und zellspezifische biologische Wirkungen in verschiedenen Geweben. Das photoschaltbare Vitamin‐D‐Mimetikum 10 wechselt durch Belichtung zwischen VDR‐Antagonisten‐ (E) und Agonisten‐Aktivität (Z) und bietet eine bislang einzigartige ...

An Agonist/Antagonist Photo‐Switchable Vitamin D Mimetic Enables Bidirectional Optical Control of VDR

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 29, 13 July 2026.
Vitamin D exhibits complex and cell‐specific biological effects in multiple tissues via activation of the ligand‐sensing transcription factor vitamin D receptor (VDR). The photo‐switchable vitamin D mimetic 10 transitions between VDR antagonist (E) and agonist (Z) activity upon illumination and offers unprecedented bidirectional optical control over ...

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

open access: yesPediatric Blood &Cancer, Volume 73, Issue 7, July 2026.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

PLGA nanoparticles as a platform for vitamin D-based cancer therapy

open access: yesBeilstein Journal of Nanotechnology, 2015
Poly(lactic-co-glycolic acid) (PLGA) nanoparticles were studied as drug delivery vehicles for calcitriol, the active form of vitamin D3. In vitro effects of calcitriol encapsulated in PLGA nanoparticles were evaluated with respect to free calcitriol on ...

Calcitriol inhibits ROS-NLRP3-IL-1β signaling axis via activation of Nrf2-antioxidant signaling in hyperosmotic stress stimulated human corneal epithelial cells

open access: yesRedox Biology, 2019
Purpose: The activation of ROS-NLRP3-IL-1β signaling axis induced by hyperosmotic stress (HS) has been recognized as a key priming stage of epithelial inflammation in dry eye pathogenesis.

In vitro evaluation of the immunomodulatory and antibacterial activities of calcitriol (1,25-dihydroxy-vitamin D3) as a potential application for aerobic vaginitis treatment - preliminary study results

open access: yesBMC Microbiology
Background Aerobic vaginitis (AV) is a state of abnormal vaginal microbiota, which is associated with increased numbers of aerobic, enteric bacteria and inflammation of the vaginal epithelium.
