Pharyngeal and Cervical Cancer Incidences Significantly Correlate with Personal UV Doses Among Whites in the United States [PDF]

open access: yes, 2014
Because we found UV-exposed oral tissue cells have reduced DNA repair and apoptotic cell death compared with skin tissue cells, we asked if a correlation existed between personal UV dose and the incidences of oral and pharyngeal cancer in the United ...

Familial hypomagnesaemia, Hypercalciuria and Nephrocalcinosis associated with a novel mutation of the highly conserved leucine residue 116 of Claudin 16 in a Chinese patient with a delayed diagnosis: A case report [PDF]

open access: yes, 2018
Background: Sixty mutations of claudin 16 coding gene have been reported in familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) patients. Recent investigations revealed that a highly conserved glycine-leucine-tryptophan (115G-L-W117)

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.

The role of vitamin D receptor signaling in hair follicle health and alopecia: Current understanding and therapeutic implications

open access: yesJournal of Cell Communication and Signaling, Volume 20, Issue 1, March 2026.
The vitamin D receptor (VDR) regulates hair follicle biology through ligand‐dependent and ligand‐independent mechanisms by heterodimerizing with retinoid X receptor, recruiting coactivator complexes, and activating target genes including Wnt inhibitors, hair keratins, and cell cycle regulators.

Effect of Calcitriol on Differentiation of Periodontal Ligament Stem Cells to Osteoblasts [PDF]

open access: yes, 2016
Background: Periodontium may be able to respond to injuries by regeneration via the function of stem cells. Objectives: This study sought to assess the differentiation of human periodontal ligament stem cells (PDLSCs) into osteoblasts in standard ...

Calcitriol Inhibits HCV Infection via Blockade of Activation of PPAR and Interference with Endoplasmic Reticulum-Associated Degradation

open access: yesViruses, 2018
Vitamin D has been identified as an innate anti-hepatitis C virus (HCV) agent but the possible mechanisms for this issue remain unclear. Here, we clarified the mechanisms of calcitriol-mediated inhibition of HCV infection.

Primary Hyperparathyroidism With Brown Tumor—A Case Mistaken as Non‐Ossifying Fibroma Resolved by Biochemical and Radiological Correlation

open access: yesClinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Primary hyperparathyroidism (PHPT) is uncommon in the pediatric population and rarely presents with overt skeletal complications such as brown tumors. This case study describes a 16‐year‐old female who initially presented with abdominal pain and was subsequently found to have severe hypercalcemia (serum calcium 16.4 mg/dL) and markedly ...
