AI Article Synopsis
- The study examines the link between genetic variations in the vitamin D receptor (VDR) gene and the risk of periodontitis among the Taiwanese Han population.
- Ninety-two patients with aggressive periodontitis, 385 with chronic periodontitis, and 163 healthy controls participated, with genetic analysis performed on specific VDR polymorphisms.
- Findings showed that while individual VDR polymorphisms did not correlate with aggressive or chronic periodontitis risk, certain combinations of these polymorphisms were significantly associated with both types of periodontitis.
Article Abstract
Background/purpose: : Genetic polymorphisms in the vitamin D receptor (VDR) gene are related to the immune response and bone metabolism, both of which are implicated in the pathogenesis of periodontitis. This study was to investigate the association between VDR-gene polymorphisms and periodontitis among a Taiwanese Han ethnic population.
Materials And Methods: Ninety-two aggressive periodontitis (AgP), 385 chronic periodontitis (CP) and 163 healthy controls (HC) were recruited from dental clinics. Demographic characteristics and possible confounding factors were obtained using a self-reported questionnaire. The VDR rs731236 (I), rs7975232 (I), rs1544410 (I), and rs2228570 (I) polymorphisms were genotyped using PCR-RFLP methods. Statistical analyses were applied to determine the associations.
Results: The individual VDR polymorphisms were not associated with risk of AgP and CP. The f allele of rs2228570 was related to decreased risk for AgP. Subjects with TAbF (adjusted OR = 7.2, 95% CI = 3.2-7.2, p < 0.0001) or TAbf (adjusted OR = 0.17, 95% CI = 0.05-0.48, p = 0.002) combined polymorphisms were significantly associated with AgP. Subjects with Tabf (adjusted OR = 2.6, 95% CI = 1.8-3.8, p < 0.0001), TAbF (adjusted OR = 4.4, 95% CI = 2.6-8.1, p < 0.0001), TabF (adjusted OR = 0.36, 95% CI = 0.2-0.5, p < 0.0001), or TAbf (adjusted OR = 0.45, 95% CI = 0.3-0.7, p = 0.001) combined polymorphisms were significantly associated with CP.
Conclusion: The study indicates that VDR gene polymorphisms are associated with AgP and CP in a Taiwanese Han population.

CD4+ T cells contribute to antitumor immunity and are implicated in the efficacy of cancer immunotherapies. In particular, CD4+ T helper 2 (Th2) cells were recently found to block spontaneous breast carcinogenesis. However, the antitumor potential of Th2 cells in targeting established breast cancer remains uncertain.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are life-threatening conditions characterized by severe inflammation and respiratory failure. Despite the use of dexamethasone (Dex) in treatment, challenges such as poor solubility and systemic side effects persist, highlighting the need for novel therapeutic approaches. This study introduces an innovative nanoparticle delivery system based on chitosan (CS) and polysialic acid (PSA), engineered via electrostatic assembly, to improve the targeted delivery of Dex to inflamed lung tissues.

Colitis-associated colorectal cancer (CAC), a serious complication of ulcerative colitis (UC), is associated with a poor prognosis. The vitamin D receptor (VDR) is recognized for its protective role in UC and CAC through the maintenance of intestinal barrier integrity and the regulation of inflammation. This study demonstrates a significant reduction in mA-related genes, particularly methyltransferase like 14 (METTL14), in UC and CAC patients and identifies an association between METTL14 and VDR.

At the maternal-fetal interface, tightly regulated levels of retinoic acid (RA), the physiologically active metabolite of vitamin A, are required for embryo implantation and pregnancy success. Herein, we utilize mouse models, primary human cells, and pharmacological tools to demonstrate how depletion of RA signaling via RA receptor (RAR) disrupts implantation and progression of early pregnancy. To inhibit RAR signaling during early pregnancy, BMS493, an inverse pan-RAR agonist that prevents RA-induced differentiation, was administered to pregnant mice during the peri-implantation period.

Background: High prices and other access barriers have contributed to the rise of a market for compounded glucagon-like peptide-1 receptor agonists for weight loss in the United States. This market has not been systematically studied. We conducted a pilot study to assess the prevalence, characteristics, and advertising content of direct-to-consumer providers of compounded glucagon-like peptide-1 products for weight loss in Colorado.
