Insights

The vitamin D receptor (VDR) influences genes vital for health and disease, including cancer. Activating VDR may offer therapeutic benefits by targeting specific genomic sites involved in disease pathways.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • The vitamin D receptor (VDR) is a transcription factor regulating genes critical for cellular functions like metabolism, bone health, growth, and inflammation.
  • Dysregulation of VDR target genes is implicated in common human diseases, notably cancer.
  • VDR activation by ligands presents a potential therapeutic strategy for these pathological conditions.

Purpose of the Study:

  • To explore the role of VDR and its target genes in disease pathways, particularly cancer.
  • To identify and understand the significance of VDR-binding sites (VDREs) within genomic regulatory modules.
  • To assess the potential therapeutic value of VDR in cancer treatment.

Main Methods:

  • Genome-wide identification of VDR targets using transcriptome analysis.
  • Chromatin immunoprecipitation (ChIP) scans to map VDR-binding sites.
  • In silico screening approaches to identify regulatory modules containing VDREs.

Main Results:

  • Numerous genomic targets of VDR have been identified through various screening methods.
  • Key cancer-related regulatory modules containing VDREs have been pinpointed.
  • These findings highlight the convergence of disease pathways on VDR-regulated genomic elements.

Conclusions:

  • VDR plays a crucial role in cellular processes and its dysregulation is linked to diseases like cancer.
  • Understanding VDR's genomic targets and regulatory modules is essential for developing VDR-based therapies.
  • The identified cancer-related regulatory modules with VDREs hold significant potential for advancing VDR-targeted cancer treatment strategies.

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
Signal Transduction: Overview01:26

Signal Transduction: Overview

Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...
Endocrine Signaling01:45

Endocrine Signaling

Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.

Role of Vitamins in Maintaining Bone Health01:25

Role of Vitamins in Maintaining Bone Health

The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
Calmodulin-dependent Signaling01:16

Calmodulin-dependent Signaling

Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...
