Insights

Researchers are investigating how vitamin D (1,25(OH)2D3) and its receptor (VDR) control genes, focusing on myeloid cell differentiation and identifying new VDR target genes.

Area of Science:

  • Molecular Biology
  • Endocrinology
  • Cell Biology

Background:

  • Vitamin D is a crucial nutrient with hormonal functions.
  • The vitamin D receptor (VDR) is a nuclear receptor that regulates gene expression.
  • Understanding VDR's role is key to comprehending cellular processes like growth and differentiation.

Purpose of the Study:

  • To elucidate the molecular mechanism of action of 1,25(OH)2D3 and VDR in gene regulation.
  • To define the function and structure of the VDR.
  • To identify and characterize VDR target genes involved in myeloid differentiation.

Main Methods:

  • Molecular level examination of VDR actions.
  • Isolation and characterization of VDR target genes.
  • Analysis of VDR as a ligand-regulated transcription factor.

Main Results:

  • Summaries of recent findings from both VDR function and target gene identification tracks.
  • Progress in understanding VDR's role in gene control.
  • Identification of specific VDR target genes relevant to myeloid differentiation.

Conclusions:

  • A comprehensive understanding of VDR's function as a transcription factor is essential.
  • This knowledge facilitates the study of VDR's actions on newly discovered genes.
  • The research contributes to understanding vitamin D's impact on cellular differentiation, particularly in myeloid cells.

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.
Master Transcription Regulators02:23

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Positive Regulator Molecules

Mitotic cell division results in daughter cells that exactly resemble the parent cell. However, errors in the DNA replication or distribution of genetic material may lead to genetic mutations that may be passed down to every new cell formed from the resulting abnormal cell. Propagation of such mutant cells is restricted through checkpoint mechanisms present at different stages of the cell cycle. These checkpoints involve regulator molecules that either promote or demote cell cycle events.
Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
