Inheritance of Chromatin Structures03:17

Inheritance of Chromatin Structures

7.0K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

The Y Chromosome Determines Maleness02:19

The Y Chromosome Determines Maleness

7.5K
The Y chromosome is a sex chromosome found in several vertebrates and mammals, including humans. In addition to 22 pairs of autosomes, the human males have one X chromosome and one Y chromosome. In these organisms, the presence or absence of the Y chromosome determines the development of male traits.
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size....

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

5.3K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Maintenance of the ES Cell State01:14

Maintenance of the ES Cell State

2.4K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

Negative Regulator Molecules01:23

Negative Regulator Molecules

37.5K
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.

Area of Science:

  • Developmental Biology
  • Stem Cell Biology
  • Cancer Biology

Background:

  • RUNX2, a key transcription factor in bone development, is also implicated in prostate and breast cancer progression.
  • Its role in normal prostate biology and stem cells remained unexamined.

Purpose of the Study:

  • To investigate the role of RUNX2 in normal prostate biology and prostate epithelial stem cells.
  • To determine the effects of RUNX2 on prostate development and stem cell markers.

Main Methods:

  • Enrichment of murine prostate stem cells via non-adherent spheroid formation.
  • Quantitative reverse transcription polymerase chain reaction (RT-qPCR) for gene expression analysis.
  • In vitro and in vivo manipulation of Runx2 expression (knockout and overexpression) in mouse models.

Main Results:

  • Runx2 mRNA levels were elevated in prostate stem cell-enriched spheroids.
  • Runx2 is essential for spheroid formation; its loss reduced stem cell markers, while overexpression was stimulatory.
  • In vivo deletion of Runx2 inhibited prostate tubule growth, maturation, and stem cell marker expression.

Conclusions:

  • RUNX2 plays a significant role in normal prostate development.
  • RUNX2's function in prostate epithelial stem cells likely underlies its importance in prostate development.
