Somatic to iPS Cell Reprogramming

Somatic to iPS Cell Reprogramming

Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

Induced Pluripotent Stem Cells

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Maintenance of the ES Cell State

Maintenance of the ES Cell State

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...

The Retinoblastoma Gene

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Cancer Stem Cells and Tumor Maintenance

Cancer Stem Cells and Tumor Maintenance

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...

Background:

Special AT-rich sequence binding protein-2 (SATB2) is a nuclear matrix protein involved in chromatin remodeling and gene regulation.
SATB2 plays a role in maintaining pluripotency, self-renewal, and epithelial-mesenchymal transition (EMT) in stem cells.

Purpose of the Study:

To investigate the oncogenic role of SATB2 in prostate cancer.
To determine if SATB2 overexpression in normal prostate epithelial cells (PrECs) induces cancer stem cell (CSC) properties.

Main Methods:

SATB2 expression analysis in prostate cancer cell lines and tissues.
Overexpression of SATB2 in PrECs to assess cellular transformation and CSC marker induction.
Chromatin immunoprecipitation (ChIP) assays to identify SATB2 binding targets.

SATB2 knockdown in prostate CSCs to evaluate effects on stemness and malignancy.

Main Results:

SATB2 is highly expressed in prostate cancer cells and CSCs, and elevated in adenocarcinoma tissue compared to normal tissue.
SATB2 overexpression in PrECs induced cellular transformation, colony/spheroid formation, stem cell marker expression (CD44, CD133), pluripotency factors, and EMT.
SATB2 directly binds to promoters of genes regulating pluripotency, cell survival, and proliferation (e.g., BCL-2, MYC, NANOG).
SATB2 knockdown in prostate CSCs reduced spheroid formation, viability, motility, migration, invasion, and reversed the epithelial-mesenchymal transition.

Conclusions:

SATB2 acts as an oncogenic factor in prostate cancer by inducing CSC characteristics.
SATB2 promotes cellular transformation, stemness, and malignant phenotypes in prostate cells.
Targeting SATB2 may offer a therapeutic strategy for prostate cancer treatment.
