SHANK family on stem cell fate and development

Area of Science:

• Neuroscience
• Stem Cell Biology
• Molecular Biology

Background:

• SHANK proteins (SHANK1-3) are crucial postsynaptic scaffolding proteins at glutamatergeric synapses.
• These proteins play a vital role in synaptogenesis and have emerged as key regulators of stem cell fate.
• Previous studies offer a preliminary understanding of SHANK proteins' influence on stem cell behavior.

Purpose of the Study:

• To review the modulation of SHANK gene expression and associated signaling pathways in stem cells.
• To explore the role of SHANK proteins in stem cell self-renewal, proliferation, differentiation, apoptosis, and metabolism.
• To elucidate the intricate mechanisms of SHANK-mediated stem cell fate determination and its clinical applications in stem cell therapy.

Main Methods:

• Literature review focusing on SHANK gene expression and signaling pathways.
• Analysis of studies investigating SHANK protein functions in various stem cell types, including neural stem cells (NSCs), stem cells from apical papilla (SCAPs), and induced pluripotent stem cells (iPSCs).
• Examination of iPSCs and embryonic stem cells (ESCs) as models for neuronal development studies.

Main Results:

• SHANK proteins significantly influence stem cell self-renewal, proliferation, differentiation, apoptosis, and metabolism.
• SHANK gene expression and signaling pathways are modulated, impacting stem cell fate.
• SHANK proteins are integral to neuronal development processes when studied in iPSCs and ESCs.

Conclusions:

• The SHANK protein family plays a critical regulatory role in determining stem cell fate.
• A comprehensive understanding of SHANK-mediated processes is essential for advancing stem cell therapy.
• Further research into SHANK proteins will unlock new therapeutic strategies in regenerative medicine.
