Summary
S100A10 protein expression is regulated by grainyhead-like 2 (GRHL2) transcription factor. GRHL2 directly binds to the S100A10 gene, influencing its transcription and cellular processes like ECM degradation and neurotransmission.
Area of Science:
- Molecular Biology
- Cellular Biology
- Biochemistry
Background:
- S100A10 is a calcium-binding protein involved in extracellular matrix degradation and neurotransmitter binding.
- Dysregulation of S100A10 is implicated in tumor progression and depressive symptoms.
- Strict control of S100A10 gene expression is crucial for cellular homeostasis.
Purpose of the Study:
- To review known regulators of S100A10 expression.
- To identify novel transcription factors controlling S100A10 expression.
- To elucidate the mechanism of S100A10 regulation by grainyhead-like 2 (GRHL2).
Main Methods:
- Literature review of S100A10 regulation.
- In silico analysis to identify transcription factor binding sites.
- Chromatin immunoprecipitation (ChIP) assays.
- Luciferase reporter assays.
Main Results:
- GRHL2 binding sites were identified in the first intron of the S100A10 gene.
- GRHL2 was shown to directly bind to these sites.
- GRHL2 binding significantly impacts S100A10 gene transcription.
Conclusions:
- GRHL2 is a novel regulator of S100A10 expression.
- The identified regulatory mechanism provides new insights into S100A10's role in disease.
- Understanding S100A10 regulation is vital for therapeutic strategies targeting cancer and neurological disorders.

2.9K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

7.3K
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...

The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

2.7K
Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...
