Insights

Pyroptosis, a programmed cell death process, is regulated by post-translational modifications (PTMs). Understanding PTMs offers new therapeutic strategies for cancer and inflammatory diseases.

Area of Science:

  • Cellular biology
  • Immunology
  • Biochemistry

Background:

  • Pyroptosis is a programmed cell death pathway involving gasdermin proteins.
  • It releases immune-stimulating substances, crucial for anti-tumor and anti-pathogen responses.
  • Pyroptosis pathways involve caspases and gasdermin cleavage.

Purpose of the Study:

  • To comprehensively review the influence of post-translational modifications (PTMs) on pyroptosis.
  • To identify PTMs, their modifying enzymes, and their specific roles in pyroptosis.
  • To explore therapeutic applications of PTM regulation in diseases.

Main Methods:

  • Literature review of studies on PTMs and pyroptosis.
  • Analysis of PTMs' effects on protein properties and pyroptosis regulation.
  • Examination of therapeutic potential of PTM modulation.

Main Results:

  • Various PTMs significantly impact pyroptosis activity, stability, and function.
  • Specific PTMs and their enzymes are identified as key regulators.
  • PTMs offer potential targets for treating cancer and inflammatory conditions.

Conclusions:

  • Post-translational modifications are critical regulators of pyroptosis.
  • Targeting PTMs in pyroptosis presents promising therapeutic avenues for diseases.
  • Further research into PTMs can advance pyroptosis-based therapies.

Covalently Linked Protein Regulators

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

Regulated Protein Degradation02:58

Regulated Protein Degradation

It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Regulation of Expression Occurs at Multiple Steps02:24

Regulation of Expression Occurs at Multiple Steps

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...

Regulation of Expression at Multiple Steps

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...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
