Necrosis01:16

Necrosis

4.5K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

siRNA - Small Interfering RNAs

16.8K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

Area of Science:

  • Biochemistry
  • Cell Biology
  • Pharmacology

Background:

  • Ferroptosis, a cell death pathway, contributes to tissue damage in conditions like neurodegeneration and liver injury.
  • Ferroptosis inhibitors show therapeutic promise, and silymarin, a traditional remedy, is used for liver conditions.
  • Silibinin, the active component of silymarin, has potential but its role in ferroptosis is not well understood.

Purpose of the Study:

  • To investigate the effects of silibinin on ferroptosis and ferroptosis-related diseases.
  • To determine if silibinin can protect against ferroptosis-induced cell death and tissue injury.

Main Methods:

  • Cell-based assays using ferroptosis inducers (RSL3, erastin).
  • Measurement of lipid peroxidation and labile iron pool.
  • In vivo studies using glutathione peroxidase 4 (GPX4) knockout mice and renal ischemia-reperfusion models.
  • DPPH assay to assess antioxidant activity.

Main Results:

  • Silibinin inhibited ferroptosis in various cell types induced by RSL3 and erastin.
  • Silibinin reduced lipid peroxidation without altering the labile iron pool.
  • Antioxidant activity of silibinin was confirmed via DPPH assay.
  • Silibinin alleviated liver and kidney tissue injury and ferroptosis in GPX4 knockout mice.
  • Silibinin protected against renal ischemia-reperfusion injury.

Conclusions:

  • Silibinin effectively inhibits cell ferroptosis.
  • Silibinin mitigates ferroptosis-related tissue injuries in vivo.
  • Silibinin demonstrates potential as a therapeutic agent for ferroptosis-related diseases.
