Insights

Alternative splicing (AS) regulates cell death, impacting cancer development. Targeting AS-mediated regulatory cell death (RCD) offers potential new cancer therapies.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Oncology

Background:

  • Alternative splicing (AS) generates protein diversity from a single gene via the spliceosome.
  • Dysregulation of regulatory cell death (RCD) pathways like apoptosis and ferroptosis is linked to cancer.
  • Aberrant AS events involving spliceosome components and splicing factors can influence RCD and contribute to tumorigenesis.

Purpose of the Study:

  • To review the role of alternative splicing in tumor regulatory cell death.
  • To elucidate the mechanisms by which AS modulates various RCD modes.
  • To summarize potential clinical applications of targeting AS-RCD pathways in cancer therapy.

Main Methods:

  • Literature review focusing on alternative splicing and regulatory cell death.
  • Analysis of molecular mechanisms linking AS to different RCD pathways.
  • Synthesis of current research on clinical applications of AS-RCD targeting.

Main Results:

  • AS plays a significant role in modulating diverse RCD pathways.
  • Specific AS events and splicing factors are implicated in cancer progression via RCD.
  • Targeting AS-RCD interactions presents a promising therapeutic strategy for cancer.

Conclusions:

  • Alternative splicing is a key regulator of tumor cell death pathways.
  • Understanding AS-mediated RCD offers mechanistic insights into tumorigenesis.
  • Targeting AS-RCD axes holds potential for novel cancer treatments.

RNA Splicing01:32

RNA Splicing

Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

Alternative RNA Splicing

Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

Chromatin Structure Regulates pre-mRNA Processing

In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.
The chromatin structure, especially...

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
