Summary
Alternative splicing generates diverse protein isoforms, impacting cancer cell growth and apoptosis. Anticancer drugs can manipulate splicing, offering potential for novel cancer therapies by promoting pro-apoptotic forms.
Area of Science:
- Molecular Biology
- Cancer Research
- Pharmacology
Background:
- Pre-messenger RNA (mRNA) alternative splicing produces distinct protein isoforms with varied functions.
- Altered gene expression in cell growth and apoptosis is characteristic of cancer cells.
- Alternative splicing patterns of key cancer-related genes are crucial for understanding and treating cancer.
Purpose of the Study:
- To review current knowledge on alternative splicing in important cancer-related genes.
- To discuss the generation of functionally distinct protein isoforms through alternative splicing.
- To explore the role of anticancer drugs in modulating alternative splicing patterns and their therapeutic potential.
Main Methods:
- Review of existing literature on alternative splicing in cancer.
- Analysis of splicing patterns and resulting protein isoforms.
- Examination of anticancer drug mechanisms in modulating gene splicing.
Main Results:
- Chemotherapy resistance can arise from altered expression of anti-apoptotic or pro-apoptotic isoforms.
- Anticancer drugs can either induce pro-apoptotic isoforms (sensitizing cells) or anti-apoptotic isoforms (conferring resistance).
- Specific examples of gene splicing modulation by anticancer drugs are discussed.
Conclusions:
- Alternative splicing plays a significant role in cancer development and treatment.
- Anticancer drugs can modulate alternative splicing, influencing therapeutic outcomes.
- Shifting splicing towards pro-apoptotic isoforms presents a promising therapeutic strategy for cancer treatment.

RNA Splicing
61.8K
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
27.2K
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...

What is Gene Expression?
12.4K
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is comprised of nucleotides and proteins are comprised of amino acids, a mediator is required to convert the information encoded in DNA into proteins. This mediator is the messenger RNA (mRNA). mRNA copies the blueprint from DNA by a process called transcription. In eukaryotes, transcription occurs in the nucleus by complementary base-pairing with the DNA template. The mRNA is then...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
