Insights

Post-translational modifications (PTMs) significantly impact heterogeneous nuclear ribonucleoproteins (HNRNPs) functions in cancer. Understanding these PTMs offers new therapeutic strategies for cancer treatment.

Area of Science:

  • Molecular Biology
  • Cancer Research
  • Biochemistry

Background:

  • Heterogeneous nuclear ribonucleoproteins (HNRNPs) are crucial RNA-binding proteins involved in gene regulation.
  • Their roles in cancer progression, including RNA splicing, transcription, and translation, are increasingly recognized.
  • The specific modulation of HNRNPs in cancer remains incompletely understood.

Purpose of the Study:

  • To review the current evidence on how post-translational modifications (PTMs) regulate HNRNP functions.
  • To explore the involvement of dysregulated PTMs of HNRNPs in cancer development.
  • To highlight the potential of PTMs on HNRNPs as therapeutic targets.

Main Methods:

  • Literature review synthesizing existing research on HNRNPs and PTMs.
  • Analysis of studies utilizing techniques like LC-MS/MS to identify PTMs on HNRNPs.
  • Compilation of evidence linking HNRNP PTMs to gene regulation and cancer.

Main Results:

  • HNRNPs are extensively and significantly targeted by various PTMs.
  • PTMs are key regulators of HNRNP functions in physiological and pathological processes.
  • Several PTMs are implicated in HNRNP regulation within the context of cancer.

Conclusions:

Regulation of Expression at Multiple Steps01:23

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...

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...

Covalently Linked Protein Regulators02:04

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....

Translational Regulation01:29

Translational Regulation

Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...

Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
