Insights

Long non-coding RNAs (lncRNAs) interact with proteins to perform functions. Understanding these interactions, like CCAT2 with protein complexes, aids novel cancer therapeutics development.

Area of Science:

  • Molecular Biology
  • Genetics
  • Cancer Research

Background:

  • Long non-coding RNAs (lncRNAs) are crucial regulators of cellular processes.
  • Protein-lncRNA interactions are key to understanding lncRNA function.
  • The 8q24 cancer amplicon harbors genes implicated in tumorigenesis.

Purpose of the Study:

  • To investigate the functional interactions of the lncRNA CCAT2.
  • To understand how CCAT2 reprograms cancer metabolism.
  • To explore the allele-specific interactions of CCAT2 with protein complexes.

Main Methods:

  • Allele-specific interaction analysis.
  • Protein complex identification.
  • Cancer metabolism assays.

Main Results:

  • CCAT2 directly interacts with a specific protein complex.
  • This interaction is allele-specific.
  • CCAT2 binding reprograms cancer cell metabolism.

Conclusions:

  • CCAT2 plays a significant role in cancer metabolism regulation through direct protein interactions.
  • Targeting CCAT2-protein complex interactions may offer novel therapeutic strategies for cancer.

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...

Protein Networks02:26

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

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...

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...
