Insights

Researchers identified circVAMP3, a novel circular RNA (circRNA) overexpressed in alveolar rhabdomyosarcoma. Depleting circVAMP3 impairs cell cycle progression, highlighting its role in cancer and potential as a therapeutic target.

Area of Science:

  • Oncology
  • Molecular Biology
  • RNA Biology

Background:

  • Circular RNAs (circRNAs) are implicated in various oncogenic processes.
  • Alveolar rhabdomyosarcoma is a pediatric cancer with limited therapeutic options.

Purpose of the Study:

  • To investigate the role of circVAMP3 in alveolar rhabdomyosarcoma.
  • To explore circVAMP3 as a potential therapeutic target.

Main Methods:

  • Characterization of circVAMP3 expression in alveolar rhabdomyosarcoma cell lines.
  • Analysis of m6A modification patterns in circVAMP3 and its linear counterpart.
  • Assessment of circVAMP3's functional impact on cell cycle progression and AKT pathways upon depletion.

Main Results:

  • circVAMP3 was found to be overexpressed in RH4 cells, a model for alveolar rhabdomyosarcoma.
  • circVAMP3 exhibits a distinct m6A methylation pattern compared to its linear form.
  • Depletion of circVAMP3 led to impaired cell cycle progression and altered AKT signaling.

Conclusions:

  • circVAMP3 is a novel circular RNA regulator in alveolar rhabdomyosarcoma progression.
  • circVAMP3's unique m6A modification suggests differential regulation.
  • circVAMP3 represents a potential therapeutic target for alveolar rhabdomyosarcoma.

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

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...

Positive Regulator Molecules02:39

Positive Regulator Molecules

Mitotic cell division results in daughter cells that exactly resemble the parent cell. However, errors in the DNA replication or distribution of genetic material may lead to genetic mutations that may be passed down to every new cell formed from the resulting abnormal cell. Propagation of such mutant cells is restricted through checkpoint mechanisms present at different stages of the cell cycle. These checkpoints involve regulator molecules that either promote or demote cell cycle events.
