Abstract

Insights

Circular RNAs (circRNAs) promote glioblastoma by upregulating circENTPD7. This molecule enhances tumor cell proliferation and motility by interacting with miR-101-3p and ROS1, impacting patient survival.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Circular RNAs (circRNAs) are implicated in human cancers, including glioblastoma.
  • Mechanisms linking circRNAs to glioblastoma pathogenesis remain largely unknown.
  • Investigating circRNA roles is crucial for understanding glioblastoma progression.

Purpose of the Study:

  • To elucidate the role of circRNAs in glioblastoma pathogenesis.
  • To identify specific circRNAs involved in glioblastoma progression.
  • To explore the molecular mechanisms underlying circRNA function in glioblastoma.

Main Methods:

  • CircRNA microarray analysis to detect dysregulated circRNAs in glioblastoma.
  • Cell proliferation assays (CCK-8) and clone formation tests to assess cellular growth.
  • Bioinformatic predictions, dual-luciferase reporter assays, and RNA-RNA pulldown assays to confirm molecular interactions.

Main Results:

  • circENTPD7 (hsa_circ_0019421) was significantly upregulated in glioblastoma tissues.
  • High circENTPD7 expression correlated with poor overall survival in glioblastoma patients.
  • Knockdown of circENTPD7 suppressed glioblastoma cell proliferation and motility.
  • circENTPD7 functions as a sponge for miR-101-3p, regulating ROS1 expression and promoting tumor growth.

Conclusions:

  • circRNA circENTPD7 promotes glioblastoma cell proliferation and motility.
  • The mechanism involves the regulation of the miR-101-3p/ROS1 axis.
  • circENTPD7 represents a potential therapeutic target for glioblastoma.

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.

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 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,...

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

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...
