Insights

RUVBL1, a histone modifier, is amplified and overexpressed in head and neck squamous cell carcinoma (HNSCC). Its overexpression indicates poor prognosis and promotes cancer cell proliferation, highlighting it as a therapeutic target.

Area of Science:

  • Epigenetics
  • Cancer Biology
  • Molecular Oncology

Background:

  • Epigenetic alterations, including histone modifications, are implicated in various cancers.
  • Understanding the role of epigenetic factors in head and neck squamous cell carcinoma (HNSCC) remains limited.

Purpose of the Study:

  • To identify epigenetic factors contributing to HNSCC development.
  • To investigate the role of RUVBL1 and H2AZ in HNSCC pathogenesis.

Main Methods:

  • Analysis of The Cancer Genome Atlas (TCGA) and single-cell HNSCC data.
  • In vitro experiments to assess the functional role of RUVBL1/H2AZ.

Main Results:

  • RUVBL1 (TIP49a), a component of the TIP60 complex, is amplified and overexpressed in HNSCC.
  • RUVBL1 and histone variant H2AZ are co-overexpressed, regulating key oncogenic transcriptional programs.
  • RUVBL1 overexpression is a poor prognostic marker, predicting reduced survival in HNSCC patients.
  • In vitro studies confirm a pro-proliferative role for RUVBL1/H2AZ in HNSCC cells.

Conclusions:

  • RUVBL1/H2AZ axis plays a critical role in HNSCC tumorigenesis by promoting proliferation and invasion.
  • RUVBL1 is inversely correlated with differentiation and positively correlated with oncogenic programs in HNSCC.
  • RUVBL1 represents a potential therapeutic target for HNSCC treatment.

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...

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...

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,...

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.

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
