Insights

Ring finger protein 2 (RNF2) acts as an E3 ubiquitin ligase and is implicated in various cancers. Overexpressed RNF2 correlates with cancer progression and resistance, suggesting its potential as a therapeutic target.

Area of Science:

  • Epigenetics and Cancer Biology
  • Molecular Oncology
  • Biochemistry

Background:

  • RNF2 (Ring finger protein 2) is an E3 ubiquitin ligase catalyzing histone H2A monoubiquitination (H2AK119ub).
  • The RNF2 gene is located on human chromosome 1q25.3, with its coding region spanning 9 exons and encoding 336 amino acids.

Purpose of the Study:

  • To review the association between RNF2 and various cancers.
  • To highlight recent RNF2 regulation studies and its role in cancer progression.
  • To discuss RNF2's involvement in cellular signaling pathways and its clinical potential.

Main Methods:

  • Literature review of studies on RNF2 and cancer.
  • Analysis of RNF2 expression levels in different cancer types.
  • Examination of RNF2's role in epigenetic modifications and cellular signaling.

Main Results:

  • Upregulated RNF2 expression is linked to the progression of hepatocellular carcinoma, melanoma, prostate, breast, pancreatic, gastric, and bladder cancers.
  • Elevated RNF2 levels are associated with radioresistance in lung cancer and chemoresistance in ovarian cancer.
  • RNF2's role in epigenetic regulation and its impact on cancer cell behavior are evident across multiple studies.

Conclusions:

  • RNF2 is a significant factor in the pathological progression and clinical features of numerous cancers.
  • RNF2 demonstrates potential as an epigenetic biomarker for cancer detection and prognosis.
  • Targeting RNF2 presents a promising therapeutic strategy for various cancer types.

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

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...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

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...
