Abstract

Insights

Enhancer RNAs (eRNAs) are non-coding RNAs that promote cancer progression and regulate genes. Both strands of eRNAs play complex roles in sex hormone pathways, contributing to hormone-dependent cancers.

Area of Science:

  • Molecular Biology
  • Cancer Biology
  • Genetics

Background:

  • Enhancer RNAs (eRNAs) are non-coding transcripts.
  • eRNAs are increasingly recognized for their roles in gene regulation and cancer.
  • Emerging evidence highlights eRNA involvement in sex hormone signaling pathways.

Purpose of the Study:

  • To review and summarize current knowledge on eRNAs in sex hormone-dependent cancers.
  • To elucidate the roles of eRNAs in sex hormone-mediated pathways and cancer progression.

Main Methods:

  • Comprehensive literature review of published articles on eRNAs in sex hormone-dependent cancers.
  • Synthesis and summarization of the identified roles of eRNAs in these cancers.

Main Results:

  • Elevated eRNA expression can promote cancer cell progression.
  • eRNAs participate in both gene activation and repression.
  • eRNAs function at cis and trans loci in androgen receptor signaling, with both sense and antisense strands being significant.

Conclusions:

  • Abnormal eRNA overexpression is predominantly oncogenic, driving cancer progression.
  • Both strands of eRNAs exhibit complex, multifaceted roles in sex hormone-mediated pathways.
  • These eRNA functions are closely linked to the development of sex hormone-dependent tumors.

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...

RNA Polymerase II Accessory Proteins02:36

RNA Polymerase II Accessory Proteins

Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...

Master Transcription Regulators02:23

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

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...
