Non-LTR Retrotransposons03:18

Non-LTR Retrotransposons

13.5K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Mechanisms of Retrovirus-induced Cancers

7.1K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

6.5K
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

5.3K
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...

Area of Science:

  • Oncology
  • Virology
  • Immunology

Background:

  • Epstein-Barr virus (EBV) latent membrane protein 1 (LMP1) is crucial in EBV-associated malignancies.
  • LMP1 activation of NF-κB and other growth pathways contributes to lymphomagenesis.
  • LMP1 plays a key role in EBV-driven B-cell transformation.

Purpose of the Study:

  • To review recent advancements in understanding LMP1 signaling.
  • To discuss LMP1-induced host dependency factors.
  • To explore mouse models of LMP1 lymphomagenesis and immunotherapy.

Main Methods:

  • Review of recent scientific literature on LMP1.
  • Analysis of LMP1 signaling pathways.
  • Examination of mouse models and therapeutic strategies.

Main Results:

  • LMP1 mimics CD40 signaling, activating critical cell growth and survival pathways like NF-κB.
  • LMP1 expression in immunosuppressed mice leads to fatal lymphoproliferative disease.
  • LMP1 is implicated in B-cell transformation and various human cancers.

Conclusions:

  • LMP1 is a significant driver of EBV-associated cancers.
  • Further research into LMP1 signaling and targeted therapies is warranted.
  • Understanding LMP1's role is key for developing effective anti-cancer strategies.
