Insights

OIP5-AS1, a long non-coding RNA, plays a critical role in cancer development by regulating cell cycles and acting as a competing endogenous RNA. Its elevated expression in most cancers highlights its potential as a cancer biomarker.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • OIP5-AS1 is a long non-coding RNA (lncRNA) highly expressed in the nervous system.
  • This lncRNA is implicated in neoplastic transformation and regulates cell cycle progression.
  • OIP5-AS1 functions as a competing endogenous RNA (ceRNA) for numerous microRNAs (miRNAs).

Purpose of the Study:

  • To comprehensively review and synthesize existing research on the function of OIP5-AS1 in various cancer types.
  • To consolidate findings on OIP5-AS1's role in carcinogenesis, including its interaction with miRNAs and modulation of epithelial-mesenchymal transition (EMT).

Main Methods:

  • Literature review and compilation of research papers evaluating OIP5-AS1 function in cancer.
  • Analysis of OIP5-AS1's molecular mechanisms, including its role as a ceRNA and its impact on cellular processes.

Main Results:

  • OIP5-AS1 expression is elevated in most neoplastic tissues, with exceptions like multiple myeloma.
  • Conflicting expression data exists for OIP5-AS1 in bladder, gastric, and lung cancers.
  • OIP5-AS1 influences carcinogenesis through pathways including EMT and miRNA sponging.

Conclusions:

  • OIP5-AS1 is a significant lncRNA involved in multiple cancer types.
  • Further research is needed to clarify its role in specific cancers with conflicting expression data.
  • OIP5-AS1's functions as a ceRNA and regulator of EMT present therapeutic and diagnostic opportunities.

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

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...

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...

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...

Non-LTR Retrotransposons

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...
