Insights

MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression. Altered miRNA expression is linked to cancer, with potential roles as oncogenes, tumor suppressors, and biomarkers for hepatocellular tumors.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Context:

  • MicroRNAs (miRNAs) are crucial regulators of gene expression.
  • miRNAs play significant roles in physiological functions and are implicated in tumorigenesis.
  • Specific miRNA expression alterations are directly involved in the carcinogenesis process.

Purpose:

  • To review recent research on miRNAs and hepatocellular tumorigenesis.
  • To elucidate the role of small non-coding RNAs in cancer development.
  • To explore the potential of miRNAs as diagnostic and prognostic markers for hepatocellular tumors.

Summary:

  • miRNAs can function as oncogenes or tumor suppressors.
  • Deregulation of certain miRNAs is associated with specific tumor subtypes.
  • This review consolidates current understanding of miRNA involvement in liver cancer.

Impact:

  • Understanding miRNA involvement in hepatocellular carcinogenesis.
  • Identifying potential miRNA-based biomarkers for early diagnosis and prognosis of liver cancer.
  • Highlighting miRNAs as therapeutic targets in hepatocellular carcinoma.

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 (lncRNA)...

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
