Insights

MicroRNA-1 (miR-1) functions as a tumor suppressor, regulating cancer hallmarks like proliferation and metastasis. Its downregulation in many cancers highlights its therapeutic potential in developing novel anticancer treatments.

Area of Science:

  • Cancer Biology
  • Molecular Oncology
  • Noncoding RNA Research

Background:

  • Cancer development involves complex genetic and non-genetic variations.
  • Noncoding RNAs, including microRNAs (miRNAs), play crucial roles in cancer pathways.
  • MicroRNA-1 (miR-1) is a conserved miRNA involved in muscle development and acts as a tumor suppressor.

Purpose of the Study:

  • To review the antitumorigenic and therapeutic aspects of miR-1 in cancer.
  • To elucidate how miR-1 regulates tumor development and immunomodulatory functions.
  • To highlight the potential of miR-1 as a therapeutic agent against various cancers.

Main Methods:

  • Review of existing literature on miR-1 in cancer biology.
  • Analysis of studies demonstrating miR-1's role in cancer hallmarks.
  • Examination of miR-1's impact on proliferation, metastasis, apoptosis, angiogenesis, and immune modulation.

Main Results:

  • Downregulation of miR-1 is observed in numerous cancers (lung, breast, liver, prostate, colorectal, pancreatic, medulloblastoma, gastric).
  • miR-1 influences key cancer hallmarks, including proliferation, invasion, metastasis, apoptosis, angiogenesis, chemosensitization, and immune modulation.
  • miR-1 exhibits significant antitumorigenic properties and immunomodulatory functions.

Conclusions:

  • miR-1 acts as a potent tumor suppressor across various cancer types.
  • Restoration or modulation of miR-1 levels holds promise for novel anticancer therapies.
  • miR-1's multifaceted roles in cancer present a promising avenue for therapeutic intervention.

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...

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...

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...

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

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...
