Insights

Altered microRNA (miRNA) expression drives human cancers. Understanding miRNA regulation in solid tumors is crucial for developing targeted cancer therapies and biomarkers.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • MicroRNAs (miRNAs) are key post-transcriptional regulators of gene expression.
  • Dysregulated miRNA expression is implicated in the initiation and progression of human cancers.
  • Current understanding of miRNA regulatory mechanisms in cancer remains incomplete.

Purpose of the Study:

  • To elucidate the regulatory mechanisms behind altered miRNA expression in cancer.
  • To investigate the impact of miRNA manipulation on the pathogenesis of solid tumors.
  • To highlight the clinical potential of cancer-relevant miRNAs as therapeutic targets or biomarkers.

Main Methods:

  • Bioinformatic analysis of miRNA expression profiles.
  • Experimental validation of miRNA regulatory pathways.
  • In vitro and in vivo models of solid cancer.

Main Results:

  • Identification of specific regulatory pathways controlling miRNA expression in various solid cancers.
  • Demonstration of miRNA's significant role in cancer cell proliferation, invasion, and metastasis.
  • Correlation between specific miRNA expression patterns and clinical outcomes.

Conclusions:

  • Elucidating miRNA regulatory mechanisms provides critical insights into cancer pathogenesis.
  • Targeting aberrant miRNA expression offers a promising strategy for novel cancer therapies.
  • Cancer-specific miRNAs hold potential as valuable biomarkers for diagnosis and prognosis.

MicroRNAs01:22

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 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...

lncRNA - Long Non-coding RNAs02:39

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...

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

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...
