Insights

A new program, miRCuit, analyzes regulatory molecular circuits in breast cancer. It identified key molecules like lncRNA CASC15, miR-130b-3p, and TF KLF5, advancing precision medicine for cancer.

Area of Science:

  • Molecular biology
  • Systems medicine
  • Genomics

Background:

  • Understanding regulatory molecular circuits is crucial for breast cancer precision medicine.
  • Transcription factors (TFs), microRNAs (miRNAs), and long non-coding RNAs (lncRNAs) are key regulators of gene expression.
  • These molecules form the basis of regulatory circuits influencing health and disease.

Purpose of the Study:

  • To develop a computational tool for analyzing regulatory molecular circuits.
  • To identify novel regulatory circuits involved in breast cancer development and progression.
  • To advance systems medicine approaches for breast cancer research.

Main Methods:

  • Development of the miRCuit program for constructing regulatory elements (mRNA, miRNA, lncRNA, TFs).
  • Analysis of gene expression profiling data from 179 invasive ductal breast carcinoma and 51 normal tissues.
  • Identification and characterization of different regulatory circuit types.

Main Results:

  • The miRCuit program successfully constructed 10 types of regulatory elements.
  • Eight circuit types and two special types were identified in breast cancer samples.
  • A specific circuit involving lncRNA CASC15, miR-130b-3p, and TF KLF5 was highlighted for its role in breast cancer.

Conclusions:

  • The study advances the understanding of regulatory molecules in breast cancer.
  • The miRCuit program provides a new tool for constructing regulatory circuits.
  • Findings support potential applications in deciphering disease pathogenesis and advancing precision oncology.

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...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Cancer-Critical Genes I: Proto-oncogenes

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...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
