Genomics

37.4K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

6.4K
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...

Proteomics01:33

Proteomics

7.9K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

3.9K
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...

Epistasis Analysis01:09

Epistasis Analysis

5.2K
Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway. The...

  • Bioinformatics
  • Systems Biology
  • Genomics

Background:

  • Pathway analysis is crucial for interpreting large-scale omics data.
  • Common issues include database limitations and misinterpretation of pathway relevance, leading to "pathway fails."
  • The Tumor Necrosis Factor (TNF) pathway exemplifies multifunctionality beyond its original annotation.

Purpose of the Study:

  • To broadly evaluate pathway analysis interpretation methods.
  • To clarify ideal use-case scenarios for embedding-based, semantic similarity-based, and network-based approaches.
  • To provide guidance for aligning research objectives with appropriate pathway analysis methods.

Main Methods:

  • Review and evaluation of different pathway analysis interpretation approaches.
  • Assessment of strengths (e.g., visualization, ease of use) and limitations (e.g., data redundancy, database compatibility).
  • Analysis of contextual examples, such as the TNF pathway.

Main Results:

  • Different interpretation methods have distinct strengths and weaknesses.
  • Input quality and method selection are critical for biologically meaningful results ("garbage in, garbage out").
  • Areas for development include standardization, scalability, and data integration.

Conclusions:

  • Choosing the correct pathway analysis interpretation method is vital for reliable biological insights.
  • Addressing limitations and advancing interpretation techniques will enhance the utility of pathway analysis.
  • Improved pathway analysis supports progress in systems biology and personalized medicine.
