Lethal Alleles

Lethal Alleles

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

In-vitro Mutagenesis

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Mutagenicity and Carcinogenicity

Mutagenicity and Carcinogenicity

Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

Area of Science:

Genomics
Computational Biology
Systems Biology

Background:

CRISPR-Cas9 technology enables large-scale synthetic lethality (SL) screening.
Current databases lack integrated and annotated combinatorial double knockout (CDKO) SL data.
Diverse SL scoring methods hinder data comparison and utility.

Purpose of the Study:

To develop a comprehensive Synthetic Lethality Knowledge Base (SLKB).
To integrate and standardize data from multiple CDKO SL screening experiments.
To facilitate the comparison and analysis of different SL scoring methods.

Main Methods:

Incorporated data from 11 CDKO experiments across 22 cell lines.
Compiled 16,059 SL gene pairs and 264,424 non-SL gene pairs.
Implemented five distinct SL scoring algorithms: Median (B/NB), sgRNA (B/NB), Horlbeck, GEMINI, and MAGeCK.

Main Results:

The SLKB contains extensive curated SL and non-SL gene pair data.
Analysis revealed significant diversity among the top SL gene pairs identified by different scoring methods (1.21% overlap).
SLKB enables visualization of SL networks, highlighting increased connectivity for SL pairs and shared hub genes between cell lines.

Conclusions:

SLKB addresses limitations in current SL data integration and annotation.
The developed resource provides a standardized platform for analyzing synthetic lethality.
SLKB facilitates deeper insights into gene interactions and potential therapeutic targets through network analysis.
