Summary
This study identified 12 deleterious AKT1 gene mutations, including four at conserved residues, that may impact protein function. One mutation (R273Q) is linked to liver cancer, aiding disease diagnosis and drug development.
Area of Science:
- Genetics and Molecular Biology
- Bioinformatics and Computational Biology
Background:
- The AKT1 gene encodes a serine/threonine kinase crucial for cell apoptosis, angiogenesis, metabolism, and proliferation.
- AKT1 gene mutations are implicated in various cancers and genetic disorders like Proteus and Cowden syndromes.
Purpose of the Study:
- To identify deleterious missense single nucleotide polymorphisms (SNPs) in the AKT1 gene.
- To predict the functional and structural impact of these AKT1 SNPs using computational tools.
Main Methods:
- In silico analysis of the human AKT1 gene to identify deleterious missense SNPs.
- Assessment of SNP impact on AKT1 protein structure and function.
- Analysis of the association between identified SNPs and cancer types.
Main Results:
- Identified 12 highly deleterious AKT1 SNPs affecting protein structure and function.
- Four SNPs (G157R, G159V, G336D, H265Y) are located at conserved residues.
- SNP G157R may impact ligand binding; SNP R273Q is associated with liver cancer.
Conclusions:
- Findings support the utility of computational approaches for SNP identification and disease association studies.
- Identified SNPs can inform pharmacogenomics and molecular diagnostics for AKT1-related diseases.
- This research aids in developing targeted inhibitors for the AKT1 oncogene.

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.

mTOR Signaling and Cancer Progression
3.8K
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.

PI3K/mTOR/AKT Signaling Pathway
3.7K
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...
