Summary
Protein S-nitrosylation, a key cellular signaling process, is crucial for cell functions. Its dysregulation is linked to cancer development, progression, and treatment resistance, highlighting the need for targeted therapies.
Area of Science:
- Biochemistry
- Molecular Biology
- Cancer Research
Background:
- Protein S-nitrosylation is a critical post-translational modification involving nitric oxide (NO) and protein cysteine thiols.
- This modification regulates vital cellular processes such as transcription, DNA repair, and apoptosis.
- Dysregulation of S-nitrosylation is increasingly implicated in cancer pathogenesis and therapeutic resistance.
Purpose of the Study:
- To review the dynamic research on S-nitrosylated proteins in cancer.
- To highlight the link between S-nitrosylation status and cancer therapy outcomes.
- To emphasize the need for developing S-nitrosylation-targeted anti-cancer therapeutics.
Main Methods:
- Literature review of current research on protein S-nitrosylation in cancer.
- Analysis of the role of S-nitrosylated proteins in cancer onset, progression, and treatment resistance.
- Synthesis of findings to underscore the therapeutic potential of targeting S-nitrosylation.
Main Results:
- S-nitrosylation plays varied roles in cancer development and progression.
- The modification status is associated with cancer therapy outcomes and resistance mechanisms.
- Significant gaps exist in understanding the full scope of S-nitrosylated proteins in oncology.
Conclusions:

02:04Covalently Linked Protein Regulators
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein.

03:03mTOR 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.

02:23Abnormal 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 daughter...
02:26NF-κB-dependent Signaling Pathway
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

01:33Cancer-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.
