Summary
This summary is machine-generated.Colorectal cancer progression involves oxidative stress and inflammation, linked by the ROS-NF-κB-MMP-9 pathway. MMP-9 shows high predictive value for CRC, suggesting it as a key diagnostic marker.
Area Of Science
- Oncology
- Biochemistry
- Molecular Biology
Background
- Colorectal cancer (CRC) involves complex interactions between inflammation, oxidative stress, and extracellular matrix remodeling.
- The reactive oxygen species (ROS)-nuclear factor kappa B (NF-κB)-matrix metalloproteinase-9 (MMP-9) axis is significant in CRC invasion and metastasis.
- Understanding this axis is crucial for developing targeted therapies.
Purpose Of The Study
- To analyze advanced oxidation protein products (AOPPs), NF-κB expression, and MMP-9 activity in CRC tissues.
- To investigate the correlation between oxidative stress markers and MMP-9 activity.
- To evaluate MMP-9 as a potential diagnostic and theranostic marker for CRC.
Main Methods
- Analysis of AOPPs, NF-κB, and MMP-9 in tumor, adjacent, and healthy colon tissues from 50 CRC patients.
- Utilized ELISA, spectrophotometry, and indirect immunofluorescence for biochemical analyses.
- Correlated marker levels with clinical data and disease progression.
Main Results
- Significantly elevated AOPPs, NF-κB, and MMP-9 in tumor tissues compared to controls.
- Adjacent tissues showed increased NF-κB and MMP-9 compared to healthy tissues.
- AOPP levels strongly correlated with MMP-9 activity; MMP-9 had the highest predictive value for CRC.
Conclusions
- The ROS-NF-κB-MMP-9 axis is integral to colorectal cancer progression, particularly in T2-T3 stages.
- MMP-9 emerges as a promising diagnostic and theranostic marker for CRC.
- Targeting this pathway offers potential therapeutic strategies for CRC invasion and recurrence.

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.

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...
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.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
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...
