Summary
Genetic alterations in colorectal cancer (CRC) involve NF-kappaB and AP-1 pathways, crucial for cell cycle and apoptosis. Targeting these pathways offers a promising therapeutic strategy for CRC treatment.
Area of Science:
- Oncology
- Molecular Biology
- Cancer Genetics
Background:
- Colorectal cancer (CRC) is a significant health concern, often linked to genetic alterations.
- NF-kappaB and AP-1 signaling pathways play critical roles in regulating cell cycle and apoptosis.
- These pathways can be activated by various external stimuli and are implicated in cancer development.
Purpose of the Study:
- To elucidate the role of NF-kappaB and AP-1 signaling in colorectal cancer progression.
- To investigate the involvement of these pathways in the metastatic transition of CRC.
- To explore the potential of targeting NF-kappaB and AP-1 as a therapeutic strategy for CRC.
Main Methods:
- Analysis of genetic alterations in CRC.
- Investigation of NF-kappaB and AP-1 pathway activation in CRC cells.
- Assessment of the impact of these pathways on angiogenic and invasive factors.
- Evaluation of inflammatory mediator production in CRC.
Main Results:
- NF-kappaB and AP-1 pathways are implicated in the genetic alterations driving CRC.
- These transcription factors promote angiogenesis and invasion, contributing to CRC metastasis.
- Deregulated NF-kappaB and AP-1 function in CRC cells leads to increased inflammatory mediator production.
Conclusions:
- NF-kappaB and AP-1 signaling pathways are key drivers of colorectal cancer progression and metastasis.
- Their role in promoting angiogenesis, invasion, and inflammation makes them critical targets.
- Inhibiting NF-kappaB and AP-1 represents a rational therapeutic approach for novel CRC treatments.

02:07Tumor Progression
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...

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.

02:21Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
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...
01:25Mutagenicity 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...
