Summary
This summary is machine-generated.Polycyclic aromatic hydrocarbons (PAHs) were found to inhibit apoptosis and increase aryl hydrocarbon receptor (AhR) expression in nasopharyngeal carcinoma (NPC) cells. These findings suggest PAHs contribute to NPC development by regulating AhR.
Area Of Science
- Oncology
- Environmental Health
- Molecular Biology
Background
- Nasopharyngeal carcinoma (NPC) presents with late diagnosis and metastasis, with unclear pathogenesis.
- Polycyclic aromatic hydrocarbons (PAHs), environmental contaminants, are mutagenic and carcinogenic, but their role in NPC requires further study.
Purpose Of The Study
- To investigate the effects of PAHs on NPC cell behavior and the expression of aryl hydrocarbon receptor (AhR).
- To elucidate the role of AhR in PAH-induced changes in NPC cells.
Main Methods
- CNE-2 NPC cells were exposed to PAHs.
- Gene and protein expression of AhR and CYP1A2 were analyzed using qRT-PCR and Western Blot.
- Cell proliferation, migration, invasion, and apoptosis were assessed using CCK-8, Wound-Healing Assay, Transwell, and Flow Cytometry.
Main Results
- PAHs increased AhR expression and inhibited apoptosis in NPC cells.
- PAHs did not significantly alter NPC cell proliferation or migration but weakened invasion.
- Co-treatment with PAHs and ITE counteracted PAH-induced AhR upregulation and increased apoptosis.
Conclusions
- PAHs inhibit apoptosis and promote AhR expression in nasopharyngeal carcinoma cells.
- PAHs appear to influence NPC occurrence and progression via AhR regulation.
- Targeting AhR may offer a potential therapeutic strategy for NPC.

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

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...
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...
Some GPCRs transmit signals through adenylyl cyclase (AC), a transmembrane enzyme. AC helps synthesize second messenger cyclic adenosine monophosphate (cAMP). AC catalyzes cyclization reaction and converts ATP to cAMP by releasing a pyrophosphate. The pyrophosphate is further hydrolyzed to phosphate by the enzyme pyrophosphatase, which drives cAMP synthesis to completion. However, cAMP is rapidly degraded to 5′ AMP by the enzymes phosphodiesterase (PDE), preventing overstimulation of...
Simple aryl halides do not react with nucleophiles. However, nucleophilic aromatic substitutions can be forced under certain conditions, such as high temperatures or strong bases. The mechanism of substitution under such conditions involves the highly unstable and reactive benzyne intermediate. Benzyne contains equivalent carbon centers at both ends of the triple bond, each of which is equally susceptible to nucleophilic attack. This 50–50 distribution of products is...
