Table 1. Comparative analysis of genetic and environmental factors influencing prostate cancer outcomes.
AHR: Aryl Hydrocarbon Receptor; AR: Androgen Receptor; PAHs: Polycyclic Aromatic Hydrocarbons; CAG: Cytosine-Adenine-Guanine.
Factor | African American Men | Caucasian Men | Impact on Prostate Cancer Outcomes |
AHR Expression | Higher levels in prostate cancer tissues. | Lower levels. | May drive more aggressive tumor behavior in African American men. |
AR Gene Polymorphisms | Shorter CAG repeats leading to increased AR activity. | Longer CAG repeats, typically associated with lower AR activity. | Shorter CAG repeats in African American men contribute to higher AR signaling and potentially more aggressive cancer. |
Environmental Exposures | Greater exposure to PAHs and dioxins due to socioeconomic factors. | Less exposure in general. | Increased exposure in African American men may amplify AHR activity, leading to more aggressive cancer. |
Access to Healthcare | Limited access, often presenting with more advanced disease. | Better access, earlier diagnosis. | Disparities in access lead to later-stage diagnoses and poorer outcomes in African American men. |
