NO Pain! No Cancer? The Crosstalk Between Nociception, ROS, and Cancer Development

Transient receptor potential (TRP) channels, particularly those involved in nociception (nociceptive TRP channels), are implicated in both pain and cancer development. Activation of these channels by diverse stimuli triggers calcium influx, leading to mitochondrial oxidative stress and reactive oxygen species (ROS) accumulation. This ROS production contributes to both nociceptive signaling (causing pain) and aging processes, including genomic instability, a key driver of carcinogenesis. Although a direct causal link between pain and cancer onset remains elusive, the shared involvement of nociceptive TRP channels strongly suggests a correlation. This opinion article proposes targeting the crosstalk between nociceptive TRP channels and ROS as a promising therapeutic strategy to mitigate cancer and cancer-associated pain simultaneously. While further research is needed to definitively establish a causal relationship between pain and cancer risk, the available evidence suggests that inhibiting this pathway may offer significant benefits for both cancer prevention and treatment.
