Are virulence genes a signature of the microbiome in the colorectal tumor microenvironment?
This work identifies bacterial taxa significantly correlated with colorectal cancer, including a novel finding of an elevated abundance of Providencia in the tumor microenvironment. We also describe the predicted metabolic pathways and enzymes differentially present in the tumor-associated microbiome, and show an enrichment of virulence-associated bacterial genes in the tumor microenvironment. This predicted virulence enrichment supports the hypothesis that the microbiome plays an active role in colorectal cancer development and/or progression. Our results provide a starting point for future prognostic and therapeutic research with the potential to improve patient outcomes.
The results of the study showed that oxybutynin and tolterodine prolonged the simple reaction time. The prolonged simple reaction time may suggest a perceptive impairment. The potential for perceptive impairment as a side effect of oxybutynin and tolterodine might suggest a negative impact on the rehabilitation interventions and the activities of daily living because of central nervous system effects.
