Chronic inflammation is a potential systemic risk factor for many bladder
dysfunctions, including interstitial cystitis (IC). However, the underlying
mechanism through which a healthy bladder protects itself from inflammatory
triggers remains unknown. In this study, we identified odor compounds in urine
obtained from IC patients and healthy controls. Using comprehensive solid-phase
microextraction-gas chromatography-time-of-flight-mass spectrometry
(SPME-GC-TOF-MS) profiling and bioinformatics, we found that levels of urinary
volatile metabolites, such as menthol, were significantly reduced in IC patients,
compared to healthy controls. In an attempt to understand the mechanistic meaning
of our volatile metabolites data and the role of menthol in the immune system, we
performed two independent experiments: (a) cytokine profiling, and (b) DNA
microarray. Our findings suggest that lipopolysaccharide (LPS)-stimulated
inflammatory events, such as the production and secretion of inflammatory
cytokines (e.g., TNF-?, IL-6, and IL-1?) and the activation of NF-?B and
associated proteins within a large signaling network (e.g., Akt, TLR1, TNFAIP3,
and NF-?B), are suppressed by the presence of menthol. These findings broaden our
knowledge on the role of urinary menthol in suppressing inflammatory events and
provide potential new strategies for alleviating both the odor and inflammation
associated with IC.
