Fourier transform infrared spectroscopy (FTIR) imaging has been applied to investigate biochemical differences
between salivary glands from control and hypertensive rats. Male Sprague–Dawley rats were
divided into two groups including a control group and another hypertension group that were treated
orally, with N-nitro-L-arginine methyl ester (L-NAME) via drinking water for 3 weeks to develop hypertension.
In the control group, rats were treated with only drinking water for 3 weeks. The formalin-fixed
paraffin embedded tissue specimens from submandibular and sublingual glands were analysed with a
FTIR focal plane array imaging spectrometer and multi-composite images of all tissue sections were analysed
simultaneously using Unsupervised Hierarchical Cluster Analysis (UHCA) and the extracted spectra
were further analysed using Partial Least Squares Discriminant Analysis (PLS-DA). In general, hypertension
affected salivary gland tissues were characterised by higher concentrations of triglycerides as evidenced
by an increase in the 1745 cm−1 band. Higher concentrations of carbohydrates and proteins were also
observed in the hypertensive group along with a decrease in bands associated with nucleic acids. PLS-DA
scores plots provided good differentiation in sublingual gland tissues between control (n = 3734 spectra)
and hypertension (n = 4538) and also in submandibular gland tissues between control (n = 5051) and
hypertension (n = 4408). We have shown that FTIR imaging can be used to differentiate the macromolecular
information between physiological and pathological conditions in tissue biopsy specimens. In the
next phase, we will investigate the infrared predictive markers of hypertension in biofluids including serum
and saliva using attenuated total refection spectroscopy. |
