Table_1_Higher blood cotinine level is associated with worse cognitive functioning in non-smoking older adults.DOCX
IntroductionSecondhand smoke (SHS) is common in older adults; however, its cognitive effect is unclear. We aimed to examine the association between serum cotinine level and cognitive functioning among non-smoking older adults.Materials and methodsA total of 2,703 older adults aged 60 and above from the National Health and Nutrition Examination (NHANES) Survey 2011–2014 were included. Serum cotinine level was analyzed in the laboratory. A level ≤10 ng/ml and a response of “no” to the question “Do you currently smoke?” were used to select non-smokers. Cognitive functioning was measured using the Consortium to Establish a Registry for Alzheimer’s disease Word Learning subtest (CERAD-WL) immediate and delayed recall tests, the Animal Fluency test (AFT), and the Digit Symbol Substitution test (DSST). Multivariable linear regression models were constructed to examine the association between serum cotinine level quartile and test-specific and global cognition z scores adjusting for age, race/ethnicity, education, depressive symptoms, body mass index, alcohol use, smoking history, prevalent coronary heart disease (CHD), stroke, and systolic blood pressure.ResultsAbout half of the participants (mean age 70.5 years) were female (53.6%), non-Hispanic White (48.3%), and completed some college and above (50.2%). Multivariate linear regressions with a reference group being those in the 1st quantile (lowest) showed that participants in the 4th quartile (highest) of serum cotinine level had lower immediate recall [β = −0.16, 95% confidence interval (CI) = −0.29, −0.03], AFT (β = −0.19, 95% CI = −0.33, −0.05), DSST (β = −0.27, 95% CI = −0.39, −0.15), and global cognition (β = −0.26, 95% CI = −0.39, −0.14) z scores. Participants in the 3rd quartile had lower immediate recall (β = −0.16, 95% CI = −0.30, −0.02) and global cognition (β = −0.16, 95% CI = −0.29, −0.02) z scores. Participants in the 2nd quartile had lower delayed recall z scores (β = −0.16, 95% CI = −0.29, −0.02).ConclusionHigher serum cotinine level was associated with worse cognitive functioning in non-smoking older adults. Prevention and reduction of SHS in older adults may help protect their cognitive functioning.</p

Proteomic Quantification and Site-Mapping of <i>S</i>‑Nitrosylated Proteins Using Isobaric iodoTMT Reagents
<i>S</i>-Nitrosylation is a redox-based protein post-translational
modification in response to nitric oxide signaling and is involved
in a wide range of biological processes. Detection and quantification
of protein <i>S</i>-nitrosylation have been challenging
tasks due to instability and low abundance of the modification. Many
studies have used mass spectrometry (MS)-based methods with different
thiol-reactive reagents to label and identify proteins with <i>S</i>-nitrosylated cysteine (SNO-Cys). In this study, we developed
a novel iodoTMT switch assay (ISA) using an isobaric set of thiol-reactive
iodoTMTsixplex reagents to specifically detect and quantify protein <i>S</i>-nitrosylation. Irreversible labeling of SNO-Cys with the
iodoTMTsixplex reagents enables immune-affinity detection of <i>S</i>-nitrosylated proteins, enrichment of iodoTMT-labeled peptides
by anti-TMT resin, and importantly, unambiguous modification site-mapping
and multiplex quantification by liquid chromatography–tandem
MS. Additionally, we significantly improved anti-TMT peptide enrichment
efficiency by competitive elution. Using ISA, we identified a set
of SNO-Cys sites responding to lipopolysaccharide (LPS) stimulation
in murine BV-2 microglial cells and revealed effects of <i>S</i>-allyl cysteine from garlic on LPS-induced protein <i>S</i>-nitrosylation in antioxidative signaling and mitochondrial metabolic
pathways. ISA proved to be an effective proteomic approach for quantitative
analysis of <i>S</i>-nitrosylation in complex samples and
will facilitate the elucidation of molecular mechanisms of nitrosative
stress in disease
