Evaluation of the individual CpG sites based on multiple linear regression models suggested that associations were strongest with four of the seven individual CpG sites (CpG1: -1.5%; 95% CI: -3.1, 0.10%; p = 0.06; CpG2: -1.4%; 95% CI: -2.8, -0.03%, p = 0.05; CpG3: -1.3%; 95% CI: -2.7, -0.008%, p = 0.05; and CpG5: -1.8%; 95% CI: -3.4, -0.09%, p = 0.04) (Figure 2).
Methylation at the CpG2, 3, and 5 sites, which flank the transcription factor sequence as well as the TATA box region, was significantly lower in association with an IQR increase in second-trimester [PM.sub.2.5] air pollution.
Measurement Mean (range) 3-NTp (nM/mg protein) (a) 3,703 (100-23,681) LEP methylation (%) CpG1 10.0 (0.53-42.9) CpG2 12.7 (0.66-38.0) CpG3 8.5 (0.91-34.9) CpG4 61.5 (33.5-88.6) CpG5 13.6 (2.0-34.9) CpG6 13.5 (1.1-38.2) CpG7 22.3 (0.52-47.6) (a) 3-Nitrotyrosine, geometric mean (range), n = 313.
Hypermethylation was seen in both supplementation groups at CpG4 CD + EGCG (172%) and HFD + EGCG at CpG2 with an increase of 80% normalized to, respectively, CD or HFD (p [less than or equal to] 0.01).
In colon cells the methylation status of MLH1 showed a significant reduction at CpG2 in HFD compared to CD (60%; p [less than or equal to] 0.01).
Methylation of CpG2 (adjusted P = 0.013) and CpG3 (adjusted P = 0.039) was significantly lower in healthy males than in healthy females after adjusting for confounding factors (Table 3 and Figure 2).
In addition, we found that methylation of CpG2 and CpG3 was significantly different between males and females in healthy controls.
where y was the CpG of interest (i.e., CpG1, CpG2
, or CpG3), [P.sub.total M] was the arithmetic sum of all P, where the CpG of interest methylation status was M, and where [P.sub.total U] was the arithmetic sum of all P where the CpG of interest methylation status was U.

MSQMA provides combined methylation output from 10 CpG sites (CpG2
to -12), including those with methylation reported to change with age (16), those that have stable methylation over time, and 3 additional CpG sites for which the methylation status could not be analyzed by MALDI-TOF MS owing to their fragments being too large.
