Although LINC01019 was not directly highlighted in the placental abruption analysis, the emerging importance of noncoding regulatory elements in complex disease mechanisms implies that aberrant regulation (including potential alterations in methylation) of loci such as LINC01019 might also contribute to placental biology and its disorders. In summary, while direct functional data on LINC01019 remain limited in these reports, the association of its potential differential methylation with transcriptional changes in target tissues underscores its candidate role in modulating disease-related pathways in both smoking-induced lung pathology and placental dysfunction.\n "}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Mi Kyeong Lee, Yoonki Hong, Sun-Young Kim, et al.
