Vaginal secretory proteome dynamically changes across the early and mid-trimesters of pregnancy

ABSTRACT: This study investigates the dynamic alterations in high vaginal fluid (HVF) proteome and its correlation with physiological changes during progression of term pregnancy. The HVF samples were collected at three time points as defined as V1 (6-12 weeks), V2 (18-20 weeks) and V3 (26-28 weeks) and SWATH-MS strategy were applied to profile changes in protein expression at early and middle stage of pregnancy. Using in-house generated HVF-specific protein library, 61 proteins (>1.5 fold at V2/V1 or V3/V1, q-value <0.05) changed as a function of gestational age. The stage-specific expression pattern of these proteins was mainly associated with the biology of cervical remolding, fetal development and microbial defense.
