Figure Lengend Snippet: Effect of prenatal maternal stress (PMS) regulation of Bdnf splice variant and total Bdnf expression in the F1 and F2 generations. Quantitative real–time PCR analysis showed that PMS/oxytocin mediated alterations in the expression of Bdnf exon—III, IV and exon—VI transcripts. The analysis showed that PMS differentially altered the expression, level of exon-III increased, and exon-IV and VI decreased in (A) F1 (PMS) and (D) F2 (PMS) offspring. Administration of oxytocin minimized the PMS-induced effect, decreased exon-III, and increased exon-IV levels in (A) F1 (PMS+OXT) and (D) F2 (PMS+OXT) offspring. Furthermore, the level of total Bdnf was decreased by PMS in the PMS F1 and PMS F2 offspring, and oxytocin administration reverse the PMS induced effect. Correlation analysis showed that the level of total Bdnf mRNA significantly associated reference (B,E) , working memory (C,F) in F1 and F2 offspring. Data are represented as mean ± SE, and statistical significance is indicated by ** p < 0.01; *** p < 0.001; NS, not significant.
