Abstract
Objective
Baicalin (BC) is a flavonoid reported to have various pharmacological activities, including antioxidant, anti-cancer, anti-inflammatory, anti-allergy, immune regulation, and anti-diabetic. This study examines the probable mechanism for gestational diabetes mellitus (GDM) brought on by streptozotocin (STZ) and the impact of BC on fetal development via AGEs (advanced serum glycation end products) and RAGE (the role of advanced glycation end products).
Material and Method
STZ has been used in the current experimental study to induce diabetes mellitus in pregnant animals (gestational diabetes mellitus). GDM pregnant animals were separated into five groups and were treated with BC in a dose-dependent pattern for 19 days. At the end of the experiment, the fetus and blood samples were drawn from all the pregnant rats to assess the biochemical parameter as well as AGE-RAGE.
Result
Administration of BC at varying doses leads to enhancement in the weight of the fetus body and placenta while gestational diabetic pregnant animals induced by STZ had a lower weight of the fetus body and placenta. The dose-dependent pattern of BC also enhanced fasting insulin (FINS), high-density lipoprotein (HDL), serum insulin, and hepatic glycogen. It also significantly enhanced the content of the antioxidant profile and pro-inflammatory cytokines and modulated the gene expression (VCAM- 1, p65, EGFR, MCP-1, 1NOX2, and RAGE) in various tissues in gestational diabetes mellitus pregnant rats.
Conclusion
Baicalin demonstrated the potential impact on the embryo’s development via the AGE-RAGE signaling pathway in STZ-induced GDM pregnant animals.

Practical Application
It is well known that the prevalence of gestational diabetes is rising globally. Baicalin is traditional Chinese medicine and is used in diabetes management. The present study describes the potential effect of baicalin on gestational diabetes mellitus in pregnant animals via an underlying probable mechanism. The result also supported the efficacy of BC in GDM rats in a dose-dependent manner via improving biochemical analysis, inflammation and oxidative stress, and the AGE-RAGE signaling pathway. We can conclude from the findings that baicalin may be a protective medication for the management of gestational diabetes mellitus.
Statement of Novelty
Our results suggest the efficacy of baicalin in gestational diabetes mellitus rats. It increases the weight of the fetus’s body and placenta. It also elevates the level of lipid profile, serum, and glycogen in a dose-dependent manner. It was also found effective in increasing the antioxidant parameter and inflammatory profile and attenuating the gene expression via AGE and RAGE signaling pathways. It can be used in clinical trials and lead to technology transfer for the welfare of the society in the management of diabetes mellitus.
