Dbp-flox Mouse

Dbp can refer to multiple entities. One is the Vitamin D binding protein, which is a multifunctional protein present in blood. It is an actin-sequestering protein, binding to actin subdomains 1 and 3, blocking the fast-growing side of actin monomers, and effectively interfering with actin-filament formation [5]. Another refers to Dibutyl phthalate, an endocrine-disrupting chemical widely used in industry [2].

In the context of Dibutyl phthalate, studies show it has detrimental effects. In rats, co-exposure to DBP and BaP causes more severe kidney injury than single-exposure, through promoting pyroptosis of renal tubular epithelial cells regulated by TLR4/NF-κB signaling [1]. In mouse Leydig cells, DBP induces ferroptosis via upregulating Sp2, which promotes Vdac2 transcription, while melatonin alleviates this by inhibiting Sp2/VDAC2 signals [2]. Pre-conception exposure to DBP in rodents impairs spermatogenesis by activating NF-κB/COX-2/RANKL signaling in Sertoli cells [3]. Also, in zebrafish, DBP exposure during embryonic development causes craniofacial defects [4].

In conclusion, the effects of Dbp (Dibutyl phthalate) are diverse and involve multiple biological processes and disease-related conditions. These findings from in vivo studies on animals like rats, mice, and zebrafish help understand its role in causing damage to organs such as the kidney and testis, as well as affecting embryonic development.
