Tributyltin exposure during gestation and lactation changes the hormone profile of the offspring in a sex- and age-dependent manner

Gaspar de Moura Egberto , Cristina Lisboa Patricia , Aparecida Miranda Rosiane

The ingestion of marine foods is a potential route of contamination by tributyltin (TBT), a biocide organotin used as an antifouling in boat paints. TBT causes a phenomenon known as imposex, that induces, for instance, the irreversible appearance of male sexual characteristics in gastropod females. In mammals, TBT also directly impairs the sexual development. In fact, it is known that TBT can affect women in reproductive age. Our aim was to study whether the maternal exposure ...

Effects of perinatal tributyltin exposure in Wistar rats on body parameters, insulin, leptin, milk composition and ultrastructure of the pancreatic islets in dams and offspring

Aparecida Miranda Rosiane , Vieira de Andrade Cherley Borba , Gaspar de Moura Egberto , Lisboa Patricia Cristina

Tributyltin (TBT) is a biocide organotin compound widely used as an antifouling in boat paints. This substance is a factor of contamination to water and food, especially marine fish. As an endocrine disruptor, TBT can interact with hormonal pathways and can induce gonadal dysfunction and glycemic dyshomeostasis; however, the effects caused by maternal exposure to TBT are scarce. Here, we investigate maternal exposure to low dose of TBT, considered safe, during pregnancy and la...

Maternal caffeine intake at low doses causes hormonal and metabolic changes in the offspring in a sex-dependent manner

Cristina Lisboa Patricia , Lopes de Souza Luana , Aparecida Miranda Rosiane , Gaspar de Moura Egberto

Caffeine crosses the placenta and mammary barrier and can affect the offspring metabolism and endocrine system from heavy caffeine users. Here, we tested the impact of a safe dose of maternal caffeine (200-300 mg/day) on plasma hormone of offspring from both sexes at different ages (weaning, puberty and adulthood). For this, pregnant Wistar rats received caffeine (25mg/kg/day) by gavage or vehicle during gestation (GEST group), lactation (LACT group) or both periods (G+L group...
